• PHP + MYSQL site perfomance

  - by Diego

  I have to manage a site which wasn't developed by me. It is in PHP using a mysql database, which is located in the web server. The site, sometimes (when the visitors increase too much) stops responding, or respond too slow. I have developed some sites in PHP but never took care of the management so really don't know where to start. The server (the hard) seems to be fine, when the web stops responding the cpu is being used at about 55% and has a lot of memory. I'm not asking someone to solve this issue. I only would really like if someone could give me a few tips about where can I find logs and how should I read and interpret them. So, that way I would be able to know if its the net traffic, the database (which queries), or what. Thanks! Update: Forgot to say: it is a Windows Server 2003. Note: I've recorded about a day with Jet Profiler. I don't really understand all the information it provides but there is one query which it marks as really slow. It makes sense because it is a select with a where clause which has three like condition. Initially I didn't include this in my question because when I run the query from MySQL Query Browser it doesn't take any long. It is under 0.01 seconds.

• Scheduled task does not run on WIndows 2003 server on VMWare unattened, runs fine otherwise

  - by lnm

  Scheduled task does not run on Windows 2003 server on VMWare. The same setup runs fine on standalone server. Test below explains the problem. We really need to run a more complex bat file, but this shows the issue. I have a bat file that copies a file from server A to server B. I use full path name, no drive mapping. Runs fine on server B from command prompt. I created a task that runs this bat file under a domain id with password that is part of administrator group on both servers. Task runs fine from Scheduled task screen, and as a scheduled task as long as somebody is logged into the server. If nobody is logged in, the task does not run. There is no error message in Task Scheduler log, just an entry that the task started, bit no entry for finish or an error code. To add insult to injury, if the task copies a file in the opposite direction, from server B to server A, it runs fine as a scheduled unattended task. If I copy a file from server B to server B, the task also runs fine unattended, I recreated exactly the same setup on a standalone server. No issues at all. I checked obvious things like the task has "run only as logged in" unchecked, domain id has run as a batch job privilege and logon rights, Task Scheduler service runs as a local system, automatic start. Any suggestions?

• 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?

• Data recovery on a corrupted 3TB disk

  - by Mark K Cowan

  Short version I probably need software to run a deep-scan recovery (ideally on Linux) to find files on NTFS filesystem. The file data is intact, but the references are no longer present. Analogous to recovering data from a "quick-formatted" partition. Hopefully there is a smarter way available than deep-scan, one which would recover filenames and possibly paths. Long version I have a 3TB disk containing a load of backups. Windows 7 SP1 refused to detect the disk when plugged in directly via SATA, so I put it on a USB/SATA adaptor which seemed to work at first. The SATA/USB adaptor probably does not support disks over 2.2TB though. Windows first asked me if I wanted to 'format' the disk, then later showed me most of the contents but some folder were inaccessible. I stupidly decided to run a CHKDSK on my backup disk, which made the folders accessible but also left them empty. I connected this disk via SATA to my main PC (Arch Linux). I tried: testdisk ntfsundelete ntfsfix --no-action (to look for diagnostically relevant faults, disk was "OK" though) to no avail as the files references in the tables had presumably been zeroed out by CHKDSK, rather than using a typical journal'd deletion). If it is useful at all, a majority of the files that I want to recover are JPEG, Photoshop PSD, and MPEG-3/MPEG-4/AVI/MKV files. If worst comes to worst, I'll just design my own sector scanner and use some simple heuristic-driven analysis to recover raw binary blocks of data from the disk which appears to match the structures of the above file types. I am unfamiliar with the exact workings of NTFS but used to be proficient at recovering FAT32 systems with just a hex-editor, so I can provide any useful diagnostic information if you let me know how to find it! My priorities in ascending order of importance for choosing the accepted answer: Restores directory structure Recovers many filenames in addition to the file data Is free / very cheap Runs on Linux Recovers a majority of file data The last point is the most important, but the more of the higher points you match the more rep you'll probably get :)

• Rename a Network Printer win Win 7

  - by Alex

  Seems this is a common question but the answers regularly miss the point. I have a server. Server has some printers connected. Server has all drivers for x32 & x64 OS PLUS ALL DEFAULTS set. Server also manages print queue. I have many workstations, all need to use the printers. All NEED to have drivers print queue and DEFAULTS propagated from server. Now.... When I add the printers on the workstations, I get: "ABC Printer on SERVER123" I need something less long - just "ABC Printer" So how? Tip: Please don't show me how to change the name of your locally installed printer. I know how to do this - I am particularly interested in shared printers that look like "ABC Printer on SERVER123" Tip: Installing the driver with a local port wont cut it because then I loose the server propagated defaults, the driver updates and I need to run around with driver disks/confuse trembling users with hard things like choosing drivers. I am happy for a hack if there is no official way to do this in the group policy.... I tried looking in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Printers on the workstation machines but those are only local printers :( I can see the network printer details on the workstations here: HKEY_USERS[Some GUID]\Printers\Connections But there is nothing obvious like a description string... Can anyone help with this?

• What causes Windows Media Player on Windows 8 to not play the entire library?

  - by somequixotic

  Behavior 1: Verify that the WMP playlist is clear of all songs. Turn on the "Shuffle" and "Repeat" features. Double-click on a music track in the Library. Click the "Next" button (double right angle brackets). A random song from any track in the Library is randomly chosen and played. When observing the Playlist (clicking the "Play" tab), the entire contents of the Library appears in the Playlist. Behavior 2: Verify that the WMP playlist is clear of all songs. Turn on the "Shuffle" and "Repeat" features. Double-click on a music track in the Library. Click the "Next" button (double right angle brackets). The button visually depresses like it has registered the click, but nothing happens. Absolutely nothing. Moreover, the "Previous" button is grayed out. When observing the Playlist, only the one song that was double-clicked appears in the Playlist. What causes Behavior 2? I cannot correlate any specific action I've taken with Behavior 2, and Behavior 1 has been the case as long as I can remember, all the way back to Windows XP. Even earlier during my usage of Windows 8, I recall Behavior 1 working correctly. But suddenly, inexplicably, without changing any settings in WMP, Behavior 2 kicked in, and persists after reboots. I've tried sfc /scannow in an administrator prompt. All system files are in order. I've downloaded all Windows Updates and driver updates. I've attempted to alter WMP options and playback settings to no avail. So... what is causing Behavior 2? Is this an intended, valid behavior, or is something malfunctioning? How would I know what that "something" is? How would I go about fixing it without just reinstalling Windows 8 fresh?

• why adding router will hide all share folders

  - by user1285419

  I have several computers running winxp installed in my office, they are all connecting to the WAN providing by the building (wall socket) (DHCP, mask 255.255.252.0). I setup a shared folder in my computer so all other computer in the same group could access it. This configuration have been using for long time. Recently, I am trying to setup a router. I have the WAN port of the router go to the wall socket, connect the NIC to the LAN port of the router, setup the router in DHCP mode (192.168.0.100/255.255.255.0 to 192.168.0.110 /255.255.255.0), I turn off all the firewall (windows one and router's builtin one), the NIC has ip set as DHCP. If I ipconfig/all, I see that the NIC was assigned ip 192.168.0.100. I can access the internal, email whatever. However, the shared folder can no longer be accessed by other computers in the same group. I think it is the problem of ip. But what's really weird is if I turn off the DHCP function in the router, ipconfig/all always give 0.0.0.0/255.255.255.255 and I cannot access the internet. I have no idea what's going on. Anyone know how to fix it and allow the shared folder in application of router? Thanks.

• Problem configuring php-fpm with nginx

  - by Nisanio

  First of all: I'm not an expert in configuring things. This is very new for me, so, my apologies in advance. At work we have a Centos server. The guy who worked here before installed nginx. We need to made a php site, so, obviously, I need to set up php and make it work with nginx. Making short a very long tale, I had to replace the nginx binary with a new one (because the older was compile without fast-cgi), and I had to recompile and install php (because the new version has fpm). Then I struggle with the config files, making this nginx.conf (not all the file) user php; location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; include fastcgi_params; } and uncomment some parameters in php-fpm (to much to detail here, but the important is that group and user are "php") I never could start the php-fpm with the instructions of the book sudo /usr/sbin/php-fpm start But after look at the net, I found this sudo /usr/local/sbin/php-fpm --fpm-config=/usr/local/etc/php-fpm.conf This worked (I think) I restarted nginx. But... nothings happens with php... My calls to php files (via firefox) doesn't even appear in the log (/opt/nginx/logs/error.log) I'm really, really exhausted and lost... Could anyone help me, pleaaase.... :( Thanks in advance

• HP LaserJet 2550 has a carousel motor error

  - by Arlen Beiler

  I have a LaserJet 2550, and it's worked pretty good for a long time (except for some slowness a while back, spooling I think), but just recently it suddenly quit working. We moved this summer, but left it at our other place, and just recently when my Dad went over there to try to print something out, it didn't work. When you turn it on, you hear the fan give a false start (basically a quick pulse), and the carousel goes through its usual thing. Then it starts up in earnest like it's getting ready to print something. All of a sudden it just stops. Everything stops, and the three lower lights are steady. When I push the Go button, the Go light (bottom of the 3) turns off, but the other two stay on. I looked it up on the HP website and it says it is a carousel motor problem. I called HP, but they said it is out of warranty. I've opened the cover and held the switch with a screw driver so I could watch it, and it goes through its thing like I described (doesn't seem to make a difference whether the imaging drum is in or not), then when it stops it kind of seems to jump back a little bit (the carousel). I hope this all makes sense (I know you like details), and hopefully you also know what to do to fix it. Thanks.

• I can't download or stream for more then 3 sec, and then the conection activity just dies

  - by JMHein

  Just got a new internet connection installed at my sisters place, but it randomly just stops working. At first it was only affecting flash videos. they would randomly just stop buffering. I did a lot of research on this and found that there can be many things that cause this exact trouble. I then tried IE and some flash would stream fine, but still random deaths. So I told my brother in law to reset the router and modem and that fixed the problem for them but not my laptop. I then started trying to fix the flash problem only to fined that downloads of any kind were affected. Now it is so bad that 50% of page loads will never finish because the connection drops to 0% usage with in a split sec. I can't get flash reinstalled because the installer is trying to download but the download dies at 8% I tried up loading a large file by FTP to a web server with no troubles. Yet any activity on my end that takes longer then about 1 sec to finish, just never finishes I can watch the network log in the taskmanager and it spikes for ruffly one sec then drops back to zero and when I go back to the web page it says it is still loading and no matter how long I let it sit it never does any thing more till I reload then it will again create a very short spike of activity on the connection and then drop to zero. Also if I start a download and it does drop off I can restart the download where it left off and get up to 100Kb/s for around the same one sec then it drops to around 14Kb/s then zero a sec latter... I am running Win 7 home prem x64 with FF11 and IE8 I have simply tried every thing I can short of calling up the ISP which very likely will get me no where fast. any advice on what step to take to figure this out would be nice. I am not even sure it is not just an ISP problem. (at least I should be able to get flash reinstalled once I get back home)

• Networking problems in VMWare with wireless bridge

  - by Robert Koritnik

  Barebone data: virtualization: VMWare Workstation 6.5 (latest) Host: Windows Server 2008 x64 Guest: Windows Server 2008 x86 Host network adapter: wireless Guest network adapter 1: over Bridge VMNet (automatic) Guest network adapter 2: over Host only VMNet Problem When I surf the net within VM my internet connection just gets stalled (not dropped). It doesn't experience any timeout whatsoever, it just stops downloading/communicating. For instance: I start downloading a file with a browser (IE/FF/CR doesn't matter) and I have to pause/restart download when speed drops to 0. I could wait indefinitelly but connection won't pickup automatically. What did I miss in my network configuration? Update 1 I've tested this in various combinations. This works fine when host is connected via Ethernet. But when connected via Wifi, the connection on the guest works as previously described. It connects fine. It gets a valid IP from DHCP... Everything is cool as long as you don't start doing some intensive network traffic (ie. download a 2MB file) In this case it starts downloading and stops after a while. Speed just drops to 0B/s... Sometimes it picks up back, sometimes it doesn't. Connection still stays and works. I can ping around with no problem.

• CopSSH SFTP -- limit users access to their home directory only

  - by bradvido

  Let me preface this by saying I've read and followed these instructions at the FAQ many times: http://www.itefix.no/i2/node/37 It does not do what the title claims... It allows every user access to every other user's home directory, as well as access to all subfolders below the copssh installation path. I'm only using this for SFTP access and I need my users to be sandboxed into only their home directory. If you know a fool-proof way to lock users down so they can see only their home directory and its subfolders, stop reading now and reply with the solution. The details: Here is exactly what i tried as I followed the FAQ. My copSSH installation directory is: C:\Program Files\CopSSH net localgroup sftp_users /ADD **Create a user group to hold all my SFTP users cacls c:\ /c /e /t /d sftp_users **For that group, deny access at the top level and all levels below cacls "C:\Program Files\CopSSH" /c /e /t /r sftp_users **Allow my user group access to the copSSH installation directory and its subdirectories For each sftp user, I create a new windows user account, then I: net localgroup sftp_users sftp_user_1 /add **Add my user to the group I've created Open the activate user wizard for CopSSH, choosing the user, "/bin/sftponly" and Remove copssh home directory if it exists **Remains checked Create keys for public key authentication **Remains checked Create link to user's real home directory **Remains checked This works, however, every user has access to every other user's home directory as well as the CopSSH root directory.... So I tried denying access for all users to the user home directory: cacls "C:\Program Files\CopSSH\home" /c /e /t /d sftp_users **Deny access for users to the user home directory Then I tried adding permissions on a user-by-user basis for each users home\username folder. However,these permission were not allowed by windows because of the above deny rule i created at the home directory was being inherited and over-riding my allow rule. The next step for me would be to remove the deny rule at the home directory and for each user folder, add a deny rule for every user it doesn't belong to, and add an allow rule for the one user it does belong to. However, as my user list gets long, this will become very cumbersome. Thanks for the help!

• On a failing hard drive, I am able to view data but unable to copy it - why?

  - by Tom

  I have a 2.5" external hard drive that is failing. It's not making the expected 'clicking' noise that most hard drives and I am able to view the data, but I am unable to actually retrieve the data. I attempted to use SpinRite in order to access the data on the drive, but it didn't like the external drive. When I view the drive's property page, the drive shows that it's used space is at 100% and that it has 0 bytes available; however, the progress indicator under the drive icon in Windows Explorer shows that it's roughly 50% full (which is correct). When I attempt to run Windows' "Error Checking" tool and attempt to "scan for an attempt recovery of bad sectors," the tool begins to run then immediately closes with no error message. I am able to browse the contents of the drive using Windows Explorer. When I begin to try copying any given single file, the copy process begins, an indicator starts, and then the copy fails with no real error message. The Disk Management page in Computer Management under Control Panel also shows this drive has being 'Healthy.' I dropped the drive off at a data recovery store and they said that "The data seems to be intact, but an internal failure is preventing any information from being retrieved." They offered to provide me references to a data recovery specialist. I've also attempted to run CHKDSK on the drive (with and without arguments) but it returns the following error: The type of the filesystem is RAW. CHKDSK is not available for RAW drives. Before going the route of more expensive data recovery, I'm wondering if these symptoms sound familiar to anyone? Other questions... I'm willing to continue trying tools such as TestDisk and/or PhotoRec (as the majority of the data that I'd like to salvage are photos) but how long I should expect either tool to run given approximately 400GB of data? I'm also comfortable using Linux so I welcome any suggestions for utilities or tools and strategies with which you've had success.

• Numeric UIDs/GIDs in ACLs on OS X server (10.6)

  - by Oliver Humpage

  Hi, On one (old OS X 10.4) server I'm tarring up some files which have ACLs. I'm then using ``tar -xp'' to untar the archive onto a new 10.6 server, which doesn't have any users/groups configured on it yet except the default admin (UID 501) (there's a reason for that, don't ask!). Obviously this means an "ls -lne" will list files and ACLs with numeric UIDs and GIDs. Now for the normal file permissions it makes sense: you get UIDs like "1037". And for some ACLs, it also makes sense: you get things like "AAAABBBB-CCCC-DDDD-EEEE-FFFF00000402" for groups (0x402 = GID 1026) and "FFFFEEEE-DDDD-CCCC-BBBB-AAAA000001F5" for users (0x1F5 = UID 501). However, some ACLs have a UIDs like "E51DA674-AE70-41BC-8340-9B06C243A262" or GIDs like "0A3FCD24-0012-46FA-B085-88519E55EF29" and I have absolutely no idea how to translate these IDs back into something that could be matched back to the original IDs (UID 1072 and GID 1047 respectively in this example). Can anyone help me translate these weird long hex strings? (Basically we're moving from local users to an Active Directory setup, so I want to move all files to the new server with permissions intact, then chmod, chgrp and set ACLs such that we translate old IDs to the new AD IDs. Hence needing some way to map between the sets. I don't believe there's an easier way to do this?) Many thanks, Oliver.

• Windows CE restores default configuration after restart (Motorola MC3190)

  - by jarek

  Good morning, everyone! I have a problem with Motorola MC3190 hand scanner running on Windows CE. I've got few of those to make a new program for some kind of warehouse. There is already installed program which have been used by the customers before, so I delete this one and instead I install my new software which I've just made. It is running very well, but when I take out the battery and leave the device for entire night without power supply, it restores the whole configuration, so the old program is back, the wireless configuration is back and... Yeah. The scanner is restored to the configuration which was running when I received it few weeks ago. What I want to do is to set the whole configuration of the scanner so after a long power-off my program and my configuration will be restored. I truly believe someone knows how to do it. The time is running out, and I believe that the customer will be kind of annoyed when he will change the battery and the program which he bought will be gone. ;-) Regards, Jarek

• Using two ports on my ZyXel USG gateway to patch two devices together?

  - by Matthew Beza

  I don't know if this is possible but it would save me many long drives! I have drawn, with my epic MS Paint skills, my current setup. I have a ZyXel USG300 Gateway with a built in 5 port switch. It supports bridging, tunnles, VLANs, etc.. I have a Cisco WLC2112 plugged into port 6 (P6). The cisco is set to 192.168.6.2 and P6 is set to 192.168.6.1. This works but I need to incorporate a Nomadix AG3000 to handle guests. (Router (A) in the picture). So I need the Cisco WLC2112 to use the Nomadix as if it where plugged into it's LAN port. Right now the Nomadix WAN Port is plugged into (P2) on the ZyXel, and the Nomadix LAN port is plugged into (P3). Is it possible to set something up where (P3) and (P6) are somehow "Patched" as if the Cisco was plugged directly into the Nomadix LAN port? Basically making the ZyXel a fancy Cat5e coupler?

• Project and Business Document Organization

  - by dassouki

  How do you organize, maintain edits, revisions and the relationship between: Proposals Contracts Change Orders Deliverables Projects How do you organize your projects for re-usability? For example, is there a way to add tags to projects, to make them more accessible? What's a good data structure to dump all my files on an internet server for easy access? Presently, my work folder is setup as follows: (1)/work/ (2)/projects (3)/project_a (4)/final (which includes all final documents) (5)/contracts (5)/rfp_rfq (5)/change_orders (5)/communications (logs all emails, faxes, and meeting notes and minutes) (5)/financial (6)/paid (6)/unpaid (5)/reports (4)/old (include all documents that didn't make it into the project_a/final/ (3)/project_b (4) ... same as above ... (2)/references (3)/technical_references (3)/gov_regulations (3)/data_sources (3)/books (3)/topic_based (each area of my expertise has a folder with references in them) (2)/business_contacts (3)/contacts.xls (file contains all my contacts) (2)/banking (3)/banking.xls (contains a list of all paid and unpaid invoices as well as some cool stats) (3)/quicken (to do my taxes and yada yada) (4)/year (2)/education (courses I've taken (3)/webinars (3)/seminars (3)/online_courses (2)/publications (includes the publications I've made (3)/publication_id We're mostly 5 people working together part-time on this thing. Since this is a very structured approach, I find it really difficult to remember what I've done on previous projects and go back and forth easily. What are your suggestions on improving my processes? I'm open to closed and open source software (as long as the price isn't too high). I also want to implement a system where I can save most of the projects online to increase collaboration and efficiency and reduce bandwidth especially on document editing. Imagine emailing a document back and forth 5-10 times a day.

• Using NginX and Apache alongside for both static and dynamic files

  - by faridv

  Background: I've searched a lot and found these useful threads about using of Apache or NginX for static or dynamic files. But they are old (mostly about 1 or 2 years ago) and I think both webservers, specifically Nginx has had important changes in performance and usage. So I think take another look on these issue cannot be that bad. Nginx (for static files) and Apache (for dynamic content)? nginx better than apache for dynamic content? [closed] Apache or NGINX for PHP? Nginx as reverse proxy to Apache with only dynamic content? My question: I have a PHP web application with lots of dynamic files and lots of static contents (videos, images etc.) and it's currently running on a CentOS 6 server and Apache 2.2 since 2 months ago. In past few days, number of our site visitors have gained so fast and I just thought if this number continues to increase with current ratio, we need to change many things (web server, application, etc.) to prevent failures. Because of hardware limitations that we are facing, I thought that it's best for us to start with web server. Should I start with something else? Should I try to increase performance of my PHP application and forget about web server for now? (even if gonna take a long time!) Because of huge usage of .htaccess files (for redirection, rewrites, etc.), I think it's gonna be painful to migrate to NginX as default web server or maybe only for dynamic files. Does this mean that I can't even use Nginx as reverse proxy? I'm not sure latest stable version of NginX and PHP-FPM have a better performance over my current Apache and my limitations (too many things) won't let me to give it a try. Which one is doing better currently? What will I lose by migrating to Nginx? To make it short, what should I do?

• Acer Aspire One -- strange battery problem, charges only up to ~90%

  - by houbysoft

  I have this strange problem on the acer aspire one d250. It happened already once before, stayed for about two weeks, and then "fixed itself". The problem is as follows: the battery can't seem to get fully charged; ie the indicator is stuck at about 90% (it's probably not a software problem -- I have ArchLinux and Windows 7 installed and both report exactly the same) and it never passes that value, but it still shows the status as "charging" (I tried everything I could think of -- leaving it charging for extremely long amounts of time, doing a few complete charge-recharge cycles, removing/reinserting the battery, cleaning the connectors, even updating the BIOS, etc., and nothing helped). Also, when it is getting charged, it charges pretty fast until about 70% and then progresses extremely slowly. The battery holds the charge that appears on the battery indicator normally. Just can't get the battery to charge fully -- I can't get it past the 90%. At first I thought this would be a simple battery failure (even if the computer is not that old, about 6-7 months), but as I mentioned it happened once before, and then one day it fixed itself. I tried contacting Acer about this, but the support was not helpful, completely stupid, it seemed like they used canned responses, the usual. Any thoughts on how to fix this?

• Officially announced RAM support size doesn't apply to one of twin rigs with just one difference

  - by Deniz

  It'll take a little long to describe my situation but here goes the story : In January 2009 we bought (the OEM parts) two similar systems with just one difference. One of them had a Phenom X4 cpu and the other one (mine) a Phenom X3 cpu. At the beginning we had problems with both systems to power them on whilst having all of their ram slots being full. We decided to install the systems with just 2 slots populated and later try to install the rest of ram sticks. Both systems did succeed to support 3 sticks. We tried many different procedures to make the systems work with their fourth ram slots being populated. We waited for new bios updates and flashed the boards when they were available, we tried different ram sticks with different frequencies etc. One day while we were trying to install the fourth stick, the X4 machine did accept it. The other one did not. The most mind boggling thing was that after one of my trials the X3 system begun to not operate with the third slot populated. Our boards did have AMD 770 chipsets and we even tried to change the board of the X3 machine with another 770 chipset board. Now my questions are : Should we change the cpu ? What is causing the X3 system to not accept the fourth (or now the third) ram stick ? The manufacturers sites do claim that this boards do accept 4 ram sticks (but they only tested them with certain ram brands and models). What are the limitations for maximum ram configurations on motherboards ? Are there some "rules of thumb" except frequency, voltage, chip type considerations for which we did check our parts ? Our boards are : Gigabyte GA-MA770-DS3 Sapphire PC-AM2RX780 - PURE CrossFireX 770

• Is Windows Server 2008R2 NAP solution for NAC (endpoint security) valuable enough to be worth the hassles?

  - by Warren P

  I'm learning about Windows Server 2008 R2's NAP features. I understand what network access control (NAC) is and what role NAP plays in that, but I would like to know what limitations and problems it has, that people wish they knew before they rolled it out. Secondly, I'd like to know if anyone has had success rolling it out in a mid-size (multi-city corporate network with around 15 servers, 200 desktops) environment with most (99%) Windows XP SP3 and newer Windows clients (Vista, and Win7). Did it work with your anti-virus? (I'm guessing NAP works well with the big name anti-virus products, but we're using Trend micro.). Let's assume that the servers are all Windows Server 2008 R2. Our VPNs are cisco stuff, and have their own NAC features. Has NAP actually benefitted your organization, and was it wise to roll it out, or is it yet another in the long list of things that Windows Server 2008 R2 does, but that if you do move your servers up to it, you're probably not going to want to use. In what particular ways might the built-in NAP solution be the best one, and in what particular ways might no solution at all (the status quo pre-NAP) or a third-party endpoint security or NAC solution be considered a better fit? I found an article where a panel of security experts in 2007 say NAC is maybe "not worth it". Are things better now in 2010 with Win Server 2008 R2?

• Remote desktop solution where the desktop sharing party contacts the computer it wants to share with

  - by Kent

  I'm in a situation where I act as a sort of techinical support to my family and less techinically experienced friends. I'm looking for a remote desktop solution where it's possible to setup a "zero-install, double click an icon"-solution where the client computer contacts me so that I may interact with their desktop. The last part is important as the people in need of my help don't know how to configure their router or even the firewall software on their own computer. They are able to click an accept button when asked if a program should be able to make outgoing connections. They have many different kinds of routers, as well as software firewalls, and I rather not deal with the problem of how to connect to them using whatever as well as the actual problem they are having. It must be: Free of charge for non-commercial use. Possible to use it in a mode where the computer wanting to share its desktop should be able to make a connection to my computer. My computer has a DNS name we can use. Compatible with both Windows XP and Windows 7. Independent of a third party server or infrastructure. Explanations of the above: I don't want to spend money on it when I help them for free. If it's free as in freedom, all the better! I guess this boils down to being callable like showdesktopto.exe opscomputer.com where opscomputer.com is my computers DNS name. If that is possible then I can create a shortcut they can use to connect to me when they need help. It's nice if it's possible to specify a password or key file which I can use to authenticate myself, but it's not required. They use the OS which their machine comes installed with. That means Windows XP or 7. I want something which will work in the long run. Using a third party service which might not be available when I need it disqualified such solutions.

• Laptop recommendation - Portable Gaming

  - by ivan

  So, I'm looking for a new laptop (http://superuser.com/questions/116869/toshiba-satellite-u500-totally-damaged-lcd). My requirements for a new Laptop are: -good keyboard(illuminated) and touchpad (multi-media keys included, should be better than toshiba u500) -good graphics card, with system rating of 6.3 and up for gaming graphics (my Toshiba U500 has 6.3). I used to run some heavy games on my Toshiba U500 with ATI Mobility Radeon 4570 with 512 mb VRAM but the framerates are not that nice on high settings. -Decent CPU but I think all new Core i3, i5, i7 can run most of recent resource intensive games (My Toshiba U500 has a Core 2 Duo T6500, 2.13 Ghz) I'm also looking for a long-term reliability, good sound quality, lots of fast RAM of-course(4GB DDR3 - 1066Mhz and up) and a clear looking LED screen with a decent resolution. (I can accomodate a laptop with screen size of 13-inch upto 15.6 inch, and I don't want it to be heavy because I might be taking it outdoors) I'm actually impressed when I saw HP Pavilion DV6t but the screen resolution seems to be a little too small for 15.6 inch. The Pavilion DV3 are also good but I want to know if there other options. Looking for some opinions.. Thanks. :D

• Change the default route without affecting existing TCP connections

  - by Patrick Horn

  Let's say I have two public network addresses on my server: one NAT through an ISP (192.168.99.0/24), and a VPN through a different ISP (192.168.1.0/24), already configured with a per-host route to the VPN server through my ISP. Here is my initial routing table. I am currently routing through my ISP on subnet 192.168.99.0/24. $ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.99.1 0.0.0.0 UG 0 0 0 eth1 55.66.77.88 192.168.99.1 255.255.255.255 UGH 0 0 0 eth1 192.168.99.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 tap0 Now, I want new TCP connections to switch to my 192.168.1.0/24 so I type the following: $ route add -net 0.0.0.0 gw 192.168.1.1 dev tap0 When I do this, it causes some long-standing TCP connections to hang. Is there a way to I safely change the default interface for new connections, while allowing existing TCP connections to use the old route (i.e. do I need enable some sort of stateful routing table)? I am okay with a solution that only works with established TCP connections, and I don't care how hacky it is. For example, if there is a way to add temporary iptables rules for existing connections to force them over the old route. But there has to be some way to do this. EDIT: Just a note about a simple "route add -host ... " for existing connections: this solution would work if I am fine with leaving a subset of IPs on the old interface. However, in my application, this actually doesn't solve my problem because I want to allow new connections to come on the new interface even if they have the same source IP. I'm now looking at using the "ip route" command to set source-based routing rules.

• Acer Aspire One (mini) mfgd 9/03 locks up also when plugged in

  - by LAURIE ANN

  My problem is almost the same as the Toshiba user (Toshiba A205-5804 freezes when plugged in): Well I have a Toshiba A205-5804 and the problem is that the screen freezes anytime I plug the pc into the external power supply, not as most of the computers having the same issue, my computer DOES freeze in safe mode, and I really can't bear this problem for much longer... It's not an overheat problem, the computer is not getting hot or anything related, I've tried already to change the AC adapter, to boot only with AC and no battery, and also all of these suggestions: The only difference in my case is: I can be using the battery and when it runs down, I can just close the lid and the system goes into hibernation mode. I then plug it in and let it charge. When I think it's finally charged, I can UNPLUG it, open the lid and all is running fine on the battery again. Note: the system was NOT shut down and it still runs as long as I remove the power plug before opening the lid. I have ALL the same issues as the other Toshiba user, also. I was a tech for 9 yrs in my own business and this one has not only stumped me, but anyone I have asked has never heard of this problem. Every repair center wants to charge me for diagnosis, even is they cannot fix it. I would really like to run this system along side of my new Acer Aspire 17" laptop as I need it to finish my grad school work. Any ideas would be GREATLY appreciated. Thanx, Laurie Ann
