<div><p>Bootstrap Protocol (BOOTP) provides a dynamic method for associating
|
||
workstations with servers and assigning workstation IP addresses and initial
|
||
program load (IPL) sources. </p>
|
||
<p>BOOTP is a TCP/IP protocol used to allow a media-less workstation (client)
|
||
to request a file containing initial code from a server on the network. The
|
||
BOOTP server listens on the well known BOOTP server port 67. When a client
|
||
request is received, the server looks up the IP address defined for the client
|
||
and returns a reply to the client with the client’s IP address and the name
|
||
of the load file. The client then initiates a TFTP request to the server for
|
||
the load file. The mapping between the client hardware address and IP address
|
||
is kept in the BOOTP table on the system.</p>

If you do not have any thin clients attached to your network, you do not need to run the BOOTP server on your system.</li>

<li class="ulchildlink"><strong><a href="rzamvtcpsecbootp.htm">Secure the BOOTP server</a></strong><br />

The BOOTP server does not provide direct access to your iSeries™ system,

and thus represents a limited security exposure.</li>
