help adding user to sudoers

[colet]

Hello,

I've read up on visudo and have added the line:
myuser ALL=(ALL) ALL

But myuser still gets the error:
-bash: /usr/bin/sudo: Permission denied

Is there something I should restart? Thanks for any tips.

That line looks fine, and as long as you used visudo to edit /etc/sudoers the changes should have stuck.

You also need to ensure that the binary at /usr/bin/sudo has the correct permissions - by default they are not set correctly for security reasons.

I have permissions of 4111 on /usr/bin/sudo and this seems to work fine - you certainly need to make sure the 'set UID' bit is set (the 4) otherwise things won't work.

As for the /etc/sudoers entry, you might want to try using:

user ALL=(ALL) NOPASSWD: ALL

if you feel brave. I use this for one user, from whose account PHP scripts are run to update content within other accounts. For this reason, I need it to work without having to enter the root password.

Additionally, you probably need to make sure that you're using a normal bash shell for the user and not a jailshell.

But myuser still gets the error:
-bash: /usr/bin/sudo: Permission denied

Sounds like a permission error from sudo itself - check the permissions on the sudo binary.

permissions on sudo

The problem was indeed the permissions on sudo. 4111 did the trick.

Thanks for the help, all.
