Installing and Recovering PIX Firewall Software

Get the Boothelper Binary Image

Use the following steps to download the Boothelper binary image:

Step 1 Log in to Cisco.com and continue to the PIX Firewall software directory, as described in the previous

section, “

Downloading Software from the Web” or “Downloading Software with FTP.”

Step 2 Download the latest Boothelper image (bh5nn.bin; where nn is the latest version available) from

Cisco.com and prepare a diskette as described in the sections that follow.

Note The Boothelper installation only supports PIX Firewall Version 5.1, 5.2, 5.3, 6.0, and later. After

Boothelper downloads the PIX

Firewall image via TFTP, it verifies the checksum of the image.

If it is not Version 5.1 or later, it displays the message “Checksum verification on flash image

failed” and reboots the PIX Firewall.

Step 3 Download the PIX Firewall software binary image file pix6nn.bin (where nn is the latest version

available) from Cisco.com and store this file in a directory accessible by your TFTP server.

Preparing a Boothelper Diskette with UNIX, Solaris, or LINUX

Follow these steps to prepare a Boothelper diskette:

Step 1 To prepare a UNIX, Solaris, or LINUX TFTP server to provide an image to the PIX Firewall, edit the

inetd.conf file to remove the # (comment character) from the start of the “tftp” statement.

Step 2 Determine the process ID of the current inetd process.

Step 3 Use the kill -HUP process_id command to kill the process. The process will restart automatically.

Step 4 Use the dd command to create the Boothelper diskette for the PIX Firewall unit. For example, if the

diskette device name is rd0, use the following command.

dd bs=18b if=./bh510.bin of=/dev/rd0

This command copies the binary file to the output device file with a block size of 18 blocks.

Note The diskette may have a name other than rd0 on some UNIX systems.

Step 5 Eject the diskette, insert it in the PIX Firewall diskette drive, and power cycle the unit. Alternately, if

available, use your unit’s Reset switch, or enter the reload command from the PIX

Firewall console. The

PIX

Firewall then boots from the new diskette.
