Re: Internet checking?

Yes, trying to figure out WHY the connection failed is trickier. I think you are right that Safari pings an IP (to exclude DNS problems) and then looks at the response. A ping that has no route will report something like Destination Unreachable as opposed to timeout. On my Apple terminal, if I

Re: Internet checking?

Bob of course you’re right - in my particular case, anyway, I just want to know if I can access me chosen server or not. But one could certainly imagine programs that would want to know if they were wasting their time offering their users a broader internet access - I mean any program that

Re: Internet checking?

Hi Graham. Whether or not you are connected to the internet isn't really the issue, is it? All that means is that you have a route to the WAN port of your edge router. I mean, the real issue is finding out if you can reach a particular server on a particular port using DNS, or else a given IP

Re: Internet checking?

Rick, thanks for the reply. Well, sounds good, but as I have no idea of the range of happenings that could generate that error, I need a bit more information first! It’s odd how hard it is to find this stuff out. If it wasn’t for the nice little ‘LiveCode Error Lookup’ plug-in that’s been

Re: Internet checking?

Jacque, thanks. It seems like overkill to load up and initialise tsnet just to get a 20-byte text file. I’m really surprised there isn’t a foolproof way to find out if one’s device is connected to the internet or not. I am not good on internet functions, but don’t a huge number of apps in the

Re: Internet checking?

Here is a script I use. A lot of this stuff won't make sense because it is part of my interface with sqlYoga, but the core is a repeat loop where I open a socket to the server, then check if the socket is among the lines of the openSockets. If it is I exit the repeat loop and close the socket,
