Hi
I builded jool in my old system without dkms. but I have some issues
1- instance name beginning "??" characters
2- instance looking netfilter but I wrote iptables.
3- When I execute the iptables command with jool, iptables returning
error. There is not any error message at dimesg.
jool kernel modules are builded 64bit arch with my custom kernel.(attached)
I builded jool userspace tools 32bit arch like my iptables tools.(I
can't attach because too big for mail size.)
I patched(attached) for build problem. I don't know those patches are
correct.
I know this is complicated. But I must be run in this system.
Are there any suggestions for me?
