Yep, they probably provisioned a new default configuration.
As I wrote, from my point of view, the easiest solution is try to access via serial port. Do you have a backup of your previous configuration?

I’d like to stress a bit on this: I’m pretty confident that, if you regain access to the web interface, and apply the steps described here
http://lab.algasystems.net/2012/01/amtec-elsagdatamag-argo-5595-take-4-hardening/
your configuration is safe also after a reboot – at least, mine hasn’t been touched right now.

They also did a reset of the router to the default config. So they deleted any personal config I did apply to the router (first of all, I turned upnp on and configured more than 25 ports forwarding).

Ok. The problem is when you power off and then you restart the router. Each time he downloads the configuration from the server of Fastweb. So every time you have to enter the serial for the remake access to the WebConfig.
Must somehow make the change, ultimately.

Hi Derring,
yes, apparently Fastweb delivered an updated configuration. My router is still reachable (this seems to indicate that the hardening strategy is more or less working, at least), so I’d need someone with the new configuration and an RS232-TTL converter, that accesses to the router via the serial port and gets the new config. Having that, restore the access to the webinterface *should be* a relatively easy task – I hope.

Hello Bano. As you probably knows, Fastweb have blocked connection from public IP and for internal IP so we can’t log on our Argo anymore. Do you know any workaround? Thankx.

I edited the post, adding the rg_conf and rg_factory areas. I somewhat removed the sensitive data (almost: I’m sure there are still some mac addresses in rg_conf).
Hope these can be useful. There’s a forum, or a blog where I can read more about your porting efforts?

I need the adsl version because the ethernet driver in this one crashed when I try to use it (and I need the adsl driver too). rg_conf is compressed by deflate and relatively simple to decompress but is not so easy recreate the rg_config header after an edit. I try to port on Alice Gate Voip Wifi, Bbox and Livebox2 because the argo’s firmware/kernel is the best one.

Hi purputy, I already tried to fetch the ARGO55 one, but unfortunately the filename seems to be different. Maybe the version numbering is not the same – even tough the firmware must be very similar (excluding the ADSL modules).
For what about factory and rg_conf areas, I’ll try to put them online ASAP. I’m a bit doubtful about rg_conf, since it appears encryped (there’s no plain text data in it, apart from the ‘rg_conf’ header). Do you have further info about its format?
Also, out of curiosity, on what architecture are you porting the firmware to?

Hi,
I try to port this very good firmware to another similar architecture but it crashed because I’m not able to recreate the factory area and the config one. Somebody can share this two flash zone? It is very simple to remove sensitive data just change user and password from webif and mac adress with an hexedit on the factory backup. Another question… I’m not a fast*eb user and I haven’t access on the firmware update server can somebody share the last firmware image for argo55 (I think the webadress is like this: https://update.elsagdatamat.com/ or this: http://59.0.121.191:8080/ACS-server/file/ED_ARGO55_1.3.19.kit )
Thankyou…
