All of this may be true, the .rhost file must be world-readable if root
has to access it as "nobody" across nfs. However, the problem as we
occasionally see it here is somewhat different.
In our case, rlogin works fine most of the time. There are occasions,
though, where it will anomalously request a password. On those occasions,
if we supply a password and log in, we find that the mode 644 .rhost file
shows up in an "ls -la" but it is not accessible. "cat" gives a write(?)
error if you try to examine the file. "mv"ing it to a new name makes it
possible to look at the file, and it is still accessible after being moved
back to the original name.
This only happens occasionally, and we haven't been able to explain it.
