Configuring port forwarding with rinetd
inetd redirects TCP connections from one IP address and port to another. rinetd is a single-process server which handles any number of connections to the address/port pairs specified in the file /etc/rinetd.conf. Since rinetd runs as a single process using nonblocking I/O, it is able to redirect a large number of connections without a severe impact on the machine. This makes it practical to run TCP services on machines inside an IP masquerading firewall.
1. Install rinetd
apt-get install rinetd
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
Add an additional IP address to your server
1. Open the network configuration file (pico /etc/network/interfaces)
Check the name of your network interface. You should see a line similar to this one: "iface eth0 inet static". In my case the name is eth0.
Add these lines to the end of the file:
auto eth0:1
iface eth0:1 inet static
address 192.168.1.3
netmask 255.255.255.0
broadcast 192.168.1.255
network 192.168.1.0
