Howto: Adding share in samba server under Linux or UNIX

Q. How do I add share called incoming? This share definitions should be linked up to directory called /home/incoming.
A. You can define a share using samba configuration file itself. Open /etc/samba/smb.conf file and add code snippet as follows:
# vi /etc/samba/smb.conf
Add following code:
[incoming] comment = Icomming data writable = yes path = /home/incoming Save close the file. Restart Samba :
# /etc/init.d/samba restart
If you are using Redhat/CentOS/Fedora core type:
# service smb restart
See also: => A Samba permission howto
=> For more information and samba configuration option read smb.conf man page by typing following command:
man smb.conf
=> Visit official samba web site for more examples and information.
