.SH DESCRIPTION
.sp
.LP
The \fBvscanadm\fR command sets and displays properties of the \fBvscan\fR
service, \fBvscand\fR(1M), and provides scan statistics.
.sp
.LP
File system exemption from virus scanning may be configured per file system
using the appropriate file system administrative command, for example
\fBzfs\fR(1M).
.sp
.LP
Scan engines are third-party applications on external hosts that perform the
actual virus scanning operation on files. Multiple scan engines can be
configured for use by the \fBvscan\fR service. A minimum of two scan engines is
recommended. File scan requests are distributed among the configured scan
engines to achieve load balancing. A scan engine is identified by its
\fIengine_id\fR. The \fIengine_id\fR is a user defined string of up to 64
bytes.
.sp
.LP
The \fBvscan\fR service properties are divided into two categories: scan engine
properties, which are specific to a scan engine definition, and general
properties, which apply to the service and are not scan engine-specific.

The following properties are available for the \fBvscanadm set\fR and
\fBvscanadm get\fR subcommands:
.sp
.ne 2
.mk
.na
\fB\fBmax-size\fR\fR
.ad
.RS 19n
.rt  
The maximum size of files that should be virus scanned. Files exceeding
\fImax-size\fR are not scanned. The \fImax-size-action\fR property determines
whether access should be allowed or denied to files that exceed \fImax-size\fR.
.sp
The value of \fImax-size\fR is a string with a numeric (decimal) component and
an optional letter component that specifies a unit size, in the format
"N[.N][KMGTP][B]".
.sp
Following the numeric component, the optional unit can be specified as either
one or two characters. For example, either "K" or "KB" can be used to specify
kilobytes. Unit specifiers are not case-sensitive, and must follow the numeric
value immediately with no intervening whitespace.
.sp
With either no unit specifier, or a unit specifier of only "B", the numeric
value is assumed to be in bytes. The default value is 1GB.
.sp
Note that while the \fBvscan\fR service defines a maximum file size for
scanning, scan engines also typically define their own maximum file size
setting. It is recommended that \fImax-size\fR be set to a value less than or
equal to the maximum file size for the scan engine(s).
.RE

.sp
.ne 2
.mk

\fB\fBmax-size-action\fR\fR

.sp
.ne 2

\fBallow\fR
.ad
.RS 9n
.rt  
allow access to files larger than \fImax-size\fR (no virus scan). This is the

The following properties are available for the \fBvscanadm import\fR,
\fBvscanadm export\fR, and \fBvscanadm validate\fR subcommands:
.sp
.ne 2
.mk
.na
\fB\fBtypes\fR\fR
.ad
.RS 9n
.rt  
A comma-separated list of file type extension matching rules. This list defines
which types of files are scanned and which should be excluded during virus
scanning. Each rule comprises the rule indicator [+|-], followed by a file type
\fIexpresssion\fR against which a file's type extension is compared. The file
type \fIexpresssion\fR is case insensitive and may include the "*" and "?"
wildcards. There should be no whitespace between the rule indicator and the
file type \fIexpresssion\fR. If a comma is included within the file type
expression, it must be escaped using a "\e" (backslash). A file type extension
does not include its preceding dot.
.sp
The rule indicator is a single character and can be one of:
.sp
.in +2
.nf
+ include file type in virus scanning
- exclude file type from virus scanning
.fi
.in -2
.sp

When a file is being evaluated as a candidate for virus scanning, its file type
will be compared with the rules defined in types. The first rule matched will
be applied. If no match is found, the file will be virus scanned. The total
length of the types string can not exceed 4096 bytes. The default content of
the types list is "+*".
