Ubuntu Servers :: /etc/network/interfaces Doesn't Set IP Address With OpenVZ?
Jun 4, 2010
I'm building up a server based on 8.04 LTS. It's using OpenVZ, and as part of that it creates a virtual network interface venet0. I add a stanza to /etc/network/interfaces that looks like this:
Code:
allow-hotplug venet0
iface venet0 inet static
address 10.53.35.1
netmask 255.255.255.0
[Code].....
Looking further, I note that /etc/init.d/networking is not symlinked into anything other than the rcS.d directory. It's been a while since I've been tinkering at this level, but I understand that there should be a symlink from rc2.d/Sxxnetworking into ../etc/init.d/networking. So I wonder where eth0 is getting configured.

I have three VMs (VMWare Server 2) all running Ubuntu Server 10.04. (one I asked to be a samba share from the outset, the others are blank server installs, no pre-config)
I follow the layout in the community documentation regarding setting up firewall rules through iptables. I.e. I create a file called iptables.rules and place it in /etc. I then modify the /etc/network/interfaces file to look like this:
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
[Code].....
However this third one I have reinstalled Ubuntu 3 times now, and every time as soon as I modify the /etc/network/interfaces file, eth0 fails to start up (is not visible in ifconfig, only the loopback adapter), and no networking works.
I have tried reducing the iptables.rules file (which is a carbon copy across all machines anyway) to a basic accept all rule, and it still doesn't like it. As soon as I remove those two extra lines in the interfaces file, the network starts up no problems and eth0 is there.

In Ubuntu 9.10 I configured manually network settings to /etc/network/interfaces, and it works fine when I run /etc/init.d/networking restart.
Problem is that those settings are not loaded to GUI application (Preferences/Network connections).
I don't want to edit my preferences there, I just want to use my interfaces file as default! Do you know what's going on?

I have been trying to set up Ubuntu server 10.04-2 and am a couple issues.
One issue is that the network interfaces aren't starting properly. I have to start them manually. I've tried to edit the /etc/network/interfaces with the following.
Code:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static

how to edit and save this file using Vim-noX. (connected via putty) I have the file loaded up and Ive inputed the needed data for my static IP, but I cant for the life of me figure out how to close and save my settings. At the bottom of the command line I have "INSERT" which toggles with "REPLACE" and I just cant figure this out.

Last night I created a fresh install of Ubuntu Server 10.10. I was working through a tutorial to set up a development server for home use, and everything worked perfectly. I was able to install OpenSSH, Apache, MySQL, and PHP (and Vim) with no problems. I was also able to use "ifconfig" to determine the network address of the server and I was able to view web pages on the server from another machine on my home network, using a browser. So, everything was "peachy". [By the way: The server is connected to the router using a CAT5 cable. This is a WIRED connection] I shut the Ubuntu server down at the end of the night and, now that I have rebooted this morning, I have apparently lost the network interface. I cannot ping anything from the server. If I run ifconfig, only the "lo" configuration is listed, with the 127.0.0.1 address.

If I try to add a new interface (eth1) to /etc/network/interfaces, I get
Code:
* Reconfiguring network interfaces... SIOCSIFADDR: No such device
eth1: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
[Code]...
How do I add 2 interfaces and get anyone of them to work, as available ?

I'm trying hard to run an openvpn server on a openvz VPS, the problem is packets sent from openvpn server process, doesnt reach the client, so connection is never stablished (I run tcpdump on server and wireshark on client to carefully investigate whats wrong), the first guess is that a kind of firewall is blocking traffic (I tried connecting to server through different ISP's but it's possible the national network provider applied some filtering but it cant be on IP,src port or dst port as I'd tried different configuration.
what about deep packet inspection technics, is it possible to block my traffic?) but at exactly the same time I can transmit UDP packets using netcat from server to the guest. there is no firewall enabled in between, I had tried, tcp and udp, tried both open vpn and openvpnAS and tried any thing one can imagine! the VPN is configured as a routed (TUN) type on debian

Ubuntu LTS 8.04 + DHCP. Works fine except for fixed addresses. I mean all devices which need to get fixed IP according to their MACs don't get them and keep to receive random IPs from the range (almost everytime all machines receive the same IP they got from DHCP for the first time).

I have installed Ubuntu 8.10 Server Edition on Virtual Box. When I start the virtual machine I do not have connection to my home network. The router I have does not assign any IP address to this machine. Now I have some questions which I am finding hard to find answers for over the internet and other forums.
If I do have a network interface (I checked this using ifconfig -a) then is there a command to actually make the operating system connect to that network (something like repair on windows)?? Also what is the difference between a network interface with alias eth0 and eth5? I know that when it was eth0 the virtual machine used to connect to the network automatically. Now that it is eth5 it does not! I do not know however if this is related.

At present, I have:
a Netgear router with DHCP off at 192.168.0.1 my computer
eth0 at 192.168.0.2
wlan0 at 192.168.0.2
The wlan0 interface always connects to the router, while the eth0 interface connects to other computers with crossover and acts as a dnsmasq DHCP server for network boot and installation.
If I use the Gnome NetworkManager to enable both connections, that is, with wlan0 connected to the router/internet and eth0 to another computer, both as 192.168.0.2, I cannot access the internet while eth0 is connected.
Why is this? How can I configure my computer to follow wlan0 for Internet usage, but use eth0 for itself (the latter is working but blocking wlan0).

I use DNS on my server as a chasing DNS so its not fully configured. I seem to be having trouble with IPV6 addresses. I'm guessing this is linked to the 6to4 tunnel I have set up to my windows box, but I'm not really sure.
Code:

Using Fedora 10, can anyone tell me how to setup the network scripts to create two network interfaces for vlan x and y. Both interfaces should obtain an ip from dhcp and both interfaces should run over eth0.

I've not found how to configure more than one ip address with network manager.Nor with kde nor with plasmoid network manager.I need several virtual ip addresses for eth0 when the "default" of eth0 is connected i.e. "Connected to Auto eth0" should initialize the virtual interfaces.I have not found no even how to configure the ip address.I think this will be used from ifup config in yast or not?There I have the virtual interfaces but they are not taken from network manager.And last but no least: Is it possible that when using network manager the eth0 is enabled even no user has logged in?

I'm running ubuntu 9.10, the box has 2 network interfaces. I've got rsyslogd running on this box also. On one of the interfaces I have a VoIP ATA which I've configured to send syslog messages to the ubuntu box, however they're not coming up in the log file (I've configured syslogd.conf to capture logs for local2.debug and local3.debug).
rsyslogd seems to be working ok for data coming through on the other interface, but not this one. I've verified the ATA is sending data by using tcpdump and have confirmed it's using local2.debug and local3.debug. It seems perhaps it might not be listening on all interfaces? rsyslog is running with the -c4 switch.

Version 10.04 LTS. Installed desktop version and network worked but I needed a static IP address and the install configures for a DHCP configured address. I tried changing to static address using the System->Preferences->Network Connections application but was unable to get the system to come up with the network up.
So I manually modified the /etc/network/interfaces and the /etc/resolv.conf files. I restart the system but when I do an ifconfig, I don't see a configured IP address on eth0 (only the loopback address). If I run /sbin/ifup eth0 everything then works fine and ifconfig shows the correct address bound to eth0.
My files are as follows:

On my desktop having a NIC 3Com, connected to the company intranet and correctly working, I have added a second NIC ( Realtek RTL-8139) to connect a second small network ( three devices, instrumentation) using static addressing.The new board seems to be rekognized by Ubuntu, indicating "auto eth1" in the Network connections dialog. When I try to configure the connection, the "Apply" button is always disabled, therefore I cannot activate it. The command lspci shows that the board has been recognized but when i sent the
lshw -c network
the response is:
*-network:0 DISABLED

I have a weird issue that I have not seen on any forum. My jaunty on DELL studio laptop seems connected to net, but I can not access any network service (ssh, firefox etc.). But when I connect a cable the cable lights blink as it should be and in wireless connection my wifi light blinks.
It was working 2 days ago without problem, and I have not done big changes recently.I removed and reinstalled network-manager and network-manager-gnome. Nothing changed. I see a message in each restart as follows (when Openafs is starting). I can reproduce it with "/etc/init.d/openafs-client restart"
Code:
ADVISEADDR:error in specifying interfaces: no existing ip interfaces found
#lspci
Code:

For my router I need to change Ubuntu server from DHCP to static IP. So to do this I entered: Code: sudo vi /etc/network/interfaces ...and pushed the wrong buttons and exited the session suddenly by mistake. After learning how to use the vi editor I went back but I got a notice that the the last session didn't close properly and that a "swap" file had been created. Anyway, I entered my static IP info, saved the file, and attempted to restart with:
Code: sudo /etc/init.d/networking restart Restart failed and I got a notice that I should delete the /etc/network/interfaces.swp file so I did. Tried to restart again and, didn't get the .swp file conflict message this time, but failed again - this time I got the following message:

I am currently trying to set up two network interfaces in my laptop. The wireless connection wlan0 works fine and it's the one that I use to connect the internet. It's in the range of 192.168.0.x/24 (gateway: 192.168.0.1). The wired interface eth0 is connect to another router (gateway: 10.0.0.13 with IPs in the range of 10.0.0.x/24. The router is set up to work as an AP and the 10.0.0.x network will only be used to control a robot, so no internet access will be required in this network. The problem is that when I have both connections up, I can't access the Internet anymore. I can still ping both routers, I can enter both routers configuration pages but I can't connect to the Internet. If I unplug the network cable, Internet gets accessible again.
I'm still a novice in linux and I can't figure out how to fix this. I don't want to get into static ip for the wireless connection since I'm constantly using the laptop in different places. The objective is to use the 10.0.0.x router to have a development platform for the robot that can be used anywhere without having to reconfigure the robot for a new network, which is a real pain.
In detail, the laptop connects via wireless to the network with intenet (192.168.0.x) and also connects via cable to another wireless router(10.0.0.x). The wireless connection of the second router is used to connect to the robot. Since I can ping both routers when they're both connected, I think it may be something related to the ip routes. I'm using Ubuntu 9.10 with kernel 2.6.31-17-generic
