Re: How to disable timeout in Net::Telnet

Update 2: Ok, I just tried the following, where "dir" will hang at a "more" prompt:

use Net::Telnet ;
my $telnetSession = new Net::Telnet (Timeout => undef, Prompt => '/\>/
+') ;
$telnetSession->open("10.0.0.1") ;
$telnetSession->login("administrator", "password") ;
my @DirInfo = $telnetSession->cmd("dir") ;
[download]

The only thing changed from the code I ran is the IP and the User and pass and it is still hung (5+ minutes). This is on Win2K with ActiveState's v5.6.1 build 629.

So it looks like the desired behavior is working for me.

Update 3: Ah, it just timed out...from the other side! Are you sure it's Net::Telnet and not the responder that is timing it out? (and yes my sniffer confirmed it :)

~~I looked through the timout methods in the module, and it appears to require a numeric timout, undef is treated like you did not specify anything and hence defaults to 10 seconds.~~

My other suggestion is to crank the timout up to the max seconds you could ever imagine the data retrieval to take, add a 1 minute buffer, and use that.

I would also recomend setting the timeout right before the command and then resetting it right after.

Update: A second look tells me that undef should be valid! I'm looking into this further.

"Nothing is sure but death and taxes" I say combine the two and its death to all taxes!

Which module? Unless the doc is wrong this is what was said from the Net-Telnet 3.02. Section on timeout If $secs is 0 then time-out occurs if the data cannot be immediately read or written. Use the undefined value to turn off timing-out. However, maximizing the seconds would have been my suggestion if I saw this in time ;)	[reply]

Yes, Ok I got a bit now. It is not the Net::Telnet, its the server that is timing-out the telnet session before the process is completed.How do I over come this problem of server timing out?Any help? Thank you very much. Sridev	[reply]
