    58 To perform one of the above maintenance actions on a testbox copy the
    59 ``do-<action>.cfg`` file over to testbox hex-IP config file name.  Then trigger
    60 a reboot.  The box will then boot the NFS rooted debian image and execute the
    61 maintenance action.  On success, it will remove the testbox hex-IP config file
    62 and reboot again.
    63 
    64 The hex-IP config file name for a testbox is generated by taking the IPv4
    65 address, converting each of the 4 numbers to upper cased hex and remove the
    66 dots.  Given the IP ``10.42.1.96`` you can use the unix ``printf`` command
    67 like this ``printf "%02X%02X02X%02X" 10 42 1 96`` to get the name.
     58To perform one of the above maintenance actions on a testbox, run the
     59``testbox-pxe-conf.sh`` script::
     60
     61    /mnt/testbox-tftp/pxeclient.cfg/testbox-pxe-conf.sh 10.165.98.220 rescue
     62
     63Then trigger a reboot.  The box will then boot the NFS rooted debian image and
     64execute the maintenance action.  On success, it will remove the testbox hex-IP
     65config file and reboot again.

    128 Create ``pxelinux.cfg/do-backup``, ``pxelinux.cfg/do-backup-again``,
    129 ``pxelinux.cfg/do-restore``, ``pxelinux.cfg/do-refresh-info``, and
    130 ``pxelinux.cfg/do-rescue`` configuration files on the form::
    131 
    132   PATH bios
    133   DEFAULT maintenance
    134   LABEL maintenance
    135     MENU LABEL Maintenance (NFS)
    136     KERNEL maintenance-boot/vmlinuz-3.16.0-4-amd64
    137     APPEND initrd=maintenance-boot/initrd.img-3.16.0-4-amd64 testbox-action-backup ro ip=any aufs=tmpfs boot=nfs root=/dev/nfs nfsroot=10.42.1.1:/export/testbox-nfsroot,ro,tcp nfsvers=3 nfsrootdebug
    138   LABEL local-boot
    139   LOCALBOOT
    140 
    141 When you want to preform an action on a testbox, copy the ``do-<action>`` to
    142 ``pxeclient.cfg/<HEX-ip-addr>`` and trigger a boot of the testbox.  The machine
    143 config will be removed automatically once the action has been successfully
    144 completed.
    145 
    146 Note! We use ``ip=any`` and not ``ip=dhcp`` as the former seems to work more
    147       reliably in our lab.
     126Copy the ``testbox-pxe-conf.sh`` script file found in the same directory as
     127this document to ``/mnt/testbox-tftp/pxelinux.cfg/``.  Edit the copy to correct
     128the IP addresses near the top, as well as any linux, TFTP and PXE details near
     129the bottom of the file.   This script will generate the PXE configuration file
     130when performing maintenance on a testbox.

     223 - Edit ``/etc/ssh/sshd_config`` setting ``PermitRootLogin`` to ``yes`` so we can ssh
     224   in as root later on.

     241       We use NFS version 3 as that works better for our NFS server and client,
     242       remove if not necessary.  The ``noauto`` option is to work around mount
     243       trouble during early bootup on some of our boxes.
