Installation of MAC OSx86 in VMware (Windows)

Last two days, I tried to install MAC OS 10.4.9 in windows VMware after i got to know that MAC OSx86 was able to run on Windows (Intel) machine.I found many sites do guide the installation of Mac OS x86. There are various way to install the OSx86 but what i want to show here is a very simple installation with the use of VMware 6.

Firstly, you must have the following files & software before you start your Mac OSx86 installation:

1. tiger-x86 image file. [tiger-x86.tar.bz2]
2. VMware Workstation. [ I'm using VMware Workstation 6
3. Minimum 6 Gigabytes hard disk space.

INSTRUCTIONS:
Step 1: Install VMware Workstation into your PC.

Step 2: Extract “tiger-x86.tar.bz2″ file into any folder. You can use WinRAR to perform the extraction. Please remind that the data files from “tiger-x86.tar.bz2″ is 6 gigabytes size. So please make sure you extract it into a sufficient free space hard disk drive and the hard disk partition format/type is NTFS.
( if your partition is FAT32 or older format, you will be facing extraction error because FAT32 supports a single file size up to 4 gigabytes only. [ I encounter this problem twice before i get to solve this. my stupidity.. :P]

Step 3: After everything is ready & VMware is installed, launch the VMware Workstation now.

Step 4: Now select “New Virtual Machine” icon or go to menu “File”->”New”->”Virtual Machine”.

Step 5: At first dialog screen, click “Next”. In “Virtual machine configuration”, select“custom” and click “Next” button.

Step 6: For “Virtual machine format”, select “New-Workstation 5″ and click “Next” button.

Step 7: When asking about “Select a Guest Operating System”, select “Other” from the radio button. And Select “Other” also from the drop down list of “Version” selection.

Step 8: In “Name the Virtual Machine”, you are about to name your virtual machine name and select the location of your virtual machine. You can give any name for the virtual machine but i chose “Tiger” as the name. Now, “Browse” to the folder that contains the extracted files of tiger-x86 image [tiger-x86.tar.bz2]. Your folder should have following files: floppy.flp, tiger-x86.nvram, tiger-x86.vmdk, tiger-x86.vmsd, tiger-x86.vmx, tiger-x86-flat.img, and some .log files.

Step 9: After select the location of the folder, click on “Next” button. You will be seeing a message dialog box about “…Having two virtual machines installed in the same location can cause problem…”. Just click “Yes” from the message box.

Step 10: Now you will have to specify the amount of memory allocated to the virtual machine. If you have large memory in your PC, you can allocated more to the virtual machine else i would recommend to allocated at least “Recommended memory” size [green pointer] from the dialog box. Just click on “Next” button again once you specified the amount of memory.

Step 11: In “Network Connection” options, choose “Do not use a network connection” for now and click “Next” button.

Step 12: In “I/O adapter” types, select “Buslogic” from SCSI Adapters.

Step 13: Now you will see the “Disk” dialog box, select the second option, “Use an existing virtual disk” and click “Next” button.

Step 14: After you chose to use an existing virtual disk, you are required to select “the existing disk file”. Thus, just browse to the extracted folder and select the virtual machine disk file. The filename is “tiger-x86.vmdk”. After select the file, just click on “Finish” button. Then the message box will totally disappeared from the screen now but the VMware Workstation is still there. Don’t worry.

Step 15: Mac OS Tiger x86 is ready to launch now. Just select “Start Virtual Machine” from “Tiger” virtual machine or click on the Green Arrow button ( PLAY button) on the top left corner of the VMware.

CONGRATULATIONS!! You shall enjoy your Mac OS Tiger x86 in your VMware now.

Setting up network between host and guest machines in VMWare

I am using Windows XP Host and have installed VMWare for Linux RHEL 5 which will be the Guest operating system.I will get the request timed out error When am trying to ping the IP address of host machine from Guest machine and vice versa.

After Googling, I found the solution and now am able to ping or connect between the host and guest machines.

The problem is quite simple.By default, i have selected the VMWare network configuration as NAT settings.After that, I have changed the settings to Bridge Networking.

Now it's Working fine...........

SQL Service Access Denied

Today, am having a problem in windows server 2003 SQL database server.Actually, I have two database engine in my server, one is Server/MSFW (Firewall) and another one is Server/SQLEXPRESS.

The server/MSFW database engine has started and connecting perfectly without issues. But, the other one Server/SQLEXPRESS has not started and unable to start manually from SQL Configuration manager and Services.msc. It gave the error message in event viewer is

"UpdateUptimeRegKey: Operating system error 5(Access is denied.)"

Finally, I found the solution on Google :

In Services.msc, Double click on the Service which one you faced issue (Server/SQLEXPRESS) and then click on the 'Log On' tab. Change the 'Log on as' option from 'This account...' to 'Local system account'.

Types of Proxies

There are several types of proxies. Proxy of each type is designed to solve its specific tasks, however they have much in common, and their abilities coincide in many features.

HTTP Proxy

It is the most widespread type of proxy servers and when you hear just "proxy", it means nothing, but this type of a server. Earlier with a help of this proxy it was only possible to view web pages and pictures and download files. Now, new program versions (ICQ, etc.) know how to work through the HTTP proxies. Browsers of any versions know how to work with this type of proxy.

SOCKS Proxy

These proxy servers know how to work practically with any type of information on the Internet (TCP/IP protocol), however for their use in programs there should be obviously indicated a ability to work with SOCKS proxy. Some additional programs are necessary for using of SOCKS proxies within a browser (browsers do not know how to work through SOCKS proxy). However, any ICQ versions (and many other popular programs) can work perfectly through the SOCKS proxies. At last, we want to pay attention, while working with socks proxies it is necessary to specify its version: socks 4 or socks 5.

CGI Proxy (anonymizer)

This type of proxy server could be accessed only with a browser. In other programs their using is complicated (and one does not need it, there are HTTP proxies). However as this type proxy is initially designed for operation through a browser, one can use it in a very simple way. Moreover, you can construct a chain from CGI proxies without any problems.

FTP proxy

This type of proxies is highly specialized and aimed for work only with FTP servers. You can use these proxies in most popular file managers (FAR. Windows Commander, etc.), download managers (CuteFTP, GetRight, etc.) and in browsers.

ISA Server 2006 Issue

Today morning, I am unable to access the internet from ISA server itself. And from the client cannot access ISA server.

In IE, I got a message “The ISA server denied the specified Uniform resource Locator”
Actually am a newbie of ISA concept. So, I learn some basics of ISA and firewall rules thru Google. Finally I sorted out these issues.

After installing the ISA server 2006, we have to create two outbound firewall chain rules for accessing external network as well as internal.

Two rules as follows:-
1. To allow all outbound connections from local host and internal to External network (This for internet access)

2. To allow all outbound connections from local host and internal to internal and local host network (This for internal network access)

VPN Server Deployment

Yesterday, I have worked on VPN server deployment in our office. We are planning to use our windows server 2003 as a VPN server.

But In our windows server 2003, we have only single NIC.

So, I have deployed VPN server according to single NIC. The procedure as follows

1. Configured RRAS server for single NIC
2. Enable Router to forward PPTP packets (1723)
3. Create a VPN client

After established the VPN connection, the VPN client not able to ping or communicate to the RRAS server. So, I Google it and found the following useful information.

Cannot reach beyond the RRAS server from VPN clients?

Many a time we face this issue - after making a VPN connection to the Routing and Remote Access server, we are unable to reach the machine on the network behind the VPN server. Here are a few tips to troubleshoot this.

Let's consider this example to understand this well.

VPN Client <---Internet---> RRAS server <----------------> LAN client

Static pool configured on RRAS server: 10.0.0.1 - 10.0.0.10 [This means that the VPN clients will get a 10.0.0.X address from this pool]

Public interface of RRAS server to which clients connect: 65.54.46.9

Private interface of RRAS server: 192.168.0.4 (The LAN clients on this network will have addresses 192.168.0.X)

We want to reach the LAN client 192.168.0.16 from the VPN client 10.0.0.2. The following are the things that we need to ensure for this

(1) Need to have proper routes on the VPN client to reach the machines behind the RRAS server

For our example, on the VPN client we need to have a route to reach the LAN client i.e. for 192.168.0.16 as the destination with the VPN server (10.0.0.1) as the gateway as follows.

route add 192.168.0.0 mask 255.255.255.0 10.0.0.1 if

This route makes sure that any packet destined to the LAN clients will go out through the PPP adapter of the client to the server's internal interface. As the RRAS server has one interface on the same network as the LAN client, it will route it accordingly to the LAN client.

On the VPN client side, a default route can also be added which can be used to reach the internet [otherwise even internet requests will go through the RAS server].

This concept is called split- tunneling and is explained in the below article. http://www.microsoft.com/technet/community/columns/cableguy/cg1003.mspx

(2) Need to have correct routes on the LAN clients behind the RRAS server for the VPN clients

The packet from the VPN client will reach the LAN client if the route on VPN client is proper which is ensured by (1) above.
However, for the packet from LAN client to reach the VPN client, we should have correct routes on the LAN client too. For example, when you try to ping 192.168.0.16 from the VPN client, the routes on the VPN client will aid in the echo request to reach 192.168.0.16.

However, for the echo reply from 192.168.0.16 to reach the VPN client, you LAN client should have a route for the VPN client with gateway as the private interface of RRAS server as follows:

route add 10.0.0.0 mask 255.255.255.0 192.168.0.4 if

This way, the echo reply destined to 10.0.0.2 will reach the RRAS server which is the next hop according to the above route. Once it reaches the RRAS server, the server knows how to send it to the client as it will have a route for all clients conencted to it.

Note: On the LAN clients, a reverse route can be added individually on all the clients or all LAN clients may be pointing to some router which then can have a reverse route for 10.0.0.0 network OR RRAS server itself can be the default router for LAN clients

Dynex Webcam Issue - Black screen

One of my project manager faced the black screen issue in dynex webcam.He asked me to solve this issue.I gooogle and find out the simple solution.The solution is below.

I know this camera has had a bit of a bad rap, but I'm here to clear all that up. After getting it set up right after some research, I found this webcam to be a nice & neat gadget. The video & picture qualities are somewhat more refined than the Microsoft VX-3000 (which I own as well). And the mic on the camerca works fine as long as the echoes are cleared out (which happens to all mics once in a while).

I strongly recommend this camera to anyone looking for a nice lil webcam with multi-functionality with a low price tag.

For direction on getting beyond the black screen:

I realized that 99% of customers (PC) have problems getting beyond the black screen so here's the step by step instruction on on to set your Dynex DX-DTCAM correctly.

1.) Without plugging in the webcam, install the driver directly from the CD-ROM
2.) Now plug in the webcam into the USB, and Windows will say "new device detected"
3.) Click the advanced option in wich you can choose the drivers folder. Then on the next window you click on the *manually choose* option.
4.) You will see the Dinex drivers appear, select it and install.

DO NOT UPDATE DRIVERS FROM THE DYNEX SUPPORT SITE. It's useless & will confuse the hardware.

Remote Desktop Connection ( RDC ) Port Forwarding

Yesterday,I unable to access my remote desktop via RDP (Remote Desktop Protocol), I got an error message "Unable to find the remote server".

After that, i checked the both Remote Desktop properties and internet properties, but no luck.

Finally i Google and found the port forwarding is not done in our router.

Then i enabled the following port in router

Application or Description field: RDC
Port Range Start: 3389
Port Range End: 3389
Protocol Type: TCP & UDP

Prevent Group Policy Settings from applying to administrator

Typically, if you want Group Policy to apply only to specific accounts (either user accounts, computer accounts, or both), you can put the accounts in an organizational unit and then apply Group Policy at that organizational unit level. However, there may be situations where you want to apply Group Policy to a whole domain, but you may not want those policy settings to also apply to administrator accounts or other specific users or groups. The following procedure can prevent Group Policy from applying to administrative accounts (or any other group or user account you specify) by editing the Access Control List (ACL) for the policy:

1.	Click Start, point to Administrative Tools, and then click Active Directory Users and Computers.
2.	In the left console tree, right-click the name of the domain where the policy is applied, and then click Properties.
3.	Click the Group Policy tab.
4.	Click the group policy object that you do not want to apply to administrators. By default, the only policy that is listed in the window is the Default Domain Policy.
5.	Click Properties, and then click the Security tab. If the group or user who you do not want policies to apply does not appear in the list, use the following procedure: a. Click Add. b. Click the domain where the account resides. c. Find the account, and then click it in the list. d. Click OK. Continue with the remaining steps.
6.	Click the administrators group (or other group or user) that you do not want the policy to apply to.
7.	In the Permissions windows, click to select the Deny check box for the Apply Group Policy permission. This prevents the group policy object from being accessed and applied to the selected group or user account.

Setup Windows XP Backups & Scheduled Tasks

Recommended Backup Schedule:

* Four (4) days a week: Run a DAILY DIFFERENTIAL BACKUP. A DIFFERENTIAL backup will backup only those files that have been created or modified since your last NORMAL backup.
* One (1) day a week: Run a WEEKLY NORMAL BACKUP. A NORMAL Backup will backup ALL your selected files and mark them as backed up.

How long will backups take to run and what is the impact on my computer?

Daily differential backups will take a shorter time to run than your normal full backup since this backs up only modified and new files. Depending on how many files are involved this backup may only take a few minutes. You should be able to work normally on your computer, but may notice a slight slow down.

Weekly normal full backup will of course take longer since it backs up all your selected files and will hold more data. Again, how much data you have will determine how long. If you have 2GB or less of data the backup should take less than one hour. During this time you may notice a slow down in computer performance. So, you may want to schedule this during a time when you are not using your computer.

Windows 2003 IIS Server - Permission Error

Problem

If the Web based Install will not start and you have installed to Windows 2003 Server, an error like the one below can occur.

Access to the path "C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\Temporary ASP.NET Files\acb\1a6d1ed3fe0f4362" is denied.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.UnauthorizedAccessException: Access to the path "C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\Temporary ASP.NET Files\acb\1a6d1ed3fe0f4362" is denied.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via , the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

Solution

The Asp.Net user needs read/write permissions to this directory. This is the temp directory .net uses for the compiled files.

The default installation of .Net doesn't appear to give itself rights to a directory it needs.

In Windows Server 2003, the ASPNET account does not exist. ASP.NET in IIS6 uses the "NETWORK SERVICE" account instead. Add the permissions using that account, as directed in the error message text posted below.

To grant ASP.NET write access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
