  • Using Toshiba 22EL833 as PC display with GTX8800

    - by Oleg V. Volkov
    I had another Toshiba TV - 19SL738 - connected to this same PC and video card (GTX 8800) through DVI<-HDMI (DVI on PC side, HDMI on TV) before, that was working perfectly at it's native resolution 1360x768. Some time ago I had to change to 22EL833 and immediately faced problem with Windows 7 control panel and NVIDIA control panel both reporting native resolution for new TV as 1080i, 1920x1280, despite TV documentation saying that it have same 1360x768 as previous one. Practical tests confirmed that true native resolution is indeed 1360x768, because plugging in through DVI<-VGA and setting custom resolution through NVIDIA panel shown clear colors and crisp image, while setting anything different with either DVI<-VGA or DVI<-HDMI produced horribly distorted or squished images, with almost unreadable slim lines (as in letters, for example). Now, my problem is that there's no drivers for this TV and I'm unable to get good image while connecting it through DVI<-HDMI directly. The best I've achieved is editing EDID/driver manually, to persuade system that native resolution should be 1360x768, and while image became mostly clear, colors turned to some strange washed out effect, with pools of pure yellow, cyan and magenta there and there filling place of other colors. Gradients also became noticeably stripped as well. Somehow it looks like dithering gone bad and makes me suspect that image is still down/upscaled several times internally somewhere along the line. How can I connect this TV to DVI output of my video card to get best possible clear image, correct colors and correct native resolution?

  • ssh refuses to authenticate keys

    - by MixturaDementiae
    So I am setting up a connection between my machine [fedora 17] and a virtual machine running in Virtual Box in which is running CentOS 5. I have installed openssh from the repositories on CentOS, and I have configured everything as it follows: Protocol 2 HostKey /etc/ssh/ssh_host_rsa_key HostKey /etc/ssh/ssh_host_dsa_key SyslogFacility AUTHPRIV PermitRootLogin yes RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile /home/pigreco/.ssh/authorized_keys PasswordAuthentication no ChallengeResponseAuthentication yes GSSAPIAuthentication yes GSSAPICleanupCredentials yes UsePAM yes AcceptEnv LANG LC_CTYPE LC_NUMERIC LC_TIME LC_COLLATE LC_MONETARY LC_MESSAGES AcceptEnv LC_PAPER LC_NAME LC_ADDRESS LC_TELEPHONE LC_MEASUREMENT AcceptEnv LC_IDENTIFICATION LC_ALL LANGUAGE AcceptEnv XMODIFIERS X11Forwarding yes Subsystem sftp /usr/libexec/openssh/sftp-server this is the configuration file sshd_config on the server i.e. on the CentOS. Moreover I have created a public/private key pair as usual on the .ssh/ folder in my home directory in my OS, i.e. Fedora, and then I've copied with scp the id_rsa.pub to the server and then I have appended its content to the file .ssh/authorized_keys on the server machine.

  • Getting an alert when my oracle database goes up or down

    - by CodeSlave
    How can I get an e-mail alert when my oracle database comes up or down? I have a database that I need to know when it goes down (it would be nice to know if it has come back up), preferably from a remote machine. Conceivably I could hack together something that TNSPings my DB and e-mails me when that changes, but I'm hoping there's a free package out there. Something that would run on windows. Any strong recommendations?

  • Why does hiberfil.sys come back from the dead on Windows 7?

    - by Corey White
    I have Windows 7 running on a small (40GB) partition, with 4GB ram. This means that the hiberfil.sys file created by Hibernate takes up a significant portion of the available diskspace. I would like to remove it. I am aware that I can disable Hibernate and remove hiberfil.sys by entering powercfg -h off in an elevated command prompt. This works -- the file is immediately removed, and after doing so, the HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\HibernateEnabled key is (correctly) set to 0. However, the next time I reboot the PC, hiberfil.sys returns from the dead, Hibernate is reenabled, and that registry key has returned to 1. I'm pretty much at my wits' end with this. Almost everything I can find online related to removing the hiberfil.sys file simply suggests using powercfg to turn off hibernation, and that appears to work for just about everyone. But it just keeps coming back for me! (Like a vampire, sucking up my disk space.) I did find one other thread from someone who seems to have had the same issue, but none of the suggestions there worked for the original poster (or for me). Still, I have tried everything listed there, including: Disabling hybrid sleep Disabling Hibernate through the command prompt, through the Power Options GUI, and through both (in both orders) Manually changing the HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\HibernateEnabled key Pretty much everything else I can think of! I do want to reiterate that I have no problem removing the file -- that works great. It just comes back after every reboot. I'm about ready to throw in the towel and just run a script on login to disable Hibernate each time, even though that seems like a crazily hacky "solution" . . . but I was hoping someone here could suggest something else, first. Thanks!

  • Registry remotley hacked win 7 need help tracking the perp

    - by user577229
    I was writing some .VBS code at thhe office that would allow certain file extensions to be downloaded without a warning dialog on a w7x32 system. The system I was writing this on is in a lab on a segmented subnet. All web access is via a proxy server. The only means of accessing my machine is via the internet or from within the labs MSFT AD domain. While writing and testing my code I found a message of sorts. Upon refresing the registry to verify my code changed a dword, instead the message HELLO was written and visible in regedit where the dword value wass called for. I took a screen shot and proceeded to edit my code. This same weird behavior occurred last time I was writing registry code except on another internal server. I understand that remote registry access exists for windows systems. I will block this immediately once I return to the office. What I want to know is, can I trace who made this connection? How would I do this? I suspect the cause of this is the cause of other "odd" behaviors I'm experiencing at work such as losing control of my input director master control for over an hour and unchanged code that all of a sudden fails for no logical region. These failures occur at funny times, whenver I'm about to give a demonstration of my test code. I know this sounds crazy however knowledge of the registry component makes this believable. Once the registry can be accessed, the entire system is compromised. Any help or sanity checking is appreciated.

  • What user is the script run as after Carbon Copy Cloner ends scheduled task?

    - by Paolo
    On Mac OS X I keep data on a local server mirrored with the same data on a remote server with a scheduled backup task done with Carbon Copy Cloner. After the backup is done a bash script is run as specified in the scheduled task options of CCC. Is the script run as root? Or differently and more generally: as my script writes to a log file, what command should I put on my script to see on the log if the script is running as root or something else?

  • Using wget to save sequential files as well as renaming the file extension

    - by Ian
    I run a cron job that requests a snapshot from a remote webcam at a local address: wget http://user:[email protected]/snapshot.cgi This creates the files snapshot.cgi, snapshot.cgi.1, snapshot.cgi.2, each time it's run. My desired result would be for the file to be named similar to file.1.jpg, file.2.jpg. Basically, sequentially or date/time named files with the correct file extension instead of .cgi. Any ideas?

  • Is there anyway way to speed up Exchange 2007's Load Generator tool?

    - by JohnM
    I'm running Load Generator to test our new deployment before going live and the initialization process has been running for two days and is only at 25% for ~58000 user test. Does anyone know of a way to speed up this process? Surely it shouldn't take this long. Currently, I've got it running with one master and two remote servers and they aren't peaking out on CPU or Network utilization. Any help you could provide would be greatly appreciated.

  • Weird mouse behaviour. Debian wheezy

    - by DevNoob
    When I move my mouse slowly over the desktop the pointer jumps often a few pixels (one or two) in the opposite direction of which I move my mouse. Horribly when trying to set the cursor around some semicolons in eclipse. I guess this is the result of a wrong set resolution of it. I suppose this is because the mouse was set initially really fast and even if I do xset 1/2 3, the mouse is just to fast and unprecise for me. It aready tried to configure the xorg.conf like this: Section "InputDevice" Identifier "Configured Mouse" Driver "mouse" Option "Device" "/dev/mouse" Option "Protocol" "Auto" Option "Name" "Logitech G3" Option "Resolution" "2000" EndSection But with no effect. Maybe because there is no /dev/mouse. This ist the content of dev. Maybe you can tell me which one is the mouse. autofs block bsg btrfs-control bus cdrom cdrw char console core cpu cpu_dma_latency disk dvd dvdrw fd fd0 full fuse fw0 hidraw0 hidraw1 hpet input kmsg log loop0 loop1 loop2 loop3 loop4 loop5 loop6 loop7 loop-control MAKEDEV mapper mcelog mem net network_latency network_throughput null nvidia0 nvidiactl oldmem port ppp printer psaux ptmx pts random rfkill root rtc rtc0 sda sda1 sda2 sda3 sda5 sda6 sda7 sda8 sdb sdb1 sg0 sg1 sg2 shm snapshot snd sndstat sr0 stderr stdin stdout tty tty0 tty1 tty10 tty11 tty12 tty13 tty14 tty15 tty16 tty17 tty18 tty19 tty2 tty20 tty21 tty22 tty23 tty24 tty25 tty26 tty27 tty28 tty29 tty3 tty30 tty31 tty32 tty33 tty34 tty35 tty36 tty37 tty38 tty39 tty4 tty40 tty41 tty42 tty43 tty44 tty45 tty46 tty47 tty48 tty49 tty5 tty50 tty51 tty52 tty53 tty54 tty55 tty56 tty57 tty58 tty59 tty6 tty60 tty61 tty62 tty63 tty7 tty8 tty9 ttyS0 ttyS1 ttyS2 ttyS3 uinput urandom usb vcs vcs1 vcs2 vcs3 vcs4 vcs5 vcs6 vcs7 vcsa vcsa1 vcsa2 vcsa3 vcsa4 vcsa5 vcsa6 vcsa7 vga_arbiter vmci vmmon vmnet0 vmnet1 vmnet8 vsock watchdog xconsole zero So my question is: How do I setup my mouse correctly in Debian wheezy?

  • Upgrade from Etch to Lenny, server no longer reboots

    - by Jack
    Hi, I just upgraded my (remote) webserver to Lenny from Etch. and no real issue occurs except that I cannot reboot that server. (I can only start in a rescue mode) I recall that a MBR change performed and I am wondering if that could be the reason for this failure. Would someone know how I can revert this MBR change ? I had switched back to my previous linux kernel, still cannot reboot. I would appreciate your help. thanks Jack

    I have a bad Internet connection, it disconnects frequently and on reconnect, I'm assigned a different IP address by the ISP. The problem is that I connect to a remote VPS (Ubuntu), and when Internet connection is disrupted n reconnected, I can no longer do anything on the terminal. I have to restart the terminal and re-initiate the connection. Is there a way I can have persistent connection with server.

  • How should I set up protection for the database against sql injection when all the php scripts are flawed?

    - by Tchalvak
    I've inherited a php web app that is very insecure, with a history of sql injection. I can't fix the scripts immediately, I rather need them to be running to have the website running, and there are too many php scripts to deal with from the php end first. I do, however, have full control over the server and the software on the server, including full control over the mysql database and it's users. Let's estimate it at something like 300 scripts overall, 40 semi-private scripts, and 20 private/secure scripts. So my question is how best to go about securing the data, with the implicit assumption that sql injection from the php side (e.g. somewhere in that list of 300 scripts) is inevitable? My first-draft plan is to create multiple tiers of different permissioned users in the mysql database. In this way I can secure the data & scripts in most need of securing first ("private/secure" category), then the second tier of database tables & scripts ("semi-private"), and finally deal with the security of the rest of the php app overall (with the result of finally securing the database tables that essentially deal with "public" information, e.g. stuff that even just viewing the homepage requires). So, 3 database users (public, semi-private, and secure), with a different user connecting for each of three different groups of scripts (the secure scripts, the semi-private scripts, and the public scripts). In this way, I can prevent all access to "secure" from "public" or from "semi-private", and to "semi-private" from "public". Are there other alternatives that I should look into? If a tiered access system is the way to go, what approaches are best?

  • Ubuntu Pound Reverse Proxy Load Balancing Based off active server load?

    - by Andrew
    I have Pound installed on a loadbalancer. It seems to work okay, except that it randomly assigns the backend server to forward the request to. I've put 1 backend machine under so much load that it went into using swap, and I can't even ssh into it to test this scenareo. I would like the loadbalancer to realize that the machine is overloaded, and send it to a different backend machine. However it doesn't. I've read the man page and it seems like the directive "DynScale 1" is what would monitor this, but it still redirects to the overloaded server. I've also put in "HAport 22" to the backend figuring since I can't ssh in, neither could the loadbalancer and it would consider the backend server dead until it gets rid of the load and responds, but that didn't help either. If anyone could help with this, I'd appreciate it. My current config is below. ###################################################################### ## global options: User "www-data" Group "www-data" #RootJail "/chroot/pound" ## Logging: (goes to syslog by default) ## 0 no logging ## 1 normal ## 2 extended ## 3 Apache-style (common log format) LogLevel 3 ## check backend every X secs: Alive 5 DynScale 1 Client 1200 TimeOut 1500 # poundctl control socket Control "/var/run/pound/poundctl.socket" ###################################################################### ## listen, redirect and ... to: ## redirect all requests on port 80 to SSL ListenHTTP Address 192.168.1.XX Port 80 Service Redirect "https://xxx.com/" End End ListenHTTPS Address 192.168.1.XX Port 443 Cert "/files/www.xxx.com.pem" Service BackEnd Address 192.168.1.1 Port 80 HAport 22 End BackEnd Address 192.168.1.2 Port 80 HAport 22 End End End

  • Comcast SMC Port Forwarding Issue

    - by Zach Fedora
    I have a Comcast SMCD3G modem/router and I've been having issues getting the port to forward - When I check an online "open-port-checker" it says the port is forwarded/they can see the port on my IP. (1 Static IP is assigned to the modem) But when I try to access port 80 for example on a browser, it times out. Also when I try to remote desktop to the server (Windows Server 2008 R2) it doesn't work, yet canyouseeme.org says it is open. Any ideas as to what the problem could be?
