Issue Weird side-effects when disabling root login

amba1980

New Pleskian
1.

I have a well working system, if I allow root access for ssh

PermitRootLogin yes

without any restrictions.

As soon as I add

Match Address 127.0.0.1

I cannot login any longer using ssh *at* *all*. Not from the outside (as expected) but also not using the Plesk UI using

Tools & settings > SSH Terminal: root

I only get a dialog pointing to the KB article I used for the restriction above


How to get root access to work through the Plesk UI from localhost only?

2.

As soon as I disable outside root login

PermitRootLogin no

I get weird side effects (email sending stops working) and other things. Not sure why.

Any thoughts would be appreciated.
 
The "weird side effects" have not been seen in connection with Plesk yet, so probably it is purely an operating system issue or something that your hoster's support needs to take care of.
