# vfstest - Unix, Linux Command

# NAME

vfstest - tool for testing samba VFS modules

# SYNOPSIS

Tag | Description
--- | ---
vfstest [-d debuglevel] [-c command] [-l logdir] [-h]

# DESCRIPTION

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 various VFS functions manually and supports cascaded VFS modules.

# OPTIONS

-c|--command=command Execute the specified (colon-separated) commands. See below for the commands that are available.

-h|--help Print a summary of command line options.

-l|--logfile=logbasename File name for log/debug files. The extension '.client' will be appended. The log file is never removed by the client.

-d|--debuglevel=level level is an integer from 0 to 10. The default value if this parameter is not specified is 0.

The higher this value, the more detail will be logged to the log files about the activities of the server. At level 0, only critical 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 log level parameter in the smb.conf file.

-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-specific 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.

-l|--log-basename=logdirectory Base directory name for log/debug files. The extension ".progname" will be appended (e.g. log.smbclient, log.smbd, etc...). The log file is never removed by the client.
