SonicOS 5.8.1 Administrator Guide
Using the SonicWALL graphic as an example, you would take the following steps:
Step 1 Start XVI32 and click File > Open to open the graphic image GIF file.
Step 2 In the left pane, mark the first 50 hex character block by selecting Edit > Block <n> chars…
and then select the decimal option and type 50 in the space provided. This will mark the first
50 characters in the file, which is sufficient to generate a unique thumbprint for use in a custom
match object.
Alternatively you can mark the block by using
the following sequence:
• Click on the first character (#0).
• Press Ctrl+B.
• Click on the character in position #49.
• Press Ctrl+B.
To locate the character in position #49, click on a character in the right pane (the text pane) and
then look at the bottom left corner for the decimal address. Try different characters until it shows
Adr. dec: 49. Note that you must click on the corresponding location in the left pane before you
press Ctrl+B to mark the block.
