  • Load testing nginx inside AWS

    - by andy
    I'm trying to load test nginx running on AWS. I need to try to optimise it to handle 1Gbps of inbound traffic. Currently I've got it to peak at 85Mbit/s by running nginx on an m1.large with 4 other machines hitting it by using ab with -i (for head requests) -k (keepalives) -r (ignore failed requests) -n 500000 -c 20000. I'm struggling to generate more than 85 Mbit/s traffic from 4 machines, yet when I do scp a large file I get nearly 0.25Gbit/s of traffic going over the network. Are there any tools or approaches that I could use to load test nginx that might generate more load? I'm only interested in inbound traffic, so perhaps a DoS tool could help if it chucks away responses? I'm hitting a very small (40 byte) static asset, and have peaked at handling 50K concurrent connections and getting 25k reqs/s when just using a single load generator machine.

  • Wpf application variable not changing

    - by Hasan Zubairi
    In my application I need some variables on almost all the pages so I declared them in Application.xaml like <sys:String x:key="First">First</sys:String> and on one page I change the value in code like Resources["First"] = "This is First"; on the second page when I call the variable like String f = (string)this.TryFindResource("First"); MessageBox.Show(f); the out put is "First" and not "This is First". I also tried like. Application.Current.Properties["First"]

  • Python subprocess.Popen hangs in 'for l in p.stdout' until p terminates, why?

    - by Albert
    I have that code: #!/usr/bin/python -u localport = 9876 import sys, re, os from subprocess import * tun = Popen(["./newtunnel", "22", str(localport)], stdout=PIPE, stderr=STDOUT) print "** Started tunnel, waiting to be ready ..." for l in tun.stdout: sys.stdout.write(l) if re.search("Waiting for connection", l): print "** Ready for SSH !" break The "./newtunnel" will not exit, it will constantly output more and more data to stdout. However, that code will not give any output and just keeps waiting in the tun.stdout. When I kill the newtunnel process externally, it flushes all the data to tun.stdout. So it seems that I can't get any data from the tun.stdout while it is still running. Why is that? How can I get the information? Note that the default bufsize for Popen is 0 (unbuffered). I can also specify bufsize=0 but that doesn't change anything.

  • VPN/Proxy server to bypass work proxy

    - by Trevor
    Here is my dilema, I am at work and can not set up a VPN connection to my VPN account in the USA. So what I would like to do is somehow have my "IE" at work connect to my home network and route any internet requests through my home PC to my VPN account, so I can access my USA Contents? So what I was thinking and I am not sure if this will work, but set up a proxy server at home on my home computer, that then routes all requests to my VPN Tunnel to the USA. Have my work computer use my home computer as the proxy and viola I have unrestricted internet access? Does that sound feasable? Thanks.

  • IIS + PHP + Page with lots of images = Intermittent 403 errors

    - by samJL
    I am using an up-to-date Server 2008 R2 Datacenter, running IIS 7.5 and PHP 5.3.6/FastCGI On PHP pages with lots of images (60+), some of the images fail to load It is not always the same images-- on each page refresh an image that worked previously may not load, while an image that did not now does Looking at the Net tab in Firebug reveals that the failing image requests are 403 errors All of the images are located on the server in question, and the images directory has the correct permissions I believe this problem is the result of a limit on requests All of my attempts at researching this problem point to maxConnections setting in IIS, yet mine is set at the highest/default of 4294967295 (maxBandwidth too) I am also running a ColdFusion site on the same IIS installation, and it does not suffer from 403's on pages with lots of images I am left thinking that there is another connection limit (in PHP or FastCGI?) overriding the IIS connection limit I don't see anything that looks like a request limit in the php.ini, what am I missing? Any help would be appreciated, thank you

  • What exactly is an invalid HTTP_HOST header

    - by rolling stone
    I've implemented Django's relatively new allowed hosts setting, which is meant to prevent attackers from submitting requests with a fake HTTP Host header. Since adding that setting, I now get anywhere from 20-100 emails a day notifying me of invalid HTTP_HOST headers. I've copied in an example of a typical error message below. I'm hosting my site on EC2, and am relatively new to setting up/maintaining a server, so my question is what exactly is happening here, and what is the best way to manage these invalid and I assume malicious requests? [Django] ERROR: Invalid HTTP_HOST header: 'www.launchastartup.com'.You may need to add u'www.launchastartup.com' to ALLOWED_HOSTS.

  • Identifying a function call in a python script line in runtime

    - by Dani
    I have a python script that I run with 'exec'. The script's string has calls to functions. When a function is called, I would like it to know the line number and offset in line for that call in the script (in the string I fed exec with). Here is an example. If my script is: foo1(); foo2(); foo1() foo3() And if I have code that prints (line,offset) in every function, I should get (0,0), (0,8), (0,16), (1,0) In most cases this can be easily done by getting the stack frame, because it contains the line number and the function name. The only problem is when there are two functions with the same name in a certain line. Unfortunately this is a common case for me. Any ideas?

  • Restarting or stopping apache results in waiting forever

    - by steko
    I have two simple WSGI apps running on top of mod_wsgi and apache2 on a test development server. There is no mod_python on this machine. The WSGI configuration is as follows WSGIDaemonProcess tops stack-size=524288 maximum-requests=5 WSGIScriptAlias /tops /home/ubuntu/tops-cloud/tops.wsgi <Directory /home/ubuntu/tops-cloud> WSGIProcessGroup tops WSGIApplicationGroup %{GLOBAL} Order deny,allow Allow from all </Directory> WSGIDaemonProcess flaskal maximum-requests=5 WSGIScriptAlias /c14 /home/ubuntu/c14/flaskal/flaskal.wsgi <Directory /home/ubuntu/c14/flaskal> WSGIProcessGroup flaskal WSGIApplicationGroup %{GLOBAL} Order deny,allow Allow from all </Directory> If I make changes to the app, I need to restart the web server, so I would expect that a simple sudo service apache2 restart does what I need. Same goes for any changes to the config (e.g. number of maximum requests, etc). Instead, it never ends "waiting", like this: $ sudo service apache2 restart * Restarting web server apache2 ... waiting .................................................. until I just do CTRL-C. At that point, the only way to resume a working server is to kill the process and restart it, not very convenient. The same happens with the stop command. The error logs at the "debug" level show the following lines after a failed restart [Wed Nov 14 21:55:19 2012] [notice] caught SIGTERM, shutting down [Wed Nov 14 21:55:19 2012] [info] mod_wsgi (pid=9047): Shutdown requested 'tops'.

If I then try to restart again (with the process still running), I get the following error: * Restarting web server apache2 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs Action 'start' failed. The Apache error log may have more information. Unfortunately the Apache error log doesn't have anything. When apache2 is running properly, both apps work without any problem.

  • Sun Directory Server 5.2 performance

    - by tmow
    Hi all, I'm using logconv.pl (provided by Sun), to measure performance on my server. These two metrics results, are worrying me a bit: Binds: 192164 Unbinds: 111569 In fact the difference between the two it's quite big, how can I determine which are the unbound requests? As stated by Lodovic: Many applications just close the connections without sending an Unbind request. This simply can explain the difference. But the logconv.pl doesn't show details about the unbound requests, do you know any other tools or can you suggest some queries or whatever that can help me find out the root cause? Do you think anyway that the performances may improve fixing the issue?

  • How to allow Hudson build URL through Nginx auth_basic?

    - by rodreegez
    Hi, I have Hudson running and made available to the world via nginx. I have protected Hudson with nginx's auth_basic and that works great. The trouble is, I want to allow unauthenticated requests to the build URL, i.e. /job/<job_name>/build. Currently I have this in my nginx conf: upstream hudson { server 127.0.0.1:8888; } server { server_name ci.myurl.com; root /var/lib/hudson; location / { proxy_pass http://hudson/; auth_basic "Super secret stuff"; auth_basic_user_file /var/opt/hudson/htpasswd; } location ~ \/build { auth_basic off; } } I can't get that second location to allow unauthenticated requests. I have tried various combinations of location ~ /job/(.*)/biuld { } location ^~ \/build { } location ~ \/job\/(.*)\/build { } etc... Maddening! Can anyone point me in the right direction? Thanks, Ad.

  • Process is killed without a (obvious) reason and program stops working

    - by Krzysiek Gurniak
    Here's what my program is supposed to do: create 4 child processes: process 0 is reading 1 byte at a time from STDIN, then writing it into FIFO process 1 is reading this 1 byte from fifo and write its value as HEX into shared memory process 2 is reading HEX value from shared memory and writing it into pipe finally process 3 is reading from pipe and writing into STDOUT (in my case: terminal) I can't change communication channels. FIFO, then shared memory, then pipes are the only option. My problem: Program stops at random moments when some file is directed into stdin (for example:./program < /dev/urandom). Sometimes after writing 5 HEX values, sometimes after 100. Weird thing is that when it is working and in another terminal I write "pstree -c" there is 1 main process with 4 children processes (which is what I want), but when I write "pstree -c" after it stopped writing (but still runs) there are only 3 child processes. For some reason 1 is gone even though they all have while(1) in them.. I think I might have problem with synchronization here, but I am unable to spot it (I've tried for many hours). Here's the code: #include <unistd.h> #include <fcntl.h> #include <stdio.h> #include <string.h> #include <stdlib.h> #include <sys/shm.h> #include <sys/sem.h> #include <sys/types.h> #include <sys/wait.h> #include <sys/stat.h> #include <string.h> #include <signal.h> #define BUFSIZE 1 #define R 0 #define W 1 // processes ID pid_t p0, p1, p2, p3;

  • Nginx https rewrite turns POST to GET

    - by x7311
    My proxy server runs on ip A and this is how people access my web service. The nginx configuration will redirect to a virtual machine on ip B. For the proxy server on IP A, I have this in my sites-available server { listen 443; ssl on; ssl_certificate nginx.pem; ssl_certificate_key nginx.key; client_max_body_size 200M; server_name localhost 127.0.0.1; server_name_in_redirect off; location / { proxy_pass http://10.10.0.59:80; proxy_redirect http://10.10.0.59:80/ /; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } server { listen 80; rewrite ^(.*) https://$http_host$1 permanent; server_name localhost 127.0.0.1; server_name_in_redirect off; location / { proxy_pass http://10.10.0.59:80; proxy_redirect http://10.10.0.59:80/ /; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } The proxy_redirect was taken from how do I get nginx to forward HTTP POST requests via rewrite? Everything that hits the public IP will hit 443 because of the rewrite. Internally, we are forwarding to 80 on the virtual machine. But when I run a python script such as the one below to test our configuration import requests data = {'username': '....', 'password': '.....'} url = 'http://IP_A/api/service/signup' res = requests.post(url, data=data, verify=False) print res print res.json print res.status_code print res.headers I am getting a 405 Method Not Allowed. In nginx we found that when it hit the internal server, the internal nginx was getting a GET request, even though in the original header we did a POST (this was shown in the Python script). So it seems like rewrite has problem. Any idea how to fix this? When I commented out the rewrite, it hits 80 for sure, and it went through. Since rewrite was able to talk to our internal server, so rewrite itself has no issue. It's just the rewrite dropped POST to GET. Thank you! (This will also be asked on Nginx forum because this is a critical blocker...)

  • Linux server, locating files containing nothing but 4 specific lines.

    - by Denis
    Hi, I'm dealing with a compromised website, in which hackers injected an htaccess instruction to redirect traffic. I can easily locate .htaccess files that contain the forwarding hack, BUT in cases where the directory already contained an htaccess file, they appended the dangerous instructions, so I cannot just deleted any htaccess file or could harm the site by letting formerly pw-protected directories wide open, or urlrewrite instructions (WordPress) be deleted, etc. I could not find the way to locate files that only contain those 4 lines of redirect hack, could you shed some light ? So far, using find . -type f -exec grep -q targetpiratedomain {} \; -exec echo rm {} \; Thanks !

  • Accepted date format changed overnight

    - by Eugene Niemand
    Since yesterday I started encountering errors related to date formats in SQL Server 2008. Up until yesterday the following used to work. EXEC MyStoredProc '2010-03-15 00:00:00.000' Since yesterday I started getting out of range errors. After investigating I discovered the date as above is now being interpreted as "the 3rd of the 15th month" which will cause a out of range error. I have been able to fix this using the following format with the "T". EXEC MyStoredProc '2010-03-15T00:00:00.000' By using this format its working fine. Basically all I'm trying to find out is if there is some Hotfix or patch that could have caused this, as all my queries using the first mentioned formats have been working for months. Also this is not a setting that was changed by someone in the company as this is occurring on all SQL 2005/2008 servers

  • Google App Engine dev_appserver can't find PIL (I've installed it)

    - by goggin13
    I recently upgraded my Google App Engine launcher on my Mac, running OSX 10.5.8, and afterwards my projects that work with images stopped working locally. It seems to be the same problem that I had when first using GAE locally to work with images, before I installed PIL. Here is the error I get: SystemError: Parent module 'PIL' not loaded I have PIL installed. When I run python normally, I can access it and work with it as expected. I also checked to ensure that dev_appserver.py was running the same version of Python. If I open the interpreter and type sys.version I get this back: 2.5 (r25:51918, Sep 19 2006, 08:49:13) [GCC 4.0.1 (Apple Computer, Inc. build 5341)] This is identical to what I get when I display the sys.version from my projects running through dev_appserver. Any thoughts on why dev_appserver can't find the PIL module? I have been banging my head against this for a bit. Thank you!

  • SSL on app - nginx web server

    - by Adam
    I am running an nginx web server where I redirect all http requests to https (with a self signed cert). Here is how I REDIRECT all http requests to https in the nginx config file: server { listen 80 default_server; listen [::]:80 default_server ipv6only=on; server_name my.server.ip; return 301 https://$server_name$request_uri; Problem is - I cannot seem to do so for an app running on a port. Example: http://my.server.ip:1234 does not redirect to https://my.server.ip:1234 ir works fine on all other urls like http://my.server.ip/temp etc. How can I modify the nginx config file to force that app url through ssl?

  • PyQt signal between QObjects

    - by geho
    I'm trying to make a view and controller in PyQt where the view is emitting a custom signal when a button is clicked, and the controller has one of its methods connected to the emitted signal. It does not work, however. The respond method is not called when I click the button. Any idea what I did wrong ? import sys from PyQt4.QtCore import * from PyQt4.QtGui import QPushButton, QVBoxLayout, QDialog, QApplication class TestView(QDialog): def __init__(self, parent=None): super(TestView, self).__init__(parent) self.button = QPushButton('Click') layout = QVBoxLayout() layout.addWidget(self.button) self.setLayout(layout) self.connect(self.button, SIGNAL('clicked()'), self.buttonClicked) def buttonClicked(self): self.emit(SIGNAL('request')) class TestController(QObject): def __init__(self, view): self.view = view self.connect(self.view, SIGNAL('request'), self.respond) def respond(self): print 'respond' app = QApplication(sys.argv) dialog = TestView() controller = TestController(dialog) dialog.show() app.exec_()

  • Mac OSX 10.8 Server DNS Domain Routing

    - by Oldek
    I just cant seem to figure out the logic in how to configure my Mac Server. So I have set up an DNS, which will take the domain and all subdomains and point towards an IP. File: db.mydomain.com (in /var/named/) mydomain.com. 10800 IN SOA mydomain.com. admin.mydomain.com. ( 2012110903 ; serial 3600 ; refresh (1 hour) 900 ; retry (15 minutes) 1209600 ; expire (2 weeks) 86400 ; minimum (1 day) ) 10800 IN NS mydomain.com. 10800 IN A 10.0.1.2 www.mydomain.com. 10800 IN A 10.0.1.2 So I want all of these requests to be requested to the 10.0.1.2 server, as I run 2 servers in my cluster. This one has always handled the requests, and now I want to add a server in between. So the server in between will get all the signals from my router which NAT the trafic coming from outside. So after setting this up and trying to point my port 80 towards my new server which will be the middle point, it doesn't work. Is it even possible to do it this way? First server: Mac Second server: Linux So what I try to achieve once more: 1. User goes to mydomain.com or www.mydomain.com 2. User request gets handled by my first server 3. First server refers to a local server, which is only available locally (it is configured to allow requests on port 80 and handle them) 4. Second server receives signal 5. Second server returns a request (either directly send to user or send through first server, whichever is most secure and configurable) I also want to be able to set up domains that lead to other servers in the future, and some that are only available within the VPN. (If that changes anything) I hope some kind soul could help me with this, it is really cumbersome for my mind to get the logic here. Do I have to configure my other server in any way? /Marcus

  • How to use a value from one stored procedure in another?

    - by RoguePlanetoid
    I have the following statement in a Stored Procedure: DECLARE @Count INT EXEC @Count = GetItemCount 123 SELECT @Count Which calls another stored procedure with the following statement inside: SELECT COUNT(Item) FROM tblItem WHERE ID = @ID However when I test the call the EXEC outputs the value correctly but it is not assigned to the @Count Variable correctly. I've seen examples or stored procedures used like this, including here but none had a parameter and a return value used (that I could find). The ID Parameter is passed into the second statement which returns a count value used by the first StoredProcedure - all the info I have read seems to indicate this should work - but it doesn't the @Count value is aways zero, even when the GetItemCount returns always the correct value. This is in Microsoft SQL Server 2008 if that helps.

  • Would this rollback/stop all records from inserting?

    - by chobo2
    Hi I been going through this tutorial http://www.codeproject.com/KB/linq/BulkOperations_LinqToSQL.aspx and them make a SP like this CREATE PROCEDURE [dbo].[spTEST_InsertXMLTEST_TEST](@UpdatedProdData nText) AS DECLARE @hDoc int exec sp_xml_preparedocument @hDoc OUTPUT,@UpdatedProdData INSERT INTO TBL_TEST_TEST(NAME) SELECT XMLProdTable.NAME FROM OPENXML(@hDoc, 'ArrayOfTBL_TEST_TEST/TBL_TEST_TEST', 2) WITH ( ID Int, NAME varchar(100) ) XMLProdTable EXEC sp_xml_removedocument @hDoc Now my requirements require me to mass insert and mass update one after another. So first I am wondering can I merge those into one SP? I am not sure how it works with this OPENXML but I would think it would just be making sure that the XPath is right. Next what happens while it would be running this combined SP and something goes wrong. Would it roll back all the records or just stop and the records that happened before this event that crashed it would be inserted?

  • Assign the results of a stored procedure into a variable in another stored procedure

    - by RHPT
    The title of this question is a bit misleading, but I couldn't summarize this very well. I have two stored procedures. The first stored procedure (s_proc1) calls a second stored procedure (s_proc2). I want to assign the value returned from s_proc2 to a variable in s_proc1. Currently, I'm calling s_proc2 (inside s_proc1) in this manner: EXEC s_proc2 @SiteID, @count = @PagingCount OUTPUT s_proc2 contains a dynamic query statement (for reasons I will not outline here). CREATE dbo.s_proc2 ( @siteID int, @count int OUTPUT ) AS DECLARE @sSQL nvarchar(100) DECLARE @xCount int SELECT @sSQL = 'SELECT COUNT(ID) FROM Authors' EXEC sp_ExecuteSQL @sSQL, N'@xCount int output', @xCount output SET @count = @xCount RETURN @count Will this result in @PagingCount having the value of @count? I ask because the result I am getting from s_proc1 is wonky. In fact, what I do get is two results. The first being @count, then the result of s_proc1 (which is incorrect). So, it makes me wonder if @PagingCount isn't being set properly. Thank you.

  • Architectural advice - web camera remote access

    - by Alan Hollis
    I'm looking for architectural advice. I have a client who I've built a website for which essentially allows users to view their web cameras remotely. The current flow of data is as follows: User opens page to view web camera image. Javascript script polls url on server ( appended with unique timestamp ) every 1000ms Ftp connection is enabled for the cameras ftp user. Web camera opens ftp connection to server. Web camera begins taking photos. Web camera sends photo to ftp server. On image url request: Server reads latest image on hard drive uploaded via ftp for camera. Server deleted any older images from the server. This is working okay at the moment for a small amount of users/cameras ( about 10 users and around the same amount of cameras), but we're starting to worrying about the scalability of this approach. My original plan was instead of having the files read from the server, the web server would open up an ftp connection to the web server and read the latest images directly from there meaning we should have been able to scale horizontally fairly easily. But ftp connection establishment times were too slow ( mainly due to the fact that PHP out of the ox is unable to persist ftp connections ) and so we abandoned this approach and went straight for reading from the hard drive. The firmware provider for the cameras state they're able to build a http client which instead of using ftp to upload the image could post the image to a web server. This seems plausible enough to me, but I'm looking for some architectural advice. My current thought is a simple Nginx/PHP/Redis stack. Web camera issues post requests of latest image to Nginx/PHP and the latest image for that camera is stored in Redis. The clients can then pull the latest image from Redis which should be extremely quick as the images will always be stored in memory. The data flow would then become: User opens page to view web camera image. Javascript script polls url on server ( appended with unique timestamp ) every 1000ms Camera is sent an http request to start posting images to a provided url Web camera begins taking photos. Web camera sends post requests to server as fast as it can On image url request: Server reads latest image from redis Server tells redis to delete later image My questions are: Are there any greater overheads of transferring images via HTTP instead of FTP? Is there a simple way to calculate how many potential cameras we could have streaming at once? Is there any way to prevent potentially DOS'ing our own servers due to web camera requests? Is Redis a good solution to this problem? Should I abandon PHP/Ngix combination and go for something else? Is this proposed solution actually any good? Will adding HTTPs to the mix cause posting the image to become too slow? Thanks in advance Alan
