Short takes: SSH, custom ports, root and Synology NASs

This content is 7 years old. I don't routinely update old blog posts as they are only intended to represent a view at a particular point in time. Please be warned that the information here may be out of date.

This blog has been much maligned of late… I’d like to get more time to write and I have literally hundreds of part-written posts, some of which are now just a collection of links for me to unpick…

In the meantime, a couple of snippets that may be useless, or may help someone one day…

Using SSH with a custom port number

My Synology NAS complains about poor security if I leave SSH enabled on port 22. It’s fine if I change it to another port though (security by obscurity!). Connecting then needs a bit more work as it’s ssh user@ipaddress -p portnumber (found via the askubuntu forums)

Logging on to a Synology NAS from SSH as root

On a related topic, I recently needed to SSH to my NAS as root (not admin). ssh root@ipaddress -p portnumber¬†wasn’t authenticating correctly and then I found Synology’s advice on how to login to DSM with root permission via SSH/Telnet. It seems I have to first log on as admin, then sudo -i to elevate to root.
