Hi all I have an ADSL modem which reboots when there is a power cut and the inverter (UPS) kicks in. Internet access is down for a duration of 1 to 2 minutes while the modem boots. I have many SSH tunnels and shells active. Due to the default "TCPKeepAlive On" setting, these sessions are terminated almost immediately. I tried the following configuration: sshd_config on server:

Hi OpenSSH team, We found that openssh5.0 has a bug with the "ServerAliveInterval" and "ServerAliveCountMax" options. This function doesnt work at all, which means when the Maxtime reached, the ssh will not kill the connection and prompt the infomation "Connection Timedout" as it used to do. We built the openssh5.0p1 code on the a Linux box, and use the

Hi, In the last several years, I noticed an annoying problem with ssh: Long-running ssh connections are automatically disconnected after just a few minutes of inactivity. This problem effects both interactive sessions (using ssh without screen(1) became almost impossible...) as well as ssh port forwarding and the likes. I never noticed this problem until about 6 years ago, but since then have

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

Thanks for rsync - it's great! I use it for all my backups. I use rsync via SSH.

I am of the opinion that ClientAliveCountMax should really force a disconnection from the testing side when a ping-pong control packet retransmission would exceed the max counter. But it appears to need TCP to timeout to occur from that point, for the process/tty to close. For SSH client options: -o ServerAliveInterval=60 -o ServerAliveCountMax=3 Should cause the client to force an

I don't believe you've said: are the disconnects happening during periods of idleness on the connection, or periods of activity? If idleness, some device or script could be actively doing a disconnect-on-idle.

Hello, I have a bandwidth-constrained connection that I'd like to run rsync over through an SSH tunnel. I also want to detect any network drops pretty rapidly. On the servers I'm setting (via sshd_config): ClientAliveCountMax 5 ClientAliveInterval 1 TCPKeepAlive no and on the clients I'm setting (via ssh_config): ServerAliveCountMax 5 ServerAliveInterval 1 TCPKeepAlive no After
