I have successfully included apache into buildroot. Everything builds correctly and lands on the target and httpd loads when the target boots. Awesome.
I can wget from localhost on the target and download index.html, so httpd seems to be working. However, the web server does not respond to requests from external network clients. I wondered if the problem was on my LAN, but I was able to ping and even ssh into the target from those network clients. So the network seems to be OK.
In my admittedly limited experience this seemed like a firewall problem. But... there is no /etc/sysconfig/iptables and here's what iptables reports:
[root at buildroot sysconfig]# iptables --list
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
[root at buildroot sysconfig]#
It looks open to me. Can anyone suggest why the web server is only serving requests from localhost?

It might be configured explicitly to listen only on localhost, or it
might bind itself only on the interfaces that are up at the moment the
web server is started.
Do you get a "Connection refused", or does your HTTP client times out?

Oops. It may be the LAN after all. I tried from a 3rd client and it works. Not sure why I can ssh from the other two clients, but for now I can see there is no firewall problem.
Thanks for the quick reply, Thomas!
