We have several printers attached to machines running SunOS 4.1 and have a couple of SysV machines that would like to use these printers. What's the best way to do this? 1. try to port lpd to sys V machines (Source is available from Berkeley, I believe.) 2. write custom program to ftp files and run remote process 3. ???

The patches for lpr/lpd to run on System V have been posted to alt.sources, and I have made them available via mail for quite some time now. Here is the readme. Mon May 21 12:49:15 PDT 1990 While 386/ix (tm Interactive) has a number of network services from BSD, lpr is not one of them. This does not cause a real problem, as the shell scripts of lp can be used to perform remote printing. It is not a very good solution when interacting with other Sun or BSD systems. Jonathan C. Broome <wilbur!jon> did the original port to 386/ix from the freed lpr sources. I added a few modifications, and re-did the context diffs from the tar file on uunet (~ftp/bsd-sources/src/network/lpr.tar.Z) No guarantee that this will work for you, but it works for me. To use: Unpack the shell archive, then apply the two patch files lpr.diff.1 and lpr.diff.2 with patch. The unaltered source files from the lpr tar file must be used. The C files included must be in the lpr directory.

Create and install a dummy printer using the sys5 lp utilities.
[see lpadmin(1m)]
Use the script in /usr/spool/lp/model/dummy to rsh or remsh to a Sun
and pipe into lpr.
(If I remember correctly you have to close the file descriptor for
standard output in the script with exec or it hangs).
This can rsh or remsh to a sun and pipe into lpr.
This is easier than 1. or 2. but doesn't handle job listing or cancelation.
It means that software on the sys5 box can still print to lp though.

We have a similar setup and I found that it was necessary to test the result status from rsh (well, we have rcmd on our TCP/IP implementation) and retry after eg 30 seconds if the connection failed. Thus you get (approximately), : while : : do : if cat "$MYFILE" | rcmd "$RHOST" -l "$RUSER" lp ... : then : break : else : sleep 60 : fi : done Chris -- VISIONWARE LTD | UK: chris@vision.uucp JANET: chris%vision.uucp@ukc 57 Cardigan Lane | US: chris@vware.mn.org BANGNET: ...!ukc!vision!chris LEEDS LS4 2LE, England | VOICE: +44 532 788858 FAX: +44 532 304676 -------------- "VisionWare: The home of DOS/UNIX/X integration" -------------

Stevens, in his book "Network Programming", gives an lpr client as one of his examples. You can FTP the code from the book from: uunet.uu.net: pub/netprog.tar.Z Or, I could mail you a hack I did. I started with LPR.C from PC/IP and now I have lpr, lpq and lprm for SysV (tested on Convergent Tech. and SGI), but there is almost no LPR.C code left :-) -- bmw@isgtec.uucp [ ..uunet!utai!lsuc!isgtec!bmw ] Bruce Walker
