http://ubuntuforums.org – Hi ! I'm trying to set up a virtual machine on an Ubuntu Server 12.04, but at the moment I've some difficulties to ping internet/host... I'm really bad with network stuff so, If you could help me it would be great !! So First of all I added a bridge br0 in my /etc/network/interface Code: # 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 auto eth0 iface eth0 inet manual auto br0 iface br0 inet static   &nbsp (Hardware)

Hey all,

I'm having a really odd issue.

I just upgraded my 11.11 server to 12.04, by performing a clean install.

I edited my /etc/network/interfaces file to the following:

Code: # This file describes the network interfaces available on your system # and how to activate them.

Hi All,

I have 2 NICs in my U9.04 Server box (eth0, eth1). After I added 2 virtual interfaces for each physical interface (eth0:1,eth0:2,eth1:1,eth1:2), the MAC addresses of all the interfaces have changed to that of eth0. Because eth1 was configured to be on my local network, I can't access the box remotely anymore.

I'm wondering if I've found a bug in ifupdown, but I wanted to ask here before reporting a bug:

/etc/network/if-up.d/upstart seems to fail to emit static-network-up if any virtual interfaces are defined.

Virtualbox FTP to host 8 weeks 5 days ago

For testing purposes I installed virtualbox to simulate a linux(64 bit ubuntu) server.

I configured my network settings like this: Adapter 1: NAT Adapter 2: Host-only

with my etc/network/interfaces configured like this:

#loopback network interface auto lo iface lo inet loopback

# primary network interface auto eth0 iface eth0 inet dhcp

#the host-only network interface auto eth1 iface eth1 in

Hi, yesterday I've done a release upgrade from 10.4.1 LTS to 10.10 and I faced the following issues:

1) br0 does not bridge anymore eth0 and wlan0 (I have a DNMA92 wireless card that runs ath9k drivers) at startup even if specified in /etc/network/interfaces:

Code: auto lo iface lo inet loopback pre-up /sbin/iptables-restore < /etc/network/firewall-rules.conf

# The primary network interfac

Have a 'new' mailserver running postfix on Ubuntu.

We are having some problems configuring the subnets & interfaces.

Basically 2 subnets (.253. & .254.) need to be connected through the 3rd subnet (.252.) where the Router is residing.

I got a new hard drive for my computer a little while ago and upgraded to ubuntu 10.04 LTS from 9.10.

I have debian hosts which are connected through trunk port on 5 different vlans. But this host respond to arp "who-has" requests of all of their differents ip.

On debian squeeze, I setup a bridge based on eth0.
