GENERAL INFORMATION
This is version 6.0 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 for some time ow 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. See COMPATIBILITY
below for details.
The current version of rdist is available via anonymous ftp on usc.edu
under /pub/rdist. The current version is always retrievable as file
"/pub/rdist/rdist.tar.Z".
CHANGES/FEATURES
See the ChangeLog file for details. The end of the file contains the
major new features compared to rdist classic.
A paper titled "Overhauling Rdist for the '90s" from USENIX LISA VI
is available for anonymous ftp on usc.edu as "/pub/rdist/overhaul.ps.Z".
PLATFORMS
This version of rdist has been tested on the following:
MACHINE TYPE OPERATING SYSTEM
--------------- ----------------------------------
Alliant 2800 Concentrix 2.2
Alliant FX/80 Concentrix 5.X
DEC MIPS Ultrix 4.2
HP 9000/300 Mt Xinu MORE/bsd (4.3BSD)*
HP 9000/300 HP/UX 7.05 (HP cc)
HP 9000/400 HP/UX 7.05 (HP cc)
HP 9000/700 HP/UX 8.07 (HP cc, GCC 2.3.1)
IBM RS6000 AIX 3.2
NeXT Mach 2.2, 3.0
Sun-3 SunOS 4.0.3, 4.1.1
Sun-386i SunOS 4.0.1
Sun-4 SunOS 4.0.3, 4.1.1, 4.1.2, 4.1.3
Multiflow 4.3 BSD TRACE/UNIX Version 5.0.4
MIPS RISC/os 4.51, 5.0
* Not recently tested. Known to work at some point in the past.
It should work on just about any BSD based Unix with little or no
modification. It will probably work on modern System V based OS's
such as SVR4 with some work.
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).
The definetion _PATH_OLDRDIST in 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.
INSTALLATION
1) Edit "Makefile" and follow the comments on what parameters may need to
be set and/or changed.
2) Edit "config.h" and follow the comments on what parameters may need to
be set and/or changed.
3) Run "make" to compile everything.
4) Run "make install" to install the binaries and "make install.man" to
install the manual pages.
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

NOTES
IBM AIX
I use a modified definition for "bsdcc" in /etc/xlc.cfg for compiling
rdist under AIX 3.X:
* standard c compiler aliased as bsdcc
bsdcc: use = DEFLT
crt = /lib/crt0.o
mcrt = /lib/mcrt0.o
gcrt = /lib/gcrt0.o
libraries = -lbsd, -lc
proflibs = -L/lib/profiled,-L/usr/lib/profiled
options = -H512,-T512,-qlanglvl=extended,-qnoro,-D_BSD,-Dunix=1,
-D_NONSTD_TYPES, -D_NO_PROTO, -D_BSD_INCLUDES, -tp,
-B/lib/
HP/UX
All of this information on HP/UX is third-hand. I don't have
access to any HP/UX machines to test rdist on.
Unlike HPUX version 7, version 8 does not come standard with yacc
which is now part of the C/ANSI C Development Bundle. If that bundle
is on the system, then rdist compiles fine with the changes to the
Makefile to include regex.o and strcasecmp.o. If you don't have yacc
and instead use the GNU bison in the yacc mode (-y option) it compiles
fine but needs to have the PW library included (-lPW) in order to find
an alloca.o when linking.
The regex that is part of the HPUX C library is not compatible with
the BSD style regex that rdist uses. Someone who leaves regex.o out
of the MISSINGOBJS line in the Makefile because they noticed a
regex(3) in the HPUX manual set is going to have a problem.
OLD rcmd() LIBRARY BUG
Very Old 4.2BSD-based Unix systems may have a bug in their rcmd()
library function. The bug allowed a user process to run out of file
descriptors if too many connection attempts failed. The problem is
that the socket would never be closed if the connect() failed. This
could eventually lead to running out of file descriptors if enough
connections failed. Most current Unix's like SunOS 4.0.3 and later
have this fixed. Here is a diff to (I think) the SunOS 3.5 rcmd() to
fix the problem:
***************
*** 51,56 ****
--- 65,71 ----
timo *= 2;
goto retry;
}
+ (void) close(s);
perror(hp->h_name);
return (-1);
}

AIX and NeXT by disabling SETARGS.
Wed Nov 11 10:42:27 1992 Michael A. Cooper (mcooper@acamar.usc.edu)
* When NOCHKOWNER and NOCHKGROUP are enabled, don't check
directory ownership.
* Make getmountent() work again for AIX.
Tue Nov 10 15:09:59 1992 Michael A. Cooper (mcooper@acamar.usc.edu)
* Version 6.0beta.9
Mon Nov 9 13:19:51 1992 Michael A. Cooper (mcooper@acamar.usc.edu)

to act like the original version when dealing with rdisting
directories to symlinks. The original rdist simple ignored the
condition where the target on a remote host was a symlink when the
target on the master was a directory. The new rdist will
automatically make the target on the remote host be the same as

cleared when they were suppose to be, even when it said it was
being cleared. The mode of a file/directory would also not be set
in certain cases. This bug looks to date back to the original version.

* Change "register char i" to "register int i" in docmd().
* Fixed another bug with "Don't know how to rdist to ...". This
time, a much simplier approach was taken to remove the "unused"
stuff from the last fix.
* Save argc and argv from main() into realargc and realargv
before setargs() overwrites.
Fri Aug 28 16:36:34 1992 Michael A. Cooper (mcooper@acamar.usc.edu)
* The primary group of the owner of a file was not being checked
in fchog(), which resulted in the setgid bit being cleared.

* Fix problem with ETXTBSY code not working. (Neal Becker)
* Add support for HP 9000/[78]00 executable format. (Neal Becker)
* Defining SETARGS breaks "special" command under HP/UX. (Neal Becker)
* Change #ifdef's of "hpux" to be "__hpux" for compability
with both HP/UX 7.* and 8.* OS versions. (Neal Becker & Allan Weber)
* Get rid of #define's in defs.h by compiling yacc with -d.
Also change tokens like SM (';') to be real chars in the grammer
instead of tokens for clarity. (Rich)
* Change ISDIR -> S_ISDIR, ISREG -> S_ISREG, ISLNK -> S_ISLNK
to be POSIX compliant. (Rich)
* Document in rdist.1 how rdist runs rdistd.
* Replace ".in +5" with ".RS/.RE" in rdist.1. (Rich)
* Remove preprocessor support. Use "m4 distfile | rdist -f -"
for same effect without the ugly code. (Rich)
* Clarify -N and -O options in rdist.1 (Rich).
* Document that we can't use strchr() in place of any() because
most systems strchr() can't handle some of the input we pass.
Changes up to Release 6.0beta.2:
Tue Aug 4 15:20:46 1992 Michael A. Cooper (mcooper@acamar.usc.edu)
* Rename patchlevel.h to version.h and move VERSION define

* Fix bug with ^C of "rdist" resulting in a core dump. An invalid
jmpbuf was being used in a call to longjmp().
* Fix problem with modify time not being set on NeXT 2.1 machines.
Also now set the access time of newly installed/updated file to
be the current time instead of the atime from the source machine.

Thu Jul 16 10:58:09 1992 Michael A. Cooper (mcooper@acamar.usc.edu)
* Fix problem with hosts marked as + in the distfile having
multiple child update the host simaltaneously, which causes race
conditions when updating certain targets.

Sun-386i (SunOS 4.0.1), DEC MIPS (Ultrix 4.2), NeXT (Mach 2.1).
Mainly this was changes to config.h and creation of isexec.c
to make porting to new platforms more straigtforward.
Changes up through 6.0alpha
- The client and the server are now split into two seperate programs
(rdist and rdistd). The client (rdist) looks like older versions of
rdist. Instead of running "/usr/ucb/rdist" on a remote machine, it
now runs "rdistd". Notice that it doesn't run "/usr/ucb/rdistd"
or use any explicit pathname. This is to improve portability to
various different platforms where "/usr/ucb" may not exist. What
this means is that the server must be somewhere in the user's default
$PATH if the client is to successfully run rdistd.
This also means that the server no longer needs to be setuid root.
Only the client still needs setuid root (because it uses priv'ed
ports). This should cut down a bit on potential security holes.
Because the server (rdistd) resides in normal user "bin" directories,
it requires the -S option in order to run. This is to avoid users
accidentially typing "rdistd" instead of "rdist".
- If the client (rdist) is started with the "-Server" option (which
is the old rdist method of starting rdist in server mode), it
will attempt to run the old version of rdist, if it was compiled
with the name of that program. This is for backwards compatibility
and should allow this version of rdist to co-exist with older versions.
- Add support for running a pre-processor (m4 by default) over the
distfile before processing.
- If a connection to a host fails, avoid trying to recontact host
again.
- Use getopt() for command line option parsing. I hate getopt(), but
everybody wants to use it. Sigh.
- A slew of new options. See the man page for details.
- Add buffered remote read code from Chris Torek along with some other
code cleanups.
- Check free space and files on a filesystem before installing.
This code will (optionally) check the amount of free space
and files (inodes) on a filesystem before installing. If the
free space and/or files is less then specified by the initiator,
then the target will not be installed and an error returned.
This is useful for preventing rdist from filling up a remote
filesystem.
- Concurrent rdist processes.
Update multiple hosts concurrently by fork'ing children
with each child updating one host. The number of
children is limited to a given number (usually 4), but is
controllable with a command line option (-M).
- Add "setargs" code to set process arguments to indicate what host
we are talking to. A protocol change was required for this.
- If a remote target resides on a NFS or read-only filesystem,
then don't try to update target on that host. This elimates
having to have millions of seperate lists and exceptions
for hosts with certain parts NFS mounted or read-only mounted
and hosts with everything mounted read-write.
- Set timeout alarms to avoid hanging when something happens
to a server during a session. Remove servers can sometimes
get into a state either during startup or during a session
where they will never send a response back to the local rdist
master process.
- Add ability to rdist a symlink to a directory and vice-versa.
Previously, this would fail.
- Add checking and setting of file modes. If a file's mode is not
what it should be, the entire file is updated in case there was
any tampering. If the target is a directory, then just the mode
of the directory is updated.
- Major code cleanup and restructuring. Major portions of the code
has been re-written and/or restructured.
- Add config.h file for configuration related items.
- Fixed a security hole with setreuid().
- Add better error messages. We now distinguish between LOCAL and
REMOTE errors.
