When I try to ssh to particular machine/s in a list, The SSH command happens to be freezing. I tried out setting ssh timeout. But then also it's freezes even after the timeout.
In verbose mode :
OpenSSH_3.9p1, OpenSSL 0.9.7a Feb 19 2003 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to x358.x.server.com [10.x.x.x] port 22. debug1: fd 3 clearing O_NONBLOCK debug1: Connection established. debug1: identity file /export/home/sqlrpt/.ssh/identity type -1 debug1: identity file /export/home/sqlrpt/.ssh/id_rsa type -1 debug1: identity file /export/home/sqlrpt/.ssh/id_dsa type 2
At this point it freezes.
A work around I thought was to create a child process for each ssh calls and if the process doesn't respond after a timeout - Kill it. But are there any less complex ways, so that I can accommodate it in a shell script itself rather than going for a C/C++ program ?
