According to the samba.org website: ''"Samba is the standard Windows interoperability suite of programs for Linux and Unix. Samba is Free Software licensed under the GNU General Public License, the Samba project is a member of the Software Freedom Conservancy."'' Although a Samba server can provide many features such as printer sharing and backups, this This lab's primary focus is to set up a Samba server on a Linux server in order to allow MS Windows users to share common files from the Linux's Samba server.

# Use the Windows machine you are already running Vmware on. If you have a Linux host - good for you, you can either use a Windows VM or skip this part.# Add the prerouting and forwarding rules to your host's iptables necessary to redirect samba traffic from outside your network to your VM2, making sure to replace the X with your own network address.::<code>iptables -I FORWARD -p tcp --dport 139 -d 192.168.X.3 -j ACCEPT</code>::<code>iptables -I FORWARD -p tcp --dport 445 -d 192.168.X.3 -j ACCEPT</code>::<code>iptables -t nat -A PREROUTING -p tcp --dport 139 -j DNAT --to-destination 192.168.X.3</code>::<code>iptables -t nat -A PREROUTING -p tcp --dport 445 -j DNAT --to-destination 192.168.X.3</code>OR with specifing the interface (whichever works):::<code>iptables -t nat -A PREROUTING -i *externalinterface* -p tcp --dport 139 -j DNAT --to-destination 192.168.X.3</code>::<code>iptables -t nat -A PREROUTING -i *externalinterface* -p tcp --dport 445 -j DNAT --to-destination 192.168.X.3</code>where *externalinterface* is an interface name (e.g. ens33)<br>'''NOTE:''' when you restart libvirtd, it will move your FORWARD rules to the end of the chain, invalidating them.# Modify the '''hosts allow ''' setting on your '''vm2''' to also accept connections from the windows machine you are using.

{{Admon/important |Backup your VMs!|You MUST perform a '''full backup''' of ALL of your VMs whenever you complete your '''OPS335 labs''' or when working on your '''OPS335 assignments'''. You should be using the dump or rsync command, and you should use the Bash shell script that you were adviced to create in order to backup all of your VMs.}}
