FTP WRS<br />

Wind River Systems maintains a small archive of auxiliary software and useful<br />

information available over the Internet by FTP. Click on this command to<br />

connect to the WRS FTP server. Follow the usual conventions for anonymous<br />

FTP transfers: log in as anonymous, and provide your e-mail address at the<br />

password: prompt.<br />

Authorize<br />

The Authorize command brings up an editor 10 on the file<br />

${WIND_BASE}/.wind/userlock. This file controls overall access to <strong>Tornado</strong><br />

host tools at your site. This file employs the same simple conventions<br />

described in 3.5.2 Sharing and Reserving Target Servers, p.82 for a file to restrict<br />

a target server to a list of users: the character + to indicate that all users are<br />

authorized, or the sign-on names of authorized users, one on each line.<br />

3.7 Tcl: Customizing the Launcher<br />

NOTE: If you are not familiar with Tcl, you may want to postpone reading this<br />

section (and other sections in this book beginning with “Tcl:”) until you have a<br />

chance to read B. Tcl (and perhaps some of the Tcl references recommended there).<br />

An important reference for these examples, even if you are familiar with Tcl, is the<br />

GUI Tcl Library reference available online from<br />

Help>Manuals contents><strong>Tornado</strong> API Reference. It describes the building blocks for<br />

the user interface (GUI) shared by the <strong>Tornado</strong> tools.<br />

All <strong>Tornado</strong> tools can be altered to your needs (and to your taste) by adding your<br />

own Tcl code. This section has a few examples of launcher customization.<br />

When you consider modifications to the launcher, you may want to read related<br />

code in the standard form of the launcher. The Tcl code implementing the launcher<br />

is organized as follows (all file names below are relative to WIND_BASE):<br />

host/resource/tcl/Launch.tcl<br />

The main launcher implementation file.<br />

10. The editor specified in your EDITOR environment variable, or vi.<br />
