oh my.. heh, i think the 'ps' command seg faulted on me.. that was ever it.. i
have a 3/80 with 16 megs of ram and am attempting to use a 200 meg scsi-2 hd in
it.. haven't had much time for it as of late tho.. i don't have a monitor or
keyboard for the thing so i mess with the thing completely remote..

it almost looks as if there's an incorrect setup on the openbsd box...

right. in order to mount things at this point in the game, you must do it
manually like you did.

hrm, truely odd.. I think the versions i'm using are a bit newer than those
(from july/early august i believe) as I had some sort of problems with the older
versions (pardon me as i just woke up, my brain is in the fog, and i do not
remember the exact nature of the problems, suffice to say they pissed me off :) )
perhaps you should locate the latest versions of the kernel and filesystems and try
those out.. the 3/80 can be quite hairy at times and, from experience, newer
versions of kernels and whatnot tend to be less hairy than older versions (even
with a week's difference)

personally, i've never used openbsd. i boot mine from a linux box. however i
just might have to install openbsd on one of these puters someday...

there shouldn't be, altho i'm not entirely sure why you have 2 swap files.. one
should be all you need and it shouldn't be located in the root directory on the
nfs server side or perhaps that wouldn't matter.. so have either
/export/client/swap OR /export/client/root/swap but not both.. might want to experiment with
both and see what you get..

> 3. Hardware problems?

i doubt that there is any real hardware problem in this case... it sounds more
like the nfs server is either incorrectly setup and/or the kernel and filesystem
are not quite up to snuff.. another thing to keep in mind: the sun 3/80 is
considered a sun3x machine, not a sun3 because of the difference of the cpu and
whatnot ( 68030 w/ 68882 as opposed to a 68020 w/ 68881) so probably the best advice
I can give you in this situation is to find the _latest_ 3x kernels and
filesystems and go from there.
