...Francisco Ramirez 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. Ch. 20 1. Edit “etc/aliases file to include the entry: root, var/logs/systemmail 2. “Cat~/. Forward”, then max@bravo.com then “/max” 3. Edit “/etc/mail/access” and add the following: “connect 192.168.1.1 relay” 4. “dnl” stand for “delete to new line”, works the same as # in shell script; it instructs the compiler to ignore any line followed by “dnl” 5. Go to content configuration on Spamassassin, then under “required spam assassin score”, change 3 to 5. 6. First, type the mail followed by the e-mail address of the recipient: mail Max@email.com, then type the subject line, then press enter. Type your message, then...

...1. What are multiuser systems and why are they successful? Multiuser operating systems allow the multiple users to access the resources of single systems at a time or at different time. It allows many users to take advantage of the computer's resources simultaneously. Some permit 100's to 1000 users to take advantage of the computer's resources simultaneously. They are successful because of the powerful, efficient, stable and secure operating systems like LINUX. It has a capability of providing each user the same data ensuring total privacy from each user even while accessed by 100's of users simultaneously. 2. What is the Free Software Foundation/GNU? Linux? Which parts of the GNU/Linux operating system did each provide? Who else has helped build and refine this operating system? The Free Software Foundation (www.fsf.org) is the principal organizational sponsor of the GNU Project. GNU developed many of the tools, including the C compilers that are part of the GNU/Linux Operating Systems. Linux is the name of an operating system kernel developed by Linus Torvalds and expanded and improved What are multiuser by thousands of people on the Internet. Torvalds’s kernel and GNU’s tools work together as the GNU/Linux Operating System. 3. In what language is Linux written? What does the language have to do with the success of Linux?

One characteristic of a free software is that the code must go along with the program. b. Users are encouraged to modify the code to make it better and share it with others. c. And lastly you can’t stop or restrict people from sharing this free software. 4. The Free Software Foundation/GNU was a project that was started by Richard Stallman who believed that giving the resources for free software was the way of the future. He also wrote the GNU kernel and system. Linux was developed by Linus Torvalds and was first introduced in September of 1991. Thousands of people world wide have helped make Linux/GNU what it is today. Unit 2: 1.
