Configuring the SSH server on Tiny Core Linux using OpenSSH

1. Create (and persist) a proper user

   The default tc user is passwordless, so you either want to set a password for it or perhaps create a separate user. Creating a user and setting a password is the same as on other Linux distributions. Once you do that, you'll need to persist the changes. Add these lines to the /opt/.filetool.lst:

   etc/passwd
   etc/shadow
   etc/group

2. Install the openSSH package

3. Create the SSHD configuration from the template

   cd /usr/local/etc/ssh/
   sudo cp sshd_config.orig sshd_config

4. Start the SSH daemon

   sudo /usr/local/etc/init.d/openssh start
   
   At this point you should be able to ssh into your machine.

5. Make the SSH configuration persistent

   sudo echo 'usr/local/etc/ssh' >> /opt/.filetool.lst

6. Edit the system startup file

   sudo echo '/usr/local/etc/init.d/openssh start &' >> /opt/bootlocal.sh

7. Backup your configuration files

   backup 

8. Reboot the system 

That should be it!
