Continuing the discussion from Disable internet connection of specific echo device on fritz box via script:

Hi,
I tried to change the userprofile with the command which you discribe. But I always get a arrow in the Log file.
Herer are my source code

rule "echoesszimmeranaus"
when
	Item echoanaus changed
then
	createTimer(now) [|
		if (echoanaus.state == OFF) {
			executeCommandLine("/etc/openhab2/scripts/fritzboxprofile.sh 192.168.178.1 password filtprof1071 never", 5000)
		} else {
			executeCommandLine("/etc/openhab2/scripts/fritzboxprofile.sh 192.168.178.1 password filtprof1071 unlimited", 5000)
		}
	]
end

#!/bin/sh

challenge=$(curl -s "http://$1/login_sid.lua?username=admin" | grep -Po '(?<=<Challenge>).*?(?=</Challenge>)')
md5=$(echo -n ${challenge}"-"$2 | iconv -f ISO8859-1 -t UTF-16LE | md5sum -b | awk '{print substr($0,1,32)}') 
response="${challenge}-${md5}"
sid=$(curl -i -s -k -d "response=${response}&username=admin" "http://$1" | grep -Po -m 1 '(?<=sid=)[a-f\d]+' | tail -1)

curl -d "sid=${sid}&edit=$3&time=$4&budget=unlimited&apply=&page=kids_profileedit" "http://$1/data.lua" >/dev/null 2>&1

For the username I tried also a second which has admin rights.

This is the warning message at the log

[WARN ] [lipse.smarthome.io.net.exec.ExecUtil] - Execution failed (Exit value: -559038737. Caused by java.io.IOException: Cannot run program "/etc/openhab2/scripts/fritzboxprofile.sh" (in directory "."): error=13, Permission denied)

Maybe anybody can help me?

Best Regards

ExecuteCommandLine syntax varies by openHAB version, so let’s clear that up first.

3

Do you get this message in case you add

cd /tmp

between "#/bin/sh and the row that starts with “challenge=” ?

Hi,

did you check the owner and the permission of the file “fritzboxprofile.sh”? You can run “ls -l” in the directory of the file and post the output.

I had add sudo in the commando line

executeCommandLine("sudo /etc/openhab2/scripts/fritzboxprofile.sh  password filtprof1071 never", 5000)

So I haven’t an Error on the Log but the userrights aren’t changing in the Fritzbox.
I had made a special user in Fritzbox for chaging the userright. I hope this is correct

Still applies

You can also check for responses

var results = executeCommandLine( ... blah ... )
logInof ("test", "My exec returned " + results)

It looks like that the EXEC Binding isn’t installed.

Off sudo: /etc/openhab2/scripts/fritzboxprofile.sh: command not found
I use openhabe 2.5 and I can't install the EXEC Binding over Paper UI. Is there an additional way to install it

Sorry I thought that the Binding is installed. I Tried it and I didn't receive an error message in Log

Format Error
Herr is the code again, Sorry

Off sudo: /etc/openhab2/scripts/fritzboxprofile.sh: command not found

  • executeCommandLine is an action
  • exec binding is a binding that needs to be installed
  • executeCommandLine is not part of the exec binding
  • according to your code snippets you use executeCommandLine which does not require the exec binding to be installed
  • command not found means that a file / binary or shell script that is to be executed cannot be found
  • as the shell script ( fritzboxprofile.sh ) is before the colon this should mean that your shell script is started to be executed but a command from inside of that shell script is not found
  • you can use a PATH variable inside of the script and add all relevant directories to that environment variable
  • alternatively you may always use full path to any executeable/script/command
  • add debug output to your script that ‘every’ line creates output once the error message appears you should be able to identify which command is the root cause ( because you can see the debug output of the line before )

At first thank you for helping

I found the problem. The userrights are rong. The had only read and writte access.

No I have the next problem. It’s still not changing the user in then fritzbaox. But I no error occur.
How can I debugg the script?

11

You can add addtional rows to the script like:

echo $challenge > /tmp/debug.txt
echo $md5 >> /tmp/debug.txt
echo $sid >> /tmp/debug.txt

they need to be added after the related variable is set.
Output will be stored in directory /tmp in file debug.txt.

To see result of the last curl command

>/dev/null

can be replaced with

>>/tmp/debug.txt

Pay attention to > versus >>. The first one creates/overwrites a file. The second one appends output to the end of the file.

I found the problem.
A slash was missing in the fritzprofile.sh :wink:
Thank you very much for helping me
