curl cannot authenticate with router using basic http authentication
Date: Thu, 11 Jul 2019 07:23:37 -0400
I have a script that runs in my router every so often to reboot my modem.
The script works with wget, but I would like to implement it with curl
because this script is the only reason I have wget installed.
The trouble is that while wget can authenticate with the modem, curl
cannot. Here is the output of the relevant commands:
--------------------
bruno_at_box:/opt$ wget -O /dev/null

--------------------
I tried other authentication methods (e.g., --digest) without luck, which
is not surprising (the modem reports it uses Basic http authentication).
Any ideas how to make the authentication succeed?
Thank you,
