  39 </I>&gt;<i> Hello, IRC.
  40 </I>&gt;<i>
  41 </I>&gt;<i> Some good guys do regular attacks on my irc network using many
  42 </I>&gt;<i> different hosts in parallel. Very often, this is done using open proxies.
  43 </I>&gt;<i> Is this possible to implement simple port scanning algorithm to
  44 </I>&gt;<i> detect clients with many open tcp ports (or detect blacklisted port
  45 </I>&gt;<i> numbers or ranges of them) and block the connection? The problem is
  46 </I>&gt;<i> real one. Help please. Server software is bahamut-based fork with
  47 </I>&gt;<i> support of Russian codepages translation.
  48 </I>&gt;<i>
  49 </I>&gt;<i> --
  50 </I>&gt;<i> Sincerely,
  51 </I>&gt;<i> Vitaliy Ovsyannikov
