Features of new tube 2009†

• new tube started from 2008.
• This year we will use PXE (network boot of Linux and NFS) for diskless machine.
• We will set up new tube 2009 before our setting new flex.
• new tube machine will setup as follows
• (1) At first, we set up a new tube on the new box.
• (2) We will make a PXE server (Nugraha-san's machine?) and make a new subnet. 192.168.3.0
• (3) The PXE server, we set up tftp, dhcp, and NFS.
• (4) We try to network boot for PXE clients (new tube machine)
• (5) Finally we move to the PXE server to flex and old boxes.

Installation Date†

• We set up a NIC card to Nugraha-san's Linux Machine.
• We make a subnet 192.168.3.0/255.255.255.0
• We set up dhcpd, tftpd, NFS, etc on Nuguraha-san' linux.
• We first set up two boxes on new tube 2009
• The two boxes are connected to 192.168.3.0 subnet
• We try to do network boot on the two boxes.

Computer Specification†

Important factors to set up New Flex†

• Power Supply (PS) of new Flex is little bit different with other PS's i.e. it requires 12x2 and 2 x 2 connector (power) to get power from power supply.
• We have the same PS with different connector which does not start BIOS.
• 2009.4.13, Mahabubu-san and Nugraha-san found this and change PS and succeed to recognize BIOS.
