<h2>Dynamic Host Configuration Protocol Server Exit Programs</h2>
|
||
|
|
|
||
|
|
<p>The iSeries<SUP>(TM)</SUP> Dynamic Host Configuration Protocol (DHCP) server assigns and
|
||
|
|
releases TCP/IP addresses from client hosts in a network. Exit points have been
|
||
|
|
provided so that user-written programs can be called from the running DHCP
|
||
|
|
server. They allow for customer-supplied security validation of incoming client
|
||
|
|
requests, as well as notification when IP addresses are assigned or
|
||
|
|
released.</p>
|
||
|
|
|
||
|
|
<p>The DHCP Request Packet Validation exit program allows for incoming client
|
||
|
|
request packets to be screened by a user program that starts any processing on
|
||
|
|
it. The user program is able to communicate back to the DHCP server that either
|
||
|
|
the packet should be discarded or that it should be allowed to process.</p>
|
||
|
|
|
||
|
|
<p>The Address Binding Notification exit program and the Address Release
|
||
|
|
Notification exit program are for notification purposes only. These allow for
|
||
|
|
user applications to keep track of which IP addresses are currently in use and
|
||
|
|
by which clients.</p>
|
||
|
|
|
