Had trouble to connect to our MySQL database, so I decided to open a ticket to the Database admins. At least they are pros and I'm sure they'll help me:

"Hey guys, I have trouble connecting to [Hostname]. I guess it's a firewalling issue would you take a look? Attached are screenshots, saying hostname not found.

Answer:
Hey Dominique, are you sure the password you used is correct? Is it yours or the sysuser pw what you sent to the server? How did you send it?

Me: (kind of confused) Hey dear admin, did you look at my error message? It says Hostname not found. What do you think how I provided any credentials?

Support: yes, I saw your screenshot and don't see any password entry. That's why I asked!

Me: Well, than... ok... go and search for another job. Yeah and consider fucking yourself. Kisses.
