Hi,

I am quite new to Perl, and I am using smokeping.

I created a RemoteTraceroutePing Probe based on the RemoteTraceroute one. Basically, the idea is to create a SSH connection to a remote host, and fire regularly traceroute commands and read the output. So far, I was able to have something that works,, and it works with one or two probes, but with more than that, all standard outputs are mixed up.


I do create the connection this way: 
# $ssh_sr contains the remote host like user@host
open my $def_in, '<', '/dev/null';
$self->{ssh} = Net::OpenSSH->new($ssh_sr, default_stdin_fh => $def_in)
+;

Then, the different targets (Traceroute commands) are called like this (in parallel): 
# @cmd contains the traceping command to launch remotely via the exist
+ing SSH connexion.
my $killed;
my (undef, $f_stdout, $f_stderr, $pid) = $self->{ssh}->open3(@cmd);
while (<$f_stdout>){
   # OUTPUT ANALYZED AND PROCESSED HERE
   $killed = kill(15, $pid);
   last;
}
waitpid $pid, 0;
close $f_stdout;
close $f_stderr;

The problem is, despite that I can launch several traceping simultaneously with individual pids, the f_stdout of one pid is receiving the stdout from others. How can I fix that ? Thank you

In reply to net::OpenSSH several commands, stdout are mixed up by Bolemo
