pppd(1) pppd(1)
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 dur-
ing the login process, and a new value must be obtained using the Systems file
‘\A’ chat script feature (see ppp.Systems (4)).
netmask subnet-mask Set the subnet mask of the interface to subnet-mask, expressed either in C-
style hexadecimal (e.g. 0xffffff00) or in decimal dotted-quad notation (e.g.
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.
noipaddress Disable IPCP IP-Address 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.
Authentication Options
requireauth Require either PAP or CHAP authentication.
requirechap Require CHAP authentication as described in RFC 1334.
requiremschap Require MS-CHAP authentication.
requirepap Require PAP authentication.
rechap interval Demand that the peer re-authenticate itself (using CHAP) every interval
seconds. If the peer fails the new challenge, the link is terminated.
name identifier Provide the identifier used during PAP or CHAP negotiation. This option is
necessary if the PPP peer requires authentication. The default value is the
value returned by the gethostname(2) system call or the hostname (1) com-
mand.
MicroSoft Compatibility Options
ms-dns address Set the MS DNS address to provide to the peer. First occurrence of this option
on the command line sets the primary address; the second occurrence sets the
secondary address.
ms-nbns address Set the MS NBNS address to provide to the peer. First occurrence of this
option on the command line sets the primary address; the second occurrence
sets the secondary address.
Encryption Options
Encryption is not currently available in software exported from the USA. However, customer may contact
[e-mail] to obtain encryption functionality.
