Running CentOS 7 on workstation and having a problem with ssh disconnects. My ssh_config contains:
Host * TCPKeepAlive yes ServerAliveInterval 30 ServerAliveCountMax 300
and sshd_config on the server contains:
TCPKeepAlive yes ClientAliveInterval 60 ClientAliveCountMax 300
Have I missed any setting needed to prevent these random disconnects? I don't think there is anything wrong with the network card, the driver, or the cable, since if I am on a VPN connection via another server, the VPN and any ssh connection stay up indefinitely.
Thanks.
Another poster has provided some possible reasons for the disconnections. Whatever the cause, autossh (from the epel repo) is a good workaround.
Not that this happens while I do large scp file transfers that may take more than half an hour, simply restarting an ssh session is not going to help since I will lose the file transfer.
In that case sftp with the '-a' option would be a better choice.
