I am looking into getting two 340C+ workstations to run some of the Ideas MCAE (CAD) software from SDRC. I have an HP D size plotter, an hp A/B size plotter, Hayse 1200 baud modem, and an epson LQ1000 printer avialible to me if I can use them. My problem is that according to the "HP 9000 HP-UX Operating System" pamplet "only the cluster servers can support spooled peripherals". Unfortunately the 340 has only one serial port and I am told that I can not put both a 4-port rs-232 mux card and a high speed disk interface (either HP-IB or SCSI) in the 340. I would like to put the mux card on the workstation I plan on using as a diskless node, but then I run into the problem with spooled periphs off a diskless node. I also have an hp310 which has its own 55Meg disk and free DIO slots, but no lan card, and it is running hp-ux 5.0, which didn't include ns-arpa or nfs when we got it (a few years ago). Now I don't care if I hook the 310 into the 340's, but I do need to hook the printer and at least one plotter into the 340's (and I can not use hp-ib to talk to the plotters). AND I got to do this cheaply, I am already planing on spending a little more than has been aproved. Any insights would be greatly appreciated. thanx. Mic@sun.soe.clarkson.edu (128.153.12.3)

>I can use them. My problem is that according to the "HP 9000 HP-UX Operating >System" pamplet "only the cluster servers can support spooled peripherals". That's true. Only the server *supports* spooled peripherals. Spooling to a diskless cnode has been configured locally; I believe remsh was used to do the dirty work. Note that support implies 'clean'. Our approach may not be 'clean', but gets the job done. >I also have an hp310 which has its own 55Meg disk and free DIO slots, but >no lan card, and it is running hp-ux 5.0, which didn't include ns-arpa or >nfs when we got it (a few years ago). To get nfs, you need at least 6.0. To get 6.0, you need at least an 80Mb disk. It's probably too costly to upgrade the 310 to be a useful member of this network. Also, 6.5 is the last HP-UX release to support 310's. You might look into a trade-in instead. Bill Bennett hpfcse!hpubmaa!web

Spooled peripherals on a diskless node are not officially supported, but it's not impossible to do this. To achieve this, try doing the following (strictly unsupported, caveat emptor): Turn the following files/directories into CDF's: /usr/spool/lp/ FIFO SCHEDLOCK pstatus qstatus outputq request /* this is a directory - see below */ default /* if you want different default printers */ If you make "request" a CDF, it will create the directories under request in only the rootserver's context. You must manually copy the contents to the other contexts. If you want a local printer for each cnode, try the following in addition: make /usr/spool/lp/interface/lp (or whatever you want to call it) a CDF. Then on each client, set up "lp" as desired (most diskless workstations have an RS232 port or an HP-IB port, so you can set up the local printer appropriately.) ---- Shankar.

Consider using named pipes instead of remsh. Have the lp spooler on the diskless server cat to the pipe, and from inittab on the diskless node set up a cat from the pipe to the device... It's been a while since I did this, so details aren't fresh in my mind, but it worked great... Bdale "now sitting in a cubicle near a laser printer..."
