  • Active Directory + IIS + SQL + ASP.NET

    - by Amira Elsayed Ismail
    I have sent the following question to stackoverflow website I have installed Windows server 2008 r2 on a virtual machine, Can I install Active directory with domain controller + IIS + SQL server on the same machine? I want to make web application and this web application will authenticate users from Active Directory, the web application should be published on the server IIS and the users should access it remotely from their home using domain name of my machine, Someone tell me that its very wrong to have IIS and Active directory on the same machine I got the following Answer You can't use ActiveDirectory over the internet. At least not without something like a VPN as a middle man. Their home computers will not be joined to the domain, so there is no pass-through authentication. Yes, it's a bad idea to put AD on the web server. Why is too complex to get into in an answer here. Suffice it to say that even if you did do this, it's probably would not work the way you are thinking it should. It's not impossible to do this. For instance, many of the Microsoft "Small Businesss" products put IIS, AD, and SQL Server on the same server. But, you kind of have to know what you're doing to configure it securely. Then I add the following comment Thanks for ur reply.so what you think about the best way to do this as I didn't do anything like that before should I install active directory on a machine and IIS on another machine ? and what about SQL should I add it to the same server of active directory ? I didn't mentioned also that it will be Microsoft dynamics server that will access some information about work and i have to read data from axapta also ? also what is VPN and how can I use it to let users access my web application anywhere ? Sorry for my long questions and thanks in advance so please if anyone can help I will be thankful

  • How can I tell my dd-wrt router to use someone's Amazon Affiliates link when I point my browser to amazon.com?

    - by Michael Paul
    Here's what I'd like to do. Instead of a one-time donation to one of my favorite free tools (junecloud.com) I'd like to do what they suggest here and use their Amazon Affiliates link to do all my Amazon shopping. I shop at amazon once or twice a week, so this is a great way to let them earn lots of long-term cash without me dropping a dime. My thought was to go into my dd-wrt enabled router and tell it, "any time I go to amazon.com on any computer in the house, please go to http://www.amazon.com/gp/redirect.html?link_code=ur2&tag=junecloud-20&camp=1789&creative=9325&location=%2F instead. (That URL simply redirects me to amazon.com but every purchase I make during that session is credited to JuneCloud.) Once logged into dd-wrt, I went to Services Services DNSMasq but I'm not really sure how to get it to work from there, or if it's even possible. I know I can redirect IP addresses, but I'm looking to redirect someone on my network from amazon.com to the special amazon affiliate code link. Hope that's clear. Thanks for any replies!

  • Malware Defense Shows Up in PlayOn Settings/Logs Although System Has Been Thoroughly Cleaned

    - by nicorellius
    I was hit really hard by some nasty malware: Malware Defense. I was doing something I should not have been doing when I got it (surfing Pirate Bay for TV shows). It locked up my system and I had to reboot in safe mode. I was able to shut down the process and remove it using a malware killer tool. I then installed, after my machine was cleaned up a bit, Clamwin, Malwarebytes, and another AV tool. I cleaned the heck out of my system. Simultaneously, while this was going on, I was having trouble with my media-server, PlayOn. This tool is great, but has some bugs. One in particular is that it will not function well with AV software running. I found a way to allow the new AV software to run while using PlayOn, but it still says I have Malware Defense on. Firstly, Malware Defense is long gone. I cleaned all remnants from my registry and scoured my system with the above tools multiple times. PlayOn is getting some information that I have this crap installed on my system, but it's not. The system runs OK, but not optimally. I have a feeling it is causing my streaming to be interrupted sometimes. How is it that I can't even find Malware Defense on my system if I tried but yet somehow PlayOn is getting a finger print of it somewhere? I have gone back and forth with MediaMall to no avail. I kind of just gave up, because the streaming works OK. BTW, I also uninstalled/reinstalled PlayOn several times, reverted back to previous versions, etc. The only thing I haven't done is reformat my disk and reinstall Windows. I really don't want to do this if there is another way to remove this little print. Any ideas?

  • Possible DNS Injection and/or SSL hijack?

    - by Anthony
    So if I go to my site without indicating the protocol, I'm taken to: http://example.org/test.php But if I go directly to: https://example.org/test.php I get a 404 back. If I go to just: https://example.org I get a totally different site (a page about martial arts). I went to the site via https not very long ago (maybe a week?) and it was fine. This is a shared server, as I understand it, and I do not have shell access, so I'm limited to the site's CPanel to do any further investigations. But when I go to: example.org:2083 I'm taken to https://example.org:2083, which, if someone has taken over the SSL port, could mean they have taken over the 2083 part as well (at least in my paranoid mind). I'm made more nervous by the fact that the cpanel login page at the above address looks very new (better, really) compared to the last time I went to it over the weekend. It's possible that wires got crossed somewhere after a system update, but I don't want to put in my name username and password in case it's a phishing attempt. Is there any way to know for sure without shell access to know for sure if someone has taken over? If I look up the IP address for the host name, the IP address matches what I have on a phpinfo page I can get to over http. If I go to the IP address directly on port 2083, I get the same login mentioned above (new and and suspiciously nice). But the SSL cert shows as good when I go this route. So if that's the case (I know the IP is right, the cert checks out, and there isn't any DNS involved), is that enough to feel safe at that point of entry? Finally, if I can safely log in via the IP, does anyone have any advice on where to check first on CPanel for why the SSL port is forwarding to a site on karate? Thanks.

  • Burn .srt subtitles to AVC encoded video (transcoding with hardsubs) [closed]

    - by Saxtus
    Possible Duplicate: How do I hard code a movie with subtitles? I am looking for a software (or combination of software) that will allow me to hard burn subtitles from an .srt file, that has italics and bold typefaces, to an H.264/AVC encoded video so it can played from a desktop player that can't display external subtitles correctly. Ideally it could use Directshow as input as DirectVobSub makes nice job showing the subtitles as they should (allowing me to globally adjust font and size). CUDA use, to speed up encoding, will be great but not necessary. Video source is also H.264/AVC encoded. Audio is AC-3 5.1 and should be retained too but I have no problem re-muxin it later as long as it keeps synced. Until now I've unsuccessfully tested: Avisynth 2.58 Unable to make Direcvobsub to launch through it TextSub() command renders subtitles with fixed font/size and doesn't decode tags Malformed audio TMPGEnc 4.0 XPress 4.7.4.299 Audio downmixed to 2.0 Importing of subtitles doesn't decode tags Badaboom 1.2.1.7 No importing of subtitles at all SUPER © 2010.build.37 "Directshow decode" has similar effect as Avisynth above Other modes doesn't appear to allow any subtitles in Thank you.

  • XP SP2 Event log not logging events

    - by Weedfreer
    I have a problem whereby a terminal appears not to be logging events correctly and occasionally appears to have problems communicating accross the network.The terminal has previously been infected with a virus which apears to have 'played' with the default group policy in the standard user profile. Although, outwardly, the terminal appears to be working normally I still have a nagging feeling that it isn't quite back to the way it was. It was infected by a user plugging in a USB Stick while the company was using the older version of the AV software...typically a week or so before it was updated.I have configured the Event logs to Overwrite as required and to be 5056KB in Maximum size. I have also attempted:- Disabling the Event Log service & restarting Renewing the EVT files in Windows\system32\config directory Restarting the event log service and restarting Clearing the event log in the Services MMC Resetting the Filters to Default in the services MMC Using the EVENTCREATE command remotely from a CMD window on the server to force an event creation event. So far the only operation to have any sort of success is the remote computer EVENTCREATE command from a CMD window on the server. As it stands, the only other time that the computer has managed to create events is while it is being restarted.Has anyone gotany ideas on how to proceed? I'm thinking that possibly a refresh of the 'Windows\system32\config\SystemProfile' folder. I'm also thinking about running a tool such as Malwarebytes but this could be slightly controvertial as the system needs to be running on 'up-time' for as long as possible. I'm also wonderign whether anyone knows of any Windows admin tools that allow me to control the event logging options or default security options so that i could get it back to some sort of standard.What I'm trying to avoid is a complte re-imaging of the terminal. Although this is an option, I dont really want to have to take it if i dont need to.Many thanks in advance for any suggestions anyone may be able to provide.

  • Is there a way in Windows 7 to disable "journaling"?

    - by Psycogeek
    C:\$extend\$Usn.Jrnl:$J:$data Here is a picture finally. The large strip in the center of the top band is the largest chunk, in the other, grey areas are the various clusters with it. On the right, the big long grey line is $logfile (not paging), and it is 63&nbsb;MB. Paging, 500&nbsb;MB is the dark cyan chunk, next to the yellow MFTres in the inner rings.. The disk was defragged so they could be seen easier. Not all clusters of this type of file are tagged, but the idea is there. The disk is 4k clusters, now about 12 GB size. Each cute little block in the picture is .81 MB and represents 207 clusters. The dkGreen section, is mostly the whole Winsxs pile, also interesting when they keep telling us it doesn't take much disk space. Wikipedia suggests that in previous NT systems "USN journaling" would be turned on when enabled (assumes it could also be turned off?). What aspects, services, or program is working on putting that stuff all over the disk which is known by $jrnl$ type clusters, even if it is not actual USN journaling? Is it possible in a Windows 7 system to completly disable the journaling, and what would be the ramifications of that? On a Windows XP NTFS system, I do not recall seeing the quantity of disk clusters used with these $jrnl$ names, so I do not recall this being necessary in this quantity for an NTFS file system itself? I understand that it would not be there, if it did not have a useful function :-) Information about how wonderful is fine, if that information will help track down what parts of the system create and use it. Change Journals states: Change journals are also needed to recover file system indexing Hmm, that might explain some of them, or why it was left on the disk. A crash while background indexing?

  • Looking for a recommendation on measuring a high availability app that is using a CDN.

    - by T Reddy
    I work for a Fortune 500 company that struggles with accurately measuring performance and availability for high availability applications (i.e., apps that are up 99.5% with 5 seconds page to page navigation). We factor in both scheduled and unscheduled downtime to determine this availability number. However, we recently added a CDN into the mix, which kind of complicates our metrics a bit. The CDN now handles about 75% of our traffic, while sending the remainder to our own servers. We attempt to measure what we call a "true user experience" (i.e., our testing scripts emulate a typical user clicking through the application.) These monitoring scripts sit outside of our network, which means we're hitting the CDN about 75% of the time. Management has decided that we take the worst case scenario to measure availability. So if our origin servers are having problems, but yet the CDN is serving content just fine, we still take a hit on availability. The same is true the other way around. My thought is that as long as the "user experience" is successful, we should not unnecessarily punish ourselves. After all, a CDN is there to improve performance and availability! I'm just wondering if anyone has any knowledge of how other Fortune 500 companies calculate their availability numbers? I look at apple.com, for instance, of a storefront that uses a CDN that never seems to be down (unless there is about to be a major product announcement.) It would be great to have some hard, factual data because I don't believe that we need to unnecessarily hurt ourselves on these metrics. We are making business decisions based on these numbers. I can say, however, given that these metrics are visible to management, issues get addressed and resolved pretty fast (read: we cut through the red-tape pretty quick.) Unfortunately, as a developer, I don't want management to think that the application is up or down because some external factor (i.e., CDN) is influencing the numbers. Thoughts? (I mistakenly posted this question on StackOverflow, sorry in advance for the cross-post)

  • RDP Connection to Windows 7 stays really slow

    - by Pavlo
    I have an Issue with connecting to Windows 7 via RDP. I can open an RDP Session, but regardless of any settings, the responce times are really long. This in particulary is the case when opening a web page in a browser. I've tried IE, Firefox and Google Chrome. I also use RDP connection to a Windows 2008 Server from the same client machine, and the speed is very normal with all features turned on. We have Gigabit Ethernet here. So I think it can not be the client's fault. What concerns Windows 7 Machine, I've tried shutting all the sraphic features off and turning the color levels to 256 colors. Result - the same. If I work locally on the machine - I can not see any lags. What else have I tried: Using old RDP 5 Client from Microsoft Setting network autotuninglevel as seen here Do You have some ideas? Thanks in advance! Update the problem seems to be with rendering window contents. All the window borders and pannes are rendered pretty quickly, but the content shows up very slowly. Also mouse movements are recognised by the Win 7 box only after some period. Are there some hidden settings in the RDP, where one could turn some advanced features off or turn some caching on? I use Bitmap Caching, but this apparently doesn't help.

  • Problems with Windows 7 restore

    - by Chris Lively
    My WD raptor 150 failed with a nice clicking noise. So, I picked up a velociraptor 300 and popped it in. I had windows set to do a full system backup nightly, so I figured the recovery ought to go easily. Well, it isn't. It is currently stuck on a screen that says: "Windows is restoring your computer from the system image. This might take from a few minutes to a few hours" Below that is a rather large progress meter with maybe the first block filled in. Below that is a message that says "Restoring disk (C:)..." It's been that way for over an hour. The first time around, I gave up after 2 hours. I then booted into the system recovery options and went to a command prompt and ran a chkdsk on the new drive. It showed several file inconsistencies and not much else. I ran a chkdsk /f on it and tried again... Which is where I'm at now. I can't see that the restore process should take this long before. Any ideas? UPDATE After 10 hours, it's still on "Restoring disk (C:)" and the progress meter is at roughly 5%. I'm guessing at the 5% as there isn't an actual number or anything else that I can look at showing what it's actually doing. The backup contains roughly 120GB of data. How slow is windows restore?

  • Outlook won't re-connect to exchange after network is re-connected

    - by stan503
    I have a setup at my desk where I connect my computer to a an RJ45 switch that switches between two networks. One network is the corporate network, which is maintained by my company's IT, and the other is my own private network where I do testing (the two networks have to be separated). The corporate network hosts the exchange server where I get e-mail. When I switch from the private network to the corporate network, I expect Outlook to re-connect to the exchange server. However, I have found that sometimes when I come back, Outlook take an extremely long time to re-connect. Send/Receive will give me back the error 'The server is not available' (0x8004011D). It will sit there for 10 minutes to a few hours before it finally re-connects. The only other option is to reboot my computer, which is a huge pain for me since I run multiple VMs on it. This usually happens when I'm connected to the private network for a significant amount of time, so I'm thinking it's because Outlook has cached the network status. Is there a way to force Outlook to do a 'hard' re-connect to the exchange server? I'm using Windows XP SP 3 with Outlook 2007.

  • Software way to cool down an old MacBook Pro

    - by notMacBookProSuperUser
    Hi all, First a little background: I've got lots of computers, including Linux PCs and two MacBook Pro (and a MacMini). My concern is with my 'old' MacBookPro (Core Duo). It really does overheat. Warranty is long void. Years ago (I'd say 2.5 years ago or so) one day it overheated so bad that the battery inflated due to the heat. I got a new battery for free but it's still getting incredibly hot (much other than any other computer I've got: my newer Core 2 Duo MacBook Pro doesn't get nearly as hot as the old one. It s really a pain because I use my old MBP when I m in front of TV, having it on my lap, and it can really become unbearable. I don't want to open that old MBP. On Linux I can force a new CPU 'governor' that decides how the CPU is allowed to operate: it can be 'on demand', 'always max speed', 'always speed x', etc. Does the same exist under MacOS X? Is there a way, say if a 1.86 Ghz Core Duo can run at 1.6 Ghz, to ask MacOS X: "never run this CPU above 1.6 Ghz" ?

  • pppd disconnects from 3G, doesn't reconnect, w/ persist set

    - by bytenik
    I am trying to configure pppd to connect to a 3G network (Sprint, in this case) and then stay connected, reconnecting automatically if the remote connection is terminated. I have enabled the persist option. My configuration file is as follows: hide-password noauth connect "/usr/sbin/chat -v -f /etc/chatscripts/cellular" debug /dev/cell 921600 defaultroute noipdefault user " " persist maxfail 0 lcp-echo-failure 10 lcp-echo-interval 60 holdoff 5 However, when the peer disconnects the connection, pppd often waits a long time (substantially more than my holdoff) to reconnect the modem -- if it ever reconnects at all! An example log showing this: May 23 05:17:24 00270e0a8888 pppd[2408]: rcvd [LCP TermReq id=0x26] May 23 05:17:24 00270e0a8888 pppd[2408]: LCP terminated by peer May 23 05:17:24 00270e0a8888 pppd[2408]: Connect time 60.1 minutes.

I had a friend monitoring the server so I'm not certain that this wasn't a manual reconnection. Either way, it either took almost an hour to reconnect or never reconnected. Shouldn't persist + holdoff 5 cause this to automatically reconnect after 5 seconds of the link terminating?

  • Cannot establish XMPP server-to-server connection with gmail

    - by v_2e
    My jabber-server fails to connect to gmail.com giving the error: outgoing s2s stream myserver.com.ua-bot.talk.google.com closed: undefined-condition (myserver.com.ua is a Google Apps Domain with Talk service enabled.) I am using the Prosody XMPP server. It works just fine with other jabber-servers I tested so far (e.g. jabber.ru). However, when some of my clients tries to add a gmail contact to his contact-list, the subscription request lasts forever, and the Prosody gives the following sequence of messages in its log: Oct 21 22:57:16 s2sout95897f8 info Beginning new connection attempt to gmail.com ([173.194.70.125]:5269) Oct 21 22:57:16 s2sout95897f8 info sent dialback key on outgoing s2s stream Oct 21 22:57:16 s2sout95897f8 info Session closed by remote with error: undefined-condition (myserver.com.ua is a Google Apps Domain with Talk service enabled.)

As for the Google services, I did have a google account where I added the domain name under question to the Webmasters tools page. However, I deleted my account long ago, so now it is unclear, how any of the Google services can relate to my domain name. So my question is: What is the real cause of this problem (my jabber-server configuration or imaginary Google account or something else) and how can I make my Prosody server connect to gmail.com jabber service?

  • Apache crashes every 5min

    - by Simon
    I'm relatively new to server issues, having a site of mine that I started early in the year grow beyond my capabilities of managing it. I need help. I recently moved out of my shared hosting environment onto a dedicated virtual server from Mediatemple. Each week, I run a script that fetches data from my DB, fetches data from last.fm's API and then tweets information to Twitter. My server uses Virtuozzo and when the script runs, Apache crashes every 5min. I checked and saw that the 'kmemsize' parameter reaches its cap (its 13mb). I realise my problem. The MySQL process stays open for long while Apache needs to handle lots of incoming links (about 200 000 pageviews for that day according to my previous host's AWSTATS). Yes, I'm quite unexperienced in this, and I'm clearly killing the server with too many incoming links while it has to manage the updating of the DB. So that is the precedent: I want a few answers. 1) Why did my shared hosting environment not crash apache every 5min? It ran fine, the site only slowed a lot. Clearly, it must be the virtual container and the kmemsize limit? 2) Where do I go from here? Would a physical server (not a virtual container) encounter the same problems? I sent a support request to Mediatemple as well. I need all the help I can get.

  • Remote Socket Read In Multi-Threaded Application Returns Zero Bytes or EINTR (104)

    - by user39891
    Hi. Am a c-coder for a while now - neither a newbie nor an expert. Now, I have a certain daemoned application in C on a PPC Linux. I use PHP's socket_connect as a client to connect to this service locally. The server uses epoll for multiplexing connections via a Unix socket. A user submitted string is parsed for certain characters/words using strstr() and if found, spawns 4 joinable threads to different websites simultaneously. I use socket, connect, write and read, to interact with the said webservers via TCP on their port 80 in each thread. All connections and writes seems successful. Reads to the webserver sockets fail however, with either (A) all 3 threads seem to hang, and only one thread returns -1 and errno is set to 104. The responding thread takes like 10 minutes - an eternity long:-(. *I read somewhere that the 104 (is EINTR?), which in the network context suggests that ...'the connection was reset by peer'; or (B) 0 bytes from 3 threads, and only 1 of the 4 threads actually returns some data. Isn't the socket read/write thread-safe? I use thread-safe (and reentrant) libc functions such as strtok_r, gethostbyname_r, etc. *I doubt that the said webhosts are actually resetting the connection, because when I run a single-threaded standalone (everything else equal) all things works perfectly right, but of course in series not parallel. There's a second problem too (oops), I can't write back to the client who connect to my epoll-ed Unix socket. My daemon application will hang and hog CPU 100% for ever. Yet nothing is written to the clients end. Am sure the client (a very typical PHP socket application) hasn't closed the connection whenever this is happening - no error(s) detected either. Any ideas? I cannot figure-out whatever is wrong even with Valgrind, GDB or much logging. Kindly help where you can.

  • How to Re-install an App that Shows up in the Appstore as 'Update' Instead of 'Buy App'

    - by Craig Reville
    So long story short: I dropped the wrong app into 'clean my mac' and I hit 'cancel' but it was too late by that point. I rebooted and appstore said it had an update, when I opened appstore it was showing an update for the app I just uninstalled. I tried clicking 'update' but it gives me an error saying it's unable to install after 'downloading'. When I try to go into 'purchased apps' it shows the app as uninstalled so I click 'install' and I get an error saying it's already installed. I'm running Lion OS X, latest version, updated, mac book pro is only a few months old. I tried searching through the entire system to remove all traces of the app, after rebooting appstore no longer shows the app and no longer shows the update but on the apps page it still says 'Update'. I tried reinstalling the app from desktop OUT of the appstore and again says the app is 'already installed'. So after reading more about lion I found an article that spoke about 'BundleID' being the thing that tells appstore what's installed and needing updating however I can't find the location of where the BundleID would be. Any thoughts? I've tried CCleaner, AppCleaner etc and none of them show the app, mainly because it is uninstalled. Update I've spoken to Apple Support who confirmed that there is a file in the system that connects separately to tell the system if there are updates available however they declined to inform me of any further details. Apple also referred me from technical support to iTunes App Store opposed to Mac App Store support and from there I have been referred to AppleCare who are currently 'investigating' this issue. Hopefully there will be a fix that's simple to implement for people having similar issues, this appears to be a more common issue than I previously thought.

  • Drobo-like linux file server - how do I do it?

    - by John Hunt
    I've been pondering for a long time about how I can set up a server which operates much like the Drobo storage thing. The reasons I don't actually want a drobo is because I've heard scare stories, plus I'd like to do this on the cheap. So ideally I'm looking for something like lvm so I can create a logical volume that spans many hard disks of varying sizes... obviously that only offers redundancy if I put the LV on a raid array (as far as I know..) I have however been reading about technologies such as Microsoft's drive extender which duplicates files at the filesystem level and makes sure that the mirrored files are on a different phyiscal disk.. does anyone know or recommend a filesystem or method like this as it'll hopefully make much better use of the space available than raid ever could. Performance isn't an issue, I'd just really like to make the most of the hard disks I have lying around whilst having a bit of redundancy incase a disk dies. I understand full well that this is no replacement for a backup, but I'll only be storing files of medium importance and using the nas itself as a backup of my main pc and other systems. Thanks in advance! I'm hoping zfs or btrfs or something can do something clever for me :)

  • What laptop would be recommended for video-editing or transcoding to blu-ray?

    - by Rob
    I'm looking for a machine (has to be a laptop) reasonably fast enough to handle editing/transcoding/rendering to Blu-ray disc of full true HD 1080p (1920x1080) video from a Samsung R10 camcorder - MPEG4 25fps (not the Sony-Panasonic AVCHD format): To be able to browse through the footage (say, quarter screen is fine for monitoring) and do simple edits - cut out bad bits, add titles, fades, nothing too fancy To be able to burn the footage in 1920x1080p 24p (twenty-four) fps to blu-ray, probably don't mind if I have to leave it for a few hours, or even overnight, as long as its not still running in the morning or takes days. I ALREADY have an external USB 2.0 LG BE06LU10 blu-ray burner. Does quad core make much difference? Or would Dual-core suffice for the above? NVidia because of CUDA for increased speed. What software today can take advantage of this? Which graphics card do I need? So far I've found Dell/Alienware to be well-specified, having a 5yr old Dell laptop that still runs well, albeit slow by today's standards, gives me a good impression. My concerns are too much fan-noise and budget and some Dell Precision Laptops exceed 1500 pounds. Thoughts?

  • Website has become slower on a VPS, was much fast on a shared host. What's wrong?

    - by Arpit Tambi
    My shared host suspended my website stating system overload, so I moved my website to a VPS which has 4GB RAM. But for some reason the website has become very slow. This is the vmstat output - procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu------ r b swpd free buff cache si so bi bo in cs us sy id wa st 1 0 0 3050500 0 0 0 0 0 1 0 0 0 0 100 0 0 Here's the Apache Benchmark output for a STATIC html page I ran on the server itself - Benchmarking www.ask-oracle.com (be patient)...apr_poll: The timeout specified has expired (70007) Total of 20 requests completed Update: Server Config: List item Centos 5.6 4 cores cpu 4 GB RAM LAMP stack with APC Wordpress Only one website It takes almost double time to load now, same website was much fast on shared hosting. I know I need to tweak some settings but have no clue where to start from? I have already tried to optimize apache, mysql etc. Update 2: CPU usage is low, see uptime output: 11:09:02 up 7 days, 21:26, 1 user, load average: 0.09, 0.11, 0.09 Update 3: When I load any webpage, browser shows "Waiting" for a long time and then page loads quickly.

  • What is the best way to recover from a mysql replication fail?

    - by Itai Ganot
    Today, the replication between our master mysql db server and the two replication servers dropped. I have a procedure here which was written a long time ago and i'm not sure it's the fastest method to recover for this issue. I'd like to share with you the procedure and I'd appreciate if you could give your thoughts about it and maybe even tell me how it can be done quicker. At the master: RESET MASTER; FLUSH TABLES WITH READ LOCK; SHOW MASTER STATUS; And copy the values of the result of the last command somewhere. Wihtout closing the connection to the client (because it would release the read lock) issue the command to get a dump of the master: mysqldump mysq Now you can release the lock, even if the dump hasn't end. To do it perform the following command in the mysql client: UNLOCK TABLES; Now copy the dump file to the slave using scp or your preferred tool. At the slave: Open a connection to mysql and type: STOP SLAVE; Load master's data dump with this console command: mysql -uroot -p < mysqldump.sql Sync slave and master logs: RESET SLAVE; CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000001', MASTER_LOG_POS=98; Where the values of the above fields are the ones you copied before. Finally type START SLAVE; And to check that everything is working again, if you type SHOW SLAVE STATUS; you should see: Slave_IO_Running: Yes Slave_SQL_Running: Yes That's it! At the moment i'm in the stage of copying the db from the master to the other two replication servers and it takes more than 6 hours to that point, isn't it too slow? The servers are connected through a 1gb switch.

  • Tips and Suggestions IP Address Re-Addressing?

    - by RSXAdmin
    Hello serverfault Universe, My ever evolving and expanding local area network is currently using a class-C address. My network consists of multiple subnets depending on site/location. 192.168.1.x is site HQ 192.168.5.x is secondary site 192.168.10.x is so on and so forth. Long story short - I have inherited this network design from the previous admin who has left the company which started off with a dozen people and now has just over 300 full time/part time employees. We do not yet have client VPN access; but we do have site to site VPN setup. My question is, in preparation for outside client access to my network via Cisco ASA, I would like to re-address the HQ site because I understand a 192.168.1.x or 192.168.0.x are not very good choices for a company subnet - it may conflict with a home user's LAN when connecting to my LAN, I believe? Through your experience, does anyone out there have any suggestions and tips on how I can proceed with re-addressing my subnets. If I designed this network I would have gone with a 10.0.0.0 (mask 255.255.255.0) so I am leaning towards changing it to fit. Thank you.

  • Guest can't access host windows network share

    - by Asteroza
    HI folks, I've recently run into a strange problem after upgrading to VMware player 3. Certain virtual machines (currently an XP and a VIsta VM) seem to have lost the ability to access the host (XP) network shared folders (SMB). Both VM machines are bridged networking, firewall is up. Host firewall is up. Host and guests use DHCP. All OS are workgroup connected. The Vista VM I am not completely sure, but the XP VM did have access to the host's network shared folders after the player upgrade. Then today it wouldn't work, network path can't be found. Now here's the wierd part. The host's network shared folders can be accessed properly by other PC's on the network (and as far as I know, no settings have been changed). The host is pingable from the guests, and name resolution works. The guests can access network shares on other PC's in the network, and access the internet. My Network Places shows the host PC, but double clicking on it takes a long time before it finally times out with an error. Doing a wireshark packet capture, the guest is sending out the protocol negotiation, and the host is sending a response, but after that the guest behaves like it didn't receive anything and is doing TCP retransmissions. Anybody have any idea what could be wrong? Yes I know I can drag and drop files or setup the special VMware shared folders, but I want to access the host just like any other network accessible shared folder. It just seems really odd when any other computer works, just not between the guest and host.

  • Splitting build cross the network?

    - by Dandikas
    Is there a known solution for splitting build process cross the network machines? Use case: We are an average software development company. We own around 50 development workstations (Quad Core 2.66Ghz, 4 GB ram, 200 GB raid). No need to tell that at any single moment not every machine is loaded to the max. There are 5 to 15 projects running simultaneously at any single moment. Obviously all of them are continuously build on server, than deployed to proper environment. Single project build is taking from 3 to 15 minutes. The problem: Whenever we build 5 projects in a row the last project is going to be ready after around 25 - 50 minutes. Building in parallel does not solve the problem (build is only a part of the game, than you need to deploy, run tests etc.) YES the correct solution is to add another build server, but "That involves buying new Expensive hardware, and we already spent a lot!". Yea, right(damn them)! Anyway. What about splitting build among developers workstation? Lets say whenever we need to build project "A" we check 5 workstations and start build on all that are not overloaded. The build can be canceled by a developer if he really needs all the power of his machine as long as there is at least 1 machine that is still building. After build is finished deployment can be performed to a proper environment (hosted on some server, not on workstation :) ). The bigger the company the more this makes sense to me. Anyone tried something like this? Are there any good practices? Any helpful software?
