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
[Code]....
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.
View 2 Replies View RelatedI'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

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.
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.

My network interaces stop working after 5-10 minutes of operation. I have 2 network cards, one static IP and the other dhcp. Sometimes I can ping my router, other times I can't.

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 followed several guides and am trying to get NFS working on my local network. For starters, I think I should be able to NFS mount a drive on the server (192.168.1.65) TO the server. From there I'll work with another client (currently 192.168.1.80)
Code:
$cat /etc/exports
/media 192.168.1.0/24(rw,no_subtree_check)
$cat /etc/hosts.deny
portmap mountd nfsd statd lockd rquotad : ALL

The guides I've read seem simple, so I must be missing something easy. Can't figure it out, so I'm looking for help after googling for 2 hours.
so i just downloaded Ubuntu Server 10.04 and i'm very happy with it on my virtual machine... but when i try to install it on my actual server it fails.
When i went to install it, it told me that there was no network hardware detected or something like that. So i just thought i could install a driver for it later.
So other than that all went well. and im very happy but now i dont know how to install my network driver. The card is a LYNKSYS LNE100TX. i downloaded the driver software and burnt it to disk because i was out of floppys. (I like floppys better) and when i went to install the software it allmost worked but it said:
Code:
make: gcc command not found
I'm assuming that means i need to install gcc but didn't really know how to go about it having no internet.
When I run cat /etc/network/interfaces in Ubuntu 11.04 I get the below output.
auto lo
iface lo inet loopback
I don't see the eth0 or eth1 interfaces, but I am able to see them in the Network Tools application. How do I configure the eth0 and eth1 from command line?
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"

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

i edit this file... Code: /etc/network/interfaces now it looks like that
Code: auto eth0 iface eth0 inet dhcp after the change I cant enter to local host with the browser and unable to log to PHPMYADMIN what i need to change to solve it?
I'm trying to configure /etc/network/interfaces to log whenever an interfaces goes up or down into a file, using this format: UP/DOWN [DD-MM-YY/HH:MM:SS]
How exactly do I use commands with the UP and DOWN directives?
So far as my knowledge goes, /etc/network/interfaces is supposed to contain a list of all the available interfaces. But my /etc/network/interfaces looks like this,auto loiface lo inet loopbackBut I have a perfectly working eth0 connection. Why does not it appear here?
View 9 Replies View RelatedI accidentally killed the dhclient processes. I am unable to access the Internet wirelessly or with Ethernet. It's a little irritating because now I have to post this using my phone. I'm looking for a way to reformat the network files to how they looked when I first installed ubuntu. I don't know quite what these are, or really anything about it.
The /etc/network/interfaces file has the following information:
I'm pretty sure there's supposed to be more.
iwconfig typed into the terminal gives me this:
According to lshw, the logical name for my Ethernet interface is eth1. I think it used to be eth0. It's an 88E8055 PCI-E Gigabit Ethernet Controller.
The wireless interface has logical name wlan1. I think this used to be wlan0. It's a PRO/Wireless 3945ABG [Golan] Network Connection. The driver is iwl3945 - [phy0]
I'm trying to configure OpenSuSE 11.2 with Open vSwitch, and I'm having trouble getting various interfaces to come up automatically when I have bootmode set to "none." startmode is set to auto (or on - tried both), and bootmode set to none, with no IP address assigned in the file. At boot time, I get the message that it's bringing up eth0, for example, but when I log in and check, the interface is not up. Also, if I try "ifup eth0", I get the following output:
xen-users:~ # ifup eth0
eth0 device: Intel Corporation 82566DM-2 Gigabit Network Connection (rev 02)
but the interface is not brought up. why SuSE is saying that it's bringing up the interface successfully, but is actually not bringing it up?
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

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.
DSL modem is a Speedstream 6520 router. All computers work fine via dhcp. I'm trying to setup a small server (print server, ssh & ftp servers). I understand enough of the software part of things to get it going, my problem is setting a static IP on the server box. Every time I set the IP in the /etc/network/interfaces file and reboot, I have no network connection. I can talk to the modem through the browser, but nothing beyond that, not even local computers.
/etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.254.202
network 192.168.254.0
netmask 255.255.255.0
gateway 192.168.254.254
ifconfig shows the .202 address, but box can't get to the outside world, and can't ssh into the box from a computer sitting next to it. If I let it dhcp, then I can ssh into it, and have access to the internet. In the modem, I have dmz set for that address. Wan address is static. I can ssh into it if I let it do dhcp, so I know it can work that far. But if I set static ip, I might as well pull the network cable. I've been beating my head on this for over a week, and I'm lost why I can't get it to work. I even changed the dhcp range on the modem, so the .202 is not in that range. There is no dhcp client installed that I can find. I'm using WattOS beta3, which is a light distro based on 9.04. The computer is an old Dell GX150, integrated nic. I have done ifdown and ifup eth0, still no happiness. Doesn't seem like it should be that hard, but I'm stumped. DMZ should let everything pass, so don't need to mess with port forwarding and such. I know it works using dhcp.
I am trying to preseed the UBUNTU 9.04 x86 installer and everything else is okay except that for some systems, it says "No Network Interfaces found" with options as "Continue" and "Go Back". My network interface detection is set to "auto" in my preseed file. I want to remove this popup. Can someone please help with the correct line in preseed.cfg?

View 2 Replies View RelatedWhen I boot into Ubuntu with the Xfce desktop then proceed to terminal to check my IP it is always some random IP as provided via DHCP by the router. If I then go to the cmdline and type sudo /etc/init.d/networking restart then the wifi correctly connects to the router to the one static network address that I have specifically provided for it - as stated in my interfaces file. Why is this not happening on startup?
