Hi folks,
The original script that retrieves all online DNS being awfully slooow, I found a modification that reduces it to ~1'30 (instead of 30') as my tests have shown that if a DNS is online, it'll answer in less a second :
cd contrib
cp resolvers-check.sh resolvers-check.sh_ORG
Then, edit resolvers-check.sh as follow :
#!/bin/bash
IMPORTANT: The following modification will not work if you leave it to: #!/bin/sh !
res=0
while read line; do
if [ "x${IPV4_ONLY}" != "x" ]; then
n=$(echo "$line" | egrep -c ',\[[0-9a-fA-F:]+\](:[0-9]+)?,')
if [ $n -ne 0 ]; then
continue
fi
fi
resolver_name=$(echo "$line" | cut -d, -f1)
# NB: Above code is unmodified - just a beacon - modif is below.
( cmdpid=$BASHPID;
(sleep 1; kill $cmdpid) & \
while ! eval "${DNSCRYPT_PROXY} -L ${CSV_FILE} -R ${resolver_name} -t ${MARGIN} -m 1"
do
:
done )
# NB: /Modification - Code below is genuine
if [ $? -eq 0 ]; then
echo "$line"
echo "+ ${resolver_name} - OK" >&2
else
echo "- ${resolver_name} - Failed" >&2
res=1
fi
done
This modification will spit a lot of gargles when running (due to the nature of the code (return code test), I did not found a way to avoid that, may be some more experienced user can do that) but it will only cost you 90s instead of… 1800s.
My ¢2.
