SCO PPP features
This release of SCO PPP provides:
Support for up to 64, simultaneous PPP links.
Support for PPP communications initiated on the local host and
PPP communications initiated from a remote host.
Use of serial lines dedicated to a single PPP link or use of
serial lines on an as-needed basis (dynamic acquisition)
allowing for the sharing of serial lines with cu and UUCP
Dynamic IP addressing.
SCO PPP can be configured for the dynamic allocation
of IP addresses during PPP negotiation.
Either the local host or the remote host can allocate IP addresses.
IP address pooling. A remote access endpoint can assign
IP addresses from a predefined pool of IP address pairs.
Dynamic PPP link configuration, which negates the need to
relink the kernel or stop/restart TCP/IP to make changes to PPP link
endpoints. Further information is contained in
``Signaling the PPP daemon''.
Two-level priority packet handling.
The PPP driver implements a two-level priority scheme in the
handling of packets.
Given highest priority over other packets, but equal priority
among themselves, are rlogin, telnet,
and ftp packets.
All other packets are handled as a lower priority.
SCO PPP provides a mechanism for specifying what types
of IP packets (for example, those carrying FTP data versus
those carrying RIP data) will pass through a PPP network
interface, bring up a PPP network
interface, or reset the idle timer of a PPP network interface.
For more information, see
``PPP packet filtering''.
