Ho appena installato il mio Raspberry Pi. Controllando il file Auth.log, ho notato alcuni tentativi falliti da un indirizzo IP esterno. Tuttavia, c'è stato un (ultimo) tentativo che mi ha confuso.
Questa linea (nota anche che l'ora è andata indietro)
Feb 23 21:29:52 raspberrypi sshd[17102]: Connection from 210.107.198.201 port 43566 on 192.168.0.102 port 22
Feb 23 21:17:13 raspberrypi systemd-logind[341]: New seat seat0.
Non sono un esperto di sicurezza, ma so che systemd-logind è un demone che gestisce gli accessi, ma il New seat seat0 'indica qualcosa di successo?
I documenti non l'hanno davvero chiarito per me. Penso che sia correlato a questo
AttachDevice() may be used to assign a specific device to a specific seat. The device is identified by its /sys path, and must be eligible for seat assignments. Takes three arguments: the seat id, the sysfs path, and a boolean for controlling PolicyKit interactivity (see above). Device assignments are persistently stored to disk. To create a new seat, simply specify a previously unused seat id. For more information about the seat assignment logic see Multi-Seat for Linux.
