Hi..
I've got the next problems with my ircd.

1. I can not get more than 20 connections to my server.
   When i reach 20 users, mirc says, 
   Closing link. Server - No more connections.

2. I try to conect two ircd server with the same version.
   And i couldn't. It say when I try to connect 'em:
   Connecting to server .......
   But i doesn't do it??..

So I'm sending my ircd.conf files for each server...
