ssh ports and auth keys

[rizzy]

Hello,
Purchased DS 110j yesterday, so far - impressive bit of kit, very happy i went with Synology.
While setting up i couldn't find options to change the default SSH port and option to use paired auth keys. I used SSH since early Redhat days and over the years come to conclusion that SSH on default port and password protection is asking for trouble.
Are there any guides/howto's on setting up SSH using custom ports and keys?
Any other vulnerabilities i should investigate before taking DiskStation online?
Many Thanks

Hi and congrats on your purchase, it really is a very nice NAS and they often update the software/DSM

I was looking for the same info, since after upgrading DSM the configuration for SSH is lost

Changing the SSH port can be done in the file

Code: Select all

/etc/ssh/sshd_config

Then search the line that says

Code: Select all

#Port 22

And change it to your own port number, don't forget to remove the #. For example:

Code: Select all

Port 99999

Make sure the port number is not in use, see the source article for more info.

Btw, I also needed to enable SSH again via the web interface after upgrading. Go to Control panel -> Terminal -> Enable SSH
