Each group goes into a HTML "table", and there is currently two
"<br>" tags between each table. This is not configurable, the layout
of the page is deeply embedded in the bbdisplay/pagegen.c code.
(Which is annoying, because it ought to be easy to modify the layout
of the webpages. But that's another story).
Two "<br>" tags might be a bit much. I've dropped one of them in the
next version, let me know if you think that's better.

OK, not terribly difficult to do, and it would make sense to use
regex'es throughout (you can do it with the http content checks).

I'd like to know exactly which program is crashing. I suppose it's the
bbtest-net tool which is the one that performs the "apache" test - if
it crashes, then all of your network tests should go purple. Does it
work any better if instead of the "apache" keyword you define an http
content check like this:
220.127.116.11 www.foo.com # cont=apache;http://18.104.22.168/server-status?auto;.
This should give the same result.

Yes, like this:
title All of my Web servers
group-compress Extranet servers
group-compress Intranet servers
See the description of the "title" tag in the bb-hosts(5) manpage.
>5. What rules does hobbit follow for looking up hostnames?
1) If there's a "testip" tag on the host entry in bb-hosts, it uses
the IP-address from the bb-hosts file.
2) Hostname lookup (either /etc/hosts or DNS)
3) If lookup fails, use IP-address from bb-hosts
See the description of the bbtest-net "--dns" option. This is slightly
different from Big Brother, which uses the bb-hosts IP for ping-tests,
but hostnames for TCP tests.

You can. If you want to check ssh on port 8022, put "ssh:8022" in the
bb-hosts file. bb-services just defines the default port.

OK, this is a bit more complicated because it would require bbtest-net
to merge the results of those three tests into one status-message.
That is not being done for simple TCP tests, only for http tests
currently. Right now, You'll have to set these up as individual

No, but I do have a wishlist at amazon.co.uk - just search for my
name "Henrik Stoerner" on their wishlist page.
