This is sort of a follow up on the old mod_rendezvous article I wrote for O’Reilly. While cleaning up my virtual hosts I discovered a bug in 10.5’s handling of multiple RegisterResource directives in mod_bonjour. This is expanded from a bug report I submitted to Apple (rdar://problem/5628484).
I keep functional mirrors all my development sites in separate Apache Virtual Hosts. Each one then gets it’s own port, which allows me to check them on local networks, in Parallels and, if I want, remotely via IP address.
To advertise two local vhosts over bonjour, something like this in httpd.conf should work:
<IfModule bonjour_module> RegisterResource "Site 1" / 9001 RegisterResource "Site 2" / 9002 </IfModule>
After restarting Apache (
sudo apachectl graceful), local copies of Safari should see the two sites, “Site 1″ and “Site 2″ in Bonjour bookmark listings. In 10.4, they show up. In 10.5, only “Site 2″ shows up. No matter how many directives are included, only the last one will be visible.
I’d love to be wrong about this, but it seems that something broke this function in Leopard.
A faster way of checking Bonjour entries is to open a terminal window and run the following command:
mdns -B _http._tcp
That will show a live updating list of current multicast (Bonjour) entries. Under 10.4, I get the following after adding the above directives to httpd.conf:
16:10:14.517 Add 0 local. _http._tcp. Site 1 16:10:14.667 Add 0 local. _http._tcp. Site 2
However with 10.5, I get this:
16:12:52.597 Add 1 local. _http._tcp. Site 2 16:12:52.598 Add 1 local. _http._tcp. Site 2 16:12:52.598 Add 0 local. _http._tcp. Site 2
What I’d really love to do is figure out how to register and respond to multiple Bonjour names. That way I could have each vhost be a named host and each staged site accessible at a url like site1.local and site2.local. So far I haven’t had any luck getting that working.
