Blitzed Open Proxy Monitor 3.1.3

Blitzed Open Proxy Monitor or BOPM, is an open source open proxy monitor, designed for use with hybrid-based ircds, although it can be used with slight modification on any server which has the ability to show connects to opers and that supports KLINEs.
BOPM is known to work without modification on the following ircds:
- Bahamut (tested with 1.4.28, 1.4.30)
- Hybrid (tested with 2.8/hybrid-5.3p8, ircd-hybrid-6.3 and ircd-hybrid-7)
- ircd-ratbox (tested with > 2.1.8)
- charybdis (tested with > 2.0.0)
- Unreal (tested with 3.1.2 and 3.2)
- Dancer (tested with 1.0.31)
- TR-IRCD
- IRCu
- Ultimate (tested with UltimateIRCd 2.8.8 and 3.0.0.b3) - please note, earlier versions of Ultimate IRCD are not supported
- LiquidIRCd (tested with 1.0.4)
- InspIRCd (known to work with 1.0 and 1.1 version branches - instructions are given here)
Please note that BOPM will not work with older versions of Unreal without modifying Unreal to send the clients IP address in a connection notice. Patches are also available for download. On the latest versions of Unreal this is no longer needed. Remember for all Unreal versions you must set the perform line correctly (documented in the config file).
How does it work?
When a client connects to the IRC server, BOPM scans the client for open proxies. It then determines whether they are really open by using them to connect back to the server.
How does BOPM improve on first generation scanners (wgmon, tcm, oomon)?
It extends them by adding support for SOCKS4, SOCKS5, WinGate, HTTP proxies, insecure Cisco routers, simultaneous connections, and a more scalable model (written in C). BOPM also has support for a DNS blacklist, similar to MAPS RBL+ or Visi RSL
BOPM is in use without issue on servers receiving over 400 connections per minute during normal real-world operation (as in, regular client load excluding bursts and attacks). That is 7 user connections per second, enough for even the largest of IRC servers.
Additionally, BOPM contains the ability to match hosts against a DNS blacklist such as DroneBL or your own custom list, it can also submit new proxies that are found via email if the list accepts them.
Enhancements:
- This version was fixed to work with GCC 4 and various other cleanups.
