AntiVirus Scanner 3.7.1 (OpenSSL Debian branch)
11-15-2008
AVScan is an anti-virus scanner that uses the ClamAV library (libclamav). It allows you to create a list of scan items for frequently scanned locations and features on-demand virus database updating, manual drag and drop object scanning, and pausing and resuming of scanning, all in a simple GUI environment.

vscand(1M) System Administration Commands vscand(1M) NAME
vscand - vscan service daemon SYNOPSIS
/usr/lib/vscan/vscand DESCRIPTION
vscand is the daemon that handles virus scan requests from file systems on file open and close operations. A file system may support enabling and disabling of virus scanning on a per dataset basis, using that file system's administrative command, for example zfs(1M). If the file state or scan policy (see vscanadm(1M) requires that a file be scanned, vscand communicates with external third-party virus scanners (scan engines) using the Internet Content Adaptation Protocol (ICAP, RFC 3507) to have the file scanned. A file is submitted to a scan engine if it has been modified since it was last scanned, or if it has not been scanned with the latest scan engine configuration (Virus definitions). The file's modified attribute and scanstamp attribute are used to store this information. Once the file is scanned, the modified attribute is cleared and the scanstamp attribute is updated. If the file is found to contain a virus, the virus is logged in syslogd(1M), an audit record is written, and the file is quarantined (by setting its quarantine attribute). Once a file is quarantined, attempts to read, execute or rename the file will be denied by the file sys- tem. The syslogd(1M) entry and the audit record specify the name of the infected file and the violations detected in the file. Each viola- tion is specified as "ID - threat description", where ID and threat description are defined in the X-Infection-Found-Header in ICAP RFC 3507; Extensions. By default, vscand connects to scan engines on port 1344. The port and other service configuration parameters can be configured using vscanadm(1M). The vscan service is disabled by default, and can be enabled using svcadm(1M). EXIT STATUS
The following exit values are returned: 0 Daemon started successfully. non-zero Daemon failed to start. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWvscanu | +-----------------------------+-----------------------------+ |Interface Stability |Uncommitted | +-----------------------------+-----------------------------+ SEE ALSO

If a file is accessed using a protocol which does not invoke the file system open and close operations, for example NFSv3, virus scanning is not initiated on the file. File content is transferred to the scan engines as cleartext data. Administrative actions for the vscan service, such as enabling, disabling, or requesting a restart, can be performed using svcadm(1M). The vscan service status can be queried using the svcs(1) command. The vscan service is managed by the service management facility, smf(5), under the service identifier: svc:/system/filesystem/vscan SunOS 5.11 6 Nov 2007 vscand(1M)
