In da Wok ……

Now im a brand new fan of Electric Six, just love every number of theirs, but watching Rajesh Khanna and Mumtaz shake to this song is a pure wtf??? trip.

enjoy

this is just two cool, go to the link here, wait for one and half minute and then it starts.

ldp in openbsd –> http://www.openbsd.org/cgi-bin/man.cgi?query=ldpd&apropos=0&sektion=0&manpath=OpenBSD+Current&arch=i386&format=html

openbsd 4.6 does not detect the stupid attansic network card on my acer aspire one d250, i might be trying this on a xen machine in a day or two.

Linux already has this functionality, but no proper docs anywhere unless your a all-in-one expert, mikrotik has pulled of mpls-vpn with vrf functionality, and im sure i read somewhere that they pulled the mpls code from the vyatta code base.

I had read this paper http://2008.asiabsdcon.org/papers/P8A-paper.pdf which mentioned vrf instances in openbsd. this guy here –> http://www.spacebugs.nl/index.php?option=com_content&task=view&id=259&Itemid=33 , has already tested it, sort of like a vrf-lite. his site also has info on how to install openbsd on a soekris board, now what remains is mpls-vpns and l2tpv3 pseudowires.

When you have to determine why things went wrong you need to know how they work.

linux helps you do thats

linux helps you use the knowledge you gain by tinkering with it in realtime

my linux laptop can become a router

my linux laptop can become a firewall

my linux laptop can become a ids/ips

my linux laptop can become a access-point

my linux laptop can become a pbx

my linux laptop can do all of the above at the same time

i have done all of the above

iptables is awesome , even when you have not understood it

through linux i realised that learning to script/program ( even just a little bit ) can help you tremondously in your job as a network engineer.

my job is fun again because of linux

linux teaches you patience

it strips away any sense of pride and leaves you a quiet and humble person

linux gives you peace

this post is to remind me why i keep using linux, on the days when i just want to rip apart my laptop and then puke on it

slitaz is awesome.

got the BIRD internet routing daemon, bird, compiled and will package it today and set it up in the repos for slitaz. as far as i know it will be the only routing daemon packaged for slitaz. The reason i got interested in BIRD is that right now among the other daemons in the linux world, this one seems to be the latest in updates. i guess working on it and later making a live cd for the same will benefit BIRD as more people can then get on to it. Im still waiting for the day when i can get a open source, without hassles, mpls/bgp vpn up on linux.

well, somebody has made a very limited implementation of bgp in the ruby programming language, and it available here http://github.com/mc/rubybgp . it would be fun to read and learn again BGP from totally different point of view, i know a little bit of ruby, just enough to make small network monitoring scripts along with bash. so i guess i can start learning a little bit more by reading and trying to make sense of the rubybgp code, there is also another project here http://rubyforge.org/projects/bgp4r/ which i intend to pick apart too.

Oh how i wish i had more time.

slitax linux busybox already has vconfig in it, which if you did’nt know ( i did’nt till an hour back), lets you setup vlan interfaces in your linux box, like sub-interfaces in your cisco router. so you too can make your slitaz laptop a router on a stick very easily with this. the command goes like this, as root type

vconfig add eth0 47

the above command adds a interface eth0.47 which will have encapsulation of 802.1q, if you get any errors when you give the command, most probably it will be that the vlan module has not been loaded, on slitaz we load it like this

modprobe 8021q

then you try again and you should not get any errors, after that all you have to do is

ifconfig eth0.47 up

and confirm that the interface is up with the ifconfig command.

there you have it, slitaz linux router on a stick.

notes: for linux to act as a router , you have type in the following command

echo 1 > /proc/sys/net/ipv4/ip_forward

also i add 8021q to the modules section in /etc/rcS.conf

A nice article on vlans in linux is available here, http://www.linuxjournal.com/article/7268

well not a full blown router yet, but good enough for static routes. So its quite simple to get your slitaz box to act as a router, just install iptables, with the command

tazpkg get-install iptables

and once that is installed just type in the foll. command as root

echo 1 > /proc/sys/net/ipv4/ip_forward

and there you have it, you slitaz box is all ready to forward ip packets (tell you the truth, im not sure if you even need iptables for routing, i still need to learn this stuff on linux).

anyways next work on slitaz is to start a pppoe access authentication server and then hook it up with freeradius, later i’ll start work with quagga, though  i have already compiled it before, i never got to work with it, neither have i packaged it, so hopefully by the end of the month ill finish these three.
