Fedora :: FC12 - DHClient Breaks My Internet Connection
Mar 17, 2010
Latest FC12 update included dhclient-4.1.1-9.fc12 which fails to configure eth0 after restarting the computer. Had to remove/downgrade to 4.1.0* (and reinstall dracut and NetworkManager(-glib)). There is no config file in /etc/dhcp/dhclient.d so I don't know how to reset dhcp/eth0 to connect. Thought some one smarter than me might have noticed this by now and worked out a solution. Can't tell that anything in Bugzilla sounds like my problem. Might only be x86_64 or KDE-4.4 problem as my 32-bit Gnome install is not affected. Easy enough to grab the rpms, just annoying. Still haven't learned how to keep a package at version x.x with Fedora yet but that's another topic.
Running 10.04. For some reason, starting today, I have no internet connection unless I run this command in terminal - sudo dhclient eth0. I have a hard wired ethernet connection on a Desktop PC with a static IP address (there are a number of devices in the house) and it has been running 100% for months and months. Why suddenly do I have to enter this command to get connection? When I switch on I get a connection in that when I click on the Top Panel icon and right click Connection Information it tells me I have an active connection to my router on the normal IP address. I cannot ping the router and Firefox says Server not found. After sudo dhclient eth0 everything works - what has happened since yesterday evening and this morning to stop what has been 100% for months?
kernel-2.6.32.10-90.fc12 seems to break 802.11n with my intel 4965 chip on my thinkpad t61p. Anyone else seeing the same thing? iwconfig shows extremely low bit rate. dmesg doesn't show anything at all unusual.
I ve been a loyal fan of RedHat Linux for last 5 years.I switched to Ubuntu just few days back.Let me tell you, I ve already started loving it.However I m facing few issues while downloading from the Net.While downloading some softwares from the net using 'Package Manager' or 'BitTorrent Client' or directly through Firefox, I m getting the following error if my computer remains Idle for around 20-30 minutes.Error Says, Check your internet Connectivity'.I then need to Redial to connect to Internet.I never faced this issue in RedHat or Windows.I use to put my machine to download for the entire night and never faced connectivity problem.Where as if the computer is not idle and I m hitting keyboard keys, the download happens smoothly.It seems like some thread is checking my status. and if my status is Idle its disconnecting the net
I have installed Ubuntu 64 10.04 server. I have two nics and have set them up to both be static with their own IP with the correct gateway, network, broadcast, subnet and dns-nameserver. When I have both enabled, I can ping local pc's but I can't ping Internet sites like Google nor can I get out to the Internet with apt-get or Lynx.
If I disable one, then I am able to get out to the Internet. All my configs look good, and it does not matter which one I disable, just so long as there is only one NIC on, everything is good.
Another weird one I think. I have two integrated LAN's on the MB. All was OK in Windows and figured I'd do some work in Fedora 13. When I got there I had no internet. I messed around trying to get it working and gave up; went into Ubuntu; same deal. I booted Windows and the same; no network. I tried the other integrated connection and it worked. No way could I get the other nic to work so I tried shutting right down; pulled the plug; waited a few seconds; plugged it back and booted up and it's working again. Now I'm leery about going into Fedora. Anyone else have this problem. I think it happened to me once bofore and I thought my nic had bit the dust and plugged into the other connection?
Can't use Internet all of a sudden. Same IP address, Gateway, etc... as Windows.
Linux --> Can't use Internet Windows --> Internet OK?!
The Gateway disappears on its own. The IP address and everything else automatically resets to a blank and doesn't save my settings even though I clicked it to save. Restarting the computer doesn't help either.
My network configuration is in a weird situation, that I always need to run dhclient manually each time after a network connection is established. When my computer connects to a router, sometimes it won't get a valid IP, and it uses an automatically generated fake Internet IP. In this situation, it won't connect to the Internet at all. Sometimes it get a valid local network IP, but still cannot connect to WAN, and could only connect to my router's address (both through ping and through router's management webpage). In both situation, it can be solved by a simple dhclient run.
This is my /etc/network/interfaces file:
Code: Select all# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5).
# The loopback network interface auto lo iface lo inet loopback
Does any one have a way to speed up the internet on Fedora 12? I have a dual boot system with Vista x64 on the flip-side, and my wireless connection there is just fine. But when I get on this side, it goes back to the dial-up days (yes I said the DU word). yum updates seem to be just fine, and e-mail seems to be fine. just firefox is slow. And now that I put the x64 Flash in (thanks to leigh123linux), with that working too it seems even a little slower again.
If I plug my iPhone into my laptop via USB cable, the phone gets mounted but no tethering connection is automatically made.I can manually configure ubuntu to tether with my iphone to use it's internet connection like this:
Code: sudo ifconfig wwan0 up sudo dhclient Does anyone know how to make internet connection tethering happen automatically?
I am mounting a remote directory using sshfs, over VPN. If the VPN connection is lost, the directory obviously can't be read. But, when I try to "ls" in its parent directory, the command just stalls. No error messages, and ctrl-d, ctrl-c, ctrl-z don't do anything. The command I ran to mount the directory was: Code: sshfs -o workaround=rename bt@example.com:/dir1 /dir1
I'm sending files to a remote server by way of FTP via a PHP script. With the firewall turned on these files are getting to the remote server with 0kb and the remote server is timing out before all the files are received. When the firewall is turned off the all files are received in tact. There are no outbound rules set in the iptables, looking for ideas on what to check next.
I have a tricky problem which I could soIve with a c program. I wrote one and found I didnt have gcc so I tried to install it. I was told I needed to install packages. I acknowledged and an error was generated gcc-4.4.2-7.fc12.i686 requires libgomp = 4.4.2-7.fc12 I try to install libgomp and go round again.
I am running Ubuntu 10.10, and I would like to use my computer to share the internet connection from an ethernet port. For example, I would like to set up my computer as a wireless access point so I can create a network that other computers can connect to for internet.
I was browsing the available packages to install the weather indicator and noticed that a network indicator was available. apt-get said that it needed to install 'connman' and remove 'network-manager' and 'network-manager-gnome' in order to install the network indicator. I foolishly assumed it knew what it was doing so I went ahead and performed the installation/removal and restarted the computer.
Now I cannot connect to the internet. I only have an ethernet card for connection to the internet, no wireless or otherwise. The configuration I use is not DHCP, but a manual settings of address/subnet/gateway and name servers
When I try to set the network values through the network indicator some of them do not stay set. The gateway value appears to be set, but then after closing down the indicator window completely it comes up with the value 'Modified'. The DNS servers is the only other value that does not stay set, but it only changes to be blank. The connection never works.
So, I downloaded 'network-manager' and 'network-manager-gnome' on another computer, transferred the packages by USB, and reinstalled them (uninstalling connman and the network indicator). But the network connection remains broken. At least with 'network-manager-gnome' the values I set stay set, they just don't work anymore. I've tried editing /etc/network/interfaces to previously working values directly, but they do not seem to have any effect either. The connection no longer works.
I really do not care if I use the network indicator or not at this point, I simply want the network connection to work properly.
Edit: I realize I forgot to say that I'm using Ubuntu 11.04 (upgraded from 10.10). The network card is the "Integrated Broadcom 57780 Gigabit Ethernet controller".
I have recently upgraded to 11.4 and also had to renew an AP (HP ProCurve 10ag). This was several years old but replaced an identical model which had been working well until recently. I thought it would be appropriate to flash newer firmware as the device four releases behind the times. The access point serves partner's XP laptop and my openSUSE 11.4 laptop and after flashing the firmware both machines would make a connection and then break and remake, to the extent that the openSUSE machine became unusable. I thought it was an encryption problem and spent hours changing the AP and Client setups to no avail
After reading a thread here I checked out dmesg and this is what I found:- [78.639247] wlan0: authenticate with 00:1d:b3:4b:ae:14 (try 1) [78.640804] wlan0: authenticated [78.642507] wlan0: associate with 00:1d:b3:4b:ae:14 (try 1) [78.651195] wlan0: RX AssocResp from 00:1d:b3:4b:ae:14 (capab=0x411 status=0 aid=1) [78.651200] wlan0: associated [78.652222] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready [78.652283] cfg80211: Calling CRDA for country: DE [78.674378] cfg80211: Regulatory domain changed to country: DE ..... This went on and on.
I am running Fedora 13 and after my machine is booted my ethernet interface eth0 does not have an IP address. Running
Code:
At the terminal does not work, and I can see that in /var/log/messages I have the following error:
Code:
I assume that the same command was attempted during the boot process (please correct me if I am wrong) to use DHCP to get an address for eth0, but failed for the same reason it is failing after boot when I run it manually, whatever that reason may be.
I noted, however, that eth0 IS in broadcast mode:
Code:
I also noted that running
Code:
Does in fact work and will run DHCP and configure eth0 with an ip address.
It is quite mysterious to me why running 'dhclient eth0' will work, but manually running 'dhclient' does not.
I used ssh to log into my sever that I had and I from there I ran the command dhclient eth by mistake on the server but the serve had an static IP address. Unfortunately I can't ssh back into the server anymore! It replies back with No route not host. Now my questions are. First of all how do I change it back into the previous setting? Secondly, can I do this remotely since the server is in another place and I don't have access to it right now or do I have to go there and sit behind it and play around with it there?
On my PC (fresh FC11 i386 instllataion from CDs), dhclient doesn't work. When it tries to get an IP address with dhclient, it gets No DHCPOFFERS reveived and fails. The ethernet of my PC works fine - I can manually set IP address, netmask, gateway etc. to connect to my persoal Linksys router, but if I change to DHCP, it fails as above. So it's not the problem of the ethernet driver of FC11. I suspect that dhclient of FC11 is buggy. (For the record, DHCP works fine on FC10 and Windows XP with my Linksys router.)

And I see that if I uninstall the dhclient package, I will lose my networkmanager, which I also need, is there a way to have a dhcp server as well as dhclient utility on fedora as it is possible on rhel?
I got a full system crash each time I try to do anything with network. Been fighting with this problem for weeks now. What I did: -tried every driver for broadcom4312 and it turned out that it even crashes with cable net
-got rid of networkmanager ( Mar 11 08:01:43 geburah NetworkManager: <info> Activation (eth1) successful, device activated. Mar 11 08:01:43 geburah NetworkManager: <info> Activation (eth1) Stage 5 of 5 (IP Configure Commit) complete. ) used: ifconfig eth1 up
Commands as root works well when normal user is logged in and connected to net via KDE 4 network manager, but after logoff network is gone. And it is impossible to get it back because command mentioned above stops working!
I have just installled fedora, and I am puzzled by dhclient-script. Because it gives the router ip as nameserver 192.168.0.1. I have had other linux distro on same machine that resolves the correct nameserver without any configuring.
Does anyone know how to get your ISP:s nameservers instead in /etc/resolv.conf when running dhclient from CLI? I have thought about edit /sbin/dhclient-script. But if that is the case. Which option should I edit?

Using Fedora 12 where are your repo sites? so i can download packages from friends computer till i can get connected. also the ones for the codecs (play DVD'S, mp3's, etc)
After a fresh installation my internet connection was working. but after yum update I am not able to connect to the internet. it is showing no internet connection.
I just got F14 installed on my pendrive with persistent data and I want to be able to play DVD's, .mp3, .avi etc. So of course I try to download vlc, but I have no internet connection on F14 and can't find any simple, non-RPMfusion way to download the binaries (I had an awful experience with the source a while ago). Does anyone know where I can get them?
