[mihini-dev] Wiki Suggestions / telnet on port 2000

[mnerys@xxxxxxxxxx]

Hi Guilhem/All,

To make my message easier to digest,
I'll focus my feedback on this page:
http://wiki.eclipse.org/Mihini/Build_Mihini

where one can read:
# Move the result
of the build in
your HOME
$ mv
runtime ~/mihini

Followed by:
$ cd
~/mihini
$ ./runtime/start.sh

I believe that the intention in NOT
really to have a file like "~/mihini/runtime/start.sh"
and instead have something like "~/mihini/start.sh".
If a step-by-step guide is being provided and the idea is to have a "runtime"
in "~mihini", maybe there should be a "mkdir mihini"
at some earlier point, but other instructions (like
http://wiki.eclipse.org/Mihini/Run_Mihini_on_an_Open_Hardware_platform
: sudo
./bin/appmon_daemon -a /home/pi/mihini/start.sh
...) makes me believe otherwise (that there should be no "runtime"
inside "~/mihini").

Assuming the idea is to get the "runtime"
contents and place them as "~/mihini", then there should be no
"runtime" before the "start.sh" call. I hope I made
myself clear. :)

--

Next, after the "start.sh"
is invoked on the "Check that everything works" section and the
user verifies the output, it would be great to put a note stating whether
he should leave the service running or not (before going back to the main
tutorial). I assume the user should stop Mihini, since on the Main Tutorial
he'll be going to Step 2 (Configuring Mihini) and then Step 3 (Starting
Mihini). So, a note about this would make it more clear if he should kill
the recently launched process or not.

--

On the "Run the compilation"
section, maybe you can update to include the recently added gpio module.
I tested it here and a "make gpio" right after "make modbus_serial"
worked like a charm.

--

Last, but not least, right after running
the "start.sh", it would be great to add some verification info,
like suggesting the user to use "telnet localhost 2000" and/or
"telnet <raspberry_pi_IP> 2000" from the Pi and from an
external host to validate the service is accessible or not. On my tests
here, at this point the only successful telnet is the "telnet localhost
2000" from the Pi itself. When I try the IP, no telnet works (neither
form the Pi, nor external). Firewall should not be an issue, since I can
successfully use ssh to connect to the Pi. Debugging info on this can be
seen below.

--

Killing the start.sh (with ctrl+c) and
doing:
cd ~/mihini/lua/agent
mv defaultconfig.lua defaultconfig.lua.bak
wget https://raw.github.com/nim65s/mihini-repo/CPack/porting/raspberrypi-linaro/agent/defaultconfig.lua
mv platform.lua platform.lua.bak
wget
https://raw.github.com/nim65s/mihini-repo/CPack/porting/raspberrypi-linaro/agent/platform.lua
cd ~/mihini
./start.sh

did not resolve the issue with the connection.
>From a remote machine, I still get:

telnet 9.7.229.151 2000
Trying 9.7.229.151...
telnet: connect to address 9.7.229.151:
Connection refused
telnet: Unable to connect to remote
host

and nothing new appears on the console
there the start.sh is running.

ssh pi@9.7.229.151 works fine.

Thanks!

pi@raspberrypi ~/mihini $ ./start.sh
