Title: [SOLVED] How to make ssh server configuration permanent?
Post by: Adam on August 01, 2013, 06:08:30 PM

April last year, I had experience to configure ssh server (sshd) in Tiny Core Linux and had documented it here.

http://firewallengineer.wordpress.com/2012/04/01/how-to-install-and-configure-openssh-ssh-server-in-tiny-core-linux/

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?

Add it to /opt/.filetool.lst and do a backup.

Can you share example of /opt/.filetool.lst

This is what I have in my TC

root@box:~# cat /opt/.filetool.lst

Quick ssh server configuration

Quote

cd /usr/local/etc/ssh/
cp sshd_config.example sshd_config
/usr/local/etc/init.d/openssh start

Change tc password
passwd tc

To verify
ps | grep ssh
telnet tc@localhost

Thanks. This is my current config. Good things is file “usr/local/etc/ssh/sshd_config” is remain, but ssh service does not restart automatically.

Hence, I’ve to restart it manually after reboot. Is it possible to make this permanent?

You need to start it from /opt/bootlocal.sh for example. Also, you forgot to backup the passwd file.

Done. Works like a charm. Thanks a lot curaga. Now I understand how Core Linux works a little bit especially on the persistent part.
