Installation

First get the latest stable source of the package from:

Then unpack the package. There are 3 methods to build the package:

  • Debian package
  • Manual installation

Debian package

How to build a debian package:

  • make_deb_pkg.sh
  • dpkg -i <packagename>

The debian package determines if we use inetd or xinetd.

Manual installation

To activate the pxeconfigd daemon utility on other platforms use this procedure:

  • edit '/etc/services', eg:
          pxeconfigd      6611/tcp                       # pxe config daemon
    
  • Install the server, the server can ONLY be started froom inetd or xinetd:
        a) inetd.conf
          - edit '/etc/inetd.conf', eg:
            pxeconfigd stream  tcp nowait  root.sys /usr/sbin/tcpd \
              /usr/local/sbin/pxeconfigd
    
          - /etc/init.d/inetd reload
    
        b) xinetd
          - cp pxeconfigd.xinetd /etc/xinetd.d/pxeconfigd
          - /etc/init.d/xinetd reload
    

Test the setup

You can test it by:

  • telnet localhost pxeconfigd (or port number)
         output:
           Trying 127.0.0.1...
           Connected to localhost.
           Escape character is '^]'.
           ip = 127.0.0.1, hex = 7F000001
           file = /tftpboot/pxelinux.cfg/7F000001
           Connection closed by foreign host.
    

In syslog a line will be added if the removal is succesful:

      Feb 20 09:32:40 test pxeconfigd: /tftpboot/pxelinux.cfg/7F000001

Setup

4) As you can see '/tftpboot/pxelinux.cfg/' is the default directory. If

you placed the config files somewhere else you can add the '-d/--directory' option, eg:

pxeconfigd stream tcp nowait root.sys /usr/sbin/tcpd \

/usr/sara/sbin/pxeconfigd -d /<some>/<other>/<place>

If the daemon works and you want to install/reinstall a node, a link must be placed in the '/tftpboot/pxelinux.cfg' directory. This can be done with the 'pxeconfig' utility. This utility will ask some questions and will make the links for you. The utility requires the following

setup:

1) All the pxe configuration files must start with the keyword 'default.'

N.B.: yes, the dot after 'default' is part and parcel of the keyword! In this distribution two examples are included. Pxeconfig lets the user decide which 'default.' config file to use.

2) If default is a symbolic link to for example default.harddisk, then

default.harddisk is not included in the list where the user can choose from.

3) You can give a command line switch to specify where the

pxe config files reside:

pxeconfig -d /<some>/<other>/<place>

The last utility is 'hexls'. This utility will display the hex pxe config file with the corresponding ip-addresses.

To activate this on a client you must add the following line to the 'master' script of the node. It will remove the pxe config file for the node from the pxe bootserver. I personally place the line just before the umount commands. See below which command to use for which systemimager version. Telnet is not included in the 3.X versions.

# Remove the <hex_ipaddr> file from the pxelinux.cfg directory. # So the client will boot from disk # 3.X) chroot /a telnet $IMAGESERVER 6611 2.X) telnet $IMAGESERVER 6611
