SSH failing when running mutiple ssh scripts at once
I am SSHing to Cisco routers and switches. SSH fails if on one of the other scripts is hung trying to connect to a router or switch that is slow to respond.
I have done this in other networks but I was not in charge of the Linux server.
Is there a setting in SSH client that will allow multiple ssh processes to be trying to connect at the same time?

I'm afraid I probably don't understand the question - but are you talking about multiplexing?

Also - you can configure a ConnectTimeout value for ssh that might help with the issues you are seeing.

Another possibility... See http://linux.die.net/man/5/sshd_config for the MaxSessions value, This value Specifies the maximum number of open sessions permitted per network connection. That man page claims the default is 10.
