hosts allow = 192.168.1.
security = user
passdb backend = tdbsam
encrypt passwords = yes
client plaintext auth = no
#-- server signing mandatory : Resolves Security Scanners finding SMB Password Encryption Not Required --#
server signing = mandatory
#-- smb encrypt: Requires Win8/10/Server2012 or newer clients due to smbv3 --#
#smb encrypt = mandatory
path = /path_to_share
valid users = sambauser1, sambauser2
browsable = yes

Config File Help

vim /etc/samba/smb.conf.example

Test the samba share

CIFS Client Setup

  1. Install Packages
    yum install -y cifs-utils samba-client
  2. List remote shares
    smbclient -L <remote-cifs-server>
  3. Create local directory structure to mount the shares in
    mkdir -p /data/shared/<cifs-share-name>
  4. Create root ssh directory if it does not exist
    mkdir /root/.ssh
    chmod 700 /root/.ssh
  5. Create the CIFS credentials file
    touch /root/.ssh/.<cifs-share-name>
    chmod 600 /root/.ssh/.<cifs-share-name>
  6. Edit the credentials file, add share's user/pass/domain
    vim /root/.ssh/.<cifs-share-name>
  7. Create persistent CIFS mount in /etc/fstab
    vim /etc/fstab
    //<remote-cifs-server>/<sharename> /data/shared/<cifs-share-name>  cifs  auto,credentials=/root/.ssh/.<cifs-share-name>,_netdev,uid=<user>,gid=<users>,rw  0 0
  8. Mount the share
    mount -a
