Question

Is there any way to know from which host I have connected?

host1> mysql -h10.10.10.10 -uroot -pPassWd

I connect to host2 from host1

How do I know from which host I am connected?

Update:

I do not want to know TO which host I am connected, but FROM which host I am connected.

The answers that work via current_user() won’t always work. If the user can connect via a wildcard, it’ll return something like root@% or someuser@10.1.5.%

user() returns the user as it’s connected, while current_user() returns the user as it was defined. So you can get your hostname like this:

SELECT trim(mid(current_user(), position('@' in current_user())+1, 255))

The host that you are connecting to can be retrieved like this:

SELECT @@hostname
