Quick post. If you have multiple IP addresses (i.e. a range) assigned to you server, and you want to listen on all of them (i.e. multiple SSL sites), then rather than using the ancient eth0:1 syntax, you can hack
/etc/network/interfaces to use iproute2 properly.
Assuming the IP 10.2.3.4, with the extra range of 10.5.4.110-10.5.4.118 (yes these extra ranges often ignore class-boundries):
Yes, it’s ugly as shit, but I can’t think of a neater way to do it.
Update: Better solution
