• Cannot set up dual monitors correctly in Fedora15 with KDE.

  - by adivasile

  I have 2 monitors: 24" LCD connected via DVI(primary) 19" LCD connected via VGA(secondary) Everytime Fedora starts the second display is always set to clone the first one and they both run at 1280x1024 and I always have to disable the 19" monitor, in order for the bigger one to run at 1920x1080. I want to set them up so that my secondary monitor extends the primary one.The problem is that no matter what kind of configuration I choose it has no effect.My secondary monitor remains disabled. I've tried using both the Display manager from KDE and the ATI Control Panel and the behaviour is always the same.The moment I click apply, the screen flickers and nothing changes. I've succesfully used the extended setup in Fedora15 with Gnome3. I have a RadeonHD 4300 series videocard and I'm using the drivers downloaded from the AMD site. This is the output of xrandr -q : Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 1920 x 1920 VGA-0 connected (normal left inverted right x axis y axis) 1280x1024 75.0 60.0 1280x960 60.0 1152x864 75.0 1024x768 75.0 70.1 66.0 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 75.0 72.8 66.7 59.9 720x400 70.1 DVI-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.0*+ 60.0 1680x1050 59.9 1600x900 60.0 1280x1024 75.0 60.0 1280x960 60.0 1152x864 75.0 1280x720 60.0 1152x720 60.0 1024x768 75.0 60.0 832x624 74.6 800x600 75.0 60.3 640x480 75.0 59.9 720x400 70.1 Later edit: The problem seems to come from the ATI drivers.I managed to set up the monitors like I wanted after I uninstalled the drivers. Unfortunately I'm working on an OpenCL project so I had to reinstall them.The moment I did that, all my previous settings were forgotten and I was back to square one.

• Network Management Cable Labeling Techniques and their alternatives [closed]

  - by Alex

  Possible Duplicate: What is the most effective solution you used to label cables? Yes i know there are a lot of howtos and already answered questions about this topic, like this one: How do you organise the cables in your racks? Currently i am searching the web for different techniques (alternatives) for labeling the cables at the server racks and/or data centers. Unfortunately i do not have any experience with labeling/documentation of network cables in a large scale. As far as I could lookup by now the current labeling techniques are coloring and a self defined print-labeling technique (numbering, text) maybe also according to a standard which are usually used. I want to know if QR, RFID (ok RFID in a data center would be stupid due to the radio frequency wouldn't it be?), Barcodes or similar (??) have already been used by some administrators or why they did not consider such techniques at all? Too complicated (with QR scanner etc..) if you are in front of the cables and want to get quick feedback for what the cable is? What alternatives are out there? Advantages/Disadvantages? Best-Practice? I would appreciate any help on this topic, thank you! Regards, Alex

• Bash mine script, please

  - by HomelyPoet

  The script, in and of its self, is fairly self-explanatory. Use if You so desire; any and all criticism wouldst be appreciated, as wouldst any suggestions for improvement. First iteration was writ upon OS X 10.5.8 Leopard, current iteration was run upon OS X 10.6.4 Snow Leopard with Safari 5.0.2 (6533.18.5). Also, any illumination as to why the first line ' if [ -f ] ' works, but ' if [ -f ~/Library/Safari/LocalStorage/*.localstorage ] ' generates an error?

• Remote search system for samba shares

  - by fostandy

  I have several shares residing on a samba server in a small business environment that I would like to provide search facilities for. Ideally this would be something like google desktop with some extra features (see below), but lacking this the idea is to take what I can get, or at least get an idea for what is out there. Using google desktop search as a reference model, the principle additional requirement is that it is usable from clients over the network. In addition there are some other notes (note that none of these are hard requirements) The content is always files, residing on a single server, accessible from samba shares. Standard ms office document fare Also a lot of rars and zips which it is necessary to search inside. Permissions support, allowing for user-based control to reflect current permission access in samba shares. The userbase will remain fairly static, so manual management of users is fine. majority of users will be Windows based I know there are plenty of search indexers out there: beagle and tracker seem to be the most popular. Most do not seem to offer access control and web-based/remote search does not seem to be high priority. I've also seen a recent post on the samba mailing list asking for pretty much the exact same thing. (They mention a product called IBM OmniFind Yahoo! Edition and while their initial reception seems positive, I am pretty skeptical. RHEL 4? Firefox 2? Updated much?) What else is out there? Are you in a similar situation? What do you use?

• Installed Paragon HFS+ for Windows 8, now my pc won't recognize the external firewire drive

  - by Steve

  I'm not incredibly knowledgeable about computers and I really need some help. Just got a Seagate external firewire drive this morning. I downloaded the necessary pc driver (Paragon HFS+ for Windows 8) through their website per the instructions that came with the drive. After installation, I restarted and the pc recognized the firewire drive just fine. About three hours into copying files from my pc to the firewire drive, it gave me an error and told me the files couldn't be copied. When I clicked to get out of the message, the computer crashed. After an hour of it trying to repair itself in safe mode, it restored me to an earlier version before the system crashed. Here's my current dilemma: The Paragon HFS+ is still showing up in my programs as installed, but the Device Manager is not recognizing the drive. When I try to uninstall and reinstall Paragon, it interrupts me with a message saying "The setup must update files or services that cannot be updated while the system is running" and basically gives me the finger. I have no idea what to do now, as it won't let me uninstall and reinstall Paragon, and I have no idea why it crashed my computer in the first place. Is there possibly another Mac - PC firewire driver I can try downloading instead? I really don't know what I'm doing and any help would be greatly appreciated.

• Using smartctl to get vendor specific Attributes from ssd drive behind a SmartArray P410 controller

  - by Lairsdragon

  Recently I have deployed some HP server with SSD's behind a SmartArray P410 controller. While not official supported from HP the server work well sofar. Now I like to get wear level info's, error statistics etc from the drive. While the SA P410 supports a passthru of the SMART Command to a single drive in the array the output I was not able to the the interesting things from the drive. In this case especially the value the Wear level indicator is from interest for me (Attr.ID 233), but this is ony present if the drive is directly attanched to a SATA Controller. smartctl on directly connected ssd: # smartctl -A /dev/sda smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF READ SMART DATA SECTION === SMART Attributes Data Structure revision number: 5 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 3 Spin_Up_Time 0x0000 100 000 000 Old_age Offline In_the_past 0 4 Start_Stop_Count 0x0000 100 000 000 Old_age Offline In_the_past 0 5 Reallocated_Sector_Ct 0x0002 100 100 000 Old_age Always - 0 9 Power_On_Hours 0x0002 100 100 000 Old_age Always - 8561 12 Power_Cycle_Count 0x0002 100 100 000 Old_age Always - 55 192 Power-Off_Retract_Count 0x0002 100 100 000 Old_age Always - 29 232 Unknown_Attribute 0x0003 100 100 010 Pre-fail Always - 0 233 Unknown_Attribute 0x0002 088 088 000 Old_age Always - 0 225 Load_Cycle_Count 0x0000 198 198 000 Old_age Offline - 508509 226 Load-in_Time 0x0002 255 000 000 Old_age Always In_the_past 0 227 Torq-amp_Count 0x0002 000 000 000 Old_age Always FAILING_NOW 0 228 Power-off_Retract_Count 0x0002 000 000 000 Old_age Always FAILING_NOW 0 smartctl on P410 connected ssd: # ./smartctl -A -d cciss,0 /dev/cciss/c1d0 smartctl 5.39.1 2010-01-28 r3054 [x86_64-unknown-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net (Right, it is complety empty) smartctl on P410 connected hdd: # ./smartctl -A -d cciss,0 /dev/cciss/c0d0 smartctl 5.39.1 2010-01-28 r3054 [x86_64-unknown-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net Current Drive Temperature: 27 C Drive Trip Temperature: 68 C Vendor (Seagate) cache information Blocks sent to initiator = 1871654030 Blocks received from initiator = 1360012929 Blocks read from cache and sent to initiator = 2178203797 Number of read and write commands whose size <= segment size = 46052239 Number of read and write commands whose size > segment size = 0 Vendor (Seagate/Hitachi) factory information number of hours powered up = 3363.25 number of minutes until next internal SMART test = 12 Do I hunt here a bug, or is this a limitation of the p410 SMART cmd Passthru?

• Can I have a single solid state drive and a RAID array on the same machine?

  - by jaminto

  Hi- To summarize, i'm looking to use a single solid state drive as my primary drive, and two conventional sata drives in a RAID 1 configuration for data. I am trying to install 64-bit Windows 7 onto this configuration. Is this possible? Here are the details: I built a desktop that has been running 64-bit Vista on two 500Gb in a RAID 1 array for a few years. I just purchased an Intel X25-M 80Gb Sata Solid-State Drive, and was planning on using this a my primary drive, and keeping the RAID 1 array as my data drive. I added the SSD drive and in the RAID setup, configured it as a RAID 0 array of only one disk. Then, I tried to do a clean install of windows 7 64-bit, but got stuck in the "Missing driver for CD/DVD drive" black hole of selecting driver files and Windows telling me that i don't have the appropriate driver for my hardware. The missing hardware is NOT a CD/DVD drive, since i'm installing off of my only CD/DVD drive. Plus at one point i was able to point it at a driver for my raid controller, and then my hard drives magically showed up as browsable sources for finding drivers for some other unnamed device that setup couldn't recognize. After a few hours of trying drivers (this was a very slow process) i decided to reboot and look at the BIOS settings. I'm using an ASUS M2A-VM motherboard which has an ATI SB600 RAID controller on board. I switched the "On board SATA Type" setting from "SATA" to "AHCI" thinking that since AHCI is an Intel thing, this would help. Unfortunately, this abandoned my RAID configuration, and my previously mirrored drives are showing up as separate drives when i boot into my current windows installation. Am i trying to do the impossible here? Should i just buy a separate SATA/RAID PCI card and plug the SSD into that? Any help would be greatly appreciated.

• Trying to use Nginx try_files to emulate Apache MultiViews

  - by Samuel Bierwagen

  I want a request to http://example.com/foobar to return http://example.com/foobar.jpg. (Or .gif, .html, .whatever) This is trivial to do with Apache MultiViews, and it seems like it would be equally easy in Nginx. This question seems to imply that it'd be easy as try_files $uri $uri/ index.php; in the location block, but that doesn't work. try_files $uri $uri/ =404; doesn't work, nor does try_files $uri =404; or try_files $uri.* =404; Moving it between my location / { block and the regexp which matches images has no effect. Crucially, try_files $uri.jpg =404; does work, but only for .jpg files, and it throws a configuration error if I use more than one try_files rule in a location block! The current server { block: server { listen 80; server_name example.org www.example.org; access_log /var/log/nginx/vhosts.access.log; root /srv/www/vhosts/example; location / { root /srv/www/vhosts/example; } location ~* \.(?:ico|css|js|gif|jpe?g|es|png)$ { expires max; add_header Cache-Control public; try_files $uri =404; } } Nginx version is 1.1.14.

• Cannot connect on TFS 2012 server through SSL with invalid certificate

  - by DaveWut

  I saw the problem on some forums and even here, but not as specific as mine. So here's the thing, So I've configured a TFS 2012 server, on one of my personnel server at home, and now, I'm trying to make it available through the internet, with the help of apache2 on a different UNIX based, physical server. The thing is working perfectly, I don't have any problem accessing the address https://tfs.something.com/tfs through my browser. The address can be pinged and I do have access to the TFS control panel through it. How does it work? Well, with apache2 you can set a virtual host and set up the ProxyPass and ProxyPassReserver setting, so the traffic can externally comes from a secure SSL connection, through a specified domain or sub-domain, but it can be locally redirect on a clear http session on a different port. This is my current setup. As I already said, I can access the web interface, but when I'm trying to connect with Visual Studio 2012, it can't be done. Here's the error I receive: http://i.imgur.com/TLQIn.png The technical information tells me: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. My SSL certificate is invalid and was automatically generated on my UNIX server. Even if I try to add it in the Trusted Root Certification Authorities either on my TFS server or on my local workstation, it doesn't work. I still receive the same error. Is there's a way to completely ignore certificate validation? If not, what's have I done? I mean, I've added the certificate in the trusted root certificates, it should works as mentioned on some forums... If you need more information, please ask me, I'll be pleased to provide you more.

• is it worth to use load balancer on web server/website

  - by user427969

  I have a website and a while ago, the web server of the company hosting my website was down for about a day. I consulted the company for a solution on how i can stop this from happening in future and they suggested to have a second machine and which will be connected to my current website/web server by a "load balancer" (at an additional huge cost!!!). The second machine will be replicate of the first one and so if i goes down, the other will always be running. ---- Explanation ----- My hosting company suggested that it will be a good idea to have a second machine running at the same time and both the machines will be connected by a load balancer which reduces the rist of a downtime. The second machine will be a mirror of the first and any changes to first must be replicated in the second. I don't mind spending money if it really saves my website from going down. I want to know is it worth having this "load balancer" for my purpose? My website is a 24/7 service. I cannot afford an outage of 24 hours/1 hour. I don't mind using this "load balancer" as far as it is really worth. I am not sure if its just a marketing trick of my hosting company or really a "best" solution Thanks for help. Regards

• PHP extension causes symbol lookup error

  - by Christian

  Dear, I installed - or better tried to - the NMCryptGate Extension for PHP on my Debian 5.0.8 server. I did this by compiling the sources which came up with no error message. Calling phpinfo() I can see the extension as enabled. BUT, whenever I try calling a method from this extension I get an error logged to the apache error log: /usr/sbin/apache2: symbol lookup error: /usr/lib/php5/20060613+lfs/nmcryptgate.so: undefined symbol: nmlistalloc What is missing? I got two packages from the software company: the php module sources and some files which should - according to their path inside the tar - go to /usr/local/bin|doc|include|lib. I moved them there without any effect. Each of these two packages has its own config file almost looking the same: \# libnmcryptgate.la - a libtool library file \# Generated by ltmain.sh - GNU libtool 1.3.4 (1.385.2.196 1999/12/07 21:47:57) \# \# Please DO NOT delete this file \# It is necessary for linking the library \# The name that we can dlopen(3) dlname='' \# Names of this library library_names='libnmcryptgate.so.1 libnmcryptgate.so libnmcryptgate.so' \# The name of the static archive old_library='' \# Libraries that this one depends upon dependency_libs=' -L. -L/usr/ssl/lib -L/usr/local/ssl/lib -L/usr/local/lib -lssl -lcrypto' \# Version information for libnmcryptgate current=1 age=0 revision=29 \# Is this an already installed library installed=yes \# Directory that this library needs to be installed in libdir='/usr/local/lib' I tried several ways to get it right: moving files, symlinking, changing configurations - always followed by restarting apache - no success. I guess I just have to move the files to the correct location or change the libdir inside the config files but meanwhile I'm totally confused by the two packages: do I need both, which config rules what, do I have to use the libdir variable? And for what? ... Anybody out there hinting me to my source of failure? Thank you in advance, regards, Christian

• Is there a way to "burn" audio to an ISO? (as an audio CD)

  - by Sootah

  I have an audiobook that I've downloaded via their download manager, and it's loaded into their cutesy little audio program that they force you to use. I can play the book just fine using their proprietary software, and while it's annoying when using my PC, it's utterly UNBEARABLE when I try to listen to it on my Blackberry. The program is INSANELY slow, it literally takes around 30 seconds to switch between tracks, so if I've forgotten where I am in the book it takes me around 15 minutes to finally get to where I was at. I've looked everywhere on how to transcode the book to .MP3, but evidently with their current format it's either extremely convoluted (and I have no desire to dick around with installing some older version of the codec, getting a different transcoding app, and then wrestling with getting it to actually work). Since I'm able to burn a copy of the book to an audio CD, I figure the best way to go about this is to just make the CDs and then rip them off of those to .MP3. In order to avoid wasting two hours, not to mention 14 CD-R's, I was wondering if there's a way to "burn" to an .ISO instead of an actual CD-R. I currently have SlySoft's Virtual CloneDrive installed, so I can mount .ISO's easily enough, but now I want to actually create an ISO via the CD burning process. Just in case I've not explained myself very well, here is an overview of what I intend to do: "Burn" a set of Audio CD .ISOs from the audiobook (hopefully I can do this using Windows Media Player, otherwise I'll be forced to use the audiobook app) Mount an .ISO in Virtual CloneDrive Rip the audio tracks on the mounted .ISO to .MP3s Repeat steps 2-3 until the entire book is in .MP3 format Copy .MP3s to my Blackberry so that I'm not driven insane every time I want to listen to the book in the car, and be able to use Winamp when listening on my computer EDIT: I'd suppose a rather concise way to put it is that I need something that will emulate a CD-R drive, so that you can select it as the output drive in whatever app your burning the audio CD from. (I'd suppose that when you "insert a blank CD-R" the app would then ask you what file to save to)

• time sync with ntpd

  - by guthrie

  I run Debian on several systems, and their times do not seem to stay in sync. I can run ntpdate manually, but I thought that I should have an ntpd running that would automate that. I did check with apt and apt-cache but don't find any ntpd (or associated ntpq), not any such names in my system (locate...), but ntp-doc does still describe them. Looking around I see that there is an ntpdate-debian command, and it uses /etc/default/ntpdate for servers (instead of the standard /etc/ntp.conf), but even thought that file is there and has "yes" indicated to use ntp.conf, it fails with "no servers can be used", although ntpdate works fine. Is this just a layer over ntpdate, any reason to use it instead? So, why are they missing, do I need them, how do I automate time updates? Associated, two of my machines are virtualized on a MSoft VM, how is it that their clocks drift, and both to different values? (The underlying Windows machine clock seems stable). I see a few old notes about time & ntp problems on VMware, didn't find anything either current or relating to MSoft VMs. Anything I did see says just to use ntpd, but as above, ...?!

• Sharing disk volumes across OpenVZ guests to reduce Package Management Overhead

  - by andyortlieb

  Is it feasible to create a single "master" OpenVZ guest who would only be used for package management, and use something like mount --bind on several other OpenVZ guests sort of trick them into using the environment installed by the master guest? The point of this would be so that users can maintain their own containers, and yet stay in sync with the master development environment, so they'll always have the latest & greatest requirements without worrying too much about system administration. If they need to install their own packages, could put them in /opt, or /usr/local (or set a path to their home directory)? To rephrase, I would like several (developer's, for example) OpenVZ guests whose /bin, /usr (and so on...) actually refer to the same disk location as that of a master OpenVZ guest who can be started up to install and update common packages for the environment to be shared by all of this group of OpenVZ guests. For what it's worth, we're running Debian 6. Edit: I have tried mounting (bind, and readonly) /bin, /lib, /sbin, /usr in this fashion and it refuses to start the containers stating that files are already mounted or otherwise in use: Starting container ... vzquota : (error) Quota on syscall for id 1102: Device or resource busy vzquota : (error) Possible reasons: vzquota : (error) - Container's root is already mounted vzquota : (error) - there are opened files inside Container's private area vzquota : (error) - your current working directory is inside Container's vzquota : (error) private area vzquota : (error) Currently used file(s): /var/lib/vz/private/1102/sbin /var/lib/vz/private/1102/usr /var/lib/vz/private/1102/lib /var/lib/vz/private/1102/bin vzquota on failed [3] If I unmount these four volumes, and start the guest, and then mount them after the guest has started, the guest never sees them mounted.

• How do I renew a Web Server certificate in Windows Server 2008?

  - by Mark Seemann

  The SSL certificate for my web site just expired a few days ago, and I would like to renew it. I originally issued it two years ago using my Windows 2008 Certificate Authority, and it's worked without a hitch in all that time, so I would like to renew the certificate as simply as possible to make sure that all the applications relying on that certificate continue to work. I can open an MMC instance and add the Certificates snap-in for the Local Computer. I can find the relevant certificate under Personal, but I can't renew it. When I select Renew certificate with new key I get the following message: Web Server Status: Unavailable The permissions on the certificate template do not allow the current user to enroll for this type of certificate. You do not have permission to request this type of certificate. However, I can't understand this, as I'm logged on as a Domain Admin and I'm running the MMC instance in elevated mode. I've checked the Web Server certificate template, and Domain Admins have the Enroll permission on this template. FWIW, I also tried rebooting the server. How can I renew the certificate?

• How to wire 20 computers and 20 phones and 1 server into LAN?

  - by John Smith

  I have currently 3 switches Two Netgear JFS524 with 24 slots, One Belkin with 16 slots. Server DSL Internet Router. Main question is how to connect switches together, two Netgear's are next to each other, yet one is about 100 feet away and holds about 5 computer and 5 phones. If i connect them with only 1 wire will that limit bandwidth? e.g. all 23 computers will be limited to speed of one CAT5e cable? If i connect switches with 2 cables will this give speed boost? What's the ideal scenario should i just move the third switch next to other two? Will the speed of computer connected to white switch be same as computer connected to top switch? Will moving white switch right next top switch and having 16 wires comming 100 feet instead of 1 wire comming 100 feet make it faster? EDIT 1: I actually have NETGEAR ProSafe GS105 Gigabit switch its only has 4 ports in it though, you think i can have use of it in current setup? Like connect all 3 switches and server into it and keep internet router and phone server on one of the slower switches EDIT 2: Everyone mention gigabit switches, but will they do any difference with 10/100 network cards? I then have to use gigabit cards in every computer too? I could in server perhaps, but users will be 10/100

• DisableCrossAccountCopy not working on some Outlook installs, working on others, both going against Exchange

  - by MikeBaz

  As part of a mail migration project from one Exchange organization to another, we need to be able to prevent users from moving/copying messages between their accounts in each organization. (Yes, users will think this is evil; no, it's not my decision; yes, users will hate us.) Luckily, we thought, Outlook 2010 provides the DisableCrossAccountCopy registry value/policy (cf. http://technet.microsoft.com/en-us/library/ff800883.aspx). (Because you can't do multiple Exchange organizations in a single profile before Outlook 2010, this only matters on Outlook 2010. Yes, I'm ignoring for the sake of this question copy/move to/from the filesystem.) In our test lab, in a test forest with a test Exchange organization, with a second Exchange account added to the profile in either of the "real" Exchange organizations, with the value set to "*", everything works as expected. On a workstation in one of the production domains, however, the setting does not seem to work. We have tried it under HKCU, HKLM, HKCU\Software\Policies, and HKLM\Software\Policies. It simply seems to be ignored. The value was set in the OCT on a test machine, but the OCT (and the ADM/ADMX file) have the wrong type for the value. We have located the value in the registry and removed it everywhere it is found, we think, and put it back in HKCU, but it still isn't taking. At the moment, a clean Outlook install is not an option - even if it was, we at this point would need to know what to do to fix the pushed copy (I didn't push the copy out to thousands of machines, I've just been asked to help clean up the current mess). Thoughts?

• HTPC/DVR computer won't go into standby

  - by Robert

  When I select Start-Turn off computer-Standby the 'turn off computer' option window closes, and then nothing else happens. I can start new applications, and Windows acts like I never selected standby. I ran it for several hours after that. If I have a TV program scheduled to record when I select standby I get a window (the Pinnacle TV software) asking if I'm sure, there are programs scheduled to record - and the computer just keeps running after I select yes, never going into standby. I added that detail as it shows the standby process is starting. [This problem also happens if a TV program is not scheduled, so the scheduler task in not running/in memory. This problem happens regardless of whether I'm not watching TV. This problem happens regardless of whether Media Center is running (it usually isn't, I'm using Pinnacle to watch TV).] I looked at "How to troubleshoot hibernation and standby issues in Windows XP" http://support.microsoft.com/kb/907477 - ACPI is enabled, and "standby" is an option in "Power Options Properties." So it appears to be setup correctly. Windows XP SP3 Media Center Edition, all current updates installed.

• A separate user for each task?

  - by Mark Tomlin

  I just got a VPS sver the other day, I'm new to server administration, but not that new to Ubuntu (11.04). I use it in my living room as the HTPC, and I had a previous VPS that I used on and off for a team speak server. This one I'm setting up for long term use. So I would like to know the best practice when it comes to websites and tasks that I have the server proforming. I understand that it could be beneficial to separate each website into it's own usergroup or under its own username. I would setup nginx so that it could read all of the users directors (and thus each website) but could not touch anything else. The same with the TeamSpeak, should I make a user for TeamSpeak so that it operates within its own confined area or is this overkill? I do have access to root on the sever and my current plan is to run about 4 websites and a TeamSpeak server. My stack is Linux (Ubuntu 11.04 LTS), nginx, and PHP 5.4.3 (using the PDO SQLite 3 built in driver for the database). Should PHP have it's own user group or is it ok to place it in with nginx?

• Windows 2008 Standard upgrade to Windows 2008 Enterprise failure

  - by Archit Baweja

  Sidestory, I was in the process of setting up a second Exchange 2010 server for DAG support, when I realized that my box needed Windows 2008 Enterprise edition. The box currently has Windows 2008 Standard Windows update including SP2 Exchange 2010 with CAS, HT, Mailbox roles Domain Services role File Services role. When I try to upgrade to Windows 2008 Enterprise, I initially got a "your current version of windows is more recent than the intallation media", something to that effect. My first guess was it may be SP2 related, so I uninstalled SP2, restarted and tried again. This time it gave me an error to the effect Windows could not configure one or more windows components. Please restart and try the update again. This was at the last stage of the Windows 2008 Enterprise install when it says "Completing installation". So I removed Domain Services role (including demoting it as a DC). However I get the same error again. Anyone see something like this before and have any suggestions? Also , is there a log file the windows upgrade program spits out that I can consult to see what component exactly is interfering? Update 1 Based on some googling I finally found the setup log file, and it seems that Windows setup had an issue determining the .Net 3.0 "feature" being installed or uninstalled. So based of of a win7/vista technet article I'm going to retry the upgrade after removing the .Net 3.0 feature.

• Managing Apache to Compensate for WebDAV's Security Masking

  - by Tohuw

  When a user creates a file via WebDAV, the default behavior is that the file is owned by the user and group running the Apache process, with a umask of 022. Unfortunately, this makes it impossible for unprivileged users to write to the files by other means without being a member of the group Apache runs under (which strikes me as a particularly bad idea). My current solution is to set umask 000 in Apache's envvars and remove all world permissions from the webdav parent directory for the user. So, if the WebDAV share is /home/foo/www, then /home/foo/www is owned by www-data:foo with permissions of 770. This keeps other unprivileged users out, more or less, but it's hokey at best and a security disaster awaiting at worst. From my research and poking around at mod_dav and Apache, I cannot find a reasonable solution short of a cron job flipping all the permissions back (I'd rather not have the load and increased complexity on the server). SuExec won't work, either, because WebDAV operations are not going to execute as a different user. Any thoughts on this? Thank you.

• Poor gaming performance with hyper-v installed in windows 8

  - by SnowCrash

  I am getting very poor gaming performance on my Windows 8 host OS with Hyper-V installed but no guest machines running. For example World of Tanks reports 60-70 FPS without Hyper-V installed and 4-14 FPS with it installed. A similar, dramatic, hit is observed in several other games so the issue is not WoT specific. To make the point clear, I am not trying to run games in a virtual machine. I don't even have a VM running while observing this effect. I simply have the Hyper-V feature installed. My system specs: AMD Phenom II 965 (3.4 GHz) AMD Radeon 6950 2GB (XFX Double D HD-695X-CDFC) 16GB DDR3 1333 AMD 790GX chipset Mainboard (Gigabyte GA-MA790GPT-UD3H) I have tried every AMD driver from 12.8 to the current 12.11beta8, virtualization is enabled in the BIOS settings, the onboard 3300HD video device is disabled in BIOS and I have read the MSDN blog entry here regarding a similar issue in Server 2008 that was resolved in 2008 R2 (and hopefully not regressed in Win 8). I'd like to be able to use Hyper-V for development and testing at home (I am a sysadmin/software developer professionally). If, however, I can't also use my home system for entertainment I'll have to scrap those plans.

• Why would Windows use slower network interface despite route metrics?

  - by tim11g

  On my previous notebook, the Dell/Broadcom wireless adapter had an option to automatically disable wireless when a wired network is connected, so I never dealt with multiple active interfaces. My current system has an Intel wireless adapter, and they apparently haven't figured out how to turn it off when there is a wired connection. Unless I explicitly remember to disable wireless when docked, the connection is active. That shouldn't be a problem (in theory), since the route metric will cause traffic to go over the fastest network (as indicated by the lowest metric in the routing table). Apparently not - I'm running a backup and seeing the throughput at 25Mbps or so (which is consistent with 802.11g) when a perfectly good Gigabit Ethernet interface is also connected. IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 192.168.1.254 192.168.1.104 10 0.0.0.0 0.0.0.0 192.168.1.254 192.168.1.109 25 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 Windows has correctly identified the Ethernet interface (.104) and assigned it the lower (preferred) metric. So the Ethernet interface should be used exclusively, right? Why is the Ethernet connection not being used? What other factors are involved? (This is with Windows 7 if it makes a difference)

• where can I find the user in this IIS error 'Login failed for user 'IIS APPOOL\Web2'

  I encounter the following error: Cannot open database "testbase" requested by the login. The login failed. Login failed for user 'IIS APPPOOL\Web2'. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.SqlClient.SqlException: Cannot open database "testbase" requested by the login. The login failed. Login failed for user 'IIS APPPOOL\Web2'. So, where can I give this user Web2 permission? (By the way, the server do not have such user Web2 but there is a folder called Web2 located at the wwwroot folder.) I search for answers but all failed as follows: [1] Add the user IUSR to the folder and give it read permission.

• Determine the time difference between two linux servers

  - by Paul

  I am troubleshooting a latency network issue on a network. It is probably a nic or cabling issue, but while I was going through the process of figuring it out, I was looking at the timings of a ping packet leaving a network card and arriving at another server. Both linux. So I have tcpdump running on both, and I issue a ping from one to the other, and back again, and looking at the timing differences might have shed light on where the latency is coming from. It is an academic exercise now, as I need to eliminate some more fundamental causes, but I was curious as to how this could be achieved. Given that ntpd is installed and running on two servers, how can I confirm the current time discrepency between the two servers, to whatever level of accuracy is possible - given that we are talking about latency on a local lan, which is ideally a millisecond or so. NTP itself is accurate to a couple of ms under good conditions, and as both servers are in the same environment, they should (presumably) achieve a similar level of accuracy, and so should have a time discrepency between them of a only few ms - but how can I check this?
