I am running a 2.6.21 kernel on an ARM architecture with iptables
version 1.3.6. Iptables support is compiled into the kernel as modules:
ts7000:~# lsmod | grep iptable
iptable_filter 2368 0
ip_tables 10952 1 iptable_filter
When I try to use iptables I get an error:
ts7000:~# iptables -L
iptables v1.3.6: can't initialize iptables table `filter': Bad file
descriptor
Perhaps iptables or your kernel needs to be upgraded.
This is the first time I have used iptables. Is there something else
that needs to be done before I can run the above command?
I am constrained to use the kernel (although I can reconfigure it and
rebuild it), as it was custom-configured for my platform, but I tried to
manually build and install version 1.4.9.1 of iptables and received the
same error. I also read that the "Bad file descriptor" error can
sometimes mean file system corruption, so I ran fsck on the file system
and it is clean.
If anyone can suggest things to try to resolve this problem, I'd be very
grateful.
Thanks,
Don
