Re: [CentOS] Problem with ssh disconnecting

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.
