Title: Users have same ip addresses

Strange bug in 0.4.1.1-posix (run on freebsd).

After some days hub start to see many users under same ip, but ips are different!
Restart helps, but every day restarts isn't a good idea...

We run 0.4.1.1 on ubuntu and gentoo with several thousand users but I never faced this problem. Can you show some example?

Today it happened again.
I see many same ips in user list. When i check ips using lua script, i see same addresses too.

Perhaps this is related to option #53 (Check IP in commands). Now i turned it on, perhaps this will help.

Also, how can i view some debug log?

With the UDP Debug Receiver (http://www.ptokax.org/files/PX-UDP-DBG-RECV-2.2.1.7z) and the "!debug <udp_port>" command :)

Nothing... Debug log is empty.
Also this bug goes every two days, and i restart a hub.

All scripts i wrote myself :)

it appears that the number of users with the same address is no more than setting #112 - Maximum users from same IP.

I don't think that the error was in one script, because all the scripts see user with one address, although it should be another.
And hub sends $UserIP with this ip too.

Have you got some compile warnings?

This could be done by a simple "firewall" and/or "router" error config, either hardware or software.
I suggest checking both.

I started ptokax on another server (freebsd too). 0 users, only me.

I see a lot of messages: "[ERR] accept() for port 411 has returned an INVALID_SOCKET" every one second.
What is it? :)

Try higher port number then 1024...

[ERR] accept() for port 56734 has returned an INVALID_SOCKET

This is very strange :)

Also, there are no error messages when hub runs on windows.

I am in no way a programmer but digging through the web I found that invalid_socket should not be returned under Unix. Look at this page (http://ubuntuforums.org/archive/index.php/t-903776.html).

You will get this message on any (but 2) errors in accept(). The "timering" (1 error/sec) is very interesting :)
