Dear All
I need to schedule for a repeated task on my Debian server, as the
followings:
-) Telnet to a remote node
-) Issue a command
-) Capture the output in a log
-) Logout from Telnet
-) Wait for a prescribed time interval
-) Then redo , but append the subsequent output in just on file
Can you please let me know which options do we have to write such a
task?
Thank you

Hello,

For that task, you want expect.
To schedule it, you need cron.

Regards.

Yes, expect will work, but if you can use ssh, use it, it will be easier.
Setup ssh to use RSA key for authentication, so it won't prompt for a
password. Then just execute "ssh username@xxxxxxxxxxxxx somecommand" and it
will run "somecommand" and the output will be sent back to you.
