It was written in Perl and worked well on the limited resources 10 | of the AREDN nodes. Around 2018 Trevor was not able to or not interested 11 | in supporting MeshChat any longer, it is unclear which but the project 12 | became stagnant at version v1.01 in August of 2018. There was a final 13 | release of v1.02 in September 2022 that mostly added a few patches and 14 | support for Debian Stretch. 15 | 16 | The K7FPV code base still exists at https://github.com/tpaskett/meshchat. 17 | 18 | In addition Trevor wrote a good amount of documentation for his versions 19 | which is still pretty well covers the current versions of MeshChat. 20 | The documentation can be found over at his blog, https://github.com/tpaskett/meshchat. 21 | 22 | ## MeshChat v2.0 - v2.10 23 | 24 | When AREDN firmware v3.22.6.0 was released in June 2022, the AREDN development 25 | team stopped including Perl in the distribution in favor of LUA. In preparation 26 | of this change Tim Wilkinson (KN6PLV) started rewriting MeshChat in LUA 27 | March 2022 with the first release of the new code base in April 2022. The 28 | new MeshChat code continued to receive bug fixes for a year. At which 29 | time Tim's involvement on the AREDN development team prevented him from 30 | continuing to maintain MeshChat. 31 | 32 | ## Future of MeshChat 33 | 34 | That brings the story upto the current time, September 2023, where I, 35 | Gerard Hickey (WT0F), have started to be the maintainer of the MeshChat 36 | code base. There has already been work to restructure the repository to 37 | make working with the code more effective and to automatically build 38 | packages when a release occurs. 39 | -------------------------------------------------------------------------------- /.github/workflows/publish-docs.yaml: -------------------------------------------------------------------------------- 1 | name: Publish MeshChat Documentation 2 | on: 3 | workflow_call: 4 | inputs: 5 | build_version: 6 | required: true 7 | type: string 8 | 9 | jobs: 10 | build: 11 | runs-on: ubuntu-latest 12 | container: 13 | image: jtackaberry/luadox:latest 14 | steps: 15 | - uses: actions/checkout@v4 16 | with: 17 | fetch-depth: 0 18 | ref: release 19 | - run: luadox -c luadox.conf 20 | - name: Fix permissions 21 | run: | 22 | chmod -c -R +rX "_site/" | while read line; do 23 | echo "::warning title=Invalid file permissions automatically fixed::$line" 24 | done 25 | - name: Update version strings 26 | run: | 27 | find docs -type f -exec sed -i "s/%VERSION%/${{ inputs.build_version }}/" {} \; 28 | - run: | 29 | echo ::group::Archive artifact 30 | tar -C "_site" \ 31 | -cvf "$RUNNER_TEMP/artifact.tar" \ 32 | --exclude=.git \ 33 | --exclude=.github \ 34 | . 35 | echo ::endgroup:: 36 | - name: Upload artifact 37 | id: upload-artifact 38 | uses: actions/upload-artifact@v4 39 | with: 40 | name: github-pages 41 | path: ${{ runner.temp }}/artifact.tar 42 | retention-days: 1 43 | if-no-files-found: error 44 | 45 | # Deploy job 46 | deploy: 47 | needs: build 48 | 49 | # Grant GITHUB_TOKEN the permissions required to make a Pages deployment 50 | permissions: 51 | pages: write # to deploy to Pages 52 | id-token: write # to verify the deployment originates from an appropriate source 53 | 54 | # Deploy to the github-pages environment 55 | environment: 56 | name: github-pages 57 | url: ${{ steps.deployment.outputs.page_url }} 58 | 59 | # Specify runner + deployment step 60 | runs-on: ubuntu-latest 61 | steps: 62 | - name: Deploy to GitHub Pages 63 | id: deployment 64 | uses: actions/deploy-pages@v4 # or specific "vX.X.X" version tag for this action 65 | -------------------------------------------------------------------------------- /docs/Install.md: -------------------------------------------------------------------------------- 1 | # Installing MeshChat 2 | 3 | MeshChat is distributed as an Itsy package (IPK file) to be installed on an 4 | AREDN node. This is the simplest way to install MeshChat. 5 | 6 | Simply download the MeshChat package to your compute and then access the 7 | Administration panel in the AREDN's node setup. Under Package Management 8 | you will have the option to upload a package. Once uploaded the MeshChat 9 | system will be started within a couple of seconds. 10 | 11 | Usually there is not really any configuration that needs to be done, but 12 | review of the [configuration settings](../module/meshchatconfig.html) is 13 | suggested. 14 | 15 | Starting with `v2.12.0` the configuration of MeshChat occurs in the file 16 | `/www/cgi-bin/meshchat_local.lua`. Any configuration settings that need 17 | to be modified need to be entered into the `meshchat_local.lua` file and 18 | not in the `meshchatconfig.lua` file that previous version used to 19 | configure MeshChat. Making changes to `meshchatconfig.lua` will be lost 20 | when MeshChat is upgraded or downgraded. Making changes to the configuration 21 | still requires one to SSH into the node and edit `meshchat_local.lua` 22 | directly. 23 | 24 | ## Setting the MeshChat Zone Name 25 | 26 | MeshChat uses a zone name to locate other MeshChat servers running with 27 | the same zone name. Once servers are added to the same zone name, they 28 | will automatically synchronize their message databases with one another. 29 | Setting the zone name is done in the AREDN node adminstration settings 30 | under the advertised services. 31 | 32 | After a new install of MeshChat the installation will randomly generate 33 | a zone name and register it with the AREDN node. The service name 34 | (i.e. zone name) can be changed to the desired zone name used by other 35 | MeshChat servers. Once the service name has been saved, it is best to 36 | reboot the AREDN node to insure that MeshChat is restarted with the 37 | correct zone name. 38 | 39 | ## Installing MeshChat on Linux 40 | 41 | The current distribution of MeshChat does not currently support Linux. In 42 | order to run MeshChat on a Linux machine, one needs to download MeshChat 43 | v1.0.2 and install it on the Linux machine. Once installed, the configuration 44 | need to be updated to set the `api_host` setting to the hostname or IP 45 | of an AREDN node that has the MeshChat API package installed. 46 | -------------------------------------------------------------------------------- /api/meshchat: -------------------------------------------------------------------------------- 1 | #!/usr/bin/lua 2 | --[[ 3 | 4 | Part of AREDN -- Used for creating Amateur Radio Emergency Data Networks 5 | Copyright (C) 2022 Tim Wilkinson 6 | Base on code (C) Trevor Paskett (see https://github.com/tpaskett) 7 | See Contributors file for additional contributors 8 | 9 | This program is free software: you can redistribute it and/or modify 10 | it under the terms of the GNU General Public License as published by 11 | the Free Software Foundation version 3 of the License. 12 | 13 | This program is distributed in the hope that it will be useful, 14 | but WITHOUT ANY WARRANTY; without even the implied warranty of 15 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It is attempted to keep it up to date with 4 | any new problems and troubleshooting techniques. If you find something 5 | missing, please create an [Issue](https://github.com/hickey/meshchat/issues/new/choose) 6 | do describe what problem or issue is missing. Better yet is to fork the 7 | MeshChat repository, update the documentation in the forked repository 8 | and then generate a PR back to the official MeshChat repository. Your 9 | efforts will be greatly appreciated. 10 | 11 | It is important to realize that MeshChat is effectively two separate 12 | programs: one that runs in your browser (the frontend code) and one that 13 | runs on the AREDN node (the backend code or API). While it may not be 14 | obvious which piece of code is having the problem, it generally can be 15 | broken down as if there is an issue with the format of a message or it 16 | being displayed in the browser then the frontend code should be investigated. 17 | Otherwise the API should be investigated. 18 | 19 | ## Installation Issues 20 | 21 | There is a known issue that if an older AREDN firmware is being upgraded, 22 | any additional packages will need to be reinstalled after the node has 23 | completed the firmware upgrade. This should not be the case for AREDN 24 | firmware 3.23.8.0 or greater. 25 | 26 | If it appears that the installation of the package did not completely 27 | install or is not fully functional, check the node to determine how much 28 | disk space is available. Generally one should plan on a minimum of 100 KB 29 | of disk space for MeshChat to operate. 30 | 31 | Package installation failures also generally have an error message displayed 32 | above the upload button when there is a failure. This can help indicate 33 | what the failure type was, so it should be reported back as a project 34 | issue using the link above. 35 | 36 | ## Message Synchronization Issues 37 | 38 | In order for messages to be synchronized between MeshChat instances, the 39 | `meshchatsync` process needs to be running. Log into the node and execute 40 | `ps | grep meshchatsync` to see if the process exists. If it is not 41 | running, then one can start it with executing `/usr/local/bin/meshchatsync`. 42 | Doing so will keep the process attached to the current terminal and any 43 | error output will be displayed in the terminal. Once the terminal is 44 | exited, the `meshchatsync` process will terminate. So after determining 45 | that there are no errors being generated, it is best to reboot the node. 46 | This will allow `meshchatsync` to startup normally with no manual 47 | intervention. 48 | 49 | If it appears that `meshchatsync` is operating correctly, then the next 50 | item to check is that the message database exists and messages are being 51 | written to it. On an AREDN node, the message database is normally located 52 | in `/tmp/meshchat`. Check for a `messages.`. If the message 53 | database does exist, post a new message in the MeshChat instance on the 54 | node and insure that the message gets written to the message database. 55 | 56 | Also insure that the message database has write permissions on the file. 57 | 58 | -------------------------------------------------------------------------------- /.github/ISSUE_TEMPLATE/Bug Report.yml: -------------------------------------------------------------------------------- 1 | name: Bug Report 2 | description: File a bug for the MeshChat project 3 | title: "[Bug]: " 4 | labels: 5 | - bug 6 | - needs triage 7 | assignees: 8 | - hickey 9 | body: 10 | - type: markdown 11 | attributes: 12 | value: | 13 | Thank you for taking the time to create a bug report.
