Hi ,

  I have to write a shell script to telnet to specific host and execute the admin command there. Please help me to do that.

Eg : telnet hostname portno
admin command
exit

Do you mean to execute command on telnet prompt?

You generally do it with heredoc.

telnet host port << END
LOGIN:USER:PASS
OTHER TELNET COMMANDS
quit
END

The specific host is the admin box... I have to run the script from after telneting..

Ok. So you want to execute shell commands right?

Try..

( sleep 3
 echo ${LOGIN}
 sleep 2
 echo ${PSWD}
 sleep 2
 echo "/usr/bin/ksh /some/script.ksh"
 sleep 5
 echo "exit" ) | telnet ${HOST}

You can skip/decrease "sleeps" but sometimes those are really helpful to save you.
