I remotely tried to login to server with ssh but forgot password and now locked out. I searched for know_hosts but can not find it. How do I remove the lock?

Also, I have a couple of issues. Here are the error messages:

Also, I cannot get mail to receive. Itos as if something is blocking it. Any thoughts on how to trouble shoot it/

thanks

It seems fail2ban lock you out.
You need to restart the server to clear the iptables rules.
You can also change permanent ban to seconds in /etc/fail2ban/jail.conf.
Also if your ip you use to login is static you can add it to ignore it, even if its failing to login.

thanks for the help. Very tired and frustrated right now.

It seems as if something is blocking inbound. I did not start sms firewall, but does it start on boot?

Could blacklist be stopping inbound?

I've had all this working under 1.4.1, so I am really frustrated to why I can't get it to work under 1.4.2.

any ideas?

Have you reboot the server?
If you trying to test from your IP Fail2ban adds a drop all anywhere from your IP, so it's useless to try anything unless you reboot the server.

thanks for the help. I am in the process of fixing things now.
