The LiveCD supports a large variety of hardware and can be used to troubleshoot system problems on a machine where you have limited or no access. A user with limited skills can easily setup remote access [...]

SSH allows secure (encrypted and authenticated) connections between two hosts. These connections include terminal sessions, file transfers, TCP port forwarding, as well as X window forwarding which I will be covering here. X forwarding is a form of tunneling that allows you to run a GUI application on a remote machine but let you view [...]

If you do not have public key authentication enabled you will be prompted for a password. This basic format for scp is this. scp [options] [[user@]src_host1:]file1 [[user@]dest_host2:]file2 Assuming the remotehost has [...]
