Port check from server

Is it possible to test a TCP port on a remote machine with the Hobbit
server?  I have some applications that can't be tested with anything
standard (HTTP, SMTP, etc).  I'm just looking for a basic acknowledgement
that the TCP port is listening on the host being monitored.

Thanks,
Josh

Yes, if the service is listed in /etc/services.  Use the PORT test.  If it's non-standard, it can always be added.

You could do it at least two ways:
1. Have hobbit client on the remote machine check for the listening port in netstat
2. Define the port in bb-services.cfg and add the tag for the new service to your bb-hosts.

I don't see the syntax in bb-hosts, should this be done in
hobbit-clients.cfg?

I'm after that second option - though when I telnet the port I don't get any
information back, can the test still be accomplished with this?  There are
no welcome messages or anything of the sort =/

You could just add the entry to bb-services and add that entry as a
check on the servers...

Such as 


bb-services 

[wints]
  Port 3389

Then in bb-hosts

10.1.0.1 windowsbox # wints

It pretty much boils down to where you want to test.

The PORT test that I describe runs at the Hobbit client and uses the Netstat command to show that the listener is posted.  If you believe it, then all is good.

What Charles describes actually checks the connection from the Hobbit server to see if something is there.  The rub is, will something respond... :)

Doesn't matter. Unless there's an "expect FOO" then Hobbit doesn't
expect the service to return any data. What you're after is just like
the "qmtp" check in the default bb-services file:

    [qmtp]
        port 209

Just define your service like that, and you can then configure it in
bb-hosts like all the other standard network tests.


Regards,
Henrik

The way I read it, the test had to have some kind of message like that.
Sounds good, thanks a bunch Henrik!
