An Interesting Blunder
 |
I was testing various operational aspects when it ocurred to me to check the firewall log.
Lo and behold ... all traffic from anywhere was being rejected by the web server outright.
It was as plain as the giant nose on my face.
This immediately led to an inspection of said offending firewall and voila ... I had inadvertently overwritten the web server's with that of the mail server.
The ports which were open were for the mail server.
The ports belonging to the web server were not open, and thus the traffiic was rejected at that point.
The moral of the story is likewise plain to see:
It is far better to work on complicated subsystems when one is fully awake and not in the middle of the night around 2 am like I did when I created this blunder.
Suffice it to say that the copious backups I maintain likewise came in pretty handy whereas the problem was fixed less than 1 minute after being discovered.
So while my technique may have been quite faulty my policies saw me through.
It's still embarassing for such a sophomoric error to arise such as the firewall fiasco of August twenty first two thousand eighteen !
