Hi, I've configured fail2ban with action, filter for my php application.

My app output log like this:

unknown user foo (192.x.x.x)

My jail conf:

[php-app-login] enabled = true port = 80 protocol = tcp filter = php-app-login logpath = /var/www/php-app-login/var/logs/dev.log findtime = 3600 bantime = 86400 maxretry = 3 ignoreip = 127.0.0.1/8

My filter definition:

[Definition]

failregex = unknown user .* (<HOST>) ignoreregex =

It works well, but I like fail2ban add comment in iptables rule when add ban IP.

For example:

iptables -A INPUT -p tcp --dport 80 -m comment --comment "Ban foo" -j DROP

iptables -L -n -v

Chain INPUT (policy ACCEPT 94 packets, 23457 bytes) pkts bytes target prot opt in out source destination 0 0 DROP tcp -- * * 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 /* Ban foo */

I've googled and I think something needs to be changed in action but I can't find how to pass the user variable to that action.

Something along the following lines, though I could be wrong, or incomplete. Create a local, customized, action.d/iptables-multiport.local where: 1. you set up the rule with the commment? 2. if I understood you correctly, a possible alternative for the comment would be to have a dedicated chain.

[Definition] # Have a dedicated chain for php-app-login. # f2b-php-app-login is expected to exists. Possibly set up by whatever # sets iptables. actionstart = actionstop = iptables -F f2b-<name>

Again, I could be wrong, or incomplete.
