Block IP with fail2ban from command line
Raw
fail2ban_block-ip-from-commandline.md

A quick block for clients that bother you somehow or do malicious stuff.

List your jails

 sudo fail2ban-client status

Choose the jail you want to block the IP from/add it to.

Block the IP

 sudo fail2ban-client -vvv set [JAILNAME] banip [IP]

Replace [JAILNAME] with a jail from first list and [IP] with the IP address to be blocked.

The block is not permanent and will be removed on reboot/restart of fail2ban.
