When Net::Telnet doesn't do what you expect, 99% of the time it's a prompt issue. Did you set the prompt? The default prompt works with the unix command line, but you'll have to set it to work with your application.

Re: Net::Telnet::Cisco script not waiting for prompt
Hi Howard,
I have some experience in writing scripts with this excellent module,
some of which have been used on c2500 routers.
Sometimes, I find that setting the terminal length to zero at the start
of the script can help:
@output=$RSession-cmd(String = 'term length 0', Timeout = '3');
(you need enable mode before sending this command)
Experiment with this, but if all else fails, you could get in touch with
the module author via his web forum:
http://nettelnetcisco.sourceforge.net/
HTH,
James.

RE: Net::Telnet and Term Type
Normally, that cmd would do the trick. Unfortunately, my script needs to connect to a login without shell access, so I cant set TERM that way on the remote (UNIX) box. The login is given a menu from the start, and it is from that menu that I call the program that wants to see vt100. The local side is a WinXP box. Setting TERM in the local XP-DOS environment did what I expected: nothing. Any other ideas? [So far, the only choice Im seeing is to work-around by inserting an extra hopconnecting to a UNIX shell login first, using that cmd(export TERM=vt100) there, and then re-connecting from that shell login to my destinationbut that is definitely not a preferred way to do this. It would be much better to go direct if there is a way.] -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mingbo_Wan Try tm-cmd(export TERM=vt100) -- I need to set the Telnet terminal type option for a telnet connection using Net::Telnet.

Ive tried looking through the docs and Telnet.pm, but Im not sure how to go about using TELOPT_TTYPE, or even if that is what I need to use.
Re: Net::Telnet on Win2K
John, The problem is outlined in the Net:Telnet documentation. The loads of gibberish is ANSI terminal escape characters. I haven't worked with that exact telnet application, but some allow you to turn ANSI off and on http://search.cpan.org/author/JROGERS/Net-Telnet-3.03/lib/Net/Telnet.pm Connecting to a Remote MS-Windows Machine By default MS-Windows doesn't come with a TELNET server. However third party TELNET servers are available. Unfortunately many of these servers falsely claim to be a TELNET server. This is especially true of the so-called Microsoft Telnet Server that comes installed with some newer versions MS-Windows. When a TELNET server first accepts a connection, it must use the ASCII control characters carriage-return and line-feed to start a new line (see RFC854). A server like the Microsoft Telnet Server that doesn't do this, isn't a TELNET server. These servers send ANSI terminal escape sequences to position to a column on a subsequent line and to even position while writing characters that are adjacent to each other. Worse, when sending output these servers resend previously sent command output in a misguided attempt to display an entire terminal screen. Connecting Net::Telnet to one of these false TELNET servers makes your job of parsing command output very difficult. It's better to replace a false TELNET server with a real TELNET server.

RE: Net::Telnet on Win2K
Yah, yahread all that. Question is, how do you stop the Win2K telnet server from defaulting to an ANSI terminal? This is particularly worrisome as the option_send method has not yet been written for the Net::Telnet module so it is impossible to ask the Win2K server to change from inside the perl app. I have tired the following unsuccessfully: 1. Reordered the terminal parameters setting on the Win2K telnet server box in the c:\winnt\system32\termcap file (this was an attempted hack as I know nothing about termcap files), 2. Renamed the termcap file to that tlntsvr couldn't find it which causes tlntsvr to exit after login, 3. Used the /y switch in the console execution entry in the registry. At this stage of the game, I am going to give up since the option_send method is not up yet. Since my app simply requires me to identify whether a remote perl script executed successfully on the target Win2K machine, I can search through the gibberish with regex and check. Unfortunately, this does not solve the more general issue regarding the tlntsvr on a Win2K box. Mickeysoft has ZERO information on the termcap file anywhere on their website but it appears to follow the Unix syntax. They also have ZERO information on how to change the default terminal setting for the tlntsvr. Anyhow, That's it for me on this issue.

RE: NET::Telnet
Greetings,
I too had alot of trouble getting Net::Telnet to work properly,
it seemed to continuously stop for no apparent reason, with very
poor performance. As well as not being able to make it non-block
on win32.
I had to eventually write a direct TCP client to get a proper
level of performance..etc..
Just my .02,
-Lenny

Carter, what you're saying may work on Unix systems, but after 2 weeks of
hair-pulling last year, I gave up trying to use Net::Telnet on legacy Univac
and Dec systems. The module just couldn't handle the odd terminal emulation
escape sequences that were being fed to it (especially on the Univac) and I
was unable to reliably establish and maintain terminal sessions on those
machines. Finally had to brute force ftp files up to those boxes without
being able to do the file existence/status checking planned for in my
original design. Net::Telnet users beware.

The Prompt is a regular expression that matches the
commandline prompt from the remote shell. That means
you'll want to match the prompt for the user you are
logging in as. If I log into one of my remote windows
machines through a telnet server and I see I have a
prompt like so, C:/ I'll need to match that within
my code as prompt.
If the prompt isn't matched in the time specified in
Timeout then the script will either return false or
die based on what Errmode is set to, return or die respectively.
NET::Telnet Defaults:
Timeout = 10
Host = localhost
Errmode = die
Prompt = /[\$%#]$/ # matches most unix shells.
Port = 23
This is how you could establish a connection with a
windows machine with NET::Telnet (Untested).
use strict;
my $TIMEOUT = 30;
my $PROMPT = C:/;
my $HOST = foobar.foo.com;
my $USER = Bob;
my $PASS = password;
$telnet = Net::Telnet-new( Timeout = $TIMEOUT,
Prompt = $PROMPT,
Host= $HOST,
Errmode = return);
$telnet-login($USER, $PASS);
# Test here for success if using return.
my $msg = $telnet-errmsg();
if ($msg) {
print $msg\n;
$telnet-close;
# do whatever you want here.
}
Hope this helps.
Cheers,
Carter.

RE: NET::Telnet
First, if you are telnetting from a non Windoze PC, you must turn off NTLM
authentication on the host.
This works on an NT box:
use Net::Telnet;
use strict;
use warnings;
my $telnet = new Net::Telnet ( Timeout=10, Errmode='die');
my @jim=;
my $frank=;
$telnet-open('192.168.174.108');
$telnet-waitfor('/Username: $/i');
$telnet-print('Administrator');
$telnet-waitfor('/Password: $/i');
$telnet-print('12345');
$telnet-waitfor('/\$/i');
$telnet-print('show users');
@jim=$telnet-waitfor('/\$/');
Its similar for W2K except that Username is login.

Jitranda,
I gave up trying to figure out what to use as a prompt for
Net::Telnet when
connecting to Windows' telnet server.
Maybe someone out there will enlighten us both.

Re: net::telnet
I have no familiarity with the Net::Telnet module, but I believe the SU
syntax is
actually 'SU -' to open a shell that you can log into.

su should require a password so normal users cannot
arbitrarly becomeroot.
