I am not talking about insane cryptic obfuscation, i am simply stating that advertising services by publicly naming your server what it runs is flat out n3wb stupid.
Thanks for making it so clear what services your machine provides on the public internets. I like advertising on the public internets too and sometimes I even run SSH on port 22 with root access enabled for convenience sake. Also, since I have so many servers, I make sure to run fingerd and include hints to what the root password is in my plan (everybody knows what it's like to forget a pw).
Another good thing to do, I was told that according to RFC1413, always make sure you are using identd service, it's a very helpful protocol.
I just don't get why people are so paranoid on the internet I've been a sys admin since the 90's and never once had a virus or been hacked.
I guess with everything now being a "devops" world, we should just focus entirely on convenience and forget about the old timers annoying speeches on "SPOF" and "Security/Risk Management" that block me from pushing my awesome new codes to production as quickly as possible. We use Chef and CI so I don't ever have to even think about the server itself, other that it is running Ubuntu, which is super fast and a very secure OS.
I love when new software comes out, I just grab the recipe and ship it! Even if it is geared to server farms with hundreds of machines, I probably need to use it for my 5 server cluster.
i've been playing guitar for 25 years and I still am not SRV, but i do have a few good chops. I've been coding for about 8 years, and if I compared it to guitar playing, it's like playing an arpeggio, so many ways and so easy to fuck up.. but fun as hell to play!
