Any ideas what would cause this--or what I should look for? Only one cube does it. rusers (with no arguments) dies with an IOT Trap, but works fine when given a hostname. NFS mounts also die with IOT Trap. My guess is there's a "this can't ever happen" abort() somewhere (in the RPC code?). I'm stymied. -=EPS=-

I'm not a NeXT expert, but I'm familiar with the Sun RPC library. abort() is called within auth_unix_create_default() if the getgroups() call returns -1. This will occur if the RPC library called getgroups(ngroups, ...) with a value of ngroups smaller than the kernel value (i.e. if the library was compiled with NGRPS set to 8 but the kernel thinks that NGROUPS is larger, say, 16 or 32. -- Steve Dyer dyer@ursa-major.spdcc.com aka {ima,harvard,rayssd,linus,m2c}!spdcc!dyer dyer@arktouros.mit.edu, dyer@hstbme.mit.edu

But I want to cross mount /usr/local back to the other cube (the one with NextLibrary) but no dice. The question is why can I mount from one to the other but then not vice versia. Also the only way I can get the mount to work is at boot time whenever I mount -a or mount /usr/local jeckle:/usr/local I get IOT trap (hmm I don't know) I think all the file are correct. because we also mount user space from our sun cluster. <><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><> <> :-{ :-\<> Russell Cattelan University of Minnesota <> <> :-} :-`) <> cattelan@umn-cs.cs.umn.edu <> <> :-) :-( <> {...!rutgers!umn-cs!cattelan} <> <><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>
