multiple servers on one machine

[Fuddl]

hi there!

i plan to set up a bunch of nexuiz servers on a machine with a single network card for a lan-party, but i ran into some trouble:

if nexuiz servers are listening on all ip addresses/all network interfaces, they happily select different listening ports to listen for connection automatically, but only the first server which is listening on nexuiz' default server port shows up in clients' in-game server browsers.

when i apply a bunch of virtual network cards with different ip addresses and have each server bind to a separate ip address, listening on the default port, none of these nexuiz servers appear in the in-game server browsers.

is there any known workaround for at least one of the above scenarios, so that all servers on that single machine appear in the in-game browser? (i'd like to avoid setting up virtual machines ;) )

cheers - fuddl

I just set them up on different ports, 26000 - 26003 for example. I also use the dedicated server and configure it through the server.cfg -- all my servers show up on the game browser.

Not sure if that's doable with the GUI. I suspect it is. Changing the port should be all you need. No need to fool around with separate IPs or anything. I can't imagine using virtual machines for that -- imagine the load

do you have the servers register at the master server (sv_public = 1)? that would explain to me why your servers apper in the game browser. or is there perhaps a config switch i don't know about?
in my case there's no internet connection available, so the servers cannot register at the master server and clients can't ask it.

How's that supposed to work? With just one physical network interface, all servers on virtual interfaces would get a different port via nat unless i'm missing something here...

VMs would have the same problem.

If there's no internet connection available you could just run your own dpmaster.

If this is on a lan, you can setup your TCP/IP settings to give the machine multiple IP address manually, from there, launch each game with -ip 192.168.0.x (adjust accordingly) which will leave the default port at 26000 and give each server a unique IP so each will show when you go to the game browser.

The game browser does not require sv_master for lan games as I recall, it just does a subnet scan for the default port.

@KadaverJack: i don't know how it's implemented (NAT, whatever), but you can set up a bunch of ip addresses for an ethX interface. since kernel 2.6 (afaik) you can also set up a bunch of tun/tap devices and use a software bridge to stuff them together. that bridging-thing is easy to set up and works fine for two virtual machines which are connected to the LAN via bridged tun/tap devices.

@Willis:
that's what i tried, but as soon as i give the -ip XYZ arguement, that server doesn't show up in the game browser. using the connect-command from the in-game console still works to connect to the server. so i think, i must be doing something wrong...
