Topic : 44.0.0.0/8 ?

I am working on getting assigned 44.86.x.x IP addresses, However I am unsure how they will fix with any HSMM I deploy, I'm new to ham radio only getting my tech license this month, but I am diving right in to the topics that interest me the most, which are AMPRnet and HSMM. I understand HSMM not being a replacement for home/business internet, but in what cases is it acceptable to attached an internet gateway onto a HSMM mesh. Surely if the Red Cross needed to access internet resources and other communications where down this would be acceptable. I don't know about Internet gateways for more generalized usage. I was hoping ad5oo could share some of his personally thoughts on this.

Topic : Can't connect to OSLR Status of Neighbor Mesh Nodes

I see you are using the http://172.27.0.1:8080 URL to connect with your node.  This works as it should, but you should instead use http://localnode:8080.  If this doesn't work then you have a DNS problem.  It may still be possible to connect with http://localnode.austin.tx.us.mesh:8080 . If that doesn't work either then you have even more serious DNS problems.

Sometimes Windows does not do as it is told.  Sometimes it is configured in a way not entirely compatible with the proper use of DHCP supplied network parameters.  It may be just a simple issue of renewing your DHCP lease, which I have had to do myself on Windows (but never on Linux).  Otherwise you need to examine your TCP/IP configuration to see what may be preventing DNS from working properly.

I fully expect that if you go to http://10.1.2.3:1978 (substitute the actual address for W4BGH-002) it will work.

Topic : 44.0.0.0/8 ?

The 44.0.0.0/8 subnet, otherwise known as the AMPRNet, is a public address space and is in large part already allocated to other hams and regions.  As a public address space, these addresses are routable from the Internet, as are all other public addresses, and this is their purpose.

On the other hand, any mesh is a private network which is not dependent upon Internet routability.  The 10.0.0.0/8 address space is already set aside for this purpose, does not conflict with existing Internet addresses, and is the only IPv4 space large enough to adequately allow for automatic address assignment on a large scale.  The ability to connect to the Internet is generally considered a desirable thing, and to do so one must play by the rules of the Internet.

Topic : Thanks

Thanks to the encouragement at SummerFest and the very nice documentation on the HSMM-MESH website, I have a tiny mesh network running here on the east side of Lake Buchanan.  It does not connect to much except itself, but I have enjoyed putting it together and configuring it. 

It did take me a while to get the routers - the Austin Goodwill Computer Store was a bust each time I tried, so mine came via eBay ($20 to $32 - but no gasoline expenses!). 

The next project is to get a little video going so we can keep tabs on the deer.

If I can help in testing or whatever, please let me know.

Am I missing something? So far I have not seen anyone use the 44 block for their mesh network. Is there a reason for this?

Topic : Can't connect to OSLR Status of Neighbor Mesh Nodes

I am just getting started and have configured two Mesh Nodes, called W4BGH-001 and W4BGH-002.  W4BGH-001 is a WRT54G V4 and W4BGH-002 is a WRT54GS V4.  The firmware installation seemed to go well.  I have W4BGH-001 configured as a Mesh Gateway connected via the WLAN port to a switch behind my Verizon Actiontec router.  W4BGH-002 is connected via a LAN port and CAT5 to my netbook showing an IP address of 172.27.0.5

I can connect to the Internet from my netbook just fine…so far, so good.  When I connect to http://172.27.0.1:8080 from the netbook I get a status page that shows the Default Gateway as W4BGH-001.  When I click on the Mesh Status button I see W4BGH-001 as a neighbor with an active link.

When I click on the W4BGH-001 link I get a “server not found” error failing to connect to http://W4BGH-001:8080/.  Also when I click on the OLSR Status button I get a “server not found” error failing to connect to http://W4BGH-002:1978/.  This doesn’t seem normal, but I can’t figure out any work-around.  I have tried two browsers: Firebox and Internet Explorer.  Any suggestions?

Well, All I had to do was read ahead a bit. All three working now! Ready to explore.

I'll try to learn how to pass some kind of traffic now.


Thanks Again!

Topic : Lost Setup Access via LAN

I have a couple Nodes working, but am just learning. A third one, I have lost contact with. In my learning process, I changed the node type from Mesh Node to Mesh Access Point. After I did this, I have not been able to get back in. My laptop sees the WIFI of the node, and I can connect to it via WIFI, but the URL I have been using does not work. 


A hard lesson..

Topic : can't access setup

I am just beginning and have just successfully programmed my first WRT54G router. I configured the mesh node per the instructions: I connected to http://172.27.0.1:8080 then clicked Setup with UID=root and PSW=hsmm. I entered a Node Name=W4BGH-001 with my password. I saved the changes and the node rebooted. Now I can once again connect to http://172.27.0.1:8080 in a browser and see the HSMM-MESH Node W4BGH-001 status page, but I cannot return to the Setup page. It asks for a UID and PSW, but will not accept the original UID=root & PSW=hsmm or the Node Name=W4BGH-001 and my password. BTW, my computer is connected via a LAN port with the IP address 172.27.0.5 So what am I doing wrong? -73- Bernie W4BGH

Topic : updating/uploading firmware

Thanks for posting the specifics. Now we have this info in one nice sequence here in the forums. Briefly, one can set up a computer to down load new firmware using the "tftp" utility. This is tried, very briefly, when the WRT54G boots. They do not want to delay the normal boot for long, so don't give tftp much time to try to connect before continuing on to the normal boot. That is at the root of why I mentioned most would not consider tftp boot to be "easy". The default window to attempt a fw download is real short and I have missed it many times, before getting both the down load computer and the router both synced closely enough to allow the tftp down load to work. Making the wait time longer makes the tftp much easier to do. Once you get back with a good firmware load, you might want to put the bootwait back to the quick default. The WRT54G can normally reboot in about 35 to 45 seconds. If you add another 10 seconds for boot wait it is not a killer, but most would notice the node booting more slowly than some. All good info. If these techniques do not work, there is still the JTAG port but that is a whole article in itself with some hardware to build. Alas some of the used units I have collected, seem to have insidious intermittent hardware problems. They are not completely dead, but even after fooling with them for hours, they crap out at unexpected times. If you have bad hardware, software techniques can't fix them. -Glenn KD5MFW

Topic : updating/uploading firmware

Just FYI, here is how to edit the boot wait time. This should make it MUCH easier to to tftp as it gives it some time before it finishes booting. You don't have that 0.45768395 second window that you have to try to hit to tftp :) (yes, I am exaggerating, but you know what I mean...) Anyway: First, you need to SSH into the router. I use putty. If you have the program in your Windows path, you can use a command line in Windows if you want. Just remember, the SSH port is 2222. Login to the router with user 'root' and your password. Then issue the following commands: nvram set boot_wait=on nvram set boot_time=10 nvram commit && reboot

Good work. Glad you had some success. This is all good info. We can all hope fw changes go smoothly for everyone, but that is no always the case. This is good info to have on the forum pages for anyone else that runs into problems. The same tricks might fix their problem or give them an idea of another test to try. Thanks for adding to the support info with your comments. We have a few more helpful tricks to use. -Glenn KD5MFW

Topic : updating/uploading firmware

thanks... I found on another forum how to edit the boot wait time so after I figured that out, tftp worked ok. I also tried it just for grins and just renamed the .bin file to .trx and it worked fine that way too. Looks like either of those would work ...

Topic : updating/uploading firmware

The tftp method of access does work, but it requires considerable patience - considerable. The more advanced the topics you wish to experiment with, the more of a challenge you are taking on. I have flashed hundreds of the WRT54g routers, including all the models that will run HSMM-MESH firmware and have successfully used used tftp to get into them - as a last resort, before having to resort to using the JTAG port to pump code in. So it does work, most would not consider it "easy". None of the developers has enough lab gear to trace and explain all possible failure modes. I have had some very odd results on a few of the used units I have worked with. Without an in circuit emulator and a full JTAG development system, some problems are near impossible to trace. There is no telling what sorts of problems a unit that has had bad power or an over voltage surge, might have. Very few users have these sorts of problems, but I mention this in an effort to cover all cases. Intermittent hardware problems are a black hole for time. The documentation is here: This works, but it is an advanced technique and I have had to sometimes try it many times to get the timing just right for it to work. Good luck. -Glenn KD5MFW

it appears to have taken the 0.4.2 trx file ok... now, how can I get it to take Linksys again since the pinging sequence doesn't indicate a bootloader is listening for a tftp connection? At least not on the 172.27.0.1 IP...

No other package to load. Load the .trx version of 0.4.2. Use the .trx files to update a node already running a version of HSMM-MESH firmware. The .bin files are required for loading routers running Linksys factory firmware. Linksys had more than one load format so that is why there are multiple .bin files to move from Linksys to HSMM-MESH fw. Once you are running HSMM-MESH fw you can always use the .trx fw for all models. The fw is the same, it is just the loader checking at the start that gets mixed up. -Glenn KD5MFW
