The eui64.[ch] and ipv6cp.[ch] were taken from ppp-2.3.11.
However, our stock pppd(8) doesn't provide option_t nor some
utility functions. So, I made some hacks to adjust to our
stock pppd(8).
The sys_bsd.c part was taken from NetBSD with some
modifications to adjust to our stock pppd(8).
MFC after: 1 week
- (see auth.c rev 1.13) allow the pap/chap secrets file to specify an
override for the otherwise hard coded IP addresses. This allows specific
users to dial in on a rotary which would otherwise get a dynamic address
forced to authenticate and get their own fixed addresses.
- (see options.c rev 1.9) recognize the old dns1 and dns2 options. This
is a hack (TM). :-)
dial-on-demand, packet filtering, idle timeouts, etc). The IPX support
is pretty much there but more work needs to be done in sys-bsd.c for
the interface ioctls (Linux has a very different way of configuring IPX
interfaces).
Along the way some things have temporarily been lost due to very messy
conflicts. I will recover them shortly when I can think clearer.
The main one is the local:remote address override in pap-secrets and
chap-secrets. Some other home-grown features (dns1,dns2) have been
implemented differently. Microsoft's chap client auth hacks have been
implemented. There are bound to be more rough edges... The changes for
connect-max-retries doesn't fit well with the dial-on-demand code.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
bomb out. Unfortunately, FreeBSD's sio driver and certain internal
modems don't get along very well, which can cause the serial port to
wedge until it is closed and reopened.
Add new variable, connect-max-attempts, default = 1 (to mimic previous
behavior). If > 1, will try up to "n" times to dial remote site before
aborting.
