Samba Network Sharing |
Introduction
Most Linux systems are the part of networks that also run Windows systems. Using Linux Samba servers, your Linux and Windows systems can share directories and printers.
Samba is an open-source implementation of the Server Message Block (SMB) and Common Internet File System (CIFS) protocols that provides file and print services between clients across various operating systems
Samba Configuration File:
The default configuration file (/etc/samba/smb.conf) allows users to view their home directories as a Samba share. It also shares all printers configured for the system as Samba shared printers. In other words, you can attach a printer to the system and print to it from the Windows machines on your network.
Samba Server and Samba Client Machine Details
[root@server ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain
::1 localhost localhost.localdomain
192.168.56.101 server.agoutam.com server
192.168.56.102 client.agoutam.com client
192.168.56.101 www.agoutam.com
Where :
Samba Server Run : 192.168.56.101 server.agoutam.com server
Samba Client Run : 192.168.56.102 client.agoutam.com client
Samba Services and Port for Firewall to open In order to Run Samba Service
Ports you need to open for two-way samba communication with Windows and Linux desktop systems.
NetBIOS-ns – 137/tcp # NETBIOS Name Service
netbios-dgm – 138/tcp # NETBIOS Datagram Service
netbios-ssn – 139/tcp # NETBIOS session service
microsoft-ds – 445/tcp # if you are using Active Directory
Port 445 (TCP) – NetBIOS was moved to 445 after 2000 and beyond, (CIFS)
# firewall-cmd --permanent --zone=public --add-service=samba
# firewall-cmd --reload
OR
# firewall-cmd --permanent --add-port=137/tcp
# firewall-cmd --permanent --add-port=138/tcp
# firewall-cmd --permanent --add-port=139/tcp
# firewall-cmd --permanent --add-port=445/tcp
