pppd(1) pppd(1)
Both addresses are optional, but a colon by itself is not valid, and the remote
address is required when running as a daemon in "autocall" mode. If only local:
is specified when receiving an incoming call, the remote address will be
discovered during IPCP IP-Address negotiations.
If either address is followed by a tilde character (
˜), or if the tilde appears alone,
pppd accepts the IP address given by the peer during IPCP negotiations,
whether for the local end or the peer’s end of the link (not available in SLIP
mode).
Because SLIP cannot perform option negotiations, including IPCP, both
addresses should normally be specified, and the tilde option is unavailable. To
obtain a similar "feature", the peer must provide the IP address textually during
the login process, and a new value must be obtained using the Systems file "\A"
chat script feature (see ppp.Systems(4)).
ipv6 local-ifid,remote-ifid
ipv6 should be followed by two 64-bit IPv6 interface identifiers namely, the
interface identifier of this machine and the expected interface identifier for the
remote machine.
Both interface identifiers are optional, but a comma by itself is not valid, and the
remote address is required when running as a daemon in the "autocall" mode. If
only local-ifid: is specified when receiving an incoming call, the remote interface
identifier will be discovered during IPV6CP interface id negotiations.
If either interface identifier is followed by a tilde character ˜, or if the tilde
appears alone, pppd accepts the interface identifier given by the peer during
IPV6CP negotiations, whether for the local end or the peer’s end of the link.
Note that, SLIP is not supported for IPv6 transmission. When this option is
specified along with slip option, pppd will exit with error message.
netmask subnet-mask Set the subnet mask of the interface to subnet-mask, expressed either in C-style
hexadecimal (for example, 0xffffff00) or in decimal dotted-quad notation (for
example, 255.255.255.0). The default subnet mask will be appropriate for the
network (class A, B, or C), assuming no subnetting.
need-ip-address Ask the peer to assign us an IP address.
need-ip6-ifid Get a 64-bit IPv6 interface identifier assigned by the peer.
noipaddress Disable IPCP IP-Address negotiation.
noip6ifid Disable IPV6CP interface identifier negotiation.
vjcomp Enable RFC 1144 "VJ" Van Jacobson TCP header compression negotiation with
16 slots and slot ID compression (this is the default with PPP framing). "VJ"
compression is enabled by default for async connections, and disabled by default
for sync connections.
novjcomp Disable RFC 1144 "VJ" Van Jacobson TCP header compression (this is the
default with SLIP framing, until the peer sends a header-compressed TCP
packet).
vjslots vj-slots Set the number of VJ compression slots (min 3, max 256, default 16).
novjcid Disable VJ compression slot ID compression (enabled by default).
rfc1172-vj Backwards compatibility with older PPP implementations (4-byte VJ
configuration option), but with the correct option negotiation value of 0x002d.
rfc1172-typo-vj Backwards compatibility with older PPP implementations (4-byte VJ
configuration option) that conform to the typographical error in RFC 1172 sec-
tion 5.2 (Compression-Type value 0x0037).
rfc1172-addresses Backwards compatibility with older PPP implementations that conform to RFC
1172 section 5.1 (IP-Addresses, IPCP configuration option 1) and not with the
newer RFC 1332 (IP-Address, IPCP configuration option 3), but that respond
with something besides a Configure-Reject when they receive an IPCP
Configure-Request containing an option 3.
