 Posted: Fri Sep 03, 2004 10:05 pm Post subject: multiple IP addresses on one server |
 |
|
I have a dedicated gentoo web/email/ftp server and the hosting provider has given me 3 IP addresses to use on my machine.
How do I add them to my machine?
One of them is working and active but the other two are "dead" as they haven't been "added" to my server.
Would I add them in the /etc/conf.d/net file? For example, would this work?:
| Code: |
iface_eth0="204.225.92.134 204.225.92.137 204.225.92.138 broadcast 204.225.92.128 netmask 255.255.255.0"
|
...by just putting them all in line like that?
I'm asking first because I'd hate to reboot and lose contact w/ my box. Then I have to pay tech support to fix my n00b evil ways.
Thanks! |

zambizzi,
You add the inactive ones as alias es with ifconfig
the form of the command is
| Code: | ifconfig eth0:1 ....
ifconfig eth0:2 ..... |
You need the right odds and ends in your kernel.
They work like seperate interfaces, so you need to update your routing table too.

Care to elaborate? Routing table? What exactly is required in the kernel so I know if I'm missing it or not?
I'm *very* new to Gentoo and though not a n00b w/ linux, have never delved this deep into the system.
Thanks! |

This is how I do it..
This is a snip from /etc/conf.d/net. xxx.xxx.xxx.xxx will need to be replaced with your IPs.
| Code: | # primary ip value for eth0
iface_eth0="xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx"
# set up aliases... seperated by spaces
alias_eth0="xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx "
netmask_eth0="255.255.255.255 255.255.255.255"
gateway="eth0/xxx.xxx.xxx" |
when you do a ifconfig, you should see interfaces listed like this:
| Code: | eth0
eth0:1
eth0:2
lo |
All you need to do see the change is do /etc/init.d/net.eth0 restart
