SRARPD

Description

srarpd is a simplified implementation of the RARP protocol RFC 903 in C.

Simplified refers to the fact that it only handles requests to lookup IPv4 addresses based on Ethernet (type 0x0001) link layer (MAC) addresses.

srarpd uses sqlite3 3.20.1 (3200100) as the underlying database for the storage/lookup of addresses.

Motivation

Just for the fun of it!

Build dependencies

Linux system with

• ANSI C compiler
• RAW sockets support
• libpthread
• libdl

SQLite3 database schema

Currently there is only one table named ADDRESSES with the following columns:

• MAC_ADDRESS (TEXT) - stores the MAC address in lowercase hexadecimal notation, with the bytes delimeted by :, e.g. a8:33:43:0b:42:1a
• IPV4_ADDRESS (TEXT) - stores the IPv4 address in decimal notation with the bytes delimeted by ., e.g. 192.168.1.3

TODO

• Parse command-line arguments using getopt and validate them
• DB entry listing, insertion, update and deletion
