as you can see, this conky checks if it is connected to eth0 (Wired) and if not it is not then it checks wlan0 (WiFi) and if not than it shows the state of the lo interface (we can replace it with the message "You are not connected to the internetz")
My Problem is the following line/information/parameter etc.
${color1}External IP:$alignr${color2}${execi 300 wget www.whatismyip.com/automation/n09230945.asp -O - -q}
${alignc}${color1}NETWORK ${if_up wmaster0}${if_existing /proc/net/route eth0}(Wired)

${color1}External IP:$alignr${color2}${execi 300 wget www.whatismyip.com/automation/n09230945.asp -O - -q}
${else}(Offline)
${color2}${font zekton:pixelsize=36}${alignc}Disconnected${endif}
instead of asking "if connected to the internetz" it asks ${if_up wmaster0} means "is the wireless switch is on" but I find it useless because I usually turning it off and no matter if the Wired Interface is "online", as long as the wireless switch is off the message will be "Disconnected"
and... the problem with this line:
${color1}External IP:$alignr${color2}${execi 300 wget www.whatismyip.com/automation/n09230945.asp -O - -q}
is that it's relevant to both wlan0 and eth0 interfaces and I find in inefficient to copy the exact same line in thhe same script (actually, it is more than one line)
How to ask conky "if connected to the internetz"?

Answer 1

This is what I use in my conkyrc to tell whether I am connected, and what type of connection I have.
I know many of the lines are repeated inside the if statements, and I don't know if there is another way. There is no way to call a function in conky that I know of (I could be wrong though)
NOTE: I removed all my $color and $offset entries to make this more easily readable.
