Ajouter des signatures ClamAV dans zimbra 8.8

En root :

mkdir /opt/zimbra/clamav-unofficial-sigs
chown zimbra:zimbra /opt/zimbra/clamav-unofficial-sigs

En utilisateur zimbra :

su - zimbra
cd clamav-unofficial-sigs
wget https://github.com/extremeshok/clamav-unofficial-sigs/archive/5.6.2.tar.gz -O clamav-unofficial-sigs_5.6.2.tar.gz
tar -xf clamav-unofficial-sigs_5.6.2.tar.gz
ln -sf clamav-unofficial-sigs-5.6.2 clamav-unofficial-sigs
cd ..
mkdir conf/clamav-unofficial-sigs
mkdir data/clamav-unofficial-sigs
cp clamav-unofficial-sigs/clamav-unofficial-sigs/config/{master.conf,user.conf} conf/clamav-unofficial-sigs/

Créez le fihcier /opt/zimbra/conf/clamav-unofficial-sigs/os.conf contenant :

clam_user="zimbra"
clam_group="zimbra"
clam_dbs="/opt/zimbra/data/clamav/db"
clamd_pid="/opt/zimbra/log/clamd.pid"
work_dir="/opt/zimbra/data/clamav-unofficia-sigs"
log_file_path="/opt/zimbra/log"
clamd_reload_opt="/opt/zimbra/common/bin/clamdscan --config-file=/opt/zimbra/conf/clamd.conf --reload"
clamscan_bin="/opt/zimbra/common/bin/clamscan"
user_configuration_complete="yes"

Appliquez ce petit patch :

Lancez le une première fois (toujours avec l'utilisateur zimbra)

./clamav-unofficial-sigs/clamav-unofficial-sigs/clamav-unofficial-sigs/clamav-unofficial-sigs.sh -c conf/clamav-unofficial-sigs/

Enfin, nous allons ajouter un crontab mettant a jour la liste automatiquement. Tapez crontab -e puis ajoutez tout a la fin du fichier (juste après # ZIMBRAEND) :

45 * * * * /bin/bash /opt/zimbra/clamav-unofficial-sigs/clamav-unofficial-sigs/clamav-unofficial-sigs.sh -c /opt/zimbra/conf/clamav-unofficial-sigs > /dev/null

Et pour terminer, on copie le script logrotate :

cp /opt/zimbra/clamav-unofficial-sigs/clamav-unofficial-sigs-logrotate /etc/logrotate.d/

Modifiez la ligne create 0644 clam clam par create 0644 zimbra zimbra
