wanted: CLI tool to determine if Internet access yes/no

[brotherS]

Hi,

I really could use such a small .exe, that maybe would just ping www.google.com and return the state so that I could use it in AutoHotkey. You know of anything?

I'm not sure, but i think this has already been done (not sure, but i think by me). Please check on coding snacks.

I did a forum search (and just now another one) but didn't find anything...  Do you remember any key words?

Ok, now i remember i couldn't quite do this, but got some solutions (i think).
(btw: if you just want to know if the internet access is on or off on ahk, you could use the URLDownloadToFile command, and check what was it's errorlevel. In case the page couldn't be downloaded, the errorlevel will be different from 0.)

Here's the other thread i mentioned: http://www.donationcoder.com/forum/index.php?topic=2999.0

Right, just trying to download http://www.google.com/index.html should work!

What about the ping command that comes with Windows?

Usage: ping [-t] [-a] [-n count] [-l size] [-f] [-i TTL] [-v TOS]
            [-r count] [-s count] [[-j host-list] | [-k host-list]]
            [-w timeout] target_name

Options:
    -t             Ping the specified host until stopped.
                   To see statistics and continue - type Control-Break;
                   To stop - type Control-C.
    -a             Resolve addresses to hostnames.
    -n count       Number of echo requests to send.
    -l size        Send buffer size.
    -f             Set Don't Fragment flag in packet.
    -i TTL         Time To Live.
    -v TOS         Type Of Service.
    -r count       Record route for count hops.
    -s count       Timestamp for count hops.
    -j host-list   Loose source route along host-list.
    -k host-list   Strict source route along host-list.
    -w timeout     Timeout in milliseconds to wait for each reply.

Then I'd need to store the output and check it. I think it's just easier to use jgpaiva's idea.

Aha! After reading the linked thread I see better what you're after. I've used Pingometer with good success (it's mentioned in that thread). There's a related util called WWIP (Watch WAN IP) if you have a router. It'll basically pull an HTML page from it and look for a string that you specify. Great concept to stay current on a dynamic IP address without having to contact an external server, but I realize that's not exactly what you're looking for.
