859be0911a Add an IPv6 support. 
I dunno if there is an IPv6 supported rexec client.  So, it was
tested that this change doesn't break an IPv4.

e1b4d8d074 Use STD{ERR,IN,OUT}_FILENO instead of their numeric values. The 
definitions are more readable, and it's possible that they're
more portable to pathalogical platforms.

20934175ae Goodbye S/Key, Hello OPIE. 
I believe I have done due dilligence on this, but I'd appreciate
decent test scenarios and sucess (or failure) reports.

does not have a null password).

a51e2c9b04 Julian A's fix. Do chdir as user rather than as root. Fixes a minor NFS 
compatibility problem at the same time.  Some buffer made large enough
for worst case hostname.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$ 
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.

a13e275f66 Back out recent security patch for rexecd. After more careful analysis, 
it is both uneeded and breaks certain lock-step timing in the rexec
protocol.

Yes, an attacker can "relay" connections using this trick,  but a properly
configured firewall that would make this sort of subterfuge necessary in the
first place (instead of direct packet spoofing) would also thwart useful
attacks based on this.

that people who have a need to run it don't hurt themselves so badly.
