- This is the README file for version 1.06 of the Taylor UUCP package.
-
- It was written by Ian Lance Taylor. I can be reached at ian@airs.com,
- or, equivalently, uunet!cygint!airs!ian, or c/o Cygnus Support,
- 48 Grove Street, Somerville, MA 02144, USA.
-
- There is a mailing list for discussion of the package. The list is
- hosted by Eric Schnoebelen at cirr.com. To join (or get off) the
- list, send mail to taylor-uucp-request@cirr.com. Mail to this address
- is answered by the majordomo program. To join the list, send the
- message ``subscribe ADDRESS'' where ADDRESS is your e-mail address.
- To send a message to the list, send it to taylor-uucp@cirr.com. The
- old list address, taylor-uucp@gnu.ai.mit.edu, will also work. There
- is an archive of all messages sent to the mailing list at ftp.cirr.com.
-
- This package is covered by the Gnu Public License. See the file
- COPYING for details. If you would like to do something with this
- package that you feel is reasonable but you feel is prohibited by the
- license, contact me to see if we can work it out.
-
- The most recent version may be obtained from any Gnu archive site.
- The canonical site is prep.ai.mit.edu. There are many mirror sites,
- including ftp.uu.net and wuarchive.wustl.edu.
-
- WHAT IT IS
-
- This is the complete source code for a Unix UUCP package. It provides
- everything you need to make a UUCP connection. It includes versions
- of uucico, uusched, uuxqt, uux, uucp, uustat, uulog, uuname, uuto,
- uupick, and cu, as well as uuchk (a program to check configuration
- files), uuconv (a program to convert from one type of configuration
- file to another) and tstuu (a test harness for the package).
-
- This is the standard UUCP package of the Free Software Foundation.
-
- The package currently supports the 'f', 'g' (in all window and packet
- sizes), 'G', 't' and 'e' protocols, as well a Zmodem protocol, the FX
- UUCICO 'y' protocol, and two new bidirectional protocols. If you have
- a Berkeley sockets library, it can make TCP connections. If you have
- TLI libraries, it can make TLI connections. It supports a new
- configuration file mechanism which I like (but other people dislike).
-
- The package has a few advantages over regular UUCP:
-
- You get the source code.
-
- It uses significantly less CPU time than many UUCP packages.
-
- You can specify a chat script to run when a system calls in,
- allowing adjustment of modem parameters on a per system basis.
-
- You can specify failure strings for chat scripts, allowing the
- chat script to fail immediately if the modem returns ``BUSY''.
-
- If you are talking to another instance of the package, you can use
- the new bidirectional protocol for rapid data transfer in both
- directions at once. You can also restrict file transfers by size
- based on the time of day and who placed the call.
-
- On the other hand:
-
- It only runs on Unix. The code is carefully divided into system
- dependent and system independent portions, so it should be
- possible to port it to other systems. It would not be trivial.
-
- You don't get uuclean, uusend, uuq, uusnap, uumonitor, uutry,
- uupoll, etc. If you have current copies of these programs, you
- may be able to use them. Shell scripts versions of uuclean and
- uutry are provided, with most, if not all, of the functionality of
- the usual programs. I believe the supplied uustat program allows
- you to do everything that uuq, uusnap and uumonitor do. uupoll
- could be written as a shell script.
-
- The package does not read modemcap or acucap files, although you
- can use V2 configuration files with a BNU Dialers file or a dialer
- file written in my new configuration file format.
-
- The package cannot use SCO dialer programs directly, although it
- can with a simple shell script interface.
-
- If you start using this package, I suggest that you join the mailing
- list (see above) to keep up to date on patches and new versions. I am
- also open to suggestions for improvements and modifications.
-
- DOCUMENTATION
-
- The documentation is in the file uucp.texi, which is a Texinfo file.
- Texinfo is a format used by the Free Software Foundation. You can
- print the documentation using TeX in combination with the file
- texinfo.tex. DVI, PostScript and info versions of the documentation
- are available in a separate package, uucp-doc-1.06.tar.gz.
-
- See the TODO file for things which should be done. Please feel free
- to do them, although you may want to check with me first. Send me
- suggestions for new things to do.
-
- The compilation instructions are in uucp.texi. Here is a summary.
-
- Edit Makefile.in to set installation directories.
-
- Type ``sh configure''. You can pass a number of arguments in the
- environment (using bash or sh, enter something like ``CC=gcc
- configure''; using csh, enter something like ``setenv CC gcc; sh
- configure''):
- CC: C compiler to use; default is gcc if it exists, else cc
- CFLAGS: Flags to pass to $CC when compiling; default -g
- LDFLAGS: Flags to pass to $CC when only linking; default none
- LIBS: Library arguments to pass to $CC; default none
- INSTALL: Install program; default install -c or cp
- The configure script will compile a number of test programs to see
- what is available on your system, so if your system is at all
- unusual you will need to pass in $CC and $LIBS correctly.
-
- The configure script will create config.h from config.h.in and
- Makefile from Makefile.in. It will also create config.status,
- which is a shell script which actually creates the files. Please
- report any configuration problems, so that they can be fixed in
- later versions.
-
- Igor V. Semenyuk provided this (lightly edited) note about ISC
- Unix 3.0. The configure script will default to passing -posix to
- gcc. However, using -posix changes the environment to POSIX, and
- on ISC 3.0, at least, the default for POSIX_NO_TRUNC is 1. This
- means nothing for uucp, but can lead to a problem when uuxqt
- executes rmail. IDA sendmail has dbm configuration files named
- mailertable.{dir,pag}. Notice these names are 15 characters long.
- When uuxqt compiled with -posix executes rmail, which in turn
- executes sendmail, the later is run under POSIX environment too!
- This leads to sendmail bombing out with 'error opening 'M'
- database: name too long' (mailertable.dir). It's rather obscure
- behaviour, and it took me a day to find out the cause. I don't
- use -posix, instead I run gcc with -D_POSIX_SOURCE, and add
- -lcposix to LIBS.
-
- On some versions of BSDI there is a bug in the shell which causes
- the default value for CFLAGS to be set incorrectly. If ``echo
- ${CFLAGS--g}'' echoes ``g'' rather than ``-g'', then you must set
- CFLAGS in the environment before running configure. There is a
- patch available from BSDI for this bug. (Reported by David
- Vrona).
-
- On AIX 3.2.5, and possibly other versions, cc -E does not work,
- reporting ``Option NOROCONST is not valid.'' Test this before
- running configure by doing something like
- touch /tmp/foo.c
- cc -E /tmp/foo.c
- This may give a warning about the file being empty, but it should
- not give the ``Option NOROCONST'' warning. The workaround is to
- remove the ",noroconst" entry from the "options" clause in the
- "cc" stanza in /etc/xlc.cfg. (Reported by Chris Lewis).
-
- Examine config.h and Makefile to make sure they're right.
-
- Edit policy.h for your local system.
-
- Type ``make''.
-
- Use ``uuchk'' to check configuration files. You can use
- ``uuconv'' to convert between configuration file formats.
-
- Type ``make install'' to install. Note that by default the
- programs are compiled with debugging information, and they are not
- stripped when they are installed. Read the man page for strip for
- more information.
-
- On older System V based systems which do not have the setreuid
- system call, problems may arise if ordinary users can start an
- execution of uuxqt, perhaps indirectly via uucp or uux. UUCP jobs
- may wind up executing with a real user ID of the user who invoked
- uuxqt, which can cause problems if the UUCP job checks the real
- user ID for security purposes. On such systems, it is safest to
- put ``run-uuxqt never'' in the `config' file, so that uucico never
- starts uuxqt, and invoke uuxqt directly from cron.
