We have several IRIS 4D's here and I would like to do the following:
1. Be able to print to a remote Unix host and be recognized by the
Berkeley lpd daemon. In our case, I would like to spool jobs to
a QMS 800 (PostScript) laser printer hanging off a Sun4/280.
It looks like there is plenty of support for directly connected
printers, but I don't see anything on network printing other than
just rsh'ing as user "lp" and executing a print command (i.e.
/usr/spool/lp/etc/util/mknetpr). I think this is kind of crufty.
Does SGI offer an lpd clone or has someone ported the ucb one?
2. I would like to use bsd dump/restore (and rdump/rrestore) for
backups. Has anybody done this? The IRIS's really mess up our
backup scheme as we are able to do remote backup operations on
all our other machines. They can all use each others drives
and read each others tapes in case of a tape drive failures or
network problems.
I'm not saying BRU is better or worse than dump/restore, just that
it takes away this flexibility. I have not tried it yet, but it
looks I could make BRU use a remote tape drive on a arbitrary
BSD system (maybe a 6250 1/2" on a Sun?).
Other options I am considering are tar and GNU tar, since the
other systems would be able to read the tapes. GNU tar is
looking pretty attractive, since it supports full and incremental
backups/restores and will run on all of our systems.
If I missed something in the documentation, please feel free to
point this out. With the exception of the above, the IRIS was very easy
to set up in a networked environment.

Certainly would be nice, but then, IRIX *is* System V, not BSD. There is the "plp" program package (an enhanced, compatible replacement for BSD lpd and friends) that was posted to comp.sources.unix about six months to a year back, but I looked at it and it hadn't been ported to system V. If someone has the time and gets this working, please post. > 2. I would like to use bsd dump/restore (and rdump/rrestore) for backups. Here here! I've been using Gnu tar on both of our System V machines, since I certainly don't want to use the 60 Mb cartridge tape drives to backup a 280 Mb disk drive. You could go broke trying to buy enough cartridge tapes for a couple of months worth of monthly, weekly, and daily backups. Gnu tar required some work to get it working on the Iris.

Yes, I've ported the bsd lpr to a 40/70GT running 3.1B. It took me a two or three days to do, it took me that long to figure out what exactly was missing. With a little help it should take a day or two. Somewhere a symbol is being redefined, I believe SGI has a problem with some of their include files being reincluded, but that isn't too hard to deal with. Here's what I had to do as best as I can reconstruct. (I didn't do this with diff/patch because I'm sure everyones' lpr is hacked up differently). Because of licencing I shouldn't be more specific than this. Good Luck - david Files that need changing... <bsd/exec.h> <bsd/sys/un.h> /* Add to file system */ <bsd/sys/ioctl.h> lp.h lpd.c lpr.c printjob.c startdaemon.c What to do in general... 1) SGI does not support UNIX sockets, so change all UNIX sockets to INET sockets. ifdef out any code for UNIX sockets. 2) Get copies of exec.h and un.h and put them in /usr/include/bsd/exec.h /usr/include/bsd/sys/un.h 3) chown by name is not supported, use fchown lookout for argument changes
