Hi All,
Please forgive me if this is a duplicate of a question asked then thousand
times before. Usually I do not post to any forums because I can search the
answer, but this one has me stumped; further, I am only seeing this in
email. I do not even have a link to the forums! (Already I feel like an
idiot.)
But, first, I JUST completed an LFS build. I gotta tell you it was a total
nerd orgasm to see successful boot into the new system on the first try. I
did it "by the book." It worked. But I have no internet! I configured my my
NIC according to the instructions with a static IP address. Was that wrong?
I think not because I get the same address behind my router with every
boot. HOWVER, I did note that when I executed the shutdown command, the
system complained about "eth0" not found as compared to the "enp3s0" as
revealed by "ip link" and carefully placed in my ifconfig.enp3s0. Should
that be "ifconfig.eth0?" Or do I need to enable dhcp on top of that?
As per the subject line, my ISP is Comcast.
You normally are pulling a dhcp address directly from the isp? I think
most users have an intermediate router.
The most common reason for no internet is not having the driver for your
nic built into the kernel. If you 'ls /sys/class/net/' you will see eth0
or something like enp3s0. It that works, you do have the right driver
installed.
To get eth0 instead of enp3s0, you should have run the script in 7.4.1.2.
Creating Custom Udev Rules. Look at
/etc/udev/rules.d/70-persistent-net.rules and adjust NAME to be eth0.
If you need a real dhcp IP address directly from your ISP, install dhcpcd
from BLFS.
