  • crash when using wireless network

    - by Erik
    ubuntu 12.04 32 bit When I start up my system almost instantly freezes, I found that the problem lays with my wireless network, because the crash is always t the same time as the message that tells me I am connected to a network when I start up connected to a cable everything works fine, I can even see that I am connected to our wireless network, until I unplug the ethernet cable, then it all freezes again the same happened when I boot from a live cd (from usb) The problem only occurs on my netbook, my laptop doesn't give any problems. I don't know if anyone else has had similar problems, or if anyone knows a solution... Thanks in advance! greetings Erik EDIT (21/3/2012): it seems there is some external factor involved, I'm using my netbook for about 50 minutes now while connected to the wireless network, and still it didn't crash strange enough, before these 50 minutes I had to put it down by holding the power button, because I decided to try it again, that time it did crash... before (while connected with an ethernet cable) I've been trying to get my Bluetooth working, that didn't succeed entirely, but I guess that might be a factor in the question why it doesn't crash at the moment now I rebooted, connected, and no crash... if it crashes again, I'll update this post again. in the meantime, if anyone has an idea on what could be a factor, and on how to create a crash using that factor, feel free to ask!

  • Black screen on login, can get thru decrypt disk and access command line but no GUI

    - by t3lf3c
    Running 12.04 64 bit fresh alternative install, with disk crypto on a new Lenovo laptop Install didn't connect and install modules, even though I had the network cable plugged in and don't have any whacky proxy settings. I had to manually install ubunut-desktop and define sources after initial installation, so this seemed a bit weird (ISO matched MD5 sum though) I unplug the network cable, otherwise I get a black screen that I can do nothing with. So I turn laptop on, I have disk encryption, I type in the password at the Ubuntu decryption GUI then get "set up successfully" message "Waiting for network configuration ..." then "Waiting for up to 60 more seconds for network configuration" At this stage (a) If I wait for it then I get a black screen that I can do nothing with. (b) If I interrupt the process by pressing escape, then I break through to the command line. From the command line, I can go ahead and login, then plug my network cable in to do apt-get commands. As a precaution I do some house keeping which takes a few mins to run: sudo apt-get update sudo apt-get upgrade Running startx to get to the GUI gives: Fatal server errror: no screens found The .Xauthority file is being created in my home directory but it's empty. I review my order and note the system graphics: Intel HD Graphics (WWAN or mSATA capable) So it's weird that I can't get to the Gnome. It looks like drivers aren't working. Is there a way of getting Intel drivers from the command line? Or do you have any other suggestions on what to try next?

  • Cat 6 Only 100mbit speed

    - by Stu2000
    I tried two different cat6 cables directly connected between my two ubuntu machines. This one I ordered online: http://www.amazon.co.uk/gp/product/B002SQPDXS/ref=wms_ohs_product only achieves 100mbit speeds, but does appear to be supporting cross-talk (direct pc to pc), the other cat 6 cable, worked perfectly and gets the full 1gigabit speed. Both tests were performed using ftp and checking the network monitor with direct pc to pc connection. Did the product from amazon lie to me or do I need to manually set a setting somewhere in ubuntu for some cables? I had thought 10 quid for 20m of gigabit ethernet cable was a bit cheap, you get what you pay for... Regards, Stu Update: It seems that after rebooting, the device is set to 1000mbit sec when looking it up with sudo ethtool eth0 However after a while, this will drop down to just 100, after which to reset it to 1000 again, I have to reboot, and simply unpugging and re-plugging in the cable doesn't do it. I tried setting this in networking config file as suggested here: auto eth0 iface eth0 inet static pre-up /usr/sbin/ethtool -s eth0 speed 1000 duplex full but that resulted in my networking failing to start. Is there a problem with my 'auto-negotiation' or something? Can I manually override a setting to 1000mbit?

  • 12.04 wired network doesn't work RTL8111/8168B

    - by laket
    its a fresh 12.04 install 64bits. wifi works fine, wired stays off with cable connected and network-manager shows as if cable is disconnected. Turning off networking lights up my network-cards leds, turning networking on shuts off the leds and no communication is possible. I already tried, turning off the network-manager (sudo service network-manager stop) and setting up my eth0 manually, as soon as I switch off the network-manager my leds light up, but after setting up manually eth0 (sudo ifconfig eth0 10.2.10.114 netmask 255.255.0.0 up) the leds turn off again. I am still dual booting with 10.04 where I have no issues at all, leaving the cable connected all time to my notebook and a switch.

  • Boot failure randomly. Can someone help?

    - by desgua
    I often get stuck at the boot on battery. I can suspend and hibernate without any trouble (even on battery). If I plug the energy cable everything goes right most of the time (edited June 13). Adding "acpi=off" doesn't solve the issue. Disabling power save from LAN at BIOS doesn't solve this too. Memory test seems to be ok: I can even compile a kernel without a problem: Has someone a tip for this? (I have the same questions marks in my mind as the image shows if not more :-/ ) obs.: this is an upgraded installation from Natty alpha. edited I (May 22): I've installed a brand new final 11.04 and got the bug again. edited II (June 13): I thought it was solved but it is not. After spending eight days off, the same problem happened even with the power cable connected. I had to reboot about 6 times until success. edited III (June 14): I can boot (even with battery) if I disconnect the cable and take off the battery for a few seconds. This lead me to conclude that maybe something is kept into memory of some hardware. Maybe or maybe not related but I also have touchpad issues (jumps) with this machine. edited IV (June 25): I opened gconf-editor and went to apps gnome-power-manager and disabled everything possibly related to suspend or hibernate. No help. Also I grabbed a Fedora live usb pendrive and got the same problem: So I think it is a hardware problem related issue.

  • Dell M4600 with nVidia Quadro 2000M hangs on boot when external monitor is connected

    - by vladeta
    I have a problem with my fresh installed Ubuntu 12.04 LTS on my Dell M4600: nVidia quadro 2000M i7-2860 16GB ram 128GB SSD Dell/Samsung 750GB HDD IPS RGB laptop display When it is connected via DP++ to the external Dell U2311H monitor, it hangs on boot or when wakening from suspend. If I detach the DP cable it boots normally. I have tried all combinations that I have found, as adding to grub: "no splash", "boot=pci", "acpi=off", etc... I have also changed in nVidia X settings that external monitor is the primary one and also tried to delete monitor.xml file. There is no change it hangs each time after grub. It starts to load daemons then both screens are blank and then completely hangs with beep sound. What I discovered is if I detach the cable and wait for about 2 sec after grub starts booting and then physically connect DP cable while the Ubuntu is still booting everything works normally and I have a picture on my external screen while the laptop screen is off, just as I wanted. Do you maybe know how to solve this issue? Thank You.

  • Horse Drawn Fiber Optics Bring Broadband to Remote Areas

    - by Jason Fitzpatrick
    When you think of fiber optics and high speed internet the last thing you likely think of is… horses. Yet horses have been put to use rolling out fiber optics to remote rural locations. In Vermont a Belgium draft horse named Fred, seen in the photo above being tended by his handler Claude, is a distinctly 19th century solution to a 21st century problem; how to run fiber optic cable through remote areas where trucks cannot easily pass. The man and animal are indispensable to cable and phone-service provider FairPoint Communications because they easily can access hard-to-reach job sites along country roads, which bulky utility trucks often cannot. “It just saves so much work – it would take probably 15 guys to do what Fred and Claude can do,” said Paul Clancy, foreman of a line crew from FairPoint. “They can pull 5,000 feet of cable with no sweat.” You can read more about the use of draft horses to draw lines and the roll out of broadband to rural Vermont at the link below.

  • How to dual boot Ubuntu 12.10 and Windows XP sp3 on Dell Dimension 8250 desktop using 2 hard drives

    - by user106055
    I'd like instructions to dual boot Ubuntu 12.10 and Windows XP (sp3) on my desktop Dell Dimension 8250 (this is old and has 1.5 GB RAM which is maximum). I will be using 2 hard drives. Windows XP is already on a 120 GB drive and and Ubuntu 12.10 will go on a separate 80 GB hard drive. Both drives are IDE using a 80 conductor cable where the 40 pin blue connector connects to the motherboard. The middle connector is gray and is "normally" used for slave (device 1) and the black connector at the very end of the cable is meant for the master drive (device 0) or a single drive if only one is used. First, I do not wish the XP drive to have its boot modified by Ubuntu in any way. It should remain untouched...virgin. Let me know where the XP drive and the Ubuntu drive should be connected based upon the cable I've mentioned above, as well as jumper settings for both during the whole process. I'm just guessing, but should I remove the XP drive and put the empty Ubuntu drive in its place and install Ubuntu? By the way, I already have made the DVD ISO disk. For your information, the BIOS for this machine is version A03. When I tap F12 to get to the boot menu, I have the following choices: Normal (this will take me to a black screen with white type giving me the choice to boot to XP or to my external USB backup recovery drive) Diskette Drive Hard-Disk Drive c: IDE CD-ROM Drive (Note that if the CD Drive is empty, it will then go to the DVD drive) System Setup IDE Drive Diagnostics Boot to Utility Partition (This is Dell's various testing utilities) Thank you in advance for your help.

    Hi All! I'm currently reading "Artificial Intelligence: A Modern Approach" (Russell+Norvig) and "Machine Learning" (Mitchell) - and trying to learn basics of AINN. In order to understand few basic things I have two 'greenhorn' questions: Q1: In a genetic algorithm given the two parents A and B with the chromosomes 001110 and 101101, respectively, which of the following offspring could have resulted from a one-point crossover? a: 001101 b: 001110 Q2: Which of the above offspring could have resulted from a two-point crossover? and why? Please advise.

  • TCP/IP RST being sent differently in different browsers.

    - by Brian
    On Mac OS X (10.6), if I start a YouTube video download and pull the Ethernet cable for 5 or so seconds, then plug it back in, I get varying results depending on the browser. With Opera and Chrome, after I plug the cable back in the video continues to load. But with Safari and Firefox, it never does. Using Wireshark to look at the traffic, I found that Opera and Chrome simply ACK the first packet from YouTube after the cable has been plugged back in, but Safari and Firefox set the RST flag (0x4) in the TCP header and no more traffic follows. I can put a HUB in between the machine and the internet connection, the problem goes away and all four browsers continue loading the video when the cable is plugged back into the HUB. Again, looking at the Wireshark logs, it's evident that the machine doesn't see the Mulitcast connection close and there is simply a delay in the packets flowing through. So it seems that if Safari and Firefox sees a Multicast connection close, and then later see data on that same connection, they will send a RST. My question is why? What is the correct course of action, and why are 2/4 browsers doing it one way, while the other 2/4 are doing it another way? Is there somewhere in the code that I can see where this is happening in Firefox, for instance? Thank you very much.

  • APC UPS replace battery light and apcupsd reporting "replace battery"

    - by mgjk
    We have an APC Smart UPS 1500. The "Replace Battery" light is on, and apcupsd reports: Emergency! Batteries have failed on UPS xxxx. Change them NOW However, from this article, http://sturgeon.apcc.com/kbasewb2.nsf/for+external/f39c4312fcaf7b948525679a005ebb78?OpenDocument it seems that it's not so clear that the UPS battery needs to be replaced. Stranger, according to the information on the UPS, an 11 minute runtime at 42.9% load running at 27.7V isn't so bad. Any thoughts about what to try next? We're a non-profit, money is an object.

  • How to transition to Comcast with static IP address

    - by steveha
    I have my own email server in my house, on a static IP address. I have had business DSL for over a decade, but I also now have Comcast business Internet. I want to transition from the DSL to the Comcast, and I have some questions. I have a domain name, my own mail server, and a firewall (a PC with two network interfaces, running Devil-Linux). I need to make sure I understand how to set up the Comcast cable box, and how to set up my firewall. First, do I need to change any settings in the cable box? Currently I have only used the cable box by plugging in a laptop, with the laptop doing DHCP. I think I can leave the box alone but I would like to make sure. Second, I'm not sure I understand the instructions Comcast gave me for setting up the firewall. My DSL provider gave me the following information: static IP address, net mask, gateway, and two DNS servers. Comcast gave me: static IP address, routable static IP address, net mask, and two DNS servers, and told me to put the "static IP address" as the "gateway" on the firewall. Is this just Comcast-speak here? Does "routable static IP address" mean the same thing as "static IP address" in my DSL setup, the end-point address that I should publish in the DNS MX records for my email server? Or should I publish the "static IP address", and Comcast will then route all its traffic over the cable box? My plan is: first, I'm going to configure another firewall, so I have one firewall for the DSL and one for the Comcast (rather than madly editing settings to switch back and forth). Then I will publish the new Comcast static IP address as a backup email server address in the DNS MX records, wait a while to let it propagate, and then switch my home over from the DSL to the Comcast. Then I'll change DNS to make that the primary mail address and the DSL the secondary, let that go a while and make sure it seems reliable. Then I'll remove the DSL from the DNS MX records completely, and finally shut down the DSL service. (I thought about keeping the DSL as a backup, but the reason I'm leaving DSL is that it has become unreliable; and I have heard that Comcast business Internet is reliable.) Final question, any advice for me? Anything you think might be useful, helpful, or educational. Thanks.

  • Daisy-chaining network switches with multiple cables

    - by user72153
    This might just be the dumbest question you'll ever read, but I digress. Say I have two 100Mbps Ethernet switches with 2 computers on each, connected together by a single cable. This way, the two PCs on each switch share the 100Mbps bandwidth with the others. If I added another cable between the 2 switches, would there be 200Mbps throughput available between the switches? Or am I completely off my rocker? Thanks for the help.

  • Need to Connect 2 HDMI between Onboard and Add-In GPUs - What's the consequences?

    - by jmalais
    If i plug a second hdmi cable into my onboard video output (my dedicated add-in only has one hdmi port) will it use my video card or the onboard for that display? Also, what is the difference in quality between HDMI and DVI? I do have a DVI to HDMI adapter and cable that I could use alternatively if the above is not in my best interest. This is a gaming related question as I will be gaming off the two displays, hopefully in the highest of quality.

  • Optical multicast

    - by Randomblue
    I have a 10G XPF+ optical cable with market updates from a stock exchange. This cable goes into a switch, which then multicasts every packet to a couple of computers. The problem with using a switch for multicast is that there is latency overhead, even with a pass-through switch (~200ns). Are there "optical" solutions (I'm thinking of a beam splitter of some sort) which would allow for close to zero latency 10G multicast?

  • Access Home Network Server via External Address

    - by Dominic Barnes
    For the last few months, I've been using a server on my home network for basic backups and hosting some small websites. Up until this past week, I've been using Comcast (cable) as an ISP and now that I've moved into an apartment, I'm using AT&T. (DSL) I've set up dynamic DNS and I can verify it works externally. However, I can't seem to access the public address from within the local network. Is there something DSL does differently from Cable that makes this frustration possible?

  • Looking for a fiber optic "switch" or "router" for home use

    - by Shrout1
    The gist of my question: What is a "fiber optic" switch called? I.E. a layer 2 ethernet switch that uses fiber TX and RX connections and sends layer 2 network traffic between the fiber strands that are connected. Can someone purchase a dedicated fiber switch that does not have copper ethernet ports? What is the current average price of a device like this? Not necessarily looking for product endorsements, just information Might not make sense to go this route if it is too cost prohibitive What type of fiber connector is used for terminating a fiber strand into a jack on the wall? Can fiber be "patched" using two jacks and a "patch" cable? Is signal loss a concern with the longest runs at 100-200ft, a patch cable and media converters? The full story: My parents had unterminated fiber optic cable and terminated Cat5e run throughout their home when it was built in 2004. 10 years later the Cat5e isn't providing the throughput that my father needs to accomplish multiple streams of HD and fast system backups throughout the house. He can't reach gigabit speeds across the distance of the Cat5e runs. We are both interested in terminating the fiber connections and using them as high speed "backbones" to copper switches in each room of the house. It would be easy to attain gigabit speeds (or better, eventually) using the fiber. I have searched and searched for a "fiber optic switch" or "fiber optic router" and cannot find the correct term to describe this piece of hardware. We can use fiber media converters at the end points of each connection, however it would be nice to have a "patch panel" set up in the network closet in the basement that has fiber connections on it and switches the ethernet streams between the connections/systems in the house. Each fiber media converter costs between $50-$100 a piece... After 10 or so terminated connections it might make sense to find a piece of hardware that does not require media converters. That would depend upon the cost of this hardware Somewhat unrelated, if we are able to route between these fiber strands successfully, what is the physical connector type used in a jack on the wall? Just like RJ45 has a wall outlet (depicted below): What is the fiber optic equivalent of this? In the interim could we "patch" a couple fiber strands together in the network closet?
