Hi friends,
Total newbie here, so forgive me.
I’m trying to add functionality to iptables so I can use the BBB as a ad-hoc “router”, sharing it’s Ethernet connection with others.
From what I’ve gleamed so far I need to add that functionality by recompiling the kernel.
So following the links at http://www.angstrom-distribution.org/ i cloned the setup-scripts.
MACHINE=beaglebone ./oebb.sh config beaglebone
MACHINE=beagleboard ./oebb.sh update
. environment-angstrom-v2013.06
bitbake -c menuconfig virtual/kernel
I then change the options I need, but when I built it made a zImage file… Which confuses me.
Now what I don’t understand is that the image I want should be based off the regular systemd image.
-
bitbake systemd-image
How do I update the kernel configuration from the systemd image without just building the regular image?
A step-by-step explanation would be awesome, cause I’ve never customized/built the linux kernel before.
I also do not have a serial cable yet. Is this necessary for running a custom kernel? Do options in u-boot need to be changed?
I’m sure I’m asking all the wrong questions, but would really appreciate some help!
Here are the options that I need:
Networking ---->
Networking options ---->
Network packet filtering framework (Netfilter)--->
Core Netfilter Configuration ---->
<*> Netfilter connection tracking support
<*> Netfilter Xtables support (required for ip_tables)
<*> "NFLOG" target support
<*> "conntrack" connection tracking match support
<*> "state" match support
IP: Netfilter Configuration --->
<*> IPv4 connection tracking support (required for NAT)
<*> IP tables support (required for filtering/masq/NAT)
<*> Packet Filtering
<*> REJECT target support
<*> Full NAT
<*> MASQUERADE target support
<*> Packet mangling
