Help Can I create another ROOT ssh login on my server? Someone has access to it

  • Posted January 31, 2015

Hi please I need help I had someone install my sever configure and set up. The server is running very slow.

The server is running NGINX with virtualadmin control

He configured SSA for me which I do not feel comfortable with because he has root access.Can I delete the ssh he created and create another one.

Bottom line I do not want this person to have access to my servers what do I do. Also with the issue of slowness how do I fix it. My shared hosting plan else where are running faster than the VPS I feel he may have not configured it properly



did you run top to check what application/services are taking up the RAM/CPU?

If all you want is to block him from the server, just do

sudo passwd <User>

To see what processes are slowing down your server, do

sudo apt-get install htop

and then


You will be able to see which processes are taking up the most of your CPU and/or RAM.
