IP Alias

I tried to add an ip address (/etc/sysconfig/network-script/ifcfg-eth0:0) to my server, but when I did "service network restart", the network service went down but didn't restart. Consequence: a trip to Brussels for setting the network settings back to correct values. Took me three hours to get there and back, but since I stopped in Leuven and ate in "The Ribs" there, my day wasn't completely spoiled after all.
