I few things to remember about bahamut configuration that isn't needed on other ircds.
1> Do NOT use SERVICESHUB unless you know what you are doing. Anope will work with SERVICESHUB, however botserv's public commands won't work. This is because in SERVICESHUB mode, services uplink does not send channel traffic to services to save bandwidth. So no function in Anope will work if it relies on monitoring channel traffic.
2> you have to set both your services name as well as the stats name to your services name. This is because on DALnet, OperServ is on a different server than the rest of services. IIRC it was done this way so if the main services server drops, the ntwork can still be controlled from an IRCop standpoint, mainly for triggers and akills.
3> HostServ will not work as Bahamut doesn't support vHosts. Bahamut does have oper hostmask hiding but that's not using vHosts, but I:Lines.
Hope this helps.
