 Posted: Sat Nov 05, 2005 11:13 am Post subject: clamav Konfiguration |
 |
|
Hallo
Ich möchte, daß mein home-Verzeichnis permanent überwacht wird und clamav (freshclam) beim Systemstart nach updates(virendefinition) sucht. Gefundene Viren sollen per email an root gepostet werden.
Ich habe dazuko im Kernel und das Modul wird auch geladen. clamav und fresclam werden im default runlevel ohne Fehlermeldungen gestartet.
Ich glaube, meine Konfigurationsdateien sind nicht ganz rund. Vielleicht kann mir jemand helfen?
| Code: |
cat clamd.conf | grep \# -v | sort
ClamukoIncludePath /home/olaf
ClamukoScanArchive
ClamukoScanOnAccess
FixStaleSocket
LocalSocket /var/run/clamav/clamd.sock
LogFile /var/log/clamav/clamd.log
LogTime
PidFile /var/run/clamav/clamd.pid
ScanArchive
ScanRAR

# A full path is required.
# Default: disabled
LogFile /var/log/clamav/clamd.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: disabled
#LogFileUnlock
# Maximal size of the log file.
# Value of 0 disables the limit.
# You may use 'M' or 'm' for megabytes (1M = 1m = 1048576 bytes)

# in bytes just don't use modifiers.

# Default: disabled
LocalSocket /var/run/clamav/clamd.sock
# Remove stale socket after unclean shutdown.
# Default: disabled

Wärest du so gut und würdest du bitte Kommentare aus den Listings entfernen? Da selbige auch bei denjenigen vorhanden sind, die dir helfen, sind sie hier redundant.

haha, da knüpf ich gleich an das thema an: ich suche einen freien virenscanner für linux. ist clamav empfehlenswert? wie aktuell sind da die virendefinitionen? (das projekt openantivirus.com scheint ja tot zu sein ... die virensignaturen sind nicht gerade aktuell...)

Ich denke schon. Die Virendefinitionen werden täglich aktualisiert. Auf der clamav-Homepage stehen noch mehr Details, und es sind auch Organisationen aufgeführt, die es einsetzen. Darunter sind unter anderem SourceForge, Fastmail, DynDNS, diverse Universitäten und viele mehr. Ach ja, und ich benutze es auch. 
Also kann es ja nicht allzu schlecht sein.
