It was hard to learn the suffixes, but I was able to accomplish it.                                                                                                                             <strong>Step 8<\/strong>: Correct command is <code>ls s*<\/code> because it lists files starting with \u201cs\u201d. <em>(\u22123 points)<\/em><br><em>Note: the <code>-d<\/code> option would only list directories, which is not what was asked here.<\/em><\/p>\n\n\n<a href=\"https:\/\/sites.wp.odu.edu\/alexbretana\/wp-content\/uploads\/sites\/37347\/2025\/11\/annotated-CYSE270-Assignment-2_compressed.pdf\" class=\"pdfemb-viewer\" style=\"\" data-width=\"max\" data-height=\"max\"  data-toolbar=\"bottom\" data-toolbar-fixed=\"off\">annotated-CYSE270-Assignment-2_compressed<br\/><\/a>\n<p class=\"wp-block-pdfemb-pdf-embedder-viewer\"><\/p>\n\n\n\n<p class=\"has-white-color has-midnight-gradient-background has-text-color has-background has-link-color wp-elements-b20af767f4987759fe0728da36c1a662\">Assignment 3: This was very easy as I had used vi editor before.

I enjoyed creating the users and learning how to use John the Ripper. Again, remembering all the suffixes for specific commands is difficult, but I managed.<\/p>\n\n\n<a href=\"https:\/\/sites.wp.odu.edu\/alexbretana\/wp-content\/uploads\/sites\/37347\/2025\/11\/annotated-CYSElab5-1.pdf\" class=\"pdfemb-viewer\" style=\"\" data-width=\"max\" data-height=\"max\"  data-toolbar=\"bottom\" data-toolbar-fixed=\"off\">annotated-CYSElab5-1<br\/><\/a>\n<p class=\"wp-block-pdfemb-pdf-embedder-viewer\"><\/p>\n\n\n\n<p class=\"has-white-color has-midnight-gradient-background has-text-color has-background has-link-color wp-elements-b62b23ec0cbf5789a95f2a3a7a060336\">Assignment 7: This is where it started to get a bit difficult.

I was able to get the script running, however, as the instructions along with the in-class slideshow helped a lot.<\/p>\n\n\n<a href=\"https:\/\/sites.wp.odu.edu\/alexbretana\/wp-content\/uploads\/sites\/37347\/2025\/11\/annotated-Lab8cyse270.pdf\" class=\"pdfemb-viewer\" style=\"\" data-width=\"max\" data-height=\"max\"  data-toolbar=\"bottom\" data-toolbar-fixed=\"off\">annotated-Lab8cyse270<br\/><\/a>\n<p class=\"wp-block-pdfemb-pdf-embedder-viewer\"><\/p>\n\n\n\n<p class=\"has-white-color has-midnight-gradient-background has-text-color has-background has-link-color wp-elements-5f3f71834ff15ffa9f2d9fddace77e56\">Assignment 9: This one was hard. I had to really study the slideshow and do some research to figure out why my script wouldn&#8217;t work. I was eventually able to get it to work by adding <em>sudo<\/em> to all of the lines, along with making sure the compression method was correct.<\/p>\n\n\n<a href=\"https:\/\/sites.wp.odu.edu\/alexbretana\/wp-content\/uploads\/sites\/37347\/2025\/11\/cyse270assignment91.pdf\" class=\"pdfemb-viewer\" style=\"\" data-width=\"max\" data-height=\"max\"  data-toolbar=\"bottom\" data-toolbar-fixed=\"off\">cyse270assignment91<br\/><\/a>\n<p class=\"wp-block-pdfemb-pdf-embedder-viewer\"><\/p>\n\n\n\n<p class=\"has-white-color has-midnight-gradient-background has-text-color has-background has-link-color wp-elements-2fad4db0adc26b962be9f1730c5a0a57\">Assignment 10: This one took some thinking. I was able to use the &#8220;SubnetCalculator&#8221; tool to figure most of it out, as recommended by a colleague. Note: The maximum host calculations are incorrect.<\/p>\n\n\n<a href=\"https:\/\/sites.wp.odu.edu\/alexbretana\/wp-content\/uploads\/sites\/37347\/2025\/11\/annotated-Assignment-10-Networking-Basics-and-Subnetting.pdf\" class=\"pdfemb-viewer\" style=\"\" data-width=\"max\" data-height=\"max\"  data-toolbar=\"bottom\" data-toolbar-fixed=\"off\">annotated-Assignment-10-Networking-Basics-and-Subnetting<br\/><\/a>\n<p class=\"wp-block-pdfemb-pdf-embedder-viewer\"><\/p>\n\n\n\n<p class=\"has-white-color has-midnight-gradient-background has-text-color has-background has-link-color wp-elements-1a0b7eb3ac08414aa374b75bfdcf89f8\">Assignment 11: This was really easy!
