If you do need to initialize your environment, this is typically done using a command at login time. The form of this command depends on what shell (command interpreter) you use on the WAVE host. To identify your shell, log onto the WAVE host and type `echo $SHELL'. If the response contains the characters `csh', you are using the C-shell (or a variant of it); in this case, use `source /usr/bin/cshsetwfdb' to initialize the environment. Otherwise, use `. setwfdb' to do so (don't omit the `.' in this case). Usually, the appropriate command is included in your `.profile' or `.login' script on the WAVE host, so that it need not be entered each time you log onto the WAVE host. See setwfdb(1) (type `man setwfdb' on the WAVE host) for further information.
This is probably a command of the form `ssh atlantic'. You will probably be prompted to enter your password when you execute this command. If you don't have ssh on your computer, and an ssh server on the WAVE host, it is very strongly recommended that you obtain and install them (both are freely available from http://www.openssh.org/). Use telnet only as a last resort, and never on a public network.
