| Post subject: | Ubuntu 11.04 Static IP |
Hi, I am currently looking over the Ubuntu server guide* and it talks about configuring a static IP address assignment. Making the following changes in the /etc/network/interfaces file (changing the address details): Quote: auto eth0
iface eth0 inet static address 10.0.0.100 netmask 255.255.255.0 gateway 10.0.0.1 Is this necessary and if so why would you want to do this? *https://help.ubuntu.com/11.04/serverguide/C/network-configuration.html |

I believe it is needed if you want to use a local LAN IP as well as the public IP. You have a single interface in your linode so supporting multiple IP's comes by defining virtual interfaces. |

Ya know, I noticed this in the Linode static IP config article. But it seems it's totally possible to keep your external IP using DHCP, and use a static IP for your internal; something like: /etc/network/interfaces: # The primary network interface auto eth0 eth0:0 iface eth0 inet dhcp iface eth0:0 inet static address 10.0.0.2 netmask 255.255.255.0 Is there anything wrong with doing it this way? I'm wondering if there's a specific reason behind the way the linode article is written. |
