Adding virtual ip in Ubuntu 11.10

[call_krushna]

Hi Everybody,

I want add virtual ip for my pc(Ubuntu 11.10).I have edited the file
#vi /etc/network/interface and added the below line

auto eth0
iface eth0 inet static
address 192.168.0.190
netmask 255.255.255.0
broadcast 192.168.0.255
gateway 192.168.0.8
auto eth0:1
iface eth0:1 inet static
address 192.168.0.41
netmask 255.255.255.0
broadcast 192.168.0.255
gateway 192.168.0.8

But while restarting the network service gives the below error

Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces
* Reconfiguring network interfaces... RTNETLINK answers: File exists
Failed to bring up eth0:1.

Any suggestion highly appreciated .

Thanks in advance

Did you uninstall your network manager?

Hi,

I face exactly the same problem with ubuntu 11.10...it works fine with 11.04 then it failed tu bring up after upgrade to 11.10...have you found the workaround?

This link looks like it has relevant information:
http://www.linuxquestions.org/questions/linux-networking-3/rtnetlink-answers-file-exists-error-when-doing-ifup-on-alias-eth1-1-on-rhel5-710766/

I've found that even though I can't see the virtual NICs they are responding. In that link, the OP mentions "Further read indicated there is an option for alias files to start the alias interface at same time as primary or not. The default is to start at same time." Anyone have a clue how to change that?

Hi chakhedik (http://ubuntuforums.org/member.php?u=996901)

This is a known bug in 11.10 (https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/876829).

You could create the interface manually in /etc/rc.local. Remove the definition in /etc/network/interfaces, then edit /etc/rc.local and add this command:



ifconfig eth0:0 192.168.0.41 netmask 255.255.255.0 broadcast 192.168.0.255

You don't need a gateway directive; the aliases always use the same gateway as the physical adapter.

That report says a fix was released last month, but I'm still having the problem. When should we expect that to trickle into the repos?
