I want to use an existing Ubuntu machine (with a public IP) to allow a user to SSH into it and then use it to SSH/RemoteDesktop/FTP into another linux machine (with a private IP but within the 1st machine's network).
I would create a new user account for this purpose, but I want to:
- Restrict sudo access to this user
- Not be able to go into other users /home/otheruser directory
How to do it?
