Assigning an additional IP to a Dedicated

AsuraHosting

Hey guys, I just got a new server and I was trying to assign a secondary IP to the dedicated server; but every time I restart the networking, it cuts me off from the server; so I'm sure that I'm probably just doing it wrong.

The server is on Debian 6.0.4 (Squeeze); and I was following this: http://wiki.debian.org/NetworkConfiguration#A.2BAC8-etc.2BAC8-network.2BAC8-interfaces

It doesn't seem to work... if anyone could help point out how to do it, I'd appreciate it a lot! Thanks in advance.

I'm guessing your editing /etc/network/interfaces manually? If so, you either need to do auto eth0:1, etc, or when you restart networking, do it with /etc/init.d/networking restart && ifup eth0 && ifup eth0:1, etc, since restarting networking in this fashion doesn't auto-up the interfaces unless that auto flag is set.

Example:

-22:14:26- Inhert:~ :: aldryic % cat /etc/network/interfaces 
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
auto eth0
iface eth0 inet static
        address 12.34.56.78
        network 12.34.56.0
        gateway 12.34.56.1
        netmask 255.255.255.0
        broadcast 12.34.56.255
        dns-nameservers 8.8.8.8 8.8.4.4 4.2.2.1 4.2.2.2

auto eth0:0
iface eth0:0 inet static
        address 23.45.67.89
        network 23.45.67.0
        gateway 23.45.67.1
        netmask 255.255.255.0
        broadcast 23.45.67.255
        dns-nameservers 8.8.8.8 8.8.4.4 4.2.2.1 4.2.2.2

Yeah I'm a bit confused; I tried to add the following, but it locked me out of my server and I was forced to access it through KVM...

auto eth0:1

allow-hotplug eth0:1
iface eth0:1 inet static
address sec.on.dar.y
netmask 255.255.255.0

Aldryic

eth0:1 is a virtual interface, you can't "allow hotplug" it :P Remove that line, add the network, gateway, and broadcast, and you should be set.

AsuraHosting

@Aldyric; I don't have a broadcast, it should work fine right?

By the way, thanks a lot for the help; really appreciate this man

Aldryic

No worries, I fought with the same thing myself :P Broadcast isn't always necessary... but if you're not running DHCP you do need to declare a gateway.

I'm trying to fix it up, but it seems to be not working correctly...

root@debian:~# /etc/init.d/networking restart && ifup eth0 && ifup eth0:1

Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces ... (warning).
Reconfiguring network interfaces...SIOCDELRT: No such process
SIOCADDRT: No such process
Failed to bring up eth0:1.
done.

My /etc/init.d/networking looks like this

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet static
        address 173.208.228.x
        netmask 255.255.255.0
        gateway 173.208.228.y

auto eth0:1
iface eth0:1 inet static
        address 173.208.228.x+1
        netmask 255.255.255.0
        gateway 173.208.228.y

Ah, I found out the solution... just needed to remove gateway.

Thanks for everything @Aldryic !

Aldryic

No worries
