Hello,

since I got a mail from another person who had this same problem, I would l=
ike=20
to follow up on this. Here's what I wrote back in august:

The problem seems to be independent of the server(s) or cell, because it al=
so=20
happens when I try to access public cells on the internet, running complete=
ly=20
unauthenticated, like:

heini@gondolin ~ % LANG=3D"" ll /afs/grand.central.org/
ls: cannot access /afs/grand.central.org/local: No such file or directory
ls: cannot access /afs/grand.central.org/software: No such file or directory
total 14K
drwxrwxrwx 3 root root 2.0K Jun 17  2004 archive/
drwxrwxrwx 2 root root 2.0K May  7  2006 cvs/
drwxrwxrwx 3 root root 2.0K Mar 21  2003 doc/
?????????? ? ?    ?       ?            ? local
drwxrwxrwx 2 root root 2.0K Jun 17  2005 project/
drwxrwxrwx 5 root root 2.0K Jan 30  2007 service/
?????????? ? ?    ?       ?            ? software
drwxrwxrwx 2 root root 2.0K Aug 25 00:15 user/
drwxrwxrwx 5 root root 2.0K Aug 24 20:10 www/

The client has been started like this:

/usr/sbin/afsd -fakestat -stat 2000 -dcache 800 -daemons 3 -volumes=20
70 -verbose -debug -dynroot

Which, except for -verbose and -debug, is the default I get from the Gentoo=
=20
init script, which sets the values based on the cache size.

Version info:

Kernel: Vanilla 2.6.22.7
OpenAFS: Gentoo Package openafs-kernel-1.4.4_p20070724-r2

Bye...
