I forklift upgraded from 3.10.24-8 (I think), to 3.10.36-4 today.
Forklift, because I factory flashed my spare unit with .36, uploaded the
backed up configuration, and then swapped.
1) I figured out my problems with SSH to the device. Nothing malicious,
it turns out that ssh to 42.1 is accepted only if you are on the 42.x
network, which I *thought* my desktop was via a VLAN, but it turns out
that it wasn't. So the ssh was going in via a different port, and
connecting, and then dropbear was (correctly!) disconnecting. More
logging needed there.
2) dnsmasq did not start properly.
First the problem seemed to be that odhcpd was running, so port 547 was
busy (DHCPv6 server port). Should it be running? where would I have
I killed it off, and ran /etc/rc.d/S35odhcpd disable, and then
I got a complaint that the /var/lib/misc/dnsmasq.leases could not be
created. We need to have:
mkdir -p /var/lib/misc
in the start up scripts, and somehow we also need to have some way to
see how daemons are being started up. The /etc/rc.common stuff creates
a huge verbosity if you set -x things.
Given how import dnsmasq is, it really really needs to never refuse to run.
I'm gonna power cycle the unit and see if it comes back okay.
