Apache :: Windows - How To Configure 1 Process Per Client
Sep 19, 2014
I've got a quite difficult problem which I don't know hoe to solve. We use a self created ISAPI module which is a "business server" running behind an Apache.
From time to time a client app crashes the server (the circumstances are not quite clear) - and because there is only one server process, all other clients crash as well. Here is an exemplary log of a crash:
Faulting application name: httpd.exe, version: 2.2.22.0, time stamp: 0x4f242d7a
Faulting module name: ABCServer.dll, version: 1.0.0.1, time stamp: 0x53cfffa5
Exception code: 0xc00000fd
Fault offset: 0x00004cf6
Faulting process id: 0x94c
Faulting application start time: 0x01cfc5cc18c67d57
Faulting application path: C:Program Files (x86)Apache Software FoundationApache2.2inhttpd.exe
Faulting module path: C:datawwwabcremoteABCServer.dll
Report Id: d27d5891-31da-11e4-93ff-0003ff4356f9
Faulting package full name:
Faulting package-relative application ID:
Exception code: 0xc00000fd means stack overflow as I learnt. Therefore we configured mpm_winnt_module to use a 8M ThreadStackSize but this didn't work.
A solution might be that Apache starts for every client its own server process with the module ABCServer.dll. Because it is quite small and there are not thousands of customers this sounds like the perfect solution. No other clients/customers would be affected by a crash.
Unfortunately mpm_winnt_module supports only 1 process AFAIK. Worker and Prefork MPM are not available in Apache's Windows version what I read.
How can we configure Apache to start a new module process per client?

i want to configure Apache so that it receives a client certificate, an passes it to another server.I'm using:
- apache 2.0.65 on windows
- the backend server is an apache-based solution (IBM HTTP Server)
I tried this config:
<VirtualHost *:443>ServerName apacheserver.domain.comSSLEngine onSSLProxyEngine onSSLCertificateFile "e:/Apache/Apache2/conf/server.cer"SSLCertificateKeyFile "e:/Apache/Apache2/conf/server.key"SSLCACertificateFile "e:/Apache/Apache2/conf/certca.cer"SSLVerifyClient requireSSLVerifyDepth 2ProxyPreserveHost onProxyRequests off<Proxy *>AddDefaultCharset

Between our Linux servers, I can get speed up to 80Mbps when transferring big files. However, between Linux and Windows, it's just around 800Kbps - 2Mbps. It shows in network connection properties that connected at 100Mbps, but not sure why it's so slow
Is there any setting I should pay attention? Running Windows 2003 on that box.

Ive recently installed installed and configured stuff on my new box but after, I realised abnormal memory usage.
Mysql server is taking 256mb, there are somewhere between 6 and 10 apache process taking up at least 40mb each.
Furthermore, when I do: top, I see that the memory usage is increasing by about 120ko each 3 sec.
I am running centos 5.1 and have a load of 0. Basically, there is no one on the server appart from me.
On the server I have at home running debian, I run all thoose thing and it take up 200mb
max.

I got dedicated server with Windows Server 2k3 OS and have not configured it yet. I've installed Serv-U and Apache 2 (PHP, MySQL will be the next step). But I can't open my Website from home (from server there is no problems). And I can't get into my FTP server either. I scanned ports from home to figure that out. 21 for FTP is seen. 80 http is not seen. However on the server I did "netstat -an" and it showed the port 80 listening. So why can't I reach my FTP server and open my site? Is the problem in Windows Server 2k3 configuration?

I have an unmanaged Windows VPS and I want to host multiple sites (with different domains).
I was told that I should create my own private nameservers in order to do so.
I have allready installed DNS Server in the VPS but I cannot find a tutorial to help me configure the private nameservers.
The OS is Windows Server 2003. Please provide any good tutorials if you know.
I searched in Google but couldn't find any...

From the remote server i can log into FTP from the command line and use WinSCP to login using sftp with no problem. When i try going through the repository page it just hangs. I have tried the passiv option as well. Is seems to hang at the LIST -a command. Here is the cerberus log below.

(I am using apache 2.2.25).I have this "HTML5 and CSS all in one for dummies" Book. And it tells me I have to configure the .conf file to make apache work with PHP.
At this point I have only edited the Document root folder. The book tells me to find a Loadmodule with an # with a mention of PHP (I'll put the text of the book at the end) and to add an "addtype" statement. If have found neither and when I add the manually the server doesnt work.how can I make PHP work? Also, I have noticed that the Apache commands in CMD don't work. I am running windows 8.1. URL....

I'm working on a script to automatically install apache. Now, after the apache configure/make/make install I need to test for a successful completion. I checked the configure options but there is no flag for an unsuccessful finish.I would like to know if there is any other way than to test the command output for a successful or unsuccessful ending? I'm saving the output on a file and then grepping for an expected line. For example "creating test/ Makefile" for the configure.

I am in a bind with Apache's multi process limit. Let me explain what I am doing. There's this website which has career details of all the football players since the beginning of professional football. They have a simple web form which allows you to look at a player's profile by entering his name or his 7 digit numeric id number (on that website).
One of my client wants a list of all the players with a certain "flag" in their profile. So I created an automatic form submission and HTML parsing script to get details of all the players with that "flag" in their profile. Let me not go into too much details and tell you that after applying a few pattern rules to the id number, the number of possible id numbers comes to about 1 million (instead of 10^7; each field can have {0,1,2,3,4,5,6,7,8,9}=10 digits, so net combinations = 10*10*10*10*10*10*10).
Therefore, to completely automate this process I wrote a script which would generate an id number, submit the form with that id number, and parse the resulting HTML profile for the "flag". If the script finds a hit on the flag, it stores all the fields of that player in a database. This script is working absolutely fine but the speed I was getting was about one check per second which means that I would have to leave the script running for about 11 days (to process all of about 1 million checks).
So i came up with this idea to divide the check into ten parts and i created separate scripts for each part. Now basically the first script checks for the first 100 thousand combinations, the second checks for another 100 thousand combinations, and so on.
The problem is that I am able to get only two of these scripts running at the same time. So it would still take me at least 5 days to get all the results. The rest of the scripts just sit there in the server's backlog. This is definitely due to Apache's limitation to handle multiple processes. The server I am using to run this script as well the target webserver both run on Apache2. I am sure it's not a problem with the receiving server. It has to be my Apache web server which is running the scripts. I have tried using mpm_winnt (on a windows server) as well as the prefork and worker modules (on a linux server) without any luck. Has any of you ever faced the same situation?
For those concerned about the legitimacy of this work, rest assured, this is absolutely legit. There's nothing in the website's use policy which restricts somebody from doing this. Moreover, my client hired me to do this only because the website owners were not able to hand over the data he required. They gave the stupid reason that they are helpless in providing the data because they don't have a system in place which would allow them to do a search restriction!

I recently switched from XAMPP to a self-setup WAMP installation using Apache Lounge's 2.4.9 package in order to improve performance, to have more tweaking possibilities and to solve some problems that I was not able to solve in XAMPP (e.g. creating large PDF files using TCPDF) on my local Windows 7 development PC.PHP is running as FCGI module, which I thought was a good idea to achieve good performance, but I am afraid I have messed up the configuration a bit.
What happens is that sometimes, PHP script requests do not seem to terminate(?), but I do neither know why, nor do I know what is happening. It probably has something to do with scripts that process kind of a larger

Is there a way to configure the mailing lists created with Plesk (using MailEnable 6.5) using Plesk or another web interface like it is possible with mailman under Linux?
It is not very convenient to be required to do such stuff via RDP (and so manual by me for every customer)...

Unlike earlier versions of Microsoft Windows Server, the 2008 version gives you a default logon screen that is very similar to Vista. Instead of the the interactive dialog box that prompts you for a username, password, and sometimes domain, users will find a “push button” screen displaying all users with login permissions. To log into an account all the users will now need to know is the password. This makes things much easier for hackers as the only thing they will now need to guess is the password.
There are a couple of ways to resolve this problem. First, the server administrator can set the local security policy to not display the last username and disable fast user switching. Second, in the System Remote Settings dialog, the remote desktop options can be set to allow computers with Remote Desktop that support Network Level Authentication.
Since the first method is covered in a few blogs, I’ll limit myself to discussing the second method. In the latest versions of Remote Desktop Connection client (version 2.0 for Mac and the version shipped with Windows Vista), Network Level Authentication is supported. This means users must send the username and password before Windows 2008 accepts the connection. Earlier versions of RDC (like the one found in many installations of Windows XP) don’t support NLA. So technically, users will only need to supply the IP or domain name of the remote Windows server, leave the username and password blank, and interact with the logon process that is provided at connection time. Windows 2008 servers that do not have the NLA option set for remote desktop connections are vulnerable since the interactive logon screen (post-connection) is displayed to users using earlier versions of RDC.
This last point may be of significance to service providers offering Windows 2008 dedicated servers. If the server is set up with default settings, the NLA option is disabled and new users will by default be made to change passwords on first logon. Users using new versions of RDC will not be able to logon because the initial password change sequence on first logon is not compatible with NLA. The server will return an incorrect password message to the RDC client even though the user has provided the correct username and password. The only way to establish first connection is thus to use a non-NLA supporting version of RDC so that the user can establish connections without supplying credentials and then going through the password change wizard during the initial login. But as mentioned, having NLA disabled on server side is not an ideal practice at this point.
So there are a couple ways to do this. The service provider should disable the “change password on next logon” option during the user creation process and get user to manually change the password after logon. Or alternatively, assist the client/user in changing passwords through the console internally.
