Permissions can be fun. I grant execute to the world to the operator home directory files, just for convenience.
But I haven't really played around with extended file attributes, for example. And I wonder if anyone actually uses SELinux.
And, I'm still trying to figure out how systemd is better than init.d. It's just different. I hate things that are just different since I waste energy learning them without gaining any benefit.

Downside is you always have that caveat of one user to rule them all, you can hide him, tighten his permissions til he's almost useless but you still have to have that one shared account for all the admins to use, after all the goal is to have scripts that run root level stuff everywhere from one location, sudo helps but for a large enterprise there is no avoiding the descent into madness that is UNIX permissions itself.

Way we had everything wired at etrade, made for some nice easy scripting.

Do you own both servers? Maybe generate keys and exchange them? Sorry for the RTFM: https://man7.org/linux/man-pages/man1/ssh-keygen.1.html

But is there ever a way to use anything other than:
ssh -L xxxx:localhost:yyyy server.com or ssh -L xxxx:server.com:yyyy server.com
for example
ssh -L xxxx:anotherserver.com:yyyy server.com
for example when there are firewalls.
How would it work? Certificates only? I'd like to use a password on anotherserver.com
I know I could get what I want using a double login and chaining ports. But, it seems like a real waste if the :localhost: is just to tickle
the
bind addresses on the server.

It's not how you apply a security policy, it's that you have a security policy.
