Martin,  I agree that it'd be nice to have something that'll work with
all these environments.

The browse/mount interface is taken care of pretty well with
gnome-vfs2.  I'm unclear on how much space bringing in gnome-vfs2
requires (there's nothing graphical about it directly).

What would you suggest that we could start with?  I'm open.

Right now, all of the graphical file browsers have some of their own
way to represent icons (typically depedening on the file type).  That
should work right now with any graphical file manager you use on top
of afpfs-ng mounts.

One of the tricks of the finder is the ability to change the icon,
comment or application of a given file.  This is set in the resource
fork for the file.  I'd like a Linux client to be able to interpret
and display those.

Is the guest login working in 0.2 ? I tried with that release also but
couldn't login to the server.

Not to say it's a bad way. If you feel comfortable with nautilus thats o=
k.
For me its over 200MB extra install for something I don't want, and if
you use KDE it's the same thing.

It's good if the base is as independent as possible so implementations
for different environments can be done small and easy.

Different environment could be for example Gnome, KDE, XFCE or terminal.=

I don't realy understand the thing with icons? Isn't it good with icons

[Afpfs-ng-devel] A more complete AFP client

[Alex d. <ale...@gm...>]

Martin Forsgren and I were having a side conversation, and I thought
I'd open the topic up to the whole list.

My goal is, ultimately, to make a finder for Linux.  afpfs-ng is just
one part of this.  There's a few different ways to do it, and I'm
thinking that I'd like to do this with gnome and nautilus.  But
there's certainly room for other implementations.

1. A browser

I think you get this with avahi-browse.

2. A gnome-vfs2 module

This would be able to handle afp:// URIs, and would be a wrapper
around afp_client, and talk directly to the mounted filesystem.

3. A nautilus extension

I'm not quite sure what kind of extension this is (I think maybe a
NautilusView), but it would be able to parse the meta information that
afpfs-ng presents as hidden files to the user.

In afpfs-ng (starting in 0.4, it was broken in 0.3),  the resource
fork for /foo/bar is in foo/bar/rsrc.  (for AFP 2.x, comments, APPLs
and icons will also available, but those are not the current focus).

With the help of a resource parsing library, you can dig up icons and
other strings related to any given file and represent them accordingly
in nautilus.  I spent a weekend writing the parser that extracts icons
from the resource fork, I had a problem finding any reasonable code
out there.

It took me some time to find anything to help remap the icons to PNG
files, that'll be another task.  We'd have to somehow map the various
sizes of icons to the ones that nautilus expects, and I can see that
being a bit painful.

So, that's my general plan.  What's yours?

Re: [Afpfs-ng-devel] Login as Guest

[Alex d. <ale...@gm...>]

Sharminder,

Yes, guest access is broken in 0.3, so the only way to use it as it is
is to setup a fake user and fake password on the server and to use
'afp_client mount -u fakeuser -p fakepass server:volume /mntpoint'

If you really can't make the above changes to the server, let me know
and I can probably come up with a patch for 0.3.

It'll be fixed in 0.4, but I'm still busy with the overhaul of
threading to handle unmount cleanly.

Let me know how that goes.

Re: [Afpfs-ng-devel] Segment fault

[Alex d. <ale...@gm...>]

Martin,

Ah.  It looks like I inadvertantly broke the UAM selection code in 0.3
and it'll now only work with cleartext passwords.  Could you try this
using by using uams_clrtxt.so instead of uams_guest.so?

You'll then have to use:
afp_client mount -u myuser -p mypass MtheF:media tmp/

BTW, I see you were using just "-p villin".  There's a bug in that
afp_client should have given you a warning that the password would be
ignored.

Let me know if you could use clrtxt, if not, I might be able to come
up with a patch to 0.3 that fixes this.

I happen to have redone the UAM code this morning for 0.4, but it'll
be a few weeks before I can release that.  One of the big fixes in 0.4
is proper error recovery when a server goes down or crashes and to
handle unmount cleanly, so I'm trying to simplify the threading to
support this.  It's a bit complicated, but it is starting to work.

Tack s=E5 mycket,

- Alex

Dear Admin,

    I setup a netatalk 2.0.3 on a redhat linux ES 4 (2.6.17.8) .

    When a Mac user create a folder or file on the Volume, it add the sticky
bit automatic.

    Could you please tell how to disable function ? I do not need the sticky
bit on this file or folder .

    Thank you very  much.

Thanks!

[Afpfs-ng-devel] Announcing afpfs-ng 0.3

[Alex d. <ale...@gm...>]

What is new in 0.3, Nov. 27, 2006
---------------------------------
* many, many memory leaks fixed with some help from valgrind and close
inspection
* fixed many segfaults from null pointer dereferencing
* heap corruption fixed
* server version matching works now (afpfs-ng speaks 3.2 by default)
* more testing against 10.2, 10.3 and 10.4 and netatalk
* some documentation
* preliminary support for resource forks (although this is still
incomplete and broken)

0.2 had a lot of problems with stability, mostly because of the
complex and optimized DSI read code, which does zero-copy reads and
handles quantums properly. This appears to be fixed now.

Please, if you've tried afpfs-ng, let me know.  You can subscribe to
the mailing list at http://sourceforge.net/projects/afpfs-ng, or mail
me at ale...@gm....

And from now on I'll stop spamming the netatalk list with these minor
version releases.

- Alex

Re: [Afpfs-ng-devel] Please check my RPMS.

[Alex d. <ale...@gm...>]

Houritsu,

Excellent, thanks.

The changes you had to make to get it to build are already in 0.3,
which will be out later today.

Have you actually tried running it?

[Afpfs-ng-devel] Accessing resource forks with hfsplus, netatalk and afpfs-ng

[Alex d. <ale...@gm...>]

In writing afpfs-ng, I've spent a bit of time looking at how to
represent resource forks on a unix-style filesystem.

>From what I gather, there's three open source projects that the same problem:
- netatalk, which stores them in .AppleDouble directories as appledouble files
- hfsplus, which I haven't figured out how it represents them
- afpfs-ng, which I'm trying to write correctly

I see a few reasons for trying to standardize on the format for this:

- you could potentially use netatalk to re-export a locally connected
HFS+ volume or re-export a remote AFP volume

- an extension to konqueror or nautilus so that they could look a bit
more like the Finder when looking at such filesystems

Has anyone looked at extending such a file browser to support these things?

[Afpfs-ng-devel] Announcing afpfs-ng 0.2

[Alex d. <ale...@gm...>]

I've just uploaded afpfs-ng-0.2, you can find it:
http://sourceforge.net/project/showfiles.php?group_id=179882

It's starting to look like a reasonable start to a client.

What is new in 0.2, Nov. 20, 2006
---------------------------------

In version 0.2, the project has matured considerably.  You can mount a volume,
see, read and write files with reasonable performance.

* much better testing against 10.3 and 10.4 (speaking AFP 3.1, not 3.2)
* better error handling
* restructured into client/server
* rewrote incoming reads to optimize for read performance.  It works!
* lots and lots of other changes
  - fixed rename, large dids, UTF8 namesA
* dynamic quantum calculation
* status
* new logging mechanism, forking
* autoconf (sigh)

[Afpfs-ng-devel] What's coming up with afpfs-ng

[Alex d. <ale...@gm...>]

afpfs-ng 0.1 has been out there for a few weeks, and I've gotten some
responses back from people, generally interested in the project and a
bit of testing.

Here's what's coming in 0.2.

The structure needs to change a bit so that we can support things like
password changing and efficient multiple volume mounting.  So I'm
going to make a daemon that handles all the AFP traffic (for multiple
servers and multiple mounts per server).   There'll also be a small
client that allows for various commands like password changing,
mounting, etc.

I'm also trying to fix the AFP 3.x writing problem.  I know I've never
seen it work, but I believe that others have.  I'm a bit short on
equipment, so I haven't been able to get a packet trace of a file
write over AFP 3.x, all my work's been done with netatalk.

So if anyone has such an environment, that'd be appreciated.  Now that
my wife has her macbook, I should get her old ibook, thus giving me
two afp 3.x machines.  Then when I also get my ethernet hub (not
switch), I should also be able to do some testing with macos 9.

Also coming is a way to represent resource fork data and icons as
Linux files in a similiar way to how HFS+ works.  I've only read about
it, I haven't actually used it.  But that's coming.

Feel free to join in any capacity that you can...
