Help with Net::Telnet module
I am looking for some help debugging a problem with the Net::Telnet module
written by Jay Rogers.
Here's the subroutine I am having problems with:
sub login
{
$errmode = 'return';
$hostaddress = 'xxx.xxx.xxx.xxx';
$prompt = '/Sheldon_NS16>/';
$username = 'xxxxxxxx';
$password = 'xxxxxxxx';
$obj = new Net::Telnet ( Host => $hostaddress,
Errmode => $errmode,
Prompt => $prompt,
Timeout => 15,
Port => 23 );
$obj->login($username, $password); # line 212
$errmsg = $obj->errmsg;
print STDOUT "Error - $errmsg\n" unless ($errmsg eq "");
}
This subroutine is part of a larger script (sheldon.pl) that calls this
subroutine once per minute
to login to a modem pool to get user information and log it for tracking
users usage.
The program will run for 1-2 days before dying. The error I get is as
follows:
Can't call method "login" on undefined value at ./sheldon line 212.
As I said above, the script will run for a day or two collecting data
without any problems, then
die with the error above. Any Perls of wisdom out there?
Thanks,
Sean Johnson

I don't know anything about Net::Telnet, but I'd say the call to
Net::Telnet::new is failing for some reason. You're not checking the return
value from new(). Perhaps there is a way to do that?
