Ubuntu Networking :: Fails To Complete DHCP Transaction?
Feb 7, 2010
I know there are hundreds of similar questions about suspend on Ubuntu, but none of the fixes they use work for me. This bug is the only thing that stops me from using Ubuntu - I put computer to sleep (suspend to ram) and after resume I have no network. The only way to get network back is to restart.
Looking at the logs, it seems that NetworkManager starts, finds the device and then fails to complete DHCP transaction. I don't know what causes the problem, probably this line: "via-rhine: Reset not complete yet. Trying harder." Does anyone know possible reason for this? Here is the log:

I am running Fedora 8. Each time I run a YUM command, I get the message that there are unfinished transactions, and to run yum-complete-transaction. Upon running yum-complete-transaction, it fails with this error. How can I remove this uncompleted transaction so I can finish the last one?
Running Admin>Software Updates generated this error: There are unfinished transactions remaining. Please run yum-complete-transaction as root. That's what I tried to do.

Whenever I use yum after a recent update I get the message that I should run yum-complete-transaction.I have yum-utils installed but I keep getting the message that the command is not found.post the command I should be using to run it so I can see it it's just me typing the wrong thing into the shell?
whenever i'm trying to install package it shows one warning 'yum-complete-transaction'. but i try to yum-complete-transaction command but i got the result bash: yum-complete-transaction: command not found. so how to clear this warning, y this warning comes
I have OpenVPN set up on my server at home to allow me into my home network when I'm away from home. When I set it up, I tested it using my friend's wifi so I know it works on a local geographic scale.Now I'm away from home, the TLS handshake fails to complete within 60 seconds. I assume it's timing out, as I can tracepath to the server on port 1194 successfully.From reading the OpenVPN documentation, I thought that adding "tls-timeout=120" to the client's config file would double the time allowed,but the handshake still fails with the same error message:
Code: Tue Oct 19 10:45:17 2010 us=930956 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity) Tue Oct 19 10:45:17 2010 us=931012 TLS Error: TLS handshake failed
Why is the option not being read correctly from the file - does it need to be in the server's config file also?
Ubuntu Jaunty Server connected via eth0 to a Billion residential ADSL router. I've locked the server MAC address to a specific IP in the router and set the DHCP renewal times to the longest possible times. For a certain number of days, the server will remain connected to the router, but then for some reason (the last time it was after about a month), the server loses it's connect and dumps into syslog the following:
Code: Jun 2 17:10:15 defiant dhclient: DHCPREQUEST of 192.168.1.105 on eth0 to 192.168.1.254 port 67 Jun 2 17:11:26 defiant dhclient: last message repeated 5 times
This one has been bugging me for some time now. The network interface (as defined in Debian's /etc/network/interfaces file) fails to obtain an IP address from myuter. However dhclient br0 does.I'm using br0 since I run a XP virtual machine.network/interface changes are from a Debian howto on setting up the tap interface.As near as I can tell, the /etc/init.d/networking script basically calls /sbin/ifup -a. ifup is a binary.My /etc/network/interfaces file is:
installing package kernel-debug-2.6.31.6-166.fc12.i686 needs 27MB on the /boot filesystem installing package kernel-doc-2.6.31.6-166.fc12.noarch needs 27MB on the /boot filesystem installing package setroubleshoot-2.2.50-1.fc12.i686 needs 27MB on the /boot filesystem installing package perf-2.6.31.6-166.fc12.noarch needs 27MB on the /boot filesystem installing package hunspell-1.2.8-13.fc12.i686 needs 27MB on the /boot filesystem installing package gettext-0.17-16.fc12.i686 needs 27MB on the /boot filesystem"
I have boot as a separate partition, this time around I have set it to ext4 for the first time. That partition is only 250 Mb, but that has always been sufficient in the past, perhaps I am holding too many kernels or kernel versions?
so i have installed compiz 9 and it didn't quite work for me, then i have reverted to compiz 8 and things where fine, but after a while my desktop started slowing down for no apparent reason, so i decided to install the nVIDIA drivers from the manufacturer's site, good, i typed in:
Code: sudo /etc/init.d/gdm stop and then i installed the drivers with the sh command, stuff went right, but i could not

Back in April I set up a Ubuntu DHCP server and a multiple VLAN network [URL] to migrate our various servers, workstations, etc off the 192.168.1.1 /24 network that everything was on because we where running out of address space. I built out the new network and everything worked great except our AD server would never get an IP address from the DHCP server (static reservation) and even if I set the IP statically on the AD server it couldn't ping the gateway and noone could log in. After several attempts to resolve this, including bringing in outside help, we where never able to figure out what the problem was.
Now 6 months later I have time to revisit the issue without effecting the live network. I used Acronis and imaged the AD server last Friday, cloned it on to another box with the same hardware, and put it up on the new network that's been sitting unused for the last 6 months. Today when I statically set the IP on the AD server (which is what I want) it connects and I can ping it's gateway 192.168.1.1 and all the way across vlans to a test sales agent workstation at 192.168.8.xxx on vlan 800 but only if I statically assign the agents station an IP address. When I try to get an IP address via DHCP it fails as destination unreachable. Nothing has changed in the last 6 months on the DHCP server but now it for some reason can't ping its default gateway 192.168.1.1. All of the config files are the same as they where left from the post linked above aside from the vlan id's used where changed from 1's to 100's (i.e. vlan 3 is now vlan 300) /etc/network/interfaces
Code:
auto lo iface lo inet loopback auto vlan100 iface vlan100 inet static
[code]....
why it can't reach the gateway, when I do a tcpdump I can see the DHCP requests come in on eth0 but the server never responds and I'm pretty sure its because it isn't "seeing" them since it thinks there isn't a network connection but I don't know how to trouble shoot to find out where the problem lies.

Currently I have my eth0 interface getting a DHCP address but at times the DHCP server will not be reachable. Sooo what I would like my server to do is if it cannot find a DHCP server assign a static address to eth0. Then start the DHCP service so it can then dish out some addresses.How can I do this? Surely it is possible
I am puzzled with trying to configure a linux (openSUSE) client to dhcp to eBox DHCP server. I am using dhclient to lease an IP address with dhclient eth0 -s 10.45.48.108 and get a response
openSUSE11232CL1 dhclient: DHCPDISCOVER on eth0 to 10.45.48.108 port 67 interval 4 openSUSE11232CL1 dhclient: DHCPOFFER from 10.45.48.108 openSUSE11232CL1 dhclient: DHCPREQUEST on eth0 to 10.45.48.108 port 67 openSUSE11232CL1 dhclient: send_packet: Network is unreachable openSUSE11232CL1 dhclient: send_packet: please consult README file regarding broadcast address.
The server reports eBox141 dhcpd: DHCPDISCOVER from 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0 eBox141 dhcpd: DHCPOFFER on 10.45.200.2 to 00:0c:29:3e:57:a3 (openSUSE11232CL1.domain.net) via eth0
I interpret this as the server receives the request and the client accepting it but the lease does not last long and the connection breaks. what this could be and why the connection breaks? Or my undestanding is totally wrong on how it works and should work? And BTW, where is that README file that's referenced in the message I receive on the client?
I was trying to update my Fedora 15 amd64 when a Error Notification popped up saying "An unspecified TRANSACTION ERROR has occured". More details: "could not add package update for fedora-release-rawhide-15-3(noarch)updates: fedora-release-rawhide-15-3.noarch".
I've run into a situation where when performing a pxe/preseed install the system boots up into the install without issue, getting a dhcp address, then the installer begins to configure the network and it gets to where it request a dhcp address and it instantly fails the install stating that we are either not using dhcp or it's slow.
I've added d-i netcfg/dhcp_timeout string 600 to the preseed file but it doesn't seem to be honoured here since it doesn't wait 600 seconds before failing. I have 2 other identical systems that install using the same preseed file but the installer completes as expected. This system has no issues installing centos just debian fails. I did try, once the install failed, to switch to the console and run udhcpc and the server received the address reserved for it.
Is there a method to force debian installer to wait a bit longer for the dhcp server besides what I've already done?
I'm having some problems bringing up my wireless card at boot time on my Red Hat Linux 9.0 box. After some investigation with the boot scripts, I noticed that it was having problems with the DHCP negotiations when the ifup wlan0 command is issued.I then tested the command outside of the booting process and everytime the command is issued the first time, the dhclient fails to get any DHCP offers and returns with the message Unable to obtain a lease on first try. Exiting. and then exits.
If I then issue the same ifup command again a second time, it successfully receives a DHCP offer from the router and receives the needed IP address, and after this, the Internet connection on the box works fine. It is consistently doing this everytime. Why is it failing to obtain a lease the first time?
I installed fedora 12 today...installation went fine. Tried to run the software update ( which includes 415 fixes) and got the following
Transaction error:- an unspecified transaction error has occurred. More information is available in the following report.
More details show:- could not add package update for abrt-plugin-runpp-1.0.4-1fc12(i686)updates:abrt-plugin-runapp-1.0.4-1.fc12.i686
I have unchecked the box in the update list to be installed, but the software update insists that this update is needed. I cannot progress any further than this error message..
I am struggling with what might be a minor problem. I have a home computer which I would like to setup as a webserver and hence give it a static IP address. It is connected to by wire to a router that is connected to the WAN via PPPOE. If I enable the network card on DHCP it works fine in browsing the web. If I now set it to static IP address it does not brown. Essentially I use the command setup to run the static IP setup. I then set my IP address to 192.168.254.X , the subnet mask 255.255.255.0 and the default gateway to 192.168.254.1 (this is the router connected to the WAN). I am able to ping the router, however when I try and browse on static it does not work. Your help will be most appreciated as this has taken way too long to solve and I have Googled as much without success.
I have downloaded the Wheezy DVD 1 and started the istallation process. The installation time is strangely very short in respect to the Squeeze release, anyway
The GRUB installation step fails. I terminated the installation without a bootloader and rebooted from DVD with the rescue boot option.
Now I asked for a console to try to manually install the bootloader but the following command:
# grub-install /dev/sda1 [where sda1 is my root partition]
I currently have some windows (Win7 Ultimate 64-bit) shares automounted to my linux laptop whenever I am on my home wireless network. I have this functionality set up using autofs/CIFS and it works well, except for one issue: The directory listings for the mounted windows shares are incomplete, i.e. when listing the directories on the linux machine, it only lists a fraction of what is available in the actual share. One directory returns 28 of 51 files present, for example, and another 33 of 60. NOTE: None of the files on the windows shares are 'hidden' or in any way shared differently than the others.
Here is my problem: I am using ubuntu 10.10 64 bit installed on a HP tx2 1274nr laptop. I can get my wireless to work on both the Broadcom B43 wireless driver and the Broadcom STA wireless driver. Though only one can be active at a time.
My problem lies in I can activate either driver until I reboot the laptop. then it becomes inactive.
Is there a fix for this problem. I would like to have my wireless active after restarting.
I have an embedded device for which I've created an html configuration page. This page allows you to set static IPs, dhcp, and can scan for wireless devices.My problem is that in order to access the device it requires that it runs as a dhcp server otherwise people are not assigned an IP and so can not access the embedded devices static IP. (This config page is for the laymen and so they are not the type who are able to set up their own static IPs). One of the potential options is to have the device connect to the network on eth0 acting as a dhcp client. However this prevents me from running a dhcp server.One solution I can think of is running a dhcp server only if it doesn't detect another dhcp server running on the network.

I'm trying to install a Netgear WG311T V1H1, rev A3, Atheros AR2414 mac 0x79m phy0x45 on Centos 2.6.18-128.el5. Two methods are offered. The distribution comes with Madwifi's latest driver, ath5K, but it is not supported for this card and is unstable. It will connect but has variable data rates and will drop out with long downloads. My research indicates that the madwifi 0.9.4 driver should support this card. Both methods call for blacklisting ath5k, which I did.
1. Following Centos directions, [URL], I installed the configured RPM Forge and did yum install madwifi, which was successful. The command modprobe ath_pci produces the error "module ath_pci not found." It appears that the RPMForge download did not install these needed bits. So my fundamental question is where is the ath_pci? It is not on the machine.
2. Following the Madwifi directions, I did yum install gcc make perl, which was successful. Their next step, the 'make' command, yielded the KERNELPATH error described on their page [URL]. It points to /lib/modules/2.6.18-128.el5/build, but 'build' is a path, not a file or directory. Installing kernel-devel to get the build files on the system was suggested by another web page, and I did it with yum install kernel-devel, and it was successful, but did not change the error. The literature says I can redirect the make command to the correct spot, but there does not seem to be a correct spot.
