Description Daniel Black (RETIRED) gentoo-dev 2004-06-24 23:40:11 UTC
Steps:

1. emerge net-fs/samba
[ebuild   R   ] net-fs/samba-3.0.4-r1  +acl +cups +doc -kerberos -ldap -mysql +oav +pam -postgres -python +readline -xml -xml2  0 kB

2. Setup smb.conf (attachment 1 [details]) - very similar to ref URL
 - note fixed: vfs object = /usr/lib/vfs/vscan-clamav.so
3. Add /etc/samba/vscan-clamav.conf (as per ref URL except I did a quarantine option for infected files)

Commenting out the vfs options works fine.

Comment 2 Christian Andreetta (RETIRED) gentoo-dev 2004-07-15 05:15:44 UTC
strange: "vfs options" was officially removed from configuration options during the latest releases of samba-3.0.x. But this should not give the error NT_STATUS_BAD_NETWORK_NAME: could you try to compile with minimal CFLAGS? like -O1, or so: there are similar issues on ppc{32,64} and sparc that could be solved lowering compilation flags.
Comment 3 Christian Andreetta (RETIRED) gentoo-dev 2004-07-24 02:48:07 UTC
if you have time to spare, can you try samba-3.0.5-r1? Libs change: from /usr/lib/vfs to /usr/lib/samba/vfs. Compiler flags lowering.
I'm opening a forum on its refinig on bug #58090
Comment 4 Daniel Black (RETIRED) gentoo-dev 2004-07-24 06:32:43 UTC
Starting to think this bug is INVALID. In step 2 I've put a full path on /usr/lib.... The gentoo URL (and man 5 smb.conf etc...) all suggest that only "vfs object = vscan-clamav" is needed. I've changed to the right way and the vfs clamav seems to be initialising itself. And no errors.

Sorry for the confusion.

I'm not convinced "vfs options" is removed. Looking at /usr/share/doc/samba-3.0.5-r1/WHATSNEW.txt.gz

Line 1514 says its removed.
Line 1567 says its added in version 3.
Its still in the documentation http://au1.samba.org/samba/docs/man/smb.conf.5.html

That and it works.
