• Why do fonts sometimes look "fat" on Mac OS X?

  - by jtimberman

  Sometimes when resuming from suspend, the fonts in Mac OS X look "fatter" than normal. Unfortunately right now I can't get my Macbook Pro to exhibit the "normal" behavior for comparison, it has been abnormal yesterday and today. If I can get screenshots of what I think is 'normal', I'll add them. "Fixing" this has been random. I use an external monitor, and sometimes unplugging it and plugging back in, or even turning it off and back on has worked. Sometimes with the display attached (or not) detecting displays works. Sometimes logging out or rebooting entirely is what it takes. Displays used: Macbook Pro 15" built-in display Dell 27" LCD (2009 model) Software where I see this happen, at least most noticably: Firefox (screenshots below) iTerm Things MacIrssi (screenshots below) I am using Mac OS X 10.5.8. "Abnormal" view from MacIrssi with Inconsolata 16 pt. image full size "Abnormal" view from Firefox. Finally got it to switch back, though after resuming from suspend its back to "fat" :-(. image full size And 'normal' in Firefox:

• setup lowcost image storage server with 24x SSD array to get high IOPS?

  - by Nenad

  I want to build let's name it a lowcost Ra*san which would host for our social site the images (many millions) we have 5 sizes of every photo with 3 KB, 7 KB, 15 KB, 25 KB and 80 KB per Image. My idea is to build a Server with 24x consumer 240 GB SSD's in Raid 6 which will give me some 5 TB Disk space for the photo storage. To have HA I can add a 2nd one and use drdb. I'm looking to get above 150'000 IOPS (4K Random reads). As we mostly have read access only and rarely delete photos i think to go with consumer MLC SSD. I read many endurance reviews and don't see there a problem as long we don't rewrite the cells. What you think about my idea? - I'm not sure between Raid 6 or Raid 10 (more IOPS, cost SSD). - Is ext4 OK for the filesystem - Would you use 1 or 2 Raid controller, with Extender Backplane If anyone has realized something similar i would be happy to get Real World numbers. UPDATE I have buy 12 (plus some spare) OCZ Talos 480GB SAS SSD Drive's they will be placed in a 12-bay DAS and attached to a PERC H800 (1GB NV Cache, manufactured by LSI with fastpath) Controller, I plan to setup Raid 50 with ext4. If someone is wondering about some benchmarks let me know what you would like to see.

• picking a linux compatable motherboard

  - by Chris

  Last time I bought a new computer (I build them myself) I got a motherboard that had really poor linux support for a long time. Specifically the audio. I had to wait months before the kernel supported the on board audio chipset. That is exactly the situation I'm trying to avoid this time around. I have some specific questions about "server motherboards" actually. I looked at a few models of server motherboards by intel, and some random models on newegg. I wasn't able to see much of a difference from regular desktop motherboard other than most had two sockets, and support for much more ram. These boards seem more popular with Linux users. Why? AMD and Intel both have server CPUs as well. Some question, what's the difference? To make this question more concrete, I was looking at this this motherboard. The main questions about it that I can't answer are: Can I get a motherboard without on board raid and audio? I wanted to get a hardware raid controller and a PCI audio card. I thought a server motherboard would be cheaper and not have these "extras", since who wants an audio card on a server? Where can I found out about Linux support for the components on this board? "Intel ICH10R", "Realtek ALC889", "Marvell 88E8056" I'm buying this computer to work as a Linux desktop for a lot of compiling, coding and audio/video work, but I don't want to rule out the possibility of installing windows and playing some games at one point. (even if the last game I got has been sitting in its box unopened for almost a year). Is it a good idea to buy a "server motherboard" and play games on it, or are desktop boards better value for this? The ultimate solution for me would be a motherboard that had GPL divers for onboard LAN, a single CPU socket, lots of PCI express and PCI. USB 3.0, and no fancy hard disk controllers since I'll be getting a separate one.

• Windows 7 BSOD when I walk away from the computer

  - by bobobobo

  I have a really weird experience with this new AM3 box I set up. Everything seems fine at first. But now I get frequent (daily) BSOD's, mostly when I walk away from the computer for more than 5 minutes (when the computer is idle). The BSOD's as shown by BlueScreenView almost always have to do with ntoskrnl.exe, and they'll do with really normal sounding operations, like SYSTEM_SERVICE_EXCEPTION, NTFS_FILE_SYSTEM, DRIVER_IRQL_NOT_LESS_OR_EQUAL, KMODE_EXCEPTION_NOT_HANDLED, BAD_POOL_HEADER - You name it. These are basically them, and they repeat after that, just random order. Its not like one is more consistently the problem than the other. I have Windows update ON and I let it do its updates everytime it wants to. I turned windows indexing service off, but it seems Windows 7 does a lot of background processing when I'm away - I'll come into the room and the fan will be going nuts (I'm pretty sure this isn't because the computer flies into a panic whenever I leave). I tried finding updates for my ASUS, and really there isn't much to install (except some new driver firmware). I'm going to install that to see if it helps, but what else could it be? Is it possible its a hardware issue with the board? Or is every Windows 7 user experiencing daily BSOD these days that I don't know about?

• Internet Troubles - PPPoE vs PPPoA?

  - by AkkA

  I have been having some internet troubles at home (ADSL2+ connection in Australia). We get random drop-outs from the authentication connection. It will keep the connection to the DSL service, but we lose authentication and either have to restart the router/modem (its combined, a Belkin one, not sure on model number) or unplug the phone cable, wait about 30 seconds and plug it in again. I've called the ISP (Telstra) a few times, but they only offer limited support when we dont use their supported hardware. Apparently something had happened on their side, they checked the box again (at least it sounded that simple), and told me it would be fine. It wasnt. I've replaced all the filters around the house, but that didnt help either. We do live a little bit away from the exchange (get a sync speed of about 3000/900), so I thought it could be due to line noise but that hasnt helped. Telstra allow both PPPoE and PPPoA connections (which I'm configuring through my router, dont have software on the PC side). I've been running PPPoA the whole time, would it make any difference changing it to PPPoE? If not, are there any other theories as to why we would be experiencing these drop-outs? It has been fine for at least 12 months, then suddenly started about 2 months ago.

• MicroSD card getting corrupted for no good reason

  - by ChaosR

  I recently bought an MicroSD card online. It's a Sandisk 16GB class 2. However, it has a nasty problem. Every time I fill it with my data, the fat tables get corrupted. I've tried reformatting it, blanking it, doesn't seem to solve the problem. I have tried windows and linux (ubuntu), both have the problem. I've used my usb microsd readers, and even tried putting it in my phone and putting data on it from there. All have this problem. Now the really odd thing is, besides the corrupted file tables, no programs can find anything wrong with the hardware. I've tried both chkdisk and "badblocks -w", neither give any type of error. Now I don't know if the actual data gets corrupted, or if its just filesystem tables. What happens is that one or more folders start showing a load of chinese-charred (random UTF8 symbols I suppose) folders and files, and it is impossible to do anything with those. All the other data (outside of the corrupted folders) seems fine. I've tried to test it, and the problem doesn't seem to show up until I fill the disk upto about 3~4GB. After that I can still access the data. But as soon as I eject/safely remove/unmount it, the bad things happen somehow. Next time I plug it in, the folders I most recently wrote to (but sometimes also the folders I wrote the time before last time to) are all gibberish. Does anybody have any clue what might be going on here? EDIT: It seems I can't even put ext3 or ext4 on it, they both complain about a corrupted journal. Gheh, guess something is really broken here.

• What does "incoming" and "outgoing" traffic mean?

  - by mgibsonbr

  I've seen many resources explaining how to set up a server's firewall to allow incoming and outgoing traffic on HTTP standard ports (80 and 443), but I can't figure out why I would need either of them. Do I need to unblock both for a "regular" web site to work? For file uploads to work? Are there situations where it would be advisable to unblock one and leave the other blocked? Sorry if that's a basic question, but I couldn't find it explained anywhere (also I'm not a native english speaker). I know in a "regular" web site the client is always the one who initiates a request, so I'm assuming a web server must accept incoming traffic on those ports, and my common sense tells me the server is allowed to send a response without unblocking anything else (otherwise it wouldn't make sense to have two types of rules). Is that correct? But what is an outgoing web (service) traffic, and what would be its use? AFAIK if the server wanted to initiate a connection with another machine, the specific port that matters is the one in the other end (i.e. the destination port would be 80), on its end any free port could be used (the source port would be random). I can open HTTP requests from my server (using wget for instance) without unblocking anything. So I'm assuming my concepts of "incoming" and "outgoing" are wrong somehow.

• Desktop PC does not power up on power button

  - by hIpPy

  When I press the power button on my desktop, it does not power up completely. Before I press the power button, I see lights on the motherboard. Everything is normal. On power button press, the fans on the cpu, graphics card and motherboard start to spin a little for a second or two and then they stop. No beeps during this process. It has been doing this for a while now but it used to start up after some trials. Once it starts up, I have NO issues at all like random shutdowns so it is not an issue with OS. Update: I left the desktop off for a few days and it started. I'm just guessing here but it seems as if the PSU (Antec TP2-550ATX) is dying out and does not have enough power now - just a guess. It's an old desktop assembled in 2005 but I have maintained it well. Update: I always keep the desktop running and I never shut it down. During updates or manual restarts, it powers up without issues. I wonder if this sheds lights on the issue. Any idea how I can narrow down the issue? ex: if I can find if the PSU is dying etc. I'd really like to fix the issue. Please help. Thanks. Below is the complete configuration.

• Dell PS/2 Keyboard Stops Working Randomly After Power Disturbance

  - by Kenneth Murphy

  I have a Dell PS/2 keyboard connected to a desktop PC running Slackware 12.2 & Windows XP. After a recent, brief power outage/disturbance at my home, the keyboard has begun to quit working at random times. It has stopped at POST, but not by keyboard error -- I have to press the F1 key to continue booting, and at times the keyboard has already stopped working. Other times, the keyboard will work perfectly for a long time (a day or more) before it finally quits. It has stopped at boot, in Windows XP, and in Slackware. The led lights continue to work regardless. I have tried another PS/2 keyboard and it seems to be immune to this problem. The USB mouse always works. Does anyone have any ideas about how this might have happened? If this is related to the power disturbance that killed the power to the running PC, is it feasible that it would have only fried the keyboard itself (which still works sometimes) and not the PS/2 port nor anything else? I have experienced no other problems since the event.

• Samsung laptop randomly shuts down

  - by Dmatig

  I've rewritten this question because it turned into an indecipherable mess. I have a Samsung R560 laptop that is overheating, and shutting itself down under load consistantly. Thank you quickcel for reccomending me Speedfan to monitor my temps. Here they are (Load / Idle): (Ignore "Temp1 and Temp2", whatever sensors they are they'd always random, pretty sure they're broke). The load temperature is after just 5 minites of playing Fallout 3 - another 5 minutes and it (the GPU - 9600M GS) consistantly breaches the mid 90's then shuts down, so it's hard to get a good picture of it. I'm looking for some solution or way to decrease these temperatures, because they seem far too high even idle. I've tried: Opening up the case and clearing of all dust with compressed air. Updating drivers for my Graphics card Have purchased and am using a notebook cooler I don't want to: Undervolt / underclock (defeats the point of having a more expensive card) Use lower power / performance settings (again, i might as well have bought something cheaper) Is there anything else i can try (software or inexpensive hardware) that can help me fix this? Has anybody had a Samsung laptop and knows if this can be sorted under my warranty, and the turnaround time of sending it off (UK?)(it has always ran hotter than it should, but now at 6 months old is getting hot enough to power off)

• To what extent is size a factor in SSD performance?

  - by artif

  To what extent is the size of an SSD a factor in its performance? In my mind, correct me if I'm wrong, a bigger SSD should be, everything else being equal, faster than a smaller one. A bigger SSD would have more erase blocks and thus more leeway for the FTL (flash translation layer) to do garbage collection optimization. Also there would be more time before TRIM became necessary. I see on Wikipedia that it remarks that "The performance of the SSD can scale with the number of parallel NAND flash chips used in the device" so it seems throughput also increases significantly. Also many SSDs contain internal caches of some sort and presumably those caches are larger for correspondingly large SSDs. But supposing this effect exists, I would like a quantitative analysis. Does throughput increase linearly? How much is garbage collection impacted, if at all? Does latency stay the same? And so on. Would the performance of a 8 GB SSD be significantly different from, for example, an 80 GB SSD assuming both used high quality chips, controllers, etc? Are there any resources (webpages, research papers, presentations, books, etc) that discuss correlations between SSD performance (4 KB random write speed, latency, maximum sequential throughput, etc) and size? I realize this does not really sound like a programming question but it is relevant for what I'm working on (using flash for caching hard drive data) which does involve programming. If there is a better place to ask this question, eg a more hardware oriented site, what would that be? Something like the equivalent of stack overflow (or perhaps a forum) for in-depth questions on hardware interfaces, internals, etc would be appreciated.

• Cisco IOS BVI ACL: Only allow established UDP

  - by George Bailey

  Related: Cisco IOS ACL: Don't permit incoming connections just because they are from port 80 I know we can use the established keyword for TCP.. but what can we do for UDP (short of replacing a Bridge or BVI with a NAT)? Answer I found out what "UDP has no connection" means. DNS uses UDP for example.. named (DNS server) is lisenting on port 53 nslookup (DNS client) starts listening on some random port and sends a packet to port 53 of the server and notes the source port in that packet. nslookup will retry 3 times if necessary. Also the packets are so small that it does not have to worry about them coming in the wrong order. If nslookup receives a response on that port that comes from the servers IP and port then it stops listening. If the server tried to send two responses (for example a response and a response to the retry) then the server would not care if either of them made it because the client has the job to retry. In fact.. unless ICMP 3/3 packet gets through the server would not know about a failure. This is different from TCP where you get connection closed or timed out errors. DNS allows for an easy retry from the client as well as small packets.. so UDP is an excellent choice because it is more efficient. In UDP you would see nslookup sends request named sends answer In TCP you would see nslookup's machine sends SYN named's machine sends SYN-ACK nslookup's machine sends ACK and the request named's machine sends the response That is much more than is necessary for a tiny DNS packet

• Netgear router keeps disconnecting iPhone

  - by DisgruntledGoat

  My old router (Voyager 2091) packed up so I just got a new router - a Netgear N150 model DGN1000. My laptop connects OK wirelessly, but my iPhone 4S is constantly getting "disconnected" - it has perfect wifi signal and is seemingly connected to the router, but no pages load (it says "server cannot be found"). If I disconnect manually ("forget this network") then reconnect, it works fine again for a random amount of time (usually 10-30 minutes) then I get the same problem again. I've done some searching and this appears to be a known problem - there are dozens of forum posts out there lamenting similar connection problems. The only advice I have seen is to set a specific channel under Wireless Settings on the router CP, although every forum post recommends a different channel! 1, 3, 5, 6, 11... I have tried them all for hours at a time and get the exact same problem. The firmware is up to date. Is there an actual solution for this, or do I need to get a different router just to be able to use my iPhone?

• Applications randomly alt-tab? (especially full screen games)

  - by Henry Scotts

  I'm not sure when this began, how it happens, or why it happens, but it is quite bothersome and apparently random. Just randomly throughout the day my computer will just go to the desktop. I could be in a full screen game and it will just immediately alt tab and present the desktop. Or I could be watching a movie and this happens. Sometimes it happens once every three hours and other times (just today actually) it did it twice in the span of 30 seconds. I am positive I am not pressing a hotkey because I launched a game, sat idle, and noticed it alt tab while cleaning up around my room after about 20 minutes. Sometimes it goes days without this happening. Specs: Windows 7 Ultimate 64 Bit, 10 gigs of RAM, GeForce GTX 260, Intel Xeon CPU. I also have basically nothing running when it happens other than the game and FireFox. My FireFox add-ons: Adblock Plus, Download Statusbar, Firebug, FirePHP, lazarus form recovery, tree-style-tabs, yslow. I doubt FireFox is causing the issue but I figured I'd include it anyway because it is the only application I have running when it happens. As for user processes I have running: VCDDaemon (context menu for virtual clone drive), razerhid (mouse), OSD, taskhost, dmw (desktop window manager), anyfullscreengame, audiorepeater, netsession_win, explorer, razerofa, tsvncache, firefox, plugin-container, and EKIJ5000MUI (printer). Whew. Okay. That was a lot of information. If someone could diagnose this I would be most grateful for this has been around with me for years.. Thanks for reading! PS: I doubt it's a virus because I never download illegal software and pretty much only browse Reddit and Stackexchange and play games. If it was a virus it would be a pretty lame one.. Hah..

• Hard Disk Not Counting Reallocated Sectors

  - by MetaNova

  I have a drive that is reporting that the current pending sectors is "45". I have used badblocks to identify the sectors and I have been trying to write zeros to them with dd. From what I understand, when I attempt writing data directly to the bad sectors, it should trigger a reallocation, reducing current pending sectors by one and increasing the reallocated sector count. However, on this disk both Reallocated_Sector_Ct and Reallocated_Event_Count raw values are 0, and dd fails with I/O errors when I attempt to write zeros to the bad sectors. dd works fine, however, when I write to a good sector. # dd if=/dev/zero of=/dev/sdb bs=512 count=1 seek=217152 dd: error writing ‘/dev/sdb’: Input/output error Does this mean that my drive, in some way, has no spare sectors to be used for reallocation? Is my drive just in general a terrible person? (The drive isn't actually mine, I'm helping a friend out. They might have just gotten a cheap drive or something.) In case it is relevant, here is the output of smartctl -i : Model Family: Western Digital Caviar Green (AF) Device Model: WDC WD15EARS-00Z5B1 Serial Number: WD-WMAVU3027748 LU WWN Device Id: 5 0014ee 25998d213 Firmware Version: 80.00A80 User Capacity: 1,500,301,910,016 bytes [1.50 TB] Sector Size: 512 bytes logical/physical Device is: In smartctl database [for details use: -P show] ATA Version is: ATA8-ACS (minor revision not indicated) SATA Version is: SATA 2.6, 3.0 Gb/s Local Time is: Fri Oct 18 17:47:29 2013 CDT SMART support is: Available - device has SMART capability. SMART support is: Enabled UPDATE: I have run shred on the disk, which has caused Current_Pending_Sector to go to zero. However, Reallocated_Sector_Ct and Reallocated_Event_Count are still zero, and dd is now able to write data to the sectors it was previously unable to. This leads me with several other questions: Why aren't the reallocations being recored by the disk? I'm assuming the reallocation took place as I can now write data directly to the sector and couldn't before. Why did shred cause reallocation and not dd? Does the fact that shred writes random data instead of just zeros make a difference?

• Nginx proxy to IIS Connection Timeout

  - by MitMaro

  I am having an issue with random timeouts with a Nginx proxy connecting to an IIS machine. I have been watching a packet capture between the two servers and it seems that the IIS machine is receiving a SYN packet but is not responding with what I think should be an ACK response. Before the timeout occurs there seems to be a slower response from the IIS server. There is no unusual memory or processor usage on the IIS or Nginx machine. Some information on the servers and setup: Nginx Machine: Ubuntu 10.04 64bit Nginx 0.7.65 Amazon EC2 Windows Machine: Windows Server 2008 IIS 7 ASP.net Application in Integrated Mode Nginx Error: 2011/01/10 17:57:40 [error] 8297#0: *30 connect() failed (110: Connection timed out) while connecting to upstream, client: 209.***.***.***, server: secure.example.com, request: "GET /a/path/deliver.aspx HTTP/1.1", upstream: "http://***.***.***.****:****//another/path/deliver.aspx", host: "secure.example.com" WireShark Packets 6521.449528 10.***.***.*** -> 174.***.***.*** TCP 38695 > us-cli [SYN] Seq=0 Win=5840 Len=0 MSS=1460 TSV=477422103 TSER=0 WS=7 6524.443239 10.***.***.*** -> 174.***.***.*** TCP 38695 > us-cli [SYN] Seq=0 Win=5840 Len=0 MSS=1460 TSV=477422403 TSER=0 WS=7 6530.443241 10.***.***.*** -> 174.***.***.*** TCP 38695 > us-cli [SYN] Seq=0 Win=5840 Len=0 MSS=1460 TSV=477423003 TSER=0 WS=7

• How I can fix the "Display Driver has stopped responding and has recovered"?

  - by Vitor Rangel

  I'm using a GeForce GTX 580, with Windows 7 64-bit. The driver version of the GTX is 301.42. The problem happens after a few minutes, when I'm playing specifc games. It won't happen in all games - And I don't have any idea why these games doesn't work. The games that doesn't work: Battlefield 3, Civilization V, Sniper Elite V2. The games that work: Mass Effect 3, Crysis 2, Team Fortress 2, Left 4 Dead 2, Skyrim, L.A. Noire. As you can see, it's not a problem of "The games that demand more stop working". I've tryed updating the driver of the graphics-card, the bios of the motherboard, even formated my computer (It was needing it) and instaled every driver in the last version possible. This problem happens since I bought my graphics-card, 6 months ago. After a few minutes, from 10 to 20, the pixels in the monitor become strange, with random colors and effects, like it was broken. Then, everything goes black, and the message appears "Display Driver has stopped responding and has recovered". After that, I need to close the game and start again. I am not overclocking, and my temperature never goes higher than 70ºC.

• Drupal 7: One-time user account

  - by Noob

  I'm going to create a survey in Drupal 7 with the webform module, installed on a debian system which may be adapted in every way. The users (personally known, approx. 120) doing that survey will walk into a room and complete the survey in browsers on different computers. After that, they'll leave the room and other persons will enter, complete the survey on the same computers and so on. Each user may enter only one submission. The process needs to be anonymous, i. e. I mustn't have any idea of who did wich submission. My current solution is to generate random one-time-passwords and hand out one password per user (without noting who got which password). Within the survey there will be a password field where the one-time-password is entered. The value is checked by webform to be unique. I'll get the data via csv or Excel and verify the passwords manually in excel by comparing them to the list of valid passwords. The problem is: I don't like the idea of manually generating the password list, copying it to excel and doing a manual check. That's a good idea for one-time-use, but we're going to repeat the survey every once in a while. I'd rather generate one-time-logins (like user0001/fdlkjewf, user0002/dfrefnnr, ...) for each survey, hand them out to the users and let drupal/debian/whatever check whether a submission is valid or not. Do you have any idea how to batch-generate about 120 users with one-time-passwords in Drupal 7 and verify that each user may submit the form only once? Do you even have a better idea how to accomplish the task within the intranet? Thank you for your help.

• How browsers handle multiple IPs

  - by Sandman4

  Can someone direct me to information on exact browsers behavior when browser gets multiple A records for a given hostname (say ip1 and ip2), and one of them is not accessible. I interested in EXACT details, like (but not limited to): Will browser get 2 IPs from OS, or it will get only one ? Which ip will browser try first (random or always the first one) ? Now, let's say browser started with the failed ip1 For how long will browser try ip1 ? If user hits "stop" while it waits for ip1, and then clicks refresh which IP will browser try ? What will happen when it times-out - will it start trying ip2 or give error ? (And if error, which ip will browser try when user clicks refresh). When user clicks refresh, will any browser attempt new DNS lookup ? Now let's assume browser tried working ip2 first. For the next page request, will browser still use ip2, or it may randomly switch ips ? For how long browsers keep IPs in their cache ? When browsers sends a new DNS request, and get SAME ips, will it CONTINUE to use the same known-to-be-working IP, or the process starts from scratch and it may try any of the two ? Of course it all may be browser dependent, and may also vary between versions and platforms, I'd be happy to have maximum of details. The purpose of this - I'm trying to understand what exactly users will experience when round-robin DNS based used and one of the hosts fails. Please, I'm NOT asking about how bad DNS load balancing is, and please refrain from answering "don't do it", "it's a bad idea", "you need heartbeat/proxy/BGP/whatever" and so on.

• Docking Station Sound Doesn't Work on Dell D830 with Windows 7

  - by cisellis

  I have a Dell Latitude D830 laptop that is running Windows 7 Enterprise x64. I connect to a docking station during the day with multiple monitors, a keyboard and a mouse. Everything runs with no problems including most of the docking station ports (usb, monitors, etc.) However, the sound port from the docking station does not work since the upgrade to Windows-7. Even with the laptop plugged in, the sound always comes out of the laptop, not the headphones plugged into the docking station. Here's what I've tried: I've seen other issues like via Google this that seem to be mostly unanswered. I found one or two that referenced using the Vista x64 drivers, especially the Nvidia drivers. I do not have an Nvidia chipset but I've reinstalled the sound drivers and that has not helped. I don't have a support contract and considering the cost is usually high to call Dell, that's not an option. Dell's forums are pretty much a wasteland and I've found no help there. Since this is a docking station I thought I might need to try the SATA or Intel chipset drivers from the dell site instead, however I'm not really sure and I need to work on this laptop in the meantime. I can't really afford the downtime to experiment with random drivers all day in case they turn out to be incompatible (Dell still hasn't added Windows 7 to their support site as far as I can tell). Does anyone have any other ideas? Has anyone had this issue and solved it? If so, how? Thanks in advance for your help.

• Router reporting failed admin login attempts from home server

  - by jeffora

  I recently noticed in the logs of my home router that it relatively regularly lists the following entry: [admin login failure] from source 192.168.0.160, Monday, June 20,2011 18:13:25 192.168.0.160 is the internal address of my home server, running Windows Home Server 2011. Is there anyway I can find out what specifically is trying to login to the router? Or is there some explanation for this behaviour? (not sure if this belongs here or on superuser...) [Update] I've run both Wireshark and netmon for a while on my home server. Wireshark captured the traffic, but didn't really show anything useful (or nothing I could make use of). A simple HTTP GET request is sent from the server (192.168.0.160) to the router (192.168.0.1), from a seemingly random port (I've seen examples from 50068, 52883), and it appears to do it twice in quick succession (incrementing port by 1), about every hour. Running netstat around the time of the failure didn't show anything (probably too long after anyway). I tried using netmon as it categorises by process, so I thought it might show a corresponding process for the port. Unfortunately, this comes in under the 'unknown' category, meaning it's basically just a slower, less useful Wireshark. I know there's not much to go on here, but does this help in anyway?

• Docking Station Sound Doesn't Work on Dell D830 with Windows 7

  - by cisellis

  EDIT: I can only mark one answer as the correct one but the actual solution was a combination of two comments (updating the BIOS to A15 AND installing the Sigmatel audio drivers). I have a Dell Latitude D830 laptop that is running Windows 7 Enterprise x64. I connect to a docking station during the day with multiple monitors, a keyboard and a mouse. Everything runs with no problems including most of the docking station ports (usb, monitors, etc.) However, the sound port from the docking station does not work since the upgrade to Windows-7. Even with the laptop plugged in, the sound always comes out of the laptop, not the headphones plugged into the docking station. Here's what I've tried: I've seen other issues like via Google this that seem to be mostly unanswered. I found one or two that referenced using the Vista x64 drivers, especially the Nvidia drivers. I do not have an Nvidia chipset but I've reinstalled the sound drivers and that has not helped. I don't have a support contract and considering the cost is usually high to call Dell, that's not an option. Dell's forums are pretty much a wasteland and I've found no help there. Since this is a docking station I thought I might need to try the SATA or Intel chipset drivers from the dell site instead, however I'm not really sure and I need to work on this laptop in the meantime.

• configure a Macbook Pro to use external monitor at boot (Debian Linux)

  - by Eric

  In the spirit of reuse, I've installed Debian (version 6.0.5 "squeeze") on my wife’s old Macbook Pro (circa 2009 or so), to repurpose it for various tasks. The catch is the display is flaky. It will last a random amount of time, between 2 minutes and 2 hours, before freezing and graying out. This is a known issue with that generation of MBP. Fortunately it’s no problem for me, as I plan to use it with an external monitor anyway. Which brings us to the problem: How do I configure this thing to output to the external display by default, and hopefully disable the built-in LCD? The ideal solution would be to modify a setting in the EFI (BIOS), but I’m not holding out much hope for that. Next best thing would be a kernel option I can pass to the NVIDIA driver. What won’t work is a solution that doesn’t give me a display until X starts. I need to have console access, especially given that the built-in LCD is dying, and any day now might give out completely. So far I haven’t been able to find anything online. lspci says I’ve got an NVIDIA GeForce 9400M Help is much appreciated! Eric PS if this question is better suited to the Unix & Linux area, pls advise and I will move it.

• Multiple Video Cards - Stuttering

  - by jstawski

  I have two video cards: - XFX PVT84JUDD3 GeForce 8600GT XXX 256MB 128-bit GDDR3 PCI Express x16 SLI Supported Video Card - EVGA 256-P1-N399-LX GeForce 6200 256MB 64-bit GDDR2 PCI Video Card both running the same set of drivers on Windows 7 64-bit. When I work with 2 monitors connected to the 8600GT card everything works smoothly. When I connect the third one to the 6200 then Windows works well and all of a suddon the screens turns black for up to 5 minutes. Then it goes back and at some random interval it goes black again. I can still see the pointer and hit CTRL+ALT+DEL and see the menu to log off, bring the task manager, etc. I've tried changing the 6200 to another PCI slot and the error persists. I've tried connecting 2 monitors only one to each card, same problem. Tried swapping them, mixed and matched the monitors to see if it was a problem with the monitor and my conclusion was that it is not the monitor. The problem also occurred with Vista 64 as well. What could be generating this problem? Can it be the fact that they are different interfaces? Maybe the Motherboard? Should I change something on the BIOS? What do you guys think?

• Windows Server 2008 R2 Virtual Network Setup

  - by jpearl01

  Some background: I'm very much new to networking in general, and virtualization in particular. I'm trying to set up a series of VMs as we are transitioning to a thin client setup. I have been supplied a limited number of static ip addresses. The server is located in an offsite building which houses the network we use to connect to the internet, share folders etc. The setup I've been trying to go for is this: The host OS (Windows Server 2008 R2) is bound to one nic using one of the static ips (say, Nic1 and ip 10.255.6.61). I've set up another external virtual network attached to another physical nic , and a virtual private network attached to no nic. There is one VM running the same os (as the host). This VM is connected to both the external virtual network (and uses another static ip say Nic2 and ip 10.255.6.62) and also to the virtual private network (I gave it a static random ip 192.168.88.1 subnet mask 255.255.255.0). This virtual private network is connected to all the other VMs. I'd like to share the internet connection with all the other VMs on the private virtual network, and so I installed the RRAS role on the server connected to Nic2, and selected the option to share the internet over the vpn. I've run through the RRAS wizard a few times, trying different configurations, but none of them seem to be letting the other vms connect to the 'net. The vms seem to connect to the virtual private network fine, they are assigned an ip address and everything, but no internet, and no rest of the network either. The other problem is in general I connect to the vms with RDP. Will that be possible with a setup like this? i.e. will the vms show up as computers on the network? If not, what are my other options? Thanks! ~josh
