A tale of two kernels: I have two kernels: one was installed by Debian and one
I compiled from a .config file that has previously worked great on my
computer for many kernels. lsmod says both kernels have the same eepro100
module loaded when they are running, and DHCP loads on boot for both. When I
boot from the one installed by Debian, I can ping out. However when I boot
from the one I compiled, I can't ping out.
ericdeb:~# ping 68.56.0.5
PING 68.56.0.5 (68.56.0.5): 56 data bytes
ping: sendto: Network is unreachable
For the bad kernel, here's what ifconfig outputs:
ericdeb:~# ifconfig
eth0 Link encap:Ethernet HWaddr 00:02:B3:9A:40:3B
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:74 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
RX bytes:7234 (7.0 KiB) TX bytes:0 (0.0 b)
Interrupt:5 Base address:0x6000
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:64 errors:0 dropped:0 overruns:0 frame:0
TX packets:64 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:4276 (4.1 KiB) TX bytes:4276 (4.1 KiB)
Conversely, here's what the good kernel's ifconfig says:
eth0 Link encap:Ethernet HWaddr 00:02:B3:9A:40:3B
inet addr:4.8.41.173 Bcast:4.8.63.255 Mask:255.255.224.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:132 errors:0 dropped:0 overruns:0 frame:0
TX packets:154 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
RX bytes:28268 (27.6 KiB) TX bytes:15742 (15.3 KiB)
Interrupt:19 Base address:0x1000
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:64 errors:0 dropped:0 overruns:0 frame:0
TX packets:64 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:4276 (4.1 KiB) TX bytes:4276 (4.1 KiB)
So I don't get the "inet addr: ..." line with the bad kernel. Any hints on
what might be going on that makes one kernel have internet connectivity and
the other not? Everything is the same between them as far as I can tell. Oh
yeah, back to the tale of two kernels: I want to behead the good kernel,
because it has all those extra modules I don't use, but I can't sacrifice the
bad one for it because it doen't have internet working, just like the book.
Thank you for any ideas you may have. -Eric
