Subject: RE: Soft Links ON NT ( again) Mark,
I've got a quota tree on my F520 called "sandbox". My F520 system name is "tap", mainly because I got fed up of typing in "netapp" all the time. Anyway, what I'm trying to do is to get soft links with absolute path names to work on NT. They work fine on Unix(as you woud expect). I've installed SecureShare on all my PCs and am using Unix-style security on "sandbox" and indeed as the default security style on all other trees.
I use NIS on my LAN. "sandbox" on "tap" is accessed on Unix as /eeg/sandbox-the NIS map is called auto.eeg and has this line in it :
sandbox -intr tap:/sandbox
So, on Unix, all I have to do is
# cd /eeg/sandbox
and I'm there. Hard links (ln file linkname) work fine on NT, as do relative soft links ( ln -s ../file linkname). The problem I'm having is with soft links with absolute path names on NT. If, for example, I do # cd /eeg/sandbox/dir2 # ln -s /eeg/sandbox/dir1/file linkname
NT can't seem to access linkname on /eeg/sandbox/dir2 at all, apart from showing it in the Windows Explorer. I hope this is clear.
My /etc/symlink.translations file looks like this :
Map /sandbox/* //sandbox/*
The double slash on the second field is to counteract Bud ID 9553, which I found on the NOW website. Also, I've tried terminating and restarting CIFS, but without success.
Thanks for any help you can give me.
I think I know why the NT box is having problems, and I think I can demonstrate a similar situation on two Unix boxes.
Simply put, absolute symlinks have too much information, they're too precise for either the NT box or the filer to map them correctly.
To demonstrate my hypothetical scenario, I've use my home directory on ukwfs2 another F520 (running 4.3.1, for interest).
On our (SunOS4.1.4) admin host:
uk-dns-stv1-root /net/ukwfs2/users/d23/mds46523: ln -s \ /net/ukwfs2/users/d23/mds46523/dead.letter flibble
uk-dns-stv1-root /net/ukwfs2/users/d23/mds46523: ln -s ./dead.letter flobble
Creating two symlinks in my home directory to a simple text-file also in the directory, one absolute, one relative.
Now, on a client, in my home directory:
0 ukwit12> head -2 flibble UX:head: ERROR: Cannot read from flibble 1 ukwit12> head -2 flobble

The absolute symlink simply overspecifies the location, which my client has no way to map to something it can understand and use.
The NT box is in as bad a position as my Unix client - the /eeg/... part of any absolute symlink in your Unix domain doesn't match anything in the NT box's wordlview, and the filer has no rule to map it for the NT box.
Extend the mapping rules in the filer, or revert all absolute symlinks to relative symlinks and I think you'll be able to work around the problem.
I'd try adding:
Map /eeg/sandbox/* //sandbox/*
to your /etc/symlink.translations file.

Send me a copy of your symlink.translations file, along with a specific description of what you are trying to do, and I'll try to help get you going.
One thing that may not be documented clearly is that you have to restart cifs before the symlink.translations file is reloaded. Yes, it's a bug.

Mark,
Now, I can see the permissions via SecureShare, but still can't read or edit the file. Here is what the /etc/symlink.translations file now looks like :
cat symlink.translations Map /eeg/sandbox/* //sandbox/*
Here is what a long listing looks like on Unix :
{dv40ss5::raybr} [10] % l total 2 drwxrwsr-x 2 raybr eeg 4096 Sep 22 16:21 . drwxr-sr-x 6 raybr eeg 4096 Sep 22 14:01 .. lrwxrwxrwx 1 raybr eeg 25 Sep 22 15:19 absolutesoftlink -> /eeg/sandbox/raybr/1/test -rw-rw-r-- 2 raybr eeg 6 Sep 22 14:03 hardlink lrwxrwxrwx 1 raybr eeg 9 Sep 22 15:18 relativesoftlink -> ../1/test {dv40ss5::raybr} [11] %
The file I want to be able to access is absolutesoftlink. if I try to send it to a text editor, I get :
Access is denied.
I have stopped and restarted CIFS as you said. So, what do I do now ?
:(
