>Description:

	When pulling out and re-inserting my network cable (using ex)
	I get this message:

got message of size 144 on Tue Feb 19 20:32:52 2002
RTM_IFINFO: iface status change: len 144, if# 1, flags:<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST>
got message of size 144 on Tue Feb 19 20:32:55 2002
RTM_IFINFO: iface status change: len 144, if# 1, flags:<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST>

	Doing this a couple of times make you quickly lose trace of
	what is happening since the mssage is the same for extraction
	and insertion.

>How-To-Repeat:

	run route monitor

>Fix:

	Print out the carrier status.
