[Khalid Shakoor]

Hi,

Thanks in advance

With native windows telnet client you have very limited scripting possibilities.

Look "Telnet Scripting Tool":
http://www.freewareweb.com/cgi-bin/archive.cgi?download=1&ID=645

Or, if you have some Perl knowledge:

From Windows machine you can create simple BAT file and use Telnet.exe command-Line parameters. See detailed description here:

Hello,
I used with succes Tera term pro:

I managed to create a script that is making telnet to a network switch and does a enable or disable of a port. The script is called with a batch file and scheduled tasks. It works fine for me.

Hi All,


I have similar task like savus's post...

- I have list of SAN router Switches (McData Eclipse 2640)
- I need to pull some status output daily form these devices (<# show mgmt> & <# show environment>)
- I want to automate this process in to a script (through windows bacth file if possible or with someother script base)
- I expect the script to do telnet logins, and command execution and redirect the output to a file and semd email.

I'm a SAN guy... not good in scripting... trying to find the best way to do that.

Appreciate yourt suggestion & idea on this.

Hi Sathish,

I do this with a couple tools. First, I use the freeware TST10 to establish a telnet connection. The executable reads from an input textfile like this:

HOST01 23
WAIT "username"
SEND "root\m"
WAIT "passw"
SEND "mypassword\m"
WAIT ">"
SEND "show all\m"
WAIT ">"
SEND "logout\m"

TST10 dumps the output to another textfile that I specify with a switch.

I then have a free program to send mail, BLAT. Put this together in a batchfile and make it a scheduled task, I think you will have your solution.

TST10 /r:instructions.txt /o:outputfile.txt
BLAT -attacht "outputfile.txt" -s "Telnet Results" -to MyEmailAddress@MyDomain.com


Good luck!
