That's weird as the relevant line in the script does add a newline by
having the double quote closed on the next line:
for NS in $NMSRVRS ; do
R="${R}nameserver $NS
"
done
echo -n "$R" | /sbin/resolvconf -a "${dev}.openvpn"
In order to debug this further, would you mind running those commands
(as root) and share the output:
ls -l /etc/resolv.conf
for f in /etc/resolv.conf /run/resolvconf/interface/*; do
echo "pre $(basename $f):"
cat "$f"
done
TRUNCATE_NAMESERVER_LIST_AFTER_LOOPBACK_ADDRESS=no \
foreign_option_1='dhcp-option DNS 4.2.2.1' \
dev=tun0 script_type=up \
/etc/openvpn/update-resolv-conf
for f in /etc/resolv.conf /run/resolvconf/interface/*; do
echo "up $(basename $f):"
cat "$f"
done
TRUNCATE_NAMESERVER_LIST_AFTER_LOOPBACK_ADDRESS=no \
foreign_option_1='dhcp-option DNS 4.2.2.1' \
dev=tun0 script_type=down \
/etc/openvpn/update-resolv-conf
for f in /etc/resolv.conf /run/resolvconf/interface/*; do
echo "down $(basename $f):"
cat "$f"
done
Thanks,
Simon
