GENERAL INFORMATION
|
|
|
|
This is version 6.1 of Rdist from USC. It is based on rdist from
|
|
4.3BSD (classic). It includes all fixes for all bugs known to the
|
|
CSRG Berkeley folks. It has been running at USC and numerous other
|
|
sites for some time now on a wide variety of platforms.
|
|
|
|
This version of rdist is not directly compatible with rdist
|
|
distributed with 4.3BSD and subsequent vendor releases, but does
|
|
indirectly provide full backward compatibility.
|
|
|
|
CHANGES/FEATURES
|
|
|
|
This version of rdist does not need to be setuid "root" at all. Rdist
|
|
now uses the rsh(1c) [remote command] program to make connections to
|
|
remote hosts, instead of making the connection directly. This
|
|
eliminates the need to be run as "root". Many thanks to Chris
|
|
Siebenmann <cks@utcc.utoronto.ca> and John DiMarco
|
|
<jdd@cdf.toronto.edu> who came up with an rsh version of rcmd() that
|
|
makes this possible.
|
|
|
|
This version supports automatic system determination and configuration
|
|
for pre-ported platforms. This means that rdist knows how to
|
|
completely configure and compile itself for a number of platforms.
|
|
Users don't need to worry about modifying any files to compile on a
|
|
supported platform.

PLATFORMS
|
|
|
|
This version of rdist has been ported to most major and a number of
|
|
not so major platforms. The list below is only a partial list.

COMPATIBILITY
|
|
|
|
This version of rdist differs greatly from older versions (as
|
|
distributed with 4.3BSD) in that the client and the server portions
|
|
are seperated into two distinct programs, rdist and rdistd,
|
|
respectively. The protocol used to communicate between the client and
|
|
server has also been extensively modified. These two items make
|
|
providing "builtin" compatibility very difficult. However, backwards
|
|
compatibility is possible, provided you have a binary or source copy
|
|
of the old rdist.
|
|
|
|
The way the old rdist started a server rdist is to run "rdist
|
|
-Server". If the new rdist is run with the "-Server" option, then it
|
|
will exec a copy of the old rdist (usually /usr/old/rdist or
|
|
/usr/ucb/oldrdist). In this way, you get compatibility with hosts
|
|
running the old rdist attempting to rdist to a machine running new
|
|
rdist. If your host running new rdist wants to rdist to a host
|
|
running the old rdist, then it must run the old rdist program
|
|
(/usr/old/rdist or /usr/ucb/oldrdist).
|
|
|
|
[[ for FreeBSD; /usr/bin/rdist is the "old" rdist, and /usr/local/bin/
|
|
[[ is the location of the "new" rdist and rdistd.
|
|
|
|
The definition _PATH_OLDRDIST in "config/config.h" controls the
|
|
location of the old rdist. If this is not defined, or the defined
|
|
program does not exist at runtime, then rdist will print an error when
|
|
run with the "-Server" option.
|
|
|
|
BUG REPORTS
|
|
|
|
Bug reports should be sent to "rdist-bugs@usc.edu". All bug reports
|
|
should include:
|
|
|
|
1) The version of the rdist client and server you are running
|
|
(use the -V option to rdist and rdistd)
|
|
2) The platform (machine + OS name + OS version)
|
|
3) A full description of the problem, including sample distfiles.
|
|
4) If you have a patch to fix the problem, a context diff (diff -c)
|
|
of the original files vs. the fixed files
