9/Stretch - Missing vscan-clamav.so in samba-vfs-modules

Butterbear · 07-03-2017, 03:50 AM

Hi,

I'm attempting to set up Samba shares with the vscan-clamav VFS module, but apparently when installing samba-vfs-modules, vscan-clamav.so is not included, and access to shares is denied with the following log entry:

Code:

Error loading module '/usr/lib/i386-linux-gnu/samba/vfs/vscan-clamav.so': /usr/lib/i386-linux-gnu/samba/vfs/vscan-clamav.so: cannot open shared object file: No such file or directory

/usr/lib/i386-linux-gnu/samba/vfs contains the following after installation:

Code:

I installed the following packages from the standard Debian repositories:

Code:

samba
smbclient
samba-vfs-modules
smbldap-tools
samba-common-bin
clamav
clamav-base
clamav-daemon
clamav-freshclam
clamdscan
libclamav-dev
libclamunrar7
clamav-unofficial-sigs
clamfs
clamtk
clamav-docs

I cannot find a clear answer on how to fix this in a way that doesn't break with an apt-get upgrade (and preferably avoids manual recompiles).

What did I miss?

Try:

Code:

$ locate vscan-clamav.so

to find out if it (or anything like it) exists anywhere on the system. If you find it, make a symlink to

Code:

/usr/lib/i386-linux-gnu/samba/vfs/vscan-clamav.so

If it's a 64-bit system you might have to try:

Code:

$ dpkg --add-architecture i386

and run

Code:

$ apt-get -f install

to bring in 32-bit dependencies.

Hi AwesomeMachine, thank you for replying.

locate was not installed, so I installed it:

Code:

bash: locate: command not found

I understand this requires a database, so:

Followed by:

Code:

root@fs01:/etc/samba#

Alas

This is not a 64-bit machine unfortunately, so I cannot try the other suggestion.
