Re: Net::Telnet and telnet command output

in reply to Net::Telnet and telnet command output

There are three ways, all of which are documented in the perldocs for Net::Telnet. The first is to just grab the return values from the cmd method:

use Net::Telnet (); $t = new Net::Telnet (Timeout => 10, Prompt => '/bash\$ $/'); $t->open("sparky"); $t->login($username, $passwd); @lines = $t->cmd("who"); print @lines;

The second is to grab the raw input from the telnet stream (not recommended) that has already arrived:

$ref = $obj->buffer;

The third is to go and grab new raw data on its way in:

$data = $obj->get([Binmode => $mode,] [Errmode => $errmode,] [Telnetmode => $mode,] [Timeout => $secs,]);

The getline and getlines methods are probably much easier to deal with than get, and work on the same principles.

I highly recommend reading the perldoc info on Net::Telnet very thoroughly, even though it is rather tedious. I learn something every time I read it. I also recommend using the debugging/logging methods for a while. I have found them to be invaluable when trying to figure out why my patterns are(n't) matching some weird binary input. (The buffer_empty method is your friend.)

Hope that helps!

    The problem is that neither solution works.
    I've tried all of them already.
    That's why I asked here.
    Is there anything else I can try?
    I guess the problem is that the switch doesn't act like
    the regular operating system

      Perhaps if you showed us your current script and explained what it was doing wrong we could help better.
