April last year, I had experience to configure ssh server (sshd) in Tiny Core Linux and had documented it here.
All these were running on live cd.
When I installed TC in hard disk (VDI), I’ve noticed that /usr/local/etc/ssh/sshd_config will be gone every time I reboot my VB guest. Is there any way to make it permanent?
Table below shows a few differences of ssh setting in TC before and after ssh server configuration.
After reboot, the entire configuration made on the right side will be gone.
