How To Automate A Telnet Session Without SendKeys

Question

I would like to telnet into my router, and I want to automate it so I do not have to login all the time, as I do it several times a day.

Is there another method apart from sendkeys in VBS? This is because that physically types, so the telnet window needs to be active, with is rather annoying.

I tried a batch file, but I am getting really strange results. Here it is:

telnet 192.168.1.254
REM This is the router IP
ping 255.255.255.255 -n 1 -w 1000 > nul
REM This is to wait for the router if its being slow
George 
REM This is the username, as it prompts as soon as it logs in
ping 255.255.255.255 -n 1 -w 1000 > nul
(the password)
ping 255.255.255.255 -n 1 -w 1000 > nul
system
REM Enters the system menu
ping 255.255.255.255 -n 1 -w 10 > nul
debug
REM Enters the Debug menu
ping 255.255.255.255 -n 1 -w 100 > nul
:s
 cpu
 REM This lets me see the CPU usage
 ping 255.255.255.255 -n 1 -w 1000 > nul
 REM Wait while it lists it
 mem
 REM Checks the memory 
 ping 255.255.255.255 -n 1 -w 1000 > nul
 REM Waits again!
goto s
REM I need a loop otherwise I would have to type out lots of code!

Here are the results:

C:\Users\George\Desktop>telnet 192.168.1.254

C:\Users\George\Desktop>telnet 192.168.1.254
^C Terminate batch job (Y/N)?

Why is it doing this? This would be my expected result...

Username : George
Password : *******

So, Why is it doing this?

Can I use another method apart from sendkeys?

Answer 1

You can google for this tool: it doesn't script windows telnet.exe but it is a scriptable telnet client.

Telnet Scripting Tool v.1.0

Answer 2

One way is to use some of windows versions of netcat.Here'a an example: http://net.tutscity.com/networking/automate-telnet-session-using-netcat/

Answer 3

Telnet Scripting tool (TST10) is old but yet very efficient,
here is a modern alternative to it, with a nice GUI AutoTelnet.
