VFS_FULL_AUDIT(8)

💖 VFS_FULL_AUDIT 💖

okay bestie, sit DOWN, because this is vfs_full_audit from the samba(7) suite and it's literally the "record everything" girlie of the Samba VFS world. manual section 8, system administration tools, and yes she's iconic for it. 👑

✨ NAME ✨

vfs_full_audit — record Samba VFS operations in the system log 🫶

---

🌸 SYNOPSIS 🌸

vfs objects = full_audit

that's it. that's the whole vibe. one line. slay.

---

🦋 DESCRIPTION 🦋

okay so first thing, this VFS module is part of the samba(7) suite. family reunion energy. 🌈

The vfs_full_audit VFS module records selected client operations to the system log using syslog(3). yes, syslog. old school and unbothered. 💅

and the way she can log the complete set of Samba VFS operations? no cap, the whole roster:

like, the whole entire list. obsessed. 💖

In addition to all of those, vfs_full_audit also recognizes two special operation names: all and none — and those two cuties mean all the VFS operations and none of the VFS operations respectively. main character shortcuts fr fr.

now, real talk for a sec because this part MATTERS 😭 — if an unknown operation name gets used (say somebody miss-spelled an operation name), the module will fail to load and clients will be refused connections to a share using this module. so like, spell check your config, bestie. not a drill. 💀

vfs_full_audit records operations in a fixed format: fields separated by | characters. the format is:

smbd_audit: PREFIX|OPERATION|RESULT|FILE

and 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. 🧚 (yes queen, stack her with your other faves.)

---

💅 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 🌟

so like, log file and directory open operations on the [records] share using the LOCAL7 facility and ALERT priority, including the username and IP address — and logging excludes the open VFS function on failures. serve:

            [records]
         path = /data/records
         vfs objects = full_audit
         full_audit:prefix = %u|%I
         full_audit:success = open opendir
         full_audit:failure = all !open
         full_audit:facility = LOCAL7
         full_audit:priority = ALERT

ate that config. no crumbs. 🔥
