Unable to close telnet session from script

Hello people, I am creating a script that will alert me in an ftp or telnet account on my system expires. FTP part is ok, but when I am entering the 3 script, it stucks. I can see that the script will not close the telnet seession. Can you please check and let me know what I am doing wrong? What if I send a CTRL-C in the script, will it work for the telnet sessin?

Anyone ?

Replace "close" with "exit" and it should work, given that no errors while occur.

After the open command, which is processed by telnet, you are connected to the remote computer. You send username and password which should bring you to a shell, which can be closed by the "exit" command.

I tried exit close quit
Same result

Can you post the complete output of what happens when you call your script? Something seems to go wrong during connect or login.

See what's happenning if I ran telent script only:

grx666 gpd /home/bill3/scripts:./bill3_check.sh
telnet> Trying...
Connected to 10.0.0.1.
Escape character is '^]'.
Local flow control on
Telnet TERMINAL-SPEED option ON

Ah, I think I found the source of the problem:

resize: unknown character, exiting.

Your login script runs the "resize" command. It finds out the terminal's geometry by sending an escape sequence to the terminal and parsing the response. Instead of the response it reads the "exit" command, which is not understood by "resize".

Can you comment out the resize command and try again?

I ll do that as soon as I found what the resize does. (It's a prod system).

Thanks for your help !

Is there any way to to use this script and leave the resize in my .profile?

How can I send a CTRL-D inside the script ?

You can send a Ctrl-D with

printf "\4"

If you can't remove the resize command, you have to send some fake input to it. Try to start with

...
echo xxx
sleep 2
printf "\4" ) | telnet
