| [9] | 1 | Here follow some basic installation instructions. |
|---|
| [5] | 2 | |
|---|
| [41] | 3 | If you are using DEBIAN then you can run the following utility: |
|---|
| 4 | make_deb_pkg.sh) This will make debian package that you can install |
|---|
| 5 | with dpkg -i <packagename> |
|---|
| 6 | |
|---|
| 7 | |
|---|
| 8 | To activate the 'pxeconfigd' daemon utility on other platforms use this |
|---|
| 9 | procedure: |
|---|
| [5] | 10 | 1) edit '/etc/services', eg: |
|---|
| [41] | 11 | pxeconfigd 6611/tcp # pxe config daemon |
|---|
| [5] | 12 | |
|---|
| 13 | 2) edit '/etc/inetd.conf', eg |
|---|
| 14 | pxeconfigd stream tcp nowait root.sys /usr/sbin/tcpd \ |
|---|
| 15 | /usr/sara/sbin/pxeconfigd |
|---|
| 16 | |
|---|
| 17 | NOTE: the pxeconfigd can only be started from inetd!!! |
|---|
| 18 | |
|---|
| 19 | 3) kill -1 `pidof inetd` (Linux) |
|---|
| 20 | |
|---|
| 21 | 4) You can test it by: |
|---|
| [7] | 22 | telnet localhost pxeconfigd (or port number) |
|---|
| [5] | 23 | |
|---|
| 24 | output: |
|---|
| 25 | Trying 127.0.0.1... |
|---|
| 26 | Connected to localhost. |
|---|
| 27 | Escape character is '^]'. |
|---|
| 28 | ip = 127.0.0.1, hex = 7F000001 |
|---|
| 29 | file = /tftpboot/pxelinux.cfg/7F000001 |
|---|
| 30 | Connection closed by foreign host. |
|---|
| 31 | |
|---|
| [6] | 32 | In syslog a line will be added if the removal is succesful: |
|---|
| 33 | Feb 20 09:32:40 test pxeconfigd: /tftpboot/pxelinux.cfg/7F000001 |
|---|
| [5] | 34 | |
|---|
| 35 | 4) As you can see '/tftpboot/pxelinux.cfg/' is the default directory. If |
|---|
| [9] | 36 | you placed the config files somewhere else you can add the |
|---|
| [5] | 37 | '-d/--directory' option, eg: |
|---|
| 38 | pxeconfigd stream tcp nowait root.sys /usr/sbin/tcpd \ |
|---|
| 39 | /usr/sara/sbin/pxeconfigd -d /<some>/<other>/<place> |
|---|
| 40 | |
|---|
| [9] | 41 | If the daemon works and you want to install/reinstall a node, a link |
|---|
| [5] | 42 | must be placed in the '/tftpboot/pxelinux.cfg' directory. This can |
|---|
| 43 | be done with the 'pxeconfig' utility. This utility will ask some |
|---|
| [9] | 44 | questions and will make the links for you. The utility requires the following |
|---|
| [5] | 45 | setup: |
|---|
| [9] | 46 | 1) All the pxe configuration files must start with the keyword 'default.' |
|---|
| 47 | N.B.: yes, the dot after 'default' is part and parcel of the keyword! |
|---|
| [5] | 48 | In this distribution two examples are included. Pxeconfig lets the |
|---|
| [9] | 49 | user decide which 'default.' config file to use. |
|---|
| [5] | 50 | |
|---|
| [9] | 51 | 2) If default is a symbolic link to for example default.harddisk, then |
|---|
| [5] | 52 | default.harddisk is not included in the list where the user can |
|---|
| 53 | choose from. |
|---|
| 54 | |
|---|
| [9] | 55 | 3) You can give a command line switch to specify where the |
|---|
| [5] | 56 | pxe config files reside: |
|---|
| 57 | pxeconfig -d /<some>/<other>/<place> |
|---|
| 58 | |
|---|
| [6] | 59 | The last utility is 'hexls'. This utility will display the hex pxe config |
|---|
| [9] | 60 | file with the corresponding ip-addresses. |
|---|
| [5] | 61 | |
|---|
| [9] | 62 | To activate this on a client you must add the following line to the 'master' |
|---|
| [6] | 63 | script of the node. It will remove the pxe config file for the node |
|---|
| [30] | 64 | from the pxe bootserver. I personally place the line just before the umount |
|---|
| 65 | commands. See below which command to use for which systemimager version. |
|---|
| 66 | Telnet is not included in the 3.X versions. |
|---|
| [6] | 67 | # Remove the <hex_ipaddr> file from the pxelinux.cfg directory. |
|---|
| 68 | # So the client will boot from disk |
|---|
| 69 | # |
|---|
| [41] | 70 | 3.X) chroot /a telnet $IMAGESERVER 6611 |
|---|
| 71 | 2.X) telnet $IMAGESERVER 6611 |
