Troubleshooting services and bypassing Google's help.

Scenario 1: You're in the middle of your data center. Internal tools/tests say that $service is running correctly, but external customers says it isn't working, and firewall won't let you use an external IP without having to run 3 floors away on the other side of the building.

Solution 1: Open termux, and running telnet aaa.bbb.ccc.ddd $PORT and test

Quicker then waiting for a co-worker to get back to you on Slack.

Scenario 2: You are setting up a new VPN server and want to confirm that your outgoing connections are being routed through the correct IPs/Gateways.

Solution 2: Open termux and run tracert and see where you are being routed.

and many more....... I used to own a Nokia N900. Having a Linux CLI that works in portable device (wifi + cellular) is so damn handy. I use it atleast 2 times a week. It's a perfect diagnosing tool for OOB troubleshooting.
