Serial port console, tested with DRAC6 Express and Ubuntu 14.04

I aint payin for DRAC Enterprise!


create service for console

vim /etc/init/ttyS1.conf

start on stopped rc RUNLEVEL=[12345]
stop on runlevel [!12345]
exec /sbin/getty -L 115200 ttyS1 vt102

sudo start ttyS1

edit grub setting

vim /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="console=ttyS1 console=ttyS1,115200n8"
GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=0 --word=8 --parity=no --stop=1"

sudo update-grub

make sure ttyS1 is present in /etc/securetty (it’s there by default)

we need to assign com2 to DRAC now, either via BIOS or via omconfig (you did install OpenManage, did you?)

omreport chassis biossetup
omconfig chassis biossetup attribute=serialcom setting=com2
omconfig chassis biossetup attribute=crab setting=enabled

or reboot and enter BIOS (F2) Serial Communication section

serial communication....On with serial redirection via com2
serial port address....Serial device1 = com1, serial device2 = com2
external serial connector....Serial device 2
failsafe baud rate....115200
remote terminal type....vt100/vt220
redirection after boot....Enabled
Save the changes and exit.


After reboot ssh to your DRAC and type on prompt

/admin1-> console com2

You’re welcome

  1. […] I used picocom, assuming your port is COM0 (because you might be using COM1 for DRAC console as described here): […]

  2. Thanks for this, only note is that I found
    GRUB_CMDLINE_LINUX_DEFAULT="console=ttyS1 console=ttyS1,115200n8"
    should be
    GRUB_CMDLINE_LINUX_DEFAULT="console=tty1 console=ttyS1,115200n8"
    to allow the os boot to display for ubuntu14.04

    THanks again
