I was able to set up a batch file to open a telnet session, but I still have to type in my username and password for the session to actually start. Is there any way to set up the batch file to automatically enter my username and password?

In other words, I want to login automatically without typing the username and password everytime. (Like loginng in a router via telnet automatically)

telnet [-a][-e escape char][-f log file][-l user][-t term][host [port]]
-a Attempt automatic logon. Same as -l option except uses
the currently logged on user's name.
-e Escape character to enter telnet client prompt.
-f File name for client side logging
-l Specifies the user name to log in with on the remote system.
Requires that the remote system support the TELNET ENVIRON option.
-t Specifies terminal type.
Supported term types are vt100, vt52, ansi and vtnt only.
host Specifies the hostname or IP address of the remote computer
to connect to.
port Specifies a port number or service name.

Those are the commands for a telnet session - from what it says basically you should be able to use -a or -l to automatically log in - provided the server supports the "TELNET ENVIRON" option - hope this helps :)

:rolleyes:

Thanx a lot for your reply!!!!!!!

I tried it several times but couldnot be able to get through. Whether I enter the username/password in the bat file or not, it's same I have to enter the username and password everytime whenever i login.

Can someone give me a sample telnet batch file?

Manual attempt (at command prompt):

C:\>telnet XX.XX.XX.XX [enter]

after pressing enter it ask for the username (The command prompt windows clears and the Username appear at the top left corner of the command prompt windows, it seems to be a new window only with "Username:" text)

Username: XXXXXX

After entering the Username, it ask for password

Password: XXXXXX

After entering the password the router's info homepage is displayed

==========================================

Router
Version: XXXXXXXX
Model: XXXXXXXX


==========================================
=>

--------------------------------------------------
This is my sample session.

Batch file which i used earlier:

@echo off

Start C:\windows\system32\telnet XX.XX.XX.XX

===================================

I also tried the -l and -a option but it doesn't worked.


Can someone guide me in the right direction?

Thanks in advance.

As far as i can see from the doco that i have read.

There isnt anything that can automate the password section? - Correct me if im wrong people...

Basically, -a will log you will pass your current username...

I.E
telnet www.blahblahblah.com -a

Should pass your username, not a password

Whereas
telnet www.blahblahblah.com -l Admin

Should pass the username "admin" and again no password.
As far as i can see there isnt much in the way of passing a Password.

Sorry i couldnt be of more help.

here you go, copy this text to notepad and save this file to .vbs

Set cloner = CreateObject("WScript.Shell")
cloner.run"cmd"
WScript.Sleep 500

cloner.SendKeys"telnet 0.0.0.0"
cloner.SendKeys("{Enter}")
WScript.Sleep 500

cloner.SendKeys"username here"
cloner.SendKeys("{Enter}")
WScript.Sleep 500

cloner.SendKeys"password here"
cloner.SendKeys("{Enter}")
WScript.Sleep 500

cloner.SendKeys"exit"
cloner.SendKeys("{Enter}")
WScript.Sleep 300

cloner.SendKeys"exit"
cloner.SendKeys("{Enter}")

You could also use Expect or Empty for interactive scripting.
