where port is the TCP socket on which the client can communicate with the server. On UNIX systems, you can add this command to cron. On Windows 95/98/NT systems, this command can be run as a console application.

When NoSecurity is specified, the bcmnbrus command allows connections from all IP addresses. Otherwise, only those client IP addresses listed in the/usr/3Com/common/data/allow file will be accepted by Upgrade Link.

For security, an administrator can enter the IP addresses of only those clients who will be allowed to upgrade devices. An allow file is an ASCII text file containing the IP addresses of clients to upgrade devices. The allowed file looks like the following:

129.213.100.151

129.213.100.152

139.87.172.100

When NoAuthentication is specified, the bcmnbrus command allows the remote client to access the server without user authentication, see “Settings Page” on page 28 for a description of the available settings.

■Then, to access Upgrade Link from a web browser, enter the following URL: http://<server_nam>:<port>/

Do not resize the browser window while the Upgrade Link application is running.

 

CAUTION: Only one client at a time should access the Upgrade Link Server.
