I don't think that is supported at all with the NT broadcaster.
ready/total are private Apache statistics. As ntbhb isn't part of
Apache, it doesn't have access to these. While I am sure it could be
modified to find and publish that information, I am fairly certain that
the existing code make no effort to do so.

Hmm... doesn't look like viewcvs is working there anymore. I have a
mirror of the mod_backhand repository on my cvs server and viewcvs is
available for it:

That is correct. Theo and I (the NT BHB developer) spoke about making the
ready/total 1/1 or 0/1 or something similar. I wanted to make it 1/1 since
NT always has 1 process available of 1 running process (when the web server
is up). However Theo thought 0/0 was better since when using IIS there
really isn't an apache process running. Theo is the subject matter expert
so I went with what he thought was best.

I definetly recommend running NTBHB as an IIS filter so that it comes up /
down with IIS. If your using Apache on NT, run NTBHB as a service (so it
comes up / down with the machine).

Good luck
Rob

Sounds like the moderator is running but the unix socket directory is
set with the wrong permissions.

This makes sense now. Sorry for being confused.

I'm now having an unrelated problem. I seem to be able to successfully
HTTPRedirect (by IP and name) from the moderator to another unix or NT
machine, but I'm not able to proxy! How is this possible?

I get the following from error_log:
-------------
[notice] (Type =>) = *{ backhand-redirection,
backhand:backhand:backhand:/test.html, (null), (null) }
[error] mod_backhand: MBCSP error(recv file descriptor)
-------------

Backhand starts over after this error and executes (successfully) all of the
candidacy functions and then errors again. After a few of these errors, the
[notice] line gets an additional "backhand:backhand:". This continues until
I stop apache, with big error_log resulting.

Another quirky thing is on the HTTPRedirect, sometimes the browser address
doesn't change to reflect the redirect, but the page content is definitely
what should be displayed and I get the following in the log:
-------------
[error] HTTP Redirection by IP [2]
-------------
That's all the log gives me. Is this really an error or just an occasional
nuisance?

I set the UnixSocketDir permissions to 777 (just to prove it's not a
permissions issue) and I get the same error.
I know that the arriba file is put into this directory, but what else should
be there?

Here's what I see:
drwxrwxrwx 12 ownername groupname 96 Jul 23 14:56 .
-rw-r----- 1 ownername groupname 0 Jul 23 14:56 bparent
-rw------- 1 ownername groupname 6 Jul 23 14:55 mod_backhand-Arriba

Mine looks like this:

-rw------- 1 root root 6 Aug 6 2001 mod_backhand-Arriba
srwxr-xr-x 1 nobody nobody 0 Jul 17 10:28 bparent
srwx------ 1 nobody nobody 0 Aug 29 2001 bchild-21245

followed by many many more bchild sockets -- they are of the form bchild-PID

Okay, maybe this sheads light on my problem. I don't see any bchild sockets
in the directory. What could cause these from not being created?
