changing xx connections on port
 

Hi , i wanna know if any change to change the max connection per port , couse i got a slackware 10 , kernel 2.6.9 ,
and i wanna place more than 1024 users per IRCD, but the problem its that's limited by kernel o IPV4 to 1024 connection simultaniuos per port

i'm not really sure what you mean -- ports really only handle one conection at a time
listening ports make new ports for new connections.
you might be talking about (ulimit) limit on open file descriptors a process like a server can have
everything in Linux is files.
"ulimit -n" for me returns 1024 like you said
i think you change that as root with
ulimit -n <newnumber>
most likely can put that in /etc/profile or something to make it permanent
