I’ve keep getting the message “ssh_exchange_identification: Connection closed by remote host error” after I managed to finalized my CRUX linux on my decTOP box today. After enough looking into documentations, I finally found out that I need to edit the “/etc/hosts.allow” file to allow SSH connection, for example:
#/etc/hosts.allow
sshd:ALL
or for more conservative setting
#/etc/hosts.allow
sshd:LOCAL
sshd:192.168.1.0/255.255.255.0
I can connect ssh to my box normally after that.
