[URGENT] Internet connection problem w/ bamboo 'n' cable modem
 

Hi!

I cannot connect to internet with my ISP's cable modem. This doesn't seems to be a modem problem or even a Ethernet card problem since I already saw many questions in several sites mentioning the same. So I did try to :study: it first before bothering halfworld :rolleyes:

Odd enough, no useful reply is given, not even in Mandrake Expert :confused:

Many reported that with the same machine that now gives them probs it did worked fine with 9.0. And also mentioned by others and by myself that everything works smoothly in M$ Windows 2000 PRO or XP :mad:

Mandrake's Control Center reports eth0 is up, configured for dhcp with the correct driver (8139too), no IP Address defined and Internet Access Type = lan.

ifconfig shows 3 entries. lo, eth0 with appropriate HWaddr but no IP address and also an entry for eth0:9 with the same HWaddr as eth0. This also has a inet addr of 169.254.211.159.

Where did this come from? There is no ifcfg-eth0:9 in the network-scripts. I manually configured resolv.conf for my ISP (as mentioned in one of the few prob replyes I found) to no avail.

And also I think it is important to mention that when 9.1 is booting it hangs on "Bringing up interface ETH0" (close wording). It will eventually pass as [OK] and continue.

Then, when I open the Mandrake Control Center to view network config, it says the eth0 is up but no IP address is listed. The network config is using DHCP. And it cannot connect to Internet on testing connection.

The most funny part is that in the cablemodem the "Status" LED is On; and the "Cable" and "PC" LEDs blink when MCC try to connect or even if I try to /sbin/dhcpcd -dBH eth0 on command line.

Of course, PINGging is absolutly useless since it always returns a "No host found" message :(

Anyone know what might be going on. What did change between 9.0 and 9.1 in this area?

Thanks in advance.

When ifconfig reports an IP of 169.254.211.159 it means dhcp was not set up correctly.

Fire up MCC (Mandrake Control Center) and click on Network & Internet > DrakConnect > Wizard. At this point check that "Use auto detection" is enabled and while your at it "Expert Mode", click Next.

If LAN connection is selected, deselect it and choose instead "Cable connection", click Next.

Now your asked which dhcp-client you want, the default should be "dhcp-client, run with it, click Next. At this point it might install some packages, relax.

Now your asked if it detected the correct NIC, if so say No to having another one and click Next.

Now on this page you can choose if your box will use a host name assinged from the DHCP address it will soon get and start at boot. If those are ok, run with it, click next.

This page needs no explination, click next.

This page needs no explination, click next.

Again, this page needs no explination. The rest you can cypher.

On a side note. I do not know why but I have had to reboot the machine to get this to work. I have tried restarting dhcpd, network and anything else I thought needed but nothing work as I said without rebooting.

Didn't work
 

I've even removed all DHCP packages :(

Reboot, Halt, Shutdown, Restarted... nothing worked.

Result:
Dunno what to do more :cry:

Tomorrow (today, later) I will re-install Mandrake and follow your instructions with a clean new system.

I will post results... but if you have (or anyone else) other ideas they are welcomed.

If other files contents needed just ask.

The Saga continues...
 

Well!

I did the fresh install. Now I changed from "lan" to "cable" when the "summary" screen appeared in the instalation process. Everything seems to go well but...

When entering the system it reverted to "lan", so I tryed once more changing it throughout MCC without aparent success :cry:

I reboot it and I noticed a fast message that appeared on screen for a brief moment:
or something like that. I mean, the text was not with this exact words but it said that I don't have rights to modify /etc/resolv.conf

This gives someone a light on the problem :Pengy:

I'm a :newbie: so please be explicit :D

:cool: Lopo

Re: The Saga continues...
 

Check the permissions on /etc/resolv.conf. Doesn't make sense really since you have to be root to run MCC so root should have write access to resolv.conf.

That puzzles me.

net oddity
 

Hummm!

This turns odd and odd...

Guess!?!?...

/etc/resolv.conf has 644 - root - root and zero bytes :D

It looks like a joke but it isn't :(

Do you know what configuration files should I modify by hand to make it work? And what do their "insides" should look like?

Best and thanks,

:cool: Lopo

Re: net oddity
 

Well since it is only complaining about resolv.conf I would change the permiisions of it to be the same as the other files in /etc. The contents should look like this;

search this.is.your.isp.domain
nameserver 192.168.1.1
nameserver 192.168.1.2
nameserver 192.168.1.3


The name servers are the primary, secondary and ternary DNS servers used/provided by your ISP. If your using a firewall/router just log into it and hunt around for that information. If not then call your ISP and find out what those are for your area.

It didn't work
 

Hi!

It didn't work :cry:

I think that it should be something else VERY wrong in my system and I dunno what. :(

Below is a screenshot of MCC DrakConnect in portuguese, but things are in the same place ;)

http://pwp.netcabo.pt/0652324702/images/drakconnect.png

Shouldn't Tipo (Type) be "cable" instead of "lan"?
Shouldn't Protocolo (Protocol) be "dhcp" instead of "static" hence I don't have a static IP address but a dynamic one?

Hope you can help. If need more screenshots please ask.

Thank you very much,

:cool: Lopo

Are you running Mandraqke at "Paranoid" security level? Maybe it set the "immutable" bit on /etc/resolv.conf.
(man chattr)

Re: It didn't work
 

Yes is should say cable instead.

Hmmm, hadn't thought of that.

Re: Re: It didn't work
 

Where the hell can I change it :D
And "Protocol"? Did you saw the pic?

I don't know :eek: When I installed I set it to the lowest level... but I have shorewall installed and in MCC it as the option to allow all requests from internet checked and I uncheck it (that was when shorewall was installed).

Does this mean that I turn it "Paranoid"?

Best and thanks for you precious help :)

One more little thing...
 

One more little thing...

If you feel in the mood to post a step-by-step mini-how-to for dummy :newbie: s my data - token from MsWindows IPCONFIG - to access the Cable ISP is:

DNS Server: netcabo.pt
IP Address: 81.84.129.29
Subnet Mask: 255.255.254.0
Default Gateway: 81.84.129.254

If this could be of any use and if you are willing to do it ;)

Best again,

:cool: Lopo

Run up MCC, go to DrakConnect. Click Expert Mode then Wizard.

Auto detection should already be checked, also enable Expert Mode, click Next.

Deselect LAN connection and click on Cable connection, click Next.

Click dhcp-client then Next.

Click Next.

Again Click Next.

You should now be at the window to assign a static IP. Enable Automatic IP. If you do not want the host name to be something relating to your IPSs domain then deselect "Assign host name from DHCP address" and on the "DHCP host name line enter what you want your box host name to be, then click Next.

If you want to use Zeroconf then enter the host name of your box. Same for Host name (FQDN). Click Next and Next.

Once it is done restarting the network you should end up back at the first display of Drakconnect.

At the top click Configure Internet Access and enter the gateway IP (81.84.129.254).

Now click on Conifgure Local Area Network. Delete the IP and Netmask if there. Check the Boot Protocol is DHCP and start at boot. Click Ok.

Clcik Apply and then Ok. Restart the system. I know you should have to restart the machine but I have not been able to get this sort of connection working without one.

Nope :cry:

Spending a full night awake looking to Mdk and going back and forth from Linux machine to Windows machine was not my idea of starting my birthday :(

Latter I will post an URL to a small page with explained screenshots of all steps I took so you can see if there is something wrong. I also had screenshots from DrakSec and DrakFirewall ;)

Bye and "see" you later.
