HP-UX Reference (11i v2 03/08) - 1 User Commands N-Z (vol 2)

p
pppd(1) pppd(1)
9 Characters read or written
10 Procedure call messages
11 Internal timers
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.
nonice Run at a normal user process priority, rather than using the nice() library rou-
tine 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.
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.
Link Management Options
nooptions Disable all LCP and IPCP options.
noaccomp Disable HDLC Address and Control Field compression.
noprotcomp Disable LCP Protocol Field Compression.
slip Use RFC 1055 SLIP packet framing rather than PPP packet framing. Dis-
ables all option negotiation, and implies noasyncmap, noipaddress,
vjslots 16, novjcid, nomagic, nomru, and mru 1006. Implies
vjcomp if peer sends a header-compressed TCP packet.
extra-slip-end When running in SLIP mode, prepend a SLIP packet framing character (0xC0)
to each frame before transmission, even if this frame immediately follows the
previous frame. By default, pppd transmits only one framing character
between adjacent SLIP frames.
