NAME ehnt -- Extreme Happy Netflow Tool. Client part SYNOPSIS ehnt [-0 ASN] [-a ASN] [-b] [-c count] [-i mins] [-m mode] [-n intidx] [-p port] [-P proto] [-r addr] [-s server:port] [-x prefix] DESCRIPTION The ehnt command starts ehnt(1) client which connects to ehntserv(8) server and converts raw flow of NetFlow version 5 packets into human- readable (or machine-readable) form. Ehnt currently has two basic modes of operation, dump and top. The dump modes are used to output details about individual flows. Top mode is used to generate reports which display averages over time for AS numbers, IP protocols and TCP/UDP ports. The options are as follows: -0 ASN Replace AS number 0 occurences with this AS number -a ASN Only display flows to/from this AS number -b Display big flows (only shows flows with the most bytes or packets received so far) -c count Exit after <count> flows are received -h Display command-line help -i mins How long to wait between report generations (in minutes) -m mode The name of the mode of operation to use: dump displays flow detail; shortdump shows flow details in a more compact fashion; colondump shows flow details in a machine-readable format; top generates reports of top average utilization -n intidx Specify the interface by SNMP ifIndex number -p port Only display flows to/from this tcp or udp port number -P proto Only display flows using this IP protocol number -r addr Only display flows reported by this router IP address -s server:port The hostname or IP address and port number of the ehntserv(8) -t topmode The type of report to generate when in top mode. (The re- port type can also be changed interactively while the pro- gram is running.) as; Display the AS report proto; Display the IP protocol report tcpport; Display the TCP port report udpport; Display the UDP port report -v Display the ehnt version number. -x prefix Only display flows to/from this IP prefix. The format for <prefix> is 'address/length', for example 1.2.3.4/30 or 127.0.0.0/8.
