iptables can't initialize iptables table `filter': Bad file descriptor
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
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 18.104.22.168 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.
getsockopt failed strangely: invalid argument
As an update, someone suggested that there might be an issue with EABI vs. OABI on the ARM platform, so I reconfigured iptables with --enable-static and --disable-dynamic, since I think that there is not an issue as long as iptables doesn't try to build linking to the EABI-built kernel libraries. After rebuilding, I tried to run "iptables -L" again and this time received a different error:
"getsockopt failed strangely: invalid argument"
As before, if anyone has any suggestions on how I might resolve this error to get iptables working, I'd be very appreciative.
I have met the same problem, would you please let me know if you have solution finally?
