ax25rtd is a daemon that:
- emulates the ceased "autorouter" of Linux Kernel AX.25
- sets up ARP entries automagically
- may adjust IP routes and encapsulation mode
(although I really do not recommend to use this feature...)
The "autorouter" is not really an autorouter. It just listens to the AX.25 traffic on your ports and uses
this information to setup AX.25 routes. This can be turned on or off by altering the configuration file
/etc/ax25/ax25rtd.conf.
Ax25rtd provides a socket /var/ax25/ax25rtd/control which is used for runtime maintenance through
ax25rtctl or to set up new routes by other daemons (a Flexnet router, perhaps?)
On startup ax25rtd reads the configuration file and afterwards preloads the caches from the files
/var/ax25/ax25rtd/ax25_route and /var/ax25/ax25rtd/ip_route. On SIGTERM or ax25rtctl--save it saves the
caches to those files.
