thanks for the tip. access is a very simple function. it doesn't do the right thing, but there's a reason:

     BUGS
          Since file permissions are checked by the server and group
          information is not known to the client, access must open the
          file to check permissions.  (It calls stat(2) to check sim-
          ple existence.)

it's open() which is failing. i suppose it should.

if the open fails, maybe access should stat the file, and if it's a directory, try dirread(2). or maybe just opening it for reading will work. i don't know, i'm new to this bit of plan 9 & i haven't slept.
