.B linkname \fIname\fR
Sets the logical name of the link to \fIname\fR. Pppd will create a
file named \fBppp\-\fIname\fB.pid\fR in /var/run (or /etc/ppp on some
local system to the peer. (Note that pppd does not append the domain
name to \fIname\fR.)

+Set the IPV4 network mask on the PPP interface to the given

+hexadecimal number preceded by 0x. This option is not normally
+needed because the PPP interface is a point-to-point connection, but

Disable Address/Control compression in both directions (send and
receive).

Ask the peer for up to 2 WINS server addresses. The addresses supplied

Pppd invokes scripts at various stages in its processing which can be
used to perform site-specific ancillary processing. These scripts are
usually shell scripts, but could be executable code files instead.

executed as root (with the real and effective user-id set to 0), so

privileged daemons. Be careful that the contents of these scripts do

+WARNING: Please note that on systems where a single interface carries multiple

+should consider using net-pre-up instead, alternatively, disable other NCPs
