Hi ! Unexpectedly I've got this warning on one of the servers: SSH warning: Permissions 0640 for '/etc/ssh/ssh_host_xxx_key' are too open Because of this, ssh daemon have not written any logs. I have fail2ban installed from the beginning and checking log showed that it continuously banned many IPs. Have no idea when this happens. Quite strange since I never changed permissions of these files, only installed syslog-ng instead of default logger, and limited log file size to 100MB. Does it mean server was somehow compromised ? PS. Usually SSH root login shows message "last successful login from ***" or "last failed login from ***". Now there are no such message.
