I am writing a shell script which will accept take following parameters:
1)hostname
2)username
3)password
5)input file this contains commands to be executed on remote machine.
This script will telnet the hostname and login using username and password and then execute the commands containing in the file

Hi,

if my understanding for your question is correct then try the following :

REMOTE=hostname #or IP address
(sleep 5
echo username
sleep 5
echo password
sleep 15
echo "ls -ald /tmp" #Your command
sleep 5
echo exit) |telnet $REMOTE

This should do the trick

Thanks

Any particular reason you can't use "remsh", "rexec" or "ssh"?

See if this works with following:
echo "Enter Hostname :"
read VAR1
echo "Enter Username"
read VAR2
echo " Enter command to execute :\n"
read VAR3
remsh $VAR1 -l $VAR2 $VAR3

This will not ask you for password but verify for the username and also you need to
.rhosts files for the same.

Thought could be an simpler solution but security issue is still there.

Hello,

Look for "expect", it expect for certain reply from the remote host before issuing another order.

Ant - the java make utility - is also capable of this.

Cheers
