Ubuntu Server 9.10 -- Bond 2 NIC's

[dasunsrule32]

I would like to do a couple of things, I am running a Dell Poweredge 2850 and want to bond the two NIC's. I was looking here to do the bonding. It get's a little more tricky with what I want to do from here, I need to two virtual adapters on top of the bond: one at IP 192.168.56.2 and 192.168.56.3. I am binding SSH to the first IP.

Is it possible that I do this config over SSH? It may be asking a lot to do this, but since I have SSH already configured to bind to 192.168.56.2, if I put the config together (assuming it is correct), it should work after restarting the networking service. If anyone could shed some ideas on this and how to accomplish this, it would be awesome! Thank you!

Although, your 'interfaces' file would look 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
auto bond0
iface bond0 inet static
address 192.168.56.2
netmask [SUBNET MASK]
gateway [DEFAULT ROUTER]
network [NETWORK ADDRESS]
broadcast [BROADCAST ADDRESS]
post-up ifenslave bond0 eth0 eth1
pre-down ifenslave -d bond0 eth0 eth1

# The secondary network interface
auto bond0:0
iface bond0:0 inet static
address 192.168.56.3
netmask [SUBNET MASK]
network [NETWORK ADDRESS]
broadcast [BROADCAST ADDRESS]

You can add as many secondaries as you need...

bond0:1
bond0:2
bond0:3
etc...

Thanks, I will take a look at this later in the week. I will let you know how it goes.

I run a bonded setup just like this. It works well with the method outlined by KiLaHuRtZ.

I am going for it over SSH, I will let you know if I lock myself out or not.

I want to basically provide more bandwith to the server? Is this going to do what I need? Thanks!

Is the the correct line for /etc/modules?

bonding mode=active-backup miimon=100 primary=eth0

Is this the correct setup for my config I will be using below:

# 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
auto bond0
iface bond0 inet static
address 192.168.56.2
netmask 255.255.255.0
gateway 192.168.56.1
dns-nameservers 192.168.56.89
post-up ifenslave bond0 eth0 eth1
pre-down ifenslave -d bond0 eth0 eth1

# The secondary network interface
auto bond0:0
iface bond0:0 inet static
address 192.168.56.3
netmask 255.255.255.0

Use 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
auto bond0
iface bond0 inet static
address 192.168.56.2
netmask 255.255.255.0
gateway 192.168.56.1
network 192.168.56.0
broadcast 192.168.56.255
post-up ifenslave bond0 eth0 eth1
pre-down ifenslave -d bond0 eth0 eth1

# The secondary network interface
auto bond0:0
iface bond0:0 inet static
address 192.168.56.3
netmask 255.255.255.0
network 192.168.56.0
broadcast 192.168.56.255

Place your nameservers in '/etc/resolv.conf'...

nameserver 192.168.56.89

This will not provide more bandwidth, just fault tolerance. If you want more bandwidth, you need to do the 802.3ad mode. However, you switch needs to support 802.3ad to work.

I have two Dell Powerconnect 3024's, they support Link Aggregation aka Port Trunking. Would my /etc/interfaces file end up changing at all or would /etc/modules be the only config changing?

EDIT: This is how my /etc/modules looks now, if it isn't correct, please let me know. Thanks!

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

loop
lp
rtc

# mode=0 (balance-rr), mode=1 (active-backup), mode=2 (balance-xor), mode=3 (broadcast), mode=4 (802.3ad), mode=5 (balance-tlb), mode=6 (balance-alb)
bonding mode=4 miimon=100

That should work, but you might wish to have a look at this...
