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?
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 ?

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.

Would have prefered to install it via yum but dont know the magic words to get yum to find it.
I think this might be related to the changes to using udev or DeviceKit. It started when I was running the beta versions of F12. Then it crept into Debian Sid. And my Arch Testing and Gentoo also suffer from the same.
What happens is that I'll be working along. Then when I press any key it is as if the SHIFT key is pressed. When I press CAPSLOCK, some of the keys react as they would normally. This never lasts for more than 5 minutes. And seems to happen infrequently. I say seems because there are the times I am at work and it could be that the same thing is happening only there is no one on the keyboard.
The reason I pick out udev/DeviceKit is that when it used to happen to F12 beta, the other distros had not yet made the move. So back then it was only a F12 issue. Now it is happening across the board. And only started recently.
I have been trying to install Linux on a olsish computer for a long time now, with no luck :[ Everything goes fine until Ubuntu/mint asks me to activate the nvidia drivers. When I do it and restart and login the there is no desktop. The computer has a single core amd athlon 64, 1.5gb's of ram and a nvidia 7300gs card.

Network manager reports this interface as a "wired connection", usb0, using the cdc_ether driver.I also have a router at home, so I can connect my netbook to my desktop wirelessly. My desktop computer connects to the router via ethernet connection, and network manager reports it as eth0.
When I had Ubuntu 8.04 installed on my desktop, I could use my phone, via usb0 interface, to connect to the internet at the same time as using the router on eth0. But now I have 10.04 on the computer, and it won't let me use both interfaces at the same time: I have to unconnect the router before I can use usb0.
I installed F13 on an Acer laptop for a friend who is just beginning with Linux. This laptop has the dreaded Broadcom chipset and is using the b43 driver. When it was first installed, wireless was automatically detected and worked fine. However, as usual, there was about 200MB of updates after the install, and the wireless was downloading extremely slowly, so I connected eth0 just to complete the updates. Ever since, the wireless will not work. When the machine is booted, wireless is shown as disabled in Network Manager. I remembered that there was a wireless switch on the front of the laptop and switching it on allows me to check the enable wireless box, but wireless says device not ready.
ifconfig wlan0 up returns:
Code:
SIOCSFFLAGS: Operation not possible due to RF-kill
I assumed this meant that the switch was in OFF position, but it is not. iwconfig shows the wireless is detected. It appears that there is a script for rf_kill somewhere in the filesystem that is keeping this from working.
I've got a vmware install of Fedora 12 running as a server. This install has the /etc/sysconfig/network-scripts/ifcfg-eth0 file configured with the proper info and the service has been restarted. When I run ifconfig I only get the loopback interface, when I run ifconfig -a I can get the eth0, but without the pre-configured ip address. When I enter ifconfig eth0 up I can activate the interface, but without the afore mentioned ip address. I need to be able to yum ssh, install it, and run it with rsa keys. Can do none of this without an interface obviously.

connection is set to connect automatically using dhcp... used to work, after a latest updates basically stopped working.
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).
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 :/

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.

Installed a TP-Link TG-3269 Gigabit card in a machine running OS 11.3 32 bit, when I go into Yast, Network Devices, Network to try configuring the card I get this errormsg: Unable to configure the network card because the kernel device (eth0, wlan0) is not present. This is mostly caused by missing firmware (for wlan devices). See dmesg output for details. Couldn't find any mention of the card in dmesg's output, (though the 8139 onboard card is in there) there is some stuff about pci host bridge but I don't know whether they would be relevant or not
The chip on the card says it's rtl8169sc but lspci lists it as being 00:07.0 Ethernet controller: Realtek Semiconductor Co., Ltd. Device 8369 (rev 10) Done some googling and there don't seem be any drivers for a Realtek 8639 and it returns no matches from a search on realtek's site, but there is a driver there for rtl8169sc chips, which I downloaded and installed, no errors when installing it Even after a reboot I still get the same error in Yast's Network Settings screen, lspci still lists it as 8369 and the device isn't listed at all if I run ifconfig

I finally got everything installed and then slackware setup prompted me to reboot. then i did and it just took me back to windowsxpx64. so then i tried booting off my usb, and it worked, however when i login as root, i just get the bash commandline and not interface or programs or anything. i cannot login as any other user and the setup did not prompt me to make another user account. so how would i activate lilo or make it so i can boot with it to slackware? i rather use grub but for now i would just like to get slackware working right.
View 2 Replies View RelatedI just installed debian Jessie (8) and find that the system cannot resolve URLs. Checking with the "hosts" command confirms this. I am connected to a comcast network in my house. I have looked over some of the documentation and it seems like there are several conflicting ways of setting up the resolver. It is not clear if the install process did this for me. I am assuming that DHCP was installed as the computer had no problem defining IPs for its wlan0 and eth0 ports and I can telnet in from and in-network PC. I have a few questions :
1) I see /sbin/dhclient/,,,,, running so i assume this is the DHCP deamon in use?
2) Before I dig too deep I wonder if an internal firewall is involved. Is there a command to shut it down temporarily?
3) what would I look for to determine if a resolver was installed and which one?
I see from my windows machine an apparent comcast DNS server but I don't believe I can code it into resolv.conf on debian as the OS now overwrites this(I already tried and failed!).
Since the last update of xorg/x-server I am receiving following error after logging into my gnome desktop:

According to some google-results it has something to do with the gnome settings not being the same as the X-server settings.

How do I activate networking? (I am currently logged in from Ubuntu on another computer). I installed Debian Squeeze on an iMac 7.1 (which works perfectly well with ubuntu) from the netinstall CD (today's daily build), and of course I deactivated root login, coming from ubuntu. Now I find I have to enter my root password (login password will not do) to activate networking! Is this a joke? I had the network configured with DHCP during install! So how do I activate the root account, or, more to the point, how do I get by in Debian without activating root login?
View 5 Replies View RelatedWhen I boot fc14 with an already defined printer connected on the parallel port, then I can use the printer. The printer appears on parallel:/dev/lp0. But, if the printer is not connected during startup, when I connect the printer I cannot use it. Nothing happens. I have no corresponding message using "dmesg" command when I connect the printer.
I cannot make cups see that the printer is connected, using "localhost:631" in firefox. Is it possible to "mount" the printer manually? Using "system-config-printer", the printer has to be "activated", even though it is not used or even connected. Then "parport" module is installed during boot (with other related modules: "ppdev" and "parport_pc").
Then, when the printer is connected, "dmesg" shows :
lp0: using parport0 (interrupt-driven).
lp0: console ready
And, of course, it is now OK to use the printer.
