13 Creating a scanner client
14 use ClamAV::Client;
15 # Try using socket options from clamd.conf, or use default socket:
17 my $scanner = ClamAV::Client->new();
18 # Use a local Unix domain socket:
20 my $scanner = ClamAV::Client->new(
21 socket_name => '/var/run/clamav/clamd.ctl'
22 );
23 # Use a TCP socket:
25 my $scanner = ClamAV::Client->new(
26 socket_host => '127.0.0.1',
27 socket_port => 3310
28 );
29 die("ClamAV daemon not alive")
31 if not defined($scanner) or not $scanner->ping();
32 Daemon maintenance
34 my $version = $scanner->version;
35 # Retrieve the ClamAV version string.
36 $scanner->reload(); # Reload the malware pattern database.
38 $scanner->quit(); # Terminates the ClamAV daemon.
40 $scanner->shutdown(); # Likewise.
41 Path scanning (lazy)
43 # Scan a single file or a whole directory structure,
44 # and stop at the first infected file:
45 my ($path, $result) = $scanner->scan_path($path);
46 my ($path, $result) = $scanner->scan_path(
47 $path, ClamAV::Client::SCAN_MODE_NORMAL );
48 my ($path, $result) = $scanner->scan_path(
49 $path, ClamAV::Client::SCAN_MODE_RAW );
50 Path scanning (complete)
52 # Scan a single file or a whole directory structure,
53 # and scan all files without stopping at the first infected one:
54 my %results = $scanner->scan_path_complete($path);
55 while (my ($path, $result) = each %results) { ... }
56 Other scanning methods
58 # Scan a stream, i.e. read from an I/O handle:
59 my $result = $scanner->scan_stream($handle);
60 # Scan a scalar value:
62 my $result = $scanner->scan_scalar(\$value);

65 ClamAV::Client is a class acting as a client for a ClamAV "clamd" virus
66 scanner daemon. The daemon may run locally or on a remote system as
67 ClamAV::Client can use both Unix domain sockets and TCP/IP sockets.
68 The full functionality of the "clamd" client/server protocol is
69 supported.
70 Constructor
72 The following constructor is provided:
73 new(%options): RETURNS ClamAV::Client
75 Creates a new "ClamAV::Client" object. If no socket options are
76 specified, first the socket options from the local "clamd.conf"
77 configuration file are tried, then the Unix domain socket
78 "/var/run/clamav/clamd.ctl" is tried, then finally the TCP/IP
79 socket at 127.0.0.1 on port 3310 is tried. If either Unix domain
80 or TCP/IP socket options are explicitly specified, only these are
81 used.
82 %options is a list of key/value pairs representing any of the
84 following options:
85 socket_name
87 A scalar containing the absolute name of the local Unix domain
88 socket. Defaults to '/var/run/clamav/clamd.ctl'.
89 socket_host
91 A scalar containing the name or IP address of the TCP/IP
92 socket. Defaults to '127.0.0.1'.
93 socket_port
95 A scalar containing the port number of the TCP/IP socket.
96 Defaults to 3310.
97 Instance methods
99 The following instance methods are provided:
100 Daemon maintenance
102 ping: RETURNS SCALAR; THROWS ClamAV::Client::Error
104 Returns true ('PONG') if the ClamAV daemon is alive. Throws a
105 ClamAV::Client::Error exception otherwise.
106 version: RETURNS SCALAR; THROWS ClamAV::Client::Error
108 Returns the version string of the ClamAV daemon.
109 reload: RETURNS SCALAR; THROWS ClamAV::Client::Error
111 Instructs the ClamAV daemon to reload its malware database.
112 Returns true if the reloading succeeds, or throws a
113 ClamAV::Client::Error exception otherwise.
114 quit: RETURNS SCALAR; THROWS ClamAV::Client::Error
116 shutdown: RETURNS SCALAR; THROWS ClamAV::Client::Error
117 Terminates the ClamAV daemon. Returns true if the termination
118 succeeds, or throws a ClamAV::Client::Error exception otherwise.
119 scan_path($path): RETURNS SCALAR, SCALAR; THROWS ClamAV::Client::Error
121 scan_path($path, $scan_mode): RETURNS SCALAR, SCALAR; THROWS
122 ClamAV::Client::Error
123 Scans a single file or a whole directory structure, and stops at
124 the first infected file found. The specified path must be
125 absolute. A scan mode may be specified: a mode of
126 ClamAV::Client::SCAN_MODE_NORMAL (which is the default) causes a
127 normal scan ("SCAN") with archive support enabled, a mode of
128 ClamAV::Client::SCAN_MODE_RAW causes a raw scan with archive
129 support disabled.
130 If an infected file is found, returns a list consisting of the path
132 of the file and the name of the malware signature that matched the
133 file. Otherwise, returns the originally specified path and undef.
134 scan_path_complete($path): RETURNS HASH; THROWS ClamAV::Client::Error
136 Scans a single file or a whole directory structure completely, not
137 stopping at the first infected file found. The specified path must
138 be absolute. Only the normal, non-raw mode is supported for
139 complete scans by ClamAV.
140 Returns a hash with a list of infected files found, with the file
142 paths as the keys and the matched malware signature names as the
143 values.
144 scan_stream($handle): RETURNS SCALAR; THROWS ClamAV::Client::Error
146 Scans a stream, that is, reads from an I/O handle. If the stream
147 is found to be infected, returns the name of the matching malware
148 signature, undef otherwise.
149 scan_scalar(\$value): RETURNS SCALAR; THROWS ClamAV::Client::Error
151 Scans the value referenced by the given scalarref. If the value is
152 found to be infected, returns the name of the matching malware
153 signature, undef otherwise.
