Show all active TCP connections

To display all active TCP connections, at your command prompt:

netstat -tnlp

For example, from an AWS instance setup for serving web pages:

[root@t2-micro ssh]# netstat -tnlp

I've been a fan of Seagate since the venerable 2080. Seagate used to be the "go to" drive, but that no longer appears to be true.

A few years ago I started buying the FreeAgent GoFlex desktop external (USB 3.0) drives for backup purposes. Since it's used for backup, I need it to be reliable and why I went with Seagate (instead of Western Digital).

Both have failed and Seagate has swapped them out per warranty - no problems there. Guess what? One of the replacements has now failed and I no longer trust the other to not fail soon.

Time to start looking for a large SSD to be the replacement...
