VFSTEST(1)VFSTEST(1)NAMEvfstest - tool for testing samba VFS modules
SYNOPSISvfstest [-d debuglevel] [-c command] [-l logdir] [-h]
This tool is part of the samba(7) suite.
vfstest is a small command line utility that has the ability to test
dso samba VFS modules. It gives the user the ability to call the vari‐
ous VFS functions manually and supports cascaded VFS modules.
Execute the specified (colon-separated) commands. See below for
the commands that are available.
Print a summary of command line options.
File name for log/debug files. The extension'.client' will be
appended. The log file is never removed by the client.
-V Prints the program version number.
-s <configuration file>
The file specified contains the configuration details required
by the server. The information in this file includes server-spe‐
cific information such as what printcap file to use, as well as
descriptions of all the services that the server is to provide.
See smb.conf for more information. The default configuration
file name is determined at compile time.
debuglevel is an integer from 0 to 10. The default value if this
parameter is not specified is zero.
The higher this value, the more detail will be logged to the log
files about the activities of the server. At level 0, only crit‐
ical errors and serious warnings will be logged. Level 1 is a
reasonable level for day-to-day running - it generates a small
amount of information about operations carried out.
Levels above 1 will generate considerable amounts of log data,
and should only be used when investigating a problem. Levels
above 3 are designed for use only by developers and generate
HUGE amounts of log data, most of which is extremely cryptic.
Note that specifying this parameter here will override the pa‐
rameter in the smb.conf file.
Base directory name for log/debug files. The extension ".prog‐
name" will be appended (e.g. log.smbclient, log.smbd, etc...).
The log file is never removed by the client.

This man page is correct for version 3.0 of the Samba suite.
The original Samba software and related utilities were created by An‐
drew Tridgell. Samba is now developed by the Samba Team as an Open
Source project similar to the way the Linux kernel is developed.
The vfstest man page was written by Jelmer Vernooij.
