Kann mir dass jemand genau erklären? Mich interessieren die IGMP requests von 172.18.94.167 (Aon dfü server) an 224.0.0.1 .
Was soll dass sein? Versucht Aon über diese multicast requests herauszufinden ob bei mir mehr als ein rechner am netz hängt?

soweit ich mich erinnern kann wird mit dem internet group management protocol einem multicast router mitgeteilt, ob sich eine oder mehrere groups in einem subnet befinden oder nicht. mit einem gruppenspezifischen query kann auch in die gruppe "hineingefragt" werden, wer alles darin versammelt ist, was auf Deine frage hinzielt. inwieweit das auch funktioniert wenn du ip masq betreibst weiss ich nicht. igmp ist sicherlich in einem rfc genau beschrieben. wenn es ganz wichtig ist kann ich mal mein archiv durchsuchen und es dir mailen.

würde mich auch interessieren!

@nermal: Was ich nicht ganz verstehe ist warum der dfü server dass macht, was ist der sinn? Ich weis zwar nicht wieviele dialup clients dieser dfü server managt aber ich stell mir vor dass der dfü server auf der einen seite mit einem router, und auf der anderen mit mehreren adsl ants verbunden ist. Also wozu sind diese multicast requests gut? Die clients sind ja bekannt, und der router übernimmt den rest. Dass der server mit dieser methode nach illegalen arbeitsplätzen sucht kann ich mir nach weiterer überlegung nicht vorstellen da er diese ja nur sehen würde wenn sie gültige ip adressen hätten, was nicht der fall sein kann da der server ja nur eine vergibt. Wozu IGMP und der 124'er adressbereich gut sind ist mir schon klar ich würde nur gern die sinnhaftigkeit dieser aktionen in diesem fall verstehen lernen.

Brauchst nicht nach den rfc suchen hab's gefunden aber viel geholfen hats nicht, is sowieso nicht wichtig, würd mich nur interessieren.

Vielen dank,

sinn des ganzen ist afaik in einem stark ausgelasteten netz nachzusehen, welche (dyn.) ips / subnets belegt bzw. wieder neu vergeben werden koennen. ich weiss, es gibt eine moeglichkeit, hinter Deinen router daheim zu schauen, aber obs mit igmp geht ... *schulterzuck*
vielleicht sollt ich das rfc auch mal lesen

Also ich glaub ich weis jetzt worums geht, die adresse 124.0.0.1 adressiert alle multicast hosts am lokalen netzwerk und ist eigentlich für den router des dfü servers gedacht, meine firewall logt das halt weil ich ja auch am selben netzwerk häng und damit die multicasts empfange.

@nermal: auf meinem router läuft eine firewall die sämtliche incoming traffic blockt, ausser über einen trojaner kann ich mir nicht vorstellen wie man da dahinter äugen könnte (ohne firewall is was anderes) ?
