Really! Learning new stuff is always good to improve yourself, even when it’s something so boring as accounting (well, this one I need to help myself believe it).
This is definitely not news for many people, but I always wondered how failban was blocking an ip.ad.dre.ss when I couldn’t find any of the banned IPs with iptables-save | grep ip.ad.dre.ss
I always left it for another time and boy did it pass long and quickly, with other things more important.
Boy, was I happy… May come in useful in the future, and in the past it was definitely very useful at times, rather than other workarounds.
Still… nice. I must thrive to make time to learn new stuff at least every weekend.
