ntop 1.0
ntop is a tool that shows the network usage, similar to what the popular
top Unix command does. ntop can be used in both interactive or web mode.
In the first case, ntop displays the network status on the user's
terminal whereas in web mode a web browser (e.g. netscape) can attach to
ntop (that acts as a web server) 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. 

ntop's main features include: 

1. Sort network traffic according to many protocols 
  1.TCP 
  2.UDP 
  3.ICMP 
  4.IPX 
  5.Decnet 
  6.AppleTalk 
  7.FTP 
  8.HTTP-IC (Internet Cache a.k.a. squid) 
  9.DNS 
  10.Telnet 
  11.Netbios (including Netbios-over-IP) 
  12.POP 
  13.SNMP 
  14.NFS 
  15.X11 
  16.DLC 
  17.RARP/ARP 
2. Show network traffic sorted according to various criteria 
3. Display traffic statistics 
4. Show IP traffic distribution among the various protocols 
5. Analyse IP traffic and sort it according to the source/destination 
6. Display IP Traffic Subnet matrix (who's talking to who?) 
7. Report IP protocol usage sorted by protocol type 

ntop is based on libpcap and it has been written in a portable way in
order to virtually run on every Unix platform. ntop is available both in
source and binary (Linux, IRIX, Solaris, BSD, HP-UX) format. 

Summary of changes (v.0.4 vs. v.1.0): 
1. Added support for non-IP protocols 
2. Added support for various IP protocols such as SNMP/FTP/HTTP and many
others 
3. Added a log capability similar to the one offered by tcpdump 
4. Added TCP/UDP session tracking 
5. Added IP traffic distribution statistics according to
protocol/source/destination 
6. Added subnet traffic matrix (who's talking to who) 
7. AddedIP subnet protocol report (what IP protocols are used by hosts
that belog to the local subnet) 
8. Improved web interface usability 
9. Added support for various Unix platforms including various Linux
flavours 
10.Added some binary distributions (Linux RedHat/Debian, Solaris) 


ntop is available in three formats: 
1. source (it should compile virtually on any Unix platform) 
2. binary 
   * Linux ELF 
   * IRIX 6.2 
   * Solaris 2.6 
   * HP-UX 10.X 
   * FreeBSD 2.2.6 
3. binary package 
   * Linux: Debian and RedHat 
   * Solaris SPARC
