Attached is a patch which adds a ConnectionTimeout option, and corrects the ConnectionAttempts documentation. Previously, ssh would try to make a connection ConnectionAttempts times, sleeping 1 second between tries. But each connection attempt could take a very long time to fail if the packets die before the get to the host. So if ssh is being run in a script or what-have-you, it might be...

...bunch of firewalls (joy ...) and so for connectivity tests, I'm using ssh (OpenSSH 2.x). I'm being lazy, and trying to avoid parallel tasks/threading, so I'm interested in reducing the amount of time OpenSSH will wait to connect to something before giving up. I've already set the ConnectionAttempts flag to 1, but am interested in reducing the amount of time it uses initially. From our boxes, the timeout seems to be abuot 60 seconds, but I haven't timed it yet, or groveled through the code enough to know for sure. Before I embark on a coding spree and hack at OpenSSH to do this, am I...

I am trying to set up port forwarding using the client of a multiplexed connection, but the client is dying. The connection paramaters I am using are as follows: for the master: /usr/bin/ssh -T -n -N -o ControlMaster=yes -o ControlPath=/var/run/autossh/control-%r@%h-%p.sock -o ConnectionAttempts=3 -o BatchMode=yes -o EscapeChar=none -o ExitOnForwardFailure=yes -o ServerAliveInterval=15 -o ForwardAgent=no -c arcfour -2 -x user at host.com for the client: /usr/bin/ssh -T -n -N -o ControlMaster=no -o ControlPath=/var/run/autossh/control-%r@%h-%p.sock -o ConnectionAttempts=3 -o BatchMode=yes...

Hi, I have a problem with a Linux box which I updated from 2.5.2p2 to 2.9p2 recently. It's running a tunnel started via inittab using a script which starts ssh -2 -N -o 'ConnectionAttempts 3600' -L <tunnel> $host This has run reliable with 2.5.2 over the last months. Now, after I have upgraded to 2.9p2, the tunnel is closed right after each attempt of an application to use the tunnel which is a cron job running each 5 minutes. So, now the tunnel is closed and restarted ea...

...ely, while the other takes 10 seconds. If I do several of these, some will not finish and return a "Connection closed" message. The pattern of which domU connections are slow or fail is not repeatable. Each of the domUs is fast when it is the only one being used. If I use "ssh -o ConnectionAttempts=10 ..." then some of the connections will work after a few _minutes_. This happens when the above is run both from a separate native Linux box (directly connected with a gigE crossover) and dom0. It also happens under both SuSE 9.3 running Xen 2.0.5c and Fedora Core 4 running Xen unstable....
