29 years Old...

lessaid — Thu, 15 Jan 2009 04:06:00 +0100

Today I am 29,

I am not going deep on what 29 means exactly, it only mean that 30 is so close.

Another quite year on this blog, so what's happen since my last post ?

I change job twice, BT (the famous big company...) and now CSC.

18 Feb 2008 (my first day @BT), my father had a cva ( cerebral vascular accident), and caused his left side of his body paralysed.

It just change my life, my perspective and vision of things and my projects. Now he can move a little-bit his left foot. Sometime life is hard, very hard. Why him ?

I did pass the CCIE Written, but in August, and will try to pass the lab in January 2010. I run a tiny blog about my CCIE Quest.

Bought a Digital Camera, a Nikon D90, a Wii for my birthday.

Have been to Thailand, and get blocked by the anti-government protesters at Bangkok, so we take a bus to Malaysia and left from kuala lumpur airport ( thanks Emirates for the customer relationship).

Anyway, My wish for this year is to be with my family, be happy.

I hope the next time I will speak about my birthday, I will have a digit

28 years Old

lessaid — Tue, 15 Jan 2008 01:15:00 +0100

Today I am 28,
28 is the second perfect number (after 6 et before 496)[1], a happy number
This calendar year will be the same as 28 years before ( a normal cycle ), I cry the first time a Thuesday, at 13h25.
1 year since my last post, so what's happen?
Well about my work, I just move from telintrans to Orange, and now I am moving to another big company....
I broke up with Albane, 4 month ago; we have been 5 years...
I start my CCIE R&S, the written should be in May '08, lab in December '09
Helped pello to start a French Cisco user’s community group.
Still feeling young in my head, I didn't blog too much, may be because I am lazy sometime, and may be because my last job was more on architecture than on technical stuff.
Well my wish for this year is good health for my family and my friends, learn and learn, get married, some kids and enjoy the life. This year will be the decisive year

my last word is that whatever happens, more I get old, and more I am realize that what my parents says was right... I am getting old .... I am getting old ....

Please create RSA keys to enable SSH.

lessaid — Wed, 28 Feb 2007 16:53:00 +0100

When I try to enable SSH on my router, got the "Please create RSA keys to enable SSH."

So here we are :

rtr-l3(config)#conf t

rtr-l3(config)#aaa new-model
rtr-l3(config)#username admin password 0 a2m1
rtr-l3(config)#ip domain-name ssh
rtr-l3(config)#crypto key generate rsa
The name for the keys will be: rtr-l3.ssh
Choose the size of the key modulus in the range of 360 to 2048 for your
General Purpose Keys. Choosing a key modulus greater than 512 may take
a few minutes.

How many bits in the modulus [512]: 1024
% Generating 1024 bit RSA keys ...[OK]

rtr-l3(config)#crypto key generate rsa general-keys label ssh-key
rtr-l3(config)#ip ssh rsa keypair-name ssh-key

Update :

You can run the command "auto secure ssh"
