• Cannot Login as root

  - by Josh Moore

  At my work we ship our product on pre-installed servers as a software/hardware package. We are using open SUSE 10.3 for the OS and we setup and we always log in with the root user to do maintenance on the box. Recently we just had box returned to us that the customer said the could not longer connect to the box through the network interface. So when I started to work on the box I run into the this problem: At the command prompt to login i type the user name "root" and hit enter. Then even before it asks me for a password I get "Login incorrect". I have never seen this behavior before and could not find any information about it online. Does anybody know what is going on? Thanks.

• Why Windows Media Center (Vista 32-bit) unable to record TV Series?

  - by Alex R

  I can record individual shows just fine, but trying to setup the recording of a Series throws an error (something like, "unable to schedule, try restarting Media Center", pops up in the bottom right of the screen). Trying to access the "Other Showings" menu causes Media Center to crash ("check for a solution online" dialog comes up). The machine is a fresh reinstall of 32-bit Windows Vista from the HP recovery CDs, plus all Microsoft updates and service packs. Hardware: HP s3220n, AMD X2 5000+, 2GB RAM, 300GB free space on disk. Media Center came bundled. The "Media Center update for Vista" failed to install (it says, not appropriate for my computer). Any ideas? Thanks

• DH61AG's mythical 2 pin 19v power socket and is too low of votage bad?

  - by Nick Orton

  I have an intel dh61ag motherboard. It has an external 19v power adapter. It also has a 1x2 pin 19VDC internal power connector. Now I cannot find a psu or adapter or anything that will plug into this. In an intel forum, one person said that he plugged half of a 2x2 psu connector in and it worked. Since this would deliver 12v into a socket that asks for 19v, I suspect that this is a bad idea. I don't know much about hardware. Can anyone explain to me why this would be a bad idea?

• Switch to switch encryption over a wireless bridge (TrustSec?)

  - by metatheorem

  I am planning to connect an existing Cisco 3750 switch to a 3560C switch over a wireless PTP bridge. The bridge will be WPA2 protected, but I am looking for an additional measure of security between the switches to prevent other wireless access through either switch. They do not support IPSec, only 802.1Q tunnels, and buying additional hardware is not likely an option. I am looking into using TrustSec manual mode between the switches. After some effort reading into TrustSec and MACsec, I am mostly certain this is a good choice over the wireless bridge, keeping in mind it is a shared medium. Two questions: Can I reliably prevent other wireless traffic from accessing the switches using TrustSec? Does anyone know of any better options with the 3000 series switches?

• Do all domains on the same shared hosting server have the same IP or ID

  - by silow

  Here's what I've got: siteA.com and siteB.com are hosted on hostgator. They're hosted on the same account of a shared hosting server (not VPS or dedicated). script.php is an external site that each of these 2 sites are accessing. I noticed that when siteA.com or siteB.com access the outside script.php, the script identifies them both as 1a.12.12ab.static.theplanet.com (apparently because hostgator uses theplanet.com servers). The fact that they're identified as the same value isn't surprising because after all they're hosted on the same account /home/user123/public_html. What I'm wondering about is how about other websites that are hosted on the same shared hosting server, but under other accounts. Basically other websites that are under another developer's control, but just happen to share the same hardware (hosting server). Do they also have the exact same identifier 1a.12.12ab.static.theplanet.com or that changes by account?

• DNS Pointer to old server name

  - by TechKnow Dude

  We have a SBS2003 server that was migrated to a new hardware platform, the computer name has changed but the domain is the same. The desktop's are trying to do offline files to the old server name. There is a nslookup entry for the old server name and a DNS entry for the old server. How do we safely remove the old DNS entry without breaking the computer offline folder storage locally. Can we change the pointing location on the offline file storage to point to the new server name.

• Exchange Failover Solution

  - by Dan

  I've been given the task to come up with an exchange solution that will support 200 users total throughout 4 states. 1GB per user. It needs to have a failover solution,The failover must reside in another location. There is an mpls that connects the locations. I am hoping to get recomendations on hardware, software setups. I recently worked with some big name reps and they steered me in the wrong direction and now I'm a few days away from my proposal date with bogus quotes and scrambling for a solution. I used to manage a standalone 2003 exchange server for years and am at a loss now with figuring out a clustering/failover...Any help would be greatly appreciated. thank you

• Top causes of slow ssh logins

  - by Peter Lyons

  I'd love for one of you smart and helpful folks to post a list of common causes of delays during an ssh login. Specifically, there are 2 spots where I see a range from instantaneous to multi-second delays. Between issuing the ssh command and getting a login prompt and between entering the passphrase and having the shell load Now, specifically I'm looking at ssh details only here. Obviously network latency, speed of the hardware and OSes involved, complex login scripts, etc can cause delays. For context I ssh to a vast multitude of linux distributions and some Solaris hosts using mostly Ubuntu, CentOS, and MacOS X as my client systems. Almost all of the time, the ssh server configuration is unchanged from the OS's default settings. What ssh server configurations should I be interested in? Are there OS/kernel parameters that can be tuned? Login shell tricks? Etc?

• Does RAID negatively affect non-RAID devices?

  - by Django Reinhardt

  I am running Windows 8 on an SSD, and it's all running swimmingly, but I want to store documents on two HHDs (not SDDs) running under RAID 1. My motherboard has two SATA controllers, both set to AHCI. On the 3GB/s controller, all four ports are used (1 Bluray Optical Drive, 1 Spare HD, and the 2 I wish to turn into a RAID 1 drive). Windows is on the 6GB/s controller. Like so: So my question is: If I turn these four ports (on the 3GB/s controller) into a RAID controller, will that negatively affect the non-RAID hardware plugged into it? I.e. Will the HDD or Bluray drive be slower/incompatible with being plugged into a non-AHCI controller? Thanks.

• Windows freezes, showing a random color or pattern

  - by Manu

  I have a PC with windows 7, and I'm experiencing random freezes with increasing frequency. After some time (from 30 minutes to a few hours) the screen will shows a random color or pattern (vertical lines) and nothing works anymore, I need to reboot manually. I've checked the events log, but nothing is shown except for the unexpected reboot. I've tested the RAM with Memtest86+ 4.20, and the graphics card with FurMark 1.10.3, no errors have been found. I've updated the graphic drivers and openned the case to remove dust, but the issue is still there. Also, the problem doesn't seem to arise when I'm playing games fullscreen, but when I'm surfing the web, using itunes, or coding. My hardware is as follows : intel core i5 750 CPU, ATI Radeon HD 5670 graphics card, ASUSTeK P7P55D motherboard, two 2Gb KINGSTON DDR3 ram sticks, 2 SATA hard drives, a Netgear dongle for wifi.

• Ubuntu 9.10 Dowload Speed Very Slow

  - by Don

  I'm running Ubuntu 9.10 desktop and I'm new to the Linux world, so bear with me. I'm on a corporate network of 3 T1s shared across 50-60 users. I typically get about 300 KB/sec for downloads, but for whatever reason, the Linux box will start out in that range, then drop to less than 1KB/Sec sometimes. Doesn't seen to matter where I'm downloading from. Right now I'm trying to get Eclipse for PHP and it's running at 3-6KB/sec. Getting the updates for the system will also drop to very slow rates. Our IT person has set up the machine to get the same 10.0.0.x address when it starts, and moved this IP to bypass our Proxy/Firewall going out, so that shouldn't be the issue. Can anyone recommend something I can try to better diagnose the problem. Again, I'm new to the Linux world and the hardware/OS setup side in general (coming form more of a coding background). Thanks for any advice.

• Why is only one domU giving me the "time went backwards"?

  - by Paul Tomblin

  I'm setting up a replacement server for one that was working ok but is having hardware issues. The original server is i686 (Pentium III), but the new one is amd64 (Xeon). Everything is working fine, except one of the three domUs is giving me the "clocksource/0: Time went backwards" error. The Debian Wiki says what to do if all your domUs are getting this error, but not what to do if only one of them has. The "tenants" on my domUs have done some messing about with the systems I configured for them. I don't know what the user of that particular domU might have done.

• Very frequent "Server not found" messages

  - by Village

  Recently, while browsing and clicking or typing an address, I get: "Server not found", "Connection was reset", or a half-loaded page. Usually the page loads instantly after clicking reload, but this means I must reload on every page. Images on one site, but stored at a different server don't load until reloading for a second time. Clicking "submit" on many sites frequently doesn't work unless I reload many times. Sometimes sites load, but without colors and formating, appearing as if they would in Lynx. This seems to happen with every Web site. My Internet service claims everything on their end is fine. This happened a day after running an update in aptitude. I have not updated any hardware. I have tried clearing Iceweasel's cache. I do not have any router or other equipment. What could be going on? How can I troubleshoot this? PPPoE connection, Iceweasel 3.5.16, Debian 6

• Running multipul lines through a server.

  - by Kevin Roberson

  I am looking to buy numbers in bulk on DIDx.net. After I purchase the numbers in a particular area code, I want to forward those numbers to other numbers that are outside of that area code. This way it will be seen as a local call versus long distance. I have the customers but I don't have the system I need. I have read about Asterisk, VOIP, SIP, and BYOH. But I have no clue what will be the best system for me. Does anyone have any idea what my next step should be when it comes to hardware and software? Or what type of operating system I should use? I basically want to set up a system like GoogleVoice & Phonebooth.

• Windows 8 switch user is very slow

  - by Chris Weber

  I recently upgraded to Windows 8 from Windows 7. One major annoyance is how slow the "switch user" command is. In Windows 7 switching users was fairly fast. I've got an SSD drive with pretty good hardware, so I'm suspecting it's something with Windows 8, either a defect, or the fact that I upgraded from Windows 7 instead of doing a clean install. Anybody have this problem? My wife is complaining enough about Windows 8 and this is one of the biggest complaints.

• XP SP3 PRO - Delayed write failed $mft- can I get which particular file caused the problem ?

  - by user35020

  Hi - I sometimes get that error when resuming from hibernation : Delayed Write Failed : Windows was unable to save all the data for the file G:\$Mft. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere. I know this is caused because the hard drive (G:, a usb external drive) which was plugged in when I hibernated was not read at the right moment - or sometimes I simply forgot to plug it when resuming from hibernation. My question is : is there any way to see which particular file/folder/folder status/don't know what failed to be written ? Hard drive functions correctly before and after - no problem. Is there a detailed log someplace or a utility ? Searched and searched but nothing. Thanks for any help !

• Sharing files between multiple computers?

  - by Koalatea

  At my school, we have 13 iMacs that we use to make our yearbook. Currently our school has some servers for us, but since we work with so many files ( thousands of pictures, most of which are ~3MB ) it slows down far too much. Is there a way to better share files between our computers? We are on a wireless network and the whole school shares the same servers, we have around probably 400 computers in the school. Is there a hardware fix I can do? Something like buying an external and hooking only yearbook computers to it?

• Hylafax with serial over IP modem

  - by zero_r

  I'm looking into virtualizing a Hylafax server which currently runs on a dedicated hardware running CentOS with a Divalogic card. The main issue obviously is, how to connect the modem to the VM. There are serial over IP devices available at digi.com. Maybe there are others? Regarding digi.com devices, as far as I understood one can install the RealPort software and then have a /dev/ttySx device presented to the Linux server. This device then can be used as serial connection to the modem. Does someone have such a configuration in place? Or does someone have another idea to virtualize a Hylafax server (outbound faxes only). Thank you in advance

• Can't print graphic from Publisher to pre-printed document

  - by Michael Itzoe

  I have a client who was given a stack of 8.5x11 tri-fold (unfolded) brochures printed on standard printer paper that they need to add their bulk mail permit stamp to. They've created a Publisher document with the stamp. If they print the document to standard paper in the tray, it prints fine. When they load the brochures into the tray, the brochure feeds through the printer but the stamp doesn't print. The stamp document is also 8.5x11. The printer is a Canon MF4300-D44. I can remoted in, but obviously have no access to the hardware. Any ideas?

• Windows 7 stopped booting

  - by jstawski

  I have a laptop which after shutdown it stopped booting. I tried repair, safe mode, and even start with Windows 7 Installation. The screen just goes blank with a mouse pointer that I can move around. I removed the harddrive from the laptop and connected it to my desktop using an External HD casing. The computer recognizes the disk, but it seems like it can't read it. If I go to My Computer it shows up, but it doesn't display usage information. When I double click on the drive it sits there as if it was loading something and eventually shows "G:\ is not accessible. The parameter is incorrect." Disk Management and Diskpart also take forever to load and when it does it shows the drive. My question, do you think this is a hardware problem or some corrupted sector? How can I try to fix the drive without formatting it? Thanks...

• Can a RAID disk setup crash if only 1 hard disk fails?

  - by Steve Rodrigue

  I am a web developer. I have not much experience in hardware. For this reason, I use managed servers. This morning, one of the drives in our setup failed. However, the full site went down. I asked my web host what happened and he replied that the hard disk failed in such a way that the RAID controller couldn't work properly. Do you guys ever seen that before? Is it possible? Thanks for any help on this guys. I need to know if my web host is honest with me. Steve

• solving network connection problem on xp

  - by doug

  Hi there I feel so stupid, because I have to fix my dad computer(which was mine years ago). So it is an old computer on which I have installed windows xp and the drivers for main-board. The device manager says that I have no more problems with the hardware. That computer has to connect to a router from my room but it doesn't. On ping 192.168.2.1 I get "Request time out"., The other computers are connecting to that router. Only the old computer doesn't connect to the LAN and later to the internet. Also it doesn't get a good IP(from the same class). After running ipconfig command I know that i have an IP with 169.... What can I do? Do you have any tips for me?

• Can I run Ubuntu directly under Windows 8?

  - by huahsin68

  Text below is extract from the article, Windows 8 Tip: Virtualize with Hyper-V. Better still, Windows Virtual PC offered a feature called XP Mode, free for users of Windows 7 Professional, Enterprise, and Ultimate, which included a full working copy of Windows XP with Service Pack 3. But the big deal here is that as you installed applications in the virtual copy of XP, they would be made available through Windows 7’s Start Menu. And you could run these applications, side-by-side, with Windows 7 applications on the Windows 7 desktop. It was a seamless, integrated experience, ideal for those one-off application compatibility issues. I was thinking to install VirtualBox in Windows 8 and then run Ubuntu as guess OS. Since Hyper-V is a Type-0 hipervisor, may I know does this bring the same benefit if I have Ubuntu Linux install as a virtual guess OS? Meaning, if I turning the Ubuntu on (the guess OS), does the Ubuntu still able to access the hardware information like nVidia display card or processor information? I'm just curious to know can this be done?
