• Using Linode as a proxy server wrapped in DNS to bypass paid internet services

  - by snihalani

  I have a linode server that I use for development. I was thinking of using that as a proxy server. I have noticed that most paid connections allow DNS queries but don't allow http until I pay them. I verified this by flushing my dns cache and nslookup some random websites. How do I create a proxy server that allows me to may be wrap my packets from my computer in DNS packets, relay to my linode server with ssh key authentication and act as a broker? Thanks.

• Backup data rate on Raspberry Pi maxing out at 5 Mb/s. Why?

  - by bastibe

  I set up my Raspberry Pi as a Time Machine, as documented here. At the moment, the Raspberry Pi is connected to my MacBook Pro using a direct Ethernet cable. Also, an external hard drive (laptop drive) is connected to the Raspberry Pi using the USB port. However, backups are pretty slow. Activity Monitor claims that the Network is transferring a very steady 5 Mb/s, where my Time Capsule is transferring up to 8 Mb/s with a lot of fluctuation. The Raspberry Pi self-reports (top) that its CPU is only half-used, with about equal parts afpd, usb-storage and jbd2/sda1-8. Thus, I think that the processing power of the Raspberry Pi does not seem to be the problem here. To me, this looks like there is some kind of bottleneck that maxes out at 5 Mb/s thus potentially having my backups run at less than their potential speed. To the best of my knowledge, this might be the afp-daemon, the usb-bus or the external hard drive. So, my question is, how could I identify the true culprit and what can I do about it?

• Apache won't start after creating symbolic link

  - by Carlin

  I'm installing apache for the first time and trying to display some webpages on localhost. Apache's default path for serving web pages is /var/www/html/ but I don't have permissions to write there. Rather than change ownership of the entire directory, I decided to get rid of the /html/ folder in /var/www/ and created it in my home directory. Then I made a symbolic link ln -s /home/me/html/ /var/www/ hoping Apache would serve web pages from my home directory while keeping the default path and following the symbolic link to my home directory. When I go to start the apache service with service httpd start I get Job failed. See system journal and 'systemctl status' for details.

• RAID 5 configuration and future expansion

  - by Alexis Hirst

  hi, I am building a PC to act as a file server among other things, and I was wondering whether it is a good idea to create 2 partitions on the RAID 5 array, one for OS one for data, or to have a separate disk for OS and use array for data. Also, one day i may want to add another disk to the array, so would there be any issues if I had the OS partition on the RAID5 array when it came to resizing the data partition?

• Gateway GT5220 Boot/POST Failure

  - by John Rudy

  I have a Gateway GT5220 I'm troubleshooting. It is, in fact, the machine I just gave my father for his birthday a couple months ago. (Prior to that, it was my home PC. My home PC is now the MacBook on which I'm writing this.) Before going any further, I suspect that the answer will be, "It's worse than that, it's dead, Jim, it's dead, Jim, it's dead, Jim." At least, mobo and/or CPU. The initial symptoms were as follows: Turn on power All fans fire up (thus making it so I can't hear if the hard drive is spinning or not, nor are my hands sensitive enough anymore to feel it) No LEDs remained lit on the front panel. (Initially, the hard drive indicator flashed briefly.) No beep, no video, no nothing. Following some advice I found here, I tried to "drain the stored power." After following those steps, the new symptoms were: Turn on power All fans fire up The front panel LEDs remained lit! After about 20, maybe 30 seconds, we had video! Sort of. We got to the Gateway splash/POST screen, which appeared thoroughly corrupted. How corrupted? Well, I imagine it's what a POST screen would look like after reading the wrong passage out of the Necronomicon: It stayed there. I gave it at least 5, maybe 6 minutes, and it didn't move. So I shut her down, started her up again, and now (this is where we currently stand, symptomatically) we have this: Turn on power All fans fire up The front panel LEDs remain lit No video, no beep, no nothing. I'm a software guy; haven't done real hardware troubleshooting in years. My gut tells me that the mobo and/or CPU is fried, and unfortunately my gut didn't get to be as big as it is being wrong all the time. :( In addition to the link above, I have read all of the following (trying to save you some LMGTFY trouble): Gateway Support POST Error Messages and Handling About a zillion (useless) POST beep code sites A kioskea.net post indicating that most likely we're at what I consider "total loss" (mobo and/or CPU) My questions: Are there any conditions other than mobo/CPU that could cause symptoms like these? Is it worth my time to try the next hardware troubleshooting step?(IE, remove all non-critical hardware from the machine, try to boot, systematically replace one by one until we find the failing component) Which mobos will fit in the Gateway GT5220 case (with rear ports correctly aligned)? (Why this is not a dupe: I wouldn't have posted this question if it hadn't been for the funkadelic possessed video display on the one occasion we got video out. I think that justified this not being an exact dupe. Of course, if the community overrules, I will understand.)

• auto copy newest folders and images in MyPictures folder to USB drive

  - by TVersmet

  I drop lots of photos in a day into the My Documents/My Pictures folder. I archive at the end of each day to USB drives, to be stored offsite. What I would like is someway to automate the process. By example, a small app or script I can simply double-click and it will scan the My Pictures folder for the newest folders and images and copy them to the USB drive until the drive is full. It doesn't matter if I get redundancy from the previous days saved images, so long as the newest images and folders are always the first to get copied. Well, that's my request. Thanks for reading.

• Process not Listed by PS or in /proc/

  - by Hammer Bro.

  I'm trying to figure out how to operate a rather large Java program, 'prog'. If I go to its /bin/ dir and configure its setenv.sh and prog.sh to use local directories and my current user account. Then I try to run it via "./prog.sh start". Here are all the relevant bits of prog.sh: USER=(my current account) _CMD="/opt/jdk/bin/java -server -Xmx768m -classpath "${CLASSPATH}" -jar "${DIR}/prog.jar"" case "${ACTION}" in start) nohup su ${USER} -c "exec ${_CMD} >>${_LOGFILE} 2>&1" >/dev/null & echo $! >${_PID} echo "Prog running. PID="`cat ${_PID}` ;; stop) PID=`cat ${_PID} 2>/dev/null` echo "Shutting down prog: ${PID} kill -QUIT ${PID} 2>/dev/null kill ${PID} 2>/dev/null kill -KILL ${PID} 2>/dev/null rm -f ${_PID} echo "STOPPED `date`" >>${_LOGFILE} ;; When I actually do ./prog.sh start, it starts. But I can't find it at all on the process list. Nor can I kill it manually, using the same command the shell script uses. But I can tell it's running, because if I do ./prog.sh stop, it stops (and some temporary files elsewhere clean themselves out). ./prog.sh start Prog running. PID=1234 ps eaux | grep 1234 ps eaux | grep -i prog.jar ps eaux >> pslist.txt (It's not there either by PID or any clear name I can find: prog, java or jar.) cd /proc/1234/ -bash: cd: /proc/1234/: No such file or directory kill -QUIT 1234 kill 1234 kill -KILL 1234 -bash: kill: (1234) - No such process ./prog.sh stop Shutting down prog: 1234 As far as I can tell, the process is running yet not in any way listed by the system. I can't find it in ps or /proc/, nor can I kill it. But the shell script can still stop it properly. So my question is, how can something like this happen? Is the process supremely hidden, actually unlisted, or am I just missing it in some fashion? I'm trying to figure out what makes this program tick, and I can barely prove that it's ticking! Edit: ps eu | grep prog.sh (after having restarted; so random PID) 50038 19381 0.0 0.0 4412 632 pts/3 S+ 16:09 0:00 grep prog.sh HOSTNAME=machine.server.com TERM=vt100 SHELL=/bin/bash HISTSIZE=1000 SSH_CLIENT=::[STUFF] 1754 22 CVSROOT=:[DIR] SSH_TTY=/dev/pts/3 ANT_HOME=/opt/apache-ant-1.7.1 USER=[USER] LS_COLORS=[COLORS] SSH_AUTH_SOCK=[DIR] KDEDIR=/usr MAIL=[DIR] PATH=[DIRS] INPUTRC=/etc/inputrc PWD=[PWD] JAVA_HOME=/opt/jdk1.6.0_21 LANG=en_US.UTF-8 SSH_ASKPASS=/usr/libexec/openssh/gnome-ssh-askpass M2_HOME=/opt/apache-maven-2.2.1 SHLVL=1 HOME=[~] LOGNAME=[USER] SSH_CONNECTION=::[STUFF] LESSOPEN=|/usr/bin/lesspipe.sh %s G_BROKEN_FILENAMES=1 _=/bin/grep OLDPWD=[DIR] I just realized that the stop) part of prog.sh isn't actually a guarantee that the process it claims to be stopping is running -- it just tries to kill the PID and suppresses all output then deletes the temporary file and manually inserts STOPPED into the log file. So I'm no longer so certain that the process is always running when I ps for it, although the code sample above indicates that it at least runs erratically. I'll continue looking into this undocumented behemoth when I return to work tomorrow.

• Visio 2013 - how to rotate the entire page?

  - by loneboat

  I would like to rotate an entire page, including all of the shapes and text on it. I see here that you can supposedly hold down Control and click-drag the corner of the page to do it: http://office.microsoft.com/en-us/visio-help/rotate-a-page-HP085050946.aspx ... however I can't get this to work. Hovering over the corner does nothing initially, and when I hold Control the cursor becomes a scale/resize icon, rather than a rotate icon (per the MS article I linked to above). I have tried other modifier key combinations while hovering, but nothing seems to produce the rotate icon mentioned.

• automatic manipulation of email messages

  - by Toc

  Does it exist any web service that "filters" any email message allowing to change the subject or the content on a regexp basis and then forward it to my webmail address? For example: I want to append automatically the string "IMPORTANT! " to the subject of every message I receive with the subject containing "expiry", or I want to change any occurrence of "h2" in the body to "h1".

• Audit Windows Server/Desktop Product Key usage

  - by neildeadman

  The company I work for has a fairly big domain of Windows Desktops and Servers. We also have standalone servers that are remote to our site but we have direct access to. We need to audit our license usage across all Windows machines (including some VMs). I have tried a few products downloaded, but the key returned is not the one used during installation. I have one product that gives the last 5 characters correctly but needs to be installed so its not really suitable. I also have tried some PowerShell scripts one of which is here Ideally I am looking for one that can be used over a network and if possible can audit Office keys too. I've just tried Jelly Bean and some other product key tools that all return BBBBB-BBBBB-BBBBB-BBBB-BBBBB as the product key.

• Will HDCP cause problems with a MacBook Pro using a VGA projector?

  - by Andrew Grimm

  I'm planning on using a MacBook Pro with a projector that only has a VGA input (through the MBP's Mini DisplayPort and a Mini DisplayPort to VGA converter). Will this have problems with HDCP (High-bandwidth Digital Content Protection), either under Snow Leopard or Windows XP? I'll only be showing other people's photos, user-generated movies or PowerPoint slides. The MacBook Pro was purchased from Apple new in December 2009.

• BIOS corrupted? How to proceed? Acer Travelmate 290

  - by dtlussier

  I have a older ACER Travelmate 290 (manufactured in 2002 or 2003), which I recently tried to upgrade to Ubuntu 9.10. After doing the upgrade process it appeared as if I had a problem with my x server configuration, as on the first reboot post-install I heard the Ubuntu startup sound, but had a black screen. I thought I would then reboot again to drop down into text-mode to trouble shoot the x configuration problem. However, when I tried rebooting, something went wrong and since then when I start up the machine I get absolutely nothing except the first hardware check (i.e. HDD light flashes, CD/DVD drive spins, etc.). Other than that the screen remains totally black and I have no HDD or processor activity at all. I have tried restarting it a number of time holding down all kinds of key combinations to try and coax it into the BIOS (if possible) with no luck. I have also tried putting in both a live Linux disc and a Windows install disk without any luck. With a disk in the drive it will spin for a few seconds and then stop. All this has lead me to suspect that the BIOS is somehow corrupt (not sure about the right terminology). I have tried putting a new BIOS image and installer program downloaded from ACER on a USB key to see if it will run when I start up the machine, but no luck. I'm not sure if this method of interacting/updating/flashing the BIOS will work outside of Windows/DOS as both OSs are mentioned kind of ambiguously in the documentation. I have also taken the laptop case apart and inspected the various cards and cannot find any obviously burned out components. I'm not sure how to proceed at this point in terms of components to try, or how to try and load a new BIOS image onto the board. Any advice here would be great, especially from those with experience with this particular line of laptops. Thanks!

• How can I switch my display language to English in Windows 7?

  Hi, I live in Israel and I bought Windows 7 Professional in Hebrew. I'd like to switch the language to English. In Control Panel - Region and Language I don't have any options to switch the display language to English because only Hebrew is installed. In Windows Update, there are no language updates. I have waited three days, and still no language update. Any Ideas? Thank you.

• Software for Bluetooth headset

  I recently installed Windows 7 on my desktop and purchased a Dell BH200 headset. The problem is that the software that came with the bluetooth dongle (Bluesoleil 5) is fairly old and isn't compatible Windows 7. Bluesoleil 6 is very expensive - is there something else I can do or use to get my headset working?

• Test disk recovery

  - by AIB

  I had a 250GB hard disk having several NTFS partitions. The disk was a dynamic disk (created in windows). Now when I formatted windows (which was in another disk), the dynamic disk is shown as offline. I tried using the testdisk tool to recover the data and created a partial backup. Testdisk is able to list all partitions in the disk. All partitions are shown as type 'D' (Deleted). I want to change the 'D' to 'P' (Primary), 'L'(Logical), 'E' (Extended) appropriately and build a new partition table. If I can write the partition table to disk, the disk will be of 'basic' type and should be readable in all OS. What should be the appropriate partition types? I checked the files on the partitions and no OS was ound. So none of the partitions were bootable. Will randomly selecting P,L,E hurt the data in anyway?

• Windows XP machine not seeing external FAT32 partitions correctly

  - by Rob_before_edits

  About 8 months ago my Windows XP machine stopped being able to see FAT32 external drives when I plug them in... mostly. I will explain... It happens with all my FAT32 drives, whether they be unpowered external hard drives, powered external hard drives, SDHC cards plugged directly into the machine's card reader, or SDHC cards plugged in via a separate USB card reader. All of these drives/cards used to work fine on this machine. They all stopped working at about the same time. NTFS volumes are not affected. If I plug in NTFS external drives they are recognized right away. I even have one external drive with two partitions on it, one is NTFS which is recognized, the other is FAT32, which is not recognized. If I attach a FAT32 drive, then reboot, then the drive almost always becomes visible to the machine after the reboot. Sometimes I can plug in a FAT32 drive and it works right away. Not often though. I'd say I get lucky more often with SDHC cards than hard drives. I'm developing a theory that I only get lucky with hard drives if I'm running Acronis Disk Director when I plug them in, though that usually doesn't work either - I need more data here, this may be a red herring. Getting lucky with a hard drive is really rare, usually I have to reboot. When a FAT32 is recognized, either because I got lucky or because I rebooted, I can almost never safely disconnect it. It tells me "The device 'Generic volume' cannot be stopped right now. Try stopping the device again later". I can't seem to get around this. IIRC, I've tried closing every open window, and still no luck. Since I care about my data usually the only way to disconnect a FAT32 drive is to shut down the machine. As you can imagine, two reboots just to read a drive is getting pretty old... When the machine fails to see a FAT32 drive it usually comes up with the appropriate drive letter and the words "Local Disk" in Windows Explorer instead of the correct partition name. If I click on it I get "J:\ is not accessible. The parameter is incorrect." Before this problem arose I always clicked the "safely remove" button for everything, including SDHC cards where I think it's not necessary. I've known for a long time that this is the correct procedure for hard drives, so I don't think failing to do this was the cause of this problem (before someone asks :) Any answers or suggestions most welcome.

• Any reason not to disable the Windows pagefile given enough physical RAM?

  - by Evgeny

  The question of disabling the Windows pagefile has already been discussed quite a bit, for example here and here and here. People continue to upvote answers that say "you should not disable your pagefile even if you have plenty of RAM", but I have yet to see any concrete, verifiable reasons being given for this advice. As far as I can see, if you never need to read from the pagefile (because you have enough RAM) then performance could only be worse with it enabled due to Windows pre-emptively writing to it. At best, performance would be the same. I can't see how it could possibly be improved by writing data you never need to read. So my question is: Assuming that I have enough physical RAM for everything I do, is there any reason I should not disable the pagefile? Let's say the version of Windows is Windows XP x64 SP2 or Windows Server 2003 x64 SP2 (same thing). If it's different for Windows Server 2008 x64 I'd be interested to hear an answer for that as well. I'm looking for specific, objective reasons from good sources, not just opinions. Something like "here are the benchmarks done with and without a pagefile and the results were better with a pagefile, even with enough RAM" or "according to this MS KB article problem X occurs if you disable the pagefile". So far the only reasons I've seen mentioned are: Even if you think you have enough RAM you might run out. OK, but for the purposes of this question, let's just take it as a given that I have enough. Maybe I only ever read my email and I have 16GB RAM. Or 128GB. Or 1TB. Or whatever - but it's enough for 100% of what I do, 100% of the time. Another way to think of it is: if I have x MB physical RAM and y MB pagefile and I never run out of RAM in that configuration, would I not be better off, performance-wise, with x+y MB physical RAM and no pagefile? Windows is "used to" having a paging file and it might not function as reliably (from Understanding the Impact of RAM on Overall System Performance That's rather vague and I find it hard to believe, given that MS has provided the option to disable the pagefile. Windows knows what it's doing better than you. No - it doesn't know that I won't run more programs or load more data, but I do.

• Sync iPhone applications in iTunes

  - by Uwe Honekamp

  Suppose I have one the one hand one iTunes library on a PC used to sync Outlook contacts and calendar plus on the other hand one iTunes library on a Mac that syncs music, podcasts, apps, ringtones, etc. Both libraries are based on iTunes 9.0.2. It turns out that the iTunes library on the PC always tries to sync apps and ringtones as well. Unfortunately, this boils down to deleting apps and ringtones from the iPhone because the apps are not part of the iTunes library on the PC. After unchecking the checkbox to sync apps and ringtones and plugging the iPhone into the Mac the checkbox is also unchecked on the Mac. It seems as if the settings for syncing apps and ringtones are stored on the iPhone rather than in the particular iTunes library. Whenever syncing apps and ringtones is active on one machine it is also active on the other and vice versa. How can I make the PC ignore apps and ringtones and only sync contacts and calendar?
