Hello,
When I do:
% setenv KRBGTKFILE /tmp/tkt_foo
% kinit otheruser
MIT Project Athena ()
Kerberos Initialization for "otheruser"
Password: <password>
% attach otheruser
otheruser: NFS mounted SERVER.MIT.EDU:/mit/otheruser on
/mit/otheruser (read-write)
Error while subscribing: SERVNAK received /* What's this problem ? */
% cd /mit/otheruser
I am allowed to write that users files, but not read them. For
example:
% cd /mit/otheruser
% echo "foo" >foofile
% cat foofile
foofile: Permission denied
% chmod 644 foofile
% cat foofile
foo
%
This assumes that the users directory is world readable. This
seems slightly strange. If the NFS server accepts you as being who your
tickets say you are enough to write, why can't you read. Are read and
write authentications done differently?
Thanks,
Dave Morrison
