INSTALLATION GUIDE README 5.6 85/06/24 This version is based on the "rti uucp" that was on the 4.2BSD tape. It contains many additional features and fixes from Usenet, Tom Truscott, Guy Harris, Lou Salkind, and many others. A few new subdirectories have been added. Do a "make mkdirs" to make sure that you have all of them. I recommend that you change the uucp mail handler in your sendmail.cf to something like: # Muucp, P=/usr/bin/uux, F=sDFMhuU, S=13, R=23, M=100000, # A=uux - -r $h!rmail ($u) Muucp, P=/usr/bin/uux, F=sDFMmhuU, S=13, R=23, M=100000, A=uux - -r -z -a$g -gC $h!rmail ($u) The -a$g provides a return address in case mail fails (So It won't go to yourmachine!uucp anymore.) The -gC specifies a grade for mail. C is a good choice for mail. News should run at 'd'. This way, mail gets sent before news. The 'm' flag specifies that this mail can send to multiple addresses, which uux can. The man pages now describe all the options for the various commands. Make sure you read them. A list of the functional differences is in "Changes". You should also look through the UUAIDS directory. There are some useful programs and hints therein. The maximum length of a site name has been changed from the old 7 to the 14. This is the be compatible with the HoneyDanBer uucp (aka BNU 1) which is as close to a standard uucp as there is. Sites which have sitenames longer than 7 characters that only send you the first 7 characters are broken and should be fixed. However, there is a way of compensating for this until they fix their problem. For each site you talk to that has a name longer that 7 characters, put a line in /usr/lib/uucp/L.aliases of the form: fullname name-truncated-to-7-characters. E.g: tektronix tektron lbl-csam lbl-csa rochester rochest ut-sally ut-sall (See UUAIDS/L.aliases for more details on aliasing uucp names.) If the site name is <= 7 characters, you don't have to do anything.

There have been tons of bug fixes and enhancements from people on the usenet (thank you). Speed is substantially improved. This version fixes essentially all of the McGeady's bug list. Enhancements: Dialers Lots of dialers included. Subdirectories /usr/spool/uucp is now split into 7 subdirectories. This is a huge help on busy systems. /usr/lib/uucp/L.cmds List of commands permitted for remote execution. A line of form 'PATH=...' sets the search path. expect-send sequence Escape characters now permitted: \r, \n. \r, not \n, is default char sent at end of string. \c (put at end of string). Dont send ending \r. \d pause 1 second (\d\d pauses 2 seconds) "" P_ZERO `expect nothing, start sending zero parity.' P_EVEN (default), P_ODD, P_ONE other parity modes. \05 Send a control-E "" "" `expect nothing, send a \r'. uupoll [sysname] Polls named system. uusnap Displays spooled files, and pending uuxqts. This version runs on all VAXen and PDPs under UNIX-V7 and 4.1bsd, 4.2BSD. It also runs on Gould/SEL Concept series machines (e.g. 32/8750), DUAL 68000 unisoft. It also runns on BTL system III, IV, and V. UUCP installers should read the two papers (by Dave Nowitz) in Vol 2B of version 7 manuals and UUAIDS/setup.tblms. Understand each step below before executing. Some steps will vary slightly from system to system. **** INSTALLATION ******* 1. If you are currently running uucp, save the old programs!: su root cd /usr/bin for i in uucp uux uulog uuname (csh: foreach i (uucp ....) ) do cp $i $i.old done (csh: end ) cd /usr/lib/uucp for i in uucico uuxqt uuclean do cp $i $i.old done 2. Editing Makefile and uucp.h 4.2 sites using the supported dialers are all set with defaults. non-4.2 a) sites need to install the Berkeley directory reading library. Try (cd libndir; make install). Edit Makefile to have LIBNDIR= -lndir define NDIR in uucp.h. b) Check LDFLAGS, OWNER, GROUP, and LIBUUCICO. c) pick a method to allow uucp to know its system: Check out GETHOSTNAME/UNAME/WHOAMI/CCWHOAMI in uucp.h d) define SYSIII if appropriate in uucp.h. e) Your "make" may fail because the Makefile is so large. If so, in /usr/src/cmds/make/defs, change '#define NFLEFTS 60' to 512, and re-make make. 3. Make the new commands. make 4. WAIT UNTIL THE UUCP SYSTEM IS IDLE!! Single-user is best. su root (it is important that chmod, chown and chgrp work below) 5. Install the new commands: make install (If you are chicken, type 'make -n install' first). 6. Edit and install the control files: Look in UUAIDS. Edit and install into /usr/lib/uucp if necessary USERFILE, L.cmds, L.sys, L-devices, L-dialcodes. THESE FILES MUST BE OWNED BY THE SAME OWNER AND GROUP AS THE UUCP COMMANDS AND UUCP SPOOL FILES!!! (probably uucp, daemon). The format for dialers is slightly different so that any dialer can be handled. 7. Make new subdirectories: For safety: cd /usr/spool/uucp; tar c . (save Qed files on tape) The following assumes your site name is produced by `uuname -l`. make mkdirs If your system is duke, then the subdirectories created are named C., D., D.duke, D.dukeX, TM., XTMP and X.. rmdir /usr/lib/uucp/.XQTDIR which is obsolete (XTMP replaces it). 8. Move old Qed files: If you have spooled files, they must be moved into the subdirectories. Assuming all spool files are in /usr/spool/uucp (i.e. you did not have subdirs before) the following command will move the spool files to the right subdirectories: make mvspoolfiles; ??? does this work now?????????? Files beginning C. are put in the C. subdirectory, and so on. Files begining D.dukeX are put in that directory, *not* D.. (Note: if you already had a subdirectory version of uucp, you need only create the new subdirectories mentioned above and move the relevant files there. Delete other old directories if you had any (e.g. "LOG.") 9. Compact /usr/spool/uucp: cd /usr/spool mkdir nuucp chown uucp nuucp chgrp daemon nuucp for i in uucp/* (csh: foreach i (uucp/*) ) do mv $i nuucp done (csh: end ) rmdir uucp mv nuucp uucp (Note: this does *not* work if a filesystem is mounted on /usr/spool/uucp! If that is the case, you should 'tar' /usr/spool/uucp somewhere, unmount, re-mkfs, and re-mount the filesystem, and tar the uucp files back.) 10. Test the new system Test by mailing a letter somewhere and back. If it works, the new system is probably fine. Otherwise, figure out what is wrong. Start by examining LOGFILE. Try /usr/lib/uucp/uucico -r1 -sname -x7 If things are no-go, you can back out the changes by restoring the old uu programs and the spooled files. NOTE: The subdirectories foul up a non-subdir version, so be sure that subdirectories exist/do not exist as appropriate. 11. Install handy UUAIDS Look in uuaids for handy other stuff. In particular, uu.* are shell scripts that can be run via cron hourly, daily, and weekly to keep uucp trim. L-devices, L-dialcodes, L.cmds, L.sys, USERFILE are sample files. THEY MOST LIKELY NEED TO BE MODIFIED TO USE THEM ON YOUR OWN SYSTEM! uu.hourly Makes sure sites are polled. uu.daily Runs uuclean to clean up /usr/spool/uucp. **IT HANDLES SUBDIRECTORIES!! Renames LOGFILE to LOGFILE.old. uu.weekly Renames SYSLOG to SYSLOG.old. The above scripts should be run via cron. uucpsummary Summarizes LOGFILE and SYSLOG. It's very helpful in telling what is going on and who is calling who. uucp.daily Daily shell script run at ittvax. Manages SYSLOG files in a convenient form for uuusage. Not integrated in time for this distribution. Comments, bug reports, *and improved code* are welcome. Tom Truscott Bob Gray
