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.<\/p>\n

ntop users can use a a web browser (e.g. firefox) 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. The use of:<\/p>\n

* a web interface
\n * limited configuration and administration via the web interface
\n * reduced CPU and memory usage (they vary according to network size and traffic) <\/p>\n

make ntop easy to use and suitable for monitoring various kind of networks. <\/p>\n

To install ntop on ubuntu;<\/p>\n


\nsudo aptitude install ntop
\n<\/code><\/p>\n

To start the ntop service
\n
\nsudo \/etc\/init.d\/ntop start
\n<\/code><\/p>\n

To check the ntop service
\n
\nps aux | grep ntop
\nntop 18613 2.2 2.8 156940 28908 ? Ssl 21:40 0:00 \/usr\/sbin\/ntop -d -L -u ntop -P \/var\/lib\/ntop --access-log-file \/var\/log\/ntop\/access.log -i eth0 -p \/etc\/ntop\/protocol.list -O \/var\/log\/ntop
\n<\/code><\/p>\n

To access the web interface please open your web browser application and go to url : http:\/\/localhost:3000<\/p>\n

To install ntop from source;
\nwget http:\/\/downloads.sourceforge.net\/project\/ntop\/ntop\/ntop-3.4-pre2\/ntop-3.4-pre2.tar.gz?use_mirror=cdnetworks-us-2
\ncd ntop
\n.\/autogen.sh
\nmake
\nmake install <\/p>\n

What ntop can do for me?<\/p>\n

* Sort network traffic according to many protocols
\n * Show network traffic sorted according to various criteria
\n * Display traffic statistics
\n * Store on disk persistent traffic statistics in RRD format
\n * Identify the indentity (e.g. email address) of computer users
\n * Passively (i.e. withou sending probe packets) identify the host OS
\n * Show IP traffic distribution among the various protocols
\n * Analyse IP traffic and sort it according to the source\/destination
\n * Display IP Traffic Subnet matrix (who’s talking to who?)
\n * Report IP protocol usage sorted by protocol type
\n * Act as a NetFlow\/sFlow collector for flows generated by routers (e.g. Cisco and Juniper) or switches (e.g. Foundry Networks)
\n * Produce RMON-like network traffic statistics <\/p>\n

Platforms \t<\/p>\n

* Unix (including Linux, *BSD, Solaris, and MacOSX)
\n * Win32 (Win95 and above including Vista) <\/p>\n

Media \t<\/p>\n

* Loopback
\n * Ethernet (including 802.11Q)
\n * Token Ring
\n * PPP\/PPPoE
\n * Raw IP
\n * FDDI
\n * FibreChannel
\n * …and many more <\/p>\n

Requirements \t<\/p>\n

* Memory Usage
\n It depends on the ntop configuration, number of hosts, and number of active TCP sessions. In general it ranges from a few MB (little LAN) to 100 MB for a WAN.
\n * CPU Usage
\n It depends on the ntop configuration, and traffic conditions. On a modern PC and large LAN, it is less than 10% of overall CPU load. <\/p>\n

Protocols \t<\/p>\n

* IPv4\/IPv6
\n * IPX
\n * DecNet
\n * AppleTalk
\n * Netbios
\n * OSI
\n * DLC
\n * …and many more <\/p>\n

IP Protocols \tFully User Configurable
\nAdditional
\nFeatures \t<\/p>\n

* VoIP support (SIP, Cisco SCCP and Asterisk IAX)
\n * NetFlow (including v5 and v9) and IPFIX support
\n * Network Flows
\n * Local Traffic Analysis
\n * Multithread and MP (MultiProcessor) support on both Unix and Win32
\n * Perl\/PHP\/Python lightweight API for accessing ntop from remote
\n * Support of both NetFlow andsFlow as flow collector. ntop can collect simultaneously from multiple probes.
\n * Traffic statistics are saved into RRD databases for long-run traffic analysis.
\n * Internet Domain, AS (Autonomous Systems), VLAN (Virtual LAN) Statistics
\n * Network assets discovery and categorization according to their OS and users
\n * Protocol decoders for most of known P2P (Peer to Peer) protocols
\n * Advanced ‘per user’ HTTP password protection with encrypted passwords
\n * RRD support for persistently storing per-host traffic information
\n * Passive remote host fingerprint (Courtesy of ettercap)
\n * HTTPS (Secure HTTP via OpenSSL)
\n * Virtual\/multiple network interfaces support
\n * Graphical Charts (via gdchart)
\n * WAP support
\n * U3 support and graphical GUI (Win32 only) <\/p>\n
