NAME
clamd.conf - Configuration file for Clam AntiVirus Daemon
DESCRIPTION
clamd.conf configures the Clam AntiVirus daemon, clamd(8).
FILE FORMAT
The file consists of comments and options with arguments. Each line which starts with a hash (#) symbol is ignored by the parser. Options and arguments are case sensitive and of the form Option Argument. The arguments are of the following types:- BOOL
- Boolean value (yes/no or true/false or 1/0).
- STRING
- String without blank characters.
- SIZE
- Size in bytes. You can use 'M' or 'm' modifiers for megabytes and 'K' or 'k' for kilobytes.
- NUMBER
- Unsigned integer.
DIRECTIVES
When some option is not used (commented out or not included in the configuration file at all) clamd takes a default action.
- Example
- If this option is set clamd will not run.
- LogFile STRING
- Enable logging to selected file.
Default: no - LogFileUnlock BOOL
- Disable a system lock that protects against running clamd with the same configuration file multiple times.
Default: no - LogFileMaxSize SIZE
- Limit the size of the log file. The logger will be automatically disabled if the file is greater than SIZE. Value of 0 disables the limit.
Default: 1M - LogTime BOOL
- Log time for each message.
Default: no - LogClean BOOL
- Log clean files.
Default: no - LogSyslog BOOL
- Use system logger (can work together with LogFile).
Default: no - LogFacility STRING
- Specify the type of syslog messages - please refer to 'man syslog' for facility names.
Default: LOG_LOCAL6 - LogVerbose BOOL
- Enable verbose logging.
Default: no - PidFile STRING
- Save the process identifier of a listening daemon (main thread) to a specified file.
Default: no - TemporaryDirectory STRING
- Optional path to the global temporary directory.
Default: system specific (usually /tmp or /var/tmp). - DatabaseDirectory STRING
- Path to a directory containing database files.
Default: /var/lib/clamav - LocalSocket STRING
- Path to a local (Unix) socket the daemon will listen on.
Default: no - FixStaleSocket BOOL
- Remove stale socket after unclean shutdown.
Default: no - TCPSocket NUMBER
- TCP port number the daemon will listen on.
Default: no - TCPAddr STRING
- TCP socket address to bind to. By default clamd binds to INADDR_ANY.
Default: no - MaxConnectionQueueLength NUMBER
- Maximum length the queue of pending connections may grow to.
Default: 15 - MaxThreads NUMBER
- Maximum number of threads running at the same time.
Default: 10 - ReadTimeout NUMBER
- Waiting for data from a client socket will timeout after this time (seconds).
Default: 120 - IdleTimeout NUMBER
- Waiting for a new job will timeout after this time (seconds).
Default: 30 - MaxDirectoryRecursion NUMBER
- Maximum depth directories are scanned at.
Default: 15 - FollowDirectorySymlinks BOOL
- Follow directory symlinks.
Default: no - FollowFileSymlinks BOOL
- Follow regular file symlinks.
Default: no - SelfCheck NUMBER
- Perform a database check.
Default: 1800 - VirusEvent COMMAND
- Execute COMMAND when a virus is found. In the command string %v will be replaced with the virus name.
Default: no - ExitOnOOM BOOL
- Stop daemon when libclamav reports out of memory condition.
Default: no - User STRING
- Run as another user (clamd must be started by root to make this option working).
Default: no - AllowSupplementaryGroups BOOL
- Initialize supplementary group access (clamd must be started by root).
Default: no - Foreground BOOL
- Don't fork into background.
Default: no - Debug BOOL
- Enable debug messages from libclamav.
- LeaveTemporaryFiles BOOL
- Do not remove temporary files (for debug purpose).
Default: no - StreamMaxLength SIZE
- Clamd uses FTP-like protocol to receive data from remote clients. If you are using clamav-milter to balance load between remote clamd daemons on firewall servers you may need to tune the Stream* options. This option allows you to specify the upper limit for data size that will be transfered to remote daemon when scanning a single file. It should match your MTA's limit for a maximum attachment size.
Default: 10M - StreamMinPort NUMBER
- Limit data port range.
Default: 1024 - StreamMaxPort NUMBER
- Limit data port range.
Default: 2048 - DetectPUA
- Detect Possibly Unwanted Applications.
Default: No - AlgorithmicDetection BOOL
- In some cases (eg. complex malware, exploits in graphic files, and others), ClamAV uses special algorithms to provide accurate detection. This option controls the algorithmic detection.
Default: yes - ScanPE BOOL
- PE stands for Portable Executable - it's an executable file format used in all 32 and 64-bit versions of Windows operating systems. This option allows ClamAV to perform a deeper analysis of executable files and it's also required for decompression of popular executable packers such as UPX.
Default: yes - ScanELF BOOL
- Executable and Linking Format is a standard format for UN*X executables. This option allows you to control the scanning of ELF files.
Default: yes - DetectBrokenExecutables BOOL
- With this option clamd will try to detect broken executables (both PE and ELF) and mark them as Broken.Executable.
Default: no - ScanOLE2 BOOL
- This option enables scanning of OLE2 files, such as Microsoft Office documents and .msi files.
Default: yes - ScanPDF BOOL
- This option enables scanning within PDF files.
Default: no - ScanHTML BOOL
- Enables HTML detection and normalisation.
Default: yes - ScanMail BOOL
- Enable scanning of mail files.
Default: yes - MailFollowURLs BOOL
- If an email contains URLs ClamAV can download and scan them. WARNING: This option may open your system to a DoS attack. Never use it on loaded servers.
Default: no - MailMaxRecursion NUMBER
- Recursion level limit for the mail scanner.
Default: 64 - PhishingSignatures BOOL
- With this option enabled ClamAV will try to detect phishing attempts by using signatures.
Default: yes - PhishingScanURLs BOOL
- Scan URLs found in mails for phishing attempts using heuristics. This will classify "Possibly Unwanted" phishing emails as Phishing.Heuristics.Email.*
Default: yes - PhishingRestrictedScan BOOL
- Use phishing detection only for domains listed in the .pdb database. It is not recommended to have this option turned off, because scanning of all domains may lead to many false positives!
Default: yes - PhishingAlwaysBlockSSLMismatch BOOL
- Always block SSL mismatches in URLs, even if the URL isn't in the database. This can lead to false positives.
Default: no - PhishingAlwaysBlockCloak BOOL
- Always block cloaked URLs, even if URL isn't in database. This can lead to false positives.
Default: no - ScanArchive BOOL
- Enable archive scanning.
Default: yes - ArchiveMaxFileSize SIZE
- Files in archives larger than this limit won't be scanned. Value of 0 disables the limit.
Default: 10M - ArchiveMaxRecursion NUMBER
- Limit archive recursion level. Value of 0 disables the limit.
Default: 8 - ArchiveMaxFiles NUMBER
- Number of files to be scanned within an archive. Value of 0 disables the limit.
Default: 1000 - ArchiveMaxCompressionRatio NUMBER
- Analyze compression ratio of every file in an archive and mark potential archive bombs as viruses (0 disables the limit).
Default: 250 - ArchiveLimitMemoryUsage BOOL
- Use slower decompression algorithm which uses less memory. This option only affects the bzip2 decompressor.
Default: no - ArchiveBlockEncrypted BOOL
- Mark encrypted archives as viruses (Encrypted.Zip, Encrypted.RAR).
Default: no - ArchiveBlockMax BOOL
- Mark archives as viruses (e.g RAR.ExceededFileSize, Zip.ExceededFilesLimit) if ArchiveMaxFiles, ArchiveMaxFileSize, or ArchiveMaxRecursion limit is reached.
Default: no - NodalCoreAcceleration BOOL
- Enable support for Sensory Networks' NodalCore hardware accelerator.
Default: no - ClamukoScanOnAccess BOOL
