This file summarises changes made to ppp that effect
its configuration.
It does not describe new features, rather it attempts
to answer any `this used to work, why doesn't it now?'
questions.
o The `set debug' command was replaced with `set log'.
o The `set log LCP' command was split into LCP, IPCP and CCP logs.
o Syslogd is used for logging. /etc/syslog.conf must be updated.
o LQR is disabled by default.
o Openmode is active by default.
o Users must be a member of group `network' for ppp access. Furthermore,
they must be `allow'ed to run ppp via the `allow' command in the
configuration file.
For a brief period, ppp could only be run as root.
o No diagnostic socket is created by default. The `set server' command
must be used.
o The diagnostic socket password must be specified *only* on the `set
server' command line.
o When `set server' is used to re-select a diagnostic port, all existing
diagnostic connections are dropped.
o pppd-deflate is now called deflate24.
o Filter IPs of 0.0.0.0 have a default width of 0, not 32.
o Errors in `add' and `delete' are logged as warnings rather than being
written to the TCP/IP log.
o Any number of diagnostic prompts are allowed, and they are allowed in
interactive mode.
o The default `device' is cuaa1, then cuaa0
o A password of "*" in ppp.secret causes a passwd database lookup in
pap mode.
o The value of the CONNECT environment variable is logged in the
utmp host field in -direct mode.
o Out-of-sequence FSM packets (IPCP/LCP/CCP) are dropped by default.
o Reconnect values are used after an LQR timeout.
o ^C works on the parent in -background mode.
o The dial/call/open command works asynchronously. As a result, prompts
do not lose control while dialing.
o The `display' command has been removed. All information is available
with the appropriate `show' command.
o Msext does not need to be enabled/disabled. Setting the NBNS (set nbns)
will auto enable it. The DNS side may be enabled/disabled, and if
enabled without a `set dns' will use values from /etc/resolv.conf.
o Filters are now called `allow', `dial', `in' and `out'. `set
ifilter ...' becomes `set filter in ...' etc.
o Authname and Authkey may only be `set' in phase DEAD.
o Set encrypt is no longer necessary. Ppp will respond to M$CHAP
servers correctly if it's built with DES.
o Throughput statistics are enabled by default.
o `Set stopped' only has two parameters. It's no longer possible to
have an IPCP stopped timer.
o `Set timeout' only has one parameter. Use `set lqrperiod' and `set
{lcp,ccp,ipcp,chap,pap}retry' for the other timers. `show timeout'
is also now available using the relevant show commands.
o `set loopback' is now `enable/disable loopback'.
o `show auto', `show loopback' and `show mtu' are all part of `show bundle'.
o `show mru' is part of `show lcp'
o `show msext' and `show vj' are part of `show ipcp'
o `show reconnect' and `show redial' are part of `show link'
o A signal 15 (TERM) will now shut down the link gracefully.
o A signal 2 (HUP) will drop all links immediately.
o Signal 30 (USR1) is now ignored.
o Add & delete commands are not necessary in ppp.linkup if they are
`sticky routes' (ie, contain MYADDR or HISADDR).
o LINK and CARRIER logging are no longer available.
o Timer based DEBUG messages are now logged in the new TIMER log.
o Ppp can use tun devices > tun255.
o Protocol-compressed packets are accepted even if they were denied
at LCP negotiation time.
o Passwords aren't logged when logging the ``set server'' line.
o Command line options only need enough characters to uniquely identify
them. -a == -auto, -dd == -ddial etc. -interactive is also allowed.
