[gentoo-user] Trying to install a cable modem connection

[Jeff Cranmer]

I have recently been attempting to connect to Roadrunner cable using my Linux box.
According to their login instructions, it should be possible to connect it to the service without requiring a password (Roadrunner systems apparently used to have a custom login script which made Linux installs even more of a pain.

I have successfully emerged dhcpd.  I have not attempted to put dhcpd in my startup scripts.

First, after plugging in the cable box and typing adsl-stop to disconnect my adsl connection, running ifconfig yields the following:

eth1      Link encap:Ethernet  HWaddr 00:04:5A:5E:42:FE
          inet6 addr: fe80::204:5aff:fe5e:42fe/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:1777 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1912 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:1249796 (1.1 Mb)  TX bytes:232302 (226.8 Kb)
          Interrupt:11 Base address:0xe800

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:14 errors:0 dropped:0 overruns:0 frame:0
          TX packets:14 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:700 (700.0 b)  TX bytes:700 (700.0 b)

I have a broken eth0 connection on the motherboard which is disabled, so this info is correct.

I then edit /etc/conf.d/net as follows:
#iface_eth1="up"     ---   added # to comment out the config required by rp-pppoe
config_eth1=( "dhcp" )     --- added the dhcp configuration required by the cable modem,

running the command /etc/init.d/net.eth1 start yields the following:

* Starting eth1
*   Bringing up eth1
*     dhcp
*       Running dhcpcd ...                                               [ ok ]
*       eth1 received address 24.88.247.205

ifconfig now reports

eth1      Link encap:Ethernet  HWaddr 00:04:5A:5E:42:FE
          inet addr:24.88.247.205  Bcast:255.255.255.255  Mask:255.255.255.0

Here's where I get a little stuck.  My internet programs are not recognising this eth1 connection.  What step do I need to perform in order to get the internet connection working?

Thanks in advance
