Connecting telnet users from shell script

[Shailesh Joshi]

Hello,

I want to write a shell script, which will test some unix user-ids. The user-ids could be either ftp ids or telnet ids. Testing for FTP-ids is easy. But for telnet ids, how should I connect to those users through script so that it will not prompt for passwords. I have user-id/pwds for all the users. All the users are present on the same machine and the script will also run from the same machine.

Does anybody know how to achieve this?

Thanks,
Shailesh

Looks like a job for expect:

This will let you talk to the tty in script fashion...

Hi Gabriele,

The solution worked perfectly. In the script you have given different sleep times. Is that time fixed? And if yes, how did you arrive to those timings?

Thanks a lot for the help.

Thanks,
Shailesh

Hi Duncan and Navjeet,

I tried the binary given by Duncan, but it didn't work. Actually I am working on a Solaris machine. Will that binary run on Solaris also? Being a new member I was not sure, whether I could post questions about Solaris on this list? So didn't mention about it.

Anyway, Thanks for ur help.

Thanks,
Shailesh

Hi Shailesh the sleep time depend of the duration of the command. If you want to excute a command in a telnet script, you must launch it before in a shell, es:
# time
at the end of the output you read:
real 0.0
user 0.0
sys 0.0
You add the 3 times and you have the time for the sleep. You can add some seconds to the results.

Shailesh,

Sorry, absolutely no way that a HP-UX binary is going to run on Solaris, or vice-versa - never have, never will!

Of course you can get expect binaries for Solaris. The equivalent site for Solaris users is:

http://www.sunfreeware.com/

You'll find expect here somewhere - make sure you download the correct version for your release of Solaris.

Hello/Ciao Gabrielle,

I need to capture the system time in the log file before the ftp and after the ftp.

Also, the time before and after the remote telnet.

How can I do this?
