Hi,
I didn't see this behaviour with netstat in FreeBSD and OpenBSD.
Does this mean that netstat in NetBSD is just different??
netstat -an still shows the port:
vua-y->/root> netstat -an
Active Internet connections (including servers)
Proto Recv-Q Send-Q Local Address Foreign Address
State
tcp 0 0 192.168.1.8.22 192.168.1.13.1210
ESTABLISHED
tcp 0 0 *.22 *.*
LISTEN
udp 0 0 *.61050 *.* <====
udp 0 0 *.514 *.*
Active UNIX domain sockets
[snip]
Thanks,
Hoang
