bptojdb(8) System Manager's Manual bptojdb(8)
NAME
bptojdb - Converts bootptab entries into permanent, static IP entries for JOIN databases.
SYNOPSIS
/usr/sbin/bptojdb [-m | -f] filename
OPTIONS
Create client IDs for Microsoft DHCP clients. Microsoft does not use the client's MAC address by itself as the client identifier.
Instead, it prepends a 01 (Ethernet) to the MAC address and changes the hardware type to 0 (generic). If the clients in your bootptab file
are Microsoft clients, you will need to use the -m option. Create client IDs for FTP Software's DHCP clients. FTP Software does not use
the client's MAC address by itself as the client identifier. Instead, it creates a 16-byte client identifier with the prefix "cid-". If
the clients in your bootptab file are FTP Software DHCP clients, you will need to use the -f option.
DESCRIPTION
The bptojdb program reads entries in a standard bootptab file and creates permanent, static IP entries for the JOIN databases. After read-
ing the bootptab file, bptojdb displays to the standard output entries in a format suitable for the jdbmod utility. Each MAC address in the
bootptab file is given a static IP address with a permanent lease. To store the information in the JOIN databases, run jdbmod with the
converted data. For example: bptojdb bootptab | jdbmod
