For many Linux users this will be a “Thank you, Captain Obvious” type of post, but it’s one of those things that some Webmin users might not realize. If you use Webmin’s “Linux Firewall” configuration page to configure the iptables firewall in Linux, and you click “Apply Configuration”, it will remove fail2ban‘s rules from your active iptables configuration. So, you must go to a Linux command prompt and enter service fail2ban restart — UNLESS you make a small change in the Webmin “Linux Firewall” configuration.
From the Webmin “Linux Firewall” main page, click Module Config, then on the configuration page, in the “Configurable options” section, look for the line “Command to run after applying configuration.” Click the button next to the text box on that line, and in the text box enter service fail2ban restart and then click the Save button at the bottom of the page. That’s all you need — now every time you make a firewall change and click “Apply Configuration”, it will automatically restart fail2ban for you.

If you’ve installed Midnight Commander and haven’t changed the default colors, when you try to access a dropdown menu you may see this:
Midnight Commander — Original Colors
REALLY hard to read that menu, isn’t it? Wouldn’t you rather see this?
Midnight Commander — Changed Colors
To fix the unreadable menus, just make sure Midnight Commander is not open, then use any text editor (such as nano) to open ~/.mc/ini:
nano ~/.mc/ini
Assuming that there is no existing [Colors] section in the file, just add this at the bottom of the file (if the second line exceeds the blog column width, just use copy and paste to get it all):
If there is an existing [Colors] section, you can try tweaking it using the parameters shown above. If you have a very recent version of Midnight Commander (which you probably will have if you are running Ubuntu), then instead of menu= you’ll need to use menunormal=, as shown here:
Note that for some reason the base_color parameter must appear, or the other items are ignored. Save the change, exit the editor, and open Midnight Commander. If you then close Midnight Commander, you may find that the position of the [Colors] section has moved within the ini file — apparently Midnight Commander rewrites the file when you close it — but if you don’t like the changes you can remove the [Colors] section to reverse the change.
