When posting code, please use the Code blocks. Nobody will type over your script

[emme]

are you sure you have NC installed into your new hardware?

So what is shown in the domoticz log file? it should show at least the text: D.M.: IP Port check

Yep there is:

Code: Select all

2017-11-22 21:10:00.074 LUA: D.M.: IP Port check

Only no switching devices

[jvdz]

Ok, so do as emme stated: run the command from the command prompt (shell) on the domoticz server to see what the result is.

[Derik]

when i do the script on the old way..
Set a document in the script folder.
And activate it wit./name_of_script
Also in domoticz the same log.
Only no switching devices.

So i think i mis a package...
only what is NC?

[jvdz]

You could have done a simple google search to check that out.

Only i do not understand nc...?
And now i see

[jvdz]

So i am a bricklayer not a linux expert...

... but it seems you want to learn as you are participating in an English spoken Domoticz opensource community where one is expected to have an DIY approach.
I know it is easy for me to state this as I am working all my life in IT, so sorry for that, but when I started with Domoticz I had zero Raspberry knowledge and solely worked with big IBM Mainframes and any flavor of Microsoft OS. This meant for me to do a shitload of research on linux, domoticz, lua ESPEASY and took me around a year to get comfortable doing all the programming in LUA myself.

Just keep smiling and digging away and one day you get there.

I know...
I can use espeasy rpi openwrt autocad solidworks sketchup odriod domoticz minecraftserver windows office html etc..
Only lua i do not understand...
Like is say... runs for a few years..
A new setup, and not working any more...

when i run from putty:

Code: Select all

root@DietPi:/home/domoticz/scripts/lua# ./script_time_portcheck.lua
./script_time_portcheck.lua: regel 1: commandArray: opdracht niet gevonden
./script_time_portcheck.lua: regel 3: syntaxfout nabij onverwacht symbool '"D.M.: IP Port check"'
./script_time_portcheck.lua: regel 3: `  print ("D.M.: IP Port check")'
root@DietPi:/home/domoticz/scripts/lua#

So thanks for all te support...

You can't run the script from the command prompt as the eventsystem tables are missing when not shelled from the eventsystem.
Just add some more debug print() statements in the script in an effort to debug the whole script.
what does this script return in the logfile?:

Code: Select all

commandArray = {}

--print ("D.M.: IP Port check")

function update_portalive(name, ip, port)

    -- Windows https://joncraton.org/blog/46/netcat-for-windows/ untested

    s = "nc -z -w 1  " .. ip .." " .. tostring(port)
    print("debug:"..s)
    if (os.execute(s) == nil) then
        print("debug:  nil returned.  status of "..name.."="otherdevices[name])
        if (otherdevices[name] == 'On') then
            commandArray[name] = 'Off'
            print(name .. " Dead")
        end
    else
        print("debug: Not nil returned.  status of "..name.."="otherdevices[name])
        if (otherdevices[name] == 'Off') then
            print(name .. " Is a Alive")
            commandArray[name] = 'On'
        end
    end
end

This is all:

Code: Select all

2017-11-23 23:57:00.171 LUA: D.M.: IP Port check

[jvdz]

That isn't possible with the script I posted as that line is commented out on line 3!
Do you have multiple version of the script or double check the update worked.

Jos

[Derik]

sorry did not see the update..
Now this is the update:

Code: Select all

2017-11-24 19:52:00.648 Error: EventSystem: in Port test: [string "commandArray = {} ..."]:12: ')' expected near 'otherdevices'

Just a error

[jvdz]

Understand as I made a typo in the print() debug lines.
This script is tested and working for me on my test domoticz setup:

Code: Select all

commandArray = {}

print ("debug: D.M.: IP Port check")

function update_portalive(name, ip, port)

    -- Windows https://joncraton.org/blog/46/netcat-for-windows/ untested

    s = "nc -z -w 1  " .. ip .." " .. tostring(port)
    print("debug:"..s)
    if (os.execute(s) == nil) then
        print("debug:  nil returned.  status of "..name.."="..otherdevices[name])
        if (otherdevices[name] == 'On') then
            commandArray[name] = 'Off'
            print(name .. " Dead")
        end
    else
        print("debug: Not nil returned.  status of "..name.."="..otherdevices[name])
        if (otherdevices[name] == 'Off') then
            print(name .. " Is a Alive")
            commandArray[name] = 'On'
        end
    end
end

Hope this will work for you too.
