Communication

   
finger user@host
displays the finger information for user at the machine host. Most finger servers display the files .project and .plan if they exist in their home directory. Note that these files must be publicly readable, hence if you'd like to create your own .plan for others to see, you must have a symbolic link in your home directory to a publicly readable directory.

 

telnet host
allows you to remotely login to another computer.

   

ftp host
file transfer program enables files to be uploaded and download to and from other computers. Many sites allow anonymous users to login in and download files. Use the command get to retrieve files, but be sure to set the proper type with the binary and ascii commands. Logout simply by typing bye.

 

who
lists users logged into your machine.

 

talk [user]
sends request to user to talk. If they respond with talk yourname, then a connection is established. Use CTRL L to redraw the screen and CTRL C to quit.

 

NEWS
Use the apropos command to list installed news readers. In addition, you may find gnus (invoked from Emacs) and netscape to be convenient. Be sure to read the man|Info|help pages before reading news for the first time, otherwise you will spend a loooong time waiting for the news reader to subscribe you to the bazillion Usenet newsgroups. Also be sure to read up on Usenet etiquette, so you don't become one of the bajillions wasting other's time posting their drivel. Unless, of course, you're looking to get flamed.
