I performed further testing and noticed that: If I restart clamdscan and then smb everything seems to work. For example, if I try to open eicar.com (test virus), it detects malware and removes it. I can then easily open xls, doc, etc. files. Everything is correct. However, after a few minutes of use, for no apparent reason, I get this in the smb logs: Apr 27 15:26:24 X smbd_audit: [2021/04/27 15:26:24.216663, 0, pid=14938] ../../source3/modules/vfs_virusfilter_clamav.c:59(virusfilter_clamav_scan_init) Apr 27 15:26:24 X smbd_audit: virusfilter_clamav_scan_init: clamd: Connecting to socket failed: #020؆U: Aucun fichier ou dossier de ce type Apr 27 15:26:24 X smbd_audit: [2021/04/27 15:26:24.216843, 0, pid=14938] ../../source3/modules/vfs_virusfilter.c:1095(virusfilter_scan) Apr 27 15:26:24 X smbd_audit: virusfilter_scan: Scan result: Error: /data/smb2/00-Projets/ldap.xlsx: Initializing scanner failed Apr 27 15:26:24 X smbd_audit: zami3l | xx.xxx.xxx.xxx | public NETWORK|pread_recv|ok|/data/smb2/00-Projets/ldap.xlsx Apr 27 15:26:24 X smbd_audit: [2021/04/27 15:26:24.902581, 0, pid=14938] ../../source3/modules/vfs_virusfilter_clamav.c:59(virusfilter_clamav_scan_init) Apr 27 15:26:24 X smbd_audit: virusfilter_clamav_scan_init: clamd: Connecting to socket failed: #020؆U: Aucun fichier ou dossier de ce type Apr 27 15:26:24 X smbd_audit: [2021/04/27 15:26:24.902705, 0, pid=14938] ../../source3/modules/vfs_virusfilter.c:1095(virusfilter_scan) Apr 27 15:26:24 X smbd_audit: virusfilter_scan: Scan result: Error: /data/smb2/00-Projets/ldap.xlsx: Initializing scanner failed Apr 27 15:26:24 X smbd_audit: [2021/04/27 15:26:24.907650, 0, pid=14938] ../../source3/modules/vfs_virusfilter_clamav.c:59(virusfilter_clamav_scan_init) Apr 27 15:26:24 X smbd_audit: virusfilter_clamav_scan_init: clamd: Connecting to socket failed: #020؆U: Aucun fichier ou dossier de ce type Apr 27 15:26:24 X smbd_audit: [2021/04/27 15:26:24.907749, 0, pid=14938] ../../source3/modules/vfs_virusfilter.c:1095(virusfilter_scan) Apr 27 15:26:24 X smbd_audit: virusfilter_scan: Scan result: Error: /data/smb2/00-Projets/ldap.xlsx: Initializing scanner failed Apr 27 15:26:24 X smbd_audit: zami3l | xx.xxx.xxx.xxx | public NETWORK|pread_recv|ok|/data/smb2/00-Projets/ldap.xlsx Apr 27 15:26:24 X smbd_audit: [2021/04/27 15:26:24.939625, 0, pid=14938] ../../source3/modules/vfs_virusfilter_clamav.c:59(virusfilter_clamav_scan_init) Apr 27 15:26:24 X smbd_audit: virusfilter_clamav_scan_init: clamd: Connecting to socket failed: #020؆U: Aucun fichier ou dossier de ce type Apr 27 15:26:24 X smbd_audit: [2021/04/27 15:26:24.939732, 0, pid=14938] ../../source3/modules/vfs_virusfilter.c:1095(virusfilter_scan) Apr 27 15:26:24 X smbd_audit: virusfilter_scan: Scan result: Error: /data/smb2/00-Projets/ldap.xlsx: Initializing scanner failed After that, nothing works anymore. I am then forced to restart smb. So the problem seems to become with samba and vfs_virusfilter..... Thank you for answer.
