Cannot get enable> mode to work

[ArifS]

I have a long script that is getting stuck while handling the > (enable) mode.
I am trying to authenticate in the following two senarios-

1)
username:
password:
Device>

1st scenario- getting stuck at Device>.

2)
Device>
Same for the 2nd scenario stuck at Device>.

use warnings;
use Net::Telnet;

my $Telnet = new Net::Telnet;
my $InHandle = $Telnet->input_log("input.txt");
my $OutHandle = $Telnet->output_log("output.txt");
my $prmpt = '/[\w().-]*[\$#>:.]\s?(?:\(>\))?\s*$/';

$host="172.16.1.1";
$username = "user";
$password = "pass";
$enpwd = "enable";

my $telnet = Net::Telnet->new(
Host => $host,
Input_log => "input.log",
Output_log => "output.log",
Dump_Log => "dump.log",
Timeout => 10);

# provide host address
$telnet->open("$host");
print "\n\n Connecting to $host\n";

# authentication
@out = $telnet->waitfor('/Username: $/i') || next;
$telnet->print($username);
print "@out\n";    # for tshoot only
@out = $telnet->waitfor('/Password: $/i') || next;
$telnet->print($password);
print "@out\n";    # for tshoot only

# if enable, send "enable" and enable-pwd
unless ($telnet->waitfor('/Username: $/i' | '/#/i'))
{
#$telnet->waitfor('/>/');
@out = $telnet->print('enable');
print "@out\n";    # for tshoot only
@out = $telnet->print($enpwd);
print "@out\n";    # for tshoot only
}
print "username, password, & enable mode authentication accepted-\n";
$telnet->close;

Output:

 Connecting to 172.16.1.1
1
1
pattern match timed-out at c:\temp\dirB2D.tmp\testing 3.pl line 35

Press any key to continue . . .

 Connecting to 172.16.1.2
pattern match timed-out at c:\temp\dirEDA1.tmp\testing 3.pl line 26

Press any key to continue . . .

I get the username and password passes thru in Scenario 1 but gets stuck in enable. Scenario 2 with .1.2 it doesn't like @out = $telnet->waitfor('/Username: $/i').
Please help!

Have you read the Net::Telnet debugging advice?

In your code, you have

if ($telnet->waitfor('/#/i')) {
...

But in the example session, there is no # character. Is that maybe the problem?

I see "enable" - is this a Cisco device? Try Net::Telnet::Cisco which handles the Cisco-specific prompts and makes Telnet to Cisco devices easier than just using Net::Telnet by itself.

I am trying to avoid net::telnet::cisco, as it doesn't give all the features, and had much more luck with the net::telnet.

Anything wrong in the following format? -

# authentication
  if ($telnet->waitfor('/Username: $/i'))
  {
  $telnet->print($username);
  }

  elsif ($telnet->waitfor('/Password: $/i'))
  {
  $telnet->print($password);
  }

# Wait for the prompt, send "enable" and enable-pwd
  elsif ($telnet->waitfor('/>/'))
  {
  $telnet->print('enable');
  $telnet->waitfor('/Password: $/i');
  $telnet->print($enpwd);
  }
  else
  {
  $telnet->waitfor('/>/');
  $telnet->print('enable');
  $telnet->waitfor('/Password: $/i');
  $telnet->print($enpwd);
}

It doesn't like the format. But individually works just fine.....

Net::Telnet::Cisco subclasses Net::Telnet, so everything you have in Net::Telnet is actually available in Net::Telnet::Cisco.
