Thanks for all your help.  With the patch from Carsten and Simon I have
successfully compiled and started AFS.

Re: [OpenAFS] kopenafs.h and libkopenafs question on status

[mike coyne]

For some background , the version of globus we are using is from the VDT
distibution http://vdt.cs.wisc.edu/  , This a prepackaged globus 4.0.8
as patched by vdt from various sources.
http://vdt.cs.wisc.edu/software/globus/4.0.8_VDT-1.10.1/globus-patched-source.tar.gz
 is the source from vdt.

My Initial problems with the gatekeeper was that using the external
shell service with globus_k5 ( i believe orignaly written to shell out
and get a kerberos token in from gram ), the call to gssklog -setpag
didn't work as the lsetpag function can't change its parent process at
least for linux. So i setout to add a call to lsetpag in globus_k5 prior
to execv 'ing the call to "gssklog" described in its private mapfile.

in had a similar problem in the globus-gridftp-server , int the
globus_i_gridftp_server.c i added some calls to save the current creds,
do a lsetpag, shell a call to gssklog , and the unlink the credintial
cache so a user could do a globus-url-copy to there home directory in
afs. 

then for wsgram i added the lsetpag and shell to gssklog into the
globus_gridmap_and_execute .c source so that when web stuff fires off
sudo to switch and run as a user, calling globus_gridmap_and_execute
inline so it get their afs token in a new pag in the process and
verifies there creds in the gridmapfile. 

I probably went about this the hard way but so far it seems to work.

It should actually be in a 1.5 release very soon, I conferred with
Russ this morning on the way
to the workshop and it looks like the efforts to make updates appear
at the same time we convert to git for version
control will bring this along.

I have not been involved with Globus for years, but wrote gsiklog and then
gssklog and much of the Globus gatekeeper for Globus version 1.1.3. The intent
was for the gatekeeper to call gssklog to get a PAG and token, and it should

then that requires you have to redo the code.

I noticed

“features” versions? It appears to be maintained since abut 2006 and 
would be quit usefull it will be available .



To refraze  the question I have calling lsetpag() after some stats on 
the /afs directory to see if its there.


The original gssklog provided a version of lsetpag in gafstoken.c that
trapped signals if the AFS syscall failed, i.e. AFS was not present on
the machine. Thus it dod not need any AFS libraries. This was long before
k_hasafs which might be a beter choice.

 And hard linking In lilbsys.a
 but if the prefered  interface is  k_hasafs() and k_setpag() should I 
switch.

That's the long-term intention, but I don't think we've decided what
version of OpenAFS that library will start shipping with yet.  The goal
is to ship it as a shared library with a stable API, which avoids
various problems with trying to link to libsys.

Re: [OpenAFS] Clean Uninstall of OpenAFS for Windows and krb5 ?

[Jeffrey Altman]

If you have a problem, re-installing is unlikely to resolve it.
I would suggest that you describe the problem you are having
and ask for assistance with how to remove the registry keys
that are documented in the Release Notes that are installed on
the machine with the client.

configuration data is not removed because it is considered
to be owned by the user/organization and is version independent.

[OpenAFS] Clean Uninstall of OpenAFS for Windows and krb5 ?

[Claudio Prono]

Hi to all,

How i can do a clean uninstall of openafs for windows and krb5? I have
uninstalled them, but i can notice there are some things don't be
removed. When i reinstall some config are the same as before, so the
uninstall is not completely clean... I have some problem on a PC and
with a simple uninstall - reinstall i can't resolve it.

Any hint ?

Claudio.

[OpenAFS] TSM backup client

[Anders Magnusson]

So, at last the TSM client I have written is available.  It can be fetched
from /afs/ltu.se/misc/tsmafs/tsmafs-0.1.tgz for anyone that is interested.

Simple overview:
The backup client works by talking directly to the file server(s) and 
fetch files
out of afs, and then put them into tsm as separate objects (as other tsm 
backup
clients do).  In this way it works with the usual policies setup for tsm 
regarding

storage time, object counts etc.
Backups are done volume-wise.  Mountpoints and ACLs are stored as they
should be.  Volumes are checked if changed before traversing them, which
speed up the process significantly.

The restore client works but should need a facelift.  Currently it just 
restores

files and directories without possibility to change time or so.  Do do more
advanced restore stuff, use dsmc, it can restore files backed up from afs
(but no acls or so then).

The only "flaw" is that the TSM API cannot handle names with ? or * in it,
so I do a little name mangling here: \ -> \\, * -> \# and ? -? \!.  This 
could

easily be converted back via the restore client, but not yet added.

Comments/ideas/fixes?

 Hello,

I'm running openafs-1.4.10 on a i386 FreeBSD 7.2-RELEASE-p0
Here is the patch to compile :
http://www.arcadebsd.org/~elbarto/patch_fbsd-72.diff
The patch include the modification needed for an amd64 environment but it
isn't tested.

I got a few problems :

- I have to specified the --with-bsd-kernel-headers and
--with-bsd-kernel-build, it won't compile with the default value (I, maybe,
have forgotten to modify some autotool config files).
- When browsing a big directory with Thunar (the xfce file manager) the
computer freeze and I can't get a coredump of afsd or a savecore of the
kernel to help debugging.
- I think I tested in the past some user with home directory on afs and the
kernel panic at link or unlink syscall, I will re-test that in a few days.

Hope it can help some people to debug/run openafs on FreeBSD.

Cheers.
