Доброго дня. Две точки М5-400 расстояние 5.5 км. Станция стала перезагружаться периодически
Идет бесконечный лог:
7 00:06:43 dropbear[1730]: Child connection from 5.188.10.180:19778
Jan 7 00:06:47 dropbear[1730]: Login attempt for nonexistent user from 5.188.10.180:19778
Jan 7 00:06:47 dropbear[1730]: Exit before auth: Exited normally
Jan 7 00:06:47 dropbear[1731]: Child connection from 5.188.10.180:43472
Jan 7 00:06:51 dropbear[1731]: Login attempt for nonexistent user from 5.188.10.180:43472

Как от него избавиться?
Firmware Version: XW.v6.0.4
Заранее спасибо.

Попробуйте для начала обновить прошивку, и поменять номер порта SSH.

Я не очень понимаю, но по-моему идет перебор паролей... по http...
Как защитить себя от этого?

Самое простое -- поменять стандартные порты и на http/https.
Ну или поставить дропы в фаерволе на все ненадежные адреса.
