Cable cnxn not working (eth1) on MDK10.0 Official[One machine, just Internet access]
 

Hi,

To explain the slightly obscure subject: I'm not installing a network, I just want a singular machine to access the Internet via my external Cable modem with Cat-5 cable connection (I tried USB but that didn't work either)

I've been using Linux on and off since MDK9.1, which auto configured my PCI Ethernet card and network a charm. However, after scrapping my dual-boot of 9.1&XP for a clean, single boot of MDK10 Official, I have never had any luck with configuring the network correctly.

Unlike some other pitfalls I've searched these forums for, I don't get 'Bring up interface ethX [FAILED]' on boot. (I did, but I fixed that now).

My sole problem is that I can't access anything via my new connection, and the Connections Monitor in the Control Centre seems to be receiving and sending, yet, the status bar says that the connection is not active ('Not Connected').

Clicking the 'Connect' button results in a long process which eventually results in a supposed successful connection attempt, but which still leaves me without access to the Internet. (Konqueror says it couldn't find hostname for every request)

I'm thinking perhaps I configured the network wrong, it's not the same this time around as the comfortable 9.1 auto detection. ;) My ISP refuses to give tech support to Linux users, but doesn't block them off the network, so asking them is of no use, but I have no idea what to put as my DNS and Gateway IPs in configuration. I hazarded a guess at 82.0.0.2 and .1 respectively (as suggested by the wizard; Let's say my IP is 82.42.12.34) but to no avail (I did reboot).

I just don't understand why the auto-detection and -cfg of 9.1 doesn't work this time around.

My card is a RealTek 8139. I have checked for the module using lsmod and 8139too is listed. eth0 is a SiS onboard Ethernet adaptor, and well, SiS sux0r, so I'm going with the PCI RealTek instead. ;)

Thanks. Help Appreciated. :)



Edit: I've just done a tracert on this machine to the MDK10 machine, and apparently the connection is live. It's just getting MDK to recognise it. If anybody knows how to get gateway and DNS info out of my ISP I'd be very grateful. :)

BTW dhcpd is the DHCP server which provides the info. dhclient or pump are client applications that receives the IP address from the server.

Some cable modems remember the network interface MAC and will not assign an IP if it does not match. So if you swapped from the builtin to the Realtek then you will need repower the modem i.e. assuming you used the builtin when 9.1 was installed.

The DNS info will be provided by DHCP so you do not need to enter an address.

Check top or ps to see of dhclient or pump is running.

I solved it. I looked into the issue of MAC addresses, and my ISP has done some changes which means I couldn't register the new MAC; However, all that was needed was a reboot of the modem under the new NIC in order for that NIC'S MAC to be accepted on the network, although it wasn't quite the *modem* remembering the MAC, it was my ISP.

But all is well now, thanks! :)
