## ## Example config file for the Clam AV daemon ## Please read the clamd.conf(5) manual before editing this file. ## # Comment or remove the line below. # Example # Uncomment this option to enable logging. # LogFile must be writable for the user running daemon. # A full path is required. # Default: disabled LogFile /var/log/clamav.log # By default the log file is locked for writing - the lock protects against # running clamd multiple times (if want to run another clamd, please # copy the configuration file, change the LogFile variable, and run # the daemon with --config-file option). # This option disables log file locking. # Default: no #LogFileUnlock yes # Maximum size of the log file. # Value of 0 disables the limit. # You may use 'M' or 'm' for megabytes (1M = 1m = 1048576 bytes) # and 'K' or 'k' for kilobytes (1K = 1k = 1024 bytes). To specify the size # in bytes just don't use modifiers. # Default: 1M #LogFileMaxSize 2M # Log time with each message. # Default: no LogTime yes # Also log clean files. Useful in debugging but drastically increases the # log size. # Default: no #LogClean yes # Use system logger (can work together with LogFile). # Default: no #LogSyslog yes # Specify the type of syslog messages - please refer to 'man syslog' # for facility names. # Default: LOG_LOCAL6 #LogFacility LOG_MAIL # Enable verbose logging. # Default: no #LogVerbose yes # This option allows you to save a process identifier of the listening # daemon (main thread). # Default: disabled PidFile /var/amavis/clamd.pid # Optional path to the global temporary directory. # Default: system specific (usually /tmp or /var/tmp). #TemporaryDirectory /var/tmp # Path to the database directory. # Default: hardcoded (depends on installation options) DatabaseDirectory /var/clamav # The daemon works in a local OR a network mode. Due to security reasons we # recommend the local mode. # Path to a local socket file the daemon will listen on. # Default: disabled (must be specified by a user) LocalSocket /var/amavis/clamd # Remove stale socket after unclean shutdown. # Default: no FixStaleSocket yes # TCP port address. # Default: no #TCPSocket 3310 # TCP address. # By default we bind to INADDR_ANY, probably not wise. # Enable the following to provide some degree of protection # from the outside world. # Default: no #TCPAddr 127.0.0.1 # Maximum length the queue of pending connections may grow to. # Default: 15 #MaxConnectionQueueLength 30 # 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 options below. # Close the connection when the data size limit is exceeded. # The value should match your MTA's limit for a maximum attachment size. # Default: 10M #StreamMaxLength 20M # Limit port range. # Default: 1024 #StreamMinPort 30000 # Default: 2048 #StreamMaxPort 32000 # Maximum number of threads running at the same time. # Default: 10 #MaxThreads 20 # Waiting for data from a client socket will timeout after this time (seconds). # Value of 0 disables the timeout. # Default: 120 #ReadTimeout 300 # Waiting for a new job will timeout after this time (seconds). # Default: 30 #IdleTimeout 60 # Maximum depth directories are scanned at. # Default: 15 #MaxDirectoryRecursion 20 # Follow directory symlinks. # Default: no #FollowDirectorySymlinks yes # Follow regular file symlinks. # Default: no #FollowFileSymlinks yes # Perform a database check. # Default: 1800 (30 min) #SelfCheck 600 # Execute a command when virus is found. In the command string %v will # be replaced with the virus name. # Default: no #VirusEvent /usr/local/bin/send_sms 123456789 "VIRUS ALERT: %v" # Run as another user (clamd must be started by root to make this option # working). # Default: don't drop privileges #User clamav # Initialize supplementary group access (clamd must be started by root). # Default: no AllowSupplementaryGroups yes # Stop daemon when libclamav reports out of memory condition. #ExitOnOOM yes # Don't fork into background. # Default: no Foreground yes # Enable debug messages in libclamav. # Default: no #Debug yes # Do not remove temporary files (for debug purposes). # Default: no #LeaveTemporaryFiles yes # 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 #AlgorithmicDetection yes ## ## Executable files ## # 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, FSG, # and Petite. # Default: yes #ScanPE yes # 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 #ScanELF yes # With this option clamav will try to detect broken executables (both PE and # ELF) and mark them as Broken.Executable. # Default: no #DetectBrokenExecutables yes ## ## Documents ## # This option enables scanning of OLE2 files, such as Microsoft Office # documents and .msi files. # Default: yes #ScanOLE2 yes ## ## Mail files ## # Enable internal e-mail scanner. # Default: yes #ScanMail yes # 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 #MailFollowURLs no # Recursion level limit for the mail scanner. # Default: 64 #MailMaxRecursion 128 # With this option enabled ClamAV will try to detect phishing attempts by using # signatures. # Default: yes #PhishingSignatures yes # Scan urls found in mails for phishing attempts. # (available in experimental builds only) # Default: yes #PhishingScanURLs yes # 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! # (available in experimental builds only) # Default: yes #PhishingRestrictedScan yes # Always block SSL mismatches in URLs, even if the URL isn't in the database. # This can lead to false positives. # (available in experimental builds only) # # Default: no #PhishingAlwaysBlockSSLMismatch no # Always block cloaked URLs, even if URL isn't in database. # This can lead to false positives. # (available in experimental builds only) # # Default: no #PhishingAlwaysBlockCloak no ## ## HTML ## # Perform HTML normalisation and decryption of MS Script Encoder code. # Default: yes #ScanHTML yes ## ## Archives ## # ClamAV can scan within archives and compressed files. # Default: yes #ScanArchive yes # The options below protect your system against Denial of Service attacks # using archive bombs. # Files in archives larger than this limit won't be scanned. # Value of 0 disables the limit. # Default: 10M #ArchiveMaxFileSize 15M # Nested archives are scanned recursively, e.g. if a Zip archive contains a RAR # file, all files within it will also be scanned. This options specifies how # deeply the process should be continued. # Value of 0 disables the limit. # Default: 8 #ArchiveMaxRecursion 10 # Number of files to be scanned within an archive. # Value of 0 disables the limit. # Default: 1000 #ArchiveMaxFiles 1500 # If a file in an archive is compressed more than ArchiveMaxCompressionRatio # times it will be marked as a virus (Oversized.ArchiveType, e.g. Oversized.Zip) # Value of 0 disables the limit. # Default: 250 #ArchiveMaxCompressionRatio 300 # Use slower but memory efficient decompression algorithm. # only affects the bzip2 decompressor. # Default: no #ArchiveLimitMemoryUsage yes # Mark encrypted archives as viruses (Encrypted.Zip, Encrypted.RAR). # Default: no #ArchiveBlockEncrypted no # Mark archives as viruses (e.g. RAR.ExceededFileSize, Zip.ExceededFilesLimit) # if ArchiveMaxFiles, ArchiveMaxFileSize, or ArchiveMaxRecursion limit is # reached. # Default: no #ArchiveBlockMax no # Enable support for Sensory Networks' NodalCore hardware accelerator. # Default: no #NodalCoreAcceleration yes ## ## Clamuko settings ## WARNING: This is experimental software. It is very likely it will hang ## up your system!!! ## # Enable Clamuko. Dazuko (/dev/dazuko) must be configured and running. # Default: no #ClamukoScanOnAccess yes # Set access mask for Clamuko. # Default: no #ClamukoScanOnOpen yes #ClamukoScanOnClose yes #ClamukoScanOnExec yes # Set the include paths (all files inside them will be scanned). You can have # multiple ClamukoIncludePath directives but each directory must be added # in a seperate line. # Default: disabled #ClamukoIncludePath /home #ClamukoIncludePath /students # Set the exclude paths. All subdirectories are also excluded. # Default: disabled #ClamukoExcludePath /home/bofh # Don't scan files larger than ClamukoMaxFileSize # Value of 0 disables the limit. # Default: 5M #ClamukoMaxFileSize 10M
