Brian Somers 6b4286e0f5 Wait by default for one second after the login script
is complete before checking carrier.  If it's there,
the device supports carrier.  If it's not it doesn't.

Add the ``set cd'' command for deciding how soon to check
for carrier, and for deciding if carrier is REQUIRED.

The default has changed:  Pre 2.0 versions of ppp waited
for 1 second.  Version 2 didn't wait, but this causes
problems with some (few?) modems that don't assert carrier
immediately on reporting CONNECT.  The one second delay
is back now and can be removed with ``set cd 0''.

Bump the ppp version number in case this needs to be changed
again....

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' (was `set ns') 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.
o If you don't like seeing additional interface aliases when running in
-auto -alias mode, add ``iface clear'' to your ppp.linkdown file -
check the sample file.
o Ppp waits for 1 second before checking whether the device supports
carrier. This is controllable with ``set cd''.
