[2008.12] Anyone get iptables working?
So, with 2008.9 I was using iptables to tether my ubuntu laptop to my freerunner's gprs connection. But as of 2008.12 I'm getting an Illegal instruction error each time I run the iptables command. Commands I run on the freerunner to enable tethering after gprs connection: iptables -v -A POSTROUTING -t nat -j MASQUERADE -s 192.168.0.0/24 sysctl -w net.ipv4.ip_forward=1 I've noticed that most but not all iptables commands generate the same Illegal instruction error as well. Has anyone got around this yet? I've installed iptables, iptables-utils, and upgraded libgcc1 to v4.2.4-r5.1 from the angstrom repository. -Nick _ Windows Live™ Hotmail®: Chat. Store. Share.

Which instruction is it? Use the following to find out 1) gdb --args iptables -v -A POSTROUTING -t nat -j MASQUERADE -s 192.168.0.0/24 2) run 3) backtrace 4) x/5i $pc 5) info register Better Cc: me on your reply since I might not notice your reply on the mailing list due to heavy traffic :-) ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

What is this? Google finds this in a list about Cirrus Maverick

the following are patches for gas, ld, opcodes, and bfd-- for the
Cirrus DSP arm copprocessor (arm9e).

Where did you get these? :-) Please run
1) gdb --args iptables -v -A POSTROUTING -t nat -j MASQUERADE -s 192.168.0.0/24
2) run
3) shell cat /proc/`pidof iptables`/maps
so that we see what library comes with this __strtoull_internal

Like I said, I got iptables and iptables-utils from angstrom by adding the
angstrom repo using instructions at
http://wiki.openmoko.org/wiki/Repositories by creating the
/etc/opkg/angstrom-feed.conf file per the 2008.8 instructions
near the top. Then I used commands opkg update followed by opkg install
iptables iptables-utils. This also
updated the libgcc1 package, since iptables required a newer version than the
openmoko repo contained. (this includes the libgcc_s.so.1 file mentioned below)

RE: [2008.12] Anyone get iptables working?
Ahh dang I should have checked my e-mail again earlier. I followed Timo's
suggestion to rebuild from source, and that worked like a charm. But your fix
would have saved me a bit of time. If anyone wants an ipk of iptables v1.4.2
let me know :)
Thanks everyone

Try opkg remove iptables followed by opkg install
http://downloads.openmoko.org/repository/testing/armv4t/iptables_1.3.8-r4_armv4t.opk;
