I think vconfig from vlan.1.8.tar.gz goes well with 2.4.26, but on the other hand it doesn't really matter much, any version of vconfig that works for you is fine. The interface between kernel and userspace hasn't changed all that much so even old versions of vconfig work properly. > And where should I copy the file vconfig ?

Dunno, but I seem to remember people posting to this list with answers on how to do it neatly in RedHat. > On a Debian server, I have tried to do this an dit work well : > < auto eth0.2 > iface eth0.2 inet static > address 192.168.1.1 > netmask 255.255.255.0 > pre-up /usr/local/sbin/vconfig add eth0 2 > > What is the best practice ? It depends on the distribution. I've seen a couple of different ways but they all fit into the distribution's normal method of configuring network interfaces. > 4) > I want to change the IP address, and want to use trunk 802.1q to > help me doing that by creating two vlans per server and per NIC, do > you know if the applications like apache, mysql, dns server, > postfix server, etc > will accept and work with two IP addresses per server in their > config files ? Most server software can be configured to listen on the INADDR_ANY address, which means "all configured interfaces" including VLANs. If you want different server behavior depending on the incoming destination address you'll have to make sure there's special support for that in the servers however, but I know that at least Apache handles IP-based virtual hosts without problems. > If anyone has already changed Ip address by using 802.1q, I will be > happy to accept your advices. I guess that's not so different from migrating IP adresses without VLANs, just more handy since you can easily keep the system working on the old address(es). > 5) > I have a broadcom card, should I use the driver tg3 or bcm5700 > (version 7.3.5) for trunk 8021q ? Does it need to patch ? I remember several posts to the mailing list saying that a Broadcom driver worked out of the box. I think it was the bcm driver, but I'm not sure.
