Directory /root permitssion denied

[Rui Wang]

Hi Max,

I am currently using the window system and have run a session successfully after completing the necessary installations. However, I have encountered some errors the next day when creating clients in the putty as attached (e.g. no such file or directory: '/root/.zu/prefix). Upon investigating further via FileZilla, I do not appear to have the necessary permissions to access the root file. I am unsure why this is the case, considering I have been using my key to log in. I have tried multiple times, even creating new instances, but still faced this issue.

Would you be able to help me with resolving this problem? I would highly appreciate your help.

Thank you,
Rui

Are you running ./start_session_simple.sh using sudo? That would be incorrect.

Many thanks, Max! I will try to run ./start_session_simple.sh without sudo

Hi Max,

Thank you so much for your response. It works! 

Additionally, I think should run ./kill_all.sh without sudo to end a session as well, right? Would you mind talking a little bit about when should I use sudo and when should not? I have looked up some information on Google, but I'm still a bit confused. I would really appreciate it if you could explain this to me.

Best,

Rui

You should never use sudo with z-Tree unleashed once your server is up and running.
