MESH-PI (HSMM-PI)

I wasn't going to do this now but with the need for the old-house-cam and the potential that it would fit right in, that was all the excuse I needed. I think the final nudge was the easy of getting MRTG running on a RPI so I could track the mesh traffic like I've been tracking local 9600 Packet.

Goal: Get NW-MESH running on a RPI so I can access the old house cam from the web.

Here's the project home pages are at wordpress HSMM-PI and GITHUB HSMM-PI for discussion there is aGoogle + Community


TODO Next:

Reload PI SD card with last summers Image. Don't update it. Try installing version 2.0 of HSMM-PI with the update disabled. Theory has it that this will work with the boguss WIFI card.

Reload PI SD card with the latest RPI image. Update it. Fire up the AE2500 dual band dongle. Install version 3.0 of HSMM-PI.

TODO Someday:

Learned:

Had to make /root chmod 777 instead of the 440 it was set in the script - Yes I know, that's not secure. Fix it someday will I.

Issue 2

Edimax WIFI card won't work.


LOG:

3/27/2014 - Learned from Rusty that my RF WIFI was most likely at fault.

3/26 - postings on last nights efforts.

Rusty: Bill, despite there being 32 ASCII characters in the old HSMM-Mesh key file, '/etc/olsrd.key' (well, current one too), only the first 16-characters are read (or have ever been read)

Bill: I can confirm that only the first 16 characters are needed for the key. Didn't help with MESH on the RPI so I'm backing up and going to try a different radio (AE2500) with it.

Rusty: You weren't using an Edimax or one of the other 2-3 dozen of the RealTek RTL8192CU chipsets in it, were you? If so, and using one of the last two releases of Raspbian, I can assure you it won't work. The Secure Plugin key has nothing to do with it.

Bill: Bingo... Exactly as I discovered. "Dongle is Edimax EW-7811Un 150 Mbps Wireless 11n Nano" Will try the Cisco AE2500 tonight and order something supported later if that doesn't work.

Rusty: I went back to the Sept '12 release of Raspbian and disabled the 'apt-get upgrade' in HSMM-Pi's 'install.sh' script. Worked just fine with the Edimax.

Bill: Good idea - Thanks! I have a RPI install image from last July I could take for a test drive. Should work as long as I'm careful with the 'upgrade' calls. Would love to have this running for the MicroHams show on Saturday - specially if I can get SNMP/MRTG showing the network traffic like I do on 9600 packet.

Rusty: I do know that at least most anything with an Atheros chipset works with the latest Raspian. I'm currently using a TP-Link TL WN721N with the latest release. The 722 has a detachable antenna, I believe.
