Klicke in dieses Feld, um es in vollständiger Größe anzuzeigen.

Nun hab ich das Prob, daß ich deren Inhalt nicht so richtig deuten kann, da ich da nicht soooo bewandert bin.

Kann mir da mal jemand einen klitzekleinen Exkurs geben, was ich da jetzt ganz konkret rauslesen kann aus dem Protokoll?

Thx im Voraus.

> UDP Packet - Source:61.180.228.244,58304 Destination:213.54.69.15,1026

Das bedeutet, das Datenpaket (Format UDP) kommt von der Quell-IP 61.180.228.244 (dort von UDP-Port 58304), Ziel-IP ist die 213.54.69.15 (deine aktuelle IP), dort wird es auf den UDP-Port 1026 geleitet.


> PAP authentication success

Der Router hat sich erfolgreich beim Internetprovider per PAP (Password Authentication Protocol) angemeldet

Die Sachen mit LCP deuten auf einen Verbindungsaufbau per PPPoE-Protokoll hin. LCP bedeutet Link Control Protocol.

Thx, damit komme ich schon mal ein Stückchen weiter.

Eins aber noch: Was bedeutet jetzt noch der [DOS]-Eintrag am Ende der UDP-Packet-Zeilen?
Hat denn das was mit den DOS-Attacken zu tun?

Hallo, dein Router hat [DOS] angehängt, weil er dachte, das dies ein sog. Deny-of-Service Angriff wäre.
Das ist ein Angriff von sehr vielen Rechnern (->Bot-Netze), die alle sinnlose Anfragen an 1 Server stellen. Irgendwann ist das Limit erreicht, dann werden Anfragen an seinen eigentlichen Dienst (z.B. Webseite) verweigert, deshalb Deny of Service.
Bei nur ner Handvoll Anfragen kann man da nicht wirklich von sprechen, dein Router lag also falsch!
Aber den 1.Block vom 9.2 (mit der 61.180.xx) hab Ich mir mal näher angesehen und ein bisschen im Netz gestöbert:

Die Anfragen kamen aus China, und zwar genauer aus einem Internet-Cafe in Harbin (siehe Screenshot). Sie gingen alle auf Port 1026 & 1027, es war also wahrsch. ein Netzwerkscan nach offenen PCs, die direkt im Netz stehen. Diese beiden Ports werden von Windows zur Kommunikation und zur Suche nach DCOM-Diensten in Netzwerken verwendet und sind deswegen auch vom Internet erreichbar, wenn der PC direkt daran hängt! MS könnte das Problem, welches schon jahrelang besteht, einfach lösen, aber man sieht wohl keinen Anlaß dazu.:rolleyes:

Es war also sehr wohl ein Angriff, aber auf Windows-Schwachstellen! Kein DoS-Angriff, den könnte dein Router auch nicht verhindern, wenn er von außen zugemüllt wird.;) Deswegen ist diese Option in den Einstellungen dagegen auch sinnlos!

Die IP in China ist fest für die Cafes vergeben, wahrsch. hat dort ein "Begabter" mal seine 1. Gehversuche im Netz gemacht, obwohl es dort auch sehr gute "Experten" gibt, wer weiß...

Dein Router hätte diese Anfragen aber auch so geblockt, da von deiner Seite keine offene Verbindung bestanden und weil es keine entsprechenden Weiterleitungsregeln in dein lokales Netz gab.
Du kannst also die DOS-Option im Router deaktivieren, es ist dank NAT genauso sicher, aber du wirst nicht mehr von diesen Einträgen genervt!:D

Ach ja, der Screenie:
