  • Looking for home networking hardware and software advice

    - by phobos7
    Note: I originally wrote this up in a blog post. I've removed any affiliate links that I put in my original post to ensure I don't annoy anybody. I've recently moved home and I now need to go to the trouble of sorting out my home network yet again. We had Virgin broadband in Hertford but you can't get Virgin in the street we've moved to so I've had to go with O2 Broadband. Normally I prefer to use my own hardward, and previously used the DLink DIR-655 router which was great, but in this situation I am using the O2 Wirelss Box III since I only have an old Netgear DG834PN Wireless G modem router and I'd rather be using Wireless N. Anyway, the place we have moved into has only one phone point in the hallway, has the best TV point in one room and the best place to put the TV and other entertainment stuff in yet another room. So, networking the house up for Internet and TV is required. The diagram below shows the things that I'll have in my home network but there are three points where I'm not quite sure what hardware to us. Wireless Access Point/Bridge, that acts only as a wireless to wire bridge and not an AP, that links up a Media Centre/PC and a couple of consoles to the network. I'm pretty much settled on us an Acer Aspire Revo R3600 as my media PC, probably with Ubuntu or Windows and XBMC installed. Wireless Access Point/Bridge, that acts only as a wireless to wire bridge and not an AP, that links up a device that can decode and stream TV from a TV aerial across the network. The device that is connected to 2). At the moment I'm considering a HDHomeRun by SiliconDust. At the moment I'm considering either the TP LINK TL-WA701ND 150Mbps Wireless Lite N Access Point (very cheap at Amazon) or the Netgear 5 GHz Wireless-N HD Access Point/Bridge. I'd love to get some insight into what you would do in my situation. What Wireless Access Point/Bridge should I put at points 1) and 2)? What device should I choose for point 3) that can decode and stream a TV signal? Is the Acer Aspire Revo R3600 a good choice? ![alt text][6] Note 2: I've also posted this question on AVForums.

  • High CPU from httpd process

    - by KHWeb
    I am currently getting high CPU on a server that is just running a couple of sites with very low traffic. One of the sites is in still development going live soon. However, this site is very very slow...When browsing through its pages I can see that the CPU goes from 30% to 100% for httpd (see top output below). I have tuned httpd & MySQL, Apache Solr, Tomcat for high performance, and I am using APC. Not sure what to do from here or how to find the culprit as I have a bunch of messages on the httpd log and have been chasing dead ends for some time...any help is greatly appreciated.

  • Blank Screen After Login on Windows 7

    - by Leigh Riffel
    When unlocking a Windows 7 computer the screen briefly (less than a second) goes blank before showing the screen. Abound once a month (but sometimes within a few days) when I unlock my computer the screen doesn't come back from this brief blackout and stays black. Sometimes after five minutes or so the display will come back. Other times it has been blank for over 20 minutes, so I give up and restart the computer. It seems to happen more often when the computer has been locked for a longer period of time - I lock my computer several times a day, but the problem most happens when I come in at the start of the day. I have updated my video card and monitor drivers. I have two monitors driven by the same graphics card. The computer is a Dell Optiplex 740. When the problem occurs both monitors have a green light on to indicate that they are receiving signal. I've tried unplugging the monitors from the video card and turning the monitors on and off. The screen saver is set to one that is not blank screen. The Windows power settings are set to never turn off the display. When the problem occurs there is no significant disk activity occurring. When the problem occurs I can connect over the network to the hard drive on my computer. When the problem occurs I can't connect over the network with a VNC connection. The VNC client doesn't give an error, but also won't show the screen. The task actually seems to hang as I can see the task, but there is no window for it. This problem occurred when I was running a pre-release version of Windows 7. The hard drive was formatted for release version and the problem still occurs. I've been stopping some of my always running programs to see if one of them may be the culprit, but given the span between failures that will take some time to find the problem if it will even help at all. Some programs I have always running include IE, Firefox, Outlook, Evernote, Kana Reminder, Ditto, Macro Express, Timesnapper, and DisplayFusion. Any ideas appreciated.

  • An alternative to Google Talk, AIM, MSN, et al [closed]

    - by mkaito
    I'm not entirely sure whether this part of stack exchange is the most adequate for my question, but it would seem to me that people sharing this kind of concern would converge either here, or possibly on a more unix-specific sub site. Either way, here goes. Background Feel free to skip to The Question, below. This should, however, help those interested understand where I'm coming from, and where I expect to get, messaging-wise. My online talking place-to-go has been IRC for the last fifteen years. I think it's a great protocol, and clients out there are very good. I still use, and will always continue to use IRC for most of my chat needs. But then, there is private instant messaging. While IRC can solve this with queries and DCC chats, the protocol just isn't meant to work too well on intermittent connections, such as a mobile device, where you can often walk around places with low signal. I used MSN for a while, but didn't like it. The concept was awesome, but I think Microsoft didn't get the implementation quite right. When they started adding all that eye candy, and my buddies started flooding me with custom icons and buzzing my screen to it's knees, I shut my account and told folks that missed me to just email or call me. Much whining happened, I got called many weird things for not using MSN, but folks eventually got over it. Next, Google Talk came along, and seemed to be a lot better than MSN ever was. The protocol was open, so I could use whatever client I felt a fancy for. With the advent of smart phones, I just got myself a gtalk client on the phone, and have had a really decent integrated mostly-universal IM solution. Over the last few months, all Google services have been feeling flaky. IMs will often arrive anywhere between twenty minutes and one hour after being sent, clients will randomly disconnect, client priorities seem to work sometimes, and sometimes just a random device of those connected will get an IM. I think the time has come to look for greener grass. The Question It's rather hard to put what I'm looking for into precise words. I guess I just want something that is kind of like MSN/Gtalk, but that doesn't let me down when I need it. IRC is pretty much perfect, but the protocol just isn't designed to work well on mobile devices. Really, at this point I'm considering sticking to IRC for desktop messaging, and SMS/email on the phone, but I hope that in this day and age there is something better out there.

  • kill -9 doesn't work

    - by Daniel
    I have a server with 3 oracle instances on it, and the file system is nfs with netapp. After shutdown the databases, one process for each database doesn't quit for a long time. Each kill -i doesn't work. I tried to truss, pfile it, the command through error. And iostat shows there are lots of IO to the netapp server. So someone said the process was busy writing data to remote netapp server, and before the write complete, it won't quit. So what need to be done was just wait until all the IO was done. After wait for longer time (about 1.5 hours), the processes exit. So my question is: how can a process ignore the kill signal? As far as I know, if we kill -9, it will stop immediately. Do you encounter such situation kill -i doesn't kill the process right away?

  • Postfix not delivering email using Maildir

  • Can't detect wireless networks, running ubuntu 9.10 on eeepc 1000he

    - by David Brown
    Hi, I am running Ubuntu 9.10 on an ASUS eeepc 1000HE, and my wireless card, RaLink RT 2860, is failing to recognize any wireless networks. It was working fine this morning, until I accidentally hit Fn F2, disabling the wireless card. I hit Fn F2 again to reenable it, but it no longer will detect any wireless networks (and other computers in the household do recognize them). Any help at all will be greatly appreciated! I googled quite a bit and talked to a human about this but could not fix it. We tried dhclient ra0, which returned There is already a pid file /var/run/dhclient.pid with pid 2438 killed old client process, removed PID file Internet Systems Consortium DHCP Client V3.1.2 Copyright 2004-2008 Internet Systems Consortium.

  • Ubuntu Newbie Needs Assistance!!

    - by Steve Greene
    New Ubuntu User Needs Help!- version 9.10 does not communicate with laptop Hello folks, Several days ago, I installed Ubuntu 9.10 onto my Acer Aspire 3100 laptop, running it alongside Widows Vista as a dual-bootable system. Creation of the Ubuntu boot CD went fine, and the installation onto my hard drive was flawless. Ubuntu opens and behaves as I would expect, except for one little problem. For reasons unknown to me, Ubuntu is not communicating with my laptop's networking hardware, and I have no internet connectivity, even when sitting directly under the wireless router at the local library (literally), which puts out a wickedly-fast signal that my Windows Vista OS auto-detects and immediately connects to. Up in the right side of the Ubuntu desktop, I click on the network icon and it does not show a wireless connection at all, even though I am only a few feet from the router. At home, where I use a dialup modem, I also see no means of getting online. My modem is an HDAUDIO Soft Data Fax Modem with Smart CP,manufactured by CXT (Conexant Systems Inc., file version 4.0.13.0, and the driver version is 7.58.0.0). I desparately wish to convert to Ubuntu. I used Mac for ten years, and then Windows for ten years. Now, after 20 years, I want to live out my days as an open-source Ubuntu fanatic. I am ready to give the old status quo the boot! I am an advanced computer user, but I am not a programmer. I seek a solution that is user-friendly for normal people, something equivalent to a driver that I can easily install or activate that will allow Ubuntu to see my hardware and get me connected. Can anyone help me over this hopefully-little glitch so that I can move on in total Ubuntu bliss? My processor is a Mobile AMD Sempron Processor 3500+ at 1.80 GHz, 1.50 GB RAM, and a 32-bit Operating System. I am running Windows Vista Home Basic, Service Pack 2. My current email is [email protected] if you have a workable solution that does not require programmer status to implement. Surely this must be a simple fix that I simply am overlooking, but being the new guy on the block, I have yet to be enlightened. Thanks for your help in coming up to speed!! Steve Wanna' be Ubuntu Fanatic "If you're not living on the edge, you're taking up too much space."

  • shell script to start multiple Java programs from a directory at boot

    - by zcourts
    I'm not sure if this is the best approach to this, It's my first time doing all of this (including writing shell scripts). OS: Centos My problem: I want to start multiple shell scripts at boot. One of the shell scripts is to start my own services and 3 others are for third party services. The shell script to start my own services will be looking for jar files. I currently have two services (will change), written in Java. All services are named under convention prefix-service-servicename What I've done: I created the following directory structure /home/username/scripts init.sh boot/ boot/startthirdprtyservice1.sh boot/startthirdprtyservice2.sh boot/startthirdprtyservice3.sh boot/startmyservices.sh /home/username/services prefix-lib-libraryname.jar prefix-lib-libraryname.jar prefix-service-servicename.jar prefix-service-servicename.jar prefix-service-servicename.jar In init.sh I have the following: #!/bin/sh #This scripts run all executable scripts in the boot directory at boot #done by adding this script to the file /etc/rc.d/rc.local #nohup #run-parts /home/username/scripts/boot/* #for each file in the boot dir... # ignore the HUP (hangup) signal for s in ./boot/*;do if [ -x $s ]; then echo "Starting $s" nohup $s & fi done echo "Done starting bootup scripts " echo "\n" In the script boot/startmyservices.sh I have #!/bin/sh fnmatch () { case "$2" in $1) return 0 ;; esac ; return 1 ; } ##sub strin to match for SUBSTRING="prefix-service" for s in /home/username/services/*;do if [ -x $s ]; then #match service in the filename , i.e. only services are started if fnmatch "$SUBSTRING" "$s" ; then echo "Starting $s " nohup $s & fi fi done echo "Done starting Services" echo "\n" Finally: Usually you can stick a program in /etc/rc.d/rc.local for it to be run at boot but I don't think this works in this case, or rather I don't know what to put in there I've just learnt how to do this by reading up a bit so I'm not sure its particularly the best thing to do so any advice is appreciated. When I run init.sh nohup.out contains Starting the thirdparty daemon... thirdparty started... .... but nothing from myservices.sh and my Java services aren't running I'm not sure where to start debugging or what could be going wrong. Edit Found some issues and got it to work, used -x instead of -n to check if the string is none zero, needed the sub string check to also be if [[ $s = $SUBSTRING ]] ; then and this last one was just stupid, missing java -jar in front of $s Still unsure of how to get init.sh to run at boot though

  • Ubuntu Lucid: Erratic screen behaviour after boot

    - by fgysin
    In short: about 50% of the time I have a screwed up monitor setup after reboot. About 50% it is totally correct. Now the longer version: I updated my machine from 9.04 to 10.04 (via 9.10). At first I run into some monitor problems (I have a 3-monitor setup) because of the known bug in the new xserver driver for xinerama. This messes up behaviour if the mouse goes either left or above the screen number 0, i.e. I had to make my left-most monitor screen 0. Everything worked out fine finally, I got my 3-monitor setup back with xinerama enabled to get one big desktop streched over 3 screens. Now the fun part: Every time I start up my machine only one of the 3 monitors gets a signal and is woken up: it only recognizes the left-most monitor (screen 0) and crams all the desktop stuff into this one screen. If I go into nvidia settings I only see one physical device although all 3 are connected and have power. When I look into the xorg.conf I can still see my old setup with 3 devices, 3 screens, xinerama active etc... But I was totally unable to get 3 montitors to work. (I tried unplugging monitors, reconfiguring whole nvidia setup, ...) But it gets even better: When I restart my machine (i.e. choose the restart option from the Ubuntu menu) it shuts down and tries to restart. The restart then gets stuck after showing the Ubuntu splash screen with the 'loading bar' (the moving dots thingy) and I am forced to kill the machine by cutting power. But after the power cut the machine boots up normally and suddenly I get my 3 monitor setup back up working. That is until the next time I shut down and start up, where it all starts over again and I only have one monitor... (see above) I really have a hard time seeing where the error is. It must be that the restart boot somehow differs from the 'normal' boot. But the fact that it gets stuck and I need to cut power which then basically triggers a 'normal' boot does not really support this theory... My setup (please tell me if you need further info): 3 monitors as 3 screens as one desktop (with xinerama) 2 nvidia cards where screen 0 and 1 are on card 0 and screen 2 is on card 1 Ubuntu 10.04 Lucid Lynx (updated from 9.10, 9.04, ....) I would appreciate every idea on the subject, at the moment I really don't have any clue what to do...

  • Has the hardware in my modem gone bad?

    - by Tyler Scott
    I contacted CenturyLink about my modem recently and received useless and unrelated information. The problem seems to be that the modem will no longer save settings, the web interface is unusable except in internet explorer for some reason, and the modem keeps resetting. CenturyLink claimed it had to do with signal strength but I checked and it is currently between good and outstanding according to this. All of the lights remain green even when it starts acting up and I lose internet and shortly before it crashes and reboots. Does anyone have any idea what is going on or what I can do to fix it? (Asking CenturyLink again is obviously not going to help.) Update 1: Accessing the syslog from the web interface causes a crash. After it reboots, the log looks like as follows: 01/01/1970 12:01:29 AM Ethernet Ethernet client connected ,ip(192.168.0.2), mac(1c:6f:65:4c:6d:3b) 01/01/1970 12:01:38 AM Wireless 802.11 client connected ,ip(192.168.0.18), mac(d0:df:c7:c2:73:ca) 01/01/1970 12:01:41 AM System Event Line 0: VDSL2 link up, Bearer 0, us=20128, ds=40127 01/01/1970 12:01:43 AM dhcp6s[2028] dhcp6_ctl_authinit: failed to open /etc/dhcp6sctlkey: No such file or directory 01/01/1970 12:01:50 AM dhcp6s[2469] dhcp6_ctl_authinit: failed to open /etc/dhcp6sctlkey: No such file or directory 01/01/1970 12:01:52 AM radvd[2306] poll error: Interrupted system call 01/01/1970 12:01:56 AM PPP Link PPP server detected. 01/01/1970 12:01:56 AM PPP Link PPP session established. 01/01/1970 12:01:56 AM PPP Link PPP LCP UP. 01/01/1970 12:01:56 AM System Event Received valid IP address from server.

  • Hylafax / Capi4hylafax: faxgetty does not recognize number of lines

    - by Wrikken
    We've got a T.30 card, 30 working lines on it, but for some reason, if I add more then 30 faxes in the queue at any time (and we're busy enough at peak times that this happens a lot), faxgetty sends faxes to non-existent lines and they appear in the error queue as a 'busy' signal on the line, which results in a lot of failed faxes because the counter of max 3 tries increases rapidly. This is using faxgetty (USE_FAXGETTY="y" in /etc/default/hylafax). I've inherited this thing, so I'm not entirely sure how faxgetty is supposed to know the number of lines. However, if I alter the script to faxmodem (USE_FAXGETTY="n" in /etc/default/hylafax and manually enabling 30 modems), this behavior goes away (new faxes 'wait' for a line to be available before trying to send, so each try / fail is a valid one on a working line, majorly descreasing the amount of failed faxes. However, when researching this almost anyone talks about faxgetty being the preferred, more robust, method, and on top of that for some unexplained reason all FIFO's disappeared for some reason after several errorless hours with faxmodem, forcing a hylafax restart using faxgetty until we figured out why this faxmodem solution failed (which is another question, and somewhat out of scope here). Environment: Debian 2.6.26-2-amd64 capi4hylafax 1:01.03.00.99.svn.300-12 hylafax-client 2:4.4.4-10.1 hylafax-server 2:4.4.4-10.1 Config --hfaxd.conf-- LogFacility: daemon ServerTracing: 0x1ff --hyla.conf-- Host: localhost Verbose: No VRes: 196 TimeZone: local DialRules: "/etc/hylafax/dialrules.europe" --/etc/hylafax/config -- InternationalPrefix: 00 LongDistancePrefix: 0 AreaCode: 99999 CountryCode: 31 DialStringRules: "etc/dialrules.europe" ModemGroup: any:faxCAPI SendFaxCmd: "/usr/bin/wrapc2faxsend" --/etc/hylafax/config.faxCAPI -- SpoolDir: /var/spool/hylafax FaxRcvdCmd: /var/spool/hylafax/bin/faxrcvd PollRcvdCmd: /var/spool/hylafax/bin/pollrcvd FaxReceiveUser: uucp FaxReceiveGroup: dialout LogFile: /var/spool/hylafax/log/capi4hylafax #no, checking this log did not yield anything interesting LogTraceLevel: 4 LogFileMode: 0600 ModemGroup: any:faxCAPI #repeats of faxCAPI2 = faxCAPI30, with of course another devicename/local ident: { HylafaxDeviceName: faxCAPI RecvFileMode: 0600 FAXNumber: ****redacted**** LocalIdentifier: ****some-ident-per-device*** MaxConcurrentRecvs: 0 OutgoingController: 1 OutgoingMSN: SuppressMSN: 0 NumberPrefix: NumberPlusReplacer: "00" UseISDNFaxService: 0 RingingDuration: 0 { Controller: 1 AcceptSpeech: 0 UseDDI: 0 DDIOffset: DDILength: 0 IncomingDDIs: IncomingMSNs: AcceptGlobalCall: 1 } } So in short: How does faxgetty determine the number of lines available? (the man page isn't terribly revealing, and I can't find an appropriate setting in hylafax-config. And how can I get a capi4hylafax/hylafax setup which queues more faxes then lines are available correctly without immediately incrementing the fail count? We will not be receiving any faxes on this machine b.t.w. As I said, I've inherited this thing, so if there are important configuration options I'm not including, please let me know.

  • Converting an EC2 AMI to vmdk image

    - by Reed G. Law
    I've come quite close to getting Amazon Linux to boot inside VirtualBox, thanks to this answer and these websites. A quick overview of the steps I've taken: Launch EC2 instance with Amazon Linux 2011.09 64-bit AMI dd the contents of the EBS volume over ssh to a local image file. Mount the image file as a loopback device and then to a local mount point. Create a new empty disk image file, partition with an offset for a bootloader, and create an ext4 filesystem. Mount the new image's partition and copy everything from the EC2 image. Install grub (using Ubuntu's grub-legacy-ec2 package, not grub2). Convert the image file to vmdk using qemu-img. Create a new VirtualBox VM with the vmdk. Now the VM boots, grub loads, and the kernel is found. But it fails when it tries to mount the root device: dracut Warning: No root device "block:/dev/xvda1" found dracut Warning: Boot has failed. To debug this issue add "rdshell" to the kernel command line. dracut Warning: Signal caught! dracut Warning: Boot has failed. To debug this issue add "rdshell" to the kernel command line. Kernel panic - not syncing: Attempted to kill init! Pid: 1, comm: init Not tainted 2.6.35.14-107.1.39.amzn1.x86_64 #1 I have tried changing /boot/grub/menu.lst to find the root device by label and UUID, but nothing works. I'm guessing the xen kernel is not compatible with VirtualBox. The reasoning behind all this effort is to make a Vagrant box that is as close to possible as the production enviroment, so deploys can be tested locally. I know it's cheap to do test runs on EC2, but poor connectivity often ruins the experience. Plus it would be really nice to have a virtual machine with the production environment so that co-workers don't have to install everything under the sun just to get up and running with app development. If I were to try running a different kernel, what kernel could I get to be as close as possible to Amazon Linux 2011.09?

  • Why is my Linux box dropping network connection? [closed]

    - by Robo
    I have a Debian server in the form of a Raspberry Pi running Raspian. It has a USB Wi-Fi connection. Sometimes it would not respond when I SSH to it, and would require a reboot. I found something in syslog that may indicate what the problem is, can someone help with what this means?

  • Wireless 802.11x Disconnects

    - by BillP3rd
    I've looked at (and read) all of the similar questions and none of them get exactly to the issue I'm having at home. I have an 802.11g access point (two, actually, with different SSIDs and on different channels). One is an Airlink AR525W. The other is a Linksys WRT54G v.2. The issue is that at random times, my laptop will lose its wireless connection. This occurs regardless of which access point I'm connected to. When I lose the connection, the affected AP no longer appears in the list of available APs. Also, it doesn't have anything to do with walls or distance. It can happen within 30' and when my laptop is literally within line-of-sight. When it loses the signal, it can take from 10 to 30 minutes to reconnect and it always will without intervention. I've done all the “standard” things to troubleshoot the problem and it has improved. For example, I surveyed other access points in my vicinity and have selected a different channel for each of my APs that no one else nearby is using. Both APs are configured WPA2/AES. I'm down to wondering [Note: This is not a shopping question. I'm not buying a new AP] if the fact that I didn't drop two bills on my APs and instead opted for more modest solutions has anything to do with it? I've oft wondered why anyone would go for the high-end AP when they didn't have to. Also, I am aware of DD-WRT and have chosen not to go there because only one of my APs is supported. Oh, and one final thing. It an HP x64 laptop running Windows 7 Ultimate. The wireless interface is an Atheros AR9285 802.11b/g/n WiFi Adapter. All the latest drivers and service packs have been applied. It did the same thing with my old laptop (a Lenovo) so I don't the problem is in the laptop. It's really annoying when this happens and suggestions of things I haven't thought of or may have overlooked (No, really. As unlikely as it is, I admit that I may have overlooked something :-)) are appreciated.

  • Wake On Lan only works on first boot, not sequent ones

    - by sp3ctum
    I have converted my old Dell Latitude D410 laptop to a server for tinkering. It is running an updated Debian Squeeze (6) with a Xen enabled kernel (I want to toy with virtual machines later on). I am running it 'headless' via an ethernet connection. I am struggling to enable Wake On Lan for the box. I have enabled the setting in the BIOS, and it works nicely, but only for the first time after the power cord is plugged in. Here is my test: Plug in power cord, don't boot yet Send magic Wake On Lan packet from test machine (Ubuntu) using the wakeonlan program Server expected to start (does every time) Once server has booted, log in via ssh and shut it down via the operating system After shutdown, wake server up via WOL again (fails every time) Some observations: Right after step 1 I can see the integrated NIC has a light on. I deduce this means the NIC gets adequate power and that the ethernet cable is connected to my switch. This light is not on after step 4 (the shutdown stage). The light becomes back on after I disconnect and reconnect the power cord, after which WOL works as well. After step 4 I can verify that wake on lan is enabled via the ethtool program (repeatable each time) This blog post suggested the problem may lay in the fact the motherboard might not be giving adequate power to the NIC after shutdown, so I copied an acpitool script that supposedly should signal the system to give the needed power to the card when shut down. Obviously it did not fix my issue. I have included the relevant power settings in the paste below. I have tried different combinations of parameters of shutdown (the program) options, as well as the poweroff program. I even tried "telinit 0", which I figured would do the most direct boot via software. If I keep the laptop's power button pressed down and do a hard boot this way, the light on the ethernet port stays lit and a WOL is possible. I copied a bunch of hopefully useful information in this paste I have tried this with the laptop battery connected and without it. I get the same result. Promptly pressing the power button causes the system to shut down with the message "The system is going down for system halt NOW!", and WOL is still unsuccessful.

  • PC monitors shut off and system hangs while playing 3D games, but sound continues - Diagnosis?

    - by Jon Schneider
    Two days ago, I started running into a problem with my Windows PC: The PC's two connected monitors simultaneously lose signal and go black (as though the PC had been powered off). The keyboard's Numlock, Capslock, and Scroll Lights will become "stuck" in their current positions, as though the PC is hung. (For example, the Numlock light on the keyboard remains lit regardless of me pressing the Numlock key repeatedly.) No keyboard input does anything. (Ctrl+Alt+Del, Ctrl+Shift+Esc, Ctrl+C, etc.) However -- Whatever sound/music the PC was playing continues to play, and the PC's fans continue running, so the PC hasn't powered itself off or rebooted itself. Opening up the case, the graphics card is pretty hot to the touch. I had this happen 3 times in one evening. In all cases, I was playing a game with 3D graphics when the problem occurred (Torchlight, Minecraft, Magic: The Gathering 2012, Avadon: The Black Fortress demo). I have yet to have the problem happen when I'm not playing a game. This system has been running stable for about 2.5 years prior to this. I didn't make any changes to the system prior to the problem starting to occur. System specs: OS: Windows 7 64-bit Processor: Intel Core 2 Duo E7200 Wolfdale 2.53GHz Video Card: XFX GeForce 9800 GT 512 MB Motherboard: Foxconn P45A-S LGA 775 Intel ATX RAM: Corsair 4 GB (2x 2GB) DDR2-800 (PC2 6400) Full specs: New PC 2008 Troubleshooting tried so far (the problem occurred again after taking each of these steps, one at a time): Updated the video drivers with the latest drivers from NVidia's site. Opened up the case and cleaned out the video card and processor fans (both were pretty dirty). Installed and ran temperature monitor software. The processor idles at about 50 degrees C, and goes up to about 63 degrees C while playing a game (seems on the warm side, but not excessively so?). The software wasn't able to report the temperature of the GPU -- not sure this particular GPU supports software temperature readout? My initial diagnosis is that maybe the GPU is on its last legs (given that it seems to be running pretty hot, and the problem only occurs while playing 3D games). Does this seem likely? Or is it likely that this problem is caused by the processor, RAM, or motherboard? Or could this be a software issue of some kind? Thanks for any advice!

  • Sendmail smtp-auth issues

    - by SlackO
    I'm running into a problem with Sendmail trying to implement SMTP- auth. I"m running 8.14.5 and have saslauthd running under FreeBSD 7.0-R. I don't believe I have starttls enabled (but I also compiled a version with it and have been testing it too - same problem) - just looking for basic auth, but am wondering if my configuration is not compatible with modern mail clients? I don't think I have any certs set up. It seems an older version of Microsoft Outlook Express works fine with SMTP-auth with no problems, but Outlook 2010 won't work, and neither will Eudora (basic settings to not use encryption and use same uid/pw as pop3 account name) When trying to send mail the server reports: "550 571 Relaying Denied. Proper authentication required." Is there some config that I am missing? Why does it work with Outlook Express but not other e-mail clients? my site.config.m4 has: APPENDDEF(confENVDEF',-DSASL=2') APPENDDEF(conf_sendmail_LIBS',-lsasl2') dnl APPENDDEF(confLIBDIRS',-L/usr/local/lib/sasl2') APPENDDEF(confLIBDIRS',-L/usr/local/lib') APPENDDEF(confINCDIRS',-I/usr/local/include') My sendmail.mc has: define(ConfAUTH_OPTIONS',A') TRUST_AUTH_MECH(LOGIN PLAIN')dnl define(ConfAUTH_MECHANISMS',`LOGIN PLAIN')dnl My /usr/local/lib/sasl2/Sendmail.conf has: pwcheck_method: saslauthd When I restart sendmail this shows up in the logs: Jun 16 12:36:24 x sm-mta[79090]: restarting /usr/sbin/sendmail due to signal Jun 16 12:36:24 x sm-mta[81145]: starting daemon (8.14.5): SMTP+queueing@00:30:00 Jun 16 12:36:24 x sm-mta[81147]: STARTTLS=client, relay=mxgw1.mail.nationalnet.com., version=TLSv1/SSLv3, verify=FAIL, cipher=DHE-RSA-AES256-SHA, bits=256/256 Jun 16 12:36:24 x sm-mta[81148]: STARTTLS=client, relay=mxgw1.mail.nationalnet.com., version=TLSv1/SSLv3, verify=FAIL, cipher=DHE-RSA-AES256-SHA, bits=256/256 testing on the cmd line: telnet localhost 587 Trying 127.0.0.1...

  • phpMyAdmin causes php-fpm worker to restart (502 Bad Gateway)

  • Encoding multiple video streams with a single avconv invocation

    - by automatthias
    I played with avconv on Ubuntu and I'm now able to e.g. record the desktop with sound from a soundcard. One thing I wanted to do was recording two video inputs at the same time, for instance the desktop and from the webcam. I thought about doing something like this: avconv \ -f alsa \ -i default \ -acodec flac \ -f video4linux2 \ -r 6 \ -i /dev/video0 \ -f x11grab \ -i :0.0 \ out.mkv My thinking was that if you define multiple video inputs, and the .mkv format can handle multiple video streams, avconv will encode 2 video streams and 1 audio stream into one file. But this isn't what happens: avconv version 0.8.4-6:0.8.4-0ubuntu0.12.10.1, Copyright (c) 2000-2012 the Libav developers built on Nov 6 2012 16:51:11 with gcc 4.7.2 [alsa @ 0x1091bc0] capture with some ALSA plugins, especially dsnoop, may hang.

  • Ubuntu Lucid: Erratic screen behaviour after boot

    - by fgysin
    In short: about 50% of the time I have a screwed up monitor setup after reboot. About 50% it is totally correct. Now the longer version: I updated my machine from 9.04 to 10.04 (via 9.10). At first I run into some monitor problems (I have a 3-monitor setup) because of the known bug in the new xserver driver for xinerama. This messes up behaviour if the mouse goes either left or above the screen number 0, i.e. I had to make my left-most monitor screen 0. Everything worked out fine finally, I got my 3-monitor setup back with xinerama enabled to get one big desktop streched over 3 screens. Now the fun part: Every time I start up my machine only one of the 3 monitors gets a signal and is woken up: it only recognizes the left-most monitor (screen 0) and crams all the desktop stuff into this one screen. If I go into nvidia settings I only see one physical device although all 3 are connected and have power. When I look into the xorg.conf I can still see my old setup with 3 devices, 3 screens, xinerama active etc... But I was totally unable to get 3 montitors to work. (I tried unplugging monitors, reconfiguring whole nvidia setup, ...) But it gets even better: When I restart my machine (i.e. choose the restart option from the Ubuntu menu) it shuts down and tries to restart. The restart then gets stuck after showing the Ubuntu splash screen with the 'loading bar' (the moving dots thingy) and I am forced to kill the machine by cutting power. But after the power cut the machine boots up normally and suddenly I get my 3 monitor setup back up working. That is until the next time I shut down and start up, where it all starts over again and I only have one monitor... (see above) I really have a hard time seeing where the error is. It must be that the restart boot somehow differs from the 'normal' boot. But the fact that it gets stuck and I need to cut power which then basically triggers a 'normal' boot does not really support this theory... My setup (please tell me if you need further info): 3 monitors as 3 screens as one desktop (with xinerama) 2 nvidia cards where screen 0 and 1 are on card 0 and screen 2 is on card 1 Ubuntu 10.04 Lucid Lynx (updated from 9.10, 9.04, ....) I would appreciate every idea on the subject, at the moment I really don't have any clue what to do...
