8.Sh SYNOPSIS
9.Nm
--- 1046 unchanged lines hidden (view full) ---
1056.Sh PREDICTOR-1 COMPRESSION
1057
1058This version supports CCP and Predictor type 1 compression based on
1059the current IETF-draft specs. As a default behaviour,
1060.Nm
1061will attempt to use (or be willing to accept) this capability when the
1062peer agrees (or requests it).
1063
1064To disable CCP/predictor1 functionality completely, use the
1065.Dq disable pred1
1066and
1067.Dq deny pred1
1068commands.

1582
1583Some
1584.Em PPP
1585implementations use "MS-CHAP" rather than MD5 when encrypting the
1586challenge. Refer to the description of the
1587.Dq set encrypt
1588command for further details.
1589
1590.It deflate
1591Default: Enabled and Accepted. This option decides if deflate
1592compression will be used by the Compression Control Protocol (CCP).
1593This is the same algorithm as used by the
1594.Xr gzip 1
1595program.
1596
1597
1598.It lqr
1599Default: Disabled and Accepted. This option decides if Link Quality
1600Requests will be sent. LQR is a protocol that allows
1601.Nm
1602to determine that the link is down without relying on the modems
1603carrier detect.
1604
1605.It pap
1606Default: Disabled and Accepted. PAP stands for Password Authentication
1607Protocol. Only one of PAP and CHAP (above) may be negotiated. With
1608PAP, the ID and Password are sent repeatedly to the peer until
1609authentication is acknowledged or the connection is terminated. This
1610is a rather poor security mechanism. It is only performed when the
1611connection is first established.

1629PAP is accepted by default.
1630
1631.It pred1
1632Default: Enabled and Accepted. This option decides if Predictor 1
1633compression will be used by the Compression Control Protocol (CCP).
1634
1635.It protocomp
1636Default: Enabled and Accepted. This option is used to negotiate
1637PFC (Protocol Field Compression), a mechanism where the protocol
1638field number is reduced to one octet rather than two.
1639
1640.It vjcomp
1641Default: Enabled and Accepted. This option decides if Van Jacobson
1642header compression will be used.
1643.El
1644
1645.Pp
1646The following options are not actually negotiated with the peer.
1647Therefore, accepting or denying them makes no sense.
1648
1649.Bl -tag -width 20
1650.It msext
1651Default: Disabled. This option allows the use of Microsoft's
1652.Em PPP
1653extensions, supporting the negotiation of the DNS and the NetBIOS NS.
1654Enabling this allows us to pass back the values given in "set ns"
1655and "set nbns".
1656
1657.It passwdauth
1658Default: Disabled. Enabling this option will tell the PAP authentication
1659code to use the password file (see
1660.Xr passwd 5 )
1661to authenticate the caller rather than the
1662.Pa /etc/ppp/ppp.secret
1663file.
