telnet using script

[Srikanth Vukkadala]

Hi,

I want to know how to telnet a remote Unix server using a script from Linux server
when I am using a script like this
#!/bin/bash
(echo open 10.101.1.181
sleep 1
echo root
sleep 1
echo passwd )|telnet
then I am getting error "Connection closed by foreign host"

I would change sleep 1 to sleep 2 and also check if root login is allowed on remote host or not.

Also have a look at "expect" script that helps you enter username and password.

Additionally you can also explore rsh and ssh option.

See man rsh and man ssh.

Hoope that helps.

Hi,

Expect is a solution,
Another solution is to user Net::Telnet package (look in CPAN at http://search.cpan.org/~jrogers/Net-Telnet-3.03/)

Here attached a simple example that makes use of this Telnet lib to run and printout result of a command after login is performed.
