shell script for telnet

[Yiyi]

I used following script:

telnet <IPAddress> <<!
<username>
<password>
!

And I got &quot;Connection closed by foreign host.&quot;

Can anyone explain me why?

Appreciate for your help

You can't use telnet that way. Why do you need to do this? Do you need to run a command on the remote machine? If so, have a look at the rsh threads in the General Unix Discussion/Solaris forums.

check out the perl telnet module, otherwise you could use expect to automate the telnet session. But perl is the way to go

Why not ammend your script to use rlogin <server name>

Work a treat!!!

Because the remote host might not trusted host, even running on different OS, so I have to use telnet. And I have done that with expect.


Thanks for your valuable advice!

There's another way to communicate between the server and the client.
You can use socket communication with perl, and if you want to execute something, you can combine it with Shell script.
But I still have a problem with executing from shell script. Somehow it keeps gave me memory fault (core dump) when I tried to call C program from shell script.
Could anyone tell me how to run C program including pass the variables from Perl?
Thanks.
