TFTP - Bad Magic Number?

[MJNSBF]

I need to upgrade my activation key on my Pix 501, and received that key from Cisco. However, their instructions say I must make a backup copy of current flash (via TFTP server) and then bring the image back down. I transferred the file to the TFTP server just fine. But when I try to bring it back to the pix, it gives me the following message and doesn't proceed with the reload:

Received 2384 bytes
Bad Magic Number (0x-198517a9)

Any ideas on what this means?

I've had this problem when the image file that exists in your tftp server is either corrupt or missing.I found that I received the 'magic number' message when my image file registered 0 bytes.Try recopying the file again into your tftp server and re-running the upload.

Well, I uploaded the image to the tftp server again (actually 3 different times now), and then tried to download back to the pix.....same message.

HI.

What command are you using to upload the image?

You can use another image of the OS (same or newer) that you can obtain from your Cisco dealer.

Hi Yizhar,

I used the write net command to upload to the tftp server.


Will obtaining another image from my Cisco dealer cost additional money? We just bought this 2 months ago.....

HI.

This is your problem - you are uploading the configuration file, then trying to use it as the OS image.
Good thing that the pix won't allow you that.

> Will obtaining another image from my Cisco dealer cost additional money?
It should not cost you.

If you currently have pix version 6.2x, then you can upgrade the activation key without the tftp proccess.

Thanks Yizhar!

Yes, thank goodness pix won't allow!

I have version 6.1....is there a way (command) to upload the OS, or is contacting my dealer a better way to go?

Again, thanks for your help!!!

HI.

I don't know of such command to upload the OS image. If you find one please let us know.
Ask you dealer for the file - it should be quick and easy.

MJNSBF,

Until you have 6.2 you cannot copy the OS image off the PIX. With v6.2 you can copy the OS image via HTTPS.

I believe the instruction was probably about making a backup copy of your configuration. That makes more sense since you are upgarding the OS image.
