So, Im working on a project, and I know the OLSR does some checking / beaconing of the local routers connected. What I am trying to do is build a script that will do much the same, only using figures and info input via a PHP form, along with some other device stats. Can anyone give me some insight, or a point in the right direction with this!!

Sound like you are thinking it through and should go well, hope I gave you enough to ponder to understand the final plan and knowing where the limits are. Of course I realize as I put all those questions in I might cause you to make the mistake I often make, waiting for everything, often the solution that exists is better than the solution that is still being built.  Take it in stages with the grand scheme in mind and hopefully you won't have to wait till next December to have something to work with.

Good luck!

Update: Please do not alter the BBHN firmware for this one particular case. Instead, I will write a Perl (or Python) script to parse the URL passed by BBHN and rewrite the URL in a format compatable with the target camera. And then have Firefox call the script to execute the video streaming client. Not a big deal.

The only downside to doing it that way is that the script would have to be installed on all computers needing access to the video stream from the camera.

Maybe I missed it...what is the make and model of the camera?

AE6XE, thank you for the input. I have been testing the various aspects of the camera and it's interaction with the mesh node URL.

Update: I found a better streaming video client for Firefox. It is called "mpv". The camera insists on getting account / password before it will stream the video. With mpv, I can manually pass all the information in one URL, but the URL is more involved than what a BBHN link will pass to Firefox.

What the BBHN link passes:   rtsp://IPC:554/live

(Where IPC is the configured server in the BBHN node, 554 is the streaming port,  and '/live' is the extra connection info)

What the camera will accept is:   rtsp://[account:password]@IPC:554/live

(An 'mpv' example with a blank password:    mpv rtsp://iwantvideo:@IPC:554/live)

The 'iwantvideo' would be an account configured on the camera in the above example.

If I can get the URL formatted correctly from the BBHN node link, it would be simple to configure Firefox to use 'mpv'

My thanks to everyone who has helped so far.

You may want to be careful with the choice of HTTPS/SSH as both are encryption that obscure the message, it tends to be a hot button topic with many ops and may create some interesting discussions, some times its just easier to avoid having to discuss.

The bigger items I want to bring up are to help you think the scenarios here for the bootup (these are ask your self questions not  questions I'm asking for answers on)

What happens when 2 networks are isolated and than become joined?  Do you run two masters at that point?

Why are you separating the services away from a single node? Is this really an advantage?(note: i want to quantify that 'distributed' design of loosing maybe the file server but not the chat server at the same time DOES count as an advantage) 

What do you consider a 'load'?  We can talk CPU load, we can talk network load etc.

Have you thought about the services trying to move to a more central in the network node based on routing data (a node in the center of the network will give you much better network reliability than a node at the far end of the network)

Everything was working great and someone bumped the power at one of the boxes, the box that has been controlling one of the services (and has all the data)  reboots quickly, but now has an uptime of minutes, what about its data set? Is it being published around or can the network rebuild that data?

Essentially you are talking about Cluster management for an Active/Passive infrastructure with a highly dynamic topology... Very powerful when done right, very code intense to build right. Just wanted to get your brain stirring, the idea sounds good in concept, just wanted to give you ideas on things in the backend to think on.

The basic services you want to offer sound exactly right and provide a method to hopefully make life easier for you, just an implementation item.

So, Im a soldier, and I live in an earthquake/tsunami zone. We have these things called EBOX's, they are a sea containor with some survival equipment and supplies. They are situated around the base to support various numbers of people in various units incase of an emergeny like the ones listed above.

Simply put, their communications system is VERY ineffective. Basicaly there is a CB with a mag mount to toss up on the top of the container. then there is the process of reporting in.... That quickly turns the whole comms setup into a giant crap shoot. Everyone is panicing, wants their turn NOW, and none of them follow any kind of rhyme or reason as to what and how they report that into... Who's listening?? lol So, I am devising a Mesh system to utilize in my community which also has these same EBOXs, but also has ham radio operators associated wtih them.

What I am working on at this point is to have a Raspberry PI act as a host for a local webpage that looks like the images attached to this post. Each EBOX will record its boot time, this boot time will help determine the operation of the services mesh provides. As in, even if EBOX1 boots at 9:00, that doesnt mean its the control host of the (HTTPS & IRC). EBOX8 May have been booted first, at 8:55. Making it the control host. The services being hosted across the mesh are, an IRC, PBX, GeoServer, HTTPS, and hopefuly a method of file sharing.

The reasoning behind determining the boot up sequence, is so that not one node is responcible for all of the load of the services. Services will be booted in a predetermined sequence according to priority. Each node will have to run the HTTP service for their local operation, I will need to decide what to use for reporting.. SSH??.. After that, the next node will run the IRC, then GeoServer, then PBX last. This would requier at least 4 nodes to be fully functional. If I impliment a system to check time and load, the distribution of non-operating services can be started by the nodes with the least amount of load after say a 30 min count down.

This "Load balancing" and "Boot Sequencing" doesnt make any one node the Control Node. A, for lack of better terms, rank structure will dictate what individual is the Controller, and thus wich node is the control node. Just as most nets are operated.

The layout, and basic function of the site I am okay with. How ever, the integration of the rest is going to be the part I need the most work on. Such as, the reporting of individual nodes, and those stats showing up on the other remote nodes in the master tab. i know there is a lot of work to be done, and I will do what I can. I may be asking for assitance or ideas as I go.

For anyone who may not know... the GeoServer application I wish to use, is a kind of standalone, opensource "Google Maps". It has GPS integration, and does not requier an internet connection to operate once it has been setup. The maps are localy stored, and accessable without the need of any outside sources. Which makes it great for this kind of setup.

Any suggestions, or insight are greatly appreciated!

Thank you for reading!

Memo to Larry:  Attend the local ARC meetings once in a while!!    Apparently locally they are using NW-MESH firmware based on the OpenWRT Attitude Adjustment RC1 release.

A local web site I found is below:  (Stevensville  and Hamilton, MT area)

http://www.meshstuff.com/hsmm-mesh-site/

Since winter has descended upon us here, I doubt whether anyone is interested in updating now.   Good project for the summer, though.  I'll see if I can make contact locally and find out what the plans are.

Larry

Yes. However, I would advise that the some 15 stations be placed in a queue for update.

I have two node stations in operation,  W0AY-1 (resurrected  Linksys) and W0AY-2 (new Ubiquity AirGrid) up and running on 2.4 GHz Ch 1.  The two nodes can see each other and W0AY-2 located on my deck can see stations from the local mesh network.   But, as far as I can tell,  my W0AY-2 (air Grid) didn't join the local mesh.   Why?  Is it because my two nodes SSID as Broadband-Hamnet with version #  and the local mesh ids with an SSID of   HSMM-MESH?  I recall, I think perhaps incorrectly,  that the SSID's of all the mesh members must be the same?   If so,  I can't locate a way to change the SSID because the web interface automatically adds the version number.

Thanks for any help,

There is a section 97.311 Spread Spectrum (or bandwidth-expansion modulation emissions) which is designated for many bands including 70cm. This does give some precedence for 5MHz+ channels and other 802.11 protocols.

While bbhn may not have any direct control over the 802.11 low levels protocols used, SS is one of them. It seems unlikely that the 97.37(f)(6) intent would apply to 802.11 protocols, because all this language is around symbols at 1200/300 baud.

The ATV channels on 70cm are 6Mhz wide and also sets a precedence on bandwidth usage. Many of these folks are no doubt looking at bbhn and locally have already put a mesh node on the ATV tower.

My opinion is that experimenting with bbhn on 70cm is fully in the spirit of ham radio, BUT as long as the ATV and bbhn folks are talking, getting alone, and sharing the band, there would be opportunity. Let's not go throw up a node and trash a well established ATV used space (well, it's more like ATV will completely trash the low power bbhn).

Locally, Don KE6BXT is working to integrate a VOIP-video device with analog video feeds to bridge the traditional ATV repeater with the local mesh. ATV folks are drawn to video over bbhn...

Yep! It DOES seem like this forum is becoming MY Blog . I forgot to mention that I'm still looking at Web mail as part of the Web page but that still needs to be evaluated. I need to determine if the various offerings have to be kept separate or if I can offer multiple services off a single server on a PI. Interesting project and my little MESH hasn't even gone public yet. Can't wait to register it. And yes, it is indeed "So far so good." My avoiding both Linux and Raspberry (because of Linux) was pretty much based upon a history of disappointments with Linux. It simply did not get along with ME. What the root cause was, I don't know. However, as I said, it's turning out to be much more fun than I anticipated. Howard W6IDS Richmond, IN
