Rappel :
i386 : architecture x86 32 bits (386)
i586 : architecture x86 32 bits ( Pentium, Pentium MMX ou compatible AMD Duron )
i686 : architecture x86 32 bits ( Pentium 2, 3 et 4 ou compatible AMD )
x86_64 : architecture x86 64 bits ( AMD 64, Intel Core Duo )
Does amd64 only for AMD 64-bit CPUs?
A: No. "AMD64" is the name chosen by AMD for their 64-bit extension to the Intel x86 instruction set. Before release, it was called "x86-64" or "x86_64", and some distributions still use these names. Intel refers to its AMD64 implementation as "Intel64" previously named "EM64T". The architecture is AMD64-compatible and Debian AMD64 will run on AMD and Intel processors with 64-bit support. Because of the technology paternity, Debian uses the name "AMD64".

| Quelle est ma distrib ? |  |
Note : lsb = linux standard base
Quelle version ?
Exemple :
$ cat /etc/debian_version
wheezy/sid |
$ uname -a
Linux monsysteme 3.1.0-1-amd64 #1 SMP Tue Jan 10 05:01:58 UTC 2012 x86_64 GNU/Linux |
Note : sid = Unstable

| Quel noyau |  |
$ uname -a
Linux cri-brri 2.6.32-44-generic #98-Ubuntu SMP Mon Sep 24 17:32:45 UTC 2012 i686 GNU/Linux
$ cat /proc/version
Linux version 2.6.32-44-generic (buildd@akateko) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5.1) ) #98-Ubuntu SMP Mon Sep 24 17:32:45 UTC 2012 |
| Quel processeur ? |  |
cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 15
model name : Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz
| Combien de processeurs ? |  |
Pour connaitre le nombre de processurs physiques d'un serveur, tapez la commande suivante:
$ cat /proc/cpuinfo | grep "physical id"
physical id : 0
physical id : 1
physical id : 0
physical id : 1 |
=> 2 processeurs (0 et 1)

| Mon système est il chargé ? |  |
La commande procinfo permet d'afficher la charge du système (globale et
par utilisateur), la charge réseau, l'occupation mémoire, etc...
Utilisation :
apt-get install procinfo
procinfo
