My ISP Is Killing My Idle SSH Sessions. Yours Might Be Too.
We found the culprit! The connection tested after waiting slightly more than 60 minutes didn’t work, meaning they dropped the connection from their NAT table. 1 hour is too short time for them to wait – they should wait at least 2 hours and 4 minutes. I documented my findings, and sent an email to my ISP. I quickly got a response back acknowledging that this is a bug on their side, and thanking me for my research. They still haven’t fixed the problem though.
The tcp-keepalive-test gave the same result, but strangely enough the tcp-recv-test reported all connections as working. I assume this is because I pay my ISP to have a static public IPv4 mapped to my CGN address. But then why did the server’s keepalive packages get dropped in the SSH example? I speculate that my ISP drops those because they don’t refer to a valid TCP session anymore.
Actually they shouldn’t track my connections at all – they should just forward all packages, and only translate the source or destination IP. But that’s a problem for another day.

How to Setup and use Google Drive on Ubuntu 20.04 - Linux Shout
Unlike Windows on Ubuntu’s latest versions such as 20.04 LTS, we don’t need to install any extra software to connect and use Google Drive account. Everything there and we just need to login to Ubuntu using a Google account.
One of the popular public cloud services to store data is Google Drives because of free 15 GB storage.
