Also tried using expect but some mistake i am making

Code:

$ cat script.sh
#!/usr/bin/expect

expect "Select a terminal"

send "18"

sleep5
send "login:uid=inventory"
sleep 5
send "flask1234!"
sleep 5
send "rtrv-stp"
sleep 50
send ""
sleep 10
send "quit"
$

Output i get

Code:

$ ssh -N -f -L 50003:127.0.0.1:23 10.64.246.124; telnet 127.0.0.1 50003 <script.sh  >>out.log
$ Connection to 10.64.246.124 closed by remote host.

Code:

$ cat out.log
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.

telnet> "
?Invalid command
telnet> Connection closed.
$

Try just putting the following text in file.txt:

Code:

18
login:uid=inventory
whateverYourPasswordIs
strv-stp

quit

In other words, just put the exact text that you would type into your terminal in response to the prompts issued by the remote server. No echo, no double-quotes, no sleep unless you would type those commands to the remote server when you are running an interactive session with that server.

And, then run your command:

Code:

$ ssh -N -f -L 50003:127.0.0.1:23 10.64.246.124; telnet 127.0.0.1 50003 <file.txt  >out.log

If you really want to preserve the output from previous runs and just tack the output from this run to the end of the output from previous runs, change the >out.log at the end of the script back to >>out.log.
