Hello, I had in the past 2 IP addresses on my Fedora. after I boot , ifconfig still shows 2 IP addresses: on eth0 : 192.168.0.10 and the second one is an external IP on eth0:1 is (for example) 201.121.241.115 Most of the time I need only the inner ip ; so I renamed ifcfg-eth0:1 under /etc/sysconfig/network-scripts to ifcfg-eth0:1.old. ifcfg-eth0:1 is the file containing the externa IP definition , 201.121.241.115 Bur still after boot I do still get both IP addresses I had , on eth0 : 192.168.0.10 and on eth0:1 201.121.241.115 I grepped for 115 under /etc/sysconfig/network-scripts , and the only occurrence was in ifcfg-eth0:1.old. So from where does it takes the 201.121.241.115 for eth0:1 after boot even that I renmed the file name to ifcfg-eth0:1.old.? and what should I do to avoid it ? Regads, John
