I have a custom EXT that we use for a test called "web" that does this. It isn't efficient coding, but it is down and dirty and it works. (For Example, I didn't use variables in a lot of places where I should to make it portable, etc.)
It uses 4 components:
WebChk.bat - Run from BBNT client externals (script could be modified for BBWIN)WebChk.lst - Is a list of websites to be checkedWwwget.bat - Is run by WebChk.bat to test each server in WebChk.lstwget.exe - tool that does the actual testing
It produces output on the Hobbit monitor that looks like:

There is a WebChk.bat that has:

There is a wwwget.bat that has:

The WebChk.lst looks like:
www.google.com www.mydomain.com www.yahoo.com
The wget.exe was downloaded online and a version is available at http://users.ugent.be/~bpuype/wget/
If you would like, I could provide a ZIP of all components. I hadn't shared it yet because I know that it is dirty and would be hard to port since I had not used variables for the paths.

Might also want to do some HTTP checks. If your router's NAT table has problems, connection limits are hit, etc. Pretty much anything TCP based but doing an HTTP request to Google should satisfy and be easy.

Hello,
We have a request to monitor 'internet' connectivity. (When it comes from higherups...)
Just pinging up the line might not be good enough as we've had issues with our providers in the recent past. So I figured ping several well known hosts out in the cloud and if all are out, then we have no 'internet'.
I came out with the following. Seems to work, but figure I run it thru the list in case someone else has done this already...
page internet Internet Connectivity 127.0.0.1 INTERNET # conn=ip1,ip2,ip3,ip4,ip5
TIA...
