OS :Windows all Size :3.3 MB License :GPL Update date :June 12th, 2007 Download nTop 3.3ntop is a software very similar to the popular top Unix command and it is a network traffic probe that will show you the network usage. 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. The use of: · a web interface · limited configuration and administration via the web interface · reduced CPU and memory usage (they vary according to network size and traffic) · make ntop easy to use and suitable for monitoring various kind of networks. Here are some key features of "nTop": · Sort network traffic according to many protocols · Show network traffic sorted according to various criteria · Display traffic statistics · Store on disk persistent traffic statistics in RRD format · Identify the indentity (e.g. email address) of computer users · Passively (i.e. withou sending probe packets) identify the host OS · Show IP traffic distribution among the various protocols · Analyse IP traffic and sort it according to the source/destination · Display IP Traffic Subnet matrix (who's talking to who?) · Report IP protocol usage sorted by protocol type · Act as a NetFlow/sFlow collector for flows generated by routers (e.g. Cisco and Juniper) or switches (e.g. Foundry Networks) · Produce RMON-like network traffic statistics · VoIP support (SIP, Cisco SCCP and Asterisk IAX) · NetFlow (including v5 and v9) and IPFIX support · Network Flows · Local Traffic Analysis · Multithread and MP (MultiProcessor) support on both Unix and Win32 · Perl/PHP/Python lightweight API for accessing ntop from remote · Support of both NetFlow andsFlow as flow collector. ntop can collect simultaneously from multiple probes. · Traffic statistics are saved into RRD databases for long-run traffic analysis. · Internet Domain, AS (Autonomous Systems), VLAN (Virtual LAN) Statistics · Network assets discovery and categorization according to their OS and users · Protocol decoders for most of known P2P (Peer to Peer) protocols · Advanced 'per user' HTTP password protection with encrypted passwords · RRD support for persistently storing per-host traffic information · Passive remote host fingerprint (Courtesy of ettercap) · HTTPS (Secure HTTP via OpenSSL) · Virtual/multiple network interfaces support · Graphical Charts (via gdchart) · WAP support · U3 support and graphical GUI (Win32 only) Requirements: · From a few MB (little LAN) to 100 MB for a WAN. · On a modern PC and large LAN, it is less than 10% of overall CPU load.
