vfs_full_audit 8 Samba System Administration tools &doc.version; vfs_full_audit record Samba VFS operations in the system log vfs objects = full_audit DESCRIPTION This VFS module is part of the samba 7 suite. The vfs_full_audit VFS module records selected client operations to the system log using syslog 3. vfs_full_audit is able to record the complete set of Samba VFS operations: aio_force audit_file brl_lock_windows brl_unlock_windows chdir close closedir connect connectpath create_dfs_pathat create_file disconnect disk_free durable_cookie durable_disconnect durable_reconnect fallocate fchflags fchmod fchown fcntl fdopendir fget_compression fget_dos_attributes fget_nt_acl fgetxattr file_id_create filesystem_sharemode flistxattr fntimes freaddir_attr fremovexattr fs_capabilities fsctl fset_dos_attributes fset_nt_acl fsetxattr fs_file_id fstat fstatat fstreaminfo fsync_recv fsync_send ftruncate get_alloc_size get_dfs_referrals get_dos_attributes_recv get_dos_attributes_send getlock get_quota get_real_filename get_real_filename_at get_shadow_copy_data getwd getxattrat_recv getxattrat_send is_offline lchown linkat linux_setlease lock lseek lstat mkdirat mknodat ntimes offload_read_recv offload_read_send offload_write_recv offload_write_send open openat parent_pathname pread pread_recv pread_send pwrite pwrite_recv pwrite_send read read_dfs_pathat readdir readlinkat realpath recvfile removexattr renameat rewinddir sendfile set_compression set_offline set_quota snap_check_path snap_create snap_delete stat statvfs strict_lock_check symlinkat sys_acl_blob_get_fd sys_acl_delete_def_fd sys_acl_get_fd sys_acl_set_fd translate_name unlinkat write In addition to these operations, vfs_full_audit recognizes the special operation names "all" and "none ", which refer to all the VFS operations and none of the VFS operations respectively. If an unknown operation name is used (for example an operation name is miss-spelled), the module will fail to load and clients will be refused connections to a share using this module. vfs_full_audit records operations in fixed format consisting of fields separated by '|' characters. The format is: smbd_audit: PREFIX|OPERATION|RESULT|FILE The record fields are: PREFIX - the result of the full_audit:prefix string after variable substitutions OPERATION - the name of the VFS operation RESULT - whether the operation succeeded or failed FILE - the name of the file or directory the operation was performed on This module is stackable. OPTIONS full_audit:prefix = STRING Prepend audit messages with STRING. STRING is processed for standard substitution variables listed in smb.conf 5. The default prefix is "%u|%I". full_audit:success = LIST LIST is a list of VFS operations that should be recorded if they succeed. Operations are specified using the names listed above. Operations can be unset by prefixing the names with "!". The default is none operations. full_audit:failure = LIST LIST is a list of VFS operations that should be recorded if they failed. Operations are specified using the names listed above. Operations can be unset by prefixing the names with "!". The default is none operations. full_audit:facility = FACILITY Log messages to the named syslog 3 facility. full_audit:priority = PRIORITY Log messages with the named syslog 3 priority. full_audit:syslog = true/false Log messages to syslog (default) or as a debug level 1 message. full_audit:log_secdesc = true/false Log an sddl form of the security descriptor coming in when a client sets an acl. Defaults to false. EXAMPLES Log file and directory open operations on the [records] share using the LOCAL7 facility and ALERT priority, including the username and IP address. Logging excludes the open VFS function on failures: /data/records full_audit %u|%I open opendir all !open LOCAL7 ALERT VERSION This man page is part of version &doc.version; of the Samba suite. AUTHOR The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed.
