Hi Alexandru and 郭涛,
Attached is the Makefile I made for python-iptables. I can work around
this by hardwiring library locations in the source of python-iptables,
but I'd rather do it the correct way. To reproduce this build an OpenWrt
system with this Makefile and then just create a simple Python script
with 'import iptc'.
I am cloning OpenWrt from Github and running make menuconfig;make to
build everything. My Github version is about 6 days old with the last
commit at 5ba298c.
I also found that /proc/sys/kernel/modprobe contains /sbin/modprobe,
while the modprobe binary is at /usr/sbin/modprobe. According to the
Debian man page on proc(5), /proc/sys/kernel/modprobe should point to
the modprobe binary. Googling about seems also to suggest that this file
should contain the location of the modprobe binary. So I would say this
is also a bug.
Thanks!

Hey Andrew & 郭涛
Sorry I did not answer sooner.
@Andrew: do you have a Makefile for the python-iptables packages ?
I'd like to try to build it and see the issue. Or, are you just using
that .py file ?
Can you give a bit more input on which Python version you're using,
and which OpenWrt version?
If the issue is still present in the current packages trunk, I'd like to fix it.
And if 郭涛's fix works, we can apply it to trunk.
Thanks
Alex

I also meet this issue.

Hi OpenWRT Devs,
I'm building an OpenWRT package for python-iptables for a project I'm
working on and getting this error message when attempting to use it.
import iptc
File "/usr/lib/python2.7/site-packages/iptc/__init__.py", line 10, in
<module>
from ip4tc import (is_table_available, Table, Chain, Rule, Match,
Target,
File "/usr/lib/python2.7/site-packages/iptc/ip4tc.py", line 13, in
<module>
from xtables import (XT_INV_PROTO, NFPROTO_IPV4, XTablesError, xtables,
File "/usr/lib/python2.7/site-packages/iptc/xtables.py", line 677, in
<module>
_optind = ct.c_long.in_dll(_libc, "optind")
AttributeError: 'NoneType' object has no attribute '_handle'
You can view xtables.py here if you're curious.
https://github.com/ldx/python-iptables/blob/master/iptc/xtables.py
The problem is that my python-iptables package cannot find libc functions
using ctypes.util.find_library(). I've tried building OpenWRT using both
musl and eglibc but neither work. I've also tried building OpenWRT with
objdump and ldconfig. When I include ldconfig via 'make menuconfig' it
doesn't actually populate my OpenWRT image with an ldconfig binary. Maybe
this is the problem?
This bug report looks similar to my problem, but it's about MIPS and marked
as closed.

Any help or pointers would be much appreciated.
Thanks,
Andrew

define Package/python-iptables/description
Python-iptables provides a pythonesque wrapper via python bindings to iptables
under Linux. Interoperability with iptables is achieved via using the iptables
C libraries (libiptc, libxtables, and the iptables extensions), not calling the
iptables binary and parsing its output. It is meant primarily for dynamic
and/or complex routers and firewalls, where rules are often updated or changed,
or Python programs wish to interface with the Linux iptables framework.
