Besides starting local daemons, `/etc/rc.local' is useful for
slattach. In order to not block
any networking-services that are also started in `/etc/rc.local',
the corresponding command should occur quite early, best place is after
`/etc/motd' is generated.
Configure `/etc/hostname.ppp0' or `/etc/hostname.sl0' and `/etc/mygate' as described above. Also, change the baudrate to fit your needs.
# Start SLIP-networking echo -n 'Preparing SLIP-interface ... ' slattach 9600 /dev/tty00 >/dev/null 2>&1 echo -n 'ready.'
# Start PPP-networking echo -n 'Preparing PPP-interface ... ' pppd /dev/tty00 9600 echo -n 'ready.'The big problem that stays with PPP is that you've to start it up on the other side at (exactly) the same time, and there must no timeout occur in order to get a connection. Use SLIP if this is a problem.
Note that there's barely a way to dial out during boot-time, so the above mainly belongs to direct (nullmodem) connections.
