telnet package

[preethib]

Hi,

I am trying to write a script that simple executes a command on the telnet to a host and port and saves a 'result.txt' in the same directory.
-------------
Example:
-------------
test>telnet test.host.com 9999
Trying ..
Connected to test.host.com
Escape Character '^]'.
<command to execute>
{should output results}
-------------
This works fine showing results when tried to telnet and execute a command. I have a list of commands in a text file I like to execute when connected to a <host & port> on telnet.

Need help as to what packages to use and how. I have never tried this type before, but would appreciate if an expert can help.

You can find a module that will help at

http://www.cpan.org/modules/by-module/Net/.

Net-Telnet-3.02.tar.gz

If you don't want to use the module, you can simply open a pipe to 'telnet', connect to the other system, and print your commands through the pipe. Here is an example of doing that with ftp...

# Set the default values.
$cmd       = "ftp -n";  # change "ftp -n" to "cat -n" for testing.

$template  =
"      open $remote_host
       user anonymous guest\@$localhost
       ascii
       lcd \"$config_dir\"
       cd $remote_dir
       get $dblist_file 
       bye
";
print $template;

# Run the batch ftp command.
print(STDERR "      Running command ($cmd).\n");
open(CMD, "|$cmd") || die("Could not start command ($cmd). $!\n");
print CMD $template;
close(CMD);

I would suggest figuring out the module. It has been my experience that most available module on CPAN will save a lot of work in the long run.

'hope this helps...

Hi Goboating programmer,

Thanks for the reply. I am a bit confused on using login information. Since when I try to run the command on telnet I don't enter any login/passwd information. As mentioned before, I type in the command just after the line

'Connected to test.host.com
Escape Character '^]'.'

Does this mean by default I am using the same login profile of the system to telnet.

hello balji9,
I'm sorry I don't have time to get into this right now. I did, however, find a decent reference for using the Net::Telnet module on activestate.com at

http://velocity.activestate.com/docs/ActivePerl/site/lib/Net/Telnet.html.

That module is available for Linux, Solaris, and Windows from

http://www.cpan.org

or for the WinOS's from activestate using their PPM utility. Sorry I can't be of more use immediately. I have not worked with this module before and don't have the time to do any digging.

'hope this helps.
