Forum OpenACS Q&A: Virtual Hosting using nsvhr/nsunix

Hi!

I would like to host a couple of different servers running on the same IP address, using the nsvhr/nsunix modules od AOLServer. I've read some different threads about it (like http://www.arsdigita.com/bboard/q-and-a-fetch-msg?msg_id=0009h1&topic_id=web%2fdb&topic=) and thanks to Jerry Asher (good job, by the way) and his document Multiple ACS installations with one static IP, I think I understand how it works.

I have suceed in making it work with nsvhr/nssock combination, but not with nsvhr/nsunix.

I've used aolserver-src-3.1ad8 with Jerry Asher's patch.

The relevant part of the nsd.tcl files is:

# server1 is listening on port 80, just acting as a proxy to server2
ns_section "ns/server/server1/module/nsvhr"
     ns_param Timeout      29
     ns_param Method       GET
     ns_param Method       POST
 
ns_section "ns/server/server1/module/nsvhr/maps"
     ns_param "server2"      "unix://server2"

ns_section "ns/server/server1/module/nssock"
     ns_param   port         80
     ns_param   hostname     "server1"

# server 2 is listening on port 8000
ns_section "ns/server/server2/module/nssock"
        ns_param   port         8000
        ns_param   hostname     server2

ns_section "ns/server/server2/module/nsunix"
     ns_param hostname "server2"
     ns_param port      "8000"
     ns_param socketfile "server2"

The problem arises when i start the servers. Server1 runs O.K. (i check it musing it act as a proxy, but this time with nsvhr/nssock). In the log appears:

Notice: nsvhr: redirecting: host: server2 ->
unix:modules/nsunix/server2

So the proxy part looks O.K.

The client log gives the next error when loaded:

Error: nsunix: failed to start listening: No such file or directory

So i guess the problem is with the file acting as a socket being created. I've checked that the directory ${aolserver_install_dir}/modules/nsunix exists.

When both servers are running, if i try to access server2 through the proxy (by using http://server2), the following line appears in server1's log file:

Error: nsvhr: could not connect to unix:modules/nsunix/server2:
Connection refused

My question is: what am i doing wrong? Shouldn't this socket appear in that directory after running the server?

I don't know what else to try. Any suggestion will be apreciated.

Thanks in advance!
