sys-cmd wget

sys-cmd wget sends an HTTP or HTTPS request to an address from the route table selected in WEB-CLI and takes the content of the response. It is used to see the content of a health address or a version page quickly on the screen; in situations where the headers and the TLS detail are needed, curl offers more options.

Command Summary

TR7 WEB-CLI · sys-cmd wget

# type wget and press Tab: a free parameter

admin@TR7LBWAF01> sys-cmd wget

<wget-parameter-1>

 

admin@TR7LBWAF01> sys-cmd wget -qO- <address>

admin@TR7LBWAF01>  

Everything written after the word wget is passed to the tool as it is. There is no mandatory field; if the content is to be seen on the screen, -qO- is written.

How It Works

Subject	Behavior
Context	The request is sent from within the selected v-device and route table.
File	If -O- is not written, the tool tries to write the content to a file in its own working area; this file does not land in the temporary file area and is not seen with the file commands. If the content is to be kept, it is printed to the screen with -qO- and saved with | to-file <name>.
Duration	It closes when the download is complete; it is stopped with Ctrl+C.
Recording	Every run is written to the user logs.

Frequently Used Parameters

Parameter	What it does	What is written after it
-q	Hides the progress and information messages	—
-O-	Writes the content to the screen instead of to a file	—
-S	Writes the response headers of the server as well	—
-T	Determines the timeout duration	Seconds
--header	Adds a header to the request	"Header: value"
--no-check-certificate	Skips the certificate verification	—

The table summarizes frequently used parameters; the full list and behavior depend on the version of the tool on the device.

Examples

admin@TR7LBWAF01> sys-cmd wget -qO- http://10.20.0.30/version

admin@TR7LBWAF01>  

TR7 WEB-CLI · B) A health address with a self-signed certificate, with a 5 second limit

admin@TR7LBWAF01> sys-cmd wget -qO- -T 5 --no-check-certificate https://10.20.0.30:8443/health

admin@TR7LBWAF01>  

TR7 WEB-CLI · C) Together with the response headers

admin@TR7LBWAF01> sys-cmd wget -S -O- http://10.0.7.20/

admin@TR7LBWAF01>  

TR7 WEB-CLI · D) Save the content to a temporary file

admin@TR7LBWAF01> sys-cmd wget -qO- http://10.20.0.30/metrics | to-file backend-metrics.txt

admin@TR7LBWAF01>  

Things to Know

• The headers are red on the screen. Because the response headers that come with -S are written to the error output of the tool, they appear in red; this is not an error. When it is connected to a pipe, these lines do not come to the screen.
• For downloading the saved file, the link in the output of file list is used.
• For a detailed HTTP diagnosis (the method, the body, the redirect, the TLS detail) curl is used.
