Correct.
 
Network administration is a job for pussies.

Shows what you know: that wouldn't be "network administration", it would
be "systems administration" (or systems engineering, or systems
architecture, depending).

"Network administration" would be mostly talking to routers -- something
you've never done either, apparently.

I speak, and advocate, only for high performance computing on GNU/Linux
workstations.

I don't think you know what a "workstation" is, if you think it wouldn't
have any services being offered to the network.  My workstation, for
example, runs Samba with the "fruit" plugin for time machine backups from
Mrs. vallor's Mac Studio.

That doesn't mean the services are available to the whole Internet, of
course, because most people have a CPE that firewalls all that, as well as
offers NAT.  I do have an application that I occasionally run that needs
a UDP port on the Net, and that is handled with uPnP.

TL;DR:  If you intend to have any qualifications for administering
Linux systems, two tools for your toolbox are ip(8) and ss(8).
