  • Combining Two .htaccess files .. Wordpress and OSCommerce SEO URL's

    - by William Langford
    I Googled over and over and got no where so I figured I would give this a try.. I have OSCommerce in my httpdocs directory. Then I have /wordpress but changed the blog location to /blog.php with some mods. Works great. Now to add SEO URL's from Wordpress to my OSC htaccess OSC htaccess; Options +FollowSymLinks RewriteEngine On RewriteBase / RewriteRule ^(.)-p-(.).html$ product_info.php?products_id=$2&%{QUERY_STRING} RewriteRule ^(.)-c-(.).html$ index.php?cPath=$2&%{QUERY_STRING} RewriteRule ^(.*)-m-([0-9]+).html$ index.php?manufacturers_id=$2&%{QUERY_STRING} RewriteRule ^(.*)-pi-([0-9]+).html$ popup_image.php?pID=$2&%{QUERY_STRING} RewriteRule ^(.*)-t-([0-9]+).html$ articles.php?tPath=$2&%{QUERY_STRING} RewriteRule ^(.*)-a-([0-9]+).html$ article_info.php?articles_id=$2&%{QUERY_STRING} RewriteRule ^(.*)-pr-([0-9]+).html$ product_reviews.php?products_id=$2&%{QUERY_STRING} RewriteRule ^(.*)-pri-([0-9]+).html$ product_reviews_info.php?products_id=$2&%{QUERY_STRING} RewriteRule ^(.*)-i-([0-9]+).html$ information.php?info_id=$2&%{QUERY_STRING} Wordpress htaccess RewriteBase /blog.php/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /blog.php/index.php [L] Is this even possible with two RewriteBase files? I looked at a way to do it with directory defines but didn't think it was possible as blog.php isn't a directory. Thanks!

  • Memory Usage of SQL Server

    - by Ashish
    SQL Server instance on my server is using almost full memory available in my Physical Server. Say if i am having 8GB of RAM than SQL Server is using 7.8 GB of RAM from system. I also have read articles and also read many similar questions regarding same on this forum and i understand that memory is reserved and it is using memory. But i have 2 same servers and 2 SQL Servers, why this is happening on a single SQL Instance not on other. Also when i run DBCC MemoryStatus than it is showing up... VM Reserved 8282008 VM Committed 537936 so from this we know that SQL reserved whole 8GB memory, but why this VM Committed keeps increasing. What i understand is VM Committed is: VM Committed: This value shows the overall amount of VAS that SQL Server has committed. VAS that is committed has been associated with physical memory. So this is the memory SQL Server has committed (from this i understand that physical memory actually SQL Server is using at instance). So like to know the reason behind this ever increasing VM Committed memory on my server and not on another. Thanks in Advance.

  • Give access to specific services on Windows 7 Professional machines?

    - by Chad Cook
    We have some machines running Windows 7 Professional at our office. The typical user needs to have access to stop and start a service for a local program they run. These machines have a local web server and database installed and we need to restrict access to certain folders and services related to the web server and database for these users. The setup I have tried so far is to add the typical user as a Power User. I have been able to successfully restrict them from accessing certain folders (as far as I can tell) but now they do not have access to the service needed for starting and stopping the local program. My thought was to give them access to the specific service but I have not had any luck yet. In searching the web for solutions the only results I have found relate to Windows Server 2000 and 2003 and involve creating security templates and databases through the Microsoft Management Console. I am hesitant to try an approach like this as these articles are typically older and I worry this method is outdated. Is there a better way to accomplish the end goal of giving the user permission to run the service and restrict their access to certain folders? If any clarification is needed on the setup or what we are trying to achieve, please let me know. Thanks in advance.

  • Laptop authentication/logon via accelometer tilt, flip, and twist

    - by wonsungi
    Looking for another application/technology: A number of years ago, I read about a novel way to authenticate and log on to a laptop. The user simply had to hold the laptop in the air and execute a simple series of tilts and flips to the laptop. By logging accelerometer data, this creates a unique signature for the user. Even if an attacker watched and repeated the exact same motions, the attacker could not replicate the user's movements closely enough. I am looking for information about this technology again, but I can't find anything. It may have been an actual feature on a laptop, or it may have just been a research project. I think I read about it in a magazine like Wired. Does anyone have more information about authentication via unique accelerometer signatures? Here are the closest articles I have been able to find: Knock-based commands for your Linux laptop Shake Well Before Use: Authentication Based on Accelerometer Data[PDF] Inferring Identity using Accelerometers in Television Remote Controls User Evaluation of Lightweight User Authentication with a Single Tri-Axis Accelerometer Identifying Users of Portable Devices from Gait Pattern with Accelerometers[PDF] 3D Signature Biometrics Using Curvature Moments[PDF] MoViSign: A novel authentication mechanism using mobile virtual signatures

  • Apache, Tomcat and mod_jk for load balancing

    - by pHk
    Hi guys. I've set-up a basic Apache (2.2.x) and Tomcat (6.0.x) set-up using mod_jk for load balancing using the worker.properties file. Preliminary testing seems to show that this works relatively well, and it was quite easy to set-up. However; the fact that it was so easy to set-up has got me a little worried. We're dealing with 100 - 300 concurrent users using the same web application (deployed on 2 or 3 Tomcat instances). I have done a little Googling and looking around on here and there seems to be more than 1 way to accomplish this (one example on here used a balancer:// style URL, which I've never seen before in an Apache config). For example, one question I ask myself is how reliable the load detection on mod_jk really is (Busyness, Session, Request, etc). In your experience, does this set-up prove to be reliable in real world scenarios? Any pointers on improvements, pit falls or interesting literature/articles? I've worked with Apache before, but am in no way an expert. Thanks in advance.

  • How To Investigate/Restore MySQL Permissions? MySQL ERROR 1045 (28000): Access denied for user

    - by Recc
    ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) Debian. mysqld is listening on 3306 supposedly Telnet to 3306 works Also tried binding it specifically yo localhost and then 127.0.0.1 which made no difference However: # netstat -ln | grep mysql unix 2 [ ACC ] STREAM LISTENING 78993 /var/run/mysqld/mysqld.sock # mysql -P3306 -ptest ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES) Things I've tried: dpkg-reconfigure mysql-server-5.1 Doesn't help http://www.debian-administration.org/articles/442 Doesn't help This command (source): UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root'; FLUSH PRIVILEGES; Doesn't help, in fact: Query OK, 0 rows affected (0.00 sec) Rows matched: 0 Changed: 0 Warnings: 0 So might the user be deleted? Extremely unlikely as all this started after packages update a colleague did and some separate services started screwing around but my colleague said he removed the offenders. Theres more: while # mysqld_safe --skip-grant-tables is running one can access the data tables, only with the valid passwords! So there's users and some authentication takes place hence the 0 rows affected above. Can the privileges tables be damaged somehow and how can I recreate/restore them when my only way of getting a mysql console is to skip them? Can I spare my reinstall of MySQL? Either way I did get a dump of the DBs now that I could get in with the above mode.

  • Hosting multiple websites from home

    - by dean nolan
    I have just been accepted for Microsofts Wevsite Spark program which I mainly got for the tools, Visual Studio, Blend. I also have a few of my own websites, personal and a couple of business ones. I also work freelance and sometimes I would like a place to just put a demo up of a clients project. The websites I currently have are all on differnet hosting provders and domain registrars. The WebsiteSpark comes with Windows Server 2008 and SQL Server 2008. It would be really advantagous of me to have all these in one place but also so I have complete control over the database and the environment. So I am thinking over the next 4-6 months of migrating all this to my own server that I will host from home, or maybe even setup at home and then store in a proper datacentre. I was wondering what steps I should take and what to be aware of, specifically: 1) having all these different websites on one computer and having the url got to the proper place. 2) Cost effectiveness? Having the server in home as apposed to datacentre. Most solutions I see charge over £1000 a month to have a machine in datacentre. This is mostly for my own ease of management and shared hosting which I currently have is very limited configuration wise. Would getting a server in house be beneficial for then upgrading to the cloud? What measures should I take with my ISP? I know this is a lot I've asked but just even links to good articles would be good. Thanks

  • Sharing between Vista and Windows 7

    - by Metro Smurf
    Vista Ultimate 32 bit Windows 7 Ultimate 64 bit I've read through similar questions about sharing between Win7 and Vista, but none of them have resolved my issue of not being able to share between Win7 and Vista: Connecting to a Vista shared folder from Windows 7 Networking Windows 7 and Vista Enable File sharing in Windows Vista Previously I had previously had my Vista and XP system sharing back and forth without any problems. I was able to access the shares without entering a user name / password in the NT challenge prompt (note: account names and passwords were different on the Vista and XP systems). Currently I replaced my XP system with a Win7 system. Now, when I attempt to access shares to/from Vista / Win7, I am continually prompted with an NT challenge to enter my credentials. Things I've Verified/Tried Both systems are on the same workgroup. Win 7 is using the Home network. Vista is using the Private network. In other words, neither system is using a Public network profile. Enabled file sharing with and without password protection on both Vista and Win7 Tried HomeGroup Connections (win7) with Windows to manage connections and Use user accounts to connect. Reviewed too many online articles to count to trouble shoot. Set the shares to have full control by everyone. Set up the shares directly on the directory and through the share manager. My Question How can I enable file sharing between Vista and Win7 without being prompted with a username/password challenge, ever?

  • Why database partitioning didn't work? Extract from thedailywtf.com

    - by questzen
    Original link. http://thedailywtf.com/Articles/The-Certified-DBA.aspx. Article summary: The DBA suggests an approach involving rigorous partitioning, 10 partitions per disk (3 actual disks and 3 raid). The stats show that the performance is non-optimal. Then the DBA suggests an alternative of 1 partition per disk (with more added disks). This also fails. The sys-admin then sets up a single disk, single partition and saves the day. The size of disks was not mentioned but given today,s typical disk sizes (of the order of 100 GB), the partitions ; would be huge, it surprises me that a single disk with all partitions outperformed. Initially I suspect that the data was segregated and hence faster reads. But how come the performance didn't degrade as time went by with all the inserts and updates happening? Saw this on reddit, but the explanation was by far spindle/platter centered. There was no mention in the article about this. Is there any other reason? I can only guess that the tables were using a incorrect hash distribution causing non-uniform allocation across disks (wrong partitioning); this would increase fetch times. Any thoughts?

  • ATI Firepro v4800 3 monitor support

    - by Jared275
    I have an interesting, yet very frustrating problem. I have two computers, both running win7 32 bit, and both with ATI Firepro V4800 graphics cards. Both are using the DVI port and two DP to DVI adapters to connect 3 monitors. One of them is able to display three desktops, while the other fails at enabling the third, displaying "cannot save changes" in display properties while requiring that one monitor must be disabled when making the change in CCC. I've verified that both computers have the same driver version and that both are using the same DP-DVI adapters. This articles suggests a few things to try, but none of its suggestions seem to work either. I'm kind of at my wits end, hence my posting here. If this is not an appropriate question for SU, I apologize. I admit that I am not very familiar with the differences between dual link and single link DVI, and that is something I have not verified is standardized between the two computers. Is that a possible reason one is working and the other isn't? How do I check if the DVI cable is a single link, or dual link?

  • What's the mysql-5.5 compilation configuration arguments on Ubuntu 10.04?

Though I've seen these articles: https://wikis.oracle.com/display/mysql/Cmake Building mysql-5.5.19 from source on ubuntu 11.10 with the static flag Compile MySQL 5.5.15 from source using autorun.sh and cmake, unable to start MySQL after Would anyone like to share the mysql-5.5 configuration arguments of compilation on Ubuntu 10.04? $cmake # what arguments to enter for this command update: cmake . -DBUILD_CONFIG=mysql_release -DCMAKE_INSTALL_PREFIX=/path/to/mysql_installation_dir -DWITH_SSL=no the official web site says it need to use cmake to compile the source package, but according to a teck blog, it doesn't need to compile the source, so which one is correct?

  • 'The rpc server is unavailable' or 'access is denied' error when using Remote desktop Services Manager on Windows 7 (but mstsc.exe works!)

    - by tbone
    I am trying to connect to a Windows XP workstation from a Windows 7 Ultimate workstation using Remote Desktop Services Manager. I am able to do a Remote Desktop (mstsc.exe) session from the Win7 machine to the WinXP machine with no problem at all. When running the Remote Desktops Admin (tsmmc.msc) too on a Windows XP box, I can also connect with no problem. However, when I use the new Remote Desktop Services Manager on Windows 7 and try to connect, I get the error: "The rpc server is unavailable" What could cause this? Has there been some fundamental change in Remote Desktop Services Manager, does it connect in a different way somehow? Update #1 Turned off firewall on the Windows XP box and the "The rpc server is unavailable" error went away; so RDSM seems to be using an entirely new port/connection/service compared to mstsc.exe or the old Remote Desktops Admin tool. Now... after disabling the firewall, I get a new error: Access is Denied. After doing some googling, I found some articles discussing this; basically, the error is very misleading - the actual problem is, if either side of the connection has dual monitors, and they are not both Win7 Ultimate, then you cannot connect using Remote Desktop Services Manager...the reason is, by default it uses the /multimon switch, and this switch requires a certain level of Windows license - and, there seems to be no way of changing this default (if anyone knows of a way to change this default, please post an answer or comment!). Nice going Microsoft. http://social.technet.microsoft.com/Forums/en-US/windowsserver2008r2rds/thread/4d06278f-e0f4-4f8e-a8e1-3697ee967ef4 http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Windows/Windows_7/Q_26225743.html

  • Best SSD tweaks for Windows 7

    - by Nick Berardi
    I have seen many articles about tweaking an SSD, but many of them seem outdated, or too broad (read all Windows XP, Vista, and Windows 7 general tweaks). And I know that Windows 7 has been specifically tweaked for SSD by the Windows team, so I don't want to do something that was written for Windows XP in mind and end up circumventing something the Windows team has specifically designed in to Windows 7. So my question is what are the best SSD tweaks for Windows 7 that you have found to get the performance out of your drive? I hope to make a comprehensive list in the answers below so there won't be so much disinformation in the forums about what to do and what not to do. Here are a few that I see posted up on the forums alot, and some questions to get the discussion started: Disabling Superfetch. Yes or No Disabling Page File or limiting it to a really small size such as 500 MB. Disabling Indexing. Yes or No Disabling Defragmenting. Yes or No What are your thoughts do you have any that have worked for you? When providing an answer please do your best to back it up with a reason and possibly some documentation from MSDN, TechNet, or another credible source.

  • Ubuntu 12.04 Very slow especially with Android Studio

    - by Nada
    I have an old laptop with the following specification: Memory: 485 MiB, Processor: Genuine intel CPU T2300 @ 1.66 GHz ×2, OS Type: 32 bit, Disk: 78.1 GB, I installed on it Ubuntu 12.04 LTS and I noticed that the overall system is very slow in responding. I tried to search about that in the internet and I found some articles talking about how to make Ubuntu 12.04 LTS run fast I applied all what they said including download LXDE desktop environment and then nothing different in the system response time. Then I need to develop some android applications so, I download Android Studio (Beta) 0.8.6. The problem became worse than before whenever I tried to open the Android Studio the screen is frozen for some minutes then it took time to download the projects and initialize the work space also, when I tried to move the cursor he is move very slowly. When I tried to run my first application on the AVD it took three hours and still not run yet. I delete the Android Studio and install it again several times, I was trying to solve the problem but still nothing change. Please if you have any suggestions that may help me make my laptop and Android Studio work faster I will appreciate it for you. Thank you in advance.

  • Why is only one wget command working in my crontab?

    - by afEkenholm
    I wish to fetch content from a PHP script on my server two times a day, altering a query variable lang to set what language we want, and save this content in two language specific files. This is my crontab: */15 * * * * ~root/apache.sh > /var/log/checkapache.log 10 0 * * * wget -O /path/to/file-sv.sql "http://mydomain.com/path/?lang=sv" 11 0 * * * wget -O /path/to/file-en.sql "http://mydomain.com/path/?lang=en" The problem is that only the first wget command line is being executed (or to be precise: the only file that is being written is /path/to/file-sv.sql). If I switch the second and the third row, /path/to/file-en.sql gets written instead. The first line always runs as expected, no matter where it is. I then tried using lynx -dump "http://mydomain.com/path/?lang=xx" > /path/to/file-xx.sql to no avail; still only the first lynx line executed successfully. Even mixing wget and lynx did not change this! Getting kinda desperate! Am I missing something? There are thousands of articles on crontab (combined with) wget or lynx, but all seems to cover basic setups and syntax. Does anyone got a clue of what I am doing wrong? Thanks, Alexander

  • Terminal is not letting me make commands unless I hit enter a bunch of times

    - by ninja08
    Whenever I open terminal it normally allows me to immediately begin making commands. Only earlier today I did the setup for github here https://help.github.com/articles/set-up-git And then all of a sudden the thing where I give terminal commands won't allow me to give it commands unless I hit enter a few times. This is what it looks like: Last login: Fri Nov 9 11:43:28 on ttys001 mysql.save: Permission denied mysql.save: Permission denied /Users/Nick/.zshrc:32: command not found:  . ~ git: ? ~ git: ? ~ git: ? See the big space? That's because it simply will never show the ~ git: thing unless I hit enter 3-4 times. Also, it never used to say ~ git: before I did the git setup. I'm not sure what I changed. I've checked the zshrc file and commented everything out to find the line causing the problem. I've done that and it turns out it was the source $ZSH/oh-my-zsh.sh Within the oh-my-zsh.sh file I've commented out each block of code for the file starting at the top and I've found that this block is causing it: # Load the theme if [ "$ZSH_THEME" = "random" ] then themes=($ZSH/themes/*zsh-theme) N=${#themes[@]} ((N=(RANDOM%N)+1)) RANDOM_THEME=${themes[$N]} source "$RANDOM_THEME" echo "[oh-my-zsh] Random theme '$RANDOM_THEME' loaded..." else if [ ! "$ZSH_THEME" = "" ] then if [ -f "$ZSH_CUSTOM/$ZSH_THEME.zsh-theme" ] then source "$ZSH_CUSTOM/$ZSH_THEME.zsh-theme" else source "$ZSH/themes/$ZSH_THEME.zsh-theme" fi fi fi

  • What does SQL Server's BACKUPIO wait type mean?

    - by solublefish
    I'm using Sql Server 2008 ("R1"), with some maintenance plans that back up my databases to a network share. Some of my backup jobs show long waits of type "BACKUPIO". Of course it seems like this is an I/O subsystem limitation, but I'm skeptical. Perfmon stats for I/O on the production (source) server are well within normal trends for that server. The destination server shows a sustained 7MB/s write rate, which seems incredibly low, even for a slow disk. The network link is gigabit ethernet and nowhere near saturated. The few docs I've turned up about BACKUPIO indicate that it's not specifically a wait on I/O, surprisingly enough. This MSFT doc says it's abnormal unless you're using a tape drive, which I'm not. But it doesn't say (or I don't understand) exactly what resource is missing. http://www.docstoc.com/docs/24580659/Performance-Tuning-in-SQL-Server-2005 And this piece says it's not related to I/O performance at all. http://www.informit.com/articles/article.aspx?p=686168&seqNum=5 "Note that BACKUPIO and IO_AUDIT_MUTEX are not related to IO performance." Anyway, does anyone know what BACKUPIO actually means and/or what I can do to diagnose or eliminate it?

  • Powershell Get-Process cannot connect to remote computer

    - by amandion
    I've been struggling with this for a few hours and can't figure this out. I have two Windows 7 computers. One is my workstation that is using Powershell to do administrative maintenance. The other is the machine I'd like to use Powershell remoting on to execute remote Powershell cmdlets on. On both computers, I've enabled Powershell remoting and added all computers to TrustedHosts with the * value. On the remote computer, I've started the Remote registry service and ensured that the DCOM, Winmgmt and the Winrm services are running. Firewall is disabled on remote machine too. The cmdlet I try to run is: Get-Process -ComputerName $name Where $name is the name of the remote machine. I keep getting an error saying that it could not connect to the remote PC. I've also tried using the IP and I get the same error. These PCs are not in a domain. I am able to do the following successfully: Invoke-Command {get-Process} -ComputerName $name -Credential $creds Where $name is the machine name and $creds is the user name and password for the remote computer's local Admin account. This gives me the same output I would expect. While this is an acceptable workaround, I am curious, why doesn't using get-process with remoting work as it should? I've seen a few articles on the web suggesting people have had success with it on its own. Each time I am using Powershell on my workstation with elevated privileges. Any ideas?

  • Low-traffic WordPress website on Apache keeps crashing server

    - by OC2PS
    I have recently moved my low-moderate traffic (1000 UAUs, 5000 pageviews on a busy day) website from shared hosting to a Centos 6 64-bit VPS with Apache and cPanel running on 4 quad-core processor (likely oversold) and 3GB memory (Xen). We've had problems from the beginning. The server keeps crashing. It seems PHP keeps expanding till it consumes all the memory and crashes the server. Some folks have suggested that I should abandon Apache/cPanel/PHP/mySQL and go with nginX/Varnish/PHP-FPM/SQLite. But that's just not possible for me as I am not very tech savvy and need a simple GUI like cPanel to be able to manage the mundane management tasks (can't afford to hire system administrator or get fully managed hosting). I have come across several posts discussing optimization of Apache for WordPress. But all of these lead to articles that are pretty dated such as this ~4 year old one from Jan 2009 - http://thethemefoundry.com/blog/optimize-apache-wordpress/ The article is pretty detailed and seems helpful, but I stumble even on the first step. My httpd.conf only has 2 loadmodule commands LoadModule fastinclude_module modules/mod_fastinclude.so LoadModule bwlimited_module modules/mod_bwlimited.so So I go total bust right there. Further, my httpd.conf says Direct modifications to the Apache configuration file may be lost upon subsequent regeneration of the configuration file. To have modifications retained, all modifications must be checked into the configuration system by running: /usr/local/cpanel/bin/apache_conf_distiller I am having trouble finding where to change the modules in WHM. Please can someone help me with updated guidelines on how to optimize Apache for WordPress? Many thanks! P.S. The WordPress installation also has WP Super Cache installed. P.P.S. I also have phpBB, OpenCart, and Menalto Gallery installed.

  • mod_rewrite changes case even if not matching RewriteCond?

    - by kirdie
    I have a really strange problem with my MediaWiki which I want to have articles of the form mywiki.org/MyArticle. Now I got most of it to work using the following code but it mysteriously cannot display the logo anymore. RewriteEngine On # don't rewrite valid requests to files and directories RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-f RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-d # mywiki.org/MyArticle gets rewritten to mywiki.org/index.php/MyArticle RewriteRule ^/(.*)$ /index.php/$1 [L,QSA] Now when I type in mywiki.org/img/logo.jpg in my browser the adress changes to http://wiki.geoknow.eu/Img/logo.jpg (capital I) and I get to the empty article page but the image is definitely there (in my document root under the img folder): /var/www/mywiki.org$ ls img logo.jpg So far so bad. But now it gets really crazy: When I add RewriteCond %{REQUEST_URI} !^/.*\.jpg my adress still gets rewritten and my access log says - - [05/Dec/2012:16:30:21 +0100] "GET /Img/geoknow_logo.jpg HTTP/1.1" 404 509 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:17.0) Gecko/17.0 Firefox/17.0" Where does that capital I in Img come from? The rule is not even executed because at least one condition is definitely not met now and I also don't have any to lowercase-transformation defined anywhere. What is happening there and how can I repair this? P.S.: Now all of the sudden the problem went away (the image is displayed as it should and there is no capital replacement anymore. What can cause this and why does it spontanously appear and disappear?

  • How to resolve 'No internet connectivity issues' with a Virtualised 2008 R2 Server using Forefront UAG

    - by user684589
    I have spent some considerable time reading up on as many possible blogs and articles as I can to help me solve why my VM (Running on Hyper-V) for DirectAccess has suddenly stopped being able to access the internet. The VM setup shares the same internet connection on which I have written and submitted this question so I know that the actual underlying internet connection is fully functional. Previous to last week the DirectAccess was fully functional and had no issues. This is a recent problem which was led up to by a number of consistent crashes on the DA machine when access was attempted. Upon reboot all seemed well until recently. I am not certain whether it is relevant, but previously to this I had a number of power issues where the entire VM host shutdown unexpectedly leaving around 8 VM's in a bad way. Upon restart, the UAG DirectAccess machine was unable to access its configuration service (although the service was started) but this seemed to relate to the Light-Weight Active Directory Service AD LDS which had a corrupted database. Having repaired this database, I restarted the service and could subsequently reconnect to the configuration service again. For good measure I re-bound the network adapters (virtualised through Hyper-V) and DirectAccess claimed to be all happy again. However as it stands my machine is still unable to access the internet showing the "No internet connectivity" exclamation mark for the external facing NIC. I have also tried removing the adapters, disabling, re-enabling and the problem persists. The intranet part of the VM CorpNet seems to be fully functional as before and I'm running out of ideas. Any input would be greatly appreciated. I am not an advanced Domain Administrator so please be gentle.

  • How to short-circuit Eclipse AutoComplete when "by relevance" Sorting is enabled?

    I know there's a number of autocomplete articles scattered around stack and eclipse relevant communities. I haven't seen a solution that I have been able to make work. Essentially it goes like this... I like sorting by relevance (since it usually has a decent priority), but sometimes I want to short circuit the autocomplete without having to hit x 2. If I have a class that has a couple methods like, getThis(), getThat, and get(), and eclipse picks up that I usually use getThis(), but every once in a while I want the get() method. So I type "Class" "period" "get(" -- whoops eclipse just filled in getThis(). When the sorting is alphabetically, this isn't an issue, but "by relevance" is a nice default. Just wondering if I'm missing the boat on something. Obviously one solution is to increase the latency on the autocomplete popup, but get() might just be an example. There might a situation where the method I want is a few parameters and maybe more than 3 keystrokes. Thank you.

  • Tuning Linux + HAProxy

    - by react
    I'm currently rolling out HAProxy on Centos 6 which will send requests to some Apache HTTPD servers and I'm having issues with performance. I've spent the last couple of days googling and still can't seem to get past 10k/sec connections consistently when benchmarking (sometimes I do get 30k/sec though). I've pinned the IRQ's of the TX/RX queues for both the internal and external NICS to separate CPU cores and made sure HAProxy is pinned to it's own core. I've also made the following adjustments to sysctl.conf: # Max open file descriptors fs.file-max = 331287 # TCP Tuning net.ipv4.tcp_tw_reuse = 1 net.ipv4.ip_local_port_range = 1024 65023 net.ipv4.tcp_max_syn_backlog = 10240 net.ipv4.tcp_max_tw_buckets = 400000 net.ipv4.tcp_max_orphans = 60000 net.ipv4.tcp_synack_retries = 3 net.core.somaxconn = 40000 net.ipv4.tcp_rmem = 4096 8192 16384 net.ipv4.tcp_wmem = 4096 8192 16384 net.ipv4.tcp_mem = 65536 98304 131072 net.core.netdev_max_backlog = 40000 net.ipv4.tcp_tw_reuse = 1 If I use AB to hit the a webserver directly I easily get 30k/s connections. If I stop the webservers and use AB to hit HAProxy then I get 30k/s connections but obviously it's useless. I've also disabled iptables for now since I read that nf_conntrack can slow everything down, no change. I've also disabled the irqbalance service. The fact that I can hit each individual device with 30k/s makes me believe the tuning of the servers is OK and that it must be some HAProxy config? Here's the config which I've built from reading tuning articles, etc http://pastebin.com/zsCyAtgU The server is a dual Xeon CPU E5-2620 (6 cores) with 32GB of RAM. Running Centos 6.2 x64. The private and public interfaces are on separate NICS. Anyone have any ideas? Thanks.

  • What is the correct approach i should use for an application that requires amazon S3 uploads and SimpleDB data management?

    - by Luis Oscar
    I am developing an application for iOS and that is going smoothly, the problem is that I am very new at server sided things. I am totally confused about how to correctly use Amazon Web Services for this purpose. What I want to do is very simple. I want my application to be able to query a servlet hosted in EC2 to be able to retrieve pictures and data based on some criteria from S3 and SImpleDB respectively. Also the application should be able to upload pictures into a S3 bucket and register the information in the SImpleDB. My main concerns are security and costs, So far i was using Amazon Token Vending Machine but I haven't been successful when trying to customize it, and while researching I discovered that on the long run it is very expensive. The ultimate goal is to handle a "social" picture service for my iOS application. Being able to register new users, authenticate these users. See what permissions they have to which pictures from the bucked. And all this without having to worry about Third party people from accessing the private pictures of my users. Sorry for this question but I am really clueless about how to handle this... I have tried reading many articles but all these server stuff looks very scary.

  • VPN with VLANs? [closed]

    - by Craig
    As usual, I'm sure I'm in way over my head on this one. My networking skills are limited; so, bear with me if you will. What I have are a few testing servers at my house as well as at a friends house that I want to link together so they can see each other (VPN right? I've done those before). We want to be able to see all the servers and work with them from either location. All the servers also need to be able to see each other. But, we don't want to see each others PCs, printers, PS3s etc. How do we pull that trick off? Multiple VLAN?... subnets?... what? If hardware matters, I have an old PC I was planning on loading pfSense onto because my current el-cheapo router doesn't support VPN. The VPN linking the houses is about the only thing I'm sure on. Beyond that, I'm lost. I'm not a complete noob; but, like I said, I'm not so sharp with the more complex networking. I do however read well... So use lots of descriptive words and feel free to link away to long dry articles if necessary. :-)
