Error: failed to bring up eth1

[Pavitra Shetty]

Hi,
we are installing UEC (ubuntu enterprise cloud) which requires 2 machines to be connected as below :
A cloud controller (one system) connected to public network through eth0.
A node controller (another system) connected to the cloud controller through its eth0 on cloud controller's eth1.

For this configuration we added foll lines to /etc/network/interfaces file on cloud controller :

auto eth0
iface eth0 inet dhcp

auto eth1
iface eth1 inet static
address 192.168.20.1
netmask 255.255.255.0
network 192.168.20.0
broadcast 192.168.20.255

However, on restarting the network it shows the error-

SIOCSIFADDR: No such device
eth1: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
SIOCSIFBRDADDR: No such device
eth1: ERROR while getting interface flags: No such device
eth1: ERROR while getting interface flags: No such device
Failed to bring up eth1.

It fails to connect on eth1. Please guide.

It might be an issue with the persistent files under
/etc/udev/rules.d/ On a side note, isn't NetworkManager supposed to
handle the IP and related assignments ?

Just to make sure, you have two ethernet ports right? or one ethernet one wlan?

Could you please confirm that eth1 is indeed present with a ifconfig
-a | grep eth

Thank You,

@ Shravan: ifconfig -a gives only eth0.
@ Gaurav: we have one ethernet port.

Interpreting what you have quoted -

"A node controller (another system) connected to the cloud controller
through its eth0 on cloud controller's eth1"

you will need 2 lan / ethernet cards on your "cloud controller"
machine. Once you have installed the second Ethernet card you should
be able to see the eth1 interface.
There can be no interface without its respective hardware :)

I second Shravan and/or what you can do is, use wlan0 (Wireless Card) in replacement to eth1 if you have that.

Cheers!

We got the solution. To establish the second interface, in the interfaces file,
instead of eth1 write eth0:1 This creates a new eth1 type interface and that we can configure in interfaces file as needed earlier.
Thanks.
