Hi!

I'm hoping that this is the right place to post this. If not, pleas
tell me where i shud post it.

I think ther is some form of racecondition in the dhcpcd. I cant get
an address when im at my scool, it takes like 3-4 tryes to get one.
They have checked ther servers and dont think its a config miss. Im
running arch linux, so i think the dhcpcd version is dhcpcd 5.0.6-1.
Below is the output from dhcpcd:

bash-3.2# dhcpcd wlan0
dhcpcd: version 5.0.4 starting
dhcpcd: wlan0: broadcasting for a lease

dhcpcd: wlan0: checking for 194.47.156.241
dhcpcd: wlan0: NAK: requested address not available from 194.47.157.1

it continues like this untill reciving a timeout or sucessing with
getting a lease. Dose anybody have any ide whats wrong hear? I will
try to get some tcpdumps for further investigation.
