The waiting time is about 50s on my CentOS box now. "yum remove openssh* "and "yum install openssh*" can't make it right. "mv ~/.ssh{,.bak}" not works either. Here comes my tcpdump log, I am not an expert on SSH, Can anyone here get me out of this?
The answering sshd will do a reverse DNS lookup on the connecting IP address. That's about the right time to wait for timeouts from 2 DNS servers if they don't respond.
