DNSCrypt overview

Shows dnscrypt-proxy's query_log in a nice graphical way by parsing its content with mtail.

How to use

  • Download and install mtail
  • Configure DNSCrypt-proxy daemon running to generate the query_log in ltsv format
  • Save the content of the following mtail “program” to a text file
# mail "program" for DNSCrypt's query log (in ltsv format)
# Sample line:
#  time:1608044190 host:  message:www.ripe.net    type:A  return:PASS                                                                       cached:0        duration:1      server:faelix-ch-ipv4
