Environment

McAfee VirusScan Enterprise for Linux  (VSEL) 2.0.x, 1.9.x

Summary

VSEL command line commands and options:
 
 Command  Description
/etc/init.d/nails
Starts VSEL processes, which include:
  • nailsd - Scan Manager and Scheduler
  • scanner - anti-virus software: scanner and cleaner
  • mon - interface communications
  • nailswebd - web server
  • nailslogd - configuration, log/alerting
  • ods - On-Demand Scanner
  • nails-update - Updater
NOTE: The lshook and linuxshield kernel modules are also loaded if OAS is enabled.
/etc/init.d/nails stop Stops all VSEL services.
/etc/init.d/nails restart Performs a stop, and then a start.
/etc/init.d/nails reload Reloads the configuration information. This is required only if manual changes are made to configuration files rather than by using the browser interface.
/etc/init.d/nails status Provides status on the running services.
<INSTALL_DIR>/bin/nails --help Displays brief information about all nails commands.
<INSTALL_DIR>/bin/nails --version Displays information about the product version.
<INSTALL_DIR>/bin/nails dump [--verbose] Diagnostic report. This is the same report that is produced by clicking Diagnostic Report on the Scanning Summary page of the browser interface.
The --verbose flag provides more detail, but this greatly increases the size of the report and the time to generate the report.
The output of the command should be redirected to a file.
<INSTALL_DIR>/bin/nails on-access –disable Disables on-access scanning.
<INSTALL_DIR>/bin/nails on-access --enable Enables on-access scanning.
<INSTALL_DIR>/bin/nails on-access --flush Clears the cache of scanned files, forcing the on-access scanner to re-scan files when they are next accessed.
<INSTALL_DIR>/bin/nails on-access –queue Displays information about files currently being processed by the on-access scanner.
<INSTALL_DIR>/bin/nails on-access --status Displays the status of the on-access scanner, whether enabled or disabled.
<INSTALL_DIR>/bin/nails passwd Changes the password for the nails user.
<INSTALL_DIR>/bin/nails quarantine --list [--verbose] Displays information about the files in the on-access quarantine directory.
The metafiles in the quarantine directory provide information that can be used to restore the file.
<INSTALL_DIR>/bin/nails quarantine --recover <meta-file> [<destination-file>] Uses information in the .metafile to recover a file and move the file to its original location, or to the <destination-file>.
Use this command only when a non-infected file has been incorrectly quarantined.
The recovered file might be quarantined again when accessed unless an exclusion has been set up for the recovered file.
<INSTALL_DIR>/bin/nails task --list Lists tasks created at the browser-based interface.
<INSTALL_DIR>/bin/nails task --run taskid Runs the specified task immediately.
<INSTALL_DIR>/bin/nails task --stop taskid Stops the specified task.
/opt/NAI/LinuxShield/bin/khm_setup –c Compiles kernel modules manually using RKMS.
/opt/NAI/LinuxShield/bin/khm_setup –t Tests kernel modules compiled using RKMS. Logs are stored under /opt/NAI/LinuxShield/src/logs.
/opt/NAI/LinuxShield/bin/khm_setup –e <archive path with name> Exports kernel modules to the given path.
/opt/NAI/LinuxShield/bin/khm_setup –i <kernel module archive path> Imports kernel modules from the given path.
cat /opt/NAI/LinuxShield/etc/HF-Version Determine which hotfixes are installed (if any)
