Amtec (ElsagDatamag) Argo 55/95 – Take 7: Fastweb strikes back

As probably the vast majority out there already noticed, Fastweb in the past weeks has provisioned a firmware update (version 0.4.4 – we’ll came back on this) that locks out users from the interface of the Argo (web, telnet, ssh). Thanks to the user geogeo I’ve had the opportunity to take a look at the new firmware: apparently, ports (22, 23, 80, 443, etc.) are binded, but are refusing any connection (even from the Argo itself!).

A side-by-side comparison of the pre-update and post-update configurations (including firewall settings fetched with firewall dump), didn’t reveal anything relevant: the firewall, apparently, isn’t the culprit. So, in lack of other informations, we must assume that the interface has been locked out at compile time.

So, how can we regain access to the Argo? Well, in the next post we’ll talk about downgrade :)
