This is most likely a candidate for 2.1, too.
slattach always exited early because fd is not open in acquire_line().
Other (trivial) changes that I've been neglecting for some time:
- Turn off O_NONBLOCK so that `chat' doesn't need to worry about it
(`chat' actually does worry about it).
- Really set speeds POSIXly :-). cfsetspeed() isn't POSIX.
- Fix spelling error in comment.
- Gripe about bad programming of doing everything from signal handlers.
slattach should be written to do everything from the sigsuspend() loop,
but I don't want to do it :-).

sighup handler now sets tty disc for non-redial case too.
Implement SIGURG handling (from keepalive).
POSIXing speed settings.
-K: set keepalive SLIP timeout
-O: set outfill SLIP timeout
Handle SIGURG from keepalive like SIGHUP now, i.e. reconnect.
Back out background scription change, cause some synchro problems.
Now works with dialin devices too.
Add new option in slattach style -l: dont use modem control.
Add new option -W: specify max number of dial tries for one phone.
Remove -p option, this ugly hack not needed.
Fix script timeout expires.
Some code cleanups.
Add -t to specify login script timeout.
Add -w to specify retry wait time.
Describe -p option.
Now understand several -s sections (for several host phone numbers).
Remove -F sw (software flow control), it is impossible with slip.
Change -F hw (hardware flow control) option to -h as in slattach,
we don't need option with argument for only one case.
Call downscript on SIGTERM.
Improve debug diagnostic.
Allow startslip work with several slip lines without killing each other.
Unlink pid file on exit.
Skip \r and \0 in login script parsing instead making them \n.
Use absolute path to default script (/sbin/ifconfig).
Call up/down script in background to prevent hang on them.
understand why it can become a null pointer under some circumstances,

- getnetgrent.c: address some NIS compatibility problems. We really need
to use the netgroup.byuser and netgroup.byhost maps to speed up innetgr()
when using NIS. Also, change the NIS interaction in the following way:
If /etc/netgroup does not exist or is empty (or contains only the
NIS '+' token), we now use NIS exclusively. This lets us use the
'reverse netgroup' maps and is more or less the behavior of other
platforms.
If /etc/netgroup exists and contains local netgroup data (but no '+').
we use only lthe local stuff and ignore NIS.
If /etc/netgroup exists and contains both local data and the '+',
we use the local data nd the netgroup map as a single combined
database (which, unfortunately, can be slow when the netgroup
database is large). This is what we have been doing up until now.
Head off a potential NULL pointer dereference in the old innetgr()
matching code.
Also fix the way the NIS netgroup map is incorporated into things:
adding the '+' is supposed to make it seem as though the netgroup
database is 'inserted' wherever the '+' is placed. We didn't quite
do it that way before.
(The NetBSD people apparently use a real, honest-to-gosh, netgroup.db
database that works just like the password database. This is
actually a neat idea since netgroups is the sort of thing that
can really benefit from having multi-key search capability,
particularly since reverse lookups require more than a trivial
amount of processing. Should we do something like this too?)
- netgroup.5: document all this stuff.
- rcmd.c: some sleuthing with some test programs linked with my own
version of innetgr() has revealed that SunOS always passes the NIS
domain name to innetgr() in the 'domain' argument. We might as well
do the same (if YP is defined).
- ether_addr.c: also fix the NIS interaction so that placing the
'+' token in the /etc/ethers file makes it seem like the NIS
ethers data is 'inserted' at that point. (Chances are nobody will
notice the effect of this change, which is just te way I like it. :)

The version 2 support has been tested (client+server) against FreeBSD-2.0,
IRIX 5.3 and FreeBSD-current (using a loopback mount). The version 2 support
is stable AFAIK.
The version 3 support has been tested with a loopback mount and minimally
against an IRIX 5.3 server. It needs more testing and may have problems.
I have patched amd to support the new variable length filehandles although
it will still only use version 2 of the protocol.

There is also an undocumented option in the man page that can be dangerous.
Suppose your disk driver decides to scramble all writes while you tell

you to push the same host into its NFS export lists twice, but mountd
tries to do it anyway. This means that putting:
/some_file_system -ro host1 host1
in your /etc/exports file causes an error. This is bogus: mountd should be
smart enough to ignore the second instance of host1. This can be a problem
in some configurations that use netgroups. For example, each host in my
netgroups database is has two entries:
startide (startide,-,) (startide.ctr.columbia.edu,-,)
When mountd sees this, it tries to put startide.ctr.columbia.edu into the
export list *twice*. Just listing 'startide' /etc/exports list will also
screw up because mountd will try to resolve the netgroup 'startide' instead
of the hostname 'startide.'
My solution is watch for duplicate entries in get_host() and mark them
as grouptype GT_IGNORE, which do_mount() will now cheefully throw away.
This is a bit of a kludge, but it was the least obtrusive fix I could
