Setting up SAMBA server

• Accessing samba share
• smbclient -L //localhost
• smbclient -U erick //localhost/data
• Mounting samba share
• yum -y install cifs-utils
• mount -o username=erick //localhost/share /mnt

• Installation
• yum -y install samba samba-client
• systemctl start smb nmb
• systemctl enable smb nmb
• firewall-cmd --permanent --add-service=samba
• firewall-cmd --reload

• Creating share with read access from specific user, changing workgroup and allowing specific network.
• Create linux and samba user <-- linux user should exist first, before creating samba user.
• useradd -s /sbin/nologin erick
• smbpasswd -a erick
• mkdir /sambashare
• semanage fcontext -a -t samba_share_t "/sambashare(/.*)?"
• restorecon -R -v /sambashare
• setfacl -m u:erick:r-X /sambashare
• getfacl /sambashare
• vim /etc/samba/smb.conf
