dhcp3-server fails to issue lease after computer has gone to sleep and woken back up

[Soap Star Joe]

Binary package hint: dhcp3-server

After I put my laptop to sleep and wake it back up, it fails to issue dhcp leases until i restart dhcp3-server. Ubuntu version is 8.04, dhcp3-server version is 3.0.6.dfsg-1ubuntu9.

is the dhcp server running on the laptop? thats what it sounds like from your report (but that would be a bit odd)
whats is the dhcp server running on if not the laptop?
has the laptop dropped its inital ip when it sleeps, and refuses to get a new lease on boot?

the laptop is the dhcp server. I use it as a router to connect my desktop to my wireless network. I usually put them to sleep while i'm at work during the day and wake them up when i come home. however when i wake them back up, my desktop isn't able to get leases/contact dhcpd until i restart it on the laptop. I ran tcpdump on the lan connection on the laptop and watched dhclient on the desktop ask for a lease without the laptop issuing a reply. I tried restarting the desktop/cycling network manager to no avail. the desktop is able to ping the laptop/ssh to it when i configure it with a static IP in this state, it only cannot get a dhcp lease. however, after i restart the service on the laptop, everything works perfectly.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

sorry for the delay. The issue isn't persistent since 9.04--best i can tell
dhcpd now remains associated to network adapters across sleep.
