Server doesn't want to connect to the wired network

http://askubuntu.com – I just got home and moved my server from my apartment to my house, and for some reason my Ubuntu server doesn't want to obtain an IP from our router. It is setup for a dynamic IP, and it was working perfectly fine before I moved it. I'm currently getting a "Waiting for network configuration..." during boot before it times out. My /etc/network/interfaces file looks like: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp I've also tried setting a static IP but no other computer on my network can hit it. As I've said, I changed nothing to the network config, the only thing that c (HowTos)

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.

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.

Wlan0 Static Ip bridge 20 weeks 3 days ago

EDIT: Even taking br0 out, still cannot get a static IP connection.

I had the following /etc/network/interfaces configuration and it was working

auto lo iface lo inet loopback

auto eth0 iface etho inet manual

allow-hotplug wlan0

auto wlan0 iface wlan0 inet dhcp wpa-ssid "xxxx" wpa-pskl "xxxx"

auto br0 iface br0 inet dhcp bridge_ports wlan0 eth0

I changed the config for wlan0 to the followi

I just did a recent install of Ubuntu Server 12.10 (no GUI, command line only) on a new system. I noticed that upon booting the server does not obtain an IP address from my router. However, once I log into the machine locally the server shows up on my list of DCHP clients and I can connect remotely without issue.

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

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.

Ubuntu 12.04, cli only, on an old machine

I swear, it was working. But now, on boot I get "waiting for network configuration" for a while, then it says "waiting an additional 60 seconds for network configuration". When the machine finishes booting, I have no network.

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 upgraded my Internet connection, and after changing the Modem my Ubuntu Server's eth0 doesn't come up.

I looked at /etc/netwrork/interfaces, it looks all normal eth0 is set to auto and dhcp

# The loopback network interface auto lo iface lo inet loopback

# The primary network interface auto eth0 iface eth0 inet dhcp

In the boot process right after Ubuntu starts to run, the lights for the por
