I've heard from several people that it's possible to do this, specifically over a socks5 proxy, and I was wondering if anyone had any definite info on whether or not this is possible. I know how to set up an SSH proxy and forward ports, but I don't know how to integrate this with Nexuiz.

I have no idea who told you this, as it is wrong. Nexuiz and about every other game uses UDP, it won't be possible to get that through a ssh proxy.

In theory, SOCKS5 supports UDP, but ssh's proxy mode (ssh -D) doesn't. No idea if any of the SOCKSifier preload libraries (tsocks, socksify for example) support UDP.

I can play Nexuiz over a SOCKS5 proxy without problems. You will need a software that wraps nexuiz to allow this. For windows XP there is FreeCap or SocksCap which can do that.

Do you know of any programs like those for linux?

of course not

but a linux freak should be able to answer this with ease

Nope, no idea. Never used SOCKS for anything serious. You may want to try tsocks or socksify.

Hello. First post here. Any ideas how to get Nexuiz working with Squid?

MrAwesome wrote:Do you know of any programs like those for linux?

I think you just set up an internal network using tun, and route that through a connection that is configured to use a proxy. I could be wrong.

No, squid is an HTTP proxy.

I know that Squid is http proxy. I've tried http tunnel (several, which were found using google) but I can't get it to work so I've decided to ask here if somebody had similar problem. Would it be possible that nexuiz servers could support http encapsulated packets directly without the need of an external server?

Certainly not. TCP is anything but good for playing games - so even if it DID work, you'd have an awfully bad connection (every single lost packet would hang the game for some seconds, for example). Really not worth it - and going over HTTP would make it even worse than just TCP.

No, because Nexuiz (just like pretty much any other game) is using UDP, while http is send via TCP.

I was thinking about smth similar to this: http://tunnel.mrq3.com/explain/node6.html and what about UDP over HTTP (e.g. http://gray-world.net/pr_firepass.shtml)? Did anyone try this?

It is not even worth trying. You will successfully go through the proxy with that, but have an AWFUL playing experience (bad and erratic ping, bad packet loss). Forget it, simply.

The best quality you can achieve for such a tunnel is probably an IP over TCP tunnel via OpenVPN. But this does not go over HTTP.

Then the only place where I can play Nexuiz is the bunker (home).
Thanks for the help, anyway.

Home sweet home.. no better place to get some frags

If you still want proxy wrapper under *nix, it's "proxychains" - worked perfectly - I couldn't beleive it worked so good at first .

Hi! I tried proxychains, tsocks and some other but nothing work. Can you say in detail how do it? Show you proxychains.conf for example.

proxychains cannot bind to an UDP port, which is required for DP (which that way reuses the same socket and local port for multiple connections). Not sure if the others sockifiers can.

Is anyone still interested in this and running Linux, or willing to install Perl on Windows (www.activestate.com)? I might write a simple UDP-over-HTTP-proxy application for you to try it out, so you can see how bad it works

The prototype:

Install Perl.

Download this script: http://emptyset.endoftheinternet.org/~r ... dp2http.pl

Open a command prompt/terminal.

Set the https_proxy environment variable:
UNIX: export https_proxy=http://your.proxy.address:8080
Windows: set https_proxy=http://your.proxy.address:8080

Run it: perl udp2http.pl 141.2.16.23:26000 127.0.0.1:26000 1

Start Nexuiz

Open the Nexuiz console

type: connect 127.0.0.1:26000

You'll end up on my Nexuiz server, tunnelled through your HTTP proxy.

Please tell me how well it works (regarding lag, packet loss). I do not expect it to work well, but if it works well enough for you, it might get turned into an option of the game (but server browsing will probably never be supported that way - you'd have to use the server browser websites and get the IPs from there).

Note: it ONLY works if your proxy allows CONNECT requests to other ports than the SSL standard port (443). Some FTP clients like FileZilla require this to work through a proxy, though, so chances are it is enabled.

Not only got error but it also killed my wireless connection. Will try again.


EDIT:

Ok, worked very nice. And I mean VERY nice. Of course zero pl , but was way better than I expected. Game is playable. Ok, some movemement distortion exists but your server load didn't help that.

Conclusion, could be an option (of course, last case solution).

The server load was due to a runaway bitlbee process

In my case it worked nevertheless... and worked really good, although, of course, serverlist was always empty and I needed to connect to IP manually. If you need my config anyway - this is it:

Code: Select all

# proxychains.conf  VER 3.1
#
#        HTTP, SOCKS4, SOCKS5 tunneling proxifier with DNS.
#   

# The option below identifies how the ProxyList is treated.
# only one option should be uncommented at time,
# otherwise the last appearing option will be accepted
#
#dynamic_chain
#
# Dynamic - Each connection will be done via chained proxies
# all proxies chained in the order as they appear in the list
# at least one proxy must be online to play in chain
# (dead proxies are skipped)
# otherwise EINTR is returned to the app
#
strict_chain
#
# Strict - Each connection will be done via chained proxies
# all proxies chained in the order as they appear in the list
# all proxies must be online to play in chain
# otherwise EINTR is returned to the app
#
#random_chain
#
# Random - Each connection will be done via random proxy
# (or proxy chain, see  chain_len) from the list.
# this option is good to test your IDS :)

# Make sense only if random_chain
#chain_len = 2

# Quiet mode (no output from library)
#quiet_mode

# Proxy DNS requests - no leak for DNS data
proxy_dns

# Some timeouts in milliseconds

The proxy in config file is working and is near Moskow.

Are you sure it actually went through the proxy?

Well, I'm definitely sure that without proxy I couldn't play over a network

Hi,
What is the feasibility of trying some sort of udp-over-ssh trick like this:
http://www.zarb.org/~gc/html/udp-in-ssh-tunneling.html
?

I tried something like this on a local network, and the client would connect to the server, but then I could never get out of spectating mode.
