[CUWiN-Dev] Re: much simpler upgrades

[tom]

I tried this last night, with some success. I can find the IP of a couple of 
the nodes, but couldn't manage to connect to any of them. Manually setting 
my IP address to be on the same subnet and then trying to SSH into them over 
the air resulted in "no route to host" messages. What *did* work was getting 
a DHCP lease from the access point that people have plugged into their nodes 
and then using that connection to SSH into the node. From there I ran into 
trouble actually doing the upgrade, for whatever reason it would go through 
the procedure of installing the upgrade but then would spit SSH error 
messages at me. I didn't have time to try that more extensively, though, so 
it might not be a big issue.

A couple things:

1. I thought the cuwireless.net SSID corresponded to a 169.254 address and 
cuw to 10.0 - is that not true? I mostly saw cuwireless.net SSIDs, but 10.0 
addresses. I don't know when the IP switch took place, so maybe its not 
related to the SSID switch at all.

2. Outside of 707 Race I picked up what appeared to be almost a dozen 
cuwireless.net nodes - all with similar mac addresses. Is this due to one of 
the nodes changing its mac around? I don't think there should be that many 
visible from there.

3. I'm going to start compiling a list of the nodes' IP addresses as I 
figure out what's what. Where's the best place to put this, on the wiki?

I'm going out of town this afternoon through Sunday, so I'll continue trying 
things once I get back.

That sounds perfect.  Our routers are distinguished by their IP, either
10.0.x.y or 169.254.x.y, and by sending UDP packets on port 9191 (HSLS),
and/or OSPF packets.
