Paul;

Thank you for your response.

I have 3 SSL sites (each with there own ip) and many Name Based sites running
on one ip.

In my test setup I have:

I have IPROOT="208.153.105.17 208.153.105.18 208.153.105.19"

when starting the vserver, it identifies that it is using the virtual
addresses.

this is what starts my ips up when my vserver starts.

pre-start)
        /sbin/ifconfig eth0:vw01 208.153.105.17 netmask 255.255.255.240
        /sbin/ifconfig eth0:vw02 208.153.105.18 netmask 255.255.255.240
        /sbin/ifconfig eth0:vw03 208.153.105.19 netmask 255.255.255.240
        ;;

Normally I use:
NameVirtualHost 208.153.105.19
<VirtualHost www.somedomain.com>
</VirtualHost>

Which works well on the old server, and that I want to move into a vserver and
retire the old beast.

and I also tried it as you displayed below, but apache never binds to the
other 2 ips. A port scan reveals port 80 is not listening.

btw I'm using kernel 2.4.19ctx-13

Thank you for the tips on ip conservation, I'm well aware of them, and I am
familure with the conf options, I've been using linux since 1995, along with
apache, etc.

I've been looking for a sane vserver implimentation for some time, and I
beleve this is it. I have several vservers running, and working well.

This one, where I really need several IP's in one vserver is making my brain
swell.
