Installation of MAC OSx86 in VMware (Windows)

Saturday, November 15, 2008
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.

VSFTPD "500 oops cannot change directory"

Friday, September 12, 2008
Today, I am trying to configure FTP server in my virtual Linux box.After the installation and configuration, am not able to change the directory itself. It displays the message"500 OOPS CANNOT CHANGE DIRECTORY", when i was trying to change the directory.

After searching Google, I found the solution for this. It is pretty simple, I have disabled the SELinux and ran this command

"/usr/bin/setsebool -P ftp_home_dir 1 "

This solved my issue.

Sunday, May 25, 2008
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

Tuesday, May 20, 2008
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

Monday, February 25, 2008

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)

Types of DNS records

Friday, February 8, 2008
Important categories of data stored in the DNS include the following:

* An A record or address record maps a hostname to its 32-bit IPv4 address.

* An AAAA record or IPv6 address record maps a hostname to its 128-bit IPv6 address.

* A CNAME record or canonical name record makes one domain name an alias of
another. The aliased domain gets all the subdomains and DNS records of the original.

* An MX record or mail exchange record maps a domain name to a list of mail
exchange servers for that domain.

* A PTR record or pointer record maps an IPv4 address to the canonical name for that host. Setting up a PTR record for a hostname in the in-addr.arpa domain that corresponds to an IP address implements reverse DNS lookup for that address. For example (at the time of writing), www.icann.net has the IP address 192.0.34.164, but a PTR record maps 164.34.0.192.in-addr.arpa to its canonical name, referrals.icann.org.

* An NS record or name server record maps a domain name to a list of DNS servers for that domain. Delegations depend on NS records.

* An SOA record or start of authority record specifies the DNS server providing authoritative information about an Internet domain.

* A SRV record is a generalized service location record.

* A TXT record allows an administrator to insert arbitrary text into a DNS record. For example, this record is used to implement the Sender Policy Framework specification.

Other types of records simply provide information (for example, a LOC record gives the physical location of a host), or experimental data (for example, a WKS record gives a list of servers offering some well-known service such as HTTP or POP3 for a domain).

Windows Offline Files Synchronization Issue

Tuesday, February 5, 2008
In my client desktop (XP), I found some error and warning messages during system log-off.
The error messages are :-
1. Files of this type cannot be made available offline.
2. Unable to made archive1.PST file available offline

Then, I verified and reinitialized the CSC (Client Side caching) database files by the following procedure.

1. In Folder Options, on the Offline Files tab, press CTRL+SHIFT, and then click Delete Files. The following message appears:
The Offline Files cache on the local computer will be re-initialized. Any changes that have not been synchronized with computers on the network will be lost. Any files or folders made available offline will no longer be available offline. A computer restart is required.

Do you wish to re-initialize the cache?

2. Click Yes two times to restart the computer.

After I created a new offline CSC database and start synchronization.
Issue Solved !!

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
