Looking at the below abstract from the #Reticulum manual brings the following ideas/questions to mind: How hard would it be to modify a #nostr relay to allow connections to/from a #Reticulum network? Along the same lines, how hard would it be to modify a #nostr client to utilize a #Reticulum network as a transport?
#asknostr #strfry #nostrrelay #nostrclient #meshnetwork
Pipe Interface
Using this interface, Reticulum can use any program as an interface via stdin and stdout. This can be used to easily create virtual interfaces, or to interface with custom hardware or other systems.

My self-hosted #Nostr #Relay logs were growing, growING, GROWING!
So I set out yesterday to determine exactly what was going on.
Guess what I found?!? A handful of clients from different IP addresses were causing a continuous stream of error messages where the relay was complaining of a "filter item too small".
So I tweaked the logging settings to get dumps of the requests generating the errors.
Each error entry looked like the following:
[Ingester 0 ]INFO| [21] dumpInReq: ["REQ","6zn9yubmmkm557n78kkta2e7aahjbn",{"since":1746216000,"authors":["00","01","02","03","04","05","06","07","08","09","0a","0b","0c","0d","0e","0f","10","11","12","13","14","15","16","17","18","19","1a","1b","1c","1d","1e","1f","20","21","22","23","24","25","26","27","28","29","2a","2b","2c","2d","2e","2f","30","31","32","33","34","35","36","37","38","39","3a","3b","3c","3d","3e","3f","40","41","42","43","44","45","46","47","48","49","4a","4b","4c","4d","4e","4f","50","51","52","53","54","55","56","57","58","59","5a","5b","5c","5d","5e","5f","60","61","62","63","64","65","66","67","68","69","6a","6b","6c","6d","6e","6f","70","71","72","73","74","75","76","77","78","79","7a","7b","7c","7d","7e","7f","80","81","82","83","84","85","86","87","88","89","8a","8b","8c","8d","8e","8f","90","91","92","93","94","95","96","97","98","99","9a","9b","9c","9d","9e","9f","a0","a1","a2","a3","a4","a5","a6","a7","a8","a9","aa","ab","ac","ad","ae","af","b0","b1","b2","b3","b4","b5","b6","b7","b8","b9","ba","bb","bc","bd","be","bf","c0","c1","c2","c3","c4","c5","c6","c7","c8","c9","ca","cb","cc","cd","ce","cf","d0","d1","d2","d3","d4","d5","d6","d7","d8","d9","da","db","dc","dd","de","df","e0","e1","e2","e3","e4","e5","e6","e7","e8","e9","ea","eb","ec","ed","ee","ef","f0","f1","f2","f3","f4","f5","f6","f7","f8","f9","fa","fb","fc","fd","fe","ff"]}]

The culprits were trying to request a list of articles with an author list that basically covers every possible Nostr ID... Or something along those lines.
If you're using a nostr relay you aren't paying for, remember to #zap your relay operator. They deserve a little love from time to time!

There actually is a global public network. I host a #public #reticulum node that you can connect to over the commercial internet: https://reticulum.n7ekb.net. It provides a bridge from my local low power RF-based (#LoRA) nodes to other RF-based networks. I also run a mobile RNode in my car that can use my mobile phone to tie it into the "global" network.

2025-04-13 14:20:15

Here's one for #asknostr: Filed in https://github.com/greenart7c3/Citrine/issues/61.
I run #Citrine on my phone (Thank-you!!!) and also run a personal nostr relay (strfry) on my VPS so that I have two locations for all my notes. These are entirely dependent on the commercial internet however. I also run a program called #Sideband which connects to the #Reticulum network using a locally hosted transport router for Reticulum. How feasible/difficult would it be to add support in Citrine to publish/interact with my local Reticulum transport? The Reticulum transport has a lot of options: Reticulum Interfaces. Such a feature would make nostr over Reticulum possible in areas where commercial internet is unavailable (#disaster/#censorship).

I've migrated from #Anytone to #Tytera. I use the MD9600 (a dual band analog/DMR base mobile radio at $220) and the Tytera UV-390 (also dual band analog/DMR at $120) as my handheld. Both radios came shipped with the #OpenGD77 firmware. This common firmware means I use the same #codeplug for all my radios, and the #DMR programming is #ham friendly with the OpenGD77 approach. These radios support #hamradio as well as commercial, so they meet my needs in the #EMCOMM space really well. (Our town's EOC uses DMR). I've found the UV-390 to be more rugged than the Anytone handhelds for daily carry, especially outside in rainy weather.

It's fun indeed! Most #meshtastic devices are easily converted to #RNodes for use in a #reticulum environment as well. Double the fun! https://reticulum.n7ekb.net

A lot of #hams ignore the other radio services which are often better suited for meeting the needs in some parts of a #disaster plan. You're wise in connecting the dots between the experimenting nature of #hamradio and the use of the knowledge gained there to solve real world problems with ALL the tools available.

Got my new VPS up and running this week. Transferring the various virtual host web sites was straightforward since I had full control of the old and new servers on the same hosting platform.
The switch from the old crusty #Rocky #Linux OS to a fresh new install of #Debian 12 has been really refreshing.
In addition to my websites, I also have a self-hosted #XMPP #Prosody #IM server, a #reticulum TCP router, and a personal #NOSTR relay.

First time booster and regular listener via the AntennaPod app on my GrapheneOS phone. The show keeps me entertained while I drive an 18-wheeler all around the metro area based out of Algona, WA. Thank-you for what you do! You mentioned a network challenge in a recent show. How about taking your meshtastic experience up to another level? There's a far more solid mesh protocol called Reticulum with some interesting apps built on top of it like reticulum-meshchat, Sideband, rnsh, rcp, and nomadnet. So here's the challenge: re-flash those meshtastic devices, turning them into RNode devices. Then build out a test network over LoRa and TCP/I2P/Serial/AX25. Maybe give points for things like sucessful rnsh (like ssh) connections that hop over at least one or more LoRa hops. After you read up a bit on Reticulum, I'm confident the team can come up with a great challenge that will demonstrate how Meshtastic vs Reticulum is sort of like Windows vs Linux. :)

I actually read just the opposite from someone who posted about their test results. Higher SWR with the 90 degree angle versus straight. Antennas, feedlines, and RF are so fickle.

#Reticulum would be a better suited protocol for this application.

The #Reticulum Network World #Map Project went live today:
https://rmap.world/index.php
I'd like to see some #EMCOMM minded #hamradio sites show up on this map. In theory #EOC client computers running reticulum-meshchat day-to-day would have transparent fallback to RF-based connectivity when their commercial TCP network goes away in a #disaster event.

That's right. #reticulum firmware 1.81 is what I used.

Its a bit early to say. I live in a rural area with lots of Douglas Fir trees, so 900 MHz radio signals don't travel very far - even with the magic of LoRA low-power propagation. The 4 RNodes I currently have on the property are happily meshing together and waiting for more neighbors. If I could just get a node up on a mountaintop... In the meantime I'm using the internet as a stable gateway to other RNode networks.

2025-02-16 03:59:12

Got this new LilyGo T-Echo device yesterday with #meshtastic firmware. Promptly reflashed it with #reticulum #RNode firmware 1.81. I paired this RNode with my phone running #Sideband. I finally stumbled across the "Popular RNode Settings" page in Mark's wiki on github. Now I have my RNodes operating on 914.875 MHz with a spreading factor of 8 so they'll be more likely to #mesh with other people's RNodes in the 900 MHz #ISM band. Looking forward to #wardriving some of the areas I frequent with this new RNode.

I converted my third #meshtastic node to an #RNode today so I can use it as a future portable/mobile node. My #Linux #hamradio shack PC has both an RNode and high-speed TCP connectivity and is acting as a dedicated bridge between my RNode-based reticulum network and the public internet TCP-based #reticulum network. I tweaked the mode settings on the different interfaces in the ./reticulum/config files to use the #gateway and #boundary modes were appropriate. You can see the modes on the status page at https://reticulum.n7ekb.net.
For #nomadnet I setup a second node so that my rnode-based network has it's own node on the #hamradio shack PC. Look for "N7EKB's RNode Network Node" and "N7EKB's TCP Network Node" in the announce stream on the #Nomad Network.
The screenshot is of Liam Cottle's #MeshChat program running on my #Fedora #Linux laptop connected to the TCP Server interface of my #hamradio shack PC. MeshChat is an AWESOME program Liam!

LOL. The node reticulum.n7ekb.net is indeed only using TCP on the commercial #internet since it's running on a VPS in a data center and also hosting my web pages.
You inspired me to create a couple of scripts to add the output of my hamshackpc #RNode status to the reticulum.n7ekb.net web page. My hamshackpc (computer running #fedora #linux) talks to the greater #reticulum network only via an #RNode based on the RAK4631. Another PC in the home network has both RNode and TCP connections to the reticulum network.
I put the output of the #rnstatus command from the hamshackpc into a file. Then I'm using the #reticulum utilities #rnx and #rncp to move the file from the hamshackpc over the two RNode connected PC's and onto the web server where the #php page can display the contents! The transfer script runs every five minutes via a crontab entry. 😀

I'd like to build a network with TCP connections to other #hamradio nodes worldwide. Reply to this note with your host:port info and I'll add you to my connections.
I have a couple of #meshtastic devices that I've reflashed as #RNodes that will be joining soon as local RF connections.
