From 61ecb465b1c803316cb55bae0c2d7cf3c0008589 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Mon, 15 Feb 2016 18:40:02 +0100 Subject: resolved: turn on DNSSEC by default, unless configured otherwise Let's make sure DNSSEC gets more testing, by defaulting DNSSEC to "allow-downgrade" mode. Since distros should probably not ship DNSSEC enabled by default add a configure switch to disable this again. DNSSEC in "allow-downgrade" mode should mostly work without affecting user experience. There's one exception: some captive portal systems rewrite DNS in order to redirect HTTP traffic to the captive portal. If these systems implement DNS servers that are otherwise DNSSEC-capable (which in fact is pretty unlikely, but still...), then this will result in the captive portal being inaccessible. To fix this support in NetworkManager (or any other network management solution that does captive portal detection) is required, which simply turns off DNSSEC during the captive portal detection, and resets it back to the default (i.e. on) after captive portal authentication is complete. --- src/resolve/resolved.conf.in | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/resolve/resolved.conf.in') diff --git a/src/resolve/resolved.conf.in b/src/resolve/resolved.conf.in index efc9c6733a..a288588924 100644 --- a/src/resolve/resolved.conf.in +++ b/src/resolve/resolved.conf.in @@ -16,4 +16,4 @@ #FallbackDNS=@DNS_SERVERS@ #Domains= #LLMNR=yes -#DNSSEC=no +#DNSSEC=@DEFAULT_DNSSEC_MODE@ -- cgit v1.2.3
