The BIPAC-711 ADSL router can be either connected directly to a pc or to a
hub so more than 1 pc can access the internet sharing only 1 IP with of
course, 1 account. Nothing special.
Some advantages of an ADSL router. (things an usb hasn't):
----------------------------------------------------------
-dhcp server
-must not be directly connected to a pc to work
-firewall
-can chose packet encapsulation
-VPN
-virtual server
-many more features
The "danger" with this routers is that it can be accessed via port 23
(Telnet service) and a "secret" menu can be accessed with this password.
Normally, users don't even have to know this menu exists because it was
implemented there by the router's developers for them to access some
advanced commands. Some can fuck up your router. More about that later.
Now is the good point to say that I'm really not a specialist at this kind
of machines or in networks in general. I'm just telling what info I found
and which thread it could mean to owners of such a router. (and other
routers as well I think).
Now something more about the danger I was talking about. If someone knows
your IP address and in some way can figure out you own an adsl router, this
person can telnet to your IP, enter the router's password, enter this
"secret" menu and start changing some very never-should-be-changed options.
When I first telnetted to my adsl router, it asked for the password and I
started guessing. But the guessing didn't take long. After 3 times, I had
found the correct password. It was "password".(without the ""'s) Someone
told me manufacturers always use "password" as the default password but I'm
not sure if that info is correct.
Anyway, now I was in. First thing I did was change this default password
which would make it a lot harder for anyone to just enter my ADSL router and
fuck it up.
So, first thing you should do is to change this default password in
something that is not easy to guess. ->try to use all kinds of allowed
charackters.
Access your (ADSL) router:
--------------------------
-open msdos/any shell in unix type os
-telnet to IP of router
-type into the password. BIPAC-711 password = password
-your in the router now
-type help/follow listed info to list commands
listed commands of BIPAC-711:
-----------------------------
ap atm bridge bsp buffer
bun chips config db dhcpclient
dhcpserver chips edd ethernet event
firewall flashfs httpd ip isfs
l2tp led nat oam oamcli
portcli ppp pptp restart snmp
sntpclient tftp uptime uptime version
Some of these commands have subcommands. I suggest not to use de "debug"
command that can be found somewhere there. I used it and i fucked the thing
up. Don't even know what the machine does when setting it in debug mode but
I think it's not anything good. Only the powerLED worked after executing the
command and I couldn't connect to the machine anymore. Anyway, I have a new
one now.
As I expected there are also some commands that aren't listed in the main
menu:
-------------------------------------------------------------------------------
-list
There got to be more but you just have to find them. If you found some more,
mail them to me plz. (mail below)
Default path:
-------------
router ip\\flashfs\
I started to go one dir up, but it didn't work. Have to find that out too.
With tftp, it must also be possible to transfer files to your computer and
vice versa.
I think that's all I've to say.
If you want to contact me for any reason:
