Error when trying to "Send Message" to Alert Contact "Unable to send a test message"
After some time it displays a message box with "Unable to send a test message".
I've restarted the nas.
I've tried a Microsoft email address instead of a gmail address.
Emails have been sending...

itnorm: Did you remove the cable from lan port 2 as I suggested above?

Yes, cable removed.
Thanks, again.
Can local ssh and remote ssh use different ports?
- StephenBMay 23, 2019Guru
They both use 22 in the NAS, but you can forward a different port in the router to port 22.
That's a reasonable idea, but it won't eliminate the threat of hacking - it just lowers the odds a little.

I'm not trying to eliminate the threat of hacking. There is a remote NAS that uses rsyncoverssh to send backups to the NAS in my office and it is running all the time on port 22. I would like to do a local ssh at the same time without interfering with the rsyncoverssh. If I connect locally thru putty and ssh with port 22, will it interfere with the remote NAS using port 22?

It won't interfere.
It's easy to test - try opening putty twice, and make two ssh connections to the NAS. It works fine, even if both instances of putty are running on the same PC.
