SMB Provide Network Shares Suitable For Group Collaboration
General Information
Samba shares for groups.
Prerequisites
Lab Setup
The following virtual machines will be used:
- server1.example.com (192.168.1.150) → Perform all SMB client tests from here
- server2.example.com (192.168.1.151) → Install the Samba Server here
Group Shares: Server
Create a group
groupadd smbgrp
Add users to the group
usermod -G smbgrp user1 usermod -G smbgrp user2
Create samba passwords
smbpasswd -a user1 smbpasswd -a user2
Setup the group directory for sharing
mkdir /sambashare_group chown :smbgrp /sambashare_group chmod 770 /sambashare_group
SELinux: Set file context
semanage fcontext -at samba_share_t "/sambashare_group(/.*)?" restorecon -Rv /sambashare_group
Create the new directory share config
vim /etc/samba/smb.conf [sambashare_group] comment = My Groups Samba Share path = /sambashare_group valid users = @smbgrp write list = @smbgrp writable = yes force group = +smbgrp create mask = 0770 # Defaults, but listing in case something in [global] over rides browsable = yes public = no
- +smbgrp → The “+” means that only users already in the group (smbgrp) will use that as their primary group when accessing the share.
Restart the service for changes to take effect
systemctl restart smb
Group Shares: Client
Ensure the same users and group exist on the client
- uids and gids must match!
List shares
smbclient -L //192.168.1.200 -U user1
Setup local directory for mounting the remote samba share
mkdir /collaborate
Mount Persistently
vim /root/.sharedcreds username=user1 password=password vim /etc/fstab //192.168.1.200/smbgroupshare /collaborate cifs _netdev,rw,credentials=/root/.sharedcreds,uid=1004,gid=1004 0 0
