(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) command.
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
sales@progressive-systems.com to obtain encryption functionality.
Link Compression Options
compress Offer all supported link compression types (currently only Predictor-1) when
negotiating. The default is to propose and accept no link compression type.
compress-pred1 Accept any supported compression type, but prefer Predictor type 1 compression.
nopred1 Never use Predictor-1 compression.
LOG FILE
Status information is recorded in the log file (/var/adm/pppd.log by default) by each copy of pppd
running on a single machine. Each line in the file consists of a message preceded by the date, the time, and
