Wenn ich tail -f /var/log/syslog verwende, sieht man, dass diese Zugriffe dauerhaft erfolgen (ohne Pause).

Diese Zugriffe sind so häufig, dass in /var/log/messages ständig steht, dass sie gedroppt wurden.

Code: 
Feb  3 09:47:30 rsyslogd-2177: imuxsock begins to drop messages from pid 23287 due to rate-limiting
Feb  3 09:47:35 rsyslogd-2177: imuxsock lost 88 messages from pid 23287 due to rate-limiting

Wurde mein Server gehackt und wird als Spamschleuder mißbraucht oder ist das ein Scriptkiddy welches Sicherheitslücken sucht?

Wer kann dazu was sagen?

Danke und Gruß
Matthias
 
Ja - das Loglevel ist auf verbose gestellt.

Code: 
smtp      inet  n       -       -       -       -       smtpd -v

Leider beantwortet das meine Frage aber nicht warum jemand dauerhaft mein Postfix connected bzw. was diese pausenlosen Zugriffe der selben IP zu bedeuten haben.

Dafür muss es doch einen Grund geben!
 
Hi und Guten Abend,

Die Frage solte doch sehr einfach geklert sein ;)

Ich gehe mal von Automatisierten Anfragen mittels Bots aus die Versuchen bei dir Mails abzusetzen... solange dein MTA kein OpenRelay ist und mind. SASL als Auth.methode für das Senden nutzt kanst du es ignoieren oder via fai2lban / eigenem filterscript deiner firewall überlassen.

WIe Schaut es den mit nem Blacklist Check deines Servers aus?

Script-kiddys und Nervige BOT's solten ansonsten wenn dein System sauber ist und Hinreichend Abgesichert wurde als Hintergrundrauschen Betrachtet werden :D:D:D
