Securing unencrypted traffic with stunnel
Stunnel can be used to provide secure encrypted connections for clients or servers that do not speak TLS or SSL natively. In this tutorial we'll secure Samba connection but you could use this for other services like SMTP, IMAP, POP3 etc.
If you are securing a service where the client supports encrypting like SMTP, IMAP and POP3 you can skip the client step.
Server
1. Install stunnel
apt-get install stunnel
Installing and configuring Samba
Samba is a free software re-implementation of SMB/CIFS networking protocol providing file and print services for various Microsoft Windows clients and can integrate with a Windows Server domain, either as a Primary Domain Controller (PDC) or as a domain member. It can also be part of an Active Directory domain.

MySql database replication (master/slave)
In this tutorial we'll create a simple one-way master/slave database replication. You must have at least one master and one slave but you can use multiple slaves.
Master
1. Configure master to listen on all ip addresses (pico /etc/mysql/my.cnf)
#bind-address = 127.0.0.1
Port forwarding with iptables
In this tutorial we'll set up a simple port forwarding (NAT) using iptables.
1. Enable ip forward
echo "1" > /proc/sys/net/ipv4/ip_forward
Installing ntop network monitoring tool
ntop is a network traffic probe that shows the network usage, similar to what the popular top Unix command does. ntop is based on libpcap and it has been written in a portable way in order to virtually run on every Unix platform and on Win32 as well.
ntop users can use a a web browser (e.g. netscape) to navigate through ntop (that acts as a web server) traffic information and get a dump of the network status. In the latter case, ntop can be seen as a simple RMON-like agent with an embedded web interface.
1. Install required packages
apt-get install ntop
