ppl.users and ppl.ipool
ppl.users and ppl.ipool
In SLIP, ppl.users maps each user name to a single remote host. This
allows a dial-in user to invoke ppl without identifying the remote host
that is calling. It allows a dial-out user to invoke ppl without specifying
the remote host that is being called. PPP does not provide such
functionality.
The ppl.ipool in SLIP specifies a pool of local Internet addresses to be
used for modem connections. PPP does not provide such functionality.
