I administor a small isp with about 1000 customers.  We have sun ultra 10 30
0
mhz with 512mb memory.  I have solaris 2.6 running, with apache, dns, sendma
il,
tacacs-plus running also.  My problem is that this server gets really slow a
t
times.  I think we have too much running on one server.

What I  need to know is if I can put some of these things, like sendmail and
maybe tacacs-plus on another server.  I have 3 more sun ultra 10's 300's.
My other problem is I only have one domain name for the isp.  All mail is ro
uted
to this domain name.  If I put sendmail on another server, I will have to se
t up
some form of domain name and that won't work, can't have two of the same dom
ain
names with one sendmail.

Anyone know of a way I can get this job done with what I have to work with??


Thanks

Ralph

Well, assigning multiple machines to the same DNS entry is the obvious
example.

If you're short on IP numbers and/or for whatever reason don't want the
revolving IP solution you can use 1 machine to forward the request on to
several of your other (local) machines using load balancing using port
forwarding.

The keyword to look for is "load balance", and there are quite a few
solutions out there, all for different problems.

I'm a developer more than an administrator, but my experience has been that
you really need some type of network file system in place for this to work
correctly, (all the machines need the same 'view' of the common data, simply
copying the files over won't generally work.)
