Setting up a BOOTP gateway

A BOOTP client normally finds a BOOTP server by broadcasting on the subnet that is connected to its network interface. If you want a BOOTP client to obtain its configuration information from a BOOTP server that is not on the same subnet, you must configure a BOOTP gateway on the same subnet as the client. The BOOTP gateway listens for broadcast BOOTP requests, and forwards them to a BOOTP server.

To configure a BOOTP gateway:

1. Log in as root.

2. The bootpgw daemon is started by the Internet services daemon, inetd, when required. To enable a BOOTP gateway, add the following line in /etc/inetd.conf:

   bootps dgram/i udp wait root /usr/sbin/in.bootpgw in.bootpgw server
   

   Replace server with the name or IP address of the BOOTP server, or that of another BOOTP gateway in the path to the server.

3. Force inetd to re-read /etc/inetd.conf by sending it a SIGHUP signal:
   
   kill -HUP `cat /etc/saf/inetd/_pid`

   or by stopping and restarting it:
   
   sacadm -k -p inetd
   sacadm -s -p inetd

   inetd will now be able to start bootpgw when the gateway receives a BOOTP request broadcast from a client.
