The easiest way to perform administration on a remote Linux computer is via a command-line interface. The telnet command has traditionally been used to obtain a command-line shell on remote UNIX and Linux servers across the network that run a telnet server daemon. Nearly all operating systems today, such as Windows, Macintosh, and UNIX, come with a telnet command.?Once the telnet daemon has been configured, you can connect to it from a remote computer. Simply specify the host name or IP address of the target computer to the telnet command and log in as the appropriate user and password. A shell obtained during a telnet session runs on a pseudoterminal (a terminal that does not obtain input directly from the computer keyboard) rather than a local terminal and works much the same way a normal shell does. You can execute commands and use the exit command to kill the BASH shell and end the session.?Although the telnet, rlogin, rcp, and rsh commands can be quickly used to perform remote administration, they do not encrypt the information that passes between computers. Secure Shell (SSH) was designed as a secure replacement for these commands that encrypts information that passes across the network. To connect to a remote Linux computer running sshd, you can use the ssh command followed by the host name or IP address of the target computer. Your local user name will be passed to the server automatically during the SSH request, and you will be prompted to supply the password for the same user on the target computer.

Assume the development environment is Unix workstations, and the documentation team uses the Macintosh platform for writing documentation. The client requires the documents to be available on Windows platforms. Developers produce the design documentation using FrameMaker. The documentation team uses Microsoft Word for the user-level documentation. The client submits corrections on hardcopies and does not need to modify the delivered documents. How could the information flow between the developers, the technical writers, and the client be set up (e.g., format, tools, etc.) such that duplication of files is minimized while everybody’s tool preferences and platform requirements are still satisfied?
