connecting to U.S.Robotics MAXg ADSL gateway over SSH

Hi,
Does anyone know if it is possible to connect to U.S.Robotics MAXg ADSL
gateway router over SSH?? I tried many times from putty, but error occures
"Connection refused". Telnet is working properly. SSH serwice is turned ON.
Any ideas?

 

I don't see any indication that it supports management via SSH. Do you have
any reason to believe that it does?

The user guides and reviews that I saw indicate management support for HTTP
and Telnet, but no mention of SSH. Coupled with your "connection refused"
results, I'd say that management via SSH isn't supported.

For device management or simply protocol passthrough?

 

Thank you for reply. Maybe you're right. But i don't understand what for is
SSH in the servicess, if the router does not support it.

Access Control - Services
You can control access to various Internet services for local network
systems (LAN) and the Internet. For example, to allow remote access to your
router select the HTTP Internet check box.

Services LAN Internet (WAN)
FTP
HTTP
ICMP
SNMP
SSH
TELNET
TFTP

 

At this link, <http://support.usr.com/support/9108/9108-ug/wui_internet.htm>
they are talking about 'protocol passthrough', which can be simplified if
you break it down into the three pieces: ingress, transit, and egress.
Access control happens at the ingress point, as in, 'is this particular type
of traffic allowed into the device?'.

They give a poor example when they use HTTP there, because the HTTP
connection can be terminated in the device itself, for device management
purposes, but for HTTP and the others it's more helpful to think of them as
a question of whether they are allowed to pass through the device or not,
and if they are allowed, it's a separate question for whether each protocol
is allowed only from the LAN side, only from the WAN side, or from both
sides.

Bottom line, they are allowing you to configure whether SSH traffic should
be allowed to pass through the device, and if so, from which direction(s)
will it be allowed (LAN, WAN, both). It doesn't mean you can terminate an
SSH connection at the device itself.

You could install nmap[1] and do a port scan to see what's on offer.

Other things to look into:
- SSH may require "remote management" is also be enabled
- SSH server may be running on a non-standard port (22 is default)
- SSH server may only be listening on outward-facing NIC

Also, it's possible that encryption is available via telnet; some telnet
servers and clients support it, though it generally works best if they
are both sourced from the same project.

Good luck!

I have made some experiments and noticed, that - just like you said - SSH is
not supported.

 

Alright, thanks for reporting on your results.
