I have 2 programs who try to listen UDP broascasts, both fails.
The first is rwhod (I use it to monitor a lot of computers):
# lsof | grep rwho | grep UDP
in.rwhod 891 root 3u IPv4 0x30002675e60 0t0 UDP *:who (Idle)
# snoop broadcast and udp
... displays what I think ...
# truss -p 891
recvfrom(3, 0xFFBFF7F4, 1068, 0, 0xFFBFF7E4, 0xFFBFFC20) (sleeping...)
So rwhod opens a socket, waits for packets, nothing arrives in rwhod
but snoop show packets. ifconfig shows a good broadcast address.
My second problem is ntpd: my configuration was to listen UDP
broadcast from a NTP server. It also fails...
Did I make a mistake? Is there any kind of firewall on default
Solaris 9 installations?
