  • Apache reaching MaxClients and locking the server

    - by Rodrigo Sieiro
    Hi. I currently have an Apache2 server running with mpm-prefork and mod_php on a OpenVZ VPS with 512M real / 1024M burstable RAM (no swap). After running some tests, I found that the maximum process size Apache gets is 23M, so I've set MaxClients to 25 (23M x 25 = 575 MB, ok for me). I decided to run some load tests on my server, and the results left me puzzled. I'm using ab on my desktop machine requesting the main page from a wordpress blog. When I run ab with 24 concurrent connections, everything seems fine. Sure, CPU goes up, free RAM goes down, and the result is about 2-3s response time per request. But if I run ab with 25 concurrent connections (my server limit), Apache just hangs after a couple of seconds. It starts processing the requests, then it stops responding, CPU goes back to 100% idle and ab times out. Apache log says it reached MaxClients. When this happens, Apache keeps itself locked up with 25 running processes (they're all in "W" if I check server status) and only after the TimeOut setting the processes start to die and the server starts responding again (in my case it's set to 45). My question: is that expected behaviour? Why Apache just dies when it reaches MaxClients? If it works with 24 connections, shouldn't it work with 25, just taking maybe more time to respond each request and queueing up the rest? It sounds kinda strange to me that any kid running ab can alone kill a webserver just by setting the concurrent connections to the servers MaxClients.

  • Connecting to VPN via Proxy

    - by Rodrigo
    Hi, My company's VPN server is located in Netherlands, from my current location this is a really crappy place in terms of connectivity, connection keeps dropping, it's slow and keeps being reset during high traffic times. I have a dedicated server over USA which is able to connect to VPN server without this issues, connection is stable and fast. My question is, how do I connect to this VPN using a proxy running on my dedicated server? I'm on Windows 7 using a VM on XP to connect to the VPN. Thanks.

  • Tomcat Clustering and Load Balancing ?

    - by Rodrigo Asensio
    I have 3 tomcat servers where users get into all time. They are 3 because the processing of each request is heavy (lot of sql). Users enters to server 1 or 2 or 3. Now I want to make them "one". I know I need do clustering but, will clustering spread the requests thru the 3 servers or here is where I need implement load balancing with apache2 ?

  • Mail server hammering

    - by Rodrigo
    I've noticed a quick increase on smtp connections coming to my server, investigating it further i figured out that there's a botnet hammering my smtp server. I've tried to stop it by adding a rule at iptables: -N SMTP-BLOCK -A SMTP-BLOCK -m limit --limit 1/m --limit-burst 3 -j LOG --log-level notice --log-prefix "iptables SMTP-BLOCK " -A SMTP-BLOCK -m recent --name SMTPBLOCK --set -j DROP -A INPUT -p tcp --dport 25 -m state --state NEW -m recent --name SMTPBLOCK --rcheck --seconds 360 -j SMTP-BLOCK -A INPUT -p tcp --dport 25 -m state --state NEW -m recent --name SMTP --set -A INPUT -p tcp --dport 25 -m state --state NEW -m recent --name SMTP --rcheck --seconds 60 --hitcount 3 -j SMTP-BLOCK -A INPUT -p tcp --dport 25 -m state --state NEW -j ACCEPT That would avoid them from hammering "too fast", however the problem still, there's like 5 tries per second, it's going insane, i had to incrase the maximum number of childs of sendmail/dovecot. There's too many ips to filter out manually and simply changing the smtp to another port is not practical since i got many other clients on that server. I'm using sendmail with dovecot, any ideas to have this filtered out more efficiently?

  • Is there a way to import a scheduled task from windows 2003 (.job) to windows 2008 (.xml)?

    - by Rodrigo
    I had some jobs to be moved from the old production server (windows 2003 server standard) to the new machine (windows 2008 server standard), but the new server is unable to read the old .job format, also the import wizard only imports from .xml job files (same version). Obviously I don't want to rebuild all the jobs by hand, but can't find a tool that makes the process a very little easier. I don't trust in Microsoft for this kind of tools, my previously experiences had been to bad (DTS - SSIS). Any ideas? Thanks in advance.

  • Building a generic page "Query Analyzer" like in Asp.net with SMO

    - by Rodrigo
    Hello, I'm build a web page in ASP.net is supposed to work just like Query Analyzer. It has basically a textarea to input the sql command, and an Execute button. I'm using SMO to execute the command in the database, as follows: //Create object SMO Microsoft.SqlServer.Management.Smo.Server server = new Microsoft.SqlServer.Management.Smo.Server(new Microsoft.SqlServer.Management.Common.ServerConnection(oConn)); //To execute the command server.ConnectionContext.ExecuteNonQuery(tbx_cmd.Text); //OR myDataset = server.ConnectionContext.ExecuteWithResults(tbx_cmd.Text); The problem is that the textarea command can contain anything, from a stored procedure (with GO's statements) and any select command that return resultsets, just like Query Analyzer. But, if I have GO statements, I only can perform the query using ExecuteNonQuery method. If I use the ExecuteWithResults method, it raises errors because of the GO statements. And if I want the resultsets to be available, of course I can only use the ExecuteWithResults method. Does anybody knows how can I do to execute the same command texts at the same time? Thank you!

  • Floating DIV's alignment problem.

    - by Rodrigo
    I have a fluid layout with DIV's of different heights and widths, and I'd like them to be aligned by lines, kind of like when you do a search on istockphoto, except aligned to the top: image here--http://i207.photobucket.com/albums/bb121/jpbanks/Capturadepantalla2010-06-02alas1902.png I tried floating all the DIV's to the left, but they are not aligned correctly into lines: image here--http://i207.photobucket.com/albums/bb121/jpbanks/Capturadepantalla2010-06-02alas1900.png See how "Prueba" doesn't go all the way to the left? I thought of the jQuery plugin Masonry but what I want is obviously different. Any solution using either CSS or jQuery would be fine. Any ideas?

  • How to get the "real" colors when exporting a GDI drawing to bmp

    - by Rodrigo
    Hi guys I'm developing a ASP.Net web handler that returns images making a in-memory System.Windows.Forms.Control and then exports the rendered control as a bitmap compressed to PNG, using the method DrawToBitmap(). The classes are fully working by now, except for a problem with the color assignment. By example, this is a Gauge generated by the web handler. The colors assigned to the inner parts of the gauge are red (#FF0000), yellow (#FFFF00) and green (#00FF00) but I only get a dully version of each color (#CB100F for red, #CCB70D for yellow and #04D50D for green). The background is a bmp file containing the color gradient. The color loss happens whether the background is a gradient as the sample, a black canvas, a white canvas, a transparent canvas, even when there is not a background set. With black background With transparent background With a white background Without a background set With pixel format in Format32bppArgb I've tried multiple bitmap color deeps, output formats, compression level, etc. but none of them seems to work. Any ideas? This is a excerpt of the source code: Bitmap bmp = new Bitmap(w, h, System.Drawing.Imaging.PixelFormat.Format32bppPArgb); Image bgimage = (Image) HttpContext.GetGlobalResourceObject("GraphicResources", "GaugeBackgroundImage"); Canvas control_canvas = new Canvas(); .... //the routine that makes the gauge .... control_canvas.DrawToBitmap(bmp, new Rectangle(0, 0, w, h));

  • ASP.NET MVC Binding - Duplicated Messages

    - by Rodrigo Gama
    I'm using ASP.NET MVC Binding Framework. Let's say I have a class Item, that has a mandatory field Id. I am binding a List, and do not want one error message for each element in this list. If more then one error happen when binding the Id field, I want only one message to be added to ModelState and shown to the user. In one sentence: Is there a way to avoid duplicated messages using ASP.NET MVC Binding Framework?

  • What happens with TCP packets between two Socket.BeginReceive calls?

    - by Rodrigo
    I have a doubt about socket programming. I am developing a TCP packet sniffer. I am using Socket.BeginAccept, Socket.BeginReceive to capture every packet, but when a packet is received I have to process something. It is a fast operation, but would take some milliseconds, and then call BeginReceive again. My question is, what would happen if some packets are sent while I am processing, and haven't called BeginReceive? Are packets lost, or are they buffered internally? Is there a limit?

  • How to flush data in php and disconnect user but keep the script alive

    - by Rodrigo
    This is a trick question, while developing a php+ajax application i felt into some long queries, nothing wrong with them, but they could be done in background. I know that there's a way to just send a reply to user while throwing the real processing to another process by exec(), however it dosen't feels right for me, this might generate exploits and it's not pratical on making it compatible with virtual servers and cross platform. PHP offers the ob_* functions although they help on flushing the cache, but the user will keep connected until the script is running. I'm wondering if there's an alternate to exec to keep a script running after sending data to user and closing connection/thread with apache, or a less "dirty" way to have processing data sent to another script.
