Dear all, I have recently reinstalled my server (SL4.1, x86_64). I have encountered ssh timeout problem again. In the sshd_conf I have uncommented "TCPKeepAlive yes" and I have set "ClientAliveInterval 60". But I ketp got kicked out. I forgot what I did in the previous installation. The network hardware are the same, so there is no change in external firewall. What can be the problem?
