ClamAV::Client(3pm) User Contributed Perl Documentation ClamAV::Client(3pm) NAME
ClamAV::Client - A client class for the ClamAV "clamd" virus scanner daemon VERSION
0.11 SYNOPSIS
Creating a scanner client use ClamAV::Client; # Try using socket options from clamd.conf, or use default socket: my $scanner = ClamAV::Client->new(); # Use a local Unix domain socket: my $scanner = ClamAV::Client->new( socket_name => '/var/run/clamav/clamd.ctl' ); # Use a TCP socket: my $scanner = ClamAV::Client->new( socket_host => '127.0.0.1', socket_port => 3310 ); die("ClamAV daemon not alive") if not defined($scanner) or not $scanner->ping(); Daemon maintenance my $version = $scanner->version; # Retrieve the ClamAV version string. $scanner->reload(); # Reload the malware pattern database. $scanner->quit(); # Terminates the ClamAV daemon. $scanner->shutdown(); # Likewise. Path scanning (lazy) # Scan a single file or a whole directory structure, # and stop at the first infected file: my ($path, $result) = $scanner->scan_path($path); my ($path, $result) = $scanner->scan_path( $path, ClamAV::Client::SCAN_MODE_NORMAL ); my ($path, $result) = $scanner->scan_path( $path, ClamAV::Client::SCAN_MODE_RAW ); Path scanning (complete) # Scan a single file or a whole directory structure, # and scan all files without stopping at the first infected one: my %results = $scanner->scan_path_complete($path); while (my ($path, $result) = each %results) { ... } Other scanning methods # Scan a stream, i.e. read from an I/O handle: my $result = $scanner->scan_stream($handle); # Scan a scalar value: my $result = $scanner->scan_scalar($value); DESCRIPTION
ClamAV::Client is a class acting as a client for a ClamAV "clamd" virus scanner daemon. The daemon may run locally or on a remote system as ClamAV::Client can use both Unix domain sockets and TCP/IP sockets. The full functionality of the "clamd" client/server protocol is supported. Constructor The following constructor is provided: new(%options): RETURNS ClamAV::Client Creates a new "ClamAV::Client" object. If no socket options are specified, first the socket options from the local "clamd.conf" configuration file are tried, then the Unix domain socket "/var/run/clamav/clamd.ctl" is tried, then finally the TCP/IP socket at 127.0.0.1 on port 3310 is tried. If either Unix domain or TCP/IP socket options are explicitly specified, only these are used. %options is a list of key/value pairs representing any of the following options: socket_name A scalar containing the absolute name of the local Unix domain socket. Defaults to '/var/run/clamav/clamd.ctl'. socket_host A scalar containing the name or IP address of the TCP/IP socket. Defaults to '127.0.0.1'. socket_port A scalar containing the port number of the TCP/IP socket. Defaults to 3310. Instance methods The following instance methods are provided: Daemon maintenance ping: RETURNS SCALAR; THROWS ClamAV::Client::Error Returns true ('PONG') if the ClamAV daemon is alive. Throws a ClamAV::Client::Error exception otherwise. version: RETURNS SCALAR; THROWS ClamAV::Client::Error Returns the version string of the ClamAV daemon. reload: RETURNS SCALAR; THROWS ClamAV::Client::Error Instructs the ClamAV daemon to reload its malware database. Returns true if the reloading succeeds, or throws a ClamAV::Client::Error exception otherwise. quit: RETURNS SCALAR; THROWS ClamAV::Client::Error shutdown: RETURNS SCALAR; THROWS ClamAV::Client::Error Terminates the ClamAV daemon. Returns true if the termination succeeds, or throws a ClamAV::Client::Error exception otherwise. scan_path($path): RETURNS SCALAR, SCALAR; THROWS ClamAV::Client::Error scan_path($path, $scan_mode): RETURNS SCALAR, SCALAR; THROWS ClamAV::Client::Error Scans a single file or a whole directory structure, and stops at the first infected file found. The specified path must be absolute. A scan mode may be specified: a mode of ClamAV::Client::SCAN_MODE_NORMAL (which is the default) causes a normal scan ("SCAN") with archive support enabled, a mode of ClamAV::Client::SCAN_MODE_RAW causes a raw scan with archive support disabled. If an infected file is found, returns a list consisting of the path of the file and the name of the malware signature that matched the file. Otherwise, returns the originally specified path and undef. scan_path_complete($path): RETURNS HASH; THROWS ClamAV::Client::Error Scans a single file or a whole directory structure completely, not stopping at the first infected file found. The specified path must be absolute. Only the normal, non-raw mode is supported for complete scans by ClamAV. Returns a hash with a list of infected files found, with the file paths as the keys and the matched malware signature names as the values. scan_stream($handle): RETURNS SCALAR; THROWS ClamAV::Client::Error Scans a stream, that is, reads from an I/O handle. If the stream is found to be infected, returns the name of the matching malware signature, undef otherwise. scan_scalar($value): RETURNS SCALAR; THROWS ClamAV::Client::Error Scans the value referenced by the given scalarref. If the value is found to be infected, returns the name of the matching malware signature, undef otherwise. SEE ALSO
