	Ghita M: socks proxy scalability 04.02.2012 12:50:43
	Just installed socks on my windows machine and saw that it creates lots of threads when browsing. It seems to me 3proxy approaches it as a thread/connection design...

Ghita M: Authentication using socks4 30.01.2012 23:18:20

Hi

I am a developer and need for my application to provide authentication for socks4 clients (socks5 is not supported by IE that's why I'm stuck with ver 4, as I don't want to add additional software on clients). I need this in order to do filtering (mostly web) based on Active Directory user information on Windows. I saw on documentation that you mention to have authentication implemented for this purpose. What do you use ? Is it possible to have something general that works with many protocols like http, ftp.. ?

		3APA3A: Re: Authentication using socks4 02.02.2012 3:21:41
		SOCKSv4 doesn't support authentication. The only information SOCKSv4 client sends is username. The solution is to use some additional authentication, e.g. 3proxy can try to resolve username via NetBIOS (if messenger service is running) or resolve IP address to hostname and authenticate host instead of user.

			Ghita M: Re: Authentication using socks4 02.02.2012 21:49:35
			"3proxy can try to resolve username via NetBIOS" Do you mean here that in case the username is sent by the client as part of socks protocol you can resolve it via NetBios. Is there a way to "force" the client to send that username ? IE sends it as I saw only when you are part of an AD domain..

	kulik: SOCKS and UDP 01.02.2012 23:34:38
	Is the SOCKS proxy intended to support UDP? I can't seem to get this type of traffic through it.

		3APA3A: Re: SOCKS and UDP 02.02.2012 3:23:58
		Yes, 3proxy supports UDP via SOCKSv5. Make sure you use latest version and make sure you have exernal address configured, because it's required for UDP support. Also, make sure client applications supports UDP.

maxkau: 3proxy 'external' IP address to load balance or backup on connections 25.01.2012 21:26:49

I successfully use 2 external IPs (2 different connections) to use the first connection and, in case of problems, use the second.
I'd like to use both external IP addresses at the same time (one connection on the first and another on the second) to do something like load balancing on the 2 connections.
It could be nice if this feature could be added to 3proxy to choose to operate in the first way (backup connection) or to alternate external IP addresses on outgoing connections to do the load balancing. :)

		3APA3A: Re: 3proxy 'external' IP address to load balance or backup on connections 30.01.2012 4:11:28
		It does, see http://3proxy.ru/howtoe.asp#ROUNDROBIN

	Eduardo: plugin 22.01.2012 3:35:41
	Hi, I have to implement a socks5 server that uses a different outgoing (external, like the -e parameter) ip address for each username connected. For accomplishing that, I was planning to write a filter plugin, which would rewrite the socket data connection, but reverse engineering the code, so far, didn't provide me the answer if it's feasible or not. Could someone help me on that? ... full text

		3APA3A: Re: plugin 30.01.2012 3:14:38
		There is no need to make a plugin, you can achieve same results with 3proxy ACLs + parent command. Parent with 0 port sets the address of external interface. E.g. allow user1 ... full text

			3APA3A: Re: User Account 19.01.2012 2:57:38
			You can have users $"path_to_passwd_file" in main config and passwd file in the form of user1:CL:pass1 user2:CL:pass2 etc.

		3APA3A: Re: use 3proxy on ipad for socks 02.01.2012 2:16:03
		Run 3proxy on your iPhone with configuration like allow * parent 1000 socks5 ip port USER PASS proxy -n -i127.0.0.1 -p3128 and set 127.0.0.1 port 3128 in iPhone proxy configuration.

					3APA3A: Re: use 3proxy on ipad for socks 19.01.2012 3:03:05
					Ali, I never did it by myself, you better search something like "tether iPhone 3proxy" to get step-by-step instructions.

	Dennis: ad block 16.01.2012 20:52:07
	I did a chd filter a while back. At that time I had a good ad blocker. But now I find I need a https adblock, since everything is going https. The other proxies don't do https. I am using host ad blocking, but many ads are getting through. It took me a while to build the child list. So, I was wondering if anyone has a premade ad block filter made up, using the two relevant plugins.

		3APA3A: Re: ad block 19.01.2012 3:01:25
		Yes, it's possible to decode and filter HTTPS traffic by spoofing SSL certificate and this techinque was successfully tested with 3proxy. I hope to add https hijacking plugin into final 0.7 release then I find a time to make it.

		3APA3A: Re: executable file & config 13.11.2011 13:55:55

		3APA3A: Re: SOCKS Speed 10.10.2011 3:34:38
		SSH uses encryption and is very CPU-intensive. If you have high CPU load (100% / number of cores) from either side, it's ssh CPU usage to cause the bottlneck

			Soroush: Re: SOCKS Speed 10.10.2011 20:43:33
			u mean , i shuldn't use both SSH and iproxy in the same time?

				3APA3A: Re: SOCKS Speed 11.10.2011 0:27:34
				I mean you shouldn't use SSH for this kind of things. It was never ment to.

	planeta: 3proxy for Xen virtualization 01.10.2011 16:40:24
	Hello! When I try 3proxy for Linux (CentOS 5.5) on VPS with OpenVZ virtualization I catch success and all my socks work correct. But when I try install 3proxy on VPS with Xen virtualization I can use only one socks. How I can install 3proxy on VPS with Xen virtualization with Linux (CentOs 5.5 for example) and use 2 or more socks?

		3APA3A: Re: 3proxy for Xen virtualization 02.10.2011 0:20:49
		Try to check you have no limits (e.g. ulimits) for some resources. It's not enough information, 3proxy should not depend on virtualization.
