RE: [2008.12] Anyone get iptables working?

2009-01-08 Thread Nick Van Fossen 

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

RE: [2008.12] Anyone get iptables working?

2009-01-08 Thread Joel Newkirk 
Try "opkg remove iptables" followed by "opkg install
http://downloads.openmoko.org/repository/testing/armv4t/iptables_1.3.8-r4_armv4t.opk";

Ok so the address 0x9838 is indeed inside the iptables binary which
thus has been compiled for wrong instruction set. Go build it for

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)

Very odd. teq should be perfectly legal instructions that is available

What is this? Google finds this in a list about "Cirrus Maverick
co-processor support for GCC".

   "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

[2008.12] Anyone get iptables working?

2009-01-08 Thread Nick Van Fossen 

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
