How to launch a process with CPU affinity set

SanthoshOnline — Thu, 24 Nov 2011 10:43:15 GMT

I was trying to get this internet explorer process launched so that it can use only 4 processors on a 8 core machine. It wasnt as easy as I thought initially.

Finally I figured out an easy way and I am sure it will save a lot of time for others who require to do this.

There are few different methods we can do this.

1st Method

System wide we can set the boot.ini setting to use /numproc=4 so that the machine uses only 4 cores irrespecitve of the number of cores available (provided the available cores is more than 4)

2nd Method

Launch a command window and run the highligted commands from the next steps
Run cd c:\program files (x86)\internet explorer
Run start /affinity F iexplore.exe
Now you can check the affinity from the task manager OR process explorer.

If you are using start /affinity, you will need to specify the value for affinity which is a hexadecimal value. Here is a simple way of calculating this affinity value.

Here is how the processors will be numbered. This may be different based on the number of nodes. However the calculation remains the same. Please use terms cores/processors interchangeably.

CPU ID	Associated value (n)	Formula (2ⁿ-1)	Affinity in Hex (h)
CPU0	1	1	1
CPU1	2	3	3
CPU2	4	7	7
CPU3	8	15	F
CPU4	16	31	1F
CPU5	32	63	3F
CPU6	64	127	7F
CPU7	128	255	FF

Based on the above formula, you can run the following command. Replace h with the value in the Affinity column. This will result in using all the CPU’s listed above the specified value including the current.

Example:

If you specify a value of 1F for affinity, it will use CPU4, CPU3, CPU2, CPU2 and CPU0

If you want to use specific CPU’s, you will need to SUM the associated values and use the corresponding HEX value.

Example:

If you want to run a process on CPU0 & CPU4, you can sum the values

Start /affinity h iexplore.exe

Enjoy launching processes with CPU affinity :)

How to prevent IIS 6.0 from revealing internal address

SanthoshOnline — Thu, 14 Apr 2011 15:45:08 GMT

I have come across an interesting issue where the internal ip address is revealed when using OPENSSL and HTTP 1.0. However if we use HTTP 1.1 then IIS does not reveal the address.

Here is what happens when I use the OPENSSL

openssl s_client -connect 10.x.y.z:443

GET /Test
Document Moved

Object Moved

This document may be found hereread:errno=0">https://10.x.y.z/Test/">hereread:errno=0

How to prevent this?

You will need to host header on the website that you have issues with. You have to set the host header using the adsutil.vbs script as follows.

cscript c:\inetpub\adminscripts\adsuitl.vbs set w3svc//SecureBindings ":443:myhostname"

Make sure the host header that you set here, eg:myhostname is resolving to the ip adress of the IIS and you can browse the secured website using the specified host header.

Note: is the numeric value that you can obtain from the IIS6 Manager.

Important: If you make changes to the host header from the IIS manager, you may have to re-run the above command.

Setting the host header using the IIS manager on Secure Bindings does not yield any good results. Setting through the above command should be the way.

After the host header is set, you will see the results similar to the following

GET /Test

Bad Request (Invalid Hostname)

read:errno=0

HowTo: WinInet ETW logging (Analytic Logging)

SanthoshOnline — Thu, 08 Jul 2010 13:34:00 GMT

Here is a HowTo on Collecting WinInet Tracing on Windows Vista, Windows 7, Windows 2008 Server and Windows Server 2008 R2. If you require to collect this log, you can enable this log just before the issue and disable soon after the repro, that will provide more information. Here are the screenshots for enabling this.

1) Open Event Viewer and Select Applications and Services Logs and then Click on View Menu, Check the “Show Analytic and Debug Logs”.

2) Under Applications and Services Logs, expand Microsoft and then Windows

3)

4) Under Windows, Select WinInet and expand. Then right click on the Analytic and Select Enable Log.

5)

6) Then select “Disable Log” and save all events to a file in evtx format or .csv for easy viewing.

7)

By default the size of the buffer is set to 1028KB. I would suggest that this value be increased to 25MB just to make sure we don’t end up overwriting the information because of a small buffer.

HowTo: netTcpBinding on IIS and things to remember

SanthoshOnline — Thu, 01 Jul 2010 15:19:40 GMT

Configuring netTcpBinding on IIS requires IIS7. You can refer the article for more information on platform dependencies.

Requirements to get netTcpBinding on IIS7 work.

Make sure the following service in the services snap-in are started

Here is the configuration on the IIS –> Website –> Site Bindings

We need to add a net.tcp binding for 808:*

Here is the settings required on the application under IIS. The name of my sample application is NTLMWCFService. The EnabledProtocols needs to be set to net.tcp.

***NOTE* net.tcp must be in lower case as shown here. ***

Application pool settings on IIS7.

NOTE: If you are using netTcpBinding along with wsHttpBinding on IIS7 with application pool running in Classic Mode, you may notice the “Server Application Unavailable” errors. This happens if the first request to the application pool is served for a request coming over netTcpBinding. However if the first request for the application pool comes for a http resource served by .net framework, you will not notice this issue.

Here is system.serviceModel section for the web.config

WCF: wsHttpBinding with Windows Authentication.

SanthoshOnline — Tue, 29 Jun 2010 12:24:40 GMT

How to configure wsHttpBinding with Windows Authentication:

Here is a simple service configured on IIS with windows authentication. When using wsHttpBinding, the security mode must be “Transport” for Windows Authentication on IIS to be used. Also the website needs to have a server certificate configured.

If you use any other security mode you will receive the following error message.

Security settings for this service require 'Anonymous' Authentication but it is not enabled for the IIS application that hosts this service.

If you are receiving the following error message, make sure the website bindings are configured for https.

Could not find a base address that matches scheme https for the endpoint with binding WSHttpBinding. Registered base address schemes are [http].

SSL Redirection using ASP.NET

SanthoshOnline — Thu, 14 May 2009 21:52:00 GMT

You require ASP.Net configured on IIS to use this solution.

Here is how you can implement this solution.

1) Create a new Virtual Directory “SSLRedirect” and point this to a new physical folder which is independent of your Website Content

2) Created 2 Files in this. 1. Global.asax and 2. Default.aspx

3) Here is the sample code for the Global.asax. Default.aspx can be empty.

<%@ Application Language="VB" %>

Protected Sub Application_BeginRequest(ByVal sender As Object, ByVal e As System.EventArgs)

Try

Response.Redirect(Replace(Replace(Request.Url.ToString.Split(";")(1), "http:", "https:"), ":80", ""))

Catch ex As Exception

System.Diagnostics.EventLog.WriteEntry("SSLRedirect", ex.Message() & _

vbCrLf & Request.UserAgent & _

vbCrLf & Request.UserHostAddress & _

vbCrLf & Request.UserHostAddress)

Response.Write("Goto HomePage")

End Try

End Sub

script>

Note: The exception handling is done to check if the client is directly trying to access the SSLRedirect application and provide the administrators with the client IP who is trying this and then provide with a link for the home page.

4) Now you can goto the properties of the virtual directories or even website that requires to be viewed strictly over SSL and click on Custom Errors and point the 403;4 to the TYPE URL and Contents to /SSLRedirect/Default.aspx.

5) Before you browse the website/virtual directory Make sure the SSLRedirect virtual directory does not have SSL set to required and authentication is set to Anonymous only.

6) Also if you have a web.config not configured for Anonymous access at a parent level to SSLRedirect folder, you will need to have a Web.Config inside the SSLRedirect folder which allows anonymous access.

7) The application configured for the SSL redirection using this method and the SSLRedirect virtual directory both should run under the same application pool.

Get and Set FTP Active Directory Isolation Properties in IIS7 using iisftp.vbs script from IIS6.0

SanthoshOnline — Tue, 31 Mar 2009 00:58:06 GMT

Users who are very used to the iisftp.vbs script in previous version IIS 6.0 can still use it on Windows Server 2008. After all its only a script to Get or Set the FTP AD properties for a given user. The only requirement was it uses the Microsoft.CmdLib component.

When you run iisftp.vbs /? if you get the error as below, you can copy the iisftp.vbs and CmdLib.msc from a Windows Server 2003 machine %windir%\system32\dllcache folder on to your windows 2008 server and register the cmdlib.msc.

Could not create an instance of the CmdLib object.
Please register the Microsoft.CmdLib component.

regsvr32 cmdlib.msc

You can start using the iisftp.vbs after this as you were used to on IIS6.0
