Description

In the only box I've managed to keep running this long, dhcp has stopped serving new addresses.

root@labgw:~# uptime
19:39:04 up 5 days, 15:20, load average: 0.16, 0.06, 0.05

restarting dnsmasq fixed it. There have been multiple builds since then, of course, and I've beaten this machine up with many, many tests, and it used to have bug [#136] which I killed off by hand.

Strange. In the old build, I've got an uptime of around 20 days, and DHCP is working fine.

Let's try a new build out in the house I'm staying in tomorrow.

I'd like to figure out how to daisy chain these switches, as well.

Assuming the Testlab remains operation, I should able to slowly debug this.

Regrettably, there seems to be no way to simulate the problem, except time and multiple routers deployed. IT MAY be related to issue #147 and #145

As for "daisy chaining, or using the mesh" please open separate bugs for those.

I have multiple reports of the dhcp problem now. I am hoping that the switch patch fixes it,
but to test it fully I will have to hammer a router for several days from another router (or two or three) with dhcp queries.

Thankfully with the PDU coming online, if it hangs I can reset it.

I have several other related patches queued up, if that alone doesn't address the issue.
