File Transfers

I have a problem, I am currently trying to transfer two of my files from my main computer to the pwnbox server in Hack The Box. I tried dragging and copy/paste none of these work. Please Help

You need to use scp command.

From you machine:
scp nomefile username@ip_pwnbox:/dir_pwnbox

The username and password of Pwnbox is on Desktop of the Pwnbox, the Ip Address of you Pwnbox you can retreive with command ip addr | grep inet

If you use a Windows machine, you can download pscp from putty website or grafical tools like Filezilla
