What were you trying to do?
Copy a file while preserving dates. The below example is
contained entirely within the athena.mit.edu cell for
simplicity's sake, though I originally encountered the problem
while copying from the iastate.edu
[1. I have a preexisting file in locker that I have ``all'' access
to; I have tokens and tickets and all that...]
athena% cat athena% fs la
Access list for . is
Normal rights:
system:expunge ld
system:anyuser l
jhawk rlidwka
athena% cat > inetd.conf
This is a test.
athena% ls -l inetd.conf
-rw------- 1 jhawk system 16 Oct 21 03:57 inetd.conf
[2. I attempt to copy a mode 444 file owned by another uid in it's place,
preserving the dates of the original file (cp -p)]
athena% ls -l /srvd
lrwxrwxrwx 1 root system 43 Oct 20 22:01 /srvd -> /afs/athena.mit.edu/system/rs_aix32/srvd.77
athena% ls -l /srv/etc/inetd.conf
/srv/etc/inetd.conf not found
athena% ls -l /srvd/etc/inetd.conf
-r--r--r-- 1 root sys 2326 Jul 08 10:02 /srvd/etc/inetd.conf
athena% cp -p /srvd/etc/inetd.conf inetd.conf
afs: failed to store file (access denied)
cp: inetd.conf: Permission denied
athena% ls -l inetd.conf
inetd.conf not found
athena%
What's wrong:
AFS should not have failed to store the file. Furthermore,
AFS should NOT have removed the preexisting file in the event
of such a failure.
What should have happened:
What do you think? It should have worked fine. It should be noted
that the desired behavior may be obtained with:
cp -p /srvd/etc/inetd.conf /tmp/inetd.conf
cp -p /tmp/inetd.conf inetd.conf
Please describe any relevant documentation references:
None. Common sense, Unix intuition, just us chickens.
