Samba

Samba - allows Linux to transfer files with Windows clients

• http://www.krizna.com/ubuntu/setup-file-server-ubuntu-14-04-samba/ (Anonymous share and Secured share via username/password)
• Samba doesn't use the system account password, we need to set up a Samba password for our user account
• It is fine to use an existing directory to share

sudo apt-get install -y samba samba-common python-glade2 system-config-samba
sudo cp -pf /etc/samba/smb.conf /etc/samba/smb.conf.bak
sudo sh -c 'cat /dev/null  > /etc/samba/smb.conf'
sudo nano /etc/samba/smb.conf
sudo service smbd restart
testparm
# password protected
sudo addgroup smbgrp
sudo useradd till -G smbgrp
sudo smbpasswd -a SOMEEXISTEDUSER
sudo mkdir -p /samba/secured
cd /samba
sudo chmod -R 0770 secured
sudo chown root:smbgrp secured
sudo nano /etc/samba/smb.conf
sudo service smbd restart 
testparm

sudo netstat -pant | grep smbd   # mine shows 139 & 445

• I have trouble to connect to the samba server though connecting it itself from the samba server works fine.

$ smbclient -L //192.168.1.XX/sambashare -U SOMEEXISTEDUSER
WARNING: The "syslog" option is deprecated
Connection to 192.168.1.XX failed (Error NT_STATUS_IO_TIMEOUT)

# From server itself
$ smbclient -L //localhost 

# Solution: ufw
# https://askubuntu.com/a/184806
sudo ufw allow Samba

# From the client 
$ smbclient -L //192.168.1.XX/sambashare -U YYY
# No error. Return to the local prompt again.
# Now we can use Ubuntu's Files app to connect to the server
# smb://192.168.1.XX/

• What Ports Need To Be Open For Samba To Communicate With Other Windows/Linux Systems?
• Symbolic link files. Not working from my test
• Share 'between' ubuntu and Windows
• Start and stop the samba daemons

$ ps -ef | grep smbd    # see if the Samba daemon (smbd)
$ ps -ef | grep nmbd    # see if the NetBIOS name server daemon (nmbd) is running

$ sudo service smbd stop  # does not stop nmbd 
$ sudo service nmbd stop

$ sudo service smbd start
$ sudo service nmbd start

• smb.conf — The configuration file for the Samba suite

sudo apt-get install samba samba-common
sudo apt-get install python-glade2
sudo apt-get install system-config-samba

Use Dash and search for 'samba'. It will ask for the user's password first. The samba password can also be set by

sudo smbpasswd -a USERNAME

A non-gui way to configuration samba is adding the following to the end of /etc/samba/smb.conf file, sudo nano -w /etc/samba/smb.conf (-w means no-wrap). Any line beginning with a semicolon (“;”) or a hash (“#”) character is ignored.

[brb]
        path = /home/brb
;       writeable = no
;       browseable = yes
        guest ok = yes

• Share between ubuntu and linux On the client file manager, type smb://192.168.1.XX/
• https://help.ubuntu.com/community/Samba

On Windows PC, go to start and open 'Run' then enter ip with double backslash. Like this (\\192.168.1.XX).
