I was creating a photo slideshow VCD in my windows XP using Nero. My Writer drive was not working fine, so i decided to creat the cd image (.nrg) and write it using my Lap installed with Hardy(Ubuntu 8.04) using K3B. K3B didnt accept the nrg file… So going through how to convert the nrg to ISO, I came accross IAT.

IAT is nothing but ISo9660 Analyser Tool. In windows we use many CD Image manipulation softwares
Eg. Alcohol(.mdf), Clone CD(.cdi), Nero (.nrg) and many more. But the standart Image format accepted my all platforms are ISO(.iso).  iat   (Iso9660  Analyzer Tool) is a tool for detecting the structure of many types of CD-ROM image file formats, such as BIN,  MDF,  PDI,  CDI, NRG, and B5I, and  converting them into ISO-9660. Even many Operating System CDs are downloaded in Internet in the same file format. AS it is widely accepted standard. You can install IAT like

~$sudo apt-get install iat

provided your repositories are configured well. Also for the developers the source files can be downloaded in

http://prdownload.berlios.de/iat/

Usage is like

~$iat input_file.nrg output_file.iso

Many laptops, that uses Intel board faces problems with Wlan. That is, most of the time when booted with Ubuntu 8.04 the Wlan will not be enabled and the WirelessLan switch in the laptops will not be of any use… More over the Wireless Lan leds will also be of no use. I faced the same problem and i happened to reboot my ubuntu severall times to get my wlan enabled.

I googled and had a chat in IRC and found it a bug with Ubuntu. Also found the solution as i was surfing. The solution to the above problem is making the WLAN led glow and making the WLAN switch work. For that install the package below using Synaptic or atp-get

linux-backports-modules-hardy

that is install like

~$ sudo apt-get install linux-backports-modules-hardy

Even if it doesnt work after this, install the Latest stable version of ndiswrapper from the link,

http://downloads.sourceforge.net/ndiswrapper

Iam right now using my Dataone connection, in my Lap via wlan as my modem is Wireless enabled. I never reboot now a day to enable my Wlan enabled in my Ubuntu.

If in a Lan, Ping between two system to check the availability of the connection. If peer to peer, connect the lan cable. Assign the IP addresses for the two systems (Like 172.16.25.1 and 172.16.25.2 for both the systems, with subnet mask 255.255.255.0). That is the subnet addresses should be same for both the systems.

scp is the command that can be used for transfering files across the systems. Secure Copy(scp) uses Open SSH protocol for the file transfer. ftp can also be used for the file transfer. For using the scp command you must follow a rule. The rule is, the system you invoke this command should have the ssh client and the target system should have the ssh server(sshd). For copying the files from the source to the destination system, this command can be invoked in both source system or the destination system, but should follow the above rule.

The usage is the scp command is,

#scp username@<source-ip> :/path/to/the/source/file username@<destination-ip> :/path/to/the/destination/file

To copy a folder from the source system to the destination use the recursive the option,

#scp -r username@<source-ip> :/path/to/the/source/folder username@<destination-ip> :/path/to/the/destination/folder

The first user name is the user in the source system and the second username is the user in the destination system. The access privileges to the files or folder to copied or to be used as the destination folder depends on the user privileges used in the command.

When you reinstall your windows in a dual boot system having you windows and ubuntu. Probably you will get a thought that your ubuntu got removed from your hard drive, and you may reinstall you ubuntu also. Thats a waste of time… Your ubuntu will be safe in your Hard drive but the thing is the boot loader doesnt know there is Ubutu in the  hard drive and its location. This is because

This is because, Windows in not more friendly. When you install the Windows it over writes other Boot loaders with its own. Also doesnot identify other Operating systems in the hard drive. Where are opend source boot loaders such as GRUB that come with most of the linus distros are more friendly and detects amost all operating systems.

So to get back your Ubuntu. Just install GRUB (Boot Loader) alone with the help of a Ubuntu cd or dvd, that will take few second than wasting you precious time. Also will give you back the same Ubuntu that you were using before and all softwares install as before….

To install GRUB alone follow the steps:

1. Boot your system with a Ubuntu Bootable Cd and Choose Live CD mode

2. After the Ubuntu boots in the Live-CD mode, press Alt-F2 and type gnome-terminal, and press Enter

3. Now follow the commands below

sudo grub
find /boot/grub/stage1
root (x,y)
setup (x)
quit
sudo shutdown “now” -r

The resulting “find” command will display something like (hd0,1). In this example, you would then type root (hd0,1) and then setup (hd0) in the above area. These numbers might be different; that’s why I included the “find” command. So that find command will locate the partition where linux wass installed previously. That is Ubuntu partitions located either in front or behind their Windows installation or on a completely separate internal/external hard
