Need to setup SSH somehow

[alexdavidson]

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?

[kniteowl]

As of the moment, it uses the same key as the N5200. I don't know if this will change in the future or not.

Really? I tried that one. Applied to the v2 firmware package, it didn't yield a gzip file.

[kniteowl]

Just tried it again and it works just fine. How are you decrypting the file.

As I don't have a 1U4500, other than just decrypting the firmware and seeing what is in it, I don't have much else to go with.

If the 1U4500 has the same module menu as the N5200, let me know if you want to test and I can make an update to the SYSUSER & SSH module from Omega for you to test.

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.

edit:

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 just posted a link to a way to enable SSH access on the 1U4500.
I added it as a new thread as it follows a different approach than the way you are going after it in this thread.

If a mod etc. thinks it should be moved into this thread please do so.

Thanks

Just thought I'd point out that the N5200 firmware packages here look like they work with the 1U4500 too. But I'm not sure. I have not run any against mine.

They do seem to work in the same way as the v2 beta firmware, but I'm not inclined to try them against the NAS currently doing duty as the company's primary fileserver.

hello guys,

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.

thanks for your help
