new blog

Posted in general on July 25, 2008 by deadwait

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

Posted in general on July 25, 2008 by deadwait

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

Posted in general with tags , , , on July 21, 2008 by deadwait

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

Posted in general with tags , , on July 2, 2008 by deadwait

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

GNS3 on live cd

Posted in Cisco, Linux with tags , on June 21, 2008 by deadwait

IMPORTANT : the downloads are also available on http://www.gns3-labs.com  for a stable connection you can download the ISO and tar from there itself.  thanx a ton, lenny.

USB users having a problem with dynamips crashing — > change the working directory to somewhere on your USB , most probably your usb will be like this /mnt/sdb1 and so you can specify the working directory in your .net file like this  workingdir = /mnt/sdb1  .  thanx suhail and rajan for pointing out the issue.

Also would anyone like a live cd based on puppylinux, i think the entire cd should come around 140 mb with gns3 and 110 mb with only dynamips and dynagen.

 

OK, i finally got the gns3 slax live cd uploaded on 4shared, i have had to split the files in three , the total download comes to around 250 mb approx. you will need to use a program like 7-zip to extract the iso as well as the usb versions. to download the same headover to the newly createad downloads page on the right.
