similar to: [Bug 1465] New: "ServerAliveInterval" and "ServerAliveCountMax" doesnt work in openssh50?

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

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

Hi openssh-unix-dev subscribers :) I have found that ServerAliveInterval & ServerAliveCountMax have some bug. Basically the ssh-alive check function (that verify the peer is alive) is called only if no data at all gets into ssh (when it should work only for server channel).I am pretty sure developers know about this ..anyway I have tried to fix this issue. Here is the patch: diff -rNu

Hi, I have a client on a Windows machine that connects through openssh on a linux server. I have this script (tunnel.cmd): @echo off :RUN echo Connecting?

Dear Sirs: Thank you so much for your help. I have now created both the client and server for resumable nx sessions using the ServerAliveInterval option to disconnect after several seconds of server inaccessibility. I am now working on an nxssh "substitute", which at this point seems fairly straightforward. However, when I spawn ssh, I need to know whether: (a) it exited because of

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

What is the canonical link to Reference of "ServerAliveInterval"? Background: I want to write an answer at serverfault (Q-A Site). I want to avoid copy+pasting. I would like to lead the new comer to the canonical reference. Regards, Thomas G?ttler -- Thomas Guettler http://www.thomas-guettler.de/

Hello, I am testing ssh with occasional network disconnection between server and client during these days. I found ssh sometimes hangs if the disconnection happens after the connection is established but before ssh_exchange_identification completes. The ssh configuration files show that both client and server alive options are set. In /etc/ssh/ssh_config: # Send keepalive messages to the server.

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.

You could try using an automounter, like autofs, in combination with sshfs. It'll be slower, possibly a lot slower, but it should be more reliable over an unreliable connection. I've been using: remote -fstype=fuse,allow_other,nodev,noatime,reconnect,ServerAliveInterval=15,ServerAliveCountMax=40,uid=0,gid=0,ro,nodev,noatime :sshfs\#root at remote.host.com\:/ BTW, I'm not sure

Explico mi situaci?n, tengo un servidor centos 5.5, con sistema ssh que viene por defecto la versi?n 4.3. A este servidor se conectan alrededor de 100 terminales, cada uno de estos terminales levantan 3 tuneles contra el
