  • NVIDIA Additional Drivers Empty - maximum resolution 640x480 - Driver disappears

    - by Hannibal
    EDIT: Optimus card. For resolution please read this thread: "You do not appear to be using the nvidia x server"(screenshot included) And this: Ubuntu 11.10 problem with Nvidia Thanks! I know, I know yet another NVIDIA question. So I did all the research. I uninstalled and installed nvidia-settings and drivers and nvidia-current from PPE repositories which are the most updated ones. I executed nvidia-xconfig. I have two major problems. One: Additional Drivers setting is empty! It doesn't contain any driver although one is installed. I have executed apt-get update too. But still the list is empty. Two: If I execute nvidia-xconfig it will properly configure an xorg.conf file. I restart but the maximum resolution I got is 640x480. I tried the xrandr but I can't add any resolution to display LVDS1. Some weird error occurs. So I can't add a proprietary driver and I can't boot in with the xorg file created by Nvidia... What can I do? With some work ( unistall nvidia-current and install libgl1-mesa-glx I was able to activate some kind of usage of my card because the resolution got better... and I added bumbelbee to because I have multiple video cards... ) but still the list is empty. I don't know what to do at this point??!!! Also: this is the most important part. When I first installed my ubuntu yesterday 11.10 one I saw the driver!! The driver was there... And then I ofc updated every package from internet.. And after that it was gone. And I can't bring it back. So there must be something wrong with one of the updates. But which???? Thanks for any extra info you can provide! I'm really desperate to solve this issue.

  • RouterOS on Hyper-V (v3/2012) - any way to get it working?

    - by TomTom
    Trying to set up a small VPN point to connect into a remote Hyper-V cluster using ROuterOS. Anyone got it working ON Hyper-V with the latest builds of RouterOS? It seems the legacy network adapter is not supported anymore either (or just broken). The platform is a Windows Server 2012 RC. This is not a high performance setup - the RouterOS wont do the routing for more than the backend administrative access, and the only real traffic we will see there is when ISO images for new operating systems are uploaded. Otherwise we will have possibly RDP traffic as well as web / http traffioc, but this is internal only (dashboards, some control panel). The server has no public business. So the price for non virtualized network cards is ok for me. After hooking up - ping just does not work. After some time I see in windows (arp -a on the command line), so I know that the Hyper-V side is set up properly. Just no packets arrived. I have turned off all protection on Hyper-V (or : not turned them on), so no MAC spoofing protection etc. in the Advanced page for the legacy adapters. Unless I can get it work I will have to resort to using a windows install as router / VPN endpoint, which introduces another OS into the fabric (we run all routers etc. so far on mikrotik in hardware, which is why I want this one to be RouterOS, too). And no, putting hardware there is NOT an option - the cost would be significant.

  • Watchguard Firewall WebBlocker Regular Expression for Multiple Domains?

    - by Eric
    I'm pretty sure this is really a regex question, so you can skip to REGEX QUESTION if you want to skip the background. Our primary firewall is a Watchguard X750e running Fireware XTM v11.2. We're using webblocker to block most of the categories, and I'm allowing needed sites as they arise. Some sites are simple to add as exceptions, like Pandora radio. That one is just a pattern matched exception with "padnora.com/" as the pattern. All traffic from anywhere on pandora.com is allowed. I'm running into trouble on more sophisticated domains that reference content off of their base domains. We'll take GrooveShark as a sample. If you go to http://grooveshark.com/ and view page source, you'll see hrefs referring to gs-cdn.net as well as grooveshar.com. So adding a WebBlocker exception to grooveshark.com/ is not effective, and I have to add a second rule allowing gs-cdn.net/ as well. I see that the WebBlocker allows regex rules, so what I'd like to do in situations like this is create a single regex rule that allows traffic to all the needed domains. REGEX QUESTION: I'd like to try a regex that matches grooveshark.com/ and gs-cdn.net/. If anybody can help me write that regex, I'd appreciate it. Here is what is in the WatchGuard documentation from that section: Regular expression Regular expression matches use a Perl-compatible regular expression to make a match. For example, .[onc][eor][gtm] matches .org, .net, .com, or any other three-letter combination of one letter from each bracket, in order. Be sure to drop the leading “http://” Supports wild cards used in shell script. For example, the expression “(www)?.watchguard.[com|org|net]” will match URL paths including www.watchguard.com, www.watchguard.net, and www.watchguard.org. Thanks all!

  • Why does my Intel HDA onboard sound card not have a "Mix" device / channel?

    - by Hanno Fietz
    I want to be able to record what my sound card outputs on the speakers / headphones. This question is all over the interwebs again and again, and there seem to be two outcomes: in your selection of audio input devices, there's a device called "Stereo Mix", or similar, which is the "loopback" device for audio. Choose that in your recording tool and you're done. there's no such device and only speculative posts about why that may be. Now, I'm using ALSA and an Intel HDA chipset on my mainboard under Kubuntu Karmic. I have some 5-10 output channels and "Mic", "Front Mic" and "Line" for input. All of those are available in KMix, Audacity and other software. No "loopback" / "Mix" / whatever. Do I have to get some driver / kernel module set up ALSA in some way set up my system configuration in some way use a software solution (such as JACK) I had a look at JACK, and found it rather hard to understand, it's either an expert tool or just clumsy, I couldn't say. At least, I wasn't able to figure out how to achieve what I wanted. One of my problems seems to be that I don't understand where and how the mixing happens. Are there sound cards which just aren't able to do it? Why does the sound card matter at all, since I could in theory grab the data stream at some point before it goes to the hardware, right?

  • Intel 1.83 Mac Mini upgraded to 1.5 gig for Snow Leopard

    - by Paula
    Even though I've upgraded countless video cards, RAM, harddrives, motherboards in PCs... this will be my first mac mini RAM upgrade. I've watched the classic "putty knife" video. (Absurd method... but I guess it's what I'm stuck with.) I have a 1.83 Intel-based Mac Mini from 2007-2008, with 1 gig of RAM. (Two 512 sticks) Can I install 1 gig + 512 ? (Or do I have to throw away my existing sticks and buy two 1 gig sticks?) This old machine is rarely used... so I want to spend the absolute minimum on this RAM upgrade. We ONLY use it to run xCode... nothing more. But wanted to increase the RAM so we can install Snow Leopard. I have no idea how many pins the memory has. I printed out over FORTY pages of specs about this machine from "About this Mac"... but didn't find what I needed. Does this sound right: DDR2 SDRAM (but no mention of SO-DIMM) 667MHZ (but don't know if I can use faster also) Pin count: Unknown Computer model number: Unknown (But I "think" it's an MB138/A) PC2 RAM (unknown... not mentioned) 5300 (unknown... not mentioned) Mfg date: (unknown... not mentioned) Number of slots: (unknown... not mentioned) Laptop or desktop RAM: (unknown... not mentioned)

  • BSOD Before Windows Will Loads - Graphics Related

    - by Brian
    Alright deep breath here: (Windows 7 Home Premium 64 bit btw) Today I installed Star Craft 2 Beta. After trying to log in, it had some issues where it said my device stopped working (referring to my video device I have to imagine). After I force quit the game there were some random "hot" (various colors if i remember correctly) pixels on the screen. I decided to reboot and try again with similar results. I figured that maybe my display drivers could stand to be updated (I don't frequently update them as I don't often run into problems). I went out to nVidia's website and grabbed the latest drivers for Windows 7 64 bit GeForce 9 series. (I have SLi-ed 9800 GTs). Everything seemed to install fine and I performed the restart. This is when things went from bad (can't play SC2 beta ;) ) to worse (can't boot into windows!). Initially the very first splash screen - I think it's the bios splash screen - had lines of colored pixels covering it. It then displayed a screen that had lots of "(" on it. After that it showed the normal windows 7 splash screen as if it were going to load into Windows. Before getting much further, it BSODed on me. It was a 0x0000003B stop error. At nvlddmkm.sys. A little digging let verified that this was a problem with an nVidia graphics device, not a real shocker. Windows decided it would try to help me diagnose the problem, which it's only answer to was a System Restore, which did nothing to alleviate the problem. I was able to boot up fine in safe mode and was not able to roll back the driver, however I did uninstall the driver and reboot. I still had the graphical anomalies during the first two screens (same colored "."'s and weird "("'s), but there was NOT a stop error. Windows loaded up, found a default driver for the device and installed it and I restarted to let it load - and had yet another BSOD Stop error. Repeat driver uninstall, this time I reloaded the same version (I think it's possible that I was running a 32 bit version or a vista versus windows 7 version, but I don't have that information handy) of the nVidia driver from their website. Restart, same anomalies, same Stop Error. I am at a loss - At this point all I can think is that the firmware for the Video cards got fried or there's actual damage to the cards which I sincerely hope is not the case but the sooner I know the better. Any insight into what I might be able to do to troubleshoot/fix this problem would be most helpful. Attached below is a dump from DxDiag.

  • Cisco ASA Act as a Hardware Security Module?

    - by Derek
    Hello, We have a partner that is requiring us to get a HSM for a web application that we host for them. This is something new for us, we've always installed our SSL certificates on our web servers and never needed a hardware device. We currently have 2 Cisco ASA 5510 firewalls in an active/standby configuration. Both ASAs have a ASA-SSM-10 security module installed in them. The web application is a standard HTTPS webpage with no authentication required. I was wondering if we could use our Cisco ASAs to meet this requirement or if we'll have to buy another device. I was doing some searching and read about Cisco's clientless webvpn feature. It sounds like it might work, but I'm not sure. We basically want the ASA to handle the SSL and proxy the connection to our web servers. We do not want to prompt for a username or password to connect or show any portals, just display the web page. If the ASA cannot do this, does any one have any recommendations for network attached hardware security modules? We are using VMware vCenter, so we'd rather have an external device attached to the network, rather than buying HSM cards for every ESXi host. Thanks, Derek

  • Disabling DNS Registration on Server 2008 R2

    - by WaldenL
    I want to tell a server 2008 R2 machine to NOT register it's IP addresses in DNS. I go into the Advanced tab on IPv4 and turn off "Register this connection's addresses in DNS" simple! But... the addresses are updated in DNS anyway! And actually the A record is eventually removed from the DNS server. I've confirmed that the checkbox is off by looking at it myself, and by checking the RegistrationEnabled registry value for that adapter. Both confirm that the registration is off. I've turned of DNS debug logging on the DNS server and I can see DNS Update requests coming from the server in question! This should not happen. What's even odder is that eventually (several hours) the A record for the server (which I added by hand!) is removed from the DNS server. I've also confirmed that scavaging is off on both DNS servers in the domain. Ideas? Edits: Per the comment: The server has static IP addresses. However, it's got two of them on one adapter. Since I'm in a VM (HyperV) environment I just spun up a second adapter and moved the second IP to the second adapter. I set the first adapter to auto-register (since that's the IP I want anyway) and the second adapter to NOT auto-register. We'll see if this is any better. Not any better. On a reboot of the server the registration was removed from DNS. Seems both cards are still contacting the server. Based on the DNS log the card that shouldn't register in DNS is registering a 'delete' request. And then the card that should register is registering an add request but that's ignored. I'm totally confused at this point.

  • "Modern" Ethernet over coax

    - by Electrons_Ahoy
    So, I've just bought a house. It's reasonably new - built in the early '00s. One of the features that got built in was a cable TV drop in every room. The cabling is gorgeous - there's even a wiring cabinet of sorts in a closet where the cables all tie together to the splitter to the outside line. Of course, my problem is that I only own the one TV. I do, however, own a few computers. What I would love to be able to do is drop a switch in the wiring closet and run 100/1000BASE-T ethernet over the coax in the walls I wouldn't otherwise be using. My fantasy would be if you could get some kind of adapter-plug-thing that would take a coax plug on one side and a cat5/RJ45 plug on the other. Had anyone else done this? Any suggestions? (There are a few other options that suggest themselves - first, I could just use the existing cabling channels and re-run cat5 or 6 through the walls. While tempting, that sounds like more work than I really want to put in, so I'm calling that Plan B. Also, I could just scare up a mess of old 10BASE2 cards and run the house on thinnet, all mid-90s style. While I think I'd get major style points for that, I don't think I can get a 10BASE2 adapter for the new laptop. Also, I have all these super-snazzy gigabit adaptors I'd like to be using. And so forth.)

  • Strange performance issue with Dell R7610 and LSI 2208 RAID controller

    - by GregC
    Connecting controller to any of the three PCIe x16 slots yield choppy read performance around 750 MB/sec Lowly PCIe x4 slot yields steady 1.2 GB/sec read Given same files, same Windows Server 2008 R2 OS, same RAID6 24-disk Seagate ES.2 3TB array on LSI 9286-8e, same Dell R7610 Precision Workstation with A03 BIOS, same W5000 graphics card (no other cards), same settings etc. I see super-low CPU utilization in both cases. SiSoft Sandra reports x8 at 5GT/sec in x16 slot, and x4 at 5GT/sec in x4 slot, as expected. I'd like to be able to rely on the sheer speed of x16 slots. What gives? What can I try? Any ideas? Please assist Cross-posted from http://en.community.dell.com/support-forums/desktop/f/3514/t/19526990.aspx Follow-up information We did some more performance testing with reading from 8 SSDs, connected directly (without an expander chip). This means that both SAS cables were utilized. We saw nearly double performance, but it varied from run to run: {2.0, 1.8, 1.6, and 1.4 GB/sec were observed, then performance jumped back up to 2.0}. The SSD RAID0 tests were conducted in a x16 PCIe slot, all other variables kept the same. It seems to me that we were getting double the performance of HDD-based RAID6 array. Just for reference: maximum possible read burst speed over single channel of SAS 6Gb/sec is 570 MB/sec due to 8b/10b encoding and protocol limitations (SAS cable provides four such channels).

  • How to run Android-x86 project's ISO in VirtualBox with ethernet?

    - by Shiki
    I managed to find a way just days ago, but I had to leave my other PC and now I have no clue how to get it working again. Basically you have to get the image, then install it in a VirtualBox guest. Now the problem is ... when you launch your VM, there is no internet connection. No with NAT or Bridged. Tried all the network cards too. Since internet connection is crucial for Android development, I have to get this thing working. (As I said, I managed to fix it once.) I'm using: - The 4.0 RC1 images from Android-x86 - VirtualBox - Eclipse 4.2 Juno with the latest Android ADT - Android SDK v18 - upgraded to 19 via the Package manager. Now I seen a lot of different builds on the net, about different Android builds for VirtualBox. I have checked Buildroid for example, but there is no network connection. I have imported the virtual machine just as the howto said. The extension package is also installed and it's up to date.

  • Ubuntu 12.4 compiz - disable all compiz plugin - empty screen

    - by gotqn
    A friend of mine has installed on my new machine Ubuntu 10.4 (I have always been windows user and have no experience with Linux). I started to watch some tutorial about how to make 'Rotated Cube' using 'Compiz',but the cube appears in the form of a list (only two slides). I have thought this could be result of my video cards (only two - one from the processor and one from the motherboard) and they can not support this options. Anyway, I have decided to disable all compiz plugins and options because my friend has set some, and I started to think there is some misunderstanding between the plugins. After, that I got only empty screen(no menu, no icons, anything) and can do nothing. How to fix this? EDIT: When I remove the compiz stuffs (from the console), the menu is shown again. Then I install the compiz again (some of the effect are still not working). After restart or log out/in the menu is hidden again. I suppose that there are some settings that I've broken but they are saved somewhere in the system and remove the compiz do not deleted them and as a result they are activated after compiz is installed again and the PC is restarted?

  • Distribute IP packets accross different NIC queues with MSI (Message Signalled Interrupts)

    - by Ansis Atteka
    NetXtreme II BCM5709 Gigabit Ethernet NIC supports MSI feature (Message Signaled Interrupts) and it has 8 queues. Each queue has its own Interrupt handler in /proc/interrupts. What I am trying to accomplish is to tell NIC which packets should go to which queue. Questions: Is it possible to manually specify which IP packets should go to which queue by encapsulated protocol type (e.g. IPsec packets go in one queue, while TCP packets go in another queue)? If it is possible - how can I do it under Linux? If it is not possible - should I look at MSI-X capable NIC cards to solve this problem? More details: We have one Interface that is terminating IPSec and forwarding/terminating TCP connections. The IPSec packet decryption is inlined (this means that decryption is done under the same ksoftirqd/X context). We are trying to find out if we will be able to improve total performance if IPSec packets will be scheduled on another CPU than TCP packets. One more limitation is that IPSec code is not MP-safe, hence I can not run it under more than one ksoftirqd/X. By default it seems that packets are distributed/hashed by source IP over the 8 NIC queues. The bottleneck is IPSec that chokes out TCP traffic while it is decrypting/encrypting IPSec packets at ~100% CPU. OS is Ubuntu 10.10 (2.6.32-27-server) and NIC is Broadcom BCM5709.

  • New Computer freezing up at random

    - by Benjamin Frost
    Since I built my system about 4 weeks ago I'v been getting random freezes, Sometimes it can happen directly after startup and sometimes it wont freeze up for 3-4 days of 24/7 running. It seems to be happening under all stress loads but mainly when the CPU is under 10% load. It doesn't give me a BSOD or anything, it simply just freezes and repeats the last sound before the freeze until I shut it down by the power button. I'v re-seated everything in the system except the CPU, Cleaned the RAM sockets and gold fittings. None of the components have been clocked above their factory settings as of yet, don't want to overclock them until I sort out these freezes. Temps are all well under the rated max temps, the highest the temps have been are below CPU: Low load: 16-21°C Full Load (100%) 40-43°C *(From HWMonitor by CPUID) GPU 1: Low Load: 25-30°C Full Load (100%): 45-50°C GPU 2: Low Load: 23-27°C Full Load (100%): 45-50°C *(GPU Temps from Catalyst Control Center) General Case temps Rear: 18-20°C Mid: 20-21°C Front (HDD/SSD Bays): 14-19°C (Case temps may be a little off as it's from the Kaze master pro fan controller) I have Un-installed EVERY driver for Motherboard, GPU & Soundcard and Re-installed twice.

  • Failed to bring up eth1 in a dual ips solution in ubuntu

    - by lxyu
    I'm using ubuntu 12.04. I tried to assign two ips to two ethernet cards in my server. The content of /etc/network/interfaces is like this: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 114.80.156.a netmask 255.255.255.224 gateway 114.80.156.b auto eth1 iface eth1 inet static address 114.80.156.c netmask 255.255.255.240 gateway 114.80.156.d a b c d have different values, which means the two ips are in different vlans. But I can only bring up eth0 with this command: $ /etc/init.d/networking restart RTNETLINK answers: File exists Failed to bring up eth1. ...done. I have checked the question here which shows the same problem like the one I encountered: Can only bring up one of two interfaces But it seems it's not really solved. And in my situation, I need the 2 ips to use 2 different gateways. So how to fix this problem? Edit1, changed the example config ip from 192.168.0.0/16 subnet to another 'real' subnet. Edit2, the purpose of doing this is fairly simple. Because the ip range I previous in don't have more room for new servers, and I have to move to another ip range. So I want to make the public servers bind to 2 ips for the transition period. I only have really limited knowledge about routing and subnet. @BillThor @rackandboneman, would you please give me some keywords or links on how to setup route for 2 ips? and @Mike Pennington, how do you know I speak chinese?

  • Computer does not switch on after power outage

    - by cristian
    VOLTAGE DROP OFF FOR PC does not restart The other day my pc was turned off due to power outage. Since that time the computer would not turn on again, no sign of life, it seems dead. I did several tests, changed the power outlet and disconnect the wires ... also I have reseated the cards ... but the result is that nothing changes. What can I do? Could there may be damage to the hardware due to the power outage? Note: the voltage drop is not due to a lightning storm and so is not due to damaged components (burnt card etc ...) Original Text: l'altro giorno il pc mi si è spento improvvisamente per calo tensione.... da quel momento non si è piu' riacceso...nessun segnale di vita...sembra proprio morto. Ho fatto diverse prove, cambio presa di alimentazione, scollegare i fili...insomma ho "mischiato le carte"...ma il risultato è che non cambia nulla. Cosa posso fare? cosa puo' essere successo? Possono esserci danni hardware per il calo di tensione? NB: il calo di tensione non e' dovuto ad una saetta e quindi escluderei danni causa temporale (bruciature scheda ecc...) Grazie mille

  • What is optimal hardware configuration for heavy load LAMP application

    - by Piotr K.
    I need to run Linux-Apache-PHP-MySQL application (Moodle e-learning platform) for a large number of concurrent users - I am aiming 5000 users. By concurrent I mean that 5000 people should be able to work with the application at the same time. "Work" means not only do database reads but writes as well. The application is not very typical, since it is doing a lot of inserts/updates on the database, so caching techniques are not helping to much. We are using InnoDB storage engine. In addition application is not written with performance in mind. For instance one Apache thread usually occupies about 30-50 MB of RAM. I would be greatful for information what hardware is needed to build scalable configuration that is able to handle this kind of load. We are using right now two HP DLG 380 with two 4 core processors which are able to handle much lower load (typically 300-500 concurrent users). Is it reasonable to invest in this kind of boxes and build cluster using them or is it better to go with some more high-end hardware? I am particularly curious how many and how powerful servers are needed (number of processors/cores, size of RAM) what network equipment should be used (what kind of switches, network cards) any other hardware, like particular disc storage solutions, etc, that are needed Another thing is how to put together everything, that is what is the most optimal architecture. Clustering with MySQL is rather hard (people are complaining about MySQL Cluster, even here on Stackoverflow).

  • ProCurve network expansion

    - by Blue Warrior NFB
    I've hit a bit of a wall with our network scale-out. As it stands right now: We have five ProCurve 2910al switches connected as above, but with 10GbE connections (two CX4, two fiber). This fully populates the central switch above, there will be no more 10GbE Ethernet connections from that device. This group of switches is not stacked (no stack directive). Sometime in the next two or three months I'll need to add a sixth, and I'm not sure how deep of a hole I'm in. Ideally I'd replace the core switch with something more capable and has more 10GbE ports. However, that's a major outage and that requires special scheduling. The two edge switches connected via fiber have dual-port 10GbE cards in them, so I could physically put another switch on the far end of one of those. I don't know how much of a good or bad idea that would be though. Is that too many segments between end-points? Some config-excerpts: Running configuration: ; J9147A Configuration Editor; Created on release #W.14.49 hostname "REDACTED-SW01" time timezone 120 module 1 type J9147A module 2 type J9008A module 3 type J9149A no stack trunk B1 Trk3 Trunk trunk B2 Trk4 Trunk trunk A1 Trk11 Trunk trunk A2 Trk12 Trunk vlan 15 name "VM-MGMT" untagged Trk2,Trk5,Trk7 ip helper-address 10.1.10.4 ip address 10.1.11.1 255.255.255.0 tagged 37-40,Trk3-Trk4,Trk11-Trk12 jumbo ip proxy-arp exit

  • LAN network (switch?)

    - by guywhoneedsahand
    I am working on setting up the network for a small LAN party (less than 16 people). Most of them do not have wireless cards in their rigs, so I need to set up some way for everyone to a) play LAN games and b) access the internet. The LAN party will probably take place in my basement, where I have enough space. However, the basement is not wired up with the router which is actually on the floor above. I make a cantenna a while back that can boost the wireless performance of my computer significantly. How can I use this to provide internet and LAN to guests? My hope was that I could use a switch like this http://www.newegg.com/Product/Product.aspx?Item=N82E16833181166 for the LAN - but how can I give people access to the internet? Is there such thing as a network extender / 16-port switch? Obviously, the internet performance doesn't need to be super stellar, because the games will be using LAN - so I am looking to provide some usable internet for web browsing, and very high speed LAN for games. Thanks!

  • fax server farm architechture

    - by Brian Postow
    I'm not sure this is the right forum for this, but it's not Stackoverflow so... I'm trying to figure out an architecture to solve the following problem, maybe someone here can help: I have a T1 with 23 fax lines coming into the building. I have a computer (Macintosh XServe) running Hylafax. If I had one POTS line, I'd be done. However, I have no idea how to get the T1 into the Mac... Options I've considered: some sort of PCI T1-modem (Does that exist?) Splitting the T1 into 23 POTS lines and then connecting 23 analog modems to the mac, either via an external modem bank (Do they still make those?) or via some sort of external PCI bank, which will allow me to use more than 2 4-port modem cards. Either the T1 or the split POTS lines going into some intermediate device and then transfering the images over IP, or USB to the mac. Really, any other option I can come up with This has GOT to be a problem that someone has already solved, right?

  • RRAS NAT not working on a certain computer

    - by legenden
    This is driving me crazy. I have a virtualized W2K8 server running RRAS. Every other computer or server on the network can access the internet through the NAT except one. On one server, it just won't work. I can ping the ip address of the NAT gateway just fine, and everything else works. (SMB, etc) DNS, which is hosted by the same server, also works just fine. I have even reinstalled the OS on the problem server and it still doesn't work. Recap of the steps I tried: There are 3 network cards in the server, I tried every one and different switch ports. Not a hardware problem. Reinstalled W2K8 R2 on server with the problem, didn't help. Tried the IP of the internet gateway directly - this did work (!). But I need NAT to work. All firewalls are disabled. Removed computer from domain, deleted computer membership in Active Directory Users and Computers and added it back. Disabled all other network adapters and set a static ip and specified the gateway ip manually. When I tracert a public IP, the first hop (or any other hop) comes up as: C:\>tracert www.google.com Tracing route to www.l.google.com [209.85.225.106] over a maximum of 30 hops: 1 * * * Request timed out. 2 * * * Request timed out. From a different computer, on which NAT works, the first hop comes up as: tracert www.google.com Tracing route to www.l.google.com [209.85.225.105] over a maximum of 30 hops: 1 <1 ms * <1 ms xxxx [10.5.1.1] This is the most bizarre problem I ever came across, and I realize that it's a long shot asking it here given all the details, but I'm pulling my hair out. Maybe someone has an idea...

  • BIOS corrupted? How to proceed? Acer Travelmate 290

    - by dtlussier
    I have a older ACER Travelmate 290 (manufactured in 2002 or 2003), which I recently tried to upgrade to Ubuntu 9.10. After doing the upgrade process it appeared as if I had a problem with my x server configuration, as on the first reboot post-install I heard the Ubuntu startup sound, but had a black screen. I thought I would then reboot again to drop down into text-mode to trouble shoot the x configuration problem. However, when I tried rebooting, something went wrong and since then when I start up the machine I get absolutely nothing except the first hardware check (i.e. HDD light flashes, CD/DVD drive spins, etc.). Other than that the screen remains totally black and I have no HDD or processor activity at all. I have tried restarting it a number of time holding down all kinds of key combinations to try and coax it into the BIOS (if possible) with no luck. I have also tried putting in both a live Linux disc and a Windows install disk without any luck. With a disk in the drive it will spin for a few seconds and then stop. All this has lead me to suspect that the BIOS is somehow corrupt (not sure about the right terminology). I have tried putting a new BIOS image and installer program downloaded from ACER on a USB key to see if it will run when I start up the machine, but no luck. I'm not sure if this method of interacting/updating/flashing the BIOS will work outside of Windows/DOS as both OSs are mentioned kind of ambiguously in the documentation. I have also taken the laptop case apart and inspected the various cards and cannot find any obviously burned out components. I'm not sure how to proceed at this point in terms of components to try, or how to try and load a new BIOS image onto the board. Any advice here would be great, especially from those with experience with this particular line of laptops. Thanks!

  • Audio card with built-in ground isolator?

    - by Dave Jarvis
    What audio cards would you recommend that eliminate hum, and hard-drive & mouse movement signal interference? Hardware components: Motherboard. Asus P5Q SE Audio. Realtek ALC 1200, 8-Channel High-Definition Audio CODEC (on board) Harddrive. WD Caviar 320 GB Mouse. Logitech Marbleman USB Mixer. Mackie d.4 Pro Amplifier. Sonance Sonamp 260 All components are plugged into the same Monster Power HDP 910 powerbar (does not help eliminate noise). I have no other components plugged in. The computer uses a Monster iCable 1000 to go from mini (on board audio) to RCA (mixer). I have moved the cable as far from other cables as possible. A ground loop isolator between the mixer and on board audio eliminates all noise. I would rather not use a ground loop isolator; an internal audio card that is Linux-compatible (Kubuntu) would be ideal. Suggestions?

  • Problem importing pictures from a digital camera with Windows 7

    - by snark
    Hi, Since I'm using Windows 7 (Beta, then RC, now RTM), I have issues when I download pictures from my digital cameras. It happens with my 2 cameras: a Canon Powershot S2 IS and a Canon Ixus 80 IS. When I plug a camera (any of them) to a USB port and switch it on in Play mode, the Autoplay function of Windows 7 starts with this screen: I select "Import pictures and videos" to call the native Windows 7 tool. It searches a bit for pictures to download from the camera and starts the transfer. However, during the transfer, I often get errors like this one: If I use "Try again", it works fine the second time and the picture is retrieved correctly. It's very annoying when it happens 20 or 30 times in a 500-picture download. I cannot leave it running standalone, as I have to watch for the errors and click on "Try again". Any idea what is causing these errors? I tried changing the USB port (normally the cameras are connected via a USB hub but it happens also when I connect them directly to a MB USB port) and the USB cable, but no success. I also checked the SD card by connecting them with a card reader and running a ChkDsk on them but it found no errors on the cards. Update: No problem when I copy the pictures manually with the Windows Explorer. And no problem either when I access the card with a reader. The builtin import tool of Windows is convenient as it sorts the pictures automatically by date (1 folder per day). And this is the way I sort my pictures
