Me accessing my DataOne broad band wireless in my hardy(ubuntu 8.04). For the post two year Iam using Dataone.. But I was not sure whether the wireless port in my modem was Input port or Output port. I tried connecting my Lap after purching my Lap.  I didnt know exactly what mode to use in my admin setup page for accessing… I was randomly trying one after the other.. And got it at last.

My Interface Setup in my admin page is in PPoA/PPoE mode, with the username and pasword defined in the router setup page itself. And my Cute hardy scans for the Wireless Lan and connects automatically leaving me no work now a days. My Hardy is always cute, When my boot process is over Iam ready to surf my Net, provided my Dataone modem is ON.

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

The command used to find the $cat /proc/version

Eg..

$ cat /proc/version
Linux version 2.6.24-16-generic (buildd@palmer) (gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)) #1 SMP Thu Apr 10 13:23:42 UTC 2008

Similarly for knowing the CPU information use the command

$cat /proc/cpuinfo

If you are using a Core 2 duo processor informations of both the processors will be listed separatly. Check it out…..

Similarly /proc/ directory has many files use cat command to many information line meory info, swap space informations, etc using appropriate files.

Yes the answer is Dynamic DNS. Dynamic DNS is nothing but a service, (probably free service many a times) provided my many domain holders. (Eg. www.dyndns.com, www.no-ip.net…).

Dynamic DNS is one of the services provided by them for free. Also the provide few more services in which few are free and few are of cost. Like email forwarding, url forwarding etc.

Dynamic DNS is nothing but a service, that lets you register your Dynamic IP to a url in the form http://user.provider-domain.com… They give many choices of theses domain names…. You will have to change the IP address as and when it changes. You can register with those providers and create mapping between you dynamic Ip and urls. You can edit the IP any time you wish, as the ip wont be constant. You can also mention the time limit for which the IP will exist.

I wanted to allow all those who use internet to access the webpage hosted in my local webserver, when i am in a adsl dhcp broadband line. That is, by giving the IP address that is temporarily assigned to me, the user in the other end in internet should access my webpage . I wanted to know whether this works atleast for the few mins the IP address assigned to me.

I made a try, using ifconfig i found the system IP address. It said 192.168.1.33. And for editting the router setting, I used 192.168.1.1. so i found these Ip addresses are dummy, used just to establish a lan between the system and the router or modem.

Using www.whatsmyipaddress.com i found the real temporary dhcp ip assigned to me in the internet was something else. like ww.xxx.yy.zz. I gave the Ip address to my friend who was online and enabled my webserver service and i expected that my friend should get the page that was hosted with in my webserver. But my expectation went wrong. He got my router settings page requesting for username and password. I confirmed that it was my router settings page that i eddited sitting in my home. . .

Somebody could edit my router settings knowing my dhcp ip and my username and password. The same came when i gave the ww.xxx.yy.zz ip address in a browser of mine…. Still trying whether i could farward the request from my router to my system. Whether it is possible????

If some body could help comment me. . . .

May be my assemtion may be wrong in between correct me if i was wrong…..

During this try i Came across the word Dynamic DNS. Will tell you in details in my next post.
