SSL certificate by Let’s Encrypt and Zyxel NSA325 v2?

Jappo

Hello community,

I want to integrate a SSL certificate by Let’s Encrypt into my Zyxel NSA325 v2 to encrypt the data between the NAS and the web GUI which is accessible at https://some.dns.tld.

I got a folder called .well-known which I have to upload to the document root of the webserver running on the NAS to verify that I am the person that applied for the certificate. The folder has to be accessible at https://some.dns.tld/.well-known.

The NSA325 webserver’s document root is /usr/local/apache/htdocs if I am correct.

I can upload files via SCP with admin to /home/shares or with root to /root. Then I want to move them via SSH to /usr/local/apache/htdocs. But that throws an error:

mv: can't create '/usr/local/apache/htdocs/test.txt': Read-only file system

Already tried this:

mount -o remount,rw /usr/local/apache/htdocs

That gives me this error:

mount: can't find /usr/local/apache/htdocs/ in /etc/fstab or /etc/mtab

How can I upload my folder to /htdocs?

I am pretty new to linux/server/ssh. So I hope you guys can help.

Thank you so much!

I think it is might not possible to change the folder as it is builded in firmware.
The way to use SSL certificate might only go SSL page and create self-sign certificate and provide to third-party certification authority do 2nd sign, then import it back to NSA325 v2.
