Chapter 2 Installing a PIX Firewall
Software Installation Notes
Follow these steps to download an image over TFTP using the monitor command:
Step 1 Immediately after you power on the PIX Firewall and the startup messages appear, send a BREAK
character or press the Esc (Escape) key.
Note If you are using HyperTerminal with Windows 95, you can press ctrl-break to
activate a BREAK or press the Esc (Escape) key. Depending on which service
pack is installed, Windows NT HyperTerminal may not be able to send a BREAK
character, but the Esc key should work. Refer to the Windows NT documentation
for more information.
The monitor> prompt appears.
Step 2 If desired, enter a question mark (?) to list the available commands.
Step 3 Use the interface command to specify which interface the ping traffic should use. If a PIX 515 or a
PIX 525 have only two interfaces, the monitor command defaults to the inside interface.
Step 4 Use the address command to specify the IP address of the PIX Firewall unit’s interface.
Step 5 Use the server command to specify the IP address of the remote server.
Step 6 Use the file command to specify the filename of the PIX Firewall image. In UNIX, the file needs to be
world readable for the TFTP server to access it.
Step 7 If needed, enter the gateway command to specify the IP address of a router gateway through which the
server is accessible.
Step 8 If needed, use the ping command to verify accessibility. If this command fails, fix access to the server
before continuing.
Step 9 Use the tftp command to start the download.
