Thanks, I tried some of these changes to the 'open' line, but problems still choke the process: 

$pid = open( my $fr_child, '-|', @cmd) 
            or die("Can't launch $cmd[0]: $!\n");

[download]
fails with an error: Can't use an undefined value as filehandle reference at testSnmp2.pl line 192.

Tweaked to look like this 

$pid = open( my $fr_child, '-|', $snmpCmd)
            or die("Can't launch $cmd[0]: $!\n");

[download]
The open succeeds, but I get this error from the child proc 
Child exited successfully
!!!! Illegal seek / 0 /

[download]
and I get no data back.

Tweaked again to be 

        $pid = open( my $fr_child, $snmpCmd)
            or die("Can't launch $cmd[0]: $!\n");

[download]
I get the following response: Can't wait for child: with an $? value of 256.

If it helps, I'm running on Solaris 8.
