How To - Console Redirection/Headless Workstation
« on: October 29, 2009, 05:33:25 PM »
   1.  This how to guides how to setup a headless workstation

   1. Get the following items

          Null modem cable
          Linux server with agetty installed.


   2. Configure a session in /etc/inittab file with the following options

          S0:235:respawn:/sbin/agetty -L 9600 ttyS0 vt100

          NOTE: Most important note here is use vt100 terminal at 9600 speed for compliance purposes.


   3. Configure your GRUB boot options

          title Red Hat Enterprise Linux AS (2.4.21-50.ELhugemem)
          root (hd0,0)
          kernel /vmlinuz-2.4.21-50.ELhugemem ro root=LABEL=/ console=ttyS0,9600 reboot=warm
          initrd /initrd-2.4.21-50.ELhugemem.img

          NOTE: Most important keyword here is console redirection even during reboot, "console=ttyS0,9600


   4. Setup serial console with agetty in /etc/inittab file

          S0:12345:respawn:/sbin/agetty -L 9600 ttyS0 vt100

   5. Take note that you need to reboot the server for these to take effect especially the console redirection part.
