Endel Intel systemer idag kommer med vPro. Dette vil si at det er en slags billig iLO\/iDRAC l\u00f8sning integrert. Systemet jeg konfigurerte hadde en eldre versjon, som kun gir mulighet for \u00e5 styre power samt konsoll over seriell. For oss er det mer enn godt nok for breakfix ved feil.<\/p>\n
I korte trekk hva som m\u00e5 konfigureres.<\/p>\n
1. IP p\u00e5 Intel ME firmware. Trykk F9? rett etter BIOS. I utgangspunktet kan Intel ME ligge p\u00e5 samme IP som host, og ta over trafikk p\u00e5 vei inn p\u00e5 maskinen. Av gammel vane liker jeg helst \u00e5 separere denne trafikken helt.

\n2. Konfigurer grub
\n
\n# If you change this file, run 'update-grub' afterwards to update
\n# \/boot\/grub\/grub.cfg.
\n# For full documentation of the options in this file, see:
\n# info -f grub -n 'Simple configuration'<\/p>\n
\nGRUB_TIMEOUT=5
\nGRUB_DISTRIBUTOR=`lsb_release -i -s 2> \/dev\/null || echo Debian`
\nGRUB_CMDLINE_LINUX_DEFAULT=\"quiet elevator=deadline console=ttyS2,115200n8\"
\nGRUB_CMDLINE_LINUX=\"\"<\/p>\n
\n# This works with Linux (no patch required) and with any kernel that obtains
\n# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
\n#GRUB_BADRAM=\"0x01234567,0xfefefefe,0x89abcdef,0xefefefef\"<\/p>\n
\nGRUB_TERMINAL=\"console serial\"
\nGRUB_SERIAL_COMMAND=\"serial --port=0xc000 --speed=115200 --word=8 --parity=no --stop=1\"<\/p>\n
\n# note that you can use only modes which your graphic card supports via VBE
\n# you can see them in real GRUB with the command `vbeinfo'
\n#GRUB_GFXMODE=640x480<\/p>\n
\n#GRUB_DISABLE_LINUX_UUID=true<\/p>\n
\n#GRUB_DISABLE_RECOVERY=\"true\"<\/p>\n
\n#GRUB_INIT_TUNE=\"480 440 1\"
\n<\/code>
\nKort forklaring p\u00e5 “–port=0xc000”. Denne finner du ved \u00e5 kj\u00f8re:
\n
\n# dmesg |grep ttyS2 |grep irq
\n[ 0.527818] 0000:00:03.3: ttyS2 at I\/O 0xc000 (irq = 17, base_baud = 115200) is a 16550A
\n<\/code>
\nSer at det stemmer med
\n
\n# lspci |grep KT
\n00:03.3 Serial controller: Intel Corporation 82Q35 Express Serial KT Controller (rev 02)
\n<\/code>
\n3. Konfigurer systemd med getty.
\n
\n# systemctl enable serial-getty@ttyS2.service
\n# systemctl start serial-getty@ttyS2.service
\n<\/code>
\n4. Koble til med amttool \/ amtterm
\n
\n# export AMT_PASSWORD=passw0rd
\n# amttool hostname
\n### AMT info on machine 'hostname' ###
\nAMT version: 3.2.3
\nUse of uninitialized value $domainname in printf at \/bin\/amttool line 244.
\nHostname: hostname.
\nPowerstate: S0
\nRemote Control Capabilities:

\n OemDefinedCapabilities IDER SOL BiosSetup
\n SpecialCommandsSupported PXE-boot HD-boot cd-boot
\n SystemCapabilitiesSupported powercycle powerdown powerup reset
\n SystemFirmwareCapabilities 0
\n# amtterm hostname
\namtterm: NONE -> CONNECT (connection to host)
\nipv4 hostname [192.168.2.3] 16994 open
\namtterm: CONNECT -> INIT (redirection initialization)
\namtterm: INIT -> AUTH (session authentication)
\namtterm: AUTH -> INIT_SOL (serial-over-lan initialization)
\namtterm: INIT_SOL -> RUN_SOL (serial-over-lan active)
\nserial-over-lan redirection ok
