Taking photos of the moon with an iPhone

One of the best methods of taking photos of stars, planets and satellites is with a webcam, like the old Toucam Pro, and processing with Registax. That’s not the easiest method though, and when you want photos of the moon, an iPhone does the job very well.

Securing WordPress using fail2ban

With the recent dictionary attacks on WordPress, I installed a simple configuration for fail2ban that requires no access to the backend of each site you host. This should protect all the sites on a server from being attacked by the massive botnet that’s doing the rounds.

Add this to /etc/fail2ban/jail.conf

enabled = true
port    = http,https
action   = iptables[name=WP, port=http, protocol=tcp]
filter  = apache-wp-login
logpath = /var/www/vhosts/*/statistics/logs/access_log
maxretry = 3

The logpath should include every access log on your server, or at least the WordPress ones. Mine is ideal for Plesk installs on Linux.

Add this to /etc/fail2ban/filter.d/apache-wp-login.conf

# Fail2Ban configuration file
failregex = <HOST>.*] "POST /wp-login.php
ignoreregex =

Restart fail2ban and you’re set.
