About 'Remote Login' how to logout that?
Thanks all guys!

I just solved it by myself HeHe!
I think is simple error that I don't know Terminal.app too much.
The cause of problem is I command this

ssh &lt;username&gt;@&lt;hostname_trough_remote_login&gt;


and I didn't know how to logout, so It's just simple way to logout. use 

exit


It's solved. (first I used logout)
