Setup Samba Server Under Ubuntu

Objective

1. Set up Samba file sharing for Linux, Windows, Tablet
2. Allow access of specified resources without login under the same LAN
3. Allow login access of restricted resources under the same LAN

Install Steps

1. install Samba:

         sudo apt-get install samba

         sudo smbd start

        sudo ufw disable

2. configure /etc/samba/smb.conf:

sample file setup:

  [global]

    workgroup = workgroup

    server string = %h server (Samba, Ubuntu)

    security = user

    passdb backend = tdbsam

    cups options = raw

    map to guest = Bad User

    guest ok = yes

[homes]

comment = Home Directories

path = /home/user/Documents

valid users = %S

read only = No

create mask = 0755

browseable = No

[public]

comment = tmp directory

path = /home/public

read only = No

note that if public path is under /home/user, it doesn't work.

3. test:

  testparm

4. add user:

  sudo smbpasswd -a user

5. restart samba:

    sudo /etc/init.d/samba restart

View Shares

Suppose the Samba server IP address is 192.168.0.18

1. under Linux file manager:

smb://192.168.0.18/      --- to access public share
or
smb://192.168.0.18/user    --- to access restricted share

2. under Windows:
//192.168.0.18/      --- to access public share
or
//192.168.0.18/user    --- to access restricted share

3. under tablet:
install EZ file manager

Setup MFC-7345N Scanner

I have a MFC-7345N 3-in-1 printer/scanner/fax, which was initially setup with a IP address of 192.96.96.199. Later on the IP address was changed to 192.168.0.199. The PC machines adapt to the change easily, but Ubuntu machines got stuck.
Here's how I re-setup my MFC-7345N scanner under Ubuntu.

• check if the system is 32bit or 64bit: uname -a
• download brscan3-0.2.11-5.amd64.deb and brscan-skey-0.2.4-1.amd64.deb
• install package: sudo dpkg -i --force-all brscan3-0.2.11-5.amd64.deb brscan-skey-0.2.4-1.amd64.deb
• check if the scanner model is supported, if not, choose a closer one:  brsaneconfig3 -q
• configure the scanner: sudo brsaneconfig3 -a name=SCANNER model=MFC-7440N ip=192.168.0.199
• check setup: brscan-skey -l
• use gscan2pdf to scan
