• IPv4 not enabled in Windows 7

  - by RidDeBakTiYar

  I have a Netbook with Win 7 Starter edition. I am not able to get IPv4 enabled/installed in the Netbook and hence not able to network/connect to Internet. It says "Limited access" when I check connections. It all began when my system crashed and I was not able to get thro beyond the boot screen. The system advice me to try repair with the original OS cd and I did the same. After that the Netbook has booted, but is not able to network. On a detailed study I found that the Network adapter has both IPv4 and IPv6 Protocols, but there are some differences. The IPv4 is not having the "Properties" enabled to configure, while the IPv6 is having "Properties" enabled. I have only a IPv4 Wired and Wireless at home and its not able to get the Netbook connected as it cannot I had tried uninstalling the Adapter to allow windows to automatically detect and install. Using the "netsh" command to uninstall and install, but not having any change in status. There is a option to "Have disk" under add Protocol, but I don't know how to give the standard IPv4 for installation (asking for *.inf). Any help in solving the issue will be very much appreciated

• Google Chrome mouse wheel takes keyboard focus

  - by Steve Crane

  I recently switched the default browser on all my machines from Firefox to Google Chrome. In general I’m loving Chrome but there is one behaviour that is driving me nuts. Scrolling with the mouse wheel takes keyboard focus away from the document. Here’s what happens. I’ve just opened a page or switched to a new tab and the page has keyboard focus as I can use the keyboard up/down and PgUp/PgDn keys to scroll it; no problem there. But if I then use the wheel on my mouse to scroll the page, it loses the keyboard focus and no longer responds to up/down, PgUp/PgDn, or in fact any other keyboard keys. I have to click on the page background to restore the keyboard focus. This is a minor inconvenience for scrolling but where it really drives me nuts is in Google Reader and Gmail where I use keyboard shortcuts a lot. Here I find that I scroll the article or e-mail I’m reading with the mouse wheel then get no response when I press j/k to move to the next or previous article or e-mail. I am using Windows 7 and the Chrome dev channel (version 4.0.249.43).

• Failed to open the Parallels networking module

  - by user49204

  I'm running Parallels Desktop 7 on OSX Lion and encounter the issue in the subject on every time I'm trying to launch Parallels VM. The error message contains a hint to restore to network configuration default which does not help.

• Windows 7 AIK help

  - by microchasm

  I've just got in a few Windows 7 (64, Windows 7 Professional) machines, and I'm trying to get the AIK 2010 working. I've set up one of the machines, and installed AIK and MDT on it. I've followed the directions at http://technet.microsoft.com/en-us/library/dd349348%28WS.10%29.aspx about 3 times now, and also tried the built-in .chm help files that came with AIK. In AIK I grab the install.wim image off the OEM cd, at which point it asks me which version (I select Professional). I follow the rest of the instructions creating a new Autounattend answer file, and fill in the various bits and pieces according the the step-by-step guides. I verify the Answer file (No warnings or errors), save it, and copy it onto a USB drive. I go to another machine, insert it's OEM Win7 Disk, and power on. I've set BIOS to boot from CD, so it goes directly into the installation. Once The files are loaded, and Setup starts, it immediately asks which version to install (Home basic, Home Premium, Professiona, Ultimate). Ugh, I thought it was supposed to be an automated install, and that selecting the Version when opening the .wim file would answer this question. I looked for an option to set which version to be installed on the net, in the help, and in AIK itself; to no avail. Anyway, just for laughs I select Professional,and hit continue. It copies files for about 10 seconds, then fails with the following error: "Setup was unable to create a new system partition or locate an existing system partition. See the setup log files for more information. [OK]". Clicking OK reboots the box, and obviously there are no log files because the OS isn't installed. It is a Dell Optiplex 380 , Intel Core Duo 2.93 GHzl 4 GB RAM, 64 Bit. Any help would be REALLY appreciated.

• What is the advantage of not running as root? [closed]

  - by Shmuel Brill

  Possible Duplicate: What's wrong with always being root? All modern brands of Linux highly discourage (or disable) one from running as root instead of a normal user. I do not understand why. As a "normal" user, one could Download a rouge program from the internet. Run it (After all, one isn't root, what can it do). It installs itself in .bashrc or .xinitrc It writes a rouge "sudo" and "su" and adds . to the path Not noticing that . is in path, one runs sudo. The rouge program now has root password and can do anything it wants in the system. Even if 3-6 doesn't happen, the program could still Be part of a botnet. Read all files in the home directory and send them back (mine for SS#, Credit Card numbers, bank account numbers, etc). Send spam. Run a backdoor server to allow an attacker a chance to connect to the machine to determine vulnerabilities. It seems that the whole "permissions" thing (root/non-root) is just to prevent amateur crackers from getting into the system, so the question is: Is there a point in avoiding running as root, and is there a way to protect oneself if one wants to run unsafe code?

• Backup server (OSX) like time machine to backup remote ubuntu 12.04 server [on hold]

  - by Mad

  I've searched my ass of for an good solution to backup my ubuntu server thats in a datacenter. Local we have an osx server with some external drives attached to it. This is for the local working stations that handle timemachine. What i like to do is fetch the files (or mount the root of my ubuntu server) and make an time machine backup from it. I just have one problem that if my osx server crashes i can't put back the system because it contains not only the osx server but also the ubuntu server from the data center. I've used Back in time on ubuntu to do the exact same thing but this was to Ubuntu (local) from Ubuntu (datacenter). So does anybody has an solution? Here are my requirements: Set time intervals for backups; need to be backed up nightly. Set time intervals for keeping backups; hourly, weekly, monthy etc Able to back up all computers and servers from an offsite location the local osx server (10.9). Manageable from that one location to login with ssh to do rsync or rsnapshot Has a GUI (osx) Act like time machine, backup only the files that has been changed. Restore to a point back in time.

• Solaris: detect hotswap SATA disk insert

  - by growse

  What's the method used on Solaris to get the system to rescan for new disks that have been hot-plugged on a SATA controller? I've got an HP X1600 NAS which had 9 drives configred in a ZFS pool. I've added 3 disks, but the format command still only shows the original 9. When I plugged them in, I saw this: cpqary3: [ID 823470 kern.notice] NOTICE: Smart Array P212 Controller cpqary3: [ID 823470 kern.notice] Hot-plug drive inserted, Port=1I Box=1 Bay=12 cpqary3: [ID 479030 kern.notice] Configured Drive ? .......

NO But can't figure out how to get the format command to see them so I know they've been detected by the system.

• SSH public key authentication -- always require users to generate their own keypair?

  - by schinazi

  I was working with a partner today that I needed to upload files to my server using scp. I have passwords turned off in the server's SSH configuration, so I wanted them to use public key authentication. I generated the keypair for them on the server and gave them the private key and put the public key in the appropriate authorized_keys file. After a bunch of problems with them setting up their job, they finally got a more experienced sysadmin involved on their end, and he scolded me for handling the key generation this way. He said that by giving them a private key generated on my system, I had enabled them to do a brute-force attack against other keys generated on the same server. I even asked him "so if I have an account on a server, and I can log in with a password but I want to automate something and I generate a keypair on that system, does that then give me an attack vector for brute forcing other users' keys?" and he said yes. I've never heard of this, is it true? Can anyone point me to a discussion of this attack? Thanks in advance.

• Qmail Patching Makes me Nervous

  - by JM4

  We have a system running CentOS 5 with Plesk 8.6 and Qmail running. Our primary domain is hosted through Media Temple. When Plesk and Qmail are hosted on a single Dedicated Virtual server, it reads the primary server IP and domain and reports that when sending emails from the system. Our pages are written in PHP so we are using the mail() function. While our email goes out to everybody, several enterprise email domains reject our email because it shows a different originating IP (our primary server IP and domain) than the domain we list in the 'from' address. This is not modifiable. Every domain we own of course does have its own IP as well underneath our primary server IP. I have seen several places online that provide a patch, specifically - which allows Domain Binding: "DomainBindings -- For servers that host multiple domains or have multiple IP addresses assigned to them, it is sometimes useful (or important) to have qmail use a specific IP address for its outgoing mail. By default, qmail uses whatever address the OS chooses for all outbound connections. With this patch, you can specify which address to use. It uses a control file similar to smtproutes to specify the outbound IP address to use, based on the sender's domain (local copy) (pyropus.ca)" Qmail Link First off I do not have netqmail installed so I'll need to find another source, but also I am completely unfamiliar with applying patches to qmail. Will I lose email services if I patch? Is it a simple apply and use process? Will my existing email accounts and data be restored after the patch? I am very, very new to unix/linux so this does make me a bit nervous but I am the only person who can make the change and it is one our company "HAS" to have. Any ideas?

• How do you get Windows 7 to show time remaining in the battery meter?

  - by MrDaniel

  Running Microsoft Windows 7 Home Premium on a HP Laptop. The system tray power meter never shows the time remaining in the system tray. Only really ever show a percentage remaining number as pictured. The windows help documentation on the "battery meter" seems to indicate that it should display a time remaining indicator, is this accurate? How accurate is the battery meter? The accuracy of what the battery meter reports—what percentage of a full charge remains and how long you can use your laptop before you must plug it in—depends on several factors. Most of these factors fall into the following two categories: What you use the laptop for. Because some activities drain the battery faster than others (for example, watching a DVD consumes more power than reading and writing e-mail), alternating between activities that have significantly different power requirements changes the rate at which your laptop uses battery power. This can vary the estimate of how much battery charge remains. Battery hardware and sensor circuitry. Newer, "smart" batteries are equipped with circuitry that calculates the measurements of charge remaining and reports the information to the battery meter. Older batteries use less sophisticated circuitry and might be less accurate.

• Tomato OS: "memory exhausted" running vi .... how to solve?

  - by Sam Jones

  I have set up tomato (shibby) on an asus RT-N66U router. It works great. I loaded up a few pieces, like transmission and optware. I can run vi, but when I run vi it fails with a "memory exhausted" error, and the terminal session hangs. For reference: If I simply start "vi" it runs fine. But if I specify vi I get the memory exhausted error, even if the file I am opening is just a couple of hundred bytes in size (like fstab). I discovered that my swap partition was not properly set up, so I did that. The swapon command now indicates I really do have a swap: [root@MyRouter samba]$ swapon -s Filename Type Size Used Priority /dev/sda1 partition 32900860 0 1 How can I get vi to work? Thanks!

• Folder Redirection Issues - Freezing, Strange Warnings

  - by JCardenas

  I have Folder Redirection set up in a test environment for a couple accounts. I have followed the instructions for setting up the folder security settings here, and I can confirm that folders are created automatically by the system with the correct security settings when a user logs in. The GPO has been configured to automatically move user files up to the redirected folders, and this is working properly. Problems start occurring when a Windows 7 PC is in use. It is rare, but Explorer will lock up when performing a file write operation (move/copy/save from application). This results in the entire system being unusable, with only a hard reset resolving it (Task Manager doesn't start, the "three finger salute" does nothing, apps stop working). The mouse functions, but clicks do nothing. The other issue is that occasionally when copying/creating/modifying files a dialog box will pop up with the message "You need permission to perform this action. You require permission from XYZ\cardenas to make changes to this folder." The folder that was created by copying an existing one has the correct security settings and lists me as the owner. My company will not be implementing Folder Redirection on XP, since we are making a "clean break" with implementing new technologies with the Windows 7 rollout, so this behavior has not been - nor will be - checked for in XP. Thanks in advance for your help!

• Write access from a Windows client via a ZFS SMB, to a file created on the host in OpenIndiana

  - by Gerald Kaszuba

  I've got an OpenIndiana server running ZFS that is shared using a nobody user and group. I don't fully understand Solaris ACL permissions, but I do know Linux style permissions. The client is Windows 8 and the server is OpenIndiana is oi_148. I'm failing to work out how to make write permission work correctly for the Windows client. It is able to make new files, but can not modify files created by the shell in OpenIndiana. When a file ("local file") is created locally as the user nobody in bash, and another file ("smb file") created remotely via SMB (as nobody also), they are quite different in permissions: # ls -V -rw-r--r-- 1 nobody nobody 0 Dec 2 12:24 local file owner@:rw-p--aARWcCos:-------:allow group@:r-----a-R-c--s:-------:allow everyone@:r-----a-R-c--s:-------:allow -rwx------+ 1 nobody nobody 0 Dec 2 12:24 smb file user:nobody:rwxpdDaARWcCos:-------:allow group:2147483648:rwxpdDaARWcCos:-------:allow In bash, I'm able to write to smb file, but vice versa, the Windows client is not able to write to local file. This is confusing to me because it appears that it should allow the SMB client to write to local file, because nobody is the owner and it has a w in the ACL. The sharesmb setting is is fairly boring, although I'm hoping there can something to set in here similar to a umask: sharesmb name=shared,guestok=true How can I make these two work together and have a symmetrical permission system, where both SMB and the local user produce the same permissions? Is there some sort of ACL that can set at the root of the file system to allow all files to be created in a similar manner?

• iSCSI, failover and XenServer

  - by jemmille

  I have an iSCSI fail over implementation setup so if one of my storage units fails the other takes over immediately (it also runs the NFS shares). When fail over occurs, volumes are exported, the IP is switched to the other machine and the targets are reconfigured. The fail over of the storage system itself works just fine. I use NexentaStor for my filer. When I do a test (manual) fail over of my storage the following occurs: Note: I run the admin VM's on NFS and customer based VM's on iSCSI All NFS based VM's remain up and working perfectly through the failover and after All VM 's running on iSCSI eventually report the following: An error about not being able to write to a particular block An error about journaling not working Then the file system goes RO To get the VM's working again I have to do the following: Force shutdown of the "broken" VM's. Detach the iSCSI SR Re-attach the iSCSI SR Boot the VM on a different server (5 in my pool) If I don't boot on a different server I get this error "Internal error: Failure("The VDI <uuid&gt; is already attached in RW mode; it can't be attached in RO mode!")" The only way I have found to fix that error is to reboot the entire server it was running on previously which is obviously a huge pain. Currently multipathing is NOT enabled (but can be and the same thing still occurs). I have edited much of the /etc/iscsid.conf file to work with the timeout settings but to no avail. In short, my storage fails over properly but XenServer does not keep the connection alive. As a thought, the error that shows up in #4 above might be the ultimate cause and fixing that would fix everything? Any help would be appreciated more than you know.

• IIS 7.0 404 Custom Error Page and web.config

  - by Colin

  I am having trouble with a custom 404 error page. I have a domain running a .NET proj with it's own error handling. I have a web.config running for the domain which contains: <customErrors mode="RemoteOnly"> <error statusCode="500" redirect="/Error"/> <error statusCode="404" redirect="/404"/> </customErrors> On a sub dir of that domain I am ignoring all routes there by doing routes.IgnoreRoute("Assets/{*pathInfo}"); in the .NET proj and I want to put a custom 404 error page on that and any sub dir's of Assets. The sub dir contains static content like images, css, js etc etc. So in the Error Pages section of IIS I put a redirect to an absolute URL. The web.config for that dir looks like the following: <system.webServer> <httpErrors> <remove statusCode="404" subStatusCode="-1" /> <error statusCode="404" prefixLanguageFilePath="" path="http://mydomain.com/404" responseMode="Redirect" /> </httpErrors> </system.webServer> But I navigate to an unknown URL under that dir and yet I still see the default IIS 404 page. I am also seeing an alert in IIS that reads: You have configured detailed error messages to be returned for both local and remote requests. When this option is selected, custom error configuration is not used. Does this have anything to do with the customErrors mode="RemoteOnly" in the site web.config? I have tried to overwrite the customErrors in the sub dir web.config but nothing changes. Any help would be appreciated. Thanks.

• Fixing partitions and Installing BackTrack

  - by Josh

  My whole problem started when I started trying to install Backtrack(3 or 4) Backtrack was trying to install itself over my entire windows partition (Which I had combined into one when I installed windows 7). So I booted back into windows 7 on my netbook (eee pc 1000 HE btw) I went into disk-manager with the aim of making a partition to install backtrack on but came out with a really screwed up drive. So I had two partions when I started: the windows system partition, and then my main partition and they were blue in diskmanager (I think that has something to do with formatting). After I went through the steps to make a 10 GB FAT32 partition for backtrack I had about five partitons one called PE: that I have no Idea what it is the windows system file, my main partiton 10 GB unallocated space, and two other partions under 50MB each that are both unused space. And they were all converted to simple volumes (Green instead of blue). And backtrack still wants to erase my entire drive. Question number 1: How do I get it back to the way it was? Question 2: How to I get backtrack to dual boot on my netbook?

• Web Deploy 3.0 Installation Fails

• Xen dom0 reports incorrect amount of RAM with dom0_mem set

  - by xen_amnesiac

  I've done a fair bit of searching about this, but have found nothing that answers my question. I have a system with 6GB of RAM which acts as a Xen server. For reference, it runs Ubuntu 12.04. I've set the kernel parameter dom0_mem:512M,max:512M in /etc/default/grub as follows: GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=min:512M,max:512M" I've tried variations of that, with the same result. My question is this: With the above set, the dom0 reports in all applications a RAM amount of 422M. cat /proc/meminfo gives the following: $ cat /proc/meminfo MemTotal: 432472 kB MemFree: 54144 kB Buffers: 17640 kB Cached: 220104 kB SwapCached: 30172 kB Active: 136500 kB Inactive: 167780 kB Active(anon): 6156 kB Inactive(anon): 60516 kB Active(file): 130344 kB Inactive(file): 107264 kB Unevictable: 52 kB Mlocked: 52 kB SwapTotal: 1794044 kB SwapFree: 1682012 kB Dirty: 0 kB Writeback: 0 kB AnonPages: 39572 kB Mapped: 8048 kB Shmem: 136 kB Slab: 44324 kB SReclaimable: 22012 kB SUnreclaim: 22312 kB KernelStack: 1280 kB PageTables: 3840 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 2010280 kB Committed_AS: 329192 kB VmallocTotal: 34359738367 kB VmallocUsed: 313988 kB VmallocChunk: 34359417340 kB HardwareCorrupted: 0 kB AnonHugePages: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 524696 kB DirectMap2M: 0 kB top, htop, free -m, and byobu's RAM monitor all report the same amount. At first I thought this was because of the onboard graphics borrowing some memory, but have now switched to a dedicated GPU and it persists. Is this normal behavior, or has something gone amiss? It's just about 100MB of RAM that's "gone", and I have no idea where it went. I understand that it's normal that not all RAM is available for allocation, but does the system really take an amount relatively high to the amount of RAM available?

  Hi folks, I'm trying to configure my IIS7 compression settings in my web.config file. I'm trying to enable HTTP 1.0 requests to be gzip. MSDN has all the info about it here. Is it possible to have this config info in my own website's web.config file? Or do i need to set it at an application level? Currently, I have that code in my web.config... <system.webServer> <urlCompression doDynamicCompression="true" dynamicCompressionBeforeCache="true" /> <httpCompression cacheControlHeader="max-age=86400" noCompressionForHttp10="False" noCompressionForProxies="False" sendCacheHeaders="true" /> ... other stuff snipped ... </system.webServer> It's not working :( HTTP 1.1 requests are getting compressed, just not 1.0. That MSDN page above says that it can be used in :- Machine.config ApplicationHost.config Root application Web.config Application Web.config Directory Web.config So, can we set these settings on a per-website-basis, programatically in a web.config file? (this is an Application Web.config file...) What have i done wrong? cheers :) EDIT: I was asked how i know HTTP1.0 is not getting compressed. I'm using the Failed Request Tracing Rules, which reports back:- DYNAMIC_COMPRESSION_START DYNAMIC_COMPRESSION_NOT_SUCESS Reason: 3 Reason: NO_COMPRESSION_10 DYNAMIC_COMPRESSION_END

• MySQL binlogs seems incomplete?

  - by warl0ck

  I created a Database, a table and inserted some data, and found this binlog.0000001 in my log folder, but when I do mysqlbinlog binlog.0000001, it only shows stuff below, seems incomplete: (There's only two files in the log dir: binlog.000001 binlog.index) /*!40019 SET @@session.max_insert_delayed_threads=0*/; /*!50003 SET @OLD_COMPLETION_TYPE=@@COMPLETION_TYPE,COMPLETION_TYPE=0*/; DELIMITER /*!*/; # at 4 #120924 21:12:56 server id 1 end_log_pos 107 Start: binlog v 4, server v 5.5.24-0ubuntu0.12.04.1-log created 120924 21:12:56 at startup # Warning: this binlog is either in use or was not closed properly.

How do I force close the log? EDIT After flush logs command, I see "0 rows" affected, and a few new files, binlog.000001 binlog.000002 binlog.000003 binlog.000004 binlog.index, the contents are nearly the same as binlog.000001. Now I dropped the database, and try restore it with mysqlbinlog binlog.0* | mysql -u root -p, but the database wasn't recovered.

• Need clear steps on how to convert a Windows 2000 Server to a XenServer VM

  - by Jay

  The source system is not local. The target host running XenServer is not local. The source system is running Windows 2000 Server SP4 and has 1 disk split into 6 partitions, all NTFS: C: 6 GB (boot) D: 15 GB E: 6 GB F: 6 GB G: 5 GB H: 26 GB Most of the partitions are mostly mostly full ( 60%). What is the most straightforward way to do a P2V migration of the server? I can do minor database & data syncs after the P2V is successful & running as a VM within XenServer, it's just getting to that point which is not clear. The option of installing a Windows 2000 Server from scratch is not available, I need to convert the existing physical server as-is into a VM to be hosted within a XenServer environment. I've looked at XenConvert but it maxes out on converting only 4 partitions in one shot, and I'm not certain how to account for the 2 extra partitions. I'm not familiar with XenServer but it's my only option right now to go P2V.

• Windows Server 2008 R2 SP1 Drivers Missing Would Not Install?

  - by bleepzter

  I am building my dev machine with WS2008R2SP1. I consider Windows Server as the best development environment for C# since I tend to focus on server-centric (integration) applications. The desktop flavor of Windows (7) doesn't play nicely with things like Commerce Server or BizTalk... so I to like stick to the environment I develop for. Previously I used to develop inside of VM's but I've found that it is super inefficient and tends to take a toll on the laptops. (I've gone through two of them in 6 months). Problem is that I multiple devices that do not want to be recognized by Windows: My machine is Dell Precision M4500: Intel Core i7-Q740, 1TB HDD, 8GB RAM, Dell re-branded Broadcom DW1501 802x11n Half-Mini Card, Dell re-branded Broadcom DW375 Bluetooh Module, Intel 82577LM Gigabit Network connection NVidia Quadro FX1800 Graphics The devices in question are the Dell rebranded broadcom network and bluetooth adapters: Broadcom USH: USB\VID_0A5C&PID_5800&REV_0101&MI_00 USB\VID_0A5C&PID_5800&MI_00 DW375 Bluetooth Module USB\VID_413C&PID_8187&REV_0517 USB\VID_413C&PID_8187 When I ran the broadcom installers I get "Operating System not supported" which I think is a big oversight on Broadcom's part. Why check for system version string? UGHGHGH Moreover if I try to manually force the driver in windows... I get an error: Driver Management concluded the process to install driver FileRepository\btwampsecfl.inf_amd64_neutral_d8fc2b85d035ed47\btwampsecfl.inf for Device Instance ID USB\VID_0A5C&PID_5800&MI_00\7&66DE6C9&0&0000 with the following status: 0xe0000217. '- or - Driver Management concluded the process to install driver FileRepository\btwampfl.inf_amd64_neutral_d4c4acf036c61299\btwampfl.inf for Device Instance ID USB\VID_413C&PID_8187\90004EEEF5A6 with the following status: 0xe0000217. I googled the 0xe0000217 error code and it says Bad service install section in the driver inf file... Any ideas on how to fix this? I also tried the post by BetaIQ on MSDN Forum, unfortunately the links to the driver package included in the post were dead :( PS. On a side note I also do mobile development for Android, iOS, and Windows Phone, and BB. Having the bluetooth is quite useful with mobile devices.

• DIY NAS - links for Instructions

  - by Kaushik Gopal

  Good folk of SU, I'm planning to build a NAS (Network Access Storage). I'm planning to do it cheap (:read Old PC Config + Open source software). I was looking for good DIY links . Before you shoot this down as a Repost, I'm only looking for good links containing detailed instructions for setting up a NAS. I did a fair bit of searching and found these links (so please suggest others. While these links are great they delve more on the hardware side, i'm looking for more instructions in the software side). For the sake of the interwebs: Ubuntu: http://snarfquest.com/wiki/index.php/Setting_up_a_Home_NAS http://www.smallnetbuilder.com/content/view/27962/77/ http://jonpeck.blogspot.com/2006/11/how-to-configure-80-fileserver-in-45.html FreeNAS http://www.smallbusinesscomputing.com/webmaster/article.php/3719706 http://www.codeproject.com/KB/system/homemade_nas.aspxhttp://www.codeproject.com/KB/system/homemade_nas.aspx There was one at rubbervir.us that everyone points to, but apparently the site has gone down. A couple of other queries: Is Printer/Scanner sharing a possibility with NAS devices? Many talk of torrent support with NAS Devices, a little more light on this? Does this mean, an auto download of torrent through a feed into NAS, or just support for storing Torrent download files onto the NAS(don't see the difference between the latter and a normal file tranfer)

• Video card not detected on Lenovo T410 in Linux

  - by wich

  I have a T410 with an nVidia NVS 3100M, this is not a hybrid system, there is no Optimus. (No option in the BIOS for Optimus, lspci in linux as well as the Windows device manager only show the nVidia) Using lspci I see the GPU as a present device, however, I can not, for the life of me, get any video driver to work that will let me start an X session, every time X craps out with the error (EE) No devices detected. I have tried the nVidia binary blob, (with nvidia-config, made sure no nvidia support in the kernel), I have tried nouveau, I have tried nv, I have even tried generic vesa, nothing will work. When I compare the dmesg that I get when loading the nvidia kernel module, I see that it is missing some lines compared with another system that also has an nvidia card, specifically the line mentioning the GPU name (3100M) is not there. I have checked every option in the BIOS, there is nothing to control except for the BIOS video output port, which is set to the LCD panel. I have no idea anymore what the problem may be, or even how I can diagnose this problem further. Any help will be appreciated.

• Prestashop is not saving Memcached settings

  - by ianenri

  I have a issue with the admin site of prestashop. I'm trying to activate the caching system but it doesn't save the setting. When I add a server (I'm using an Amazon ElasticCache server) saves it, but when I select the enable option and click Save, it redirects me to "Back Office Preferences Performance" but with a blank page and the admin tabs visible. I go back to those settings again and i see that the caching option is disabled. Also, there is a warning: "To use Memcached, you must install the Memcache PECL extension on your server. http://www.php.net/manual/en/memcache.installation.php" , even if i already installed memcached via yum. I tried also, by modifying the settings.inc.php file editing define('_PS_CACHE_ENABLED_', '0'); to: define('_PS_CACHE_ENABLED_', '1'); But i get 500 Internal Server Error in every page, so i prefer to leave it as before. Any ideas? I'm using PrestaShop 1.4.6.2 with Nginx 1.0.11 and PHP-FPM 5.3.8 in a CentOS 5.7 system.
