A ksh script to connect to telnet automatically?

bijit1709 · 04-11-2007, 05:00 PM

How can I create a script so I can connect to a server using telnet and ssh? This is what I made but its says "Connection closed by foreign host."

#!/bin/ksh

telnet $host <<- EOF

user $users $pass

EOF

Thanks for any help!!

It is much easier to use ssh than telnet, if you use host-based authentication. To use telnet, you need 'expect'.

telnet should be avoided, it is a security risk. Use ssh, and set up public key authentication if you require passwordless logins. Once this is done, you can easily do things like this from a shell script:

Code:

ssh otherhost /home/me/bin/execute_program

to remote-execute a command on the remote host.

Thanks for the advice regarding the telnet..I already removed it and now using ssh. Thanks for the quick posts this was my first post. And never thought I would get a quick reply.

Does any one has manuals for linux, unix, ksh, c, or any other Unix related stuff please send it to bijit1709@gmail.com it will be highly appreciated.
