In this first of may, OpenBSD is out with the version 5.5. Some news that you can read by yourself here : http://www.openbsd.org/55.html Have good downloads and upgrade ;)
I have taken care of it to make some patches against nsh to compile against 5.5 :
Dear readers,
It is not usual to have a cook blog post here. I am not aware of cooking things, but to please my daughter I test this one and it was a success.
Here it is a HOWTO to make pancakes. I am a newbie in cooking, so it is easy.
Recipe for 6-8 pancakes Preparation time : 10 minutes Cooking time : 20 minutes Total time of the recipe : 30 minutes
Sorry for english readers, it will be a french article today.
Cet article n’est juste que ma réflexion et n’engage que moi. Ceci n’est peut-être pas votre vision. Si mes arguments ne sont pas fondés, je suis ouvert à la discussion.
Dans le feuilleton du mois de Mars qu’est le rachat de SFR, où les protagonistes sont Bouygues Telecom et Altice/Numericable, l’état en la représentation par M. MONTEBOURG se positionne et participe au choix économique. Je trouve que l’état va au devant d’une catastrophe ou de catastrophes.
This a question which I ask for a long time : is this e Cisco CEF equivalent on Redback router ?
A friend gives me the answer :

I have already make tiny lab with xconnect, but my curiosity has been recently exacerbated so that I can see exactly how it works…
What occurs behind the scene when you press ENTER (the reflexive command has already been pushed on R4) ?
R6(config-if)# xconnect 4.4.4.4 1111 encapsulation mpls
You can see on R4 :
R4#debug mpls ldp targeted-neighbors
LDP Directed Adjacency changes debugging is on
R4#debug mpls ldp transport connections
LDP transport connection events debugging is on
R4#debug mpls ldp transport events

Just to welcome my little son : Clément who was born on 15th april 2013.
I think CCIE studies will be delayed for some time, but my desire is already there… Proof : some 2611, 3550, 1841 are here : ready to study at home ;) So I will be back to game really nearly.
For the first time of life I have seen Sting in concert and it was in rouen : my city. It was great ! It was really great ! Thank you Sting for this awful moment ! This concert will remain etched in my memory. Ok I’m a fan!
THANK YOU !
I was reading all my RSS feeds and I am subscribed to http://mellowd.co.uk/ccie/ . I have noticed this post for you : http://mellowd.co.uk/ccie/?p=2923 It talks about RD, RT and label about MPLS. I found this post really clear about this terms and concepts.
To sum-up :
I recommand to use IP in IP_ASN. I understand it is really easy to read : 3215:100 and not 81.252.160.88:100. The last one is less easy, but when you deploy a large MPLS cloud and you must supply some load-balancing or fail-over on different PE, the RR(Route Reflector) will choice the best route in the two : 3215:100:192.168.1.0 which is received). With IP1:100:192.168.1.0 and IP2:100:192.168.1.0 the two routes will be used, so you will be able to load balance trafic over two links.
For those of you which need to access by means of “Remote Desktop” you can use :
And you can use both LogmeIn Hamachi and VNC. Hamachi is a software which can make network betweeen devices. Against logmein product which lot of you know, here it is at Level2 (OSI).
How you create your VPN ?
For Linux users, you must install vnc4server and hamachi (supplied by LogmeIn) package (dpkg is your friend). Then you launch your vnc server :
For those of you, which need to reset password on PIX515, you will not find somthing like other cisco devices (button to push, BREAK+conf-reg). You must hit ESC when it is asked to you, then :
