System 7 - Extension that shows internet connection status

[tommijazz91]

I’ve been wondering for a while if such an extension for system 7 exists - one that allows you to see if there’s an active connection (through Ethernet cable, WiFi, etc) by displaying on the menu bar something like a blinking icon, or two different images depending on the status. Something similar in concept to the “Eyeballs” extension. I’ve done some research through the usual websites but I didn’t find anything that matches exactly what I’m looking for. In my case, I have an SE/30 with System 7.5.5 and a CNet PDS Ethernet card and a cable that goes straight to my router, so no WiFi cards or RPi in the middle.
I also wonder, in case nothing like it exists, how difficult would it be to create one from scratch?

I remember years ago there was a hard drive activity extension that basically did the same thing.
It would show drive read / write activity through a little icon in the menu bar.
If no one chimes in with a ready-made option, I might take a stab at this... although it's probably over my head. lol

Would you want just to see an 'link' indicator for the status? I think a 'every packet blink' would be pretty intense and distracting.

There are plenty of PPP/(C)SLIP monitor control panels or extensions (you can find these on info-mac mirrors). For wired LAN connectivity there’s not really "online" or "offline", as with PPP. There’s "cable plugged in and link established", but I’ve never seen software for Mac OS for this.
When you want to know whether your computer "can do Internet" it’s quite complex - having a non-APIPA-IP-address, having a gateway, being able to reach the gateway and beyond, having a name resolver, reaching that one. And even if the computer can reach the gateway -- this can be different 5, 10, 60 seconds later -- so your Mac would need to monitor that.

I’m writing to much text to explain that this is not really something for a 8 or 16 MHz machine -- that’s quite a bit of stuff to monitor. And Mac OS and MacTCP are known to react non-cooperatively/nice to timeouts.

What exactly do you want to know from that extension? If you plug in your Mac via LAN cable to your gateway, and it’s configured correctly, your Mac should be online.
