• Windows XP Setup Fails to Recognize USB Floppy after formatting AHCI disk

  - by Strahn

  I am attempting to install Windows XP Professional x64 onto a HP EliteBook 8540w. I have downloaded both the latest Intel Rapid Storage Technology drivers and the Intel Storage Matrix drivers that are listed on HPs website and copied the drivers over to a floppy disk (two separate floppies, one for each version of the drivers.) Booting to my WinXP Pro x64 install CD, I go through the F6 process, load the driver and am able to see my HDD, delete, create and format partitions on it. When I go to continue the install, after checking the disk, the system asks me to enter the disk labeled "Intel Rapid Storage Technology" and press enter to continue. Nothing happens at this point when I press enter. This happens if I use the latest drivers or the older drivers. We have created a slipstreamed install CD using nLite that has the AHCI drivers integrated, which installs fine. However, we have identified a number of issues with the system that I believe are side-effects of using nLite for the slipstreaming and I am attempting to verify that. I have researched this issue and found a few examples of others having the same problem, but no solution. The USB floppy is a Lacie branded floppy, connecting it to a working XP workstation shows it to be the Y-E Data USB floppy drive that is supposedly 100% compatible with XP per MS KB 916196.

• "Safely remove hardware"...doesn't.

  - by Kev

  I have an external USB harddisk that I have scripted to safely shut down after a backup, so the backup operator can unplug it, and knows not to if the lights are still on for some reason. It's always worked fine using the DevEject command-line utility. This week it failed for some reason: DevEject 1.0 2003 c't/Matthias Withopf Ejecting 'USB Mass Storage Device' [USB\VID_0411&PID_002A\00000704C8D2]...FAILED (23,5) Error ejecting device USB Mass Storage Device, vetoed (15,5)! Worse yet, using the SRH tray icon, I click Stop, click OK, it pauses about 5 seconds with OK and Cancel greyed out, closes the sub-window, and then the main window with the Stop button still shows the device, and Stop is still available. I can keep doing that and it never gets rid of the device. I can still access it in Explorer. LockHunter reports that nothing is locking the drive. I've made no changes to the backup configuration or anything to do with the drive this week. Why the sudden flake-out? Short of a restart, which I can't do today before the backup operator goes home, how do I fix it?

• MGE UPS Cut power - What happened?

  - by JT.WK

  I have 3 x MGE Pulsar M 3000 2700w UPS units within my server room which have run perfectly up until now. On Saturday morning I noticed that one of these UPS units was no longer outputting power, the lcd displayed a message saying "load not powered" and told me to press the power button to start output. Needless to say that the servers, switches and routers is was supporting were all turned off. I tried pressing and even holding the power button, but the unit refused to start back up again. Only power cycling the unit got it back up again. I have checked the logs on the UPS, although they were useless. Nothing out of the ordinary, and no email notifications had been sent. The output level sits on about 51% and all battery checks are OK. It is now three days on and the UPS is still up and running (although I am scheduling an outage to get it out of there ASAP). Does anyone have any idea what could have gone wrong here? Is there anything else that I can check that could help?

• Eee PC Seashell series netbook screen is cut off at bottom no matter the resolution

  - by Yzmir Ramirez

  I have an Eee PC 1015PE Seashell netbook running Windows 7 Home Premium with an Intel Graphics Media Accelerator 3150 (8.14.10.2230) with a "Generic Non-PnP Monitor" detected. I tried: Changing the resolution (Control Panel = Appearance and Personalization = Display = Screen Resolution) to 1024x768 Updating the video driver (to 8.14.10.2230) Uninstalling the driver and rebooting Pressing the Windows Key + "-" (magnifier) Pressing Ctrl + Mouse Scroll only resizes the desktop items Pressing Fn + F4 shows 1024x600 (which I think is what I should be using, but nothing happens) EDIT: Changed from Landscape to Portrait and it works Attached an External Monitor and when I extend or set as desktop it works only on the External Monitor (shows up as "Generic PnP Monitor in Device Manager) Basically the bottom inch of my desktop is off-screen hiding my start bar, but my wigets are in their proper position (the start bar is not hidden). Pressing Ctrl + Esc shows the start menu but its cut-off. I'm pretty sure I should be using 1024x600 resolution, any advice? What's odd is that this only started happening recently. EDIT2: Here are some screenshots showing the problem: Resized Window to fit: Opened Start Menu - notice it cut off: Maximized window and then scrolled down - notice no Start Menu: I downgraded my graphic driver I downloaded from the Intel Download Center for the Graphic Media Accelerator 3150 (now: 8.14.10.1972) and now my "Generic non-PnP Montior" detects as "Digital Flat Panel (1024x768 60Hz)".

• 8007064c(2011) and 80280007(2009) persistant after all known repairs

  - by tiu44

  I'm on Windows 7 Home x64, and have ran into a major issue with Live Messenger(which I use daily). I have full offline installers for both 2011 and the last Wave 3 2009(14.0.8117.0416) Suites. Both give the following errors: Live Essentials 2011 Offline installer(official): An unknown error occured. Error:0x8007064c Source WLXSuite WL 2009 offline installer(official): You already have a more recent version of Windows Live. Error: OnCatalogResult:0x80280007 Next steps: If you want to install this older version, first uninstall any later versions that are on your computer. Get help with this error The 2011 installer also says it is updating messenger, I don't select anything else. Then last 2009 installer says their is a newer version that needs uninstalled even after the following procedures. MS Help pages provided all basically lead to using uninstall from control panel. Which I've uninstalled all Live components including watcom safety scanner and portable SQL from. I've followed online instructions for manually deleting folders from Program Files(x86), Appdata, and some others under \User\All Users and the one for the one account on the machine. I've used CCcleaner 3.01, ASC 3.7.3 and Beta 4 with deep scan along with deleting folders, and checked their uninstallers for Live components too, and none were there. wlmuninstaller.exe tool reports nothing, but after a failed install it finds something, but failes to clean it under all user admin privilege. The same errors still occur after all of that. Google searching I see people on forums suggesting reinstalling the OS cause MS doesn't even know how to fix this, but I'm hoping someone here can help. NOTE: I don't have System Restore or any other state freeze utilities going, and I don't have any real time AV going(I sometime scan with defender, anti rootkits, and online scanners). NOTE2:I posted this on windowslivehelp.com, before looking to see if the place was active or not, hoping I can get help here. Thanks

• USB 3.0 hard disk not detected on a particular host controller?

  - by Alvin Wong

  I have a USB 3.0 hard disk which has always been working on my desktop with an XHCI. Now I just bought a notebook with an XHCI (something with Intel's Ivy Bridge setup). The first time I plug the hard disk in its 3.0 port it is detected and working. A few hours later I try to connect it again, but seems that the notebook just ignored it! The light on the hard disk didn't blink as usual (instead it is hold at on). I then tested it with my desktop again and it is working perfectly. It gets trickier when I plug it in the USB 2.0 port of that notebook it is detected and working perfectly (despite the slower speed). Then I try to plug in an USB 2.0 USB flash drive to that USB 3.0 port, and it is detected (of course as USB 2.0). So, there are two USB 3.0 ports on my notebook's XHCI. Both of them are not working with my hard disk but working perfectly fine with my USB 2.0 UFD. What's wrong with it? When I plug in the hard disk, device manager doesn't change. I've tried re-installing the driver for the XHCI, but it changes nothing. Had I broke the USB 3.0-specific pins of both USB 3.0 ports?

• RDP or SSH connection trough Windows 2008 server VPN hang after a while

  - by xt4fs

  I have been experiencing a very strange issue with our VPN setup on Windows Server 2008. That server is running as a Xen Virtual Machine. We use it for two purposes, permit our mobile workers to connect to another server hosted somewhere else that only allow that ip, and use it to RDP or ssh to many other virtual machine on the same server. The server has no performance issue and still a load of memory free. All other virtual machine has no problem whatsoever. Many of those virtual machine have public IP (web servers) and all their firewall are set to allow only ssh connection or RDP connection from their local interface. When I am connecting directly with either ssh or RDP to one of the other virtual machine everything run without any issues. However, when I am doing so through the VPN after some time the connection just hang, it usually continue after some time (5 or 10 minutes). It seems as more there is network usage more often it happen to a point where it is completely unusable. The worst thing I can do to hang it faster is to actually ping the vpn client IP from the local network, after some time the latency increase until it hang. This happen even if I do RDP to the local ip of the VPN server trough the VPN. The server report no problem and if I disconnect to the vpn and reconnect right away everything is alright. There is nothing wrong in the VPN server log. I have taught at the beginning that it could have been an issue with the Host server so I try to RDP,ssh directly to the guest and I have experience no issue while doing this, so it really seems to be a problem with the VPN server on Windows server 2008. Another very weird thing is it does not seems to be of any issue if you only do Internet (NAT) without trying to connect to any local ips.

• can't connect to vsftpd from outside network

  i know this has been asked many times before, but nothing seems to resolve my issue. i have vsftpd running on ubuntu 10.04. i can connect with ftp localhost on the machine. i can connect from another machine in my network. i just cannot connect from outside. the machine is behind an airport extreme managed by airport utility on a mac. 21 is open as per nmap: macmini:~$ nmap localhost Starting Nmap 5.21 ( http://nmap.org ) at 2011-04-10 23:49 EDT Nmap scan report for localhost (127.0.0.1) Host is up (0.00045s latency).

• Windows 7 x64 RTM USB Port Has Power But Won't Recognize Mouse/Keyboard/Anything

  - by ben

  I have an odd error that doesn't seem to fit in with any of the other odd Windows 7 x64 USB errors that have been kicked up on Google. Here we go: Uninstalled Tortoise SVN and clicked restart computer. My machine had been up for around 28 days On reboot my mouse and keyboard failed to work anymore, couldn't log in. Tried every USB port I have on my Dell 390 and the ports on my Dell 19's, nothing worked. They had power but Windows would not respond when I manipulated the keyboard/mouse. Rebooted my computer and pressed F2 to get into bios, my keyboard is working fine in bios. Keyboard and mouse work fine on other computers when using USB. Found adapters for keyboard and mouse to convert from USB to PS/2 ports, works fine. I'm actually typing this question on the same keyboard, same computer, just using PS/2 ports for my mouse and keyboard. It appears to be a Windows 7 x64 issue. Other things I have tried: Multiple other mice and keyboards, iphone, all with no luck. Each one gets power, but Windows never tries to install drivers or sees that they are connected. Uninstall and reinstall all USB drivers. Drives uninstall and reinstall fine and report no errors in Control Panel. In Power Management I disallow Windows from turning off USB ports to save power Installed the latest nVidia drivers for my graphics card, no change. Anyplace else I can look/try? Thanks!

• How (in)secure are cell phones in reality?

  - by Aron Rotteveel

  I was recently re-reading an old Wired article about the Kaminsky DNS Vulnerability and the story behind it. In this article there was a quote that came across a little bit exaggerated to me: "The first thing I want to say to you," Vixie told Kaminsky, trying to contain the flood of feeling, "is never, ever repeat what you just told me over a cell phone." Vixie knew how easy it was to eavesdrop on a cell signal, and he had heard enough to know that he was facing a problem of global significance. If the information were intercepted by the wrong people, the wired world could be held ransom. Hackers could wreak havoc. Billions of dollars were at stake, and Vixie wasn't going to take any risks. When reading this I could not help but feel like it was a bit blown-up and theatrical. Now, I know absolutely nothing about cell phones and the security problems involved, but to my understanding, cell phone security has quite improved over the past few years. So my question is: how insecure are cell phones in reality? Are there any good articles that dig a bit deeper into this matter?

• Cisco ASA user authentication options - OpenID, public RSA sig, others?

  - by Ryan

  My organization has a Cisco ASA 5510 which I have made act as a firewall/gateway for one of our offices. Most resources a remote user would come looking for exist inside. I've implemented the usual deal - basic inside networks with outbound NAT, one primary outside interface with some secondary public IPs in the PAT pool for public-facing services, a couple site-to-site IPSec links to other branches, etc. - and I'm working now on VPN. I have the WebVPN (clientless SSL VPN) working and even traversing the site-to-site links. At the moment I'm leaving a legacy OpenVPN AS in place for thick client VPN. What I would like to do is standardize on an authentication method for all VPN then switch to the Cisco's IPSec thick VPN server. I'm trying to figure out what's really possible for authentication for these VPN users (thick client and clientless). My organization uses Google Apps and we already use dotnetopenauth to authenticate users for a couple internal services. I'd like to be able to do the same thing for thin and thick VPN. Alternatively a signature-based solution using RSA public keypairs (ssh-keygen type) would be useful to identify user@hardware. I'm trying to get away from legacy username/password auth especially if it's internal to the Cisco (just another password set to manage and for users to forget). I know I can map against an existing LDAP server but we have LDAP accounts created for only about 10% of the user base (mostly developers for Linux shell access). I guess what I'm looking for is a piece of middleware which appears to the Cisco as an LDAP server but will interface with the user's existing OpenID identity. Nothing I've seen in the Cisco suggests it can do this natively. But RSA public keys would be a runner-up, and much much better than standalone or even LDAP auth. What's really practical here?

• Windows XP only loads in VGA mode, and crashes when raising resolution

  - by Harel

  My kid's computer (Windows XP, SP3) started to (what appears to be) crash on boot. It will only boot in Safe or VGA mode, and if I try to raise the resolution from 640x480 it just reboots itself, and a error appears in the Event Log. When it loads up not in VGA mode, the monitor shuts off just after the windows logo is shown. It seems like windows is actually running but I can't see anything on screen (monitor is off for lack of signal). Nothing was installed recently that I know of, short of the usual windows updates. Thanks, Harel Below is the event log error: Event Type: Error Event Source: System Error Event Category: (102) Event ID: 1003 Date: 15/04/2012 Time: 16:27:11 User: N/A Computer: ----- Description: Error code 1000008e, parameter1 c0000005, parameter2 f745b0bf, parameter3 ede24f98, parameter4 00000000.

• Is there a way to avoid Wacom Control Panel to stop showing in certain cases?

  - by S.gfx

  This is the problem: Suddenly, you double click on desktop Wacom tablet settings icon, and it won't show the dialog. It appears to be loaded as it's shown down in the Windows taskbar. I suspect it is caused by change of resolution or some setting, maybe suddenly it sets the origin of the panel dialog at some 3000 pixels to the right or something. I have dug in the wacom_tablet.dat file to see if I can fix it changing some value there, but it looks like a log, a history, more than a ini for settings. And anyway does not solve it. My solution is having always a very complete settings file done and backed up to restore (with Wacom utility for this, which in previous driver versions did not exist) when this happens, but it is counter-productive: You change the settings even per each project (and software) needs. I have seen it happenning with Cintiq 12", intuos4 A6, Graphires, Intuos 1. Is it just me, doing something weird every time? I doubt it, it's normal use, I am amazed that it seems no one else has had this problem (or nobody asked). It happens often with typical use. Maybe it's because I'm setting a shortcut in the desktop? Weird as it works perfect until some random moment. (I have dug in Wacom's forums and FAQs, then here, but nothing related to it. Neither in "related questions".) The thing happens in Win XP, 7, etc. It's done so for years in my experience, and several times at work, which is worse.

• How to stop my VPS from picking up ARP reqs it is not supposed to?

  - by Charles Stewart

  Machine: Xen-3.0 image running stable Debian Linux 2.6.18, pretty vanilla. My VPS provider asks me to deal with some trouble my image is causing, namely handling IP addresses it is not supposed to: The problem is that your server seems to be configured to use IPs that have not been appointed to you. Your server responds to ARP requests for the IPs 81.171.111.219 and 81.171.111.218. But you are not allowed to use those. Not explicitly, as far as I can tell! At least, nothing under /etc or /var/tmp mentions these IP addresses. But arp -v says something I can't make sense of: Address HWtype HWaddress Flags Mask Iface 81.171.111.1 ether 00:0C:DB:E3:80:00 C eth0 Entries: 1 Skipped: 0 Found: 1 What is it listening to? The possibilities seem to be: It's not my fault: my VPS providers have overlooked something. What might that be? 81.171.111.1 means I'm happy listening in on ARP requests that I shouldn't be: how do I change this? In any case, what does this mean? I'm looking in completely the wrong place for information on what my image is doing. Where should I be looking?

• Why am I unable to reach local network computers, but able to browse the web?

  - by Igor Zinov'yev

  I have a weird problem. Today after turning my Ubuntu 9.10 PC on I can't connect to my local network, but I can use the Internet. We have a single Windows 2003 server machine that acts as a local main DNS server, DHCP server and a domain controller. Although it seems to give me the local IP address, I can not ping it, as well as any other machine on the net. I have tried all of the below and it didn't help: Rebooting; Reconnecting to the network; Forcing the dhclient to renew the IP address; Deleting and creating new connection profiles; Plugging my machine into another network outlet; Maybe it has something to do with routing, because I have tampered with routing tables the day before, but the tables seem ok to me: $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 vboxnet0 0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0 Our LAN uses a D-Link DI-604 router, and it looks to me as if I am connected to the network outside the router. I can not even access its administration page. Please at least suggest what I can do to solve this. P.S. What seems strangest to me is that I can access the PC in question from outside the network by opening a port on the router. I have managed to ssh to it from outside, but I still can't ping nothing on the inside. P.P.S Today I tried reinstalling network-manager with --purge option, but it did no good. After that I created a new DCHP reservation for my PC in order to change my local IP, but that didn't change anything either. My PC is able to get a DHCP offer, but then it's unable to connect to any local computers. I am desperate.

• postfix and iRedMail- Relaying Denied

  - by Lock

  I am trying to setup iRedMail and am way over my head here. I have installed it, and can send emails internally, but not externally. When I send an email from outside, I get the following return email: The error that the other server returned was: 550 550 5.7.1 <[email protected]>... Relaying denied (state 13). Now I have no idea where to start looking! Any ideas? I have really only just installed iRedMail so I am unsure what else I need to do to get it working. I've pointed my MX records to that server, so that shouldnt be the problem. Also- if i stop postfix (so nothing is listening on port 25) and send a test email, I get the same reply back. Why would I get the same reply back even if postfix is stopped? I have run tcpdump over 25 and can see the packets coming in/out, so its definitely a configuration issue! I suppose my question is not really "what is my problem", but more "What configuration needs to be completed on postfix and iRedMail?"

• Windows XP Boot Issue - Diagnosing A Hard Drive Failure

  - by duffymo

  My five-year-old HP desktop running Windows XP SP3 wouldn't boot from the hard drive yesterday afternoon. I would see the boot sequence begin, then nothing but a black screen. Fortunately, I had just done an Acronis backup to my external drive in the morning, and I have a bootable USB key. I put the USB key into the drive, powered up the machine, and put the USB key first in line in the boot sequence. Voila! My machine came alive. But now I'm confused as to what the problem is and what to do next. I assumed that my hard drive was toast. But now that the machine is alive I can see files on my C: drive that have changes I made just yesterday. Clearly the drive is not dead. Here are my questions: What could explain my inability to boot from the hard drive? What would a remedy be? What's my best course of action? Should I replace the hard drive with a new one? If I replace the hard drive, do I reinstall the OS and apply the backup I did yesterday? If I decide that re-installing Windows XP makes no sense, how do I get back the Acronis backup that I did yesterday? I don't want to lose that. UPDATE: I just learned one more key fact. I'm having some work done on my house. I neglected to shut my machine down before the contractor came. My wife said he shut down the power to do some work on a circuit and then powered the house back up. I have a surge protector, but is it possible that cycling the power did some damage?

• Configure IIS Web Site for alternate Port and receive Access Permission error

  - by Andrew J. Brehm

  When I configure IIS to run a Web site on Port 1414, I get the following error: --------------------------- Internet Information Services (IIS) Manager --------------------------- The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020) However, as according to netstat the port is not in use. Completely aside from IIS, I wrote a test program (just to open the port and test it): TcpListener tcpListener; tcpListener = new TcpListener(IPAddress.Any, port); try { tcpListener.Start(); Console.WriteLine("Press \"q\" key to quit."); ConsoleKeyInfo key; do { key = Console.ReadKey(); } while (key.KeyChar != 'q'); } catch (Exception ex) { Console.WriteLine(ex.Message); } tcpListener.Stop(); The result was an exception and the following ex.Message: An attempt was made to access a socket in a way forbidden by its access permissions The port was available but its "access permissions" are not allowing me access. This remains after several restarts. The port is not reserved or in use as far as I know and while IIS says it is in use, netstat and my test program say it is not and my test program receives the error that I am not allowed to access the port. The test program ran elevated. The IIS Site is running MQSeries, but the MQ listener also cannot start on port 1414 because of this issue. A quick search of my registry found nothing interesting for port 1414. What are socket access permissions and how can I correct mine to allow access?

• PC shut downs automatically after 10-20 second. No POST screen, no beeps

  - by emzero

  I have this not-so-old computer that's not being used for a year or so. Specs: Motherboard: ASUS PN5-E SLI CPU: Intel Core2Duo E4300 RAM:2x2GB SuperTalent DDR2-800 VGA: Zogis GeForce 7950GT PSU: Vitsuba San-55-S 550w HD: No hardrives yet When I power on the computer, everything seem to start, but right away the whole system shuts down. I've removed and changed the RAM sticks, take out the VGA, everything I could think of. So what could it be causing this? The PSU? The motherboard is dead? The CPU? Any help to isolate the problem will be useful. Thanks PS: Please don't close the question, this could be helpful to anybody having a similar problem, even with different hardware. UPDATE I've removed the old thermal paste and apply a brand new one. I also cleaned every dust using a high pressure gas dust remover. Checked for bad capacitors, all of them seem ok. Opened the PSU, removed big giant dust balls, cleaned with high pressure dust remover. Still the same problem, but now it stays powered on for almost 20 seconds maybe. But no POST screen, no beeps at all, nothing. So I suspect it's a motherboard or PSU failure. Unfortunately I don't have an energy tester to test the PSU... Don't know what else to try. I don't have another 775-motherboard to test the CPU, RAM and VGA with it.

• No sound through headset - only mic is working

  - by Kristis

  I noticed that no sound is being played to my headphones. The laptop has a conexant sound card together with the sounds apps provided. But the thing is that I also noticed that now instead of one playback device - 2 are presented: speakers and headphones. And while speakers do play sound nicely - even test sound are not played through headphone output. Also, headphone output does not have a jack assigned to it, while speakers have L R Rear panel Analog Jack(my laptop does not have a jack on the back - only on the right). Also - my headphones have a mic as well - and when I plug it in - the mic is working(using top panel digital jack),but the headphones themselves are not. And laptop is recognizing when audio device is plugged in. And I checked the headset on other devices - the headphones are working. I have tried updating drivers, rolling back drivers and completely uninstalling drivers and then restarting - nothing helped. I imagine that I somehow need to reconfigure the jack configuration just have no idea how and where. Any suggestions? Thanks

• PC won't PXE boot to WDS/MDT with Dell Optiplex 755

  - by Moman10

  I am trying to set up a basic MDT solution. I have set one up in the past at a previous job and it worked flawlessly, however here I'm running into a problem and am having no luck getting around it. I've installed Windows Server 2012 and MDT 2013, along with adding on the WDS role. I haven't configured much outside of the defaults for WDS, basically just set PXE response to respond to all clients (and unchecked admin approval). This machine does not run a DHCP server. I looked on the DHCP scope of our DHCP server, it shows options 66/67 checked and the server name of the WDS server is in there as well. I didn't add this but I assume it was put on during the install process (I believe I had to manually make some adjustments at my old job for this). The PC I have is a Dell Optiplex 755. I have enabled the onbard NIC w/PXE boot option in BIOS and attempted to boot. I get a "TFTP...." error but nothing offering out a DHCP address like I'm used to. In my previous job it pretty much worked right out of the box. I've verified that PortFast is enabled on the port and I've tried a couple different PCs (but both are the same model, only model I have to work with). No matter what, I get the same error. The subnet the PC is in is a different subnet than where the WDS server is sitting, but there are IP helper statements on the switch and the PCs can get regular DHCP addresses just fine from the DHCP server, just doesn't seem to get offered out a PXE boot option. I don't know if the problem is a configuration with the server or the PC itself...but after a few days of Googling I'm running out of ideas. Does anyone have a good idea of something it may be?

• computer build for extreme tabbed browsing

  - by David Berger

  I'm interested in building or buying a task-specific computer for my brother. His requirements are ridiculously simple: the machine has to be able to wait in hundreds of web-based virtual waiting rooms at once and not crash. To be competitive, he needs to be able to enter the waiting rooms an dauto-refresh them faster. My question is, what priority do I give the different specs? My initial surmise is this: Connection speed (nothing to do with my build, but I kind of think this will be more beneficial than anything I build for him) Memory size -- I don't usually see firefox taking up more than a gig, even when heavily tabbed, but I think one gig for the operating system and two gigs for the browser are necessary. Processor speed -- I think the processor will affect performance, but even something out of date will do what he needs Memory speed/RAM bus -- I doubt this will matter much, but it seems just on this side of irrelevant. Everything else is a non-issue for him. Does this seem to stack up correctly? Also, since he's looking to stay on the cheaper side, and I might end up recommending a refurb to him, is there anything particularly egregious that Vista would do if it came pre-installed? If I build it myself, I'll give him linux, but if I have it shipped to him, I'm not sure I could walk him through the install process for linux, but I probably could walk him through the process to upgrade to Windows 7, if it were somehow worth it.

• TV won't go into standby

  - by Robert

  When I select Start-Turn off computer-Standby the 'turn off computer' option window closes, and then nothing else happens. I can start new applications, and Windows acts like I never selected standby. I ran it for several hours after that. If I have a TV program scheduled to record when I select standby I get a window (the Pinnacle TV software) asking if I'm sure, there are programs scheduled to record - and the computer just keeps running after I select yes, never going into standby. I added that detail as it shows the standby process is starting. [This problem also happens if a TV program is not scheduled, so the scheduler task in not running/in memory. This problem happens regardless of whether I'm not watching TV. This problem happens regardless of whether Media Center is running (it usually isn't, I'm using Pinnacle to watch TV).] I looked at "How to troubleshoot hibernation and standby issues in Windows XP" http://support.microsoft.com/kb/907477 - ACPI is enabled, and "standby" is an option in "Power Options Properties." So it appears to be setup correctly. Windows XP SP3 Media Center Edition, all current updates installed.

• X.org - mouse gets stuck on press

  - by grawity

  I'm using Arch Linux. Very often, when I click on something, the OS thing sees the mouse press but not the release. If it was a link or file I clicked, moving the cursor would drag it too. Hammering the same mouse button again gives no effect. Usually, if I tap the touchpad (ALPS), the system finally sees both press and release of that, and I can continue working. (This might be because it uses a different driver - synaptics instead of evdev.) As you can imagine, this is quite annoying even for someone who spends 70% of his life in front of a terminal app. This is not a mouse issue - I'm on a laptop, and this affects both the Trackpoint thing and an external USB mouse. This is not a DE or window manager issue - I have used GNOME (with Metacity, Compiz and Xfwm4), Xfce (with Metacity and Xfwm4), mwm, twm, awesome, and wmii. Doesn't seem to be a hardware thing - after rebooting into Windows XP, everything works fine. hal is used for the auto-configuration of devices (as I have to disconnect the USB mouse often), so Xorg.conf really has nothing of relevance. Xorg -version shows: X.Org X Server 1.6.3.901 (1.6.4 RC 1) Release Date: 2009-8-25 X Protocol Version 11, Revision 0 If it changes anything, the laptop is stone-age Dell Latitude C840. I kinda suspect either hal or the evdev thing to cause it, but I really have no ideas on what to check further. In other words, HALP!#$ This thing is driving me nuts.

• Debian - starting UFW (Uncomplicated Firewall) before network interfaces are operational

  - by Tomasz Zielinski

  I want to install UFW on Debian Lenny. Everything looks straightforward except that I don't know where to plug UFW startup script so that it configures iptables before hax0rs can break in. I've reviewed runlevel directories and in /etc/rc0.d, /etc/rc6.d and /etc/rcS.d there are items like these: S35networking -> ../init.d/networking S36ifupdown -> ../init.d/ifupdown Runlevel 0 and 6 are for shutdown and reboot so I guess nothing should be changed there, but runlevel S advertises itself (in README) like something for me: The scripts in this directory whose names begin with an 'S' are executed once when booting the system, even when booting directly into single user mode. The following sequence points are defined at this time: * After the S40 scripts have executed, all local file systems are mounted and networking is available. All device drivers have been initialized. (What bothers me is that both rc0/6.d and rcS.d point to the same networking and ifupdown scripts, but after looking at sources I believe those scripts are smart enough to figure out where to start and where to stop networking.) Now, I think that I should plug my /lib/ufw/ufw-init into /etc/rcS.d, with priority higher that the one of ifupdown and networking, i.e. <= 38 for my /etc/rcS.d. Am I right in this "analysis" ?
