This is the HostServ.
It's recommened to use the midircd, because in the original snircd is an issue with the user mode +h and doesn't G-Line setted hosts.
It hides the hosts for all users in your irc network :)
It's recommened to compile the sources with NetBeans
As an alternative can you download a precompiled package HostServ.zip. To run this service, you must use jre17 or higher.
