Ubuntu Networking :: Wired Network - Missing Packages / Bad Config
Apr 24, 2011
I'm having problems with networking. I just installed Debian 6 SServer LAMP and it didn't autoconnect to internet. I plug in the internet to my eth0 (default) port, and I keep getting timeouts. I found that dhcp3-client was not installed and fixed that. My etc interfaces has this for eth0: Auto eth0 Iface eth0 inet dhcp What other packages or config do I need to make the internet work? It's missing something basic that wasn't setup properly. I do get the correct dns address to my isp provider when I check etc resolv.conf. It just can't dhcp discover.

I looked around, but found no results that really matched and I would like to point out that I am fairly new to linux, so this may be a very obvious answer to some of you.I am running fc12.i686, installed from a disk in the back of a book for a class. No one else in my class is having this issue.When I select System > Administration > Network I am given this error: Failed to execute child process "/usr/bin/system-config-network" (No such file or directory). I am not so new to not realize that this file is not there, which I confirmed with an "ls -a". My question is, is there any way that I can download and install that bin? Or perhaps replace/repair it with the disc? It was supposed to be in the original install and my have been, the only thing that I have done in the /usr/bin/ directory is I tried to install Java (6.22 I think it was), which told me it installed correctly but didn't work when I tried Minecraft.

entries for connecting to broadband. Was OK with ubuntu 8.04 which had boxes for DNS server, etc. The 10.04 asks for MAC address (?) and there is a space for "DHCP client ID". I don't understand these terms. how I may proceed, especially exact syntax for any command line work. I am in Chennai/Madras, and have a BSNL wired broadband connection to my Dell laptop.

I bought Sony vivo c series laptop and I tried to install ubuntu 10.10 version on it.After installed ubuntu the ethernet device was not activated. But It's working fine with wireless network. Similar problem I faced with older version 10.04 also.
Then, I tried with newer version 11.04. It detected Ethernet device.After installation over I just rebooted and I have chosen ubuntu OS, then it stuck and goes to blank screen.I am doing all my work in ubuntu only, i am struggling to recover form this problem for a long time.

I'm having network problems and I have no idea how to fix it. At first, my internet connection was suffering on all computers on my network (Mac, Windows and Ubuntu 11,04). So, I disconnected my cable-modem and then reconnected. Nothing.... So, I rebooted my Windows machine and the internet came back on that computer.
I then went to my Ubuntu computer and clicked on "auto eth0" (per the way I interpreted instructions from the internet). The symbol turned from the "two arrows" to what looks like a wireless, looking for a signal. I thought that maybe I should just reboot, as I did with Windows. However, when I did reboot, that same wireless symbol was there, then a message came up saying:
Code:
Wired Network: You are now disconnected
I can't seem to get my internet connection back on my Ubuntu computer, though it is working on every other computer on my network.

i installed linux at home on my laptop (dv2000, hp). Because i was having problems connecting to the internet through wireless. And wired at friends houses.So installed linux. Wireless took me a while but finally got that working. Now the problem i have is that wired is not working apart from at home. Any other router apart from mine it cannot connect to.

"Need help with entries for connecting to broadband. Was OK with ubuntu 8.04 which had boxes for DNS server, etc. The 10.04 asks for MAC address (?) and there is a space for "DHCP client ID". I don't understand these terms. I will appreciate some step-by-step instruction or example of how I may proceed, especially exact syntax for any command line work. I am in Chennai/Madras, and have a BSNL wired broadband connection to my Dell laptop." I have repeated what I tried in the ubuntu forum without success. I'm really in newbie category, and not comfortable with computer or internet jargon. I can still connect with ubuntu 8.04 and firefox, just once daily. In a later post I also added: In Ubuntu 8.04 there was a system> admin> network tab (missing in 10.04). In the connections tab "wired" was checked. The general tab had my computer name (tsq-laptop) for host, and a blank box for domain name. The DNS tab had 192.168.1.1 in the servers box (presumably my service provider BSNL), and nothing in search domains. The hosts tab had a list of IP addresses and aliases, the first few being:
127.0.0.1 - local host
127.0.1.1 - tsq-laptop
::1 - ip6 local host ip6 loopback
fe00:: - ip6 localnet, .... (and a few more such I think most (or all) of these entries were generated automatically by the system, since I don't understand the jargon at all! I don't recall having any difficulties then, some two years back.Before that I had major problems in using the internal modem for a dial-up connection, but got detailed help by e-mail/internet from some really knowledgeable people in Europe and elsewhere regarding linmodem configuration, which I followed blindly and it worked!
In 10.04 there is only the taskbar icon to edit settings, and it has a different structure. It asks for MAC address (example 00.11.22.33.44.55). Other info required is IPv4 settings, DHCP client ID, about routers and other stuff. There may be other system settings to be made, which I can try with proper guidance. The ubuntu help page gives very sketchy information, and the images are not clear at all. No response to that till second day. Subsequently: In the 'wired' tab the 'routes' button popped a table where I entered address as 127.0.0.1, and netmask as 255.0.0.0, leaving gateway and metric blank. This is all geek stuff for me - I'm an old-fashioned engineer from the slide-rule era!
Should all this have been in the newbie forum? Thanks, =TeeSquare=

I'm having a problem where the wired network wired network (eth0) disconnects when the connection is idle for a while (usually tens of minutes). It works fine every time I boot up, but eventually it dies, and I can't ping the machine, or ping anything from the machine. ifconfig shows that it still has an IP address. Running ifdown/ifup causes it to work again. I intend for this machine to be a server, so I can't afford to go restart it when I need network access. sudo lshw -class network gives me this:

I just installed (dual-boot with Vista) Ubuntu 9.10 in my Toshiba Satellite M300. The problem is that (when using Ubuntu 9.10), its network is dead, both wireless and wired. The LEDs of the LAN port don't even blink. My wifi is not also detected. Both of my wifi device and LAN port are functional when using Vista.

I am running ubuntu 9.10 on a dell xps m1530 laptop dual booting with windows 7. I am trying to achieve the following setup.
Wireless router <=========> Laptop <-----> Switch <-----> PS3
---- wired
==== wireless
Both laptop and ps3 have static ip addresses
The reason for this is I can connect to the internet on my ps3 through my laptop, and I can stream from my laptop to ps3 through wired connection. This works fine in windows 7 all I had to do was right click bridge connections. As I dual boot I don't want to have to make any changes to the settings on the ps3.
My interfaces are:
eth0 - wired
wlan0 - wireless
I installed bridge-utils and created a bridge and added both eth0 and wlan0 to it. However I could not get it to work. I have also tried internet sharing through network manager and firestarter.

I have just installed Ubuntu 10.04 on an HP Pavilion dv6000 series laptop, dual-boot. Everything is working except the networking. It can see wireless networks, and when I type in the password for my wireless network, it tries to connect, then asks for the password again. When I plug in the Ethernet cable, again it tries to connect, but after a few seconds gives up and tells me I am now offline.

I recently upgraded to 10.04 and now my wired network no longer works. I am unsure if it worked at all since the upgrade as that computer is rarely used, but it was definitely working prior to the upgrade. It is some sort of Realtec card, I believe. Does anyone have any suggestions? I'm running 32 bit 10.04 on a 2 GHz P4.

I installed xubunto 10.4 on my pc the other day and every thing was working fine and then the next day my wired network card went down. So I restarted it and it say Wired Network Disconnected. I tried doing sudo ifconfig eht0 up to try and bring the card back online but nothing happens. I also tried reinstalling xubuntu on my computer. Again my internet works then starts freezing up so I restart it and my ethernet card goes down again. I have tried also plugging it into the second ether net port on my computer but that does not seem to work. Also I went into my dhclient-script and went to the bottom to look at my network card stuff.
It reads
#Changed from 'ifconfig $interface inet 0 down' - see Debian bug #144666 ifconfig $interface inet 0
exit_with_hooks 2 "$@"

I use Ubuntu 10.04. Last night, I installed the most recent updates for this istribution, and before I shut off my laptop, my internet was working smoothly. However, today my Internet connection is behaving very strange. When I try to connect to the internet, my browser times out or cannot establish a connection. I'm able to connect to low-input sites like Google search, but I cannot connect to sites like Facebook, Wikipedia, or even the Ubuntu forums (I'm currently using a friend's laptop to post this). Pidgin and Skype work without a problem, as well as Transmission. I primarily use Firefox, but I also tried Chrome, Opera, and Epiphany; none of them worked. Oddly enough, my update manager also cannot connect to the Internet to retrieve updates.
I have restarted my router, but it still works properly, as it is running fine on my friend's laptop. I have tried 'no proxy' in Firefox, but it did not help. I also disabled IPv6 in etc/sysctl.conf by adding the code:
#disable ipv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
[code]....

what is the command to restart the network services? ive forgotten i think it uses -hup switch though. about 1 in 20 boots on my desktop ubuntu system results in the system insisting its no longer on a network yet has a fully functioning network card. a reboot always fixes the issue but that doesnt seem like a long term solution to me. If I ping a neighbouring system I get nothing. (sent packet count increases in ifconfig) If I ping from a neighbouring system back to my desktop I get nothing (no change in packet count) I can bring down and back up the network interface with no results. A sniffer shows the system definitely isnt sending anything out Everything worked previous boot and will work again after a reboot.

I am working on ubuntu 10.10 in a VM. I went ahead and did updated the system when prompted. That has disabled my wired network connection. I am not sure what is the reason. If it is a device driver or any network service. I guess device driver is not an issue as I can detect my network card from ubuntu.
Does any one know the solution?

I just installed Ubuntu 10.04, complete noob, but I can't connect to the internet. I connect the ethernet cable, select auto ethernet and the icon animates for about 30 seconds. But then I get a notification "Wired network Disconnected - you are now offline".
Don't know what other information I should provide. I tried a few things from different posts like editing the dhcpclient.config but don't really know what I'm doing and none of these worked anyways. I'm not even sure if they were solutions to a similar problem! I'm using the same connection on my Mac OS 10.4.11 (different machine) and I have no problems. Could I use these same settiings in Ubuntu? I don't know what the different fields represent or what I should input in manual settings.

when I have a broken packages on the system and want to apt-get install something (completely unrelated to the broken package) apt-get starts giving me crap about the broken stuff and won't download and install the packages I'm asking for. How can I make it ignore the completely unrelated stuff about missing deps on my system and download what I want?

Issue: Using Fedora-14-x86_64-Live-Desktop.iso, I created a live usb and tried it on Dell M6400. I can boot into F14, see the internal hard-drive and other usb drives -- but F14 will not go on the network -- neither wired or wl networks.
I am not sure what additional information I need to provide to help resolve this issue. Perhaps some background info would help?: I am trying to move from XP to linux on the M6400. The latest Ubuntu live CD would not boot, the latest CentOS live CD could not find the internal drive; I got best results with the latest Fedora (and I am more comfortable with the F14 gnome interface than the F14 KDE, the Ubuntu, and the CentOS interfaces). I do not know how to investigate the inability of F14 to detect the ethernet cabled network. I was unsuccessful in my attempts to get the wireless to work: "lspci -nn" shows BCM4322 802.11a/b/g/n 14e4:4326 (rev01). I read [URL]../docs/linux_sta/README.txt and used what I learned in my attempts. Installing broadcom-wl-5.60.48.36-1.fc13.noarch.rpm, kmod-wl-2.6.35.6-48.fc14.x86_64-5.60.48.36-2.fc14.2.x86_64.rpm, and kmod-wl-5.60.48.36-2.fc14.2.x86_64.rpm (found at rpmfusion) did not help. I tried to build and install the sources from http://www.broadcom.com/support/802.11/linux_sta.php; the machines I had for building were 2.6.28-18-generic Ubuntu, fc5, and rhel5 -- attempts with these builds failed too.
