1 Introduction

Sur des machines (surtout distantes), il est parfois pratique d'obtenir des informations du style, les espace de RAM disponible etc...

Bref, on peut avoir besoin d'autres informations, et je ne sais pas ou mettre tout ce petit monde.

2 Linux

2.1 dmesg

C'est ce qui est écrit lors du boot du kernel et tous les appels kernels (chargements de modules etc...) ça sera écrit ici. Sur certaines distribs, c'est même écrit dans les logs /var/log/*. Ce qui donne un truc du genre :

Command dmesg
dmesg 
[    0.000000] Linux version 2.6.22-14-generic ([email protected]) (gcc version 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)) #1 SMP Tue Feb 12 02:46:46 UTC 2008 (Ubuntu 2.6.22-14.52-generic)

[    0.000000]  BIOS-e820: 0000000000100000 - 000000007fe0ac00 (usable)
...

2.2 dmidecode

Cette commande permet de voir par exemple les espaces de prit au niveau de RAM, les espaces libres et tout autre types d'informations pratiques :

Command dmidecode
# dmidecode 2.9
SMBIOS 2.3 present.
75 structures occupying 2618 bytes.
Table at 0x000F0450.
 
Handle 0xDA00, DMI type 218, 65 bytes
OEM-specific Type
        Header and Data:
                DA 41 00 DA B2 00 17 0B 0E 38 00 00 80 00 80 01
                00 02 80 02 80 01 00 00 A0 00 A0 01 00 58 00 58
                00 01 00 59 00 59 00 01 00 75 01 75 01 01 00 76
                01 76 01 01 00 05 80 05 80 01 00 FF FF 00 00 00
                00
 
Handle 0xDA01, DMI type 218, 35 bytes
OEM-specific Type
        Header and Data:
                DA 23 01 DA B2 00 17 0B 0E 38 00 10 F5 10 F5 00
                00 11 F5 11 F5 00 00 12 F5 12 F5 00 00 FF FF 00
...

2.3 Disques dur

Pour ce qui est des disques dur, utilisez la commande hdparm pour avoir toutes les infos :

Command hdparm
$ hdparm -i /dev/sda
 
/dev/sda:
 
 Model=ST3500320AS                             , FwRev=SD15    , SerialNo=            9QM89WJF

 BuffType=unknown, BuffSize=0kB, MaxMultSect=16, MultSect=?8?
 CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=976773168

 UDMA modes: udma0 udma1 udma2 udma3 udma4 udma5 *udma6 
 AdvancedPM=no WriteCache=enabled
 Drive conforms to: unknown:  ATA/ATAPI-4,5,6,7
 
 * signifies the current active mode

3 BSD

3.1 dmesg

Tout comme linux, il existe la commande dmesg, mais au niveau des logs, c'est pas au même endroit. Il faut regarder dans le fichier /var/run/dmesg.boot :

Command cat
$ cat /var/run/dmesg.boot
OpenBSD 4.2 (GENERIC.MP) #1378: Tue Aug 28 10:48:58 MDT 2007
