  1. Finding people • finger command • finger user@hostname • Finger command generally works on local network • It may not work on other networks. • You cannot finger username@wam.umd.edu from outside of wam.umd.edu. • finger –l gives more information.

  2. Finding Site Owners • Whois command used to find who owns a site. • 2-step process: • Type whois hostname to find whois server • Type whois –h (whois server name) hostname • Eg: whois cnn.com • Then whois –h whois.networksolutions.com cnn.com

  3. Whois 2 • Access .gov whois files differently • http://www.nic.gov/whois.html • Don’t put the www in front of the domain. • Other country domains • www.nic.uk/whois.html -- United Kingdom • www.nic.fr/whois.html -- France • General site for country-specific domains: • http://world-whois.com

  4. Lynx • Text-based browser • lynx www.umd.edu • Up-down arrows scroll among links • Left = back, right = forward • Enter = click on link • Space = pagedown, - = pageup • G = go to another site • Q = quit

  5. Lynx bookmarks • Type a then d. • That will save a bookmark. • To use the bookmark, type v to view them and then select one.

  6. Entry forms • Let you enter data and send it to the server. • Can be buttons, text, dropdowns, etc… • Can cycle through form elements using tab. • Can hit enter or click on a certain send button to send this data.

  7. Searching • Use search engines to find webpages • Start searches simple. • Make them more specific only as necessary. • Search engines have programs that search the web for pages and data. • Not all data is webpages • www.invisible-web.net

  8. Searching • Type some keywords into the space given. • The search engine will look for pages with those keywords • Some require AND’s between words, some don’t (like google). • The results will be displayed.

  9. Displaying Search Results • Generally the results appear as a list of links. • There may be several pages of results. • There may be short excerpts from the document. • There may be a cache. • There may be options to download. • There may be other links or suggestions on the page.

  10. Subject Indexes • Example: Yahoo • Hierarchical menus that let you find the subject you want. • Eg, Tennis elbow : • Health ->Diseases ->Sports ->Tennis Elbow • Search by idea rather than by exact phrases.

  11. Meta searches • Metacrawler searches other search engines for your query • It waits a few seconds, then displays the top results from each • Can be useful since different search engines use different methods for finding and categorizing pages.
