NAME

       sbws.ini - Simple Bandwidth Scanner configuration

DESCRIPTION

       Tor bandwidth scanner configuration file.

       sbws   (1)   scanner   command   requires  a  configuration  file  with  the  "[scanner]",
       "[destinations]" "[destination.<name>]" sections.

       There must be at least one "[destination.<name>]".

       See an EXAMPLES below for a minimal configuration.

SECTIONS

              data_period = INT
                     Days into the past that measurements are considered valid. (Default: 5)

              http_timeout = INT

              reset_bw_ipv4_changes = {on, off}
                     Whether or not to reset the  bandwidth  measurements  when  the  relay's  IP
                     address  changes. If it changes, we only consider results for the relay that
                     we obtained while the relay was located  at  its  most  recent  IP  address.
                     (Default: off)

              reset_bw_ipv6_changes = off
                     NOT implemented for IPv6.

       paths
          When sbws is run as a system service, ~/.sbws is changed to /var/lib/sbws.

          v3bw_dname = STR
                 Directory where sbws stores the bandwidth list files.  These are the files to be
                 read by the Tor Directory Authorities.  (Default: ~/.sbws/v3bw)

       destinations
          It is required to set at  least  one  destination  for  the  scanner  to  run.   It  is

              url = STR
                     The URL to the destination. It must include a file path.  It  can  use  both
