sudo works as root, not as user

[mweinmann]

Why is this?


This is ssh'd into freenas base, not a jail.

Sudo as root works, i get sudo 'help' output as expected.
sudo as a user gives me:

sudo: error in /etc/sudo.conf, line 0 while loading plugin `sudoers_policy'
sudo: unable to load /usr/local/libexec/sudo/sudoers.so: (null)
sudo: fatal error, unable to load plugins​

I tried making the sudo libraries all read only, fully, no change. I'm not really sure what is going on.. There was no /etc/sudo.conf file. I did a touch sudo.conf to add and tried, no luck. sudo.conf exists at /usr/local/etc/sudo.conf.

What exactly are you trying to accomplish?

 

[DifferentStrokes]

Root is already the super user. So, root doesn't have to sudo. Look at the user in the Web GUI that you are trying to sudo with and see if that user is a sudoer.

 

[mweinmann]

The user is checked to allow sudo. I just want to be able to sudo from a non root account. I don't get it.

This is a wider problem. other programs, run as user mode, throwing missing shared objects - is there some way to rebuild library links

 

[INCSlayer]

what programs are you running and why are you running them from the base system and not from inside a jail?

 

[SweetAndLow]

You have been mucking with the base system. You shouldn't do this because you will break everything and it's not meant to be modified. You should backup your configuration and do a factory reset. This will fix all the files you changed.

Freenas is an appliance.

Do not modify the base system, it is as simple as that.

I can see absolutely no reason to have a regular user able to run sudo on the base system. Use the jails, that is why they exist.

I didn't change anything until the problems began. I thought basic Unix preference was to login as user and sudo root commands regardless of Unix. Why is there a sudo option in the gui if that is not even recommended and you scold those that use it?

What do you need to do in the cli as sudo?

 

[mweinmann]

Usually just jls and jexec. I was going through an exercise to change my behavior to login to base and jails as user and sudo from there. When I was testing it on base ran into errors. I will try the reset. It's been installed and upgraded for some time.

I don't see any reason to use sudo on freenas.

 

[mweinmann]

But that being said should it throw shared object errors?

No. It just sounds like you have an install that is in an inconsistent state.

 

[mweinmann]

I would agree. Will see what a reset does.

Thanks all!

This is one of the most obvious (to me) differences between Linux and Unix. Linux seems to be much more wary of direct use of the root account than Unix.

The thing is, once you're logged into the FreeNAS GUI, you have root-level access to everything anyway, so there's no point in using sudo in the GUI shell. It's different if you want to give various users SSH access.

 

[Jailer]

Log in via ssh as your user and then type su and enter the root password to switch to root. Then you will be able to switch to the jails (jexec) and do what you need to do as root without using sudo. No need to make it any harder than necessary.

What are you running for hardware?

 

[mweinmann]

I always login ssh. As user typing su gives error. I know how to use just didn't get why an error as user but not root. Plan to do reset soon to resolve

This morning I installed a fresh version of freenas onto a new usb flash drive. I imported my backup and it's restored perfectly. The user-mode sudo error is gone.

I'm quite impressed how perfectly and easily the config was restored, imported volumes, etc.

Great job!
