DSM-G600, DNS-3xx and NSA-220 Hack Forum

Hello,
this is what I have found out during my work to set up IPv6 on 313:

1) It was not so easy
2) You have just to compile the kernel with IPv6 support turned on... and some tweaking :
It took me several hours to notice what was going wrong - ICMPv6 worked, UDP/IPv6 too - but not TCP/IPv6 - ssh or ftp hung and hung - and then using tcpdump showed that packets weren't stopped by any firewall or similar crap - it was wrong TCP checksum on every packet sent from DNS-313.
So, you have to apply the patch I made which stops the driver from unimplemented TCP offload checksumming whilst using IPv6 and then it should work.

To sum up, setting up IPv6 is simple... now - just apply the patch, enable IPv6 support, compile and upload the kernel - and it's ready.

PS. I tried compiling the kernel from openwrtstorlink.sf.net - it seems it's not yet ready to use and does not support SATA Storlink driver (only IDE Storlink) - in other words it can be compiled without the necessary drivers

PPS. If you have not read previous posts about kernel compilation:

0. You need libncurses development headers and root access for source.me
1. Get D-Link GPL sources: http://tsd.dlink.com.tw/temp/download/2 … 80128).tgz
2. Unpack it and unpack included dns313_src.tgz
3. copy the content of opt directory to /opt
4. go to Image directory
5. # source source.me
6. # cd src/kernel
7. # make menuconfig - change whatever you want, apparently ext3 support is necessary
8. # make
9. You can find the kernel image at arch/arm/boot/zImage
10. use mkimage tool found in the DNS-313 toolchain (toolchain/bin/mkimage) and cfg/kernel.cfg:
# toolchain/bin/mkimage -f cfg/kernel.cfg -d src/linux/arch/arm/boot/zImage zImage
11. Upload zImage to /.boot directory of DNS-313, reboot and hold your thumbs
