[gentoo-user] UDP traffic?

[gentoo-user] UDP traffic?

[Mark Knecht]

Hi,
   I was setting up a game for my son using Cedega. The game
installed, and successfully went to the net to download and install
the updates. However, when we tried to get the Linux game to join a
LAN session with the same game running on some Windows machines I got
a message about not having a network provider. Since it can get to the
Internet to download the updates I know it's not a hard networking
failure. What is it?

   In the past I've heard that some of these games use UDP instead of
TCP. I was wondering where I configure a Gentoo machine to allow UDP
traffic, preferably only on my local network if possible so that I
could just see if this was the problem.

   Thanks for any pointers you can provide.

Cheers,
Mark

What is the game? I think that's the most important information you could give.

I don't think Gentoo default network config block anything. Its more
likely to be blocked at a router or windows firewall (at your server
machine).

As long as you don't have a firewall running, UDP is enabled. In case you do 
run a firewall, that is the place to allow UDP on the used ports.

Sorry. The game is StarCraft with the add-on BroodWar.

Thanks. I'll try to check it out. However the 4 Windows machines all
connect to the LAN game just fine - 1 server and 3 clients - so any
Firewall on the server is not hindering them - only the Linux/Cedega
box.

Note that the server, one Windows client and the Linux box that will
not connect are all hard wired to the wireless router. Two other
windows clients are on a local switch in my office and then running
across a wireless connection to the wireless router.

I'll do some Googling on the exact error message and see if I can
figure out anything that way.

Thanks for the info!

Cheers,
Mark

tcpdump or ethereal will allow you to see what is happening on the
network before the error message appears.

ethereal was renamed to wireshark in portage recently to conform to 
upstream. I'd probably start with tcpdump as it's less powerful and 
you're more concerned with knowing where the packets are going than the 
specifics of what is inside them.

Mark, I run BroodWar on my Gentoo laptop and it runs like greased magic.

I will however say that if the _game_ connected to the net to get the
update (that is to say, through the battle.net interface), then it's
probably incorrectly patched.  Using the in-game updater has been known
to break the game on linux.  You might try reinstalling the game and
getting the update from the website instead.  This worked for me.

I use the game to play online games, but I haven't used the LAN function
of it to play on my local network, so this is a shot in the dark.  You
might however, try starting Samba, in case it uses it for name
resolution or something.

Also, when you go to the multiplayer menu, are you clicking "LAN (IPX)"
or "LAN (UDP)."  You want to make sure you use the same one on your
linux and your windows machines.  If one doesn't work, try the other.
You may need to enable IPX support or something, but I really don't know
much about IPX on Linux.

You need IPX support in your kernel (CONFIG_IPX) and net-misc/ipx-utils. 
  UDP in Starcraft works fine for me, however, although this is with 
regular Wine rather than Cedega.  Try running from a console rather than 
using the Cedega GUI, and see if you get any error messages.

Thanks guys! Turns out it was user error as much as anything. My son
was setting up the Windows server using Broodwar and UDP. I was
running, at the time, an install from the Broodwar CD for the Linux
box. That install showed only IPX as an option for joining so it
didn't work, as expected. Once I went to BattleNet to get an update
for Broodwar UDP became and option, I joined the Windows server and
most everything is running fine. I am having some problems with parts
of the audio coming through as static, but the game itself plays great
so far.

We also tried it the other way around with the Linux box being the
server and letting Windows clients join. That seems to work fine also.

Thanks alot for the info. Very helpful.

Cheers,
Mark
