EPAN is a protocol analyzer for ethernet networks. The program allows
you to display the received frames either in an overview mode or in a frame
detail mode. It is also possible to create a few statistics (frame size
distribution, utilization or protocol statistics). For more detailed statistics
EPAN offers to use an external program like gnuplot to evaluate the collected
data. Data acquisition is done by a separate program called edump (similar
to an RMON probe). This program can capture data from the following devices:
| Unix version | Supported network media |
| Linux v2.x and above | Ethernet, Token-Ring, SLIP, PPP, ISDN, ARCnet, Local Loopback, Dummy Device |
| FreeBSD | Ethernet and Local Loopback |
| Solaris 2.5 and above | Ethernet and Local Loopback |
| DEC Ultrix | Ethernet and Local Loopback |
| DEC Unix | Ethernet and Local Loopback |
To get an idea of how EPAN looks like please have a look at the following
screenshots.
EPAN currently runs on Linux 2.x and FreeBSD 2.2 systems
with X11R6 installed and supports the following protocols:
| Protocol family | Protocols |
| TCP/IP | MAC Ethernet, MAC IEEE 802.3, LLC (IEEE 802.2), SNAP, ARP, RARP, IP (incl. IPIP and IP-ENCAP), ICMP, IGMPv1, IGRP, TCP (incl. 9 TCP options), UDP, DNS (incl. 22 Resource Records), SUN RPC, TFTP, BOOTP/DHCP (incl. 63 vendor options), RIPv1, RIPv2, RWHO, TIME, DAYTIME |
| Novell | IPX, SPX, SAP, RIP |
| IBM | NetBIOS / NetBEUI |
| DECnet phase IV | |
| Banyan Vines | |
| ISO |
