About this Hands-on Lab

Understanding a service well enough to troubleshoot it is an essential skill as a System Administrator. In this lab, we’ll go over troubleshooting a SAMBA installation.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Ensure the user is added to Samba correctly
pdbedit -L

Shows us that there are no Samba users on the system.

smbpasswd -a pinehead

Fails because there is no pinehead user on the system.

useradd pinehead
smbpasswd -a pinehead
pdbedit -L

Now we have a Samba user named pinehead. Re-running the mount command works.

Ensure the mount is writable.
  1. First, we need to add the following line to /etc/samba/smb.conf:
    read only = no
  2. Additionally, we need to run these commands to make sure the /opt directory (specified in the smb.conf file) is eligible for writing by pinehead through Samba.
chgrp pinehead /opt
chmod g+w /opt
chcon -t samba_share_t /opt

Once those are done, we can run systemctl restart smb and try to touch /mnt/test. It should work perfectly!

Additional Resources

A Junior admin has come to you with a problem that he ran into while setting up a Samba server. He tried to mount the LAmount volume locally (as a test) using the command mount -t cifs -o username=pinehead,password=1234 //localhost/LAmount /mnt but he keeps getting permission denied errors.

Your task is to make sure that the mount command works, and that the resulting mount point is writable.
