• Apache2: Limit simultaneous requests & throttle bandwidth per IP/client?

  - by xentek

  I want to limit simultaneous requests & throttle bandwidth per IP/Client on a single apache vhost. In other words, I want to ensure that this site, which hosts large media files, doesn't get hammered by someone trying to download everything all at once (just happened the other night). I'd like to limit the outgoing transfer speed overall for this site, as well as limit the number of connections a single IP can make to the server to a sane default (i.e. within normal browser limits for multiple requests so page loads aren't effected too much). Bonus points if I can actually scope it to file types (i.e. leave web files alone, but apply these rules to just the media files). We're running Ubuntu 9.04 on all the servers, and have two apache/php servers being load balanced via Round Robin by a squid proxy server. MySQL is running on its own box as well. We've got plenty of bandwidth to give them, so I don't really want overall caps, but just want to throttle the amount of memory/CPU it takes to serve this site. There other sites on these servers that we don't want to apply these rules too, just want to keep this one from hogging all the resources. Let me know if you need more info! Thanks in advance for your suggestions!

• Graphite not running

  - by River

  I'm currently trying to install graphite 0.9.9 on a gentoo box using these instructions from the graphite wiki. Essentially, it fronts graphite using apache and mod_wsgi. Everything seems to have gone well, except that apache / the graphite webapp never seem to return a response to the web browser (the browser continuously waits to load the page). I've turned on the graphite debug info, but the only message in the log files is this, repeated over and over again in info.log (with the pid always changing): Thu Feb 23 01:59:38 2012 :: graphite.wsgi - pid 4810 - reloading search index These instructions have worked for me before to set up graphite on an Ubuntu machine. I suspect that mod_wsgi is dying, but I have confirmed that mod_wsgi works fine when not serving the graphite webapp. This is what my graphite.conf vhost file looks like: WSGISocketPrefix /etc/httpd/wsgi/ <VirtualHost *:80> ServerName # Server name DocumentRoot "/opt/graphite/webapp" ErrorLog /opt/graphite/storage/log/webapp/error.log CustomLog /opt/graphite/storage/log/webapp/access.log common # I've found that an equal number of processes & threads tends # to show the best performance for Graphite (ymmv).

• Sharepoint Central Administration stuck / high CPU usage

  - by johnnyb10

  I'm using WSS 3 and I recently added a new web application to my SharePoint Server. After adding it, I wasn't able to open the Central Administration site. I also noticed that there was a w3wp.exe error (Event ID 1000) in the Event Viewer. The situation now is that the w3wp.exe process is hovering around 50% CPU usage continuously. I installed a program called IIS Peek, and it shows continuous GET requests on the Central Administration site; this happens even if I stop the Central Administration site in IIS. The IP addresses identified in the GET request is my workstation, which is what I used to attempt to access Central Administration after I created the new web application. Can someone explain what's going on and how I might fix it? It seems as if my computer tried to access Central Administration and then it hung, but the page requests that were happening at the time are somehow continuing over and over again. So my two problems are the inability to access Central Administration, and the CPU Usage of w3wp.exe, which I'm assuming are two symptoms of the same problem. I'd like to know if there's anything I can do besides restarting IIS, because we have clients accessing other sites on this server. Thanks.

• Induce Mac graphical login from SSH

  - by Ben Alpert

  The title says it all. Is there a way to make the loginwindow process start a user session by running a command when remotely logged in via SSH as an admin on Mac OS X? When the machine is at the login window (no user is currently logged in), I want it to open up a user's session as if I had clicked on the username and entered a password. Solutions that don't involve scripting the GUI are highly preferred, but this Apple KB page may be of interest for those who go that route.

• Removing Paths/ Landing Pages From SharePoint Search Results

  - by j.strugnell

  Hi there, We've been asked by a client to remove a number of pages from being shown up in their public website search results page. I've been into the SSP and created Crawl Rules to remove these pages. All seemed to have worked ok but we have an issue in that landing pages are still showing up in their "www.domain.com/sitearea/" form but not in their "www.domain.com/sitearea/pages/default.aspx". For each of this type of page we have created one rule to "Exclude" the "aspx" path and another rule to include the "/" path but to "Follow links on the URL without crawling the URL itself". We tried adding rules to exclude the "/" format but that only resulted in all results underneath that being excluded. Does anybody know how to remove the "area/pages/default.aspx" and the "area/" pats from Search Results? I'm not sure if it's the "done thing" to ask 2 questions in one but this is in a similar vein so it should be ok. I was wondering if anyone knew of a tool (or if it is possible) to allow site admins to exclude pages from search results (not via SSP/Crawl Rules). I know they can do it at the site level but I was wondering if anything out there enabled this to be done at the page level through either Page or Site Settings?

• Windows server administration over web browser

  - by Andras Sebestyen

  I wonder if there is a software which can control Windows server over a browser. I know it sounds is strange however I haven't seen any and as you can do scripting with *nix system I think it could be a good one. Functions that I am after: User management Printer install msi assign I know there are many programmes including a win server but I would like to do it only one surface. Has anyone come a cross such a thing like this?

• Lighttpd + django on gentoo 10 seconds to answer

  - by plaetzchen

  I want to run a Django site on a lighttpd with fastcgi on a gentoo machine. Everytime I try to access the site I get a response after more or less exactly 10 seconds. Im using a socket to let lighttpd communicate with my Django site, but a tcp port doesn't help either. Could this be a lighttpd problem? I tried to both from a server in the internet as well as from localost, this is what lighttpd gives me in the error.log 2012-07-10 14:36:36: (response.c.300) -- splitting Request-URI 2012-07-10 14:36:36: (response.c.301) Request-URI : / 2012-07-10 14:36:36: (response.c.302) URI-scheme : http 2012-07-10 14:36:36: (response.c.303) URI-authority: owntube 2012-07-10 14:36:36: (response.c.304) URI-path : / 2012-07-10 14:36:36: (response.c.305) URI-query : 2012-07-10 14:36:36: (response.c.300) -- splitting Request-URI 2012-07-10 14:36:36: (response.c.301) Request-URI : /owntube.fcgi/ 2012-07-10 14:36:36: (response.c.302) URI-scheme : http 2012-07-10 14:36:36: (response.c.303) URI-authority: owntube 2012-07-10 14:36:36: (response.c.304) URI-path : /owntube.fcgi/ 2012-07-10 14:36:36: (response.c.305) URI-query : 2012-07-10 14:36:36: (response.c.349) -- sanatising URI 2012-07-10 14:36:36: (response.c.350) URI-path : /owntube.fcgi/ 2012-07-10 14:36:36: (mod_access.c.135) -- mod_access_uri_handler called 2012-07-10 14:36:36: (mod_fastcgi.c.3632) handling it in mod_fastcgi 2012-07-10 14:36:36: (response.c.470) -- before doc_root 2012-07-10 14:36:36: (response.c.471) Doc-Root : /var/www/owntube 2012-07-10 14:36:36: (response.c.472) Rel-Path : /owntube.fcgi 2012-07-10 14:36:36: (response.c.473) Path : 2012-07-10 14:36:36: (response.c.521) -- after doc_root 2012-07-10 14:36:36: (response.c.522) Doc-Root : /var/www/owntube 2012-07-10 14:36:36: (response.c.523) Rel-Path : /owntube.fcgi 2012-07-10 14:36:36: (response.c.524) Path : /var/www/owntube/owntube.fcgi 2012-07-10 14:36:36: (response.c.541) -- logical -> physical 2012-07-10 14:36:36: (response.c.542) Doc-Root : /var/www/owntube 2012-07-10 14:36:36: (response.c.543) Rel-Path : /owntube.fcgi 2012-07-10 14:36:36: (response.c.544) Path : /var/www/owntube/owntube.fcgi

• Php5-fpm Crash if much visitors

  - by chillah

  I decided to change my OP to Nginx from Litespeed because i read much about the low resource that Nginx would cost. Im running a Wordpress site with 500 users online My www.conf in "/etc/php5/fpm/pool.d" pm.max_children = 200 pm.start_servers = 20 pm.min_spare_servers = 20 pm.max_spare_servers = 60 ;pm.process_idle_timeout = 10s; ;pm.max_requests = 1000 Since i changed that config to higher requests and more children the Site needs longer till it shows me a White blank page. If i restart the php5-fpm prozess then, the site is running fine again. The CPU usage is at 5% if the php5-fpm is crashed and if its running its about 20 to 90%! Heres my Nginx.conf: user www-data; worker_processes 2; pid /var/run/nginx.pid; events { worker_connections 3048; # multi_accept on; } http { ## # Basic Settings ## sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 65; types_hash_max_size 2048; # server_tokens off; I already tried changing the settings, tryed all variants but nothing worked.

• Reverse Proxy issues IIS on Windows Server 2012

  - by ahwm

  I've tried searching, but nothing seems to be working. I have a feeling it might be due to our custom Rewrite module. Here is the excerpt from the web.config that sets it up: <modules runAllManagedModulesForAllRequests="true"> <add name="UrlRewriteModule" type="EShop.UrlRewriteModule"/> </modules> EShop.UrlRewriteModule is a custom class in App_Code which handles incoming requests. I have set up the rewrite rules but it doesn't seem to want to work. I'm inclined to think that our rewrite class is interfering earlier than the proxy rules and saying that the page doesn't exist. Here's what we're trying to accomplish: We are working on a new site for a client, but they have a forum that they're not likely to want to move. I set up a new subdomain to point to the new server while the site is being completed (before we go live) and want the reverse proxy to forward test.domain.com/forum to www.domain.com/forum. After the site goes live, we'll need to forward using an IP address instead. I've set up a reverse proxy successfully with nginx, but we didn't want to set up another server if we didn't need to. Ideas?

• VPS goes slow at more than 20 users online at the same time

  - by hachiari

  I have 512 MB VPS (brustable to 1GB) Somehow, the site goes slow when there are about 10 users, and becomes impossible to load at 20 users online at the same time. I wonder what could be the problem for this. The bandwidth connection of the VPS is 1Gbps.

This is a serious problem :( my site just cant grow if this keeps on happening... please tell me if you have any idea. Thank You, Bryant

• default domain and first domain in apache2 causing trouble

  - by acidzombie24

  I have 3 sites and a default/test site using mono's test page. I created aFirst, c, d, e, zLast. zLast has rewrite rules that should be evaluated last. Since the first VirtualHost seen is the default i set it to this --aFirst-- <VirtualHost *:80> ServerName www.domain.tld ServerAdmin webmaster@localhost DocumentRoot /var/www/test DirectoryIndex index.html index.aspx index.php MonoDocumentRootDir "/var/www/test" MonoServerPath rootsite "/usr/local/bin/mod-mono-server2" MonoApplications rootsite "/:/var/www/test" <Directory /var/www/test> MonoSetServerAlias rootsite SetHandler mono AddHandler mod_mono .aspx .ascx .asax .ashx .config .cs .asmx </Directory> </VirtualHost> The problem is my default page (the ip address of my server) and the first website (csite.ddomain.net) have problems (even though csite is defined in c and is not the first virtual host). The ip address of my server and csite.ddomain.net ALWAYS load the same site. Either monos test page or the csite. It flips every time i restart apache. Why isnt the server ip address always loading the default page (mono test page) and why isnt csite.ddomain.net always loading the site i want!?! Heres the config for --csite-- <VirtualHost *:80> ServerName csite.testdomain.net ServerAdmin webmaster@localhost ServerAlias s.csite.testdomain.net DocumentRoot /var/www/prjname DirectoryIndex index.html index.aspx MonoDocumentRootDir "/var/www/prjname" MonoServerPath rootsite "/usr/local/bin/mod-mono-server2" MonoApplications rootsite "/:/var/www/prjname" <Directory /var/www/prjname> MonoSetServerAlias rootsite SetHandler mono AddHandler mod_mono .aspx .ascx .asax .ashx .config .cs .asmx </Directory> </VirtualHost> aFirst, c, d, e, zLast are all enabled.

• How can I setup BluePill to Monitor a Rails App Running via Passenger (mod_rails)

  - by Jim Jeffers

  I recently launched a site running phusion passenger. Unfortunately, the site went down due to a frozen thread. I was able to save the server by doing kill -9 to the specific PID. Still though, I thought passenger was able to manage this automatically. I have a server with 1GB of memory running one rails app with passenger allotted up to 7 instances. However, when I came to discover the site went down I found that passenger had spawned 6 instances with one of them using up over 800mb of memory causing the server to swap. As a result I am hoping to setup something like bluepill on the server but I'm slightly confused as to how you go about doing it. Mainly because bluepill expects to start/stop the processes it's monitoring. However, in our case, passenger already restarts processes for us so we only need to monitor the pids of passengers instances and kill them once they've gotten too large. Has anyone here setup BluePill to monitor a rails app running under phusion's passenger? Any insight would be useful.

• Problem running “Central Administration” website after windows update at Windows 2003 Server Standar

  - by Magdy Roshdy

  I was have WSS 2.0 and then I upgraded to WSS 3.0 and the old instalation database was SQL 2000, now I have another SQL Server instance called:server_name\MICROSOFT##SSEE . After upgrade every thing works fine and our team started to use the portal and we sent lot of documents and make lot of activities on it. The problem started after installing Windows updates the website suddenly stopped and giving me an error "Cannot connect to the configuration database" If I tried to open SharePoint Products and Technologies Configuration Wizard it is gives me a strange error says: "An exception of type Microsoft.SharePoint.PostSetupConfiguration.PostSetupConfigurationTaskException was thrown. Additional exception information: SharePoint Products and Technologies cannot be configured. The current installation mode does not support SKU to SKU upgrades because there exists an older version of Windows SharePoint Services that must be upgraded first " At this post:http://stackoverflow.com/questions/114398/iis-error-cannot-connect-to-the-configuration-database/249494#249494 the guy of the second answer have the same problem and he suggested a solution but I don't understand well. I tried as he suggested to make the identity of the app pool of the SharePoint web site as "IWAM_server_name " after that the error changed as he said and I web site give me "Server Application Unavailable " and when checked the Event Viewer at the server I found that ASP.NET 2.0 give this exception: "Could not load file or assembly 'System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

I hope I will find some one to help me.

• Cisco RV042 VPN with Dynamic IPs - Remote Gateway Not Resolving

  - by Rister

  I have an existing network setup that I inherited from my predecessor. Currently there are two sites, each with a Linksys RV042 VPN router running the 1.3.12.19-tm firmware. They are currently set up with a Gateway to Gateway VPN. One site has a static IP, the other has a Dynamic IP with a hostname set up on no-ip.com. My company is looking to set up another site so I purchased another RV042 only this one was Cisco branded and it is running the latest firmware. I had assumed that I would be able to configure a vpn from our main office (the dynamic ip) to the new site with this router quite easily. However when I set up a new VPN tunnel on either device, it stays on Waiting for Connection and the Remote Gateway shows an ip address of 0.0.0.0 rather than the remote ip address. The other VPN tunnel is still working and I don't see any obvious misconfiguration on the new router. It seems that the router is not resolving the Dynamic DNS address and therefore not giving me the option to connect the VPN. Does a Gateway to Gateway VPN work with Dynamic IP addresses on each end? Are the firmware versions not compatible? Is there something I've missed?

• The suggested way to handle pip(easy_install) with homebrew?

  - by Drake

  I know there are brew-gem and brew-pip but it is still really easy to get confused. Let's say my Mac OS X is 10.7.2. There are at least, as far as I know, 3 locations for Python modules (assume 2.7): /System/Library/Frameworks/Python.framework/Versions/2.7/ /Library/Python/2.7/site-packages /usr/local/lib/python2.7/site-packages/ (controlled within homebrew) For some Python modules, pip install them into 2, the so-called local/customized Python module location, and everything looks and works great. Ex, readline by *easy_install* (ipython suggested me to install readline by *easy_install* instead of pip) For some, it would try to install some miscellaneous files (ex, man, doc, ...) into system-wide location, which requires sudo! Ex, ipython insisted on installing man and doc into /System/Library/Frameworks/Python.framework/Versions/2.7/share/, which violates permission issue and all I can do is to use sudo. For some Python modules installed by brew, they are symbolic linked to /usr/local/lib/python2.7/site-packages/. Everything seems great except that you have to remember to add this location into PYTHONPATH. I am wondering any suggested and uniform way to handle those mass, or any explanation to make those stuff crystal clear.

• Clone Microsoft VM > SharePoint issues

  - by Rob

  Hi, We have an existing (production) Hyper-V VM that I want to clone to create a staging server. This server is NOT on a domain/active-directory - uses all local computer accounts. It is Windows 2008 OS, SharePoint 2007, SQL server 2008, Reporting Services, and some custom line-of-business web-applications. We rename the server etc as per the documentation we have, but are having troubles specifically with SharePoint. Some of the sites do not come up, and some issues adding/updating site settings such as site owners. Does anyone know of a definitive resource to this process? thanks Update: We seem to have most working, but the Shared Service Provider, and the SSP's admin site, are not working. In addition, the custom web-parts that reference IIS Session objects are failing (which seem to be related to the Share Service Provider). All the Windows user accounts for various services are renamed during the server cloning, but the windows account names in SQL server are not automatically changed. We've tried to change them in SQL server but still does not seem to work Seems like allot of work - and am thinking that there must be some guidance out there. also getting this: NullReferenceException: Object reference not set to an instance of an object.] Microsoft.Office.Server.Administration.SqlSessionStateResolver.System.Web. IPartitionResolver.ResolvePartition(Object key) +135

• I just got a virus 6 mins ago, how? Situation.

  - by acidzombie24

  -Edit- for the people who say it isn't a virus. Norton does detect it as a virus, an icon was placed on my system tray and rkpg.exe is in my C: which was placed 6 min ago around the time my computer rebooted on its own causing me to lose data :@. Situation I on Windows XP, behind a Linksys router, I don't have DMZ on so nothing should be connecting to me. I had Firefox, MSN and Visual Studio opened. With C# I programmed a quick application to scan some pages with Internet Explorer. The site it was scanning was deviantART (which is pretty trustworthy), I doubt any banners there would hold a virus. I went to a suspicious site called freetxt.com but that was on Firefox and it didn't load the site. With an extra check I ping it and got this message "Ping request could not find host freetxt.com." The virus seems to be called braviax. Right now it brought up a message saying my computer may be infected? How on earth did it get in? I don't have uTorrent installed or any torrent or p2p applications. Nothing is installed on my computer that I haven't installed before and I know the exact time it installed because I see rkpg.exe on my C drive and my computer restarted on its own around the same time. For the previous 30 minutes actually the previous hour all I did was talk on MSN, not click any links (I went to freetxt on my own) and had that Internet Explorer thing running (which I programmed). How did it get in? I really doubt it came from a banner on deviantART and installed when I loaded the page with the webbrowser-control so something else may have happened? Is there any system defaults I should turn off? I have remote assistance off but even if it was on I shouldn't be infected due to the router not forwarding any ports?

• Managing SharePoint permissions via Active Directory?

  - by rgmatthes

  My company has thousands of employees organized thoroughly via Active Directory. I have confidence in the accuracy of the Department and Title information displayed in the user profiles. I'm helping to put up a brand new SharePoint 2007 site, and I contacted IT about managing the site's permissions through AD Groups. The goal is to have the site automatically assign read/write/contribute/whatever permissions based on the information in AD. For example, we could create an AD Group called "Managers" that would contain anyone with the "Manager" title in their AD user profile. I would have SharePoint tap into this AD Group to mass assign permissions if I knew all managers would need a certain level of access (read/write/contribute/whatever). Then if a manager joins the company or leaves it, the group is automatically updated (provided AD gets updated, of course). My IT rep called back and said it couldn't be done. This seems like a pretty straightforward business requirement, and one of the huge benefits of having Active Directory, but maybe I'm mistaken. Could anyone shed some light on this? A) Is it possible to use dynamically-updated AD Groups when assigning permissions via SharePoint? (Does anyone know of a guide I could show my doubtful IT rep?) B) Is there a "best practice" way to go about this? I've read some debate on whether SharePoint Groups or AD Groups are the way to go. My main concern is dynamic updating. C) If this isn't available out of the box, can someone recommend third-party software that will provide the functionality I'm looking for? A big thanks to anyone who can help me out!!

• Automake thumbnail

  - by Webmaster

  What I need to do is a program that given (as a command line argument) a directory with more directoreies inside, and 4 Pics inside of each dir, the program makes a thumbnail of the 4 files and glues them together (2 rows, 2 columns) and renames that image to the name of the directory. I think it could be done with a combination of a program and shell scripting (I'm experienced in M$, but new to linux). Some real examples would be great. Thanx in advance

• How to avoid compressing compressed files

  - by Gzorg

  Most compression programs compress all files by default. But when archiving a folder containing already compressed files, there is no need to compress them a second time, such as archives, packed setup program, jpg, movies, mp3,.... Are there any compression programs that allow an arbitrary list of type of files to be stored while the others are still compressed ? It looks like Winrar can't. I expect this would be doable with tar+gz/bzip2 and some scripting in various ways. Edit : Winrar can

• Dealing with upgrade of libevent on Amazon AWS

  - by Dreen

  I am building an application (in Python) on Amazon EC2 that has a following dependency chain: gevent-websocket ---> gevent ---> libevent The last one (libevent) got upgraded on Sunday and my server is now generating this error: (...) File "/usr/lib/python2.6/site-packages/gevent-0.13.7-py2.6-linux-x86_64.egg/gevent/__init__.py", line 41, in <module> from gevent import core ImportError: libevent-1.4.so.2: cannot open shared object file: No such file or directory Not wanting to spend much time on the issue, I tried to mitigate it by creating a symlink to an always-recent version: $ sudo ln -s /usr/lib64/libevent.so /usr/lib64/libevent-1.4.so.2 But it didn't quite work: (...) File "/usr/lib/python2.6/site-packages/gevent-0.13.7-py2.6-linux-x86_64.egg/gevent/__init__.py", line 41, in <module> from gevent import core ImportError: /usr/lib/python2.6/site-packages/gevent-0.13.7-py2.6-linux-x86_64.egg/gevent/core.so: undefined symbol: current_base I am a bit stumped as to how to proceed. Should I create more symlinks? To what? Or is there a better way to solve this problem... PS. For the record I am using Amazon AMI.

• How to save a remote server SSL certificate locally as a file

  - by Kimvais

  I need to download an SSL certificate of a remote server (not HTTPS, but the SSL handshake should be the same as Google Chrome / IE / wget and curl all give certificate check fail errors) and add the certificate as trusted in my laptops Windows' certificate store since I am not able to get my IT guys to give me the CA cert. this is for office commnunicator so I cannot really use the actual client to get the cert. How do I do this, I have Windows 7 and a pile of Linuxes handy so any tool / scripting language is fine.
