Realms are groups of web pages requiring authentication. If you identify to one page in a realm, you're identified to all pages of the realm. You can also configure one of WebMaster's core name servers as extra name server. This command will set an IP that your server will connect out with. This is handy in the case where a remote server has strict IP checking on to a multi homed machine.
Log rotation causes a new log to be started every day.
The log file will be named after the day of the year which it holds entries for. Users cannot remove the 'q' mode. It can be placed on specific clients by placing it in the initial mode string in the client class that they connect from. It can also be placed on clients using the External Authentication code. If the administrator is on an encrypted client then he can sajoin the channel and if the target of an fjoin is encrypted then the fjoin command will work like normal.
