I have a server with two NICs. I tried to bond their network interfaces together, but it bombed out and didn't work, despite the fact I copied the example 100% except for my own numbers for addresses, etc. I decided to go back to a single NIC and let the other unused for now, since I need to get this server running. uh. yesterday.
[Code]...
When I boot up, often times eth0 isn't listed in ifconfig. I'll see eth1, which is just an unused interface at the moment, but eth0 is no where to be found. If I restart the network service, bam. I'm good. Why is it not auto coming up?
Sometimes (but not every time), when booting my Dell Inspiron 530, eth0 will not come up right away. I can boot and log in to Gnome, and the NetworkManager applet shows that the ethernet cable is unplugged. After sitting for 5-10 minutes, it will link up and everything works. If I unplug the network cable and plug it back in, it comes right up. But once it's linked, it works fine and never disconnects after that. I've tried switching to a different port on my switch and a new ethernet cable. So I suspect it's some sort of weird kernel problem. I checked /var/log/messages and the only thing that looks weird is:

[Code].....
But I have a second Inspiron 530 that has the same entry and it works fine. Has anybody seen a problem like this? I've looked around and so far can't find out the exact issue. I've upgraded NetworkManager to the latest version for FC10
I installed Fedora 12 on an Eee PC 1001HA. This laptop has a Ralink RT3070 wireless chipset, for which the driver is not yet in the kernel (still in staging I believe). However I downloaded the driver, compiled it, and installed it. AFAICT, it works fine.
One small obstacle remains: I am uable to get the network interface to come up automatically; I have to run # ifconfig ra0 up. Because of this NetworkManager never sees the wireless interface, making connecting to WAPs a chore.
I created a ifconf-ra0 file in /etc/sysconfig/network-scripts, and it includes the line ONBOOT=yes, but this doesn't do the trick.
I'm using testing/Wheezy 64 bit: after upgrading to the latest repository kernel (2.6.38-2-amd64) my WLAN card isn't showing up unless I do a "modprobe brcm80211" or add " brcm80211" to /etc/modules.
now my system does not connects automatically when fedora start's to eth0 i have to connect it manually by pull down menu in the beginning hostnname was dbe272b22.dslam-172-17-161-245-0532-474.dsl.cantv.net i do not remember if the last part ".cantv.net" was there.... i changed hostname "dbe272b22.dslam-172-17-161-245-0532-474.dsl" maybe ending with ".cantv.net" with system-config-network for hostname "edicta" i modified /etc/hosts by hand twice, now do not remember what i did exacly but here you can see /etc/hosts
i have uninstalled and reinstalled alsa and made sure its not muted, in pulse audio it displays sound is coming out when i play a song, but no sound is actually coming out.. i dont want to go back to windows, but if i cant get sound im going to have to
If I uncheck and recheck "Enable Networking" in the Network Manager Applet 0.7.996 I would expect the wired network to disconnect (which it does) and reconnect (which it does NOT). So I tried sudo ifdown eth0 and got
Quote:
Ignoring unknown interface eth0=eth0.
ifconfig tells me

so I am at a loss. How do I stop and restart the network interface short of rebooting the machine?
My network name is eth2 it was changed by some reason and now i got these errors... i installed, reinstalled, re re installed, tried to run the asistant but no luck :/
Code:

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).
I got two IP's in my dedicated server. Both are external IP's. I would like to make connections using 2nd IP address under eth0:0 interface. For example: when using "lynx whatismyip.com" should display my 2nd IP. How to do this using iptables ?
On my machine (Desktop PC) I have 2 network card : wireless (rt61 802.11) and a wired card (BCM44). When I install debian 5.
The wired card is detected and logical name eth0 is assigned, while wireless is not assigned I install firmeware* software to configure the card. It is done in some way ( I used mnetwork from mepis, it works fine).
Now the problem: eth0 disapears, and no eth0 inteface found? ifconfig gives just wlan0.
Question: Why there is no eth0, it was before configuration of wlan0 ?
How to active again eth0, or ho to create the logical eth0?
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.
ifconfig eth0:
Code:
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'm not sure how long ago this happened but eth0 seems to have vanished from my computer. wlan0 works fine and when I plug into the switch there is carrier detect.

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 having trouble getting grub to automatically boot into ubuntu server. When I turn on my server the grub menu shows up and shows me the choices. They all work fine except that grub wont automatically select one. This wouldn't be too much of a problem but this is a headless server and I can't boot into ubuntu without a keyboard. I tried looking through the grub 2 documentation but nothing seemed to work when I edited the conf file.
I've looked today on my logs /var/log/message and I find device eth0 entered promiscuous mode I don't remember putting eth0 in promiscuous mode I'm connected to the net thru a router how do i turn that off ?
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.

from my thread here:URL...It looks like i'm getting libglib from one of the PPA's I've added. How can i tell which PPA its coming from and get it from official instead?
how do i fix my sound problem. i'v just installed ubuntu 9.10 (karmic koala), but once i went to videos i clicked on a video to watch after i installed flash. but any video i try to play, they all come out with no sound what do i do?
I built a HTPC using Zotac ION ITX A 330 (has an onboard Atheros AR9285 according to lspci) and the plan was to connect this to my Netgear WNR2000 using WiFi. The OS is Ubuntu 10.04. I can connect to the router fine. Signal strength stable between 65-72% so this shouldn't be an issue (other hardware including two laptops running Vista (DELL XPS) and OSX (MBP) connect just fine at the same location). I stay connected for everything between five to 60 minutes then i lose the connection. According to the syslog i get deauthenticated due to reason 2. I've tried the backport modules.I've also tried wicd instead of the standard gnome Network manager. No difference.
I am not a programmer. I am a common man. Recently I bought a latest compaq laptop with intel core i3, 2gb ram, 250gb hard disk. As sound was not coming without earphones I tried steps mentioned in [URL].. following supported in ubuntu latest version? I downloaded and installed ubuntu from [URL]..yesterday

Just installed Ubuntu on my dad's computer, now all I hear from the speakers is static.
I have had to use the liveCD to edit grub and then Chroot and update-grub (don't think that matters, but just throwing it out there.)
Speakers had static on liveCD, as the OS booted up (it tried to play the Ubuntu logon sound) but after it got logged in, it did great!) Now it won't work at all, I can make out that someone is talking, but not what they are saying Aesop's Fables in Examples folder.
I'm using Harmon/Kardon soundsticks and it looks like my settings are all in order to get sound through Firefox but it doesn't happen. I only get sound through Rhythm Box?
