Simple WHOIS Daemon, provides the standard Internet whois directory service It is much simpler to setup and administrator than the other whois daemons available, such as RIPE whois or the original SRC whois. This is because it uses a flat-text file, /etc/swhoisd.conf, instead of a complex database. This whois server is recommended only for small databases (preferably under 100 records and no more than 1000).
