[Cerowrt-devel] Upgraded to 3.10.38-1, DNS issues?

[Aristar]

I didn't specify any DNS servers so I guess it was using my ISP's dns
servers (verizon FiOS). As I said I didn't realize DNSSEC was enabled
by default now. but even with it disabled it doesn't seem to work out
of the box anymore without a manually set resolv file.

dnscrypt-proxy is working great though (without needing a resolv
file), it runs as a daemon and sets up an encrypted connection to
OpenDNS servers which you then specifcy 127.0.0.1#2053 for dns
forwarding. I suggested this be added to CeroWRT awhile ago but there
wasn't much interest, nor any official packages available, though that
thread I linked above in this thread has a repository and a maintainer
in the forum thread with a source repo.
