Hi!
I build and use vservers where the guests need to cooperate with each
other. That is, a system with with guests running Postfix,
PostgreSQL, or Apache ( multiple guests as they are mod_perl driven
) and they all need to communicate with each other. So I want to
build a Virtual LAN ( different from my take on a VLAN ) with virtual
NICs.
Basically the traffic never hits the physical LAN/WAN.
That make sense? IS it possible? If so what what should I be
looking for in my research?
Yes it is possible, with the dummy net interface. You'll have to
enable the dummy net driver support (CONFIG_DUMMY=y) in your kernel.
Thanks Chris. Is there a way test for this? I could ask Daniel if it
got set in the Fedora Core 5 RPMs he built but that would be _really_
lazy. :-)
ifconfig dummy0 <IP address>...
But yes, it is enabled in Fedora's kernels.
