[SOLVED] debian 7 on a machine with windows 7 and openSUSE 12.2

Here's an idea: try them both.

Hi,
Neither works , it connects through ifupdown instead of wired, and it has the same value as I set in the interfaces file !
I feel so frustrated, I use linux since 2005, and in Mandriva never encountered such a thing .
I just want it to work.

thanks,

what do you mean by that? After editing /etc/network/interfaces what command are you running to bring the interface up?

So bringing the interface up does work? What are you actually doing and what what happens?

What are you encountering exactly?

After edition the interfaces file I restart the NetworkManager, by /etc/init.d/network-manager restart.

In the NetworkManager and under wired, there are two options ifupdown(eth0) and DSL, it refuses to connect through DSL, but succeeds to connect to the ifupdown, and it has the same IP and netmask like those on the interface file.

When I boot into debian 7, sometimes it connects successfully into DSL, and after about an hour the connection drops, and any attempt to reconnect later fails.

Where is the DSL connection coming from? How is your router set up and how is it connected to your computer?

lin66uxx · 05-29-2013, 03:44 AM

Hi,
I created the DSL connection using graphical tool(which I don't remember its name), under system -> network -> DSL, there are the options to create wired, Broadband,VPN ... .

How is your router set up

I don't know what you mean .

It is connected to my computer through a cabel to the ethernet card.

cynwulf · 05-29-2013, 03:56 AM

Why would you you create a DSL connection if you're not using a DSL modem? If the router is not connected by a USB port or set up to run in bridged mode, then you are probably not using a DSL connection.

lin66uxx · 05-29-2013, 03:59 AM

I am sorry, actually I do use a DSL modem, it is D-Link DSL 2500U.
Regarding bridge connection, I am not expert, but what I do know, is that, I don't have the option to set my username and password through the IP asddress of the modem, but rather while creating the DSL connection.

cynwulf · 05-29-2013, 04:20 AM

Well the wifi connection is not much use to you with that router/modem...

It does seem to be a router and supports, NAT, PPPoE, PPPoA and bridged. I suggest reading the manual and getting it set up to allow you to connect via ethernet (not as a DSL modem).

I read through the link above, but could not find any useful information as to how to connect?

cynwulf · 05-29-2013, 04:56 AM

Read the manual which came with your router/modem or hunt for it online...

etc

lin66uxx · 05-29-2013, 08:56 AM

Hi,
OK, so I read through the link below, I managed to understand that to set the username and password I get from the ISP I have to choose a different WAN option rather than Bridged, is that write?
Next I am not sure which option to choose, is it PPPoA or PPPoE ? (page 17)
Third if my router ip address ends with 138, from where does my IP address starts from and till where it ends ?is it 139-254 ?
Also what is PPPoE service name? is it the name of ISP?

Any help is greatly appreciated ?

OK the bridged mode (not the same thing as a bridged modem) is correct - don't mess with that. The device is a router and DSL modem, it it is not a modem and you should not be trying to set up network manager to use it as a modem. I would advise that you just get rid of network manager and set up your connection using the networking daemon. You won't see any benefit from using network manager if you don't have a wireless connection.

Stop and disable networkmanager (for now)

Code:

# /etc/init.d/network-manager stop

Code:

# update-rc.d network-manager disable

Edit /etc/network/interfaces as follows

Code:

# The loopback network interface
auto lo
    iface lo inet loopback
# The primary network interface
auto eth0
    allow-hotplug eth0
    iface eth0 inet dhcp

(ensure your primary interface is called eth0 if it's eth1, substitute with that etc)

Restart networking daemon (not network-manager)

Code:

# /etc/init.d/networking restart

You should see "dhcpdiscover" and then a connection.

If there is a problem, you need to post the full output and the contents of /etc/network/interfaces

lin66uxx · 05-29-2013, 10:20 AM

Hi,
network-manager has no option to disable, only stop,restart,start,status... .
What modification shall I do to the router through its IP?
Here is the output I get, I delete the MAC address of my eth0 and the IP of the router .

Well from that output - it's working...

If the IP addresses you're hiding starts with e.g. 192.168.x then there is no point in hiding them as they're supposed to be private addresses - that's the whole idea of a NAT router.

Can you ping the router?

e.g.

Code:

$ ping x.x.x.138

(substitute the full gateway address)
If yes can you ping a hostname?

Code:

$ ping google.com

If not can you ping the IP address for that hostname?

Code:

$ ping 173.194.41.64

Post output

Code:

$ cat /etc/resolv.conf
