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
general
data_period = INT
Days into the past that measurements are considered valid. (Default: 5)
http_timeout = INT
Timeout in seconds to give to the python Requests library. (Default: 10)
circuit_timeout = INT
Timeout in seconds to create circuits. (Default: 60)
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.
sbws_home = STR
sbws home directory. (Default: ~/.sbws)
datadir = STR
Directory where sbws stores temporal bandwidth results files. (Default: ~/.sbws/datadir)
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)
v3bw_fname = STR
File names of the bandwidth list files. The latest bandwidth file is symlinked by latest.v3bw
state_fname = STR
File path to store the timestamp when the scanner was last started. (Default:
~/.sbws/state.dat)
log_dname = STR
Directory where to store log files when logging to files is enabled. (Default: ~/.sbws/log)
destinations
It is required to set at least one destination for the scanner to run. It is recommended to set
several destinations so that the scanner can continue if one fails.
STR = {on, off}
Name of destination. It is a name for the Web server from where to download files in order to
measure bandwidths.
usability_test_interval = INT
How often to check if a destination is usable (Default: 300)
destinations.STR
url = STR
The URL to the destination. It must include a file path. It can use both http or https.
verify = BOOL
Whether or not to verify the destination certificate. (Default: True)
country = STR
ISO 3166-1 alpha-2 country code. Use ZZ if the destination URL is a domain name and it is
in a CDN.
tor
When sbws is run as a system service ~/.sbws/tor is replaced by /run/sbws/tor.
datadir = STR
sbws' owned tor directory. (Default: ~/.sbws/tor)
control_socket = STR
sbws's owned tor control socket file. (Default: ~/.sbws/tor/sbws/control)
pid = STR
sbws's owned tor pid file. (Default: ~/.sbws/tor/sbws/tor.pid)
log = STR
sbws's owned tor directory log files. (Default: ~/.sbws/tor/log)
external_control_port = INT
tor control port to connect to. Useful to run integration tests with chutney. (Default: not
set. If set, it takes preference over the control socket)
extra_lines =
sbws's tor extra configuration. (Default: None)
scanner
nickname = STR
A human-readable string with chars in a-zA-Z0-9 to identify the scanner. (Default:
IDidntEditTheSBWSConfig)
country = STR
ISO 3166-1 alpha-2 country code. (Default: AA, a non existing country to detect it was not
edited)
download_toofast = INT
Limits on what download times are too fast/slow/etc. (Default: 1)
download_min = INT
Limits on what download times are too fast/slow/etc. (Default: 5)
download_target = INT
Limits on what download times are too fast/slow/etc. (Default: 6)
download_max = INT
Limits on what download times are too fast/slow/etc. (Default: 10)
num_rtts = INT
How many RTT measurements to make. (Default: 0)
num_downloads = INT
Number of downloads with acceptable times we must have for a relay before moving on.
(Default: 5)
initial_read_request = INT
The number of bytes to initially request from the server. (Default: 16384)
measurement_threads = INT
How many measurements to make in parallel. (Default: 3)
min_download_size = INT
Minimum number of bytes we should ever try to download in a measurement. (Default: 1)
max_download_size = INT
Maximum number of bytes we should ever try to download in a measurement. (Default:
1073741824) 1073741824 == 1 GiB
relayprioritizer
measure_authorities = {on, off}
Whether or not to measure authorities. (Default: off)
fraction_relays = FLOAT
The target fraction of best priority relays we would like to return. 0.05 is 5%. In a 7000
relay network, 5% is 350 relays. (Default: 0.05)
min_relays = INT
The minimum number of best priority relays we are willing to return. (Default: 50)
cleanup
data_files_compress_after_days = INT
After this many days, compress data files. (Default: 29)

logging
to_file = {yes, no}

to_stdout = {yes, no}
Whether or not to log to stdout. (Default: yes)
to_syslog = {yes, no}
Whether or not to log to syslog. (Default: no) NOTE that when sbws is launched by systemd,
stdout goes to journal and syslog.
to_file_max_bytes = INT
If logging to file, how large (in bytes) should the file be allowed to get before rotating
to a new one. 10485760 is 10 MiB. If zero or number of backups is zero, never rotate the
log file. (Default: 10485760)

If logging to file, how many backups to keep. If zero or max bytes is zero, never rotate
the log file. (Default: 50)

Level to log at when using files. (Default: debug)
to_stdout_level = {debug, info, warning, error, critical}
Level to log at when using stdout. (Default: info)
to_syslog_level = {debug, info, warning, error, critical}
Level to log at when using syslog. (Default: info)
