how did i never know about .ssh/config?

I’m sure folks have tried to explain this to me before, but it wasn’t until today that it finally clicked – using .ssh/config will save you a world of hurt when managing various systems from a Linux host (I imagine it works on other platforms, too – but I’ve only started using it on CentOS).

Following directions I found here, I started a config file on a server I use as a jump box. In it I have an entry for my web server, and I’ll be adding other frequently-accessed servers to it as time goes on.

Thanks, nerderati, man pages … and whomever else tried to explain this to me before but I didn’t grok.
