I keep seeing a flood of messages when I run dmesg -a that look like this: mail sshd[1831]: warning: /etc/hosts.allow, line 2: can't verify hostname: getaddrinfo(ip223.hichina.com, AF_INET) failed Is there anything I should be doing to make sure the server isn't compromised? It is a mail server running postfix / dovecot I have pf set up and am also running a program called sshguard. I am kind of at a loss. It looks like I am under attack but I don't know what to do about it. Any help is greatly appreciated Thanks in advance Mark Moellering mark@msen.com
