[Cerowrt-devel] Strange auto configured DNS address

[Cerowrt-devel] Strange auto configured DNS address

[William Katsak]

Hello,

I am new to the list and CeroWrt, but have been playing around quite a bit lately and am finding the project very interesting.

I am seeing a very strange phenomenon with my Mac machine using CeroWrt. I have an he.net /48 set up on the router following the instructions on the wiki…this works fine. However, when I turn on IPV6 on my Mac, it picks up two DNS addresses: the cero router IPV4 address, and for some reason, the link-local address that is shared by se00 and sw00. This address is not routable from the Mac, so the machine randomly hangs on name resolution because it sometimes tries to hit that address.

Obviously, I can fix this by forcing that address out of the resolver list, but I was just wondering if anyone else has seen this and/or can explain it.

Thanks,
Bill Katsak

One more piece of info about this...it is also happening when there is
no explicitly configured IPv6 connection in the router...e.g. fresh
firmware flash.

I haven't had time to look deeper into the IPv6 stuff on Cero yet though.

Hi Bill,

It's nice to have you on the list. I wrote the entry in the Wiki, and have tested the script with CeroWrt 3.3.8-6 (19 June 2012). I had some troubles with the later 3.3.8 versions, so I dropped back 10 and punted. 

I haven't seen the problem you mention, so I have a couple questions:

- What version of CeroWrt are you using?
- What version of OS X do you have (I'm running 10.6.8, and cannot comment on newer versions.) 

Thanks.
