We're having some trouble with LAT printers under Ultrix 4.1. The jobs seem to print out okay, but then Ultrix doesn't let go of the port (SHOW SESSIONS PORT 1 on the DECserver says that the port is still connected to the Ultrix system). The next time a job is submitted to that printer queue, Ultrix thinks that the port is busy and marks the queue as stalled. I can logout the DECserver port, and Ultrix will print again until the queue is empty. Then it's locked up again. Most of our printers are shared by multiple systems, and all of the rest of them are VMS systems. The VMS systems have no trouble with the port. The DECserver in question is a DS100, running version 2.0 of the DS100 software. Has anyone else experienced this? Better yet, does anyone know how to fix it? I'm almost tempted to set all the queues up to use lpr to one of the VMS nodes!! :-) -- Don Rainwater, Systems Manager, Univ. of Cincinnati Computer Center Don.Rainwater@UC.Edu rainwatr@ucunix.san.uc.edu rainwatr@ucbeh.bitnet ...!uccba!ucunix!rainwatr

We've had this problem for some time and have reported it to DEC and gotten nowhere with it. We share LAT printers between VMS and ULTRIX all over campus and quite often ULTRIX will get ahold of the port and not let go, stopping printing altogether until the port is logged out. However, I was just at USENIX and someone there told me that he has exactly the same setup that we have here and he has no problems. He alluded to some- thing in the release notes for 4.[01], although I didn't see anything that looked like it would help. In case anyone is interested, we're running LP27's on DECserver200's. We're running VMS 5.4 in a cluster and ULTRIX 4.1 on a MicroVAX II. I'm not sure what software version is running on the DECservers but I can find out. If *ANYONE* has a fix for this, I would forever be in your debt. -- Leonard Peirce Internet: peirce@gumby.cc.wmich.edu Western Michigan University peirce@gw.wmich.edu Academic Computing Services UUCP: ...!uunet!sharkey!wmichgw!peirce Kalamazoo, MI 49008 Phone: (616) 387-5469

Well, I seem to have to made a little progress in solving this, although things aren't exactly the way they should be. Basically what I did was specify the server and port when starting lcp in rc.local instead of putting them in the printcap entry. Things don't hang anymore but for some reason I keep getting errors in the log file about not being able to open the device. I have also noticed that *sometimes* when a job is pending, lpd won't start up. I say sometimes because I was testing this repeatedly the other day and it would work perfectly about 90% of the time and the other 10% I would lpr a file and lpd would just sit there. The port was free; lpd just ignored the file. After I would restart lpd, things would be fine. I thought I was losing my mind for a while so I kept trying it and kept getting the same results. I decided to let it go for a while and see if anyone complains and I haven't heard a word from anyone. Hmmm.... So... I have the printer in my office working again so I'm going to test this some more. Maybe I was losing my mind (temporarily)..... At least the port doesn't hang up and our VMS users don't scream because they can't get things printed. If I only had source....:-) -- Leonard Peirce Internet: peirce@gumby.cc.wmich.edu Western Michigan University peirce@gw.wmich.edu Academic Computing Services UUCP: ...!uunet!sharkey!wmichgw!peirce Kalamazoo, MI 49008 Phone: (616) 387-5469
