  • Why Wifi no longer works 12.04.1

    - by Roger
    starting this morning over wifi (Realtek RTL8188CE) on CLEVO W253HU. May be due to the update before yesterday, more pilot managed, but somehow it worked yesterday. If someone has an idea of the problem.

    - by lorrenuy
    I have a problem with the hardware broadcom wifi. I press the hotkey fn+f2 to activate the hardware and this will not work. I'll look at the drivers but it appears to be installed. How can I solve this problem? Ubuntu is all new to me so if possible, give me a clear explanation. Now do I connect the lan cable. I use the Ubuntu 11.10 lawrence@lawrence-Vostro-1000:~$ sudo lshw -class network [sudo] password for lawrence: PCI (sysfs) *-network description: Network controller product: BCM4311 802.11b/g WLAN vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:05:00.0 version: 01 width: 32 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: driver=b43-pci-bridge latency=0 resources: irq:18 memory:c0200000-c0203fff *-network description: Ethernet interface product: BCM4401-B0 100Base-TX vendor: Broadcom Corporation physical id: 0 bus info: pci@0000:08:00.0 logical name: eth1 version: 02 serial: 00:1c:23:a2:b9:a9 size: 100Mbit/s capacity: 100Mbit/s width: 32 bits clock: 33MHz capabilities: pm bus_master cap_list ethernet physical mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=b44 driverversion=2.0 duplex=full ip=192.168.1.18 latency=64 link=yes multicast=yes port=twisted pair speed=100Mbit/s resources: irq:21 memory:c0300000-c0301fff lawrence@lawrence-Vostro-1000:~$ lawrence@lawrence-Vostro-1000:~$ rfkill list all 0: dell-wifi: Wireless LAN Soft blocked: yes Hard blocked: yes

  • permanently load module

    - by Radu
    I have a Compaq Presario CQ-61 320SQ, I am using Ubuntu 10.04 because after update to 10.10 my mouse and touchpad won't work, network won't work, sound won't work ... (I managed to fix most of them after almost a month of googling, but not all, my 2 Desktops have no problem with 10.10) so I decided to switch back to 10.04, where I have a problem: My broadband speed is very low beacause of the kernel module r8169, I downloaded the good module r8101 and every time the computer boots have a rc.local entry to fix this. Question: Can I load the modul permanently from a specific location. I heard about /etc/modules but there I need the module name, but I have to load it from a specific path (where is the default path for that) Thank you. So I studied the script: It creates the file r8101.ko in /lib/modules/uname -r/kernel/drivers/net so I think as long as nobody will delete that file, and I don't update the kernel, maybe adding r8108 to /etc/modules will work, and add r8169 to blacklist ... I will give it a try. EDIT2: So I added r8101 to /etc/modules and blacklist r8169 to /etc/modprobe.d/blacklist.conf It still uses the old module, lsmod prints: radu@adu:~$ lsmod | grep r8 r8101 67626 0 r8169 34108 0 mii 4381 1 r8169 EDIT: the module is loaded using this script that came with it: #!/bin/sh # invoke insmod with all arguments we got # and use a pathname, as insmod doesn't look in . by default TARGET_PATH=/lib/modules/`uname -r`/kernel/drivers/net echo echo "Check old driver and unload it." check=`lsmod | grep r8169` if [ "$check" != "" ]; then echo "rmmod r8169" /sbin/rmmod r8169 fi check=`lsmod | grep r8101` if [ "$check" != "" ]; then echo "rmmod r8101" /sbin/rmmod r8101 fi echo "Build the module and install" echo "-------------------------------" >> log.txt date 1>>log.txt make all 1>>log.txt || exit 1 module=`ls src/*.ko` module=${module#src/} module=${module%.ko} if [ "$module" == "" ]; then echo "No driver exists!!!" exit 1 elif [ "$module" != "r8169" ]; then if test -e $TARGET_PATH/r8169.ko ; then echo "Backup r8169.ko" if test -e $TARGET_PATH/r8169.bak ; then i=0 while test -e $TARGET_PATH/r8169.bak$i do i=$(($i+1)) done echo "rename r8169.ko to r8169.bak$i" mv $TARGET_PATH/r8169.ko $TARGET_PATH/r8169.bak$i else echo "rename r8169.ko to r8169.bak" mv $TARGET_PATH/r8169.ko $TARGET_PATH/r8169.bak fi fi fi echo "Depending module.

  • Problem with switch dell 6224

    - by Matias
    Hello, we just have upgraded the firmware of a dell 6224 power connect switch and it won't reload. These are the symptons: - I power up the switch having the serial cable connected to it and the switch outputs nothing. The configuration of the serial console is fine: 9600 bds, etc... In fact, before the upgrade, I was connected to the switch through the very same cable. - Reseting the switch with its reset pinhole does not reset the switch: the power and fan lights powers off while I keep pressed the pinhole, but the switch itself does not resets. - When I connect an UTP cable to one of the switches port, the green lights don't flash, but ''mii-tool eth0'' in my laptop shows there is link!! The only thing I see in the output, different from other upgrades I've done, is this line at the end: Erasing Boot Flash.....^^^^Done. Any help or idea will be more than welcome!! Thanks!! console#show version Image Descriptions image1 : image2 : Images currently available on Flash -------------------------------------------------------------------- unit image1 image2 current-active next-active 1 <none> 3.0.0.8 image2 image2 console#boot system image2 Activating image image2 .. console#update bootcode Update bootcode and reset (Y/N)?

  • The RTL8111/8168B NIC under Linux and the r8168 driver

    - by nik
    So I've got one of the infamous R8168 Realtek ethernet NIC, which have some problems under Linux. After some research, I found out I had to use the r8168 driver for this card (and not the r8169 which still loads when nothing else is available), which I did. So now everything works fine... Sort of. My download and upload rates are more than halved compared to what I should get. When I test (with eg. speedtest) I get something like 20M (often 15M) in download and 30M in upload, but if I test under Windows (everything is otherwise identical: same ethernet cable, same connection, at the same time of the day (well 5 min apart)...), I get 50M upload/download (which is what I expect). Where can it come from? Here's some info: ~ # lspci [...] 06:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

  • NIC are not advertising Correct Speeds

    - by Squidly
    I have an IBM x336 that is not advertising the proper LINK speeds. One interface is the other is not. I've tried to Force it to 1000/Full but then it just shows link down. I have confirmed the switch is set to auto negotiate like my switches. I have also changed out my Ethernet Cables. I'm at a loss where to look further. I have verified that it will connect at 1G on a different swtich. This also has happened on two different servers on the same switch. This is my output from mii-tool -v for each interface. eth0: negotiated 100baseTx-FD, link ok product info: vendor 00:08:18, model 24 rev 0 basic mode: autonegotiation enabled basic status: autonegotiation complete, link ok capabilities: 1000baseT-HD 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD advertising: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control link partner: 1000baseT-HD 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD eth1: negotiated 1000baseT-FD flow-control, link ok product info: vendor 00:08:18, model 24 rev 0 basic mode: autonegotiation enabled basic status: autonegotiation complete, link ok capabilities: 1000baseT-HD 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD advertising: 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD flow-control link partner: 1000baseT-HD 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD

  • Connecting to same public IP from different locations yields different results

    - by DHall
    Since yesterday I've been unable to access one of my favorite time-wasting sites, boston.com. It starts to load but then it gets redirected to pagesinxt or something like that. After some investigation, I've narrowed it down to an issue with cache.boston.com, but only from my work location. I found the IP (216.38.160.107) , but even that doesn't work correctly from here at work. When I do a telnet 216.38.160.107 80 GET http://cache.boston.com/universal/css/hp_bgcom.css from another location, I get a nice long CSS, as expected. From here, I get an error (trimmed for size): HTTP/1.1 400 Bad Request Your request could not be processed. Request could not be handled This could be caused by a misconfiguration, or possibly a malformed request. For assistance, contact your network support team. Is there any way I can troubleshoot this further on my end? Tracert doesn't tell me anything too useful: Tracing route to vwrpx1.ttn.xpc-mii.net [216.38.160.107] over a maximum of 30 hops: 1 * * * Request timed out. Since it's not really work-related, I don't really want to bring it up to our network team unless I know what's going on, or if there's some risk to the network (ex. malware or something)

  • PC hangs and reboots from time to time

    - by Bevor
    Hello, I have a very strange problem: Since I have my new PC, I have always had problems with it. From time to time the computer freezes for some seconds and suddendly reboots by itself. I've had this problem since Ubuntu 9.10. The same with 10.04 and 10.10. That's why I don't think it's a software failure because the problem persist too long. It doesn't have anything to do with what I'm doing at this time. Sometimes I listen to music, sometimes I only use Firefox, sometimes I'm running 2 or 3 VMs, sometimes I watch DVD. So it's not isolatable. I could freeze once a day or once a week. I put the PC to the vendor twice(!). The first time they changed my power supply but the problem persisted. The second time they told me that they made some heavy performance tests 50 hours long but they didn't find anything. (How can that be that I have daily freezes with normal usage). The vendor didn't check the hard discs because they used their own disc with Windows. (So they never checked the Linux installation). Yesterday I made some intensive hard disc scans with "SMART" but no errors were found. I ran memtest for 3 times but no errors found. I already had this problem in my old flat, so I doubt that I has something to do with current fluctuation. I already tried another electrical socket and changed to connector strip but the problem persists. At the moment I removed 2 of the RAMs (2x 2GB). In all I have 6GB, 2x2GB and 2x1GB. Could this difference maybe be a problem? Here is a list of my components. I hope that anybody find something I didn't think about yet.

  • Kernel oops on Linux running in VirtualBox breaks some IO-related functionality on the server

    - by Kristoffer E
    We are having problems with CentOS release 6.3 running in VirtualBox on Windows 7 machines. The symptoms are the following: Everything works as normal for several hours, even days. Then something happens which breaks the system. What we still can do after this something happens: Access the web server Use existing SSH sessions to run top and free What does not work: Starting new SSH sessions (hangs after username and password is entered) Running ls in existing SSH sessions (hangs) SSI includes from our web servers that fetch data from remote machines probably more What we see on the server when this something happens is the following: Load average go from basically nothing to around 3 CPU usage is still low (5%) Disk activity is low (running iostat) Plenty of memory available Plenty of disk space available In /var/log/messages we get the following: Jun 14 01:10:48 devvm kernel: e1000 0000:00:03.0: eth0: Detected Tx Unit Hang Jun 14 01:10:48 devvm kernel: Tx Queue <0> Jun 14 01:10:48 devvm kernel: TDH <2e> Jun 14 01:10:48 devvm kernel: TDT <30> Jun 14 01:10:48 devvm kernel: next_to_use <30> Jun 14 01:10:48 devvm kernel: next_to_clean <2e> Jun 14 01:10:48 devvm kernel: buffer_info[next_to_clean] Jun 14 01:10:48 devvm kernel: time_stamp <1038284db> Jun 14 01:10:48 devvm kernel: next_to_watch <2f> Jun 14 01:10:48 devvm kernel: jiffies <103828b42> Jun 14 01:10:48 devvm kernel: next_to_watch.status <0> Jun 14 01:10:50 devvm kernel: e1000 0000:00:03.0: eth0: Detected Tx Unit Hang Jun 14 01:10:50 devvm kernel: Tx Queue <0> Jun 14 01:10:50 devvm kernel: TDH <2e> Jun 14 01:10:50 devvm kernel: TDT <30> Jun 14 01:10:50 devvm kernel: next_to_use <30> Jun 14 01:10:50 devvm kernel: next_to_clean <2e> Jun 14 01:10:50 devvm kernel: buffer_info[next_to_clean] Jun 14 01:10:50 devvm kernel: time_stamp <1038284db> Jun 14 01:10:50 devvm kernel: next_to_watch <2f> Jun 14 01:10:50 devvm kernel: jiffies <103829312> Jun 14 01:10:50 devvm kernel: next_to_watch.status <0> Jun 14 01:10:52 devvm kernel: ------------[ cut here ]------------ Jun 14 01:10:52 devvm kernel: WARNING: at net/sched/sch_generic.c:261 dev_watchdog+0x26d/0x280() (Not tainted) Jun 14 01:10:52 devvm kernel: Hardware name: VirtualBox Jun 14 01:10:52 devvm kernel: NETDEV WATCHDOG: eth0 (e1000): transmit queue 0 timed out Jun 14 01:10:52 devvm kernel: Modules linked in: vboxsf(U) ipv6 ppdev parport_pc parport microcode sg vboxguest(U) i2c_piix4 i2c_core e1000 snd_intel8x0 snd_ac97_codec ac97_bus snd_seq snd_seq_device snd_pcm snd_timer snd soundcore snd_page_alloc pcnet32 mii ext4 mbcache jbd2 sd_mod crc_t10dif ahci dm_mirror dm_region_hash dm_log dm_mod [last unloaded: scsi_wait_scan] Jun 14 01:10:52 devvm kernel: Pid: 0, comm: swapper Not tainted 2.6.32-279.el6.x86_64 #1 Jun 14 01:10:52 devvm kernel: Call Trace: Jun 14 01:10:52 devvm kernel: <IRQ> [<ffffffff8106b747>] ? warn_slowpath_common+0x87/0xc0 Jun 14 01:10:52 devvm kernel: [<ffffffff8106b836>] ? warn_slowpath_fmt+0x46/0x50 Jun 14 01:10:52 devvm kernel: [<ffffffff814595fd>] ? dev_watchdog+0x26d/0x280 Jun 14 01:10:52 devvm kernel: [<ffffffff81099138>] ? sched_clock_cpu+0xb8/0x110 Jun 14 01:10:52 devvm kernel: [<ffffffff81459390>] ? dev_watchdog+0x0/0x280 Jun 14 01:10:52 devvm kernel: [<ffffffff8107e897>] ? run_timer_softirq+0x197/0x340 Jun 14 01:10:52 devvm kernel: [<ffffffff810a21c0>] ? tick_sched_timer+0x0/0xc0 Jun 14 01:10:52 devvm kernel: [<ffffffff8102b40d>] ? lapic_next_event+0x1d/0x30 Jun 14 01:10:52 devvm kernel: [<ffffffff81073ec1>] ? __do_softirq+0xc1/0x1e0 Jun 14 01:10:52 devvm kernel: [<ffffffff81096c50>] ? hrtimer_interrupt+0x140/0x250 Jun 14 01:10:52 devvm kernel: [<ffffffff8100c24c>] ? call_softirq+0x1c/0x30 Jun 14 01:10:52 devvm kernel: [<ffffffff8100de85>] ? do_softirq+0x65/0xa0 Jun 14 01:10:52 devvm kernel: [<ffffffff81073ca5>] ? irq_exit+0x85/0x90 Jun 14 01:10:52 devvm kernel: [<ffffffff81505be0>] ? smp_apic_timer_interrupt+0x70/0x9b Jun 14 01:10:52 devvm kernel: [<ffffffff8100bc13>] ? apic_timer_interrupt+0x13/0x20 Jun 14 01:10:52 devvm kernel: <EOI> [<ffffffff810387cb>] ? native_safe_halt+0xb/0x10 Jun 14 01:10:52 devvm kernel: [<ffffffff810149cd>] ? default_idle+0x4d/0xb0 Jun 14 01:10:52 devvm kernel: [<ffffffff81009e06>] ? cpu_idle+0xb6/0x110 Jun 14 01:10:52 devvm kernel: [<ffffffff814e433a>] ? rest_init+0x7a/0x80 Jun 14 01:10:52 devvm kernel: [<ffffffff81c21f7b>] ? start_kernel+0x424/0x430 Jun 14 01:10:52 devvm kernel: [<ffffffff81c2133a>] ? x86_64_start_reservations+0x125/0x129 Jun 14 01:10:52 devvm kernel: [<ffffffff81c21438>] ? x86_64_start_kernel+0xfa/0x109 Jun 14 01:10:52 devvm kernel: ---[ end trace 2c7bb984812cf120 ]--- Jun 14 01:10:52 devvm kernel: e1000 0000:00:03.0: eth0: Reset adapter Jun 14 01:10:53 devvm abrtd: Directory 'oops-2013-06-14-01:10:53-1537-0' creation detected Jun 14 01:10:53 devvm abrt-dump-oops: Reported 1 kernel oopses to Abrt Jun 14 01:10:53 devvm abrtd: Can't open file '/var/spool/abrt/oops-2013-06-14-01:10:53-1537-0/uid': No such file or directory Jun 14 01:10:55 devvm kernel: Bridge firewalling registered After this we see for a while, every two minutes: Jun 14 01:14:22 devvm kernel: INFO: task events/0:19 blocked for more than 120 seconds.

  • What is an elegant way to solve this max and min problem in Ruby or Python?

    - by ????
    The following can be done by step by step, somewhat clumsy way, but I wonder if there are elegant method to do it. There is a page: http://www.mariowiki.com/Mario_Kart_Wii, where there are 2 tables... there is Mario - 6 2 2 3 - - Luigi 2 6 - - - - - Diddy Kong - - 3 - 3 - 5 [...] The name "Mario", etc are the Mario Kart Wii character names. The numbers are for bonus points for: Speed Weight Acceleration Handling Drift Off-Road Mini-Turbo and then there is table 2 Standard Bike S 39 21 51 51 54 43 48 Out Bullet Bike 53 24 32 35 67 29 67 In Bubble Bike / Jet Bubble 48 27 40 40 45 35 37 In [...] These are also the characteristics for the Bike or Kart. I wonder what's the most elegant solution for finding all the maximum combinations of Speed, Weight, Acceleration, etc, and also for the minimum, either by directly using the HTML on that page or copy and pasting the numbers into a text file. Actually, in that character table, Mario to Bower Jr are all medium characters, Baby Mario to Dry Bones are small characters, and the rest are all big characters, except the small, medium, or large Mii are just as what the name says. Small characters can only ride small bike or small kart, and so forth for medium and large.

  • Linux bonded Interfaces hanging periodically

    - by David
    I've several hosts that are showing problems with connectivity. When working from the command line, for example, typing is frozen for a second or so, then recovers - then it does it again. The most egregious example host would freeze (input) for 15-30 seconds, then recover and go out 5 seconds later. Switching cables didn't do anything - but removing one of the physical cables caused everything to clear up instantly (which why I think this is a network problem). Looking at the network I couldn't see any packets floating that would explain this. These ethernet interfaces (Gigabit Dell) were working normally previously, but since we moved the systems - and put them on a new set of switches - this has been a problem on multiple theoretically identically-configured hosts. The original switches were an HP Procurve 1810-24G and an HP Procurve 1800-24G connected with LLDP; the new switches are both Cisco SG 200-26, which I understand are rebranded Linksys switches. Is this caused by a problem with the switches? Is it the switch configurations? Are the Cisco switches incapable of handling this? I don't see where the configuration is located; I searched the usual /etc/sysconfig/network/devices but there's nothing in there about options (like mii polling) and nothing about the method of balancing the two. Searching scripts, I can't find anything in /etc/init.d/network either. The hosts are almost all Red Hat Enterprise Linux 5.x systems (5.6, 5.7) but some are Ubuntu Server 10.04.3 Lucid Lynx. I need help with both if it comes to that. UPDATE: We're also seeing some problems with servers on the original switches. The HP switches and the Cisco switches are also interconnected (temporarily); there is a cable run from one switch to the next. Pings on any of these hosts show about one ICMP packet out of every 5-6 getting dropped (timed out). Could there be an interaction between the two switches? Oh, and the hosts are using bonding with Balance-RR as the method.

  • Cannot ping host stale ARP cache?

    - by gkchicago
    I am having a strange issue with a Debian (Lenny/Linux 2.6.26-2-amd64) that has been driving me nuts. On some machines within my network I can ping the host in question just fine, other times I have to manually hard-code the ARP ethernet address for the IP in order to establish connectivity. I've finally worked it down to somehow involving ARP. I just found how to fix it in a way that made it work but I'm looking for help explaining this issue and also I don't trust my fix to be permanent.. My thought process has been the following but I just can't make any sense out of it: Could it be the card? (Intel 82555 rev 4) Could it be because there are two network cards? (Default route is eth0) Could it be because of the network aliases? Lenny? AMD x86_64? Argh..

  • Is it possible to repair a Cisco 3500 XL (3548) switch with POST Error messages?

    - by Alex
    I've got an old Cisco 3500 XL, and it seems to have hardware issues. I've loaded the latest IOS and cleared all config. Does anyone have any experience fixing the switch core? I'm a reasonably competent SMD solderer, can I replace/reflow some chips? I've checked the power supply voltages and it's all within tolerance, and no visible signs of any component damage. Some chips are hot to the touch. I understand that these were EOL as of 2007, but should have a lifetime warranty for the electronics. I don't have a Cisco support contract, so I can't file a ticket. What should I do?

  • VirtualBox - Public Static IP for a Debian Guest on a Dedicated Server

    - by user86296
    Goal: I want to run a Debian-squeeze-Guest in VirtualBox and it's own public static ip. I found tons of threads about this topic, but all in all I'm now trying for 10 hours (reading the manual, the forums, trying to learn about networking concepts & commands) to give a Guest his own public static ip (so that the Guest is similar to a vServer you can order from a hosting company), but wasn't able to. Since I'm a big noob as far as networking stuff is concerned, I'm probably doing something wrong.(please bear with me :-) ) Situation: VirtualBox 4.0.10 (headless no gui) is running on a dedicated Debian-Server, the Guest OS is Debian as well. The server has a static ip and I ordered an additional ip for a VM. Problem description: Upto now I was able to use NAT to access the VM from the outside and to setup an internal network between several Guests and all of this worked very well. When setting NIC 1 to bridged and configuring a public static ip on the guest, the guest was unpingable. (neither from outside, nor from the host) I could connect to the guest via the internal network, from another vm, though. ( VBoxManage controlvm VMGuest nic1 bridged eth0 ) ( configuration attempt of static-ip on the guest '/etc/network/interfaces' is below) Please let me know what I'm doing wrong, or what I can try to get it to work, or if you need more info. I think I've read that with a current VirtualBox-version for bridged networking no special host-configuration is necessary, is that accurate, or might that be the problem? Additional Info Info I got from the hosting company about the additional IP Please note that you can use the IP address only for this server.

  • KVM/Libvirt bridged/routed networking not working on newer guest kernels

    - by SharkWipf
    I have a dedicated server running Debian 6, with Libvirt (0.9.11.3) and Qemu-KVM (qemu-kvm-1.0+dfsg-11, Debian). I am having a problem getting bridged/routed networking to work in KVM guests with newer kernels (2.6.38). NATted networking works fine though. Older kernels work perfectly fine as well. The host kernel is at version 3.2.0-2-amd64, the problem was also there on an older host kernel. The contents of the host's /etc/network/interfaces (ip removed): # Loopback device: auto lo iface lo inet loopback # bridge auto br0 iface br0 inet static address 176.9.xx.xx broadcast 176.9.xx.xx netmask 255.255.255.224 gateway 176.9.xx.xx pointopoint 176.9.xx.xx bridge_ports eth0 bridge_stp off bridge_maxwait 0 bridge_fd 0 up route add -host 176.9.xx.xx dev br0 # VM IP post-up mii-tool -F 100baseTx-FD br0 # default route to access subnet up route add -net 176.9.xx.xx netmask 255.255.255.224 gw 176.9.xx.xx br0 The output of ifconfig -a on the host: br0 Link encap:Ethernet HWaddr 54:04:a6:8a:66:13 inet addr:176.9.xx.xx Bcast:176.9.xx.xx Mask:255.255.255.224 inet6 addr: fe80::5604:a6ff:fe8a:6613/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:20216729 errors:0 dropped:0 overruns:0 frame:0 TX packets:19962220 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:14144528601 (13.1 GiB) TX bytes:7990702656 (7.4 GiB) eth0 Link encap:Ethernet HWaddr 54:04:a6:8a:66:13 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:26991788 errors:0 dropped:12066 overruns:0 frame:0 TX packets:19737261 errors:270082 dropped:0 overruns:0 carrier:270082 collisions:1686317 txqueuelen:1000 RX bytes:15459970915 (14.3 GiB) TX bytes:6661808415 (6.2 GiB) Interrupt:17 Memory:fe500000-fe520000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:6240133 errors:0 dropped:0 overruns:0 frame:0 TX packets:6240133 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:6081956230 (5.6 GiB) TX bytes:6081956230 (5.6 GiB) virbr0 Link encap:Ethernet HWaddr 52:54:00:79:e4:5a inet addr:192.168.100.1 Bcast:192.168.100.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:225016 errors:0 dropped:0 overruns:0 frame:0 TX packets:412958 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:16284276 (15.5 MiB) TX bytes:687827984 (655.9 MiB) virbr0-nic Link encap:Ethernet HWaddr 52:54:00:79:e4:5a BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) vnet0 Link encap:Ethernet HWaddr fe:54:00:93:4e:68 inet6 addr: fe80::fc54:ff:fe93:4e68/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:607670 errors:0 dropped:0 overruns:0 frame:0 TX packets:5932089 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:83574773 (79.7 MiB) TX bytes:1092482370 (1.0 GiB) vnet1 Link encap:Ethernet HWaddr fe:54:00:ed:6a:43 inet6 addr: fe80::fc54:ff:feed:6a43/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:922132 errors:0 dropped:0 overruns:0 frame:0 TX packets:6342375 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:251091242 (239.4 MiB) TX bytes:1629079567 (1.5 GiB) vnet2 Link encap:Ethernet HWaddr fe:54:00:0d:cb:3d inet6 addr: fe80::fc54:ff:fe0d:cb3d/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:9461 errors:0 dropped:0 overruns:0 frame:0 TX packets:665189 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:4990275 (4.7 MiB) TX bytes:49229647 (46.9 MiB) vnet3 Link encap:Ethernet HWaddr fe:54:cd:83:eb:aa inet6 addr: fe80::fc54:cdff:fe83:ebaa/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1649 errors:0 dropped:0 overruns:0 frame:0 TX packets:12177 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:77233 (75.4 KiB) TX bytes:2127934 (2.0 MiB) The guest's /etc/network/interfaces, in this case running Ubuntu 12.04 (ip removed): # This file describes the network interfaces available on your system # and how to activate them.

I have encountered this problem with every guest OS I've tried, that being Fedora, Ubuntu (server/desktop) and Debian with an upgraded kernel. I've also tried compiling the guest kernel myself, to no avail. I have no problem with recompiling a kernel, though the host cannot afford any downtime. Any ideas on this problem are very welcome. EDIT: I can ping the host from inside the guest.
