798ba6f53e Don't bring the modem offline or hangup when ``down lcp''
is done.  Instead, behave like ``close lcp''.

13defc3317 Fix a rather nasty use of `static'. This caused a SEGV
when running ``link * load label'' as we ended up recursing
back into command_Interpret after nuking our command arg list.

3f8652a301 Give ``load'' optional context. It's now possible to
``link 1,2,3 load label'' for people that want to set
up their links in a more mpd-like manner.

4ea5840027 Make `close lcp' just close the LCP layer and not hangup. This is
useful for slirp users that wish to get their shell back after the
ppp session.  `close' with no args still hangs up as expected.

0cb00afb55 o Maintain a link-type mask for open datalinks as well as
for all datalinks in a bundle.  Ppp now deals correctly
  with link types that are changed while open
o When changing the type of the last AUTO link, only clear
  the interface if we're not in PHASE_NETWORK.  This allows
  us to switch to -ddial mode while we have a connection
  without suddenly unexpectedly throttling ourselves by
  clearing the interface configuration.

36b1e9c4f0 o Make modes consistent throughout ppp. The same strings are used
in `set mode', `allow modes', on the command line and when
  outputting mode names.  The strings are matched so that only
  enough characters to uniquely identify the string are required,
  so you can now

    ppp -a mylabel  (for auto mode)
    ppp -b mylabel  (for background mode)
    ppp -dd mylabel (for direct dial mode)

  etc.
o Make -ddial dial when specified on the command line (oops).

a847940420 o Fix a few comment typos.
o Fix ``set timeout'' usage message and documentation.
o Change ifOutPackets, ifOutOctets and ifOutLQRs to `u_int32_t's
  so that they wrap correctly.
o Put the LQR in network byte order using the correct struct size
  (sizeof u_int32_t, not sizeof u_long).
o Wrap LQR ECHO counters correctly.
o Don't increment OutLQR count if the last LQR hasn't been replied
  to.
o Initialise HisLqrData (last received LQR) in StartLqm.
o Don't start the LQR timer if we're `disabled' and `accepted'.
o Generate LQR responses when both sides are using a timer and
  we're not going to send our next LQR before the peers max timeout.

LQR should now be fully functional.

1c9a27b464 Cosmetic:
Don't mention the authors name at startup.  He's already credited
  in the man page.  Instead, make the message consistent with the
  one given to the diagnostic port (and fix the grammar when entering
  `term' mode).
  Don't credit the zlib author in the man page as ppp isn't linked
  directly with zlib (it's shared).
  Mention when the OpenBSD port was first made available.

f1d93f530b Don't allow manual dialing unless in auto or interactive mode. 1998-01-23 04:36:42 +00:00

7443167983 Allow an optional delay when specifying "set openmode active".
The delay defaults to 1 sec (as it always has) unless we've done
a ~p in interactive mode or we've actually detected a HDLC frame.
This is now cleanly implemented (via async timers) so that it is
possible for LCP to come up despite the delay if an LCP REQ is
received.

This will hopefully solve situations with slow servers or slirp
scenarios (where ECHO is left on the port for a second or so before
the peer enters packet mode).

Also, ~p in interactive mode no longer changes the value of the default
openmode delay and -dedicated mode enters packet mode in the right state
according to the value of openmode.

6fd0acab5e o Allow the use of HISADDR as the first arg to "add".
o Allow a forth argument in ppp.secret, specifying a new
  label.  This gives control over which section of
  ppp.link{up,down} is used based on the authenticated user.
o Support random address ranges in ppp.secret (not just in ppp.conf).
o Add a AUTHENTICATING INCOMING CONNECTIONS section to the man page.
o Add a bit more about DEFLATE in the man page.
o Fix the incorrect "you must specify a password in interactive
  mode" bit of the manual.
o Space things in the man page consistently.
o Be more precice about where you can use MYADDR, HISADDR and INTERFACE
  in the "add" command documentation.

69deecd8ae Allow "set device" to close the open modem if we're in
interactive mode.
Use `netfd' in fcntl() and tc[gs]etattr() calls rather than
the hard coded descriptor 0.
Use _FILENO constants from unistd.h

This un-breaks things after my recent `close(0)' in interactive
mode.

Close STDIN_FILENO, and open _PATH_TTY O_RDONLY as `netfd'.  This
has the effect of allowing `show route' to output more than about
a page of data (on FreeBSD, not OpenBSD....).  I have no idea why,
except that it was a direct consequence of the tcsetattr() in
TtyCommandMode().  My previous fix (closing descriptor 0) `fixed'
this because all calls to tcsetattr() failed :-(

b51dc6a0ad Allow random IP number allocation to peer.
Validate the peers suggested IP by attempting to make a routing table
entry.
Give up IPCP negotiation if the peer NAKs us with an unusable IP.
Always SIOCDIFADDR then SIOCAIFADDR when configuring the tun device.
Using SIOCSIFDSTADDR allows duplicate dst addresses (which we don't
want)!!!
Allow up to 200 interface names (was 50) (now that ppp can play server
properly).
Up the version number (1.5 -> 1.6).

Cosmetic:
  Log unexpected CCP packets in the CCP log rather than the ERROR log.
  Log unexpected Config Reqs in the appropriate LCP/IPCP/CCP log rather
  than the ERROR log.
  Log failed route additions and deletions with WARN, not TCPIP.
  Log the option id and length for unrecognised IPCP options.
  Change some .Sq to .Ar in the man page.

brian
1a5893522d Only allow one arg to `delete' - the mask & gateway aren't necessary.
Delete AF_LINK routes as well as AF_INET.
Allow the word `default' as the arg to `delete' or in place of the
first two args (dest & netmask) to `add'.
Accept INTERFACE as the third arg to `add'.

  You can now say `add default interface' to create a default route
  through the tun interface.  It's reported that subsequent bind()s
  will bind to a broadcast address and not to the address currently
  assigned to the tun device - this is the first step towards
  supporting that first connection that was around from before the
  dynamic IP negotiation....

0c64913a0f Finish the security improvements:
o Add "allow" command:
      "allow users a b c" gives access to users a, b and c.
      "allow modes auto"  gives those users access to auto mode only.
      "allow users *" and  "allow modes *" are accepted.
      No users and all modes are allowed by default.
    UID 0 can do anything.
  o Set the current label with the "load" and "dial" commands
    so that the call to ppp.linkdown makes sense.
  o Up the verison number.
  o Don't OR MODE_AUTO for -background and -ddial.
  o Don't OR MODE_INTER when we get a diagnostic connection.
  o Allow up to 40 args per line (was 20).
  o "set ifaddr" only changes the interface in AUTO mode (with other
    modes, it happens after IPCP negotiation).
  o Sort command descriptions in the man page.
  o Support -dedicated mode where we just talk ppp forever (no login etc).
