From my OpenBSD firewall I use PERL to reboot my cable modem around 3:00 am. I do this daily to obtain a new IP from my ISP otherwise I end up with a static IP for weeks. The procedure I use:

Send modem GET command with username and password to login. (unable to send a POST only GET)
After login send GET command to get webpage (HTML) that contains the sessionKey.
Note: I parse this page using PERL to get the sessionKey. (token value)
Send POST command to modem with sessionKey and reboot command to reboot modem. (sessionKey is required)

PERL is installed in the base install of OpenBSD. So I use this along with PERL module HTTP::Tiny to achieve the above. I was using PERL module HTML::TokeParser::Simple to parse the webpage (HTML) from the GET command I send to obtain the sessionKey (token value) that I send in my POST command.

The reason I asked the question reference parsing the HTML using PERL is that by default HTML::TokeParser::Simple isn't installed on OpenBSD by default and I had to install that as a package. I was just trying to find another means.
