| 34 | <PRE>Hello, IRC. | |
| 35 | ||
| 36 | Some good guys do regular attacks on my irc network using many | |
| 37 | different hosts in parallel. Very often, this is done using open proxies. | |
| 38 | Is this possible to implement simple port scanning algorithm to | |
| 39 | detect clients with many open tcp ports (or detect blacklisted port | |
| 40 | numbers or ranges of them) and block the connection? The problem is | |
| 41 | real one. Help please. Server software is bahamut-based fork with | |
| 42 | support of Russian codepages translation. | |
