This is dying-lpd in view mode; [Up]
Date: Sun 25-Jul-1989 14:06:04 From: Unknown Subject: dying lpd I suspect that this has been hashed out before.... We are running 0.9, and our lpd keeps on getting swapped out. The printer utility thinks that it is not running, so nothing gets printed. Every time I want to print something, I have to 'su', kill the old 'lpd' (which is still running, but Sleeping and sWapped), and start a new one. This works for whatever is in the print queue, but then has to be re-done for every new document. Any ideas?

You have just described the most annoying bug with the 0.9 release. The problem is not that the daemon gets swapped out. It is *supposed* to be swapped out when it is not doing anything, and get swapped back in when it starts doing something. This is how UNIX preserves memory for processes that really need it. Almost any idle process will get swapped out eventually. NeXT has prescribed several fixes for the printer refusing to print. These have been sent out via E-Mail, and not everybody knows about them (I just got lucky that I heard). 1. The first thing you should do is log in as each and every individual user on the console, one at a time. For each user, start up the "preferences" program. There's a switch there indicating "Public Window Server." Select it so the check mark appears. For some reason, if even one user is not a Public Window Server, bad things happen to the printer. This bug should be fixed in 1.0. 2. If that doesn't work, use either the Printer app or the lpc command to make sure the printer is "started" and "enabled", although it does not sound like this will help your problem, as lpd is printing the queue on startup. 3. If the printer still is not responding, log out and log back in again. 4. If nothing is still continuing to happen, log out (on the console), log in as "exit" (no password required). When the login screen pops. back up, log in as yourself. 5. If you still are getting problems, kill the process called /usr/lib/NextPrinter/npd (you may need kill -9) and start it again. 6. As you have discovered, killing and restarting the lpd may also do the trick, although this is hardly an ideal workaround. 7. If things are really, REALLY being annoying, trying rebooting the system. It only takes a couple minutes if you have a SCSI disk (assuming you shut down with a clean file system), and various inconsistencies will automatically get cleaned up. 8. Finally, when you are absolutely at the end of your rope, your printer is making grown men cry, and even prayers to above are not being answered, try opening the printer cover momentarily and closing it. This has solved innumerable problems that even made the Printer app crash. This should not accomplish anything, but it does. Good luck. -Dan >From: bates@stat.wisc.edu (Douglas Bates)

This bug should be fixed in 1.0. I've got over 95 accounts on some of the NeXT machines here, and the above method would have been a bit tedious. For those in the same boat, a Unix solution can save you a bit of work. As root, try the following from a Shell or Terminal: # foreach i ( `nidump passwd . | awk -F: '{print $1}'` ) > echo "dwrite PublicWindowServer Yes" | su $i > end If you want to do it for the parent NetInfo domain, change the "." in "nidump passwd ." to a "..".
