DESCRIPTION

       EtherApe is a network traffic browser. It displays network activity graphically.  It  uses
       GNOME  libraries  as  its  user  interface,  and  libpcap,  a packet capture and filtering
       library.

OPTIONS

       These options can be supplied to the command:

       -d, --diagram-only
              don't display any node text identification

       -f, --filter <capture filter>
              set capture filter

       --final-export <export file name>
              when replaying, export to named file at end of replay

       --glade-file <filename>
              loads interface definitions from the  specified  GtkBuilder  file  instead  of  the
              default one.

       -i, --interface <interface name>
              set interface to listen to

       -l, --node-limit <number>
              sets the maximum number of node visible

       -m, --mode <link|ip|tcp>
              set mode of operation (default is ip)

       --max-delay <delay in ms>
              caps timestamps to the provided delay when replaying a capture file.

       --min-delay <delay in ms>
              provides a minimum to inter-packet delay when replaying a capture file.

       -n, --numeric
              don't convert addresses to names, disables name resolution.

       -P, --positionfile with list of nodes and columns
              Activate  column  positioning  with  the  named  file.   Manually position nodes in
              virtual columns using the named file content.  See Column Positioning.

       -q     disables informational messages.

       -r, --replay-file <file name>
              sets input file to replay

       -s     Place nodes using an alternate algorithm.  Deprecated.

       --signal-export <export file name>
              if specified, enables signal USR1 handling. On receiving USR1, EtherApe  will  dump
              its state to the named XML file.

              Beware! the file will be overwritten without asking!

       -Z, --relinquish-privileges <user>
              run everything but privileged packet-capture operations under the user ID and group
              ID of the given user.

       -?, --help
              show a brief help message

COLUMN POSITIONING

       With option -P|--position EtherApe reads a file specifying positions of  some  nodes.  The
       input file takes the format of:
         node.mydomain.com        1
         router1.mydomain.com     2
         router2.mydomain.com     2
         172.16.2.[0-9]*          1
         .*.mydomain.com          1
         ff02:.*                  2
         fe80:.*                  1

       The first column is a regex of either the FQDN or the IP address.

       The  second column is a number indicating the "column" that the node will be positioned in
       the display with column 1 being on the far left. Up to 1000 columns are permitted.

       Instead of being arranged in a circle the nodes are displayed in columns.  This  is  quite
       useful  for  arranging  nodes so that you can see nodes on the "inside" of your network on
       the left and the public internet nodes (anything not specified in the config file) on  the
       right.

       The  input  file  above  will  cause  3  columns  to  display.  Nodes with FQDN containing
       mydomain.com, those in the 172.16.2.0/24 subnet, and link local IPv6 addresses will be  in
       the  left  column.   2  "routers",  and  IPv6  multicast  will be in the center column and
       everything else will be in the right column.

       Column locations are determined by the first match while searching from  the  top  of  the
       input.   Overlapping  regex's can be used with the understanding that the first match will
       determine the location.  The broadest regex's should be near the bottom  of  the  position
       specification.

SIGNALS

       USR1   on  receipt of signal USR1, and if enabled with --signal-export, EtherApe will dump
              its state to the chosen xml file.

              Beware! the file will be overwritten without asking!

ENVIRONMENT VARIABLES

       APE_DEBUG=normal|info|debug
              controls debug output verbosity. Debug information are printed on standard output.

FILES

       Etherape will use /etc/ethers if there is one  to  convert  MAC  addresses  to  names  and
       /etc/services to associate TCP/UDP port numbers to protocol names.
