This is a brief post about adding and removing users to and from our NAS after the initial setup. There are lots of websites showing how to add a user to Samba. I just want to point out something that’s worth knowing when testing the setup of the new user.<\/p>\n\n\n

This post is part of a series about building a Network-Attached Storage (NAS) with redundancy using a Raspberry Pi (RPi). See here<\/a> for a list of all posts in this series.<\/p>\n\n\n\n

Adding a User <\/h2>\n\n\n\n

You can add a user with<\/p>\n\n\n\n

sudo adduser --no-create-home --disabled-password --disabled-login username<\/code><\/pre>\n\n\n\n
You’ll be asked to enter some additional information (but you don’t have to). Then the new user will be created and added to group users<\/em>. No home directory and password will be created and the user won’t be able to log in on the RPi (none of that is necessary for a user that should only be able to connect via Samba). Next we add the user to Samba and setup their password with<\/p>\n\n\n\n
sudo smbpasswd -a username<\/code><\/pre>\n\n\n\n
Finally reboot your system for the changes to take effect (or log out and log back in).<\/p>\n\n\n\n
Now that we’ve added the user it seems normal (at least to me) to try to mount a Samba share on our main computer, using the newly created user. The following command (which we’ve been using to mount shares) fails:<\/p>\n\n\n\n
\"\"\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n
That’s because we set the uid<\/em> option to test_user<\/em>, which doesn’t exist on our main system. So to test mounting the share we either add test_user<\/em> to our main system or we run the command<\/p>\n\n\n\n
sudo mount -t cifs \/\/192.168.50.210\/ShareName \/Mount\/Point -o user=test_user<\/code><\/pre>\n\n\n\n
which doesn’t contain the uid<\/em> option. Leaving out uid<\/em> means that we won’t be able to write to the Share but that shouldn’t be an issue if we only want to test if mounting works.<\/p>\n\n\n\n
Removing a User<\/h2>\n\n\n\n
To remove a user we first remove it from Samba with<\/p>\n\n\n\n
sudo smbpasswd -x username<\/code><\/pre>\n\n\n\n
Then we delete it from the system with<\/p>\n\n\n\n
sudo userdel username<\/code><\/pre>\n\n\n\n
Done.<\/p>\n","protected":false},"excerpt":{"rendered":"
