Ubuntu Networking :: Don't Seem To Have All Variables For Eth1 Inet
Apr 28, 2011
I'm having a strange problem. I'm using Ubuntu server 10.04 LTS and I want to setup a system with 2 network interfaces: eth0 and eth1. However eth1 does not come up at boot I have a screenshot of my /etc/network/interfaces file I don't see what is wrong. eth0 gets it's adress from DHCP eth1 gets a static adress. When i try to restart networking it quits with this message "don't seem to be have all the variables for eth1 inet" Can anyone point out what I'm doing wrong? if i do 'sudo ifconfig eth1 192.168.3.1 netmask 255.255.255.0 up' eth1 comes up
I need to setup two ethernets in my Centos box. OK no problem both ethernet and 1 virtual works perfect. eth0, eth1 and eth1:0. I'm trying to set up diferent routes for eth0 and eth1/eth1:0 I need eth0 has a 192.168.1.1 gateway and eth1/eth1:0 192.168.1.100 gateway.I think I've tried almost every thing but always get one gateway for all the eth.These are my config..
/sbin/ifconfig eth0 Link encap:Ethernet HWaddr 00:XX:XX:XX:XX:XX inet addr:192.168.1.168 Bcast:192.168.1.255 Mask:255.255.255.0[code]......
I'd like to use one of the popular USB wireless modems for Internet access. If Linux supports this, I assume that the required driver is in the kernel, and that connection would be automatic. Has anyone had experience with this?
I've been struggeling with this for a few hours now, googleing and so on trying to find an easy way to just switch which device I want as primary for internet connections. After long battles I'm at a loss, this is the current automatic routing
Code: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 85.225.76.0 0.0.0.0 255.255.252.0 U 1 0 0 eth0 85.225.76.0 0.0.0.0 255.255.252.0 U 2 0 0 wlan0
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.
1-Defining two ports 2-Defining two sockets 3-Assigning host ips on them
I have a hardware device with two ethernet ports, eth0 and eth1 running Centos 5. Basically my goal is to forward packets from eth0->eth1 and eth1->eth0 as well as get a copy of these packets for analysis. If I set IP routing to do the forwarding then I won't get a copy of the packets for analysis.
mkvmerge -o <filename without extension>_TV.mkv -S <filename> && mkvextract tracks <filename> 3:<filename without extension>.*** && perl /home/brian/Desktop/ass2srt.pl <filename without extension>.*** && rm <filename without extension>.***
Doing these commands for multiple command line file inputs is the goal. So I can just type ./script.sh *.mkv in my terminal.This is what I have so far, but it doesn't work whatsoever.
I am running Ubuntu10.04 as a Virtual Machine in virtualbox.I changed my Networking settings from NAT to Bridged Adapter and manually assigned IP addressing information for eth0 in /etc/network/interfaces. For some reason doing /etc/init.d/networking restart didn't bring up the network interface. So i replaced the new /etc/network/interfaces file with the original and rebooted. Now I have eth1 in place of eth0. Under System>Preferences>Network Connections I have Auto Ethernet and eth0. However running ifconfig shows lo and eth1.
I'm using comcast, and I setup my server, everything works fine.But later I found out that the server inet address is changing everyday, and it makes my server almost not accessible.Is there anyway to fix that problem??
My wireless suddenly no longer works either in Ubuntu 10.10 or Windows 7. Upon some investigation, I have found that my eth1 is no longer showing up as it used to.
What can I do to get my wireless back?
Right below is some current specs, while below that is an older set of specs from a while ago.

I am working on USB Connectivity between android 2.1 Host and Windows Mobiles 6.1 device...When I connect the windows mobile device to android host through USB (in RNDIS Mode), It is appearing as 'eth1' interface instead of 'usb0' interface. Why 'eth1' instead of 'usb0' ? Does behaviour of 'eth1' is same as 'usb0'?
I have an older laptop, a Toshiba Satellite Pro 6100 that has a switchable internal wireless connection. It will not connect to my router. I am using the 10,04 netbook remix. When I use lshw in terminal this is what I get:
Should it not be identified as wlan0? I know a whole lot about Ubuntu linux because I don't. I did a clean install over XP and am using this laptop as a learning tool for linux in hopes to divorce windows completely.
I have a bit of a "unique" situation here. I have myself plugged into two networks - since we run two networks here at work (long story, we merged and never combined them due to two different companies) and want to block ALL internet access off eth1, and only have it off eth0. I only want traffic from 192.168.67.1-192.168.67.255 allowed on eth1, but everything allowed on eth0. Or is there a way for the internet/applications to be on eth0 instead of eth1? Would I use iptables or something?
im a linux noob dont get techy ill die of brain fry im running a craft bukkit minecraft server on my 11.04 ubuntu server. however the server uses my only 10m Ethernet cable that i normaly use for my ps3 (i will NOT go wireless. i hate it (or dont like it)) therefor i found an old PCI NIC in an old computer, its a 10/100 realtek one. ifconfig detects it (after two commands:
Code: ifconfig eth0 up dhclient eth0 )
now i need to send the internet to my ps3 too.i know the connection wont be blazing fast but isnt it okay?it musnt interrupt the minecraft server. if you need info just ask. ill try and provide them.
I've noticed that when Linux boots on different machines or with different versions, the network card is assigned to eth0 or to eth1, when there is only one network card. What is the difference and is there any way to tell which one it will be for any machine or version?
I often run "gulp", a networking utility, to capture data from an instrument on "eth1". By default gulp must be run as root to have access to the ethernet port, and when I'm the only one running it, that's fine. But I need to let several other users to capture data and don't want to give them all sudo permissions for both gulp, and more importantly, 'chmod'. Is there anyway to change the permissions of eth1 to allow all users to open it and avoid sudo entirely? This is on a Red Hat/Fedora machine.
I want to change eth1 to eth0 and eth0 to eth1, because I have some old firewall script and I need eth0 be eth1, because of routing internet. My ISP close my net connection on MAC adress.
1. I am trying to setup NIC via network not NetworkManager 2. I have assigned the ip to both NIC with #ifconfig eth0 192.168.1.1 3. #Ifconfig shows my nic and ip 4. restart the service network . 5. #ifconfig shows nothing. NO NIC card
I dont want the network manager coz i dont want to install the gui on router and network manager works only in gui mode. ( i think my this understanding is correct)
I tried to configure the NIC with Network Manager
When ever i restart the network service i have no out put from ifconfig
I tried to configure the NIC with #setup command as well and select the dhcp option
I can not find any ifcfg-eth0 in /etc/sysconfig/networking-scripts/
I've got a machine running 9.10 with two network interfaces, one being motherboard based (atl1) and the other in a PCI slot (e100). By default at boot the interfaces come up in the wrong order. I'd prefer to have the e100 come up as eth0 instead of eth1. And then have the atl1 come up on eth1 instead of eth0. Both interfaces use static addresses and IP4 routing should be active across them. Where do I configure things to force the specific settings?
I'm trying to set up my cell so I can use cellular internet in ubuntu like I do in windows. I've scoured the net, and found multiple guides, unfortunately, the problem I'm having seems to precede any of these. I can't follow the guides because I can't get to the first step. When I plug my phone in via USB, whether I'm using the internet sharing program or not, I see "eth1 connected eth1 disconnected" pop up over and over and over.

I have a linux machine with 2 ethernet ports(eth0 and eth1). eth0 is connected to a router which assigns it an IP address 192.168.1.2. eth1 is connected to a switch and I assigned it an IP address 192.168.1.254 using "ifconfig eth1 192.168.1.254 netmask 255.255.255.0 up". How do I ping eth0 from eth1?
I am using ubuntu cli 10.04 for several different computers with different network cards, any time I plug in my persistent usb (ubuntu installed on usb) to computer the network would not work, when I find out what is up I see that it is up on next eth driver, I cant enter up to 50 or 100 or 500 entry there all the time and same thing with wireless since I use radius authentication its even makes it worse.
So to summarize: sudo vi /etc/network interfaces auto eth0 ifup dhcp iface eth0 inet ... ... ... auto eth100 ifup dhcp iface eht100 inet .... How to keep one entry for all those different computers (one for eth0 and one for wlan0)?
Im setting up a server thats connected to a large network. Now my external ip on the network is static and is 10.0.12.15. What I want is to create a dhcp network using the second port of my box. The first port eth0 goes to my network with the static ip 10.0.12.15 and my second port is connected to a switch with the static ip 192.168.12.1. Now dhcp works fine but none of the boxes that are connected to the internal ip cannot connect to the internet. Iv tried using squid and manual static ip routes. Im not using network manager or anything cause its a command line server.
installed UB10.10 on a dell d800 laptop with a built in wireless.The eth1 wireless device/connection shows up on the little radio icon as connected .but the chrome browser says "ERR_name_not_resolved" when I enter a common url.What's the next step or hint for gaining full internet access ?
Once or twice an hour or every few hours the interface will drop off. When this happens and comes back up and ssh sessions I have open will sit there and lag for 15-20 sec while, I assume, the connection is re-established. Any sessions I have open to the mySQL database will be dropped and I'll be given error messages associated with loosing connection to the SQL server. I have run a constant ping against the server and when the interface seems to drop off I'll get 10 or so host unreachable and it'll then start to reply again. This happens with both eth0 and eth1 on this Dell Poweredge 850 running 11.04. I have done a "sudo lspci -v" on both the server acting up and another Natty box that doesn't have this issue but the same hardware. They both are using the same driver versions though it seems certain options are slightly different between the two.

I've checked the cable, it's a pre-made with both ends looking good. I even swapped it out for a fresh home made cable and the problem still persists.
