From 047cbcf5df11cc7f72d1f1fe683a80d313896242 Mon Sep 17 00:00:00 2001 From: Indrajit Raychaudhuri Date: Tue, 26 Dec 2023 10:30:49 -0600 Subject: ddclient: T5144: Warn against configuration with broken IP lookup service We always enable HTTPS in ddclient configuration, however `http://checkip.dyndns.org` is HTTP only and does not support HTTPS. Warn the user if they are using this service. Also, make `url` in `web-options` mandatory. --- src/conf_mode/dns_dynamic.py | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) (limited to 'src') diff --git a/src/conf_mode/dns_dynamic.py b/src/conf_mode/dns_dynamic.py index 809c650d9..99fa8feee 100755 --- a/src/conf_mode/dns_dynamic.py +++ b/src/conf_mode/dns_dynamic.py @@ -15,7 +15,7 @@ # along with this program.
