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):
auto eth0 iface eth0 inet static address 10.2.3.4 netmask 255.255.255.0 network 10.2.3.0 broadcast 10.2.3.255 gateway 10.2.3.1 # Extra IPs: post-up for last in `seq 110 118`; do ip addr add 10.5.4.$last/32 dev $IFACE; done || true pre-down for ip in `ip addr show dev $IFACE | sed -n 's@.* inet \([0-9.]*/32\) .*@\1@ p'`; do ip addr del $ip dev $IFACE; done || true
Yes, it's ugly as shit, but I can't think of a neater way to do it.
