Well, I finally upgraded to version 3.5 and things seem to be running
smoothly, except...
I have a few programs which run on pc's and store data on a mounted
filesystem. I've been writing to files with names like "mp-100t-910503"
which 3.0.1a handled quite nicely. Now 3.5 truncates the filename.
Is there any way to turn off the filename truncation? It's really nice
to do an ls and see which tests have been run without having to look in
each file. The data is processed on Suns, so I don't have to deal with
the name mapping on the pc's.
Any help would be appreciated.

I had this problem too. I called Sun and they supplied a patch to the pcnfs.sys file which disables this filename truncation. Here it is (hopefully it's cool to post a Sun suuplied patch....) ---------------------Sun supplied patch----------------------------- Here's a patch that reenables the bug so people can (usually) use long filenames and get away with it. Unfortunately because of serialization this must be done on each pcnfs.sys individually unless they have copyser: 1. Make a backup copy of pcnfs.sys. 2. Do the following, noting blank lines. At both addresses there should be "jz" instructions if you want to unassemble them first: ---------------- debug pcnfs.sys a a70d nop nop a a74f nop nop w q ---------------- 3. Reboot. ---------------------end Sun supplied patch------------------------- Hope this helps, Robert -- | Robert L.

I would also be very interested in disabling the filename truncation that version 3.5 does on MS-DOS filenames. Geoff - how about a switch in config.sys like the one that allows spaces in filenames?

You know those Peanuts cartoons where Charlie Brown is standing there with his mouth wide open screaming AAARGH! (in 36 point bold) while Lucy gazes at him innocently? That how this question made me feel.... Back in 85-86 when I designed the file name handling I decided (innocently) to be reasonably lax in what I let through, figuring that people would do the kinds of things these correspondents described, and why not let them. Then a year or two later along came a couple of apps which would sometimes open "averylongfilename" and sometimes "averylon" (probably depending on some library code) and would expect the same file to be opened. "After all," it was pointed out, "that's what happens under DOS, and on Novell, and...." So in 3.5 we "fixed" it, and promptly broke several other applications. Hence my Charlie Brown expletive. Anyway, I'm going to formalize the patch described in the last article into a configuration switch, or something like that. But be warned, the default behaviour will be DOS-like (unless Microsoft changes the rules.....) Geoff -- Geoff Arnold, PC-NFS architect, Sun Microsystems.
