In the mediaproxy there's a nice README describing this. I'll try to make a short summary: SER machine: you have to set mediaproxy to act as a dispatcher for the domain name you want to use as the "mediaproxies domain". The mediaproxy.ini should be something like: [Dispatcher] start = yes socket = /var/run/proxydispatcher.sock group = ser defaultProxy = domain://somecompany.com [MediaProxy] start=no This would instruct the mediaproxy dispatcher colocated to the SER instance to make DNS queries for the domain somecompany.com. Next step is to configure DNS server to provide somecompany.com SRV queries (next lines should be included in zone file describing somecompany.com): _mediaproxy._tcp IN SRV 0 25 25060 mediamachine1 _mediaproxy._tcp IN SRV 0 25 25060 mediamachine2 _mediaproxy._tcp IN SRV 0 50 25060 mediamachine3 _mediaproxy._tcp IN SRV 10 50 25060 mediamachine11 _mediaproxy._tcp IN SRV 10 50 25060 mediamachine12 ;INSERT the IPs of every mediamachine mediamachine1 IN A 192.168.1.1 mediamachine2 IN A 192.168.1.2 mediamachine3 IN A 192.168.1.3 mediamachine11 IN A 192.168.1.11 mediamachine12 IN A 192.168.1.12 Last thing is to configure mediaproxy.ini in the mediamachines to accept mediaproxy queries from the SER machine and to start mediaproxy: [Dispatcher] start = no [MediaProxy] start=yes allow=whateveryouthingyoushouldpoutinhere Hope it helps, Samuel. 2006/5/1, Dejan Kovacevic <dejan.kovacevic(a)volja.net>et>:
