>Release:        FreeBSD 3.4-STABLE i386
>Organization:
Alcatel Australia Limited
>Environment:

	Recent 3.4-STABLE

>Description:

	When routed(8) receives a RIP message from a non-standard port,
	it syslogs a message like "discard RIP response from unknown port
	51982".  Unfortunately, the port number is byte-swapped.  Also,
	the lack of source host information makes locating the offending
	host more difficult.

>How-To-Repeat:

	Run routed.  Generate RIP response messages to the host with a
	source port other than 520.

>Fix:

	The following correctly byte-swaps the source port before printing
	it and also reports the source IP address.
