Re: [Cerowrt-devel] 6relayd

[Steven Barth <cyrus@openwrt.org>]

Hi,

I haven't really touched 6relayd since October so not sure what is wrong 
atm.
There was a problem with its init script recently due to some shell 
script change in OpenWrt which I hopefully fixed yesterday (couldn't 
verify the issue or fix yet though).

Feel free to provide me with some debugging information of the system 
while PD fails for you so I can have a look at the probable cause:

* "ifstatus ge00" (replace ge00 with your IPv6 upstream interface)
* "ip addr list dev ge01" (replace ge01 with the interface your 
downstream router is connected)
* "ps | grep 6relayd"

Anyway I will migrate all the stuff to odhcpd soon (it's successor which 
shares a good part of the codebase but is a bit better integrated with 
the rest of the environment).


Regards,

Steven
