Clam On-Access Scanner(8)

NAME

clamonacc - an anti-virus on-access scanning daemon and clamd client

SYNOPSIS

clamd [options]

DESCRIPTION

The clamonacc daemon registers for file access notifications from the Linux kernel and in response, submits scans to the clamd scanning daemon for a verdict. On-Access is only available on Linux systems. On Linux, On-Access requires a kernel version >= 3.8. This is because it leverages a kernel api called fanotify to block processes from attempting to access malicious files. This prevention occurs in kernel-space, and thus offers stronger protection than a purely user-space solution.

OPTIONS

-h, --help
    Output help information and exit.

-V, --version
    Print the version number and exit.

-v, --verbose
    Be verbose.

-l FILE, --log=FILE
    Save the scan report to FILE.

-F, --foreground
    Run in foreground; do not daemonize.

-w FILE, --watch-list=FILE
    Watch directories from FILE.

-e FILE, --exclude-list=FILE
    Exclude directories from FILE.

-p A[:I], --ping A[:I]
    Ping clamd up to [A] times at optional interval [I] until it responds.

-w, --wait
    Wait up to 30 seconds for clamd to start. Optionally use alongside ping to set attempts [A] and interval [I] to check clamd.

--remove
    Remove infected files. Be careful.

--move=DIRECTORY
    Move infected files into DIRECTORY.

--copy=DIRECTORY
    Copy infected files into DIRECTORY.

-c FILE, --config-file=FILE
    Read configuration from FILE.

--allmatch
    Continue scanning within file after finding a match.

--fdpass
    Pass the file descriptor permissions to clamd. This is useful if clamd is running as a different user as it is faster than streaming the file to clamd. Only available if connected to clamd via local(unix) socket.

--stream
    Forces file streaming to clamd. This is generally not needed as clamdscan detects automatically if streaming is required. This option only exists for debugging and testing purposes, in all other cases --fdpass is preferred.

SIGNALS

ClamOnAcc recognizes the following signals:

SIGHUP
    Reopen the logfile.

SIGUSR2
    Reload the signature databases.

SIGTERM
    Perform a clean exit.
