From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I suggest you don't sync SSH keys. That's just increasing the blast radius of any one of those machines being compromised.
Exactly this. Don't move private keys between machines. Generate them where you need them, it's not like they cost anything
I mean, you want to copy the public keys that represents your machines, right?
Fair point, but I would equate that with syncing the authorized_keys file rather than thinking about how to sync the keys.
Right. Use some kind of centralized authentication like freeipa.
For bash aliases, I just pull down a .bashrc from github gists.
OP should just generate a unique SSH key per device (+ user).
Agreed. I’ve probably got 100 keys registered with GitHub and 98 of them the private key is long destroyed due to OS reinstalls or whatnot. Format machine, new key. New machine, new key.
FYI: You can remove the old keys from GitHub.
I like to save them for a rainy day when I need an OCD fix.
I d rather have 2 to 3 (for critical, mid, and test systems) ssh keys that are regularly rotated than 1 key per machine. I m not gonna balance 50 ssh keys; neither enter my password every time i jump hosts.
Is the url is easy to rember?
