 1 | # MeshChat
 2 | 
 3 | MeshChat for AREDN (in Lua). MeshChat has become the defacto standard
 4 | chat application for AREDN networks. A number of features make it easy
 5 | to implement and use:
 6 | 
 7 | * Installable on AREDN firmware and most any Linux distribution
 8 | * Automatic synchronization between nodes using the same service name
 9 | * No account creation necessary--users access using call sign
10 | * Simple user interface
11 | 
12 | If you are looking for a feature to be implemented or find a bug, please
13 | be sure to [create an issue](https://github.com/hickey/meshchat/issues/new)
14 | in the project so that it can be prioritized.
15 | 
16 | Current documentation for MeshChat can be found at:

/docs/History.md:
--------------------------------------------------------------------------------
 1 | # History of MeshChat
 2 | 
 3 | This is the history of the various MeshChat versions that have existed--at
 4 | least to the best of my knowledge.
 5 | 
 6 | ## MeshChat v0.4 - v1.02
 7 | 
 8 | This was the original version of MeshChat written by Trevor Paskett (K7FPV)
 9 | around 2015. 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 | 


--------------------------------------------------------------------------------
/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 | 


--------------------------------------------------------------------------------
/docs/Troubleshooting.md:
--------------------------------------------------------------------------------
 1 | # Troubleshooting
 2 | 
 3 | This is a "living" document. 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.<ZONE NAME>`. 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.
