Extracting the current ISP assigned IP address from a Linksys BEFSR41 V.2 Etherfast Cable/DSL Router.

The Linksys is setup and monitor using a browser. But a login with just a password and no username is required by the linksys before access to even the read only status page.

With the lynx text browser of linux I use lynx -dump 192.168.1.1 page and extract the IP address. But lynx does not have a way of passing only a password.

I looked into how I could use netscape and found with netscape --help
-remote <remote-command> to execute a command in an already-running Netscape process. For more info, see
home.netscape.com
From the x-remote page I cam up with this command sequence.

rm test_file.txt ; netscape -remote 'openURL(http://192.168.1.1/Status.htm)' ; netscape -remote 'saveAs(test_file.txt ,text)' ; grep IP test_file.txt | tail -1 | awk '{print $3}'

The rm removes file as a query about overwriting comes up otherwise.
netscape -remote 'openURL(http://192.168.1.1/Status.htm)' open the page.
netscape -remote 'saveAs(test_file.txt ,text)' save the page
grep IP test_file.txt extract lines with IP
tail -1 filter the last line with IP
awk '{print $3}' print the third item of the line that is the IP address.
