Hello brave guinea pig,

Damn, you're also running NFS on that machine!!

Truely amazing! I wish I could login to this machine and do some tests.

Well we run ISP services for 53 different domains.  Each domain get's their
own IP address, thus 53 VIPs.  Each of those 53 VIPs get their own mail,
pop, web, radius, etc. etc.  Thus the 53 VIPs * 8 services each, * number of
realservers.

Yep, now it does make sense to me.

I think I can take the 8 services each down to 3.  FTP and POP need to have
their own IP address they listen to so I know which domain the user came
from, so they just need to use their username instead of username@domainname
to authenticate.  HTTP-SSL needs it's own IP address for each domain since
you can do named virtual hosting with apache+ssl.  The rest of the services
can just listen to the realservers main IP address.

Exactly.

All that should help, but it still leaves me with 1000 RIPs

I don't think the amount of VIPs or RIPs is the problem

Glad I be the first! Don't know whether I should :) or :(

You will be very famous and all girls want to know you and all the guys want to be like you :)

Cheers,
Roberto Nibali, ratz
