• 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?

• Modifier key bug with Adobe Design Standard CS4 (Mac OS 10.6.6)

  - by Andy

  When I launch the Adobe apps, they ask me if I want to delete the preferences file. I say 'no'. Then, when using the apps, none of the tools seem to work properly, eg in Illustrator, I can't move objects without it duplicating the object. Photoshop constantly displays the contextual menu icon that usually only appears when you hold down the control key. I can't do any work in them when this happens, so I am forced to log out and then back in. They work for a while and then this annoying bug happens again. I think it must be to do with the modifier keys (command option and control). I think Adobe's apps must think I'm permanently pressing the modifier keys down - the thing is, no other app on my machine has this problem! Does anyone else experience this? Or have a fix for it? Any suggestions much appreciated. Running: Mac OS X 10.6.6 on an iMac. Adobe CS4 Design standard installed.

• Writing an upstart file which allows the user to input username and password

  - by Robert Munteanu

  I'm trying to write an upstart file for OpenConnect. The task is pretty simple, but I'm stuck because I don't want to provide the username and password in a config file, but prompt the user to provide them each time. The upstart file, placed in /etc/init/openconnect.conf is exec /usr/sbin/openconnect --script=/etc/vpnc/vpnc-script my-gw.example.com However, when I execute start openconnect the process is backgrounded immediately and I get no chance to provide input. How can I make this upstart job ask the user for input?

• Starting to Burn CD and system momentarily freezes

  - by Josh Stodola

  Every time I burn a CD using Nero (or anything else) on my Windows XP machine, the entire system locks up for like 5 seconds. It happens when the burner starts making noise. Then when it comes back, it starts burning and does a great job of it. What is this lag and how can I stop it?

• 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!

• Recommendations on managing dot files for users using Puppet

  - by Beaming Mel-Bin

  Goal is to have a collection of dot files (.bashrc, .vimrc, etc.) in a central location. Once it's there, Puppet should push out the files to all managed servers. I initially was thinking of giving users FTP access where they could upload their dot files and then having an rsync cron job. However, it might not be the most elegant or robust solution. Wanted to see if anyone else had some recommendations.

• What Triggers a syncronization between Exchange 2007 Mail Store and Edge Servers?

  - by BillN

  We are using Exchange 2007 for our mail. In our configuration, we need to add an alias to each users mailbox. When we do, the Edge server, another Exchange 2007 box, will reject the alias with a User Unknown error until the next morning. I seem to recall that in Exchange 2003, you could force an update from the Management console, but I can not find a way in 2007. It is obvious that a sync job is scheduled to run each night, but I cannot find it.

• 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.

• 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?

• 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?

• 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

• Sending email with exim and external sender address

  i have following problem: i want to send emails with an rails webapp. i set up an exim server and when looking into the logs, the sending works, but the emails aren't sent really. i had the same problem with another isp. the sender address is hosted on another mailserver, other isp. i think the problem is, that sending doesn't work because the sener address isn't hosted on the same server. do you have any advice on this? the logs (exim) tell me the following: 2011-01-01 14:38:06 1PZ1eo-0000Ga-38 <= <> R=1PZ1eo-0000GY-1p U=Debian-exim P=local S=1778 2011-01-01 14:38:08 1PZ1eo-0000Ga-38 => [email protected] R=dnslookup T=remote_smtp H=mx1.emailsrvr.com [98.129.184.131] X=TLS1.0:RSA_AES_256_CBC_SHA1:32 DN="C=US,O=mx1.emailsrvr.com,OU=GT21850092,OU=See www.geotrust.com/resources/cps (c)08,OU=Domain Control Validated - QuickSSL(R),CN=mx1.emailsrvr.com" 2011-01-01 14:38:08 1PZ1eo-0000Ga-38 Completed [email protected] is the external sender-address! thank you!

  Hi, My mother has some serious issues using Windows (viruses, spywares, and so on) and I seriously think about setting up Ubuntu as a replacement. (That would ease my "job" as well) The only concern I have is, is there anything to edit .docx (or .xlsx, .pptx, ...) documents on Linux ? Last time I tried OpenOffice (was 3 years ago), it was only able to open "old" MS Office documents (.doc, .xls, ...). Thank you very much for your answers !

• Compiling PHP with cURL and SSL support on Redhat EC5

  - by Kevin Sedgley

  I don't even know where to begin to be honest. Trying to use an external API that requires SSL connections, I discover that SSL in needed on cURL, but this (apparently) requires PHP to be reinstalled and compiled with cURL / SSL support. Not really experienced with compiling PHP, and I'm not sure if our server even has make or build, the only luck I've had is with rpm's before. This really isn't in my job description. Any help most most welcome!

• Colorizing your terminal and shell environment?

  - by Stefan Lasiewski

  I spend most of my time working in Unix environments and using Terminal emulators. I try to use color on the commandline, because color makes the output more useful and intuitive. What are some good ways to add color to my terminal environment? What tricks do you do? What pitfals have you encountered? Unfortunately, support for color is wildly variable depending on terminal type, OS, TERM setting, utility, buggy implementations, etc. Here's what I do currently, after alot of experimentation: I tend to set 'TERM=xterm-color', which is supported on most hosts (but not all). I work on a number of different hosts, different OS versions, etc. I'm trying to keep things simple and generic, if possible. Many OSs set things like 'dircolors' and by default, and I don't want to modify this everywhere. So I try to stick with the defaults. Instead tweak my Terminal's color configuration. Use color for some unix commands (ls, grep, less, vim) and the Bash prompt. These commands seem to the standard "ANSI escape sequences" I've managed to find some settings which are widely supported, and which don't print gobbledygook characters in older environments (even FreeBSD4!) (For the most part). From my .bash_profile ### Color support # The Terminal application typically does 'export TERM=term=color' # Some terminal types will print Black, White & underlined with these settings. OS=`uname -s` case "$OS" in "SunOS" ) # Solaris9 ls doesn't allow color, so use special characters instead. LS_OPTS='-F' ;; "Linux" ) # GNU tools supports colors! See dircolors to customize colors export LS_OPTS='--color=auto' # Color support using 'less -R' alias less='less --RAW-CONTROL-CHARS' alias ls='ls ${LS_OPTS} export GREP_OPTIONS="--color=auto" ;; "Darwin"|"FreeBSD") # Most FreeBSD & Apple Darwin supports colors # LS_OPTS="-G" export CLICOLOR=true alias less='less --RAW-CONTROL-CHARS' export GREP_OPTIONS="--color=auto" ;; esac

• DNS: how to get local server to superimpose results over authoritative server?

  - by growse

  I've got a domain for which the DNS I control, and is hosted on the internet. I also have a NAT'd internal network (192.168.0.0/24) which has internet access, and which I also control. On this internal network, I also have a DNS resolver. DNS software on both is PowerDNS. What I want to be able to do is for the DNS resolver on the internal network to be able to add/change records of queries and results that come down from the authoritative server. For example, the authoritative server might have a single record for animal.example.com: animal.example.com. IN AAAA 2001:140:283::1 However, I'd like it so that when internal clients do a dns lookup for animal.example.com, they might get back the following: animal.example.com. IN AAAA 2001:140:283::1 animal.example.com. IN A 192.168.0.2 Obviously, I could set up the internal DNS server to pretend to be authoritative for example.com, but that would require a fair bit of effort to keep the main DNS server and the internal DNS server in sync for the records which are the same between both. If the internal DNS server could somehow be made a slave of the main DNS server, but also have the provision to add its own results in, that would be ideal. Is this possible?

• Requesting better explanation for expires headers

  - by syn4k

  I have successfully implemented expires headers however, for several days I have been stumped by one thing. This article: http://www.tipsandtricks-hq.com/how-to-add-far-future-expires-headers-to-your-wordpress-site-1533 states Keep in mind that when you use expires header the files are cached in the browser until it expires so do not use this on files that changes frequently. Other sites indicate the same in my reading. But this doesn't seem to be true. I have updated an image, using the same name, several times. Each time I update and refresh my browser, the new image (with the same name) displays. I understand from this article that the old image should display unless I use a new name. Do you happen to know where the misunderstanding is? I have verified that the image in question has expires headers set on it: Request Headers: Host domain.com User-Agent Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.28) Gecko/20120306 Firefox/3.6.28 FirePHP/0.5 Accept image/png,image/*;q=0.8,*/*;q=0.5 Accept-Language en-us,en;q=0.5 Accept-Encoding gzip,deflate Accept-Charset ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive 115 Connection keep-alive Referer http://domain.com/index.php Cookie __utma=1.61479883.1332439113.1332783348.1332796726.4; __utmz=1.1332439113.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none);PHPSESSID=lv2hun9klt2nhrdkdbqt8abug7; __utmb=1.33.10.1332796726; __utmc=1; ck_authorized=true x-insight activate If-Modified-Since Mon, 26 Mar 2012 21:55:33 GMT Cache-Control max-age=0 Response Headers: Date Mon, 26 Mar 2012 22:06:50 GMT Server Apache/2.2.3 (CentOS) Connection close Expires Wed, 25 Apr 2012 22:06:50 GMT Cache-Control max-age=2592000
