Fail2ban settings after changing ssh port

Question

I switched my ssh port to 22000 and I changed the port settings in /etc/fail2ban/jail.local to specify to ban on both 22 and 22000 but when I tried failing to login 6 times, my connection was cutoff but was able to try logging in again immediately.

It appears my IP wasn't banned for an hour per the default bantime I set.

Is there something wrong with how I configured this?

# "bantime" is the number of seconds that a host is banned.
bantime  = 3600

[ssh]

enabled  = true
port     = ssh,22000
filter   = sshd
logpath  = /var/log/auth.log
maxretry = 6

Thanks.

Answer 1

What I have seen by trying myself is that restarting the fail2ban daemon doesn't make it reload its configuration file. (Unlike most other daemons under linux... I don't even know how it manages to save its configuration when stopped. Temporary files I guess)

The following command will solve your problem :

fail2ban-client reload

This executable can be used to poll status and other interaction with the daemon.
