openHAB 2.x.x backup script
#########################################
Please run this script as root! (e.g. use sudo)
openhab@openhab2:/lib/systemd/system$
After adding the home/kris switch to the command and moving it above as suggested by Rich, it now works! Thank you guys
here is mine,
Cmnd_Alias BACKUP = /usr/bin/openhab-cli backup /home/kris/OH2Backup.zip
openhab ALL=(ALL) NOPASSWD: /etc/openhab2/scripts/backup.sh, BACKUP
Sure, you have to use sudo:
openhab@openhab2:/lib/systemd/system$ sudo openhab-cli backup /home/kris/OH2Backup.zip
^^^^
The setting āNOPASSWDā in sudoers is to enable the user openhab to use the command āsudoā without password for a specific command, but you always have to call sudo.
Spoke too soon thats shown in the openhab console.
if i run the command in the rule , from the CLI it works just fine
sudo -u openhab sudo openhab-cli backup /home/kris/OH2Backup.zip
05:21:14.425 [INFO ] [.smarthome.model.script.Server Backup] - Backup Executed Sorry, user openhab is not allowed to execute '/usr/bin/sudo /etc/openhab2/scripts/backup.sh' as openhab on openhab2.ddns.net.
You donāt need to use sudo -u openhab in a rule, just use
sudo openhab-cli backup /home/kris/OH2Backup.zip
Again, works via CLI butnot the rule
05:32:59.112 [INFO ] [.smarthome.model.script.Server Backup] - Backup Executed Sorry, user openhab is not allowed to execute '/usr/bin/sudo /etc/openhab2/scripts/backup.sh' as openhab on openhab2.ddns.net.
rule "Backup OH2 ready for RClone, in the proceeding rule"
when
Time cron "0 0 1 ? * * *"
then
logInfo("Server Backup", "OH2 is being backed up")
executeCommandLine("sudo openhab-cli backup /home/kris/OH2Backup.zip")
end
I have the following commands:
Thing exec:command:openHabRestart [command="sudo systemctl restart openhab2.service", interval=0, autorun=false]
Thing exec:command:openHabBackup [command="sudo openhab-cli backup /var/lib/openhab2/backups/backup.zip", interval=0, autorun=false]
wich work fine when I add this line to sudoers:
openhab ALL=(ALL) NOPASSWD: ALL
But I donāt know how ādangerousā this could be in fact of an internet attac or something else. I donāt understand how I can give the user āopenhabā permission to only run these commands. Can you please help me?
Thank you!
Yes, this is posiibly dangerous. Better set the correct command, see
I hesitate to open a new topic but itās exactly the same topic and i have almost tried everything in this thread
the openhab service getting restarted without reason

Any ideas?
Hi all,
I know this is old topic but it is very related to what I am trying to do.
I am trying to restart service that is running on the same rPi 4 as the openhabian but I canāt doesnāt work.
I created file in the etc/sudoers.d containing the following:
openhab ALL=(ALL) NOPASSWD: /bin/systemctl start ring
openhab ALL=(ALL) NOPASSWD: /bin/systemctl restart ring
openhab ALL=(ALL) NOPASSWD: /bin/systemctl status ring
I did try to execute the commands as openHab user via the ssh connection and it works fine:
I do not get any prompts for password when I execute the commands defined in the openhab sudoers file via ssh connection. The commands execute correctly:
[01:07:07] openhab@openHABianDevice:/etc/sudoers.d$ sudo systemctl restart ring
[01:20:33] openhab@openHABianDevice:/etc/sudoers.d$ sudo /usr/bin/systemctl status ring

I configured the exec binding as follows (I tried different variations of the commands with or without the path /bin/ or /usr/bin/ before sudo and systemctl). All the commands were whitelisted:
Thing exec:execRingStart:remote-send [
command="sudo systemctl restart ring",
interval=0,
autorun=true]
Thing exec:execRingStatus:remote-send [
command="sudo systemctl status ring",
interval=0,
autorun=true]
My rules are as follows:
rule "ring:Service restart"
when
Item itmRingHeartbeatON received update OFF or
Time cron "0 0/5 * 1/1 * ? *" // Test every 5 minutes
then
//if (itmRingHeartbeatON.state != ON) {
Ring_Remote_Send.sendCommand(ON)
logInfo("FILE","ring:Service restart| Restart ring service")
Thread::sleep(3000)
logInfo("FILE","ring:Service restart| Result :" + Ring_Remote_Send_Out.state)
Ring_STSRemote_Send.sendCommand(ON)
Thread::sleep(3000)
logInfo("FILE","ring:Service restart| Result :" + Ring_STSRemote_Send_Out.state)
// }
end
rule "ring:Service restart2"
when
Item TestSwitch received update ON
then
val results = executeCommandLine("/bin/sudo /bin/systemctl restart ring")
logInfo("Test", results)
end
When I execute the first rule nothing happens (I donāt see any errors in the log, but also the service is not restarted)

Any ideas?
Thanks
Itās generally better to start a new thread (including all of the information thatās requested in the template) and reference any old threads that may be relevant. There are many threads that are relevant to what you want to do, but Iāll point you to the tutorial I wrote for OH2.
executeCommandLine is part of the core, so if you just want to send a shell command then you donāt actually need the Exec Binding. You just need your second rule.
Iām guessing that youāre on OH3, in which case you arenāt using the proper syntax. Itās one of a few breaking changes that you need to keep in mind when looking at old discussions that were written for OH2.
Thanks @rpwong,
You are right, I am on OH3 so, putting the quotes solved the problem with my 2nd rule
val results = executeCommandLine("sudo", "systemctl", "restart", "ring")
Good stuff.
No oneās going to mind if you start a new thread and link to an old one you think might be useful, but when you revive an old thread youāll find that people are less likely to jump in since they donāt want to read the whole thing. Luckily, I was able to guess that youāre on OH3 and quickly spot the problem. 
Thanks, will do so the next time
Hi all!
I canāt solve my āsudoā problem even though Iāve been trying for many hours. I am using openHAB 2.5.11-1
I use the following Exec Binding Definition in my things file:
Thing exec: command: ipc_ns_read [command = "perl /opt/TM/x.pl",transform="REGEX((.*?))", Interval = 3, timeout = 5, autorun = true]
It works great! Now Iām trying to use āsudoā in my command because Iāll need that later.
Thing exec: command: ipc_ns_read [command = "sudo perl /opt/TM/x.pl",transform="REGEX((.*?))", Interval = 3, timeout = 5, autorun = true]
The return value of the item is:
"We trust you have received the usual lecture from the local System ........ etc."
Calling the script from the command line as user openhabian works without any problems:
openhabian @ openHABianDevice: ~ $ sudo perl /opt/TM/x.pl
The following line is entered in /etc/sudoers.d/openhabian:
openhabian ALL = (ALL: ALL) NOPASSWD: ALL
I donāt understand why it works from the shell command line and not in the exec binding. Does anyone have a helpful idea?
Thanks Tom
Perhaps itās not running under user openhabian. The end of the ālectureā message will tell you.
Thanks for your response!
The end of the lecture is sudo: no tty present and no askpass program specified
I do not understand what this means about the running user.
If I create a new file in my script it is created under the user āopenhabianā
Oh yes, thatās less helpful than I imagined.
You logged into the console is not necessarily the same user that the openhab service is running under.
Oh! Can you help me to find out which user the openhab service is running?
I thought the user who created a file is the right one.
Thanks, Tom
No, I donāt know *nix systems.
If you look further up the thread you joined, youāll see that āopenhabā would be a good guess.
