new blog

Im going to try out adsense for some time now before i actually, maybe , setup my own website. This blog will remain as it is but from now on all new content also iso’s will be available from now on at

http://deadwait.blog.co.in

If anyone feels this is a bad idea please tell me so, already the above blog has so many ads which are not mine, that i dont like the look of it, but then i, have to try this.
NOTE: i myself think now this is a bad idea, if needed ill setup my own website than go on to another blog,
and now im going back to my work on dynamips on live cds,
im working getting the live cd down to 50mb or lesser so wont be updating much till im successful on that.

All right i’ve got my own website up now which is http://www.in2dwok.com

everything will be shifted there from now on , all updates new iso everything.

Just thoughts

I used to be a regular reader of http://www.stevepavlina.com back when i was in muscat and to tell you the truth his website is awesome and can many times be the slap in the face you need to get up and take charge, reading his posts got me the strength to leave the security of my job in Oman and come back to my hometown mumbai and start all over again and its been going great, absolutely great.

But now i really want to branch out on my own, try out new stuff and most of all not work for other people atleast for some part of my life. After getting to where i am today i miss the energy of 2 and a half years back, when i everyday i was literally doing something new, now the job has become routine and i dont know what to do, the only fun i have is when i am working on anything linux, but i cant understand how to learn and use it effectively to upgrade my resume , i just keep work on things which i feel are cool.

Aww forget it, better shut my trap and just march on slowly, but i feel things are headed for a change good or bad , i dont know.

kerrighed cluster

So , its feels like a real long time since im writing anything, i was totally busy for almost the whole last month just trying to install Kerrighed ( http://www.kerrighed.org ) , which is a SSI –> single system image cluster. Now all i wanted was dynamips to run on two or more machine’s, Ok so i know that i can start the hypervisor separately on other machines and use the combined processing power anyways, but my idea was to allow it to be accessible remotely, so i thought i would build a cluster on which dynamips would run and use all the cpu power of the entire cluster.

Now  i have never worked on any clustering software before now new much about it, turns out there are so many different types of clustering software available, the best in terms of popularity, ease, support, documentation  ”seemed” to be openmosix, but as of March 2008 the project is dead, closed by its founder, Moshe Bar. Now reading about openmosix gave me little knowledge about SSI cluster’s, meaning suppose i put up 4 machine’s each with 4 processors and 4 gb ram and i set them up in a SSI cluster, what i get is something looking like one machine with 16 processors and 16gb ram, its true, i was able to do half the size of that cluster ( because that’s how many machines i had in my hand to test ), now there might be many out there who have seen this before, but for me, after a really long time  I saw magic! . When i actually finally managed to get the cluster up and top command showed 8 cpus and 4gb ram, ( cluster of two pc’s quadcore with 2gb ram each) , i just kept staring at it in awe, I swear it was so sexy i left it like that for one and a half day before i actually started testing dynamips on it.

The clustering software i finally ended up using was kerrighed, which  supports one of the newer kernels that is 2.6.20 the next in line would be openssi, which i think supports 2.6.9 or 2.6.12 im not sure right now. installing it took me 3 weeks that too after i gave up installing it on the quadcore machines and tried it on some p3 machines with realtek rtl8139 drivers. the next post will be an entire document on how to install kerrighed on the debian lenny system. The guys on the mailing list of Kerrighed as well as the developers of kerrighed are very helpful and were not irritated at all by my newbie questions, in fact i came out of it knowing a little more about linux, eg: i had never recompiled a kernel before. 

Well did dynamips work? NO! , that hurt, but then it’s ok doing the entire exercise was fun, oh and the reason dynamips did’nt work was kerrighed does’nt support migration of multithreaded processes yet, i did check the migration with a program called cpuburn and it worked fine.  

Well hopefully  i might get some test machine’s again and i could work out something , i also wanted to test cacti on it and see if that’s a feasible option. hmm lets’s see.

dynaflux

ok this is a very light version of slax with only fluxbox as a manager and dynagen and dynamips added, download it here Dynaflux

if you want to use it on your usb , extract the same iso to your USB drive, go to the boot directory and double-click on bootinst.bat , that will make your usb bootable. to extract the iso you can use 7zip.

the size is only 124 mb as of yet and i havent yet added a tftp server and pdfreader.

Just a few pointers,  when your right click on the desktop you get the menu

click on runthisfirst first .

to give a ip address to your ethernet card open terminal and type in ” ifconfig eth0 xx.xx.xx.xx netmask xx.xx.xx.xx gw xx.xx.xx.xx up” without the quotes

the filemanager is like your windows explorer

you will find your windows harddisks in /mnt

So my sis actually paint’s on canvas shoe’s and today i setup a wordpress site for here, so if anyone is interested go ahead to http://shoefu.wordpress.com

By the way, isn’t wordpress just great.?

Lambda Tube

As you know i have just started learning programming ( i mean really learning “programming” ) to the best of my abilities, i was searching for some real world programs made with scheme, coz as i was reading the net you get lot of very smart people telling that learng lisp/scheme will open your mind but then its like generally learn this and then use the techniques or methodology to program in some other language.

Now why would i want to do that?

Anyways i found this program Lambda-tube at http://code.google.com/p/lambda-tube/

a youtube browser which is written in PLTScheme, it actually browses youtube for you and then downloads the songs you choose, when i first downloaded and checked it a week back, it had no proxy support, hence i could not check it at work, i raised a issue on the website and the author Abhishek Mishra reverted back stating that he would add the feature in a few days, today i got the mail that the proxy feature is added, i downloaded it once again and reinstalled on top of the earlier version itself, added the proxy server and port and tried but it didnt work , in the sense i could browse but couldnt download , just restarted the program and it started and i have already downloaded around 20 videos — the only bad point about this program now is that it is too easy hence very addictive , i just couldnt stop browsing and downloading.

Anyways once i complete concrete abstractions by Max Hailperin , i hope to browse through the code of Lambda-tude for better understanding.

Learning Scheme Programming

I am finally taking the plunge and learning programming, i am using the book Concrete Abstractions by Max Hailperin , which is available online here —> http://gustavus.edu/+max/concrete-abstractions.html

I had begun with practical common lisp but then diverted to this book.

The reason i want to learn is that i want to sit down and make my own Network Monitoring System,

nothing groundbreaking , just something i would have total control of but i want to add intelligent troubleshooting integrated into it, i can already do a lot of this using Ruby’s Net/telnet library, but then things just work in it, I dont know how and i need to know , im tired of being so kludgy and just copy pasting scripts from here and there to get my work done.

why am i not learning ruby itself ?

well i did start of from there with some online tutorials but it leaves many questions unanswered to me,

now i am not from a computer science background at all, and it is just the last two years that i have been working as a network engineer so maybe it is that’s why , that i just dont ” get ” things, it’s very frustrating especially when even kids find it so easy nowadays .

Im touching 29 now , does anybody even start learning programming at this age ? oh , why oh why, did i waste my youth ? stupid snooker parlours robbed me of a education . oh fuck it , i did enjoy those years though.

whatever, i hope to learn scheme now and then use only scheme , not try it with ruby or something like that.

i want to learn programming now , not learn it just to make a program i think is useful for me.

lets see what happens, will i give it up like everything i give up before ? i hope not .

ill try and post everyday where i stand.

argus network monitor

Man, i got tired of trying to install nagios or opennms or zenoss or zabbix or hyperic or groundwork i mean like wtf can installs just be simple for poor idiots like me. But then i found argus available at http://argus.tcp4me.com

Im still going through configuring but its such a relief, all i wanted was s simple ping monitoring software and finally i got it. Im sure i’ll be writing more about it in the days to come.

12 days to my marriage

I am to be married in 12 days, dec 29th, i’ll finally marry the love of my life, This last year has been a happy one for me, i don’t remember ever being so happy, preparations are hectic, i have still haven’t finished invitations nor is my suit or y best man’s suit ready, by the way my best man is Glen. 12 days more …..

bgp + mpls (ccip)

So surprise , surprise with all *ucking around on linux  im giving the 642-691 on saturday, lets see what happens, i swear if i pass i complete my ccip by the end of this month and give the ccie R&S next month.

No traffic on my website

A search in Google for cacti xampp ubuntu get’s two pages pointing to either the howtoforge article or the forum, hmmm , how does this search business work ???? i wonder…..
