I am using Parallel::ForkManager to run multiple ssh sessions on various remote
hosts. It is working fine.
Sometimes I have a problem: problem is in Net::OpenSSH module that, for
whatever reason, when far end does not respond the module does not close the
SSH connection (i.e. timeout is not working).
and, i am running ssh sessions inside forkmanager forked sessions. so i am
wondering if there is anything I can use from forkmanager to terminate a child
session based on some timeout value?
I read Parallel::ForkManager documentation, but to me it looks like i can not.
is there anyone more experienced on this, who can help?
basic logic:
foreach $host (@hostlist) {
my $pm->start($host) and next;
my $ssh = Net::OpenSSH->new($host,
master_opts => [-o =>
'StrictHostKeyChecking=no',
-o => 'ConnectTimeout 30'],
);
...then some useful work thru ssh....
...
undef $ssh;
$pm->finish;
}
ty.
