Charles Warwick of Tech Sstrategies gave me this info and doesn’t mind if it’s
shared. May be useful to some folk on the list! It certainly solved my question
about tserror(7).

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

if I can access me chosen server or not.
But one could certainly imagine programs that would want to know if they were

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
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
Hi Graham,
Why don’t you just check for the existence of "tsneterr: (7)”?

I just did that, but so far have only used it in the IDE. I found out two

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

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,
