Revision:	1.17
Committed:	Tue Feb 27 19:14:26 2001 UTC (23 years, 9 months ago) by pjm2
Content type:	text/plain
Branch:	MAIN
Changes since 1.16:	+10 -2 lines
Log Message:	Updated to comply with the new FilterManger configuration protocol. Namely, the ihost now also sends "FQDN" to the server to request its fully qualified domain name. This simplifies the task of writing hosts as it no longer means that the host has to work out its own machine name (which is sometimes a non-trivial task on certain platforms)
