Top Forums Shell Programming and Scripting Script extracting ip address from MAC wifi card Post 302923071 by freddie50 on Thursday 30th of October 2014 07:59:30 AM

Well, I think there is a relation:
The ip address associated to the MAC address
is the ip address 2 lines above the MAC address.
But how to extract this with a script?
Maybe should I first change the output of nmap?

Thank you so much for your help,

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 FILES
