Host Your Own Samba File Server

Motivation

A common problem with running a mixed-environment is sharing files between GNU/Linux and Windows computers. The best way to provide Windows computers access to your GNU/Linux file server is using Samba.

Prerequisites

Install samba server and client packages.

$ sudo apt-get install -y samba smbclient
Configure Samba Server

I configure two shares: one read-only (called data) and one read-write (called data-rw). Append the following to the end of /etc/samba/smb.conf:

[data]
 comment = Data Share (read-only)
 path = /mnt/md0/
 available = yes
 valid users = myuser
 read only = yes
 browseable = yes
 public = yes
 writeable = no
[data-rw]
 comment = Data Share
 path = /mnt/md0/
 available = yes
 valid users = myuser
 read only = no
 browseable = yes
 public = yes
 writeable = yes
Create Samba User

Next, create a new samba user using the following command and it will prompt you to specify a password for the user and then again to confirm the password.

sudo smbpasswd -a myuser
New SMB password:
Retype new SMB password:
Verify the Configuration with testparm

The testparm utility checks the /etc/samba/smb.conf configuration file for internal correctness.

$ testparm
Load smb config files from /etc/samba/smb.conf

Test the Samba Server with smbclient and smbget

smbclient can be used to verify that all the shares are available on the server.

$ smbclient -L euclid

smbget is a wget-like utility for downloading files from a samba share

$ smbget smb://euclid/data/test.txt
