Hi,
I may have a misbehaving DHCP server :
--
$ cat /var/log/daemon.log.1 /var/log/daemon.log 2>/dev/null | grep
dhclient | cut -d':' -f4- | uniq -c
18225 DHCPREQUEST on eth0 to 82.224.x.y port 67
1 DHCPREQUEST on eth0 to 255.255.255.255 port 67
1 DHCPACK from 82.224.x.y
1 bound to 82.224.z.p -- renewal in 249667 seconds.
15075 DHCPREQUEST on eth0 to 82.224.x.y port 67
# dhcping -v -s 255.255.255.255
Got answer from: 82.224.x.y
received from 82.224.x.y, expected from 255.255.255.255
no answer
# dhcping -v -s 82.224.x.y
no answer

My ISP's DHCP server gives a 3-day lease. When this leases expires, dhclient
sends a DHCP request to the known server but the server seems to only answer
on broadcast 255.255.255.255. As a result, my logs ar filling with DHCPREQUESTs
for three days every 6 days.
dhclient should handle this case (request on broadcast after a number of
unanswered requests).
Feel free to ask for more info.
