Name

speedtest - Speedtest CLI by Ookla is the official command line client for testing the speed and performance of your internet connection.

Version

1.0.0

Synopsis

    speedtest [-aAbBfhiIpPsv] [--ca-certificate=path] [--format=[=format-type]] [--help] [--interface=interface]
    [--ip=ip_address] [--output-header] [--precision=num_decimal_places] [--progress=yes|no]
    [--selection-details] [--server-id=id] [--servers] [--unit=[=unit-of-measure]] [--version]

Description

speedtest is an application that measures the latency, jitter, packet loss, download bandwidth, and
upload bandwidth of the network connection between the client and a nearby Speedtest
Server.

Options

-h, --help
Print usage information
-v
Logging verbosity, specify multiple times for higher verbosity (e.g. -vvv)
-V, --version
Print version number
-L, --servers
List nearest servers
–selection-details
Show server selection details
-s id, –server-id=id
Specify a server from the server list using its id
-o hostname, –host=hostname
Specify a server from the server list using its hostname
-f format_type –format=format_type
Output format (default = human-readable)
Note: Machine readable formats (csv, tsv, json, jsonl, json-pretty) use bytes
as the unit of measure with max precision.

format_type values are as follows:
- human-readable human readable output
- csv comma separated values
- tsv tab separated values
- json javascript object notation (compact)
- jsonl javascript object notation (lines)
- json-pretty javascript object notation (pretty)
–output-header
Show output header for CSV and TSV formats
-u* unit_of_measure***, --unit*** unit_of_measure*
Output unit for displaying speeds (Note: this is only applicable
for ‘human-readable’ output format and the default unit is Mbps)
- bps bits per second (decimal prefix)
- kbps kilobits per second (decimal prefix)
- Mbps megabits per second (decimal prefix)
- Gbps gigabits per second (decimal prefix)
- kibps kilobits per second (binary prefix)
- Mibps megabits per second (binary prefix)
- Gibps gigabits per second (binary prefix)
- B/s bytes per second
- kB/s kilobytes per second
- MB/s megabytes per second
- GiB/s gigabytes per second
- auto-binary-bytes automatic in binary bytes
- auto-decimal-bytes automatic in decimal bytes
- auto-binary-bytes automatic in binary bits
- auto-binary-bytes automatic in decimal bits
-a
Shortcut for [-u auto-decimal-bits]
-A
Shortcut for [-u auto-decimal-bytes]
-b
Shortcut for [-u auto-binary-bits]
-B
Shortcut for [-u auto-binary-bytes]
-P decimal_places –precision=decimal_places
Number of decimal_places to use (default = 2, valid = 0-8)
-p yes|no –progress=yes|no
Enable or disable progress bar (default = yes when interactive)
-I interface –interface=interface
Attempt to bind to the specified interface when connecting to servers
-i ip_address –ip=ip_address
Attempt to bind to the specified IP address when connecting to servers
–ca-certificate=path
Path to CA Certificate bundle, see note below.

Output

Upon successful execution, the application will exit with an exit code of 0. The result will include
latency, jitter, download, upload, packet loss (where available), and a result URL.

Latency and jitter will be represented in milliseconds. Download and upload units will depend on the output
format as well as if a unit was specified. The human-readable format defaults to Mbps and any machine-readable
formats (csv, tsv, json, jsonl, json-pretty) use bytes as the unit of measure with max precision. Packet loss is represented as a percentage, or Not available when packet loss is unavailable in the executing network environment.

The Result URL is available to share your result, appending .png to the Result URL will create a
shareable result image.

Example human-readable result:

$ speedtest
    Speedtest by Ookla
 Server: Speedtest.net - New York, NY (id = 10390)
    ISP: Comcast Cable
Latency:    57.81 ms   (3.65 ms jitter)

Download:    76.82 Mbps (data used: 80.9 MB)
Upload:    37.58 Mbps (data used: 65.3 MB)
Packet Loss:     0.0%
Result URL: https://www.speedtest.net/result/c/8ae1200c-e639-45e5-8b55-41421a079250

Network Timeout Values

By default, network requests set a timeout of 10 seconds. The only exception to this
is latency testing, which sets a timeout of 15 seconds.

Fatal Errors

Upon fatal errors, the application will exit with a non-zero exit code.

Initialization Fatal Error Examples:

Configuration - Couldn’t connect to server (Network is unreachable)

Configuration - Could not retrieve or read configuration (ConfigurationError)

Stage Execution Fatal Error Example:

[error] Error: [1] Latency test failed for HTTP

[error] Error: [36] Cannot open socket: Operation now in progress

[error] Failed to resolve host name. Cancelling test suite.

[error] Host resolve failed: Exec format error

[error] Cannot open socket: No route to host

[error] Server Selection - Failed to find a working test server. (NoServers)

SSL Certificate Locations

By default the following paths are checked for CA certificate bundles on linux machines:

/etc/ssl/certs/ca-certificates.crt
/etc/pki/tls/certs/ca-bundle.crt
/usr/share/ssl/certs/ca-bundle.crt
/usr/local/share/certs/ca-root-nss.crt
/etc/ssl/cert.pem

If the device under test does not have one of the above mentioned files, then the canonical and up to date CA certificate bundle provided by the curl project can be manually
downloaded into a specific location. This specific location can be provided as a parameter per the following example:

wget https://curl.haxx.se/ca/cacert.pem
./ookla --ca-certificate=./cacert.pem
