Hello, I currently have some people trying to authenticate throuqh the port 25. I suppose they try out default passwords. I get up to 100 attempts in a few tens of seconds and they retry every hour. Fai2ban fails to detect and block them. There are also the ports 465 (SMTPS) and 587 with SASL authentication which may fail. I currently don't have any failed connection attempts on these ports, but this is just a matter of time. I'm ready to switch from fail2ban to sshguard, but your web site doesn't report a support of Postfix. This is a bit surprizing since many people use Postfix. So my question is if sshguard supports Postfix protection. -- Bien cordialement, Ch.Meessen |
