Ubuntu Networking :: Set A Permanent IP Address For Eth0?
Feb 28, 2011
The IP address I want for the gateway computer is 192.168.1.100 As I have 'sharing' enabled in Network manager, there is no provision there to specify the IP address for eth0. That is, cannot manually set it there. Every time I boot up, the IP address changes to
i install kernel rpm after i boot that kernel network not working kernel name : kernel-rt-trace-22.214.171.124-132.el5.centos.i686 [URL] error "Bringing up interface eth0: Device eth0 has different MAC address than expected, ignoring."
Since my upgrade to 10.04 I can't use my eth0 wired connection.The wireless works fine.I have tried auto eth0 in network connections set to manual and dhcp. eth0 shows up in ifconfig but no address is assigned.
I downloaded Fedora 10 32bit and put it on a Dell Dimension 8200 to save it from the recycle bin. Everything seems to work except I cannot get an IP addr. Roadrunner is my ISP using a cable modem and a Linksys Instant Broadband Series Etherfast Cable/DSL router model BEFSR41. In system-config-network, the nic shows inactive. If I activate it a window opens saying "determining IP information for eth0". After a short time the message adds the word "failed". Using a Windows PC on the same network, I can look at the DHCP connections on the Linksys and I see the MAC addr for the PC running Fedora.
From the OS installation, /etc/sysconfig/networking/devices/ifcfg-eth0 has following: DEVICE=eth0 HWADDR=00:80:ad:d1:88:c9 ONBOOT=yes
I would like to configure the eth0 manually. I can configure the ip address and sub-netmask but the system can't hold my gateway ip address (I added). It will keep it 0.0.0.0. I have no problem when I getting IP address from DHCP server.
i know exactly what i need to do, im just not familiar enough with command line to do it properly.i have 7 computers.the first 4 are connected to a router via wireless at one end of the house. of the last 3 only 1 will be able to access the router via wireless, so it needs to share it's one wireless connection via ethernet. this computer i'm going to call 'server'server will have two IP'swlan0 192.168.1.6 this connects to the router that has internet access.eth0 i intend to have the following settingsip:192.168.0.1sub: 255.255.0eth0 will connect to a second router, where the cat5 cable goes from the server, into the internet port of the router where i will define the router's static IP:IP: 192.168.0.100sub: 255.255.255.0gateway 192.168.0.1i have then set the router IP for LAN handling as 192.168.27.1 and all ethernet connections will have a 192.168.27.x IP.
so i need to know how to, without a gui application, use the terminal to assign server eth0 a proper IP address, and tell the server to take the connection it has and share it through eth0 to supply internet for the last 2 computers via ethernet.i had it set up in this way with a windows machine being the one that had the wifi access, but i'd rather have it setup for the ubuntu server to do this task. security is imperative for these 3 remaining machines, so just getting 2 more wifi adapters for a connection to the initial router isn't an option.the 2 that connect to server do so through SSH and though server IS connected via wireless it only makes outward connections through
I am trying to get networking up on an old PII which I have successfully installed with FC4. There is a link and activity on the onboard interface because I see the indicator lights. The controller is a 3Com PCI 3c905 Boomerang 100baseTx @ 0xdc80.The only message returned by dmesg about eth0 is "Dropping NETIF_F_SG since no checksum feature."The driver module, 3c59x, is loaded as well as the mii module that depends on it.There is something about "unknown parameter`irq'" in the dmesg text regarding the driver.I noticed that eth0 is sharing an IRQ with the UHCI Host Controller.That should not be a problem, but it should not be necessary. And I could do away with USB if this is a conflict and that is the easiest way to solve it.When I drop to console at runlevel 3, and call dhclient, which is installed, I get a message telling me there is no reply to the dhcp request.I don't think the problem is on the router/switch side.
Everything worked fine until very recently, and without apparently ANY change to the settings on the server, a secondary IP that was assigned to my server won't work anymore..Any IP attached to the same server works fine.. So in my case, the problematic IP is 126.96.36.199. The other IP (188.8.131.52) works without any problem.How would I go about troubleshooting this?
ifconfig: eth0 Link encap:Ethernet HWaddr 00:26:B9:44:11:3A inet addr:184.108.40.206 Bcast:220.127.116.11 Mask:255.255.255.128 inet6 addr: fe80::226:b9ff:fe44:113a/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
I added an init script numbered just before bind9 starts, which needs to see the ipv6 link-local address on eth0. Sometimes this address is not configured, yet. In all cases it eventually is configured.
I am unable to find any script that is configuring the ipv6 link-local address (which is in part based on the MAC address). Does anyone know if there is some script or program that is supposed to be doing this, or is it an internal kernel function?
One workaround I am considering is making this init script go into a loop around sleep 1 to keep checking for the ipv6 address. But I'm concerned this might cause some problems. Any suggestions? I don't want to let it move on to start bind9 until the configuration this script does (more ipv6 addresses) is done.
This is on Ubuntu 9.10 server (for which there is not a prefix choice).
I'm having an issue configuring eth0. I'm using ubuntu 8.10 in a virtual machine (VirtualBox). The correct adapter is being used and it has worked in the past. I've tried placing eth0 in dhcp through the GUI and bash, but always get a 169 address or 127.
5.10 Breezy configured as machine controller. Works great eth0 is a fixed IP to communicate with controller comms board. Not easy at all to alter - the comms board is hard coded to listen on eth0 for commands.
I can use eth1 as the default gateway and ping google.com, etc. But when I now attempt to communicate with the controller with netcat, e.g.
Code: echo !HH | nc 192.168.1.6 80
I obviously never get an answer since the request is passed via eth1. Using the -g option with netcat doesn't work either. I had a look at iptables but it doesn't seem to be able to do what I want. How I can still use eth0 as my communication port to the controller whilst eth1 is the default gateway?
I have two servers on a vlan at my datacentre/colocation and previously both servers had public IPs on their eth0 interfaces. The servers are HP ProLiant DL360s - one is a G4 and one is a G5 The newer G5 is now the LAMP server and the G4 has been retired and I want to repurpose it as an iSCSI target using openfiler freenas or similar.
My G5 has public/static IPs lashed to the eth0 physical interface and the eth1 is not configured to do anything yet. The G4 will have both interfaces available - perhaps one for ssh access from one of my static public IPs and the other to be a private IP on the local vlan. Here is what I am trying to get my head around...
The G5 eth0 - Public IP - full LAMP services on two or three virtual interfaces eth1 - Private IP 192.168.0.1 The G4 eth0 - Public IP for ssh eth1 - Private IP 192.168.0.2
Because my traffic between eth1 on these boxes is via private IPs on the local private vlan it doesn't add to my quota for bandwidth. How do I go about configuring the routing and gateways and other aspects of this so that I can run a private IP space network between the eth1s and still serve the outside world from the eth0s...
I am afraid that if I assign the private IPs to the eth1 interfaces the routing may either not work or interfere with the access to the production internet facing interfaces (eth0s).
Just Installed Fedora 10 on Dell PowerEdge 2950. Installation went fine. Problem is I cannot Assign a Ip address to eth0. Service "NetworkManager " dies on its own "ifconfig eth0 192168.0.8/24" works though.
I want to set my desktop IP address to always be 192.168.1.2. The NetworkManager connects to the network automatically and the IP address is assigned randomly. I can set up another connection in NetworkManager and always change over. But is there any way to make the default eth0 interface to be permanently set to a certain address (using NetworkManager, not ifup)?
I am trying to perform VM cloning using KVM in a centos 5.6 machines. I copy the memory contents of a running vm to an external state file and try to use that to start another VM in a different machine. While starting the cloned VM I provide a different mac address but once it resumes it has the old one . I tried changing the mac address in ifcfg-eth0 but I get the error: Device eth0 has a mac address xx:xx instead of configured xx:xx.Ignoring .
Is there some way to change the ip/mac of the cloned vm without the need to restart the VM ( Then the purpose of cloning will be defeated). Thanks a lot for the info.
I'm running a dual boot Ubuntu 10.04/Backtrack 4 (Ubuntu 8.10) system. I can get internet in the BT4 side but not in the Lucid side. In Lucid I can ping my router, and the network manager says I'm good to go, but I can't get to any web sites. It all started when I tried to put my laptop on another network by mimicking the settings of a computer I had just unplugged from the network. MAC address and all.
eth0 Link encap:Ethernet HWaddr 00:1f:16:ba:4c:8c inet addr:10.136.9.147 Bcast:10.136.9.159 Mask:255.255.255.240 inet6 addr: fe80::21f:16ff:feba:4c8c/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
I have trouble getting a gateway to the internet when setting eth0 with a fixed IP address. The gateway address (192.168.2.1 my modem/router) resets to 0.0.0.0 whenever I apply the changes. DHCP works fine but I need a fixed address for my server.
I try to generate a server client code. What i try to do is sending video streams from eth0 and eth1 to the other server programs' eth0 and eth1. In order to do that, i decided to use SO_BINDTODEVICE. But the code is not working. Am i misunderstood the usage of SO_BINDTODEVICE.

I am running Ubuntu 10.10 on a Toshiba Satellite laptop and need to be able to put a permanent link to my other machine (Windows Vista) on the desktop. At the moment I have to go through the Places - Network - Windows - Network Name - Windows Shares - User rigmarole.
I have sent the last 5 hours (it is now 6am) and I am in no mood for lazy know-it-all'sI have returned begging and crawling back to Ubuntu (I waited a day for 10.10 to be released) and I have again stumbled across why I go back to Micro$oft's Windows.All I want to do it have a permanent share to my nas, which is on my Netgear DGND3300.I can reach it by Place -> Network -> Windows Network -> NAKALEEN -> NAS -> USB_Storagebut for the life of me I can't make it permanent. I need it as all my Movies/TV/eBooks are on this.I have followed every and I mean EVERY option I have found on Google with no luck. From the fstab/mount option to the gvfs option (as you can guess both failed)The reason it is *$&^%$^&%$ me off it that Windows can do it with a couple of mouse presses (Map Network drive). Making Ubuntu a joke in this area.
I have successfully setup a connection from Ubuntu 10.10 to Windows XP Pro via rDesktop, which of course was quite easy, but I intend to do permanently setup via my computers on the same connection. Like KVM switch, but what kind of risks or problems could come up? What kind of tweaks could I apply to add extra security? I would like to do a ssh connection between them, but I have had major issues with it in the past. What kind of options do I have?
which in the past has mounted the windows share without any problems.For some reason this doesn't work anymore. The .smbcredentials file is in the same place it has been since it was created. I have verified that .smbcredentils is in the correct place.In order to find out what the problem might be, I tried
dmesg | tail
and got the following response
[ 18.428245] type=1503 audit(1272697118.037:15): operation="capable" pid=1249 parent=1245 profile="/usr/sbin/cupsd" name="sys_admin" [ 18.432914] usb 1-1: usbfs: interface 0 claimed by usblp while 'usb' sets config #1 [ 19.516273] CIFS VFS: No username specified
I can't pretend that I understand the full message, but it seems to say that it can't find/read the .smbcredentials file and as a result can't mount the share. When I change the code to
where xxxx is my username and password, the share mounts without any problems.I can't work out what I am doing wrong. Has the code changed? For obvious security reasons I don't want to place the username and password in the fstab file where everyone can see it.
Currently my OS is Ubuntu 9.04 Jaunty Jackalope Desktop OS and my web server is Apache2. I have a public address 60.x.y.z and my pc local address is 10.x.y.z. I have a web app in my Apache2 which currently run in localhost(10.x.y.z).
I would like to enable the web app so that it could be browse from outside. I know there maybe some port forwarding process and some commands involved in order to do that. But I have no idea on the steps to do that.
My Fedora 10 install runs from a single PC, from a single location. I'd like the connection, via wireless, to automatically connect to my home network. Right now, I suspect that NetManager scans all the options first.But that's a waste of time. How do I set things up to skip all that and just grab the only connection that will work?I have NetManager set up to "Auto linksys" with MTU set for "automatic" too. I've Googled around for this, but maybe have missed something. Too often, at login I do NOT connect though the network is available. I suspect there's a way to lock this in that I have not yet discovered...
