I've read about the modules the N5200 uses for this. I guess the 1U4500 would use a similar system, although I've been unable to figure out the key used to encrypt the firmware upgrade package.
If it's like the N5200, it'll be a 56-bit DES CBC key generated from an alphanumeric password, and we have the first three bytes of the plaintext (GZIP header). How was the key for the 5200 determined?

There's no module management menu on the 1U4500. There's a Firmware Upgrade entry on the System menu, though.
I can't remember how I decrypted this last time. Since Ubuntu appears not to have a 'des' package, I must have used something like 'openssl des -d -K 2006N5200 -in <input>.bin -out <output>.tar.gz', but that's giving me 'bad magic number' now.
Aaargh, just discovered that openssl isn't actually compatible with the des command! That'd be it. Now, where can I get something that is compatible...
i've a brand new 1U4500, flashed with the new firmware version 2.00.04. With the description of Tom i get access to the filesystem, and i could see, that the module pages are existing, although they are not permitted to use over the webpage. So i'm not able to ad the ssh module.
kniteowl is it possible to modify the firmware in that way, that the module pages could be used? How can i decrypt the original firmware to see what's in it with my mac.
alexdavidson I tried it too over the openssl package of my mac, and i got the same error message. Have you figured out a solution.
