32af26a501 Use realhostname() rather than various combinations of
gethostbyaddr() & gethostbyname().

Remove brokeness in ftpd for hosts of MAXHOSTNAMELEN length.

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.

fixes PR 2593.

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.

Never allow the reverse channel to be to a privileged port.

3f59b9c4ef rexecd was not calling "setlogin()" when it should have. This was causing
getlogin() to return wrong answers (eg: "root").

50dfa3861b Don't rely on the shared library bringing in libmd, do it explicitly.
Change the library order so libcrypt is the last library in the list.
libskey contains references to _crypt and can't resolve it unless
-lcrypt occurs after it in the link command.  This only occurs when
linking statically.

cda3118c2e Tighen up rexecd(8) security (see manual page for details).
Rexecd is a crock, it never should have been written,  however make it so
that people who have a need to run it don't hurt themselves so badly.
