KeepAlive/ClientAliveInterval not working? Idle timeout.
I have set /etc/ssh/sshd_config with: KeepAlive yes ClientAliveInterval 3 However, no KeepAlive type messages seem to be sent. I've verified this by looking at the network lights, which don't flicker every 3 seconds. I am attempting to keep interactive ssh sessions alive longer. If don't type anything for about 2 minutes, the sessions close. If I ru...

ClientAliveInterval
Hi, I am having some trouble with the ClientAliveInterval server setting. My (C++) application fails to start an SSH channel to an OpensSSH server within this time-out period if it doesn't reply correctly to this 'keep-alive' no-op that is sent by the server. How is this no-op handled? I am using the libssh client library, and I could find no...

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. Th...

[Bug 3362] New: [RFE] Implement a mechanism to disconnect idle users
...riority: P5 Component: ssh Assignee: unassigned-bugs at mindrot.org Reporter: ggasparb at redhat.com Many security policies have a security requirement related to disconnect idle users from remote connections. So far, this requirement has been fulfilled by misusing the ClientAliveInterval and ClientAliveCountMax options by setting ClientAliveCountMax to zero. Newer version of openssh dropped completely this undocumented behavior and currently there is no other alternative to fulfill the requirement. This RFE is to add such mechanism where idle users are automatically disconnected f...

[Bug 2627] New: Documentation update: semantic of ClientAliveCountMax 0 unclear
...terminate an alive but idle session. However, this is not clear, as demonstrated by that email. It would be helpful to add something like >With ClientAliveCountMax == 0 there will be no "client alive packet" >sent and I will force a disconnection if there is no traffic within >ClientAliveInterval secs. to the section on ClientAliveCountMax or ClientAliveInterval. -- You are receiving this mail because: You are watching the assignee of the bug.

Login via Mac, Windows, Linux systems from different computers. 2. Modify sshd_config on the server as suggested by many posts: TCPKeepAlive yes ClientAliveInterval 60 3. Modify ~/.ssh/config file on my local computer: Host * ServerAliveInterval 60 4. Login ssh using -Y instead of -X. 5. add ?unset autologout? in my .cshrc. 6. I checked IP address with the internet administrator, and it works well. 7. add a file named autologout.csh with ?set autologout=0?. D...

FYI Incompatibilities between recent versions of OpenSSH and Sun SSH

It times out after 15 minutes of activity or inactivity. What I recommend is Stop using Sun SSH or changing all the OpenSSH servers to have the following definitions: ClientAliveInterval 1800 ClientCo...

Openssh connection closes from time to time. why?
...ervers. Since the move I had troubles with ssh open sessions. I am connecting from a windows machine via putty and then all of a sudden it saying something about connection closing. The OpenSSH version is: openssh-server-5.3p1-81.el6.x86_64.rpm I tired to configure: tcp_keep_alive TCPKeepAlive yes ClientAliveInterval 240 ClientAliveCountMax 50 Each one of them or all together seems to not solve the problem. It's not iptables issue since it was stopped and disabled. If someone have an idea of what can be done or checked I will be happy to hear about it. For now I have created a custom OpenSSH-6.1p1 RPM j...

IdleTimeout patch did not get in?

Enabling ServerAliveInterval by default
...ntly). If ServerAliveInterval is enabled by default, with a short (few minute) interval, we may also want to increase ServerAliveCountMax (which is by default only 3), although I'm not sure about this. I think we should also consider enabling by default the corresponding option in the server - ClientAliveInterval.
