Right ... here's what I've done then.

1. Edited/saved TCPPing.pm as above [adding the debug line].

2. Killed speedy_backend.

3. Restarted smokeping. [I know that shouldn't be necessary, but it logs 
the restart in the messages file, so it makes an easy bookmark to see 
where the changes have kicked in.]

4. Run smokeping --debug

Now ... this is where it gets a little bit weird.

I'm still not seeing anything from the TCPPing probe in 
/var/log/messages ... but I *DO* see it in the smokeping debug screen, 
and I most certainly wasn't getting that before this most recent change!

So ... where do we now stand after all of that then?
