At the request of Microsoft IT, two simple identification features were added - a non-cryptographic password and an identification protocol named the Bloodhound-Oriented Network Entity (BONE) (created and named by Raymond Patch as a play on the codename Bloodhound). Network Monitor 3 is a complete overhaul of the earlier Network Monitor 2.x ...
Iftop is a free software command-line system monitor tool developed by Paul Warren. It produces a real-time stream of incoming and outgoing network communications from the operating system iftop is running within. [2] By default, the connections are ordered by bandwidth usage, with only the largest ("top") bandwidth consumers shown.
A network tap is an even more reliable solution than to use a monitoring port since taps are less likely to drop packets during high traffic load. On wireless LANs , traffic can be captured on one channel at a time, or by using multiple adapters, on several channels simultaneously.
Wireshark is very similar to tcpdump, but has a graphical front-end and integrated sorting and filtering options.. Wireshark lets the user put network interface controllers into promiscuous mode (if supported by the network interface controller), so they can see all the traffic visible on that interface including unicast traffic not sent to that network interface controller's MAC address.
EtherApe, a graphical tool for monitoring network traffic and bandwidth usage in real time. Firesheep, a discontinued extension for the Firefox web browser that captured packets and performed session hijacking; iftop, a tool for displaying bandwidth usage (like top for network traffic) Kismet, for 802.11 wireless LANs
A common usage is to monitor network traffic by polling a network switch or router interface via Simple Network Management Protocol (SNMP). The Cacti end user front end supports both User and User Groups security models and supports Role Based Access Control (RBAC) for access to not only monitoring data, but various areas of the user interface.
Monitor mode, or RFMON (Radio Frequency MONitor) mode, allows a computer with a wireless network interface controller (WNIC) to monitor all traffic received on a wireless channel. Unlike promiscuous mode , which is also used for packet sniffing , monitor mode allows packets to be captured without having to associate with an access point or ad ...
nslookup, used to query a DNS server for DNS data (deprecated on Unix systems in favour of host and dig; still the preferred tool on Microsoft Windows systems). vnStat, useful command to monitor network traffic from the console. vnstat allows to keep the traffic information in a log system to be analyzed by third party tools.
