Hallo Leute,

beim heutigen durchsehen meiner /var/log/security ist mir folgendes aufgefallen:
Code:
Jul 10 08:04:44 hpsrv sshd[883]: Connection closed by 127.0.0.1
Jul 10 08:09:44 hpsrv sshd[2196]: Connection closed by 127.0.0.1

Jul 10 08:44:44 hpsrv sshd[10894]: Connection closed by 127.0.0.1
Jul 10 08:49:44 hpsrv sshd[12076]: Connection closed by 127.0.0.1
Jul 10 08:54:44 hpsrv sshd[13237]: Connection closed by 127.0.0.1
Jul 10 08:59:44 hpsrv sshd[14380]: Connection closed by 127.0.0.1
Da wird wohl versucht, alle 5 Minuten von der lokalen Maschine eine ssh Verbindung herzustellen.
LogLevel DEBUG gibt etwas mehr Info:

Wobei auffällt, dass der Port stets wechselt.
Was kann das sein, was da läuft?

Hallo,

der Sourceport wird zufällig gewählt, von daher ist das normal.

Code:
...
client software version check_ssh_1.4.15
...
der Schippsel lässt auf Nagios oder etwas ähnliches schießen.
