Internet connectivity in Arch Linux

[MailYouLater]

I've been trying to figure out how to get the Arch Linux image to be able to connect to the internet the way the Linux 3.18 image does, but I can't figure it out. I found an old issue which indicates that the Arch Linux image could connect to the internet previously, but running udhcpc (as is done for the Linux 3.18 image) tells me -bash: udhcpc: command not found, running busybox udhcpc (because the udhcpc binary on the Linux image is a symlink to a busybox binary) tells me udhcpc: SIOCGIFINDEX: No such device, and running dhcpcd -w4 (as described in #23) results in this:

dev: loaded udev
no valid intervaces found
timed out
forked to background, child pid \<number\>

I've tried several times to dig into this more, but I'm having difficulty understanding it.

There's a net.sh script that does the right thing for you. One needs to run modprobe ne2k-pci before dhcpcd. The reason for this is that the Arch Linux image is restored from a memory dump, and if the driver was already loaded everybody would get the same MAC address.

D'Oh❗️❗️
I've been trying to figure this out off and on for over a year, Digging into the source code of different parts of the Linux kernel and not being able to figure this out. Now it all makes sense. Thank you so much. I can hardly believe that in all that time I didn't notice the ~/net.sh script there. 🤦‍♂

Perhaps you could mention ~/net.sh at

v86/index.html

Line 24 in 289b803

- A complete Arch Linux restored from a snapshot, additional files are loaded as needed<br>

similar to how you have udhcpc mentioned at

v86/index.html

Line 30 in 289b803

- With internet access, telnet, ping, wget and links. Takes about 60 seconds to boot. Run <code>udhcpc</code> for networking. Exchange files through <code>/mnt/</code>.<br>

and/or add a start up script to the Arch image that echoes a statement about ~/net.sh to the terminal, similar to how you have the Linux 3.18 image mention udhcpc, as I doubt I'm the only person who didn't notice it.

Thank you.

I'll close this, I think the script is pretty self-explanatory.
