Network related bash question

Post by Logansfury »

Hello everyone,

I want to see if I can manage to make a conky widget that displays the status of the computers in my network.

I know all my computers device names, local IP addresses, and mac addys. I wanted to make a little graphic widget that lists all the comps by name and presents either a red or green indicator to show if particular comp is online and available. How should I best go about this? Would setting up a script to send like a single ping every 1-5 mins to each comp on the network be realistic? What script could react to the returning data?

I honestly don't know if this is a basic or complicated ask >.<

Thanks for reading,

Logan

I personally use the graphbar for this. So i can see on/offline for over 10 minutes and also ping in milliseconds.
Bar changes color if ping is low (green), average (grey), high (orange) and offline (red). You can even use domain names.

HOLY CRAP!!

I just got back from walking the dog, sorry for the delay in response.

This is EXACTLY what I was wanting, a display of my home intranet comps with thier 192 local addys and indicators of on and offline.

I had actually just earlier finished a background image to put green or red indicators by:

Im grabbing all the scripts you have provided here to see how they look on my system

I may put some stuff on the 2nd monitor!

I have copied these two files, I have edited in my own intranet addys, separated by spaces, and I have chmod +x on the .sh file. When I fire up the .conky all I see is the word network, none of my IPs are listed.

What must I do to activate this?

But you need to edit the /etc/host file for this one. Add all hostnames and ip's.

My host file looks like this:
