       AMPRnet is a RIPv4 Listener and route injector daemon used with AMPRnet gateways.


       -?, -h Usage info

       -d     Debug mode: no daemonization, verbose output

       -v     More verbose debug output Using  this  option  without  debug  leaves  the  console

       -s     Save routes to /var/lib/ampr-ripd/encap.txt (encap format), if this file exists, it
              will be loaded on startup regardless of this option

       -r     Use a raw listening socket for systems with broken multicast support

       -i <interface>
              Tunnel interface to use, defaults to tunl0

       -t <table>
              Routing table to use, defaults to 'main'

       -a     <ip>[,<ip>...]    Comma separated list of IPs, hostnames  or  ampr  subnets  to  be
              ignored.   Subnets can be in full network/mask (e.g. or encap (e.g.
              44.182.20/24) format, but MUST match an entry in the RIP broadcast If a hostname is
              used,  its  IP  will  be  re-resolved  30  sec after every RIP broadcast.  The List
              contains local interface IPs by default

       -m <metric>
              Metric to be used when setting routes.  This is a numerical value from  0  to  255.
              Defaults to 0.

       -w <window>
              Sets  the TCP window size to a given value (defaults to 840).  This is needed since
              IP over AX.25 connections have small TCP window size.  A value of 0 diables setting
              the window size (not recommended, default value should be ok)

       -p <password>
              RIPv2  password,  defaults  to the current valid password. Use only if the password
              should ever change

       -f <interface>
              Interface for RIP forwarding, defaults to none/disabled

       -e <ip>
              RIP forward destination IP, defaults to if enabled

       -F <interface>
              Interface for AMPR RIP forwarding, defaults to none/disabled

       -E <ip>
              AMPR RIP forward destination IP, defaults to if enabled

       -x <system command>
              Execute this system command after route set/change. If the command  includes  white
              spaces, use quotes.

       -g <gateway>
              Gateway  for  direct 44net connections. Accepts an gateway IP or an interface name.
              If not set, it will be auto-detected.

       -L <callsign@locator>
              This parameter will enable the sending of a callsign@locator string  (actually  any
              string)  to  my  home  gateway (udp:  The string will be sent at
              starup, and then every 5 minutes. On termination, a "shutdown" string will be sent.
              On  HUP,  the string will be sent immediately and the cycle restarted.  The purpose
              of this option is to allow the construction of  a  dynamic  map  of  all  ampr-ripd
              gateways for visual display.  If the parameter is not set, no data will be sent.

              All routes are created with netlink protocol 44 for easy management.


              -  On signal SIG_HUP, ampr-ripd will delete all set routes, but will remain active,
              so routes will be set again on next received RIPv2 set, and the  saved  encap  file

              - On signal SIG_TERM (exit), ampr-ripd will delete all set routes and exit.


       With  the default debug level, using the -d option, the daemon will stay in the foreground
       and allow you to find the RIPv2 password if needed (see the shell script). To
       have  full  debug  output, it has to be compiled with -D HAVE_DEBUG or by uncommenting the
       right DOPT line.

       When using other table than 'main', interogating the routes  via  netlink  does  not  work
       properly.  This means that on any update, the route is deleted and then recreated, even if
       it is already set correctly.  This should be no problem since this happen only at  startup
       on encap loading and on route change.

       For  BGP  announced  44net  endpoints,  only  a  single  subnet may be assigned to a given
