IPPP(4)                   NetBSD Programmer's Manual                   IPPP(4)


NAME

     ippp - isdn synchronous PPP network driver


SYNOPSIS

     pseudo-device ippp count


DESCRIPTION

     The ippp driver interfaces the IP subsystem of the operating system with
     the isdn layer so that a transport of IP packets over an ISDN link is
     possible.

     For configuration of the ippp driver, either the ipppctl(8) utility is
     used or it is configured via isdnd(8) and its associated isdnd.rc(5)
     file.

     In case an IP packet for a remote side arrives in the driver and no con-
     nection is established yet, the driver communicates with the isdnd(8)
     daemon to establish a connection.

     The driver has support for interfacing to the bpf(4) subsystem for using
     tcpdump(8) with the ippp interfaces.

     The ipppctl(8) utility is used to configure all aspects of PPP required
     to connect to a remote site.

LINK0 and LINK1
     The link0 and link1 flags given as parameters to ifconfig(8) have the
     following meaning for the ippp devices:

     link0  wait passively for connection

     link1  auto-dial on output

     The link0 and link1 flags are set to off by default.

     See sppp(4) for a more detailed discussion of the flags.
