Thanks, Ralph.  I'll keep this in mind.

Have you considered "expect"??  It's an extension to Tcl that can spawn
a program, such as telnet, and then send commands to it.  I have a
script that telnets to a given server, answers TACACS prompt if
necessary, and logs in, then su's to root - if the password is provided.


You should be able to spawn a telnet command to a specific IP + port
number, just as you would on the command line.  Send the AT command,
wait for the response.  If it times out, do one thing, if the response
occurs, do another thing.  Lather, rinse, repeat. 

I haven't yet got into running much stuff via Hobbit, but I've had a lot
of success over the last 5 years firing off Big Brother scripts from
cron.

I've been using Big Brother for about 4 years and have been testing
Hobbit and plan to switch over soon.  I have a situation that I have
never been able to figure out how to address, so I'd like to throw it
out here and see if anyone has any ideas.

 

We have a terminal server with 7 fax modems connected to it.  A Unix
server uses it to fax reports out to various doctor's offices around
town.  For reasons that we've never been able to figure out, one or more
of the modems will occasionally "lock-up", i.e. quit responding to
commands.  This usually locks the associated serial port on the terminal
server as well.

 

I would like to be able to monitor these modems by connecting to their
port on the terminal server, i.e. 192.168.1.15:2001, send them an "AT"
command, wait a few seconds for a response, then disconnect.  I can't
figure out a way to connect to them with the additional requirement of
having to use the network port that they addressed by on the terminal
server...in this case, 2001 through 2007.

 

Any help would be greatly appreciated.

 

And , by the way, I think Hobbit is great!  I think it is a big
improvement upon Big Brother, although I must admit that we're on the
"better than free" license since we are a non-profit, so I haven't seen
what Quest may have done with it.

 

Thanks in advance!
