driving me mental, remote login to pfsense CLI to shutdown
-
Hi All,
Im trying to do a remote ssh into pfsense CLI to shutdown the machine. I added a key to allow a user to login, but when I issue the shutdown -h now, it says permission denied.
I want to do this without using a password so that my parents can shut down this machine using a button in a home automation tool instead of going into the web UI and shutting down, which is painful.
thanks
-
@automate Probably need to install the "sudo" package from package manager if it is not already installed and then issue the command 'sudo shutdown -h now'. I think this works for most variants of Linux, not sure about FreeBSD.
Also you may or may not need the '-h' in the command.
-
thanks same issue :(
i can login with 'ssh user@192.168.1.254' but when i put
ssh user@192.168.1.254 'sudo shutdown -h now'
It fails with:
ssh nsautomate@192.168.1.254 sudo shutdown -h now
We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:#1) Respect the privacy of others. #2) Think before you type. #3) With great power comes great responsibility.sudo: no tty present and no askpass program specified
-
Or this works, but asks me for a password!
ssh -t nsautomate@192.168.1.254 "sudo shutdown -h now"
-
Have you configured sudo correctly?
Does it work if you manually ssh into pfSense and then run the command?
Steve
-
see your other thread... Where you said jimp instructions don't work ;)
-
Aha, so not configured correctly!
-
Reinstalled the package and now I can execute the shutdown script without a password.
I still cannot login via ssh without a password, despite using the ssh-keygen utility and a copy of the key over. it works for a few minutes then stops working. Very bizzare!
-
I always login via public key when I ssh.. Not a fan of passwords and ssh - have had zero issue doing this on any pfsense going back to like 1 ;)
Your saying it lets you log in with public key, and then you go to login again and it doesn't? Do a ssh -vvv when you attempt to login.. what do you get? Or what does the pfsense log say about it after you can not login.
-
LOTS of output hahah!

scratching head
Im not sure what im doing wrong. Can you point me to some kind of tutorial john to do that? I was under the impression i was
-
If your environment doesn't auto find the key to send, then you would have to call it out in your cmd line for ssh.
btw: you don't need to send that direct command, you can just run /etc/rc.halt
-
I followed this:
https://www.tecmint.com/ssh-passwordless-login-using-ssh-keygen-in-5-easy-steps/
-
Yeah those guides tell you how to set it up, no need for me to even read it - but your ssh client has to know where the key it is to use.. See how it pulls my key from my home dir..
Setup your local environment to use the key(s) you want.. Be it windows or linux... Im running openssh client on windows..
There is a .ssh dir in c:\users\username - this is where you keys would normally go
-
Thats not going to work.
This is a non interactive setup, what happens is my linux machine (with openhab) runs a script which executes this command as the 'nsautomate' user.
Theres no ability for me to specify keys etc, because its not occuring like that.
What im doing right now is simply 'testing' the command via a shell, but the end state is the openhab user will run this command
-
Well its going to have to be able to send the key, or how would it possible to auth..
-
i thought the keys were saved using the link i mentioned above to the local and remote machine, so when it logs in, its there. That was the whole point.
I used the ssh copy etc
-
I think you should research how public key auths.. Yes there is part on the server that you saved on pfsense, but the client has to send the other part to actually auth.
Running this on linux you can call out in the path directly or the envirnoment of the user running ssh would have it in their path.. You can see when you ran the script where it looked for the key.. Place your private side there.
when you ran the cmd it was looking here for keys it could send
Trying private key: /var/lib/openhab2yeah when you created the keys, sure you saved it somewhere - but it has to be specified where it is and its name in the cmd you run, or the enviornment of the system needs to know where to find it, ie your /var/lib/openhab2 dir is where it was looking for the keys it could send because you didn't call it out in the cmd.
-i would call out path/file to use to auth with from the cmd line with ssh
-
@johnpoz OK, so i copied the key to that directory and the same issue persists.
-
And your sending the key - what does -vvv show you for the process
-
After the copy...

So how could you auth??

I copied as you mentioned, it shows id_rsa.pub under the folder it was looking for and theres a key in there.

Oh it did send something.

Give me a sec to digest
-
of course it didnt. You need to be a brain surgeon with a degree in rocket science to get this sh1t working. Seriously wheres the nearest cliff so I can throw myself and the machine off it!
-
No you don't need to be a brain surgeon... This pretty basic stuff ;)
RSA - yeah prob no longer even accepted.. that guide is from what 2015...
-
Well its taken me 12hrs and I cant get it working, so its not really basic at all.
Im outta ideas, thanks anyway john -
Public key auth is pretty freaking basic stuff.. But yes you have to understand how it works ;)
Just randomly following some guide from 4 years ago, prob going to have issues.
It doesn't like your OLD sha2 sig for one thing, and there were some known bugs with that for sure
https://bugzilla.mindrot.org/show_bug.cgi?id=2799I would create some current stuff, and redo it... You know say ed25519
If you want I have ubuntu could show you the commands to create current stuff ;)

@johnpoz Hello, i did exactly what you've posted. I copied the key to the folder as below:
sudo cp /home/nsautomate/.ssh/id_ed25519.pub /var/lib/openhab2 & to .ssh folderAnd updated the user in the Gui with the new key value.
Still doesnt work, wants a password

Load key "/var/lib/openhab2/.ssh/id_ed25519": Permission denied -
What are the permissions on the file? Why are you trying to use a different user and then another user to auth with?
-
The linux server has software on it called openhab. That software executes its scripts, or rules, using the openhab user. This is a home automation package.
So, the openhab user executes the command but logs in with 'nsautomate'
nsautomate@ihp:~$ sudo ls -la /var/lib/openhab2/.ssh/id_ed25519 -rw------- 1 root root 411 Aug 5 10:39 /var/lib/openhab2/.ssh/id_ed25519 nsautomate@ihp:~$ -
that seems pointless.. if the user account openhab is going to run the command, just create that user on pfsense and use it to auth with and run the halt cmd.
Only root can access that file, per the permissions on it.
-
Cool, that appears to have worked. However, its shut down pfsense but not powered off the unit, like it does if you select 'halt' from the GUI. I can still ping it but not SSH to it and its still forwarding packets despite a CLI message saying its being shut down??
Is there an alternate command that shuts the whole system down gracefully?
-
What kind of hardware?
You probably want
shutdown -p nowhttps://www.freebsd.org/cgi/man.cgi?query=shutdown&manpath=FreeBSD+11.2-RELEASE
-
He has something running on linux that he wants to ssh into pfsense using public key auth and run the rc.halt
Which works just fine I have tested your old thread, on a VM running 2.4.4p3 - takes all of 30 seconds to setup.
He is having a problem using public key auth in general.
-
Sounds like he got it working but didn't get a power off.
/etc/rc.haltis probably a better option.
