Unit 5 assignment 1
Ch. 18 1. Sftp-secure file transfer protocol is a network protocol that provides file access, transfer, and management over a trusted data stream.
Scp-secure transfer protocol is a network protocol that transfers data that can withstand or is immune to interception and tampering. 2. Use the “ssh host who” command in the terminal to show who is logged in 3. Scp user@bravo:-r your@home:blank 4. “$ ssh plum xterm” or use this command with “-y” if x11 forwarding is not trusted 5. The problem that enabling compression prevent when using a ssh to run remote x11 applications on a local display would be that this creates a backup feature. Should the computer crash, all of your work will be saved on the hard drive. 6. Check with the remote administrator to see if something has changed.
