Hi Jacques,

Actually I would have been trying it originally on a 2.4.18 + ctx-10. Now
that time has past I'm unsure exactly what led me to force the localhosts
all to local vserver IP, but I certainly remember it fixed it ;). I think
the problem was always showing itself when you used the web interface to
add a printer. It would appear to stall, and I seemed to remember it was
(according to strace maybe) to be trying to do something using
and getting an error something like permission denied.

So I thought I would just setup the obvious settings in the code to be the
local IP instead of That's when I also noticed it was hardcoded
in quite a few places in hex, and after altering them, it worked.

Now chances are you'll be able to do a default CUPS install and not have
the same problem :(. I'm currently running ctx-10 on 2.4.19-pre8, and I
could probably bring it up and see if it shows up again if you can not see
it on your end.
