Thanks, (on the dhcpd hosts) I 'created' another dhcpd.conf stanza with a
matching (new) lladdr and now dhcp succeeds. arping seems to work but ping
doesn't work and tcpdump -i re0 -envvv shows some bad checksums. netstat -nr
output *doesn'* show link#1 for the dhcp IP address(10.1.2.30).
Here's some further detail:
a8v2:build/packages 36#sh /etc/netstart re0
DHCPREQUEST on re0 to 255.255.255.255 port 67
DHCPACK from 10.1.2.18 (00:02:b3:ca:06:00)
bound to 10.1.2.30 -- renewal in 302400 seconds.
a8v2:build/packages 37#tcpdump -i re0 -envvv
tcpdump: listening on re0, link-type EN10MB
