• sata hard drive failed

  - by M. Shehryar

  Dear friend, initially my dual core PC started shutdown and re-start by itself after adding 1 GB ram and up-grading the graphic card. Then refused to boot. I restored the window ghost but failed to boot. I tried to install new window but installation failed after coping the window files. tried to install old vista lonhorn. It inspected found errors, fixed them but ultimatly failed to be installed. Once again restored the ghost through acronis but failed to boot. At the end attached as slave with another pc but it was not visible. Even acronis could not see it or its partitions. Only bios can see it. It seems that no file system is available on the drive. My data on drive is very important. Please help me how to revover my data. Drive brand is Samsung, cap is 160 GB and file system was NTFS.

• FreeBSD rc.d script doesn't work when starting up

  - by kastermester

  I am trying to write a rc.d script to startup the fastcgi-mono-server4 on FreeBSD when the computer starts up - in order to run it with nginx. The script works when I execute it while being logged in on the server - but when booting I get the following message: eval: -applications=192.168.50.133:/:/usr/local/www/nginx: not found The script looks as follows: #!/bin/sh # PROVIDE: monofcgid # REQUIRE: LOGIN nginx # KEYWORD: shutdown . /etc/rc.subr name="monofcgid" rcvar="monofcgid_enable" stop_cmd="${name}_stop" start_cmd="${name}_start" start_precmd="${name}_prestart" start_postcmd="${name}_poststart" stop_postcmd="${name}_poststop" command=$(which fastcgi-mono-server4) apps="192.168.50.133:/:/usr/local/www/nginx" pidfile="/var/run/${name}.pid" monofcgid_prestart() { if [ -f $pidfile ]; then echo "monofcgid is already running." exit 0 fi } monofcgid_start() { echo "Starting monofcgid." ${command} -applications=${apps} -socket=tcp:127.0.0.1:9000 & } monofcgid_poststart() { MONOSERVER_PID=$(ps ax | grep mono/4.0/fastcgi-m | grep -v grep | awk '{print $1}') if [ -f $pidfile ]; then rm $pidfile fi if [ -n $MONOSERVER_PID ]; then echo $MONOSERVER_PID > $pidfile fi } monofcgid_stop() { if [ -f $pidfile ]; then echo "Stopping monofcgid." kill $(cat $pidfile) echo "Stopped monofcgid." else echo "monofcgid is not running." exit 0 fi } monofcgid_poststop() { rm $pidfile } load_rc_config $name run_rc_command "$1" In case it is not already super clear, I am fairly new to both FreeBSD and sh scripts, so I'm kind of prepared for some obvious little detail I overlooked. I would very much like to know exactly why this is failing and how to solve it, but also if anyone has a better way of accomplishing this, then I am all open to ideas.

• 2 servers on 2 networks in same office

  - by irot

  Hello Gents, My office doesn't have a "server guy" in employ, so I'm stuck with having to fix server issues for now. There are 2 servers in our office, both are file/web servers only accessible via LAN. They are currently on the same network, so no issue there. Problem is, we recently got a static IP to use, but it's with a different ISP, so now we have 2 routers in our office. I would like to open one of the servers to the public as a web/FTP server. But if I hook a server up to the new router, users will no longer be able to access the files shared on that server (because they're on different networks). How can I go about making one server accessible to the public using the static IP line, but still able to share the files on it to the users connected to the other network? The server I want to make public is running Windows Server 2008, the other server Windows Server 2003. And as far as I know, IP addresses are assigned by the router. I'm just a developer, don't know much about networking. Thank you in advance.

• Local SSL connections are causing redirect loop (after Ubuntu update)

  - by codeinthehole

  Following a recent Ubuntu update, my local websites are no longer serving their pages over SSL. For example, my .htaccess file attempts to ensure /sign-in is always served over HTTPS: RewriteEngine On RewriteCond %{HTTPS} off RewriteCond %{REQUEST_URI} /sign-in RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,QSA,R=301] However when I make a request to /sign-in on the domain site2-local , I get the error "The page isn't redirecting properly" with the following in /var/log/apache2/error.log [Tue Jun 08 12:20:57 2010] [info] [client 127.0.1.1] Connection to child 0 established (server site1-local:443) [Tue Jun 08 12:20:57 2010] [info] Seeding PRNG with 656 bytes of entropy [Tue Jun 08 12:20:57 2010] [info] Initial (No.1) HTTPS request received for child 0 (server site2-local:443) [Tue Jun 08 12:20:57 2010] [info] Subsequent (No.2) HTTPS request received for child 0 (server site2-local:443) [Tue Jun 08 12:20:57 2010] [info] Subsequent (No.3) HTTPS request received for child 0 (server site2-local:443) [Tue Jun 08 12:20:57 2010] [info] Subsequent (No.4) HTTPS request received for child 0 (server site2-local:443) [Tue Jun 08 12:20:57 2010] [info] Subsequent (No.5) HTTPS request received for child 0 (server site2-local:443) [Tue Jun 08 12:20:57 2010] [info] Subsequent (No.6) HTTPS request received for child 0 (server site2-local:443) [Tue Jun 08 12:20:57 2010] [info] Subsequent (No.7) HTTPS request received for child 0 (server site2-local:443) [Tue Jun 08 12:20:57 2010] [info] Subsequent (No.8) HTTPS request received for child 0 (server site2-local:443) [Tue Jun 08 12:20:57 2010] [info] Subsequent (No.9) HTTPS request received for child 0 (server site2-local:443) [Tue Jun 08 12:20:57 2010] [info] Subsequent (No.10) HTTPS request received for child 0 (server site2-local:443) [Tue Jun 08 12:21:12 2010] [info] [client 127.0.1.1] (70007)The timeout specified has expired: SSL input filter read failed.

• Can I get a domain controller not to act as DNS for the members?

  - by rsw

  Hi, Let me try to explain my current setup. I have one linux machine acting as DHCP and DNS (dhcpd3 and bind) in my network. This works fine, all computers I hook up to the network gets an IP address and proper DNS servers set. Let's call it 10.12.0.10 However, we also have a Windows Server 2003 Domain Controller in our network to which we add our Windows computers (running XP), let's call it 10.12.0.20. I noticed that when I run 'nslookup' on one of the windows machines, it says that the primary DNS is 10.12.0.20. This have not been much of a problem since: The Windows clients are stationary The Windows server in itself point out my real DHCP/DNS, since I can reach everything specified in it However, this turns out to be a problem when we use Laptops. They connect to the domain here and gets a DNS server, but when the user travels or connect the computer from home, we hit a problem. They are connected to their internet, but their DNS is 10.12.0.20 which they can't reach since they're at home and not at the office network. I solved this by removing the register key called "NameServer" with the value 10.12.0.20, but it gets set again whenever they logon to the domain the next time (when they get back to the office). Can I somehow make the computers take whatever DNS server they are handed when connecting to the internet or a home network, instead of always trying to reach the Domain Controller?

• What steps should I take to debug this non-starting hvm virtual machine?

  - by Ophidian

  I have a dom0 machine running CentOS 5.4 with all the latest updates using Xen as my hypervisor. I am using Xen in part because this machine was set up prior to KVM being included in RHEL, and in part because KVM's network bridging configuration is not nearly as simple as Xen's. The dom0 machine is headless and I do all of my VM management via virsh from the command line. I have two hvm domU's: A web server running CentOS 5.4 A mail server running Gentoo Both VM's are backed by LV's on the dom0 but do not use LVM in the domU. Both have virtually identical libvirt configurations (differing by expected things like name, UUID, NIC MAC, VNC port, etc). The web server domU (WSdomU hereafter) does not start since applying the most recent kernel update (kernel-xen-2.6.18-164.15.1.el5.x86_64 and kernel-2.6.18-164.15.1.el5.x86_64 for the dom0 and WSdomU respectively). By 'not start' I mean it appears to be running but it does not use an CPU cycles, does not bring up a graphical console, and does not respond on the network. The WSdomU is listed as no state rather than the normal running or blocked in xentop. The mail server domU starts fine and functions normally. Here are the steps I have taken so far that did not solve the problem: Reboot the dom0 to see if things come up on their own Check xen dmesg on dom0 Check xend logs (a cursory viewing did not show anything blatant; specific suggestions of things to look for would be appreciated) Attempted to connect to the WSdomU's graphical (VNC) console from the dom0 Shutdown the mail server domU and attempt to start the WSdomU Check the SELinux labels on backing LV's (they're the same) Set SELinux to permissive and attempt to start the WSdomU Use virsh edit to try tweaking the WSdomU config virsh undefine, reboot, virsh define the WSdomU config dd the WSdomU LV to an .img file, copy it to my Fedora desktop and run it under KVM (works fine) What steps should I take next to debug this? I will edit in any additional configuration's requested in the comments.

• Computer Freezes with "Bugcheck 0" on Windows 7. How do I figure out why?

  - by George Stocker

  After about 10 minutes of running, my computer will hang, exhibiting the following symptoms: Both monitors act as if there is no image being sent to them (on, but blacked out) The CAPS Lock key on the keyboard will not respond. The computer appears to still be running: CPU Fan is whirring. When I reboot, Windows says "The previous shutdown was unexpected." I've enabled the 'don't automatically restart' on an error, and asked the computer to make a memory dump whenever it crashes, but it hasn't done either. The problem is that there's no bugcheck for me to go off of, so there's no way for me to determine what the cause is (I think). Here are my system specs: Intel Core 2 Duo E6750 Gigabyte P35C-DS3R w/ 4.00 GB (DDR2 Ram) Nvidia 8800 GT Windows 7 I've tried running the Windows Memory checker, but the system also freezes when using that after about 10 minutes as well. How can I diagnose the problem with no bugcheck and no ability to run a memory checker? Update Running Memtest86 also causes the computer to crash (looks like it doesn't make it through a full pass - it was only running for about 10 minutes when the PC stopped responding).

• Reconnecting OST with Exchange

  - by syrenity

  Hi. I have a quite big problem with customer's MS Exchange. The server got it's disk filled about 2 weeks ago, so it's currently offline. They plan to upgrade it, but not in hurry, as they use it mainly for OWA and back-up - the mails exchange is done via SMTP and POP3. Trying to diagnose some problem today, one of the users has (following the ISP instructions), removed the Exchange account from Outlook, which essentially left the OST orphaned. The user naturally didn't move the emails or any other data to the Archive / PST before, so these emails located on the OST only. So currently I'm trying to figure out how to restore them. There are 2 options: 1) Make the user buy some tool to convert them to PST, and import as archive / main Outlok file? 2) Reconnect the Outlook to Exchange (once it up), let it sync the old server content, then shutdown Outlook and replace the new OST with the old one, start Outlook again in offline mode and move these files to archive. 3) Any other method? Can someone advice what would be the best approach here? The used versions are Outlook 2007 and Exchange 2003. Thanks!

• Sane patch schedule for Windows 2003 cluster

  - by sixlettervariables

  We've got a cluster of 75 Win2k3 nodes at work in a coarse grained compute cluster. The cluster is behind a mountain of firewalls and resides in its own VLAN. Jobs of all sizes and types run on the cluster and all of the executables running are custom-made. (ed: additional notes on our executables) The jobs range from 30 seconds to 7 days in duration, and may contain one executable or 2000 sub-jobs (of short duration). Obviously we are trying to avoid the situation where our IT schedules a reboot during a 7 day production job. We have scheduling software which accomodates all of the normal tasks for a coarse grained cluster and we can control which machines are active for submission, etc. If WSUS was in some way scriptable (or the client could state it's availability for shutdown) we could coordinate the two systems and help out. Currently, the patch schedule is the Sunday after Super Tuesday regardless of what is running on the cluster. We have to ask for an exemption every time we want to delay patching a machine for a long running production job. Basically, while our group is responsible for the machines we have little control over IT's patch schedule. Is patching monthly with MS's schedule sane for a production Windows cluster? Are there software hooks in WSUS where we could say, "please don't reboot just yet"?

• Few questions about a good projector on my PC and tv?

  - by jasondavis

  I have always wanted a projector for my tv, satelite, cable, and even PC in a spare bedroom. Well it's more of a home office that I spend most my time in and the catch here is it is a small room. Room is only the standard 8foot tall. Room is about 13 feet wide on the wall where I would like to mount the project and the wall where the screen would be for it. So only about 13 feet away from projector to screen. I would like to know... 1) From experience or knowledge what would be a good projector I could hook up to my satelite box and also my PC? Cheaper is better in this case but I would still like the best image for my buck and something reliable. There is no sunlight in the room either to worry about. 2) From that distance of about 12-13 feet away, how big of a clear picture could I expect? 3) What kind of cables would I need to purchase and run through my attic to my cable/satelite receiver box as well as my PC? 4) These cables in question 3 would most likely need to be a good 15-20feet in length to reach, would I need anything special for that to work at those distances?

• Oracle: Getting ORA-01195 and ORA-01110 when attempting resetlogs

  - by MacAnthony

  I am trying to get our database to startup. When I login to sqlplus and do a startup, I get the message: Total System Global Area 534462464 bytes Fixed Size 2215064 bytes Variable Size 331350888 bytes Database Buffers 192937984 bytes Redo Buffers 7958528 bytes Database mounted. ORA-01589: must use RESETLOGS or NORESETLOGS option for database open So I do a shutdown, startup mount (which works fine) and then run: SQL> alter database recover using backup controlfile until cancel; alter database recover using backup controlfile until cancel * ERROR at line 1: ORA-00283: recovery session canceled due to errors ORA-19909: datafile 1 belongs to an orphan incarnation ORA-01110: data file 1: '/<path>/system01.dbf' SQL> alter database open resetlogs; alter database open resetlogs * ERROR at line 1: ORA-01195: online backup of file 1 needs more recovery to be consistent ORA-01110: data file 1: '/<path>/system01.dbf' I know I've used instructions to get me past this error before, but I seem to be having trouble tracking it down. A bit of history: We wanted to refresh the data in this from another db so we attempted to do a expdb/impdb into this instance. The impdb did not complete correctly and got an end of file error message in it and hung (I still have the message in a log if it's important). Since the instance would start at this point, we decided to use the hotbackup process we have to restore the db. The hotbackups are from another server/instance. We went through the same process 2 weeks ago. At the point of recreating the control file is where we got to the issue above.

• Computer always freezing after random periods of time. No errors listed.

  - by Wesley

  Hi, all. Here are my specs beforehand: AMD Athlon XP 2400+ @ 2.00 GHz, 160GB IDE HDD, 128MB GeForce 6200 AGP, 2 x 512MB PC3200 DDR RAM, CoolMax 350W PSU, 1 x CD-RW Drive, 1 x DVD-ROM Drive, FIC AM37 Mobo, Windows XP Pro SP3 My desktop freezes after random periods of time but there are no errors listed in the Event Viewer after a forced shutdown and restart. A couple months ago, I found that when it froze, the floppy was being accessed at the same time. So, I disconnected the floppy (since I never used it anyways) from the power supply and motherboard. Everything was working fine and the computer never froze. This past Christmas break, I left for a Conference and when I got home, the computer kept freezing again. So, this time, I just disconnected the DVD reader (from mobo and power) and started it up. Still, it froze almost right away. Then I found some older sticks of RAM (2 x 256MB PC2100 DDR) and swapped them in. Everything worked fine again after that. I even swapped the 2 x 512MB PC3200 DDR RAM back in and everything worked okay. Then it started freezing again, and I tried all possible RAM combos, still freezing within 5-10 minutes of startup. One thing I've realized is that the floppy drive is still listed in My Computer and I uninstalled it from my Device Manager already. There were no software errors, and I uninstalled the most recent software, with no effect. Still, I have no idea what is wrong because everything ran fine before that. Any suggestions? EDIT: Still have yet to buy some blank CD media to use Memtest86+. However, would a lack of virtual memory cause the computer to freeze? EDIT2: So after a long time, I ran Memtest86+ and all is well. Turns out though, after removing my original DVD reader and replacing it with a DVD-ROM drive, there is no freezing whatsoever! Thanks for all your suggestions!

• UPS power requirements for server

  - by captainentropy

  Greetings! So, I just placed an order for a new server. The company recommended that I get a 3000W UPS. (!) As best as I could I calculated the following wattage consumption based on benchmarked data or datasheets provided by the manufacturers of each component: number watts **total watts** MoBo 1 240 240 CPUs (E5540) 2 80 160 RAID cards (3ware) 2 18 36 RAM (6x4GB) 6 3 18 DVD drive 1 7 7 floppy 1 2 2 RE4 drives 8 7 56 WD20 drives 8 6 48 Intel X25 SSD 2 0.15 0.3 total = 567 So that is for the PSU requirements only. The PSUs in the machine are a 720W for the master node and 800W each for two subsystems. That's a total of 2320W that can be delivered by these PSUs. But that is 4X the amount being consumed, at most, by the components. I didn't count case fans or the eSATA card (3W maybe?) or what the PSUs themselves require but assuming I double or triple my calculations I'm not even remotely close to the 3000W UPS I was suggested to get. They run at least $1100. I could get a 2000W for about $750 or a 1500W for $450 and still be well over my estimated power need. I don't think I need a whole lot of run time in the case of a power outage, maybe 20 minutes max, enough time to shutdown if the power doesn't come on within 5-10 minutes. Any thoughts? Am I off on my calculations? Did I overlook something major? If so what are your suggestions for a UPS? Thanks!

• xauth, ssh and missing home directory

  - by flolo

  We have several servers, and normaly everything works fine, except now... we get a new aircondition installed. This takes 36 hours and for this time almost all servers got shutdown, only 2 remaining servers run for the most important tasks (i.e. accepting incoming email, delivering some important websites, login-server). Everybody was informed that when they need appropiate data from the homedirs they should fetch it before take down. Long story short: Someone realized that he have run a certain program on one of the servers. No Problem, he can remote login into our login server and run the programm there without home directory (binaries are local and necessary information can be copied to the /tmp). That works like a charm until... ... the user needs to run a GUI programm. I find no easy way to make it running, usually ssh -Y honk@loginserver is enough but now the homedirectory is missing and ssh is not able to copy the cookies into ~/.Xauthority (as the file server with the home directories is down). Paranoid as all systemadmins all X-Server just listen locally not on tcp ports, so no remote X connection possible SSH config is waterproof - i.e. no way to set environment variables. My Problem is, that the generated proxy MIT cookie from ssh get lost as the .Xauthority doesnt exist. If I could retrieve it somehow I could reenter it a .Xauthority in /tmp. The only other option (besides changing the config) which came to my mind is, makeing a tunnel (netcat, or better ssh) from the remote host to the loginserver and copy the cookie manually (not sure if it the tcp-unix domain socket stuff works as expected). Any good suggestions (for the future - now our servers are already up)?

• Mystery 0xc0000142 error on starting java from a service, as a different user.

  - by cpf

  This is a very convoluted setup, but effectively this is what goes down: Manager service (which I don't have control over) running as admin user X starts my executable, which then starts Java as user Y using the standard c# StartInfo.Username/Password controls. Now, from a basic (not elevated or anything, just admin) command prompt I can run that executable, and Java pops up and works fine, running perfectly under the user it should be. When the service runs the same executable, however, Java silently fails. The only hint I see is this series of events in the event viewer: Service starts "Application popup: java.exe - Application Error : The application was unable to start correctly (0xc0000142). Click OK to close the application. " (googling this reveals a lot of scam sites telling me to use their "free antivirus to fix 0xc0000142 errors easy!"... sigh) Service stops (the java shutdown propagated, which is supposed to happen) And here's what process explorer has for the failure: As you can see, everything shows as a success. Now, I think this might have something to do with the permissions (the user java.exe is running under has traverse permission for the entire drive and full permissions to Directory A, which is where the .jar is), but I just can't fathom how something that works fine from the command line (and, this is an upgrade, the previous system without the user-switching aspect works fine from the service) can fail with such a cryptic message and little showing up in logs.

• SSH Interactive mode not working

  - by Ekin Koc

  I have a Debian based linux server running for a year or so, without any problems. A couple of days ago, ssh interactive mode stopped working for no reason. I mean, I can open an ssh connection just fine, the server greets me with shell but I just can't type anything. However, if I send commands like this: ssh [email protected] cat /var/log/messages, I get the response. I dug through several logs and found one message, which feels remotely relevant to the problem; sh kernel: [10222733.062511] ------------[ cut here ]------------ sh kernel: [10222733.062522] WARNING: at /build/buildd-linux-2.6_2.6.32-39-amd64-7yVIH2/linux-2.6-2.6.32/debian/build/source_amd64_none/drivers/char/tty_ldisc.c:738 tty_ldisc_reinit+0x46/0x7b() sh kernel: [10222733.062526] Hardware name: PowerEdge R210 II sh kernel: [10222733.062528] Modules linked in: ipt_MASQUERADE iptable_nat nf_nat nf_conntrack_ipv4 nf_conntrack nf_defrag_ipv4 ip_tables x_tables sha1_generic arc4 ecb ppp_mppe ppp_async crc_ccitt ppp_generic slhc loop snd_pcm snd_timer snd soundcore snd_page_alloc i2c_i801 i2c_core pcspkr evdev joydev dcdbas container button processor ext3 jbd mbcache sg sd_mod sr_mod crc_t10dif cdrom usb_storage usbhid hid mpt2sas ahci ehci_hcd libata scsi_transport_sas usbcore bnx2 nls_base scsi_mod fan thermal thermal_sys [last unloaded: scsi_wait_scan] sh kernel: [10222733.062568] Pid: 8662, comm: sshd Not tainted 2.6.32-5-amd64 #1 sh kernel: [10222733.062569] Call Trace: sh kernel: [10222733.062572] [<ffffffff811ff056>] ? tty_ldisc_reinit+0x46/0x7b sh kernel: [10222733.062574] [<ffffffff811ff056>] ? tty_ldisc_reinit+0x46/0x7b Is there any way to get back the sshd working in interactive mode?

Should I go ahead and request a physical reboot?

• why Thinkpad T410s intermittent keyboard death?

  - by patrickmdnet

  I have a Thinkpad T410s running Windows 7 64-bit. I have had it for three months. It has the latest BIOS (1.41) and trackpad drivers. In the last week I have started to notice that the keyboard intermittently stops working. Specifically, keystrokes have no effect, including Fn-F12 (shutdown) and Ctrl-Alt-Del. The LED on the capslock key does not turn on or off. Whatever state the lighted keys (e.g. mute) were in remains. The trackpad and trackpoint work properly, and I can close apps and properly shut down the machine. When I attach a USB keyboard it is recognized, but no keys work. If I run the Lenovo keyboard test, all the keys register properly and the caps lock light works again. When I quit the test app, the caps lock light stops working. If I hit Fn-F12 while the keyboard test is running, it goes into hibernation. When the machine comes back from hibernation, once I exit the keyboard test I again cannot do any input on the keyboard. I'm pretty convinced there is a software or driver problem. I never saw this the first three months I had the laptop. I do not recall installing anything recently. I am sure I've received some Windows security updates. I tried using wired networking instead of wireless - no difference. There doesn't appear to be any inciting event; it usually happens when I am working over ssh. I switched from rxvt+ssh to Putty and the problem still occurs. Any ideas?

• Windows7 corrupted profile - prevention exists?

  - by Radek

  I have dedicated Windows7 (not on domain) virtual machine for overnight automation testing. Some commands (mySQLdump, tscon.exe) must be run under administrator account. Last week administrator account's profile was corrupted. I fixed it by renaming it in the registry and logging in as administrator. And today it is corrupted again. I use administrator account only to run above commands via runas. Also the computer is restarted via cmd - shutdown command - quite often. Especially every night before automation testing starts. I checked the comp for viruses - did full scan using avast although I believed that the comp is clean. Any idea how to prevent the profile to get corrupted again? update So the first log entry in event log is today from 1.15am and one of my scripts ran runas command as administrator exactly at 1.15am. It was second time that runas war executed though after the testing started. The same happened second day in a row. Before the testing starts I need to copy one file that is locked. So I run handle.exe from runas to unlock it. That is what I think causing the profile to get corrupted. I am not able to reproduce it by myself. The message from event viewer is Windows cannot load the locally stored profile. Possible causes of this error include insufficient security rights or a corrupt local profile. DETAIL – The process cannot access the file because it is being used by another process.

• kill a hung mount process

  - by John P

  I have a virtual machine drive that ran out of space, so I shutdown the VM, extended the volume using lvextend. After resizing the partition (ext3), I ran e2fsck on it, and it found and corrected errors. Unfortunately, when I ran efsck one more time, there were more errors that had to be fixed. I went through 3 rounds of e2fsck before I decided to try mounting it to clean up some space manually. I tried mounting it, but the mount process hung. I tried to "kill -9" the mount process, but that did not kill it. I killed the parent process, but that did not kill it either. Any ideas on how to kill a rogue mount process?

• KVM Guest Reboot Loop

  - by javano

  I have been pulled into a situation where a KVM server (CentOS 6.2) lost power and upon reboot one of the guests hasn't started up again (XP SP3). I have SSH'ed in and someone must have changed something relating to the hyper visors prior to the power loss, but not rebooted all the guests. This particular guest wouldn't start because it was configured to use /usr/bin/qemu-system-x86_64 which isn't there now (assuming it was before?). I changed it to use /usr/libexec/qemu-kvm as this is what all the other guests on this server seem to be using, and its booting up. Using virt-manager on my local machine I can connect to the display of the XP machine and it gets as far as this screen; http://support.gateway.com/emachines/issues/2-1131285152-01.gif The problem I face now, is that which ever option I choose the machine just reboots. So it's and endless loop. I thought that perhaps a file system error maybe present due to the unclean shutdown. There is an XP SP3 ISO mounted under the guest, which I booted from in an attempt to access the recovery tools, but I don't have the Administrator password! I am out of ideas, and it's turning out to be quite the conundrum. Should I use a 3rd party live CD to test the FS for errors? How else can I trouble shoot these restarts?

• Power issues Foxconn Barebones kit

  - by alpha1

  I have a Foxconn R20D2 bought about a year and a half ago. It ran fine for a while and then around last summer it started having power issues. I chalked it up to changes in electric current due to the overwhelmed grid when people turn on their AC units, but this problem has stayed for all year, shutting off randomly, shutting off when i turn on a vacuum and similar problems. Now that its summer again, the box basically sits there all day cycling itself, and now has gotten to the point it tried to boot and after 3 seconds, fails, shuts off and tried again. I know its power related, it runs opensuse linux and there are never any shutdown logs or anything of that sort. As the weather got hotter i noticed it happening more and more, and it most often happened in the morning, i presume as people woke up and turn on the AC. The power supply is a Chennel well technology co LTD model DSL-150. 150W max output. Its an intel atom dual core, with 2 sata drives, no CD/floppy etc, recently upgrades from 2 to 4gb of ram. It runs at 104 degrees Fahrenheit all the time almost. Any way i can test the power supply or anything else to try to fix it? Im a software guy, not hardware so im at a complete loss here, thanks for all assistance you can provide! EDIT: The switch on the back that says 230 or 115 is set to 230. If im in the USA, could that be causing the problems?

• How can something relevant to graphics completely kill a motherboard?

  - by leladax

  I was coding something in OpenGL and after a bug there was an 'OS slowed down' situation. After a few seconds the screen went blank and the laptop shutdown. Now not even a led turns on battery or not. It doesn't appear to be the AC or the battery since there was some battery when it died and when it's connected to the AC the laptop produces near the AC connection a very slight 'clicking' noise (very faint, one has to be very careful to notice it, I don't know if it was there forever tbh). I suspect the motherboard died, as in something from the point it gets AC or battery power and the point it actually feeds itself. But I can't figure out how that effect was produced by the OpenGL bug or graphics overheating. If the graphics died alone, it should at least give some indication that the laptop is barely alive, at least a led, a sound, anything, the laptop is instead completely dead (other than faint 'clicking' I mentioned). Does anyone have expert advice on this? I'm especially interested in any ideas connected to "graphics overheated/bugged ---- they killed motherboard". I have a very lengthy experience in that stuff as a hobbyist and it really puzzles me. It's not just a "AC died" situation I can easily google.

• how to set up dual wireless routers (G and N) with single broadband connection

  - by user15973

  A local cafe has an 802.11g wireless router attached to either an 8- or 12Mbs broadband connection. Although many customers still have -g devices, an increasing number are showing up with 802.11n devices (e.g. Mac laptops, iPads). The cafe owner is content with his router's area coverage, but he would like for his customers to be able to take advantage of the higher -n download speeds. He could simply replace the -g router with a -n router, but reportedly -n routers slow down considerably when servicing both -g and -n connections. Another option would be to buy the -n router, run an Ethernet cable between the two routers, and (of course) hook up the broadband connection to one of the two routers. Still another option would be to attach an ordinary, wired switch to the broadband connection and then attach both routers to the switch. Aside from the cost issue, what are the tradeoffs of those approaches? Which would you recommend, and why? Is there a better option than the ones I mentioned? Thank you in advance for your advice.
