1 | Here follow some basic installation instructions. See for |

---|
5 | If you are using DEBIAN then you can run the following utility: |
---|
6 | - debian/rules binary |
---|
7 | - dpkg -i <packagename> |
---|
8 | |
---|
9 | Else: |
---|
10 | - ./configure |
---|
11 | - To activate the 'pxeconfigd' daemon utility on other platforms use this |
---|
12 | procedure: |
---|
13 | 1) edit '/etc/services', eg: |
---|
14 | pxeconfigd 6611/tcp # pxe config daemon |
---|
15 | |
---|
16 | 2) Install the server: |
---|
17 | a) inetd.conf |
---|
18 | - edit '/etc/inetd.conf', eg: |
---|
19 | pxeconfigd stream tcp nowait root.sys /usr/sbin/tcpd \ |
---|
20 | /usr/sara/sbin/pxeconfigd |
---|
21 | |
---|
22 | - /etc/init.d/inetd reload |
---|
23 | |
---|
24 | b) xinetd |
---|
25 | - cp pxeconfigd.xinetd /etc/xinetd.d/pxeconfigd |
---|
26 | - /etc/init.d/xinetd reload |
---|
27 | |
---|
28 | NOTE: the pxeconfigd can only be started from inetd or xinetd!!! |
---|
29 | |
---|
30 | |
---|
31 | 4) You can test it by: |
---|
32 | telnet localhost pxeconfigd (or port number) |
---|
33 | |
---|
34 | output: |
---|
35 | Trying 127.0.0.1... |
---|
36 | Connected to localhost. |
---|
37 | Escape character is '^]'. |
---|
38 | ip = 127.0.0.1, hex = 7F000001 |
---|
39 | file = /tftpboot/pxelinux.cfg/7F000001 |
---|
40 | Connection closed by foreign host. |
---|
41 | |
---|
42 | In syslog a line will be added if the removal is succesful: |
---|
43 | Feb 20 09:32:40 test pxeconfigd: /tftpboot/pxelinux.cfg/7F000001 |
---|
44 | |
---|
45 | 4) As you can see '/tftpboot/pxelinux.cfg/' is the default directory. If |
---|
46 | you placed the config files somewhere else you can add the |
---|
47 | '-d/--directory' option, eg: |
---|
48 | pxeconfigd stream tcp nowait root.sys /usr/sbin/tcpd \ |
---|
49 | /usr/sara/sbin/pxeconfigd -d /<some>/<other>/<place> |
---|
50 | |
---|
51 | If the daemon works and you want to install/reinstall a node, a link |
---|
52 | must be placed in the '/tftpboot/pxelinux.cfg' directory. This can |
---|
53 | be done with the 'pxeconfig' utility. This utility will ask some |
---|
54 | questions and will make the links for you. The utility requires the following |
---|
55 | setup: |
---|
56 | 1) All the pxe configuration files must start with the keyword 'default.' |
---|
57 | N.B.: yes, the dot after 'default' is part and parcel of the keyword! |
---|
58 | In this distribution two examples are included. Pxeconfig lets the |
---|
59 | user decide which 'default.' config file to use. |
---|
60 | |
---|
61 | 2) If default is a symbolic link to for example default.harddisk, then |
---|
62 | default.harddisk is not included in the list where the user can |
---|
63 | choose from. |
---|
64 | |
---|
65 | 3) You can give a command line switch to specify where the |
---|
66 | pxe config files reside: |
---|
67 | pxeconfig -d /<some>/<other>/<place> |
---|
68 | |
---|
69 | The last utility is 'hexls'. This utility will display the hex pxe config |
---|
70 | file with the corresponding ip-addresses. |
---|
71 | |
---|
72 | To activate this on a client you must add the following line to the 'master' |
---|
73 | script of the node. It will remove the pxe config file for the node |
---|
74 | from the pxe bootserver. I personally place the line just before the umount |
---|
75 | commands. See below which command to use for which systemimager version. |
---|
76 | Telnet is not included in the 3.X versions. |
---|
77 | # Remove the <hex_ipaddr> file from the pxelinux.cfg directory. |
---|
78 | # So the client will boot from disk |
---|
79 | # |
---|
80 | 3.X) chroot /a telnet $IMAGESERVER 6611 |
---|
81 | 2.X) telnet $IMAGESERVER 6611 |
