Learnt a good deal abt DNS and BIND

Staying in home, moving around 3 or 4 rooms makes me really sick.. so thought I could dwell into something I barely know.. how DNS exactly works.. and hows BIND its enhanced version works...

DNS came into picture becas ARPANET failed becas of its HOST.TXT file issue. The issue is there were name collisions which was not handled efficiently.  Traffic and load were not really maintained properly in ARPANET, since it was basically designed for smal netework, when promoted to host internet, things started screwing up. Finally it missed (can we say messed? ) consistency levels...

So, here comes Paul Mockapetris, released RFCs 882 & 883 [ which later developed into RFC 1034 & 1035, with enhancements ]

Hmm.. what exactly is DNS? nothing serious, its a distributed DB :) based on client server technology. Server is referred as Name Server, and client as Resolver..

Domain
|
|
------> Hosts
|
|
------> Sub-domains

First implementation of DNS was JEEVES by Paul as we know.. and the later implementation of DNS is BIND...
So wats BIND?
BIND => Berkley Internet Name Domain, started out in BSD 4.3 by Kevin Dunlap. Now its maintained by Internet Software Consortium

OK..lets get into something thats more interesting.. leaving behind all these history stuff..

How are things organised and working out in DNS?
So its similar to unix file system type of listing..
top-level domian names, followed by second level domain ..

top-level domain names like (.com, .org etc.. ) use the delegation model to traverse through the second level and further down..
So how does managing a domian, subdomain take place.. well its delegated.. the management is like this..

consider a site archu.blogspot.com
.com is the toplevel domian which delegates the google guys to manage blogspot , which is a subdomain, whereas, blogspot guys delegate archu ( its me!! ) to manage that particular page.. its that way as simple as it is.. no collisions..

Sounds fine.. but wat is data is lost in toplevel domain..?
here comes the kool back up strategy they follow... they have a primary master and secondary master to take care of the same..
check out the RFCs for more detailed info reg the same :)

When will Firefox be integrated with KDE?

Since KDE is having its own browser konqueror.. they wont be very happy to integrate firefox..

but users like me who want to have firefox integrated with themes, icons, fonts with that of kde are still in lookout of the solution..

There are lot of links when we google..
there is also a wiki in the topic..
but none of the solution worked here..

And one more to add to my previous post..
Now I am having suse 10.. things are fine hree.. no xserver issues, mp3 issues, no network config probs..
things are really a cake walk here..

Mouse troubling my xserver..

This is the final error that received after i messed up with my xserver in debian sarge..

>> No core pointer device specified
>> unable to determine the screen layout

--

Fatal Server Error:
No screens found

I know there is an issue with my mouse .. i edited in the config file..
tried dpkg-reconfigure xserver-xfree86
not able to judge where there is an issue..
Its with mouse..
only the mouse...
no patience to debug now..
so switching back to python again..

lets see wat happens..

Current Activity - Python Programming..

Dataone was creating some issues in sarge.. din have patience to set it right.. so jus switched over to python code.. whole day was reading advanced bash scripting guide, but since there was no power.. no hands on.. all book and no computer... made me a dull archu.. So now jus reading thru manuals and stuff.. so that I can get my hand into python atleast for 2 more days.. Gave a break to ccna since it was really boring to read it theoritically and its not my cake ..

IBM Certified Administrator for Rational ClearCase UNIX

When searching for some clearcase info.. got hold of this cert..

IBM Certified Administrator for Rational ClearCase UNIX Test 631

I don see any specific books for this exam.. but I think it would be better to have this cert if one's career is based on version controlling using clearcase...!

shc - Generic shell script compiler

shc creates a stripped binary executable version of the script specified with -f on the command line.

The binary version will get a .x extension appended and will usually be a bit larger in size than the original ascii code. Generated C source code is saved in a file with the extension .x.c
