exec exec-cmd Run exec-cmd up addr args when the link comes up, and exec-cmd

down

addr args when it goes down. Addr is the IP address of the peer, and args is

the list of arguments given to

pppd.

exec6 exec-cmd Run IC exec-cmd " up " "interface-id args" when the link comes up, and exec-

cmd

down interface-id args when it goes down. Interfac-id is the 64-bit IPv6

interface identiﬁer of the peer, and args is the list of arguments supplied to

pppd. This is

router6 When IPv6 is enabled, the

IFF_PRIVATE ﬂag will not be set to IPv6 interface

so that the interface is able to forward IPv6 datagrams. Also, this interface

will not be able to receive any router advertisement packets for conﬁguring the

IPv6 secondary interface. Instead, use the

ifconfig command or stateful

conﬁguration methods like DHCPv6 to conﬁgure the IPv6 secondary interface.

noipv4 When speciﬁed, IPCP negotiation will not take place and no IPv4 datagrams

will pass through the link.

noipv6 When speciﬁed, IPV6CP negotiation will not take place and no IPv6

datagrams will pass through the link.

nonice Run at a normal user process priority, rather than using the nice() library

routine to elevate pppd scheduling priority to -10.

Communications Options

asyncmap async-map Set the desired Async Control Character Map to async-map, expressed in C-

style hexadecimal notation (default 0xA0000).

noasyncmap Disable LCP Async Control Character Map negotiation.

escape odd-character In addition to those characters speciﬁed in the PPP Async Control Character

Map (which can include only 0x00 through 0x1F), also apply the escaping

algorithm when transmitting odd-character. The value of odd-character must

be between 0x00 and 0xFF, and cannot be any of 0x5E, 0x7D or 0x7E.

Odd-character can be speciﬁed as a decimal number, in C-style hexadecimal

notation, or as an ASCII character with optional

ˆ control-character notation.

For example, the XON character could be speciﬁed as 17, 0x11, or ˆQ.

If a character speciﬁed with the

escape argument, when transformed into its

escaped form, would be the same as a character contained in the peer’s nego-

tiated Async Control Character Map, a warning will be printed in the log ﬁle

and the character speciﬁed on the command line will not be escaped.

If a character speciﬁed with the

escape argument, when transformed into its

escaped form, would be the same as a character speciﬁed in another escape

argument on the daemon’s command line, pppd will print an error message

and exit.

device Communicate over the named device (default /dev/tty).

comm-speed Set communications rate to comm-speed bits per second. Recommend values

By default, Internal-clocking cannot be used with RS-232

ignore-cd Ignore the state of the CD (Carrier Detect, also called DCD, Data Carrier

Detect) signal. This is useful for systems that don’t support CD but want to

run PPP over a dedicated line.

xonxoff Set the line to use in-band ("software") ﬂow control, using the characters DC3

(ˆS, XOFF, ASCII 0x13) to stop the ﬂow and DC1 (ˆQ, XON, ASCII 0x11) to

resume. (The default is to use no ﬂow control.) For an outbound connection,

this may be speciﬁed either in Devices or on the pppd command line.

telnet When used on an answering pppd command line, negotiate the telnet binary

option and understand telnet escape processing. Not for use with device or

auto.
