su - zimbra cd clamav-unofficial-sigs wget https://github.com/extremeshok/clamav-unofficial-sigs/archive/4.9.2.tar.gz -O clamav-unofficial-sigs_4.9.2.tar.gz tar --strip-components=1 -xf clamav-unofficial-sigs_4.9.2.tar.gz
Editez le fichier clamav-unofficial-sigs.conf
:
clam_user="zimbra" clam_group="zimbra" clam_dbs="/opt/zimbra/data/clamav/db" clamd_pid="/opt/zimbra/log/clamd.pid" work_dir="/opt/zimbra/clamav-unofficial-sigs/unofficial-dbs" user_configuration_complete=”yes“
Ajoutez en début du fichier clamav-unofficial-sigs.conf
:
PATH="/opt/zimbra/bin:/opt/zimbra/postfix/sbin:/opt/zimbra/openldap/bin:/opt/zimbra/snmp/bin:/opt/zimbra/rsync/bin:/opt/zimbra/bdb/bin:/opt/zimbra/openssl/bin:/opt/zimbra/java/bin:/usr/sbin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/opt/zimbra/clamav/bin:/opt/zimbra/clamav/sbin"
Appliquez ce petit patch (fixé sur git)

chmod +x clamav-unofficial-sigs.sh ./clamav-unofficial-sigs.sh -c ./clamav-unofficial-sigs.conf
Vous devriez voir les nouvelles databases dans la bdd clamav de zimbra :
ls -al /opt/zimbra/data/clamav/db
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.sh -c /opt/zimbra/clamav-unofficial-sigs/clamav-unofficial-sigs.conf > /dev/null
Et pour terminer, on copie le script logrotate :
/opt/zimbra/clamav-unofficial-sigs/clamav-unofficial-sigs-logrotate /etc/logrotate.d/
Modifiez la ligne create 0644 clam clam
par create 0644 zimbra zimbra
