I'm new to linux.
Below is the issues that I have trouble with. (Ubuntu 17.04)
- Root Password: I don’t know the root password, so I login as user; “$sudo -i”, and then “$passwd” to change the root password. It shows password updated successfully. However, when I tried to login as [email protected], it shows permission denied. You can see the details from below pictures.
- Another problem I found is, when I tried to access the server at home, (without using school’s wifi UCM catNet) “ssh [email protected]” I can’t access it. I could only access the server by specifying its ip address “ssh [email protected]”. How can I solve it. Thank you so much for your helps.
