Repeat after me: Running ANY permission command on / without knowing exactly what you're doing is a great way to break your system. Even if you know what you're doing, it's still probably the wrong thing to do. In your case, the command won't work because it's the wrong one to start. Secondly, groups are a very valid Linux construct of users, and blocking ...

Why not use Desktop Sharing? This is a front end for VNC, which will allow you to easily start up a Video Session (I guess that is the point of your question). Personally I'd stay away from things like Teamviewer (it works, but security, Wine, authentication speak against it)

The option ClientAliveInterval does exactly what you want, it basically sends pings in the specified interval (in seconds) and kills the connection if it doesn't receive an answer. To control how fast it kills the connection, you can use ClientAliveCountMax, which is the maximum number of pings to send without receiving a response before considering the ...

scp -P 24 /home/aa/video/a.mp4 user@222.222.222.222:/home/aa/video/a.mp4.new The "P" is upper case. You don't need to worry about the "local port", scp can access the filesystem directly, it doesn't need the network for it.

You do not have to mention a source port, it will be a auto-generated (>=1024). Also to mention a custom port number use -P option, -p is to preserve metadata. Do: scp -P 24 /home/aa/video/a.mp4 user@222.222.222.222:/home/aa/video/a.mp4.new

If you have no physical access to the hardware, no web-based control panel, and there is no operating system whatsoever on the machine, then I don't know of any way to install an operating system on it remotely. If you were able to install an operating system on this computer over the internet, so would anyone in the world with its IP address -- and ...

You can use ssh -O FingerprintHash=md5 user@host to use old-school MD5 hashes, or store this in your ~/.ssh/config: FingerprintHash md5 You server is probably using old openssh version which does not support new sha256 hashses.

It depends on how you have set up networking in Virtualbox between the host and the guest. The two most common set-ups are NAT or Bridged. In the NAT (Network Address Translation) case you will have to set up port forwarding to access the guest from your host. AFAIK, this is the default for Virtualbox and you will likely be using that if you have not ...

In Ubuntu, the default SSH policy is "Deny root login via SSH directly, except by SSH Key Authentication only." This is done by the PermitRootLogin without-password line of /etc/ssh/sshd_config. You can enable root password login over SSH by changing that line to say PermitRootLogin yes. However I must caution you - this permits brute forcing attempts ...

To have X11 forwarding working, you need to have xauth installed on the remove server. Verify it is there. There should probably be also some guide in the server error log, complaining about missing executable or so.
