[Solved]Network on A toshiba protégé M800-104

Re: Network on A toshiba protégé M800-104

Okay this is getting boring

I went back to detonates post:
http://kubuntuforums.net/forums/inde...opic=3100052.0
and followed it to the dot.

except I created /etc/resolv.conf file to reflect to one I have on my desktop.

# Generated by NetworkManager
domain quicknet.ch
search quicknet.ch
nameserver 213.202.32.3
nameserver 195.162.161.182

same modem / domain so no problem (I hope)

Now when I do:

route

I get:

route
Kernel-IP-Routentabelle
Ziel Router Genmask Flags Metric Ref Use Iface
link-local * 255.255.0.0 U 1000 0 0 eth0
default dyn-cable-cust. 0.0.0.0 UG 0 0 0 eth0

On my desktop:
route
Kernel-IP-Routentabelle
Ziel Router Genmask Flags Metric Ref Use Iface

213.202.48.0 * 255.255.254.0 U 1 0 0 eth0
link-local * 255.255.0.0 U 1000 0 0 eth0
default dyn-cable-cust. 0.0.0.0 UG 0 0 0 eth0

When I do:

sudo apt-get update

It gets to the first line:
0% (connecting to ch.archive.ubuntu.com)......
and hangs for a long time and then goes on to tell me it could fetch anything.

I supose I am missing this:

213.202.48.0 * 255.255.254.0 U 1 0 0 eth0

respective to my lappy.

So I guess I am making progress here

Edit:
Progress stoped when I tried this:
Qoute from mondo:

Then try

ifup eth0

. If it says eth0 already configured run

ifdown eth0
ifup eth0

If you still get that message run

ifconfig eth0 down
ifup eth0

You need to run the second one before network-manager has a chance to mess with it.

At that point ifconfig should show an IP address for eth0 and

route

should show a default route to 192.168.0.1 and you should be able to ping your modem.

route shows:

Kernel-IP Routen Tabelle
Ziel Router Genmask Flags Metric Ref Iface

In other words: Nada

Had to do a network restart to get back to "normal".

Finally we see a little info about your network setup. Your modem is not acting a a DHCP server. You do not have an internal only network at all. Your desktop is getting a valid ip address from your ISP. Your laptop will need to do that also. Probably everything written here is meaningless in your situation. I think what you need is pppoe and pppoeconf.

Re: Network on A toshiba protégé M800-104

If you have 2 PC's hooked to the modem, you HAVE to have a router. There is no way around this.

P.S. What you can do to check to make sure everything works. Unplug the modem from the wall (AC) for about 5-10 minutes. Connect the laptop directly to the modem (no switch in between), and plug the modem back in. Allow the modem to boot completely. Then boot the laptop with the live CD...I only say the live CD so that we know any changes you might have already made will not interfere with this test.

Re: Network on A toshiba protégé M800-104

@mando
this is a cable modem going over a switch to a desktp pc, voip phone router (and yes they are hooked up correctly).
I have never had a problem hooking up other pc's or laptops to the switch (not the phone router).

I never said it was an internat network.
It was always cablemodem->switch (not router, no firewall / proxy)->pc, laptop, etc.

what do I need pppoe and pppoeconf for??
I haven't touched that stuff in over 10 years.

Re: Network on A toshiba protégé M800-104

If you have 2 PC's hooked to the modem, you HAVE to have a router. There is no way around this.

It is just a swtich with 8 ports.
They have always connected directly (plug and play) with other machines.
We are missing something here.

If it has it own IP address I don't know about it.

I will shut it off for 5 min. and connect directly (see what happens.

Re: Network on A toshiba protégé M800-104

technically you should be able to connect through a switch, as long as it is one device at a time. It is even possible I suppose that your ISP had an error, and handed out multiple IP addresses, but that is unlikely.

What a router does is provide you with an inside network with private IP address' (typically in the 192.168.x.x range), and 1 global IP address (also referred to a 'routable' IP address). All traffic from the inside network gets to the outside world via the routable IP address, using NAT (Network Address Translation), and visa-versa.

When you just have a switch, there is no way to use NAT.

Re: Network on A toshiba protégé M800-104

@musicman. No problem.

The solution was so simple.

I had to to turn OFF the modem and the switch and restart them.

Thank you. I should have thought of that my self.

But with only one brain cell left and three business to run.

Thankx all and I will write a synopsis on this for others to profit from.

Off to my b-day party

Re: Network on A toshiba protégé M800-104

Awesome! Glad you got it sorted! It's funny how the solution to most technical problems is more often than not the easy one!

Re: Network on A toshiba protégé M800-104

Yeah you get stuck in the proverbial woods and forget the trees :P

Thankx again all.

Edit:
Now for the wlan (wifi) part. I'll open a separate one for that and then write a whole synopsis.

Re: Network on A toshiba protégé M800-104

I was just about to suggest rebooting your modem.

The modem "thinks" it has already assigned an IP to our computer, and won't assign another. Rebooting it makes it renegotiate the settings. This happens to me every time we have a power failure.
