Not sure if this exists, but I haven't seen it anywhere in here, so I'll give it a shot, eh? What software/services are installed as soon as you setup a server? Here's my list:
cPanel (dnsonly or hosting, it's a must)
. Mandatory duo push login authentication (for root only)
. Way better than the alternative, and the most intense iptables interface I've seen. Very easy to use and customizable.
nano/pico . I cut my teeth on pico. A lot of people prefer vi, but not me!
MariaDB. I've given up on MySQL any more. Maria is a drop in replacement for MySQL itself and it's just way better when dealing with larger databases and caching (which I do a ton of).
. I cut my teeth on this when I limited myself to Linux only for a time. Still use this one quite heavily. Probably the best command line ftp client out there.
The rest really depends on the server and what it's used for, but those are my absolute must have on every server. What's yours?
