Re[4]: [OpenAFS] permissions, symbolic links, ftp

[Ron Croonenberg]

I noticed something ....

When I cd to the root of the file system ("/") in ftp I end up in the user
directory /home/otheruser  when logged in as user.

when I try to cd to /home/user (or a link to /home/user) it says that file
doesn't exist. (amnd that is correct because it is trrying to cd to
/home/otheruser/home/user  and that doesn't exist.

So it looks like I can't go any higher (or is it lower) up the tree then the
homedirectory of the user I am logged into with ftp. When I  log in with a shell
I can go to the root of the filesystem and cd to another users directory.

question is, why  can I go to the root of the filesystem when I log in but I
can't when I log in with ftp.
Is that an AFS permissions thing ?  or is it an ftp thing ? (meaning ftp doesn't
even know there is anything below the users home directory ?)

thanks,

Ron
