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.

#/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.

To erase the entire disk, run:
wodim dev=/dev/cdrom blank=fast
That’s all!
