My tokens had just expired in a fascist directory:
811% ls
afs: Tokens for user of AFS id 14640 have expired
notes not found (Permission denied)
proto.tex not found (Permission denied)
sample.tex not found (Permission denied)
RCS not found (Permission denied)
./ Makefile thesis.PS thesis.dvi thesis.tex
../ lmac.aux thesis.aux thesis.log thesis.toc
<cronos!probe> {~/thesis}
812% ls
notes not found (Permission denied)
proto.tex not found (Permission denied)
sample.tex not found (Permission denied)
RCS not found (Permission denied)
./ Makefile thesis.PS thesis.dvi thesis.tex
../ lmac.aux thesis.aux thesis.log thesis.toc
<cronos!probe> {~/thesis}
813% fs la
Access list for . is
Normal rights:
probe:thesis rl
probe rlidwka
<cronos!probe> {~/thesis}
814%
As you can see, I had no right to see anything with expired tokens...
The other thing that happened after a couple attempts was that I got the
following console message:
xdr_bytes: size FAILED
The inconsistent behavior seen in the above example can be described by
them being in the AFS cache, but it should probably do some more sanity
checking than it just did...
