Was ich versucht habe:
Endian neu zu installieren. Ich habe eine Config vom 27.2.2023.
Dort funktionert IPS auch richtig.
Wenn ich ein Update von IPS mache, dann fällt IPS aus.
Hallo!
Seit heute morgen funktioniert IPS nicht mehr.
Das Update von IPS geht nicht und auch der Dienst IPS läuft nicht.
Dies passiert nach 5 Minuten, wenn der Firewall am Internet hängt.
Gruß
Armin
Ich kann per wget die Datenbank https://database.clamav.net/main.cvd nicht herunterladen.
wget https://database.clamav.net/main.cvd
Es erscheint der Fehler not a http or ftp url.
Wenn ich
1. main.cvd entferne und dann das Update starte, dann passiert nichts.
2. mirror.dat entferne, dann wird die mirror.dat neu geladen.
Ich habe nun main.cvd manuell geladen.
Wo kann ich diese Datei nun manuell installieren ?
welche Dateien in /var/signatures/clamav soll ich umbenenen?
bytecode.cvd
daily.cvd
eicartest.ndb
info
main.cvd
mirror.dat
Ich habe nun eine Aktualisierung von der Virendatenbank durchgeführt.

Ich habe die aktuelle Version von EFV: 3.3.5.
Es liegen keine Updates vor.
ping db.local.clamav.net funktioniert.
Dies habe ich gemacht, aber es wird immer noch auf der Hauptseite angezeigt:
clamav virus signatures 2021.02.25
Auf der Seite->Dienste->Antivirus Engine->Clamav Antivirus:
letztes Update: Feb 25 7:24:46
Das letzte Update der Virensignaturen wurde am Feb 25 07:25:16 von db.local.clamav.net mit insgesamt 8556297 Signaturen durchgeführt.
Ich habe die Datei mirrors.dat in /var/signatures/clamav gefunden.
Es ist eine Binärdatei.
Wo befindet sich die Datei mirros.dat ?

Ich habe Endian 3.3.5 installiert.
Es wird seit dem 2021.2.25 kein Update der Virendatenbank durchgeführt,
obwohl ich das Update per Hand durchführe.
Es wird auf der Hauptseite das Update nicht angezeigt, auf der Seite Dienste -> Antivirus -> wird die letzte Aktualisierungszeitpunkt angezeigt.
Ich habe eine Meldung von SNORT:
2019-01-15 10:07:21

Ist dies ein Problem ?
Bei mir liegt eine ganze Menge Schnee.
Ich wohne bei Augsburg.
Schöne Weihnachten und einen guten Rutsch in das neue Jahr !
Ja, ich benutze Kubuntu und der Eintrag stammt von "apt-get update" auf der Konsole.
Kann ich als gelöst markieren.
Ich habe folgende Einträge im Protokoll von IPS gefunden:

Wie zu erkennen ist, benutze ich Kubuntu.
Sind diese Einträge Grund zur Sorge ?
