Recently I came across a few HP G8 servers at work that still had older iLO 4 firmware versions installed. This presented a problem because in August of 2017 there was a vulnerability patched which would allow a remote attacker to create their own Admin level user and enter the system.
IFTTT stands for "If This Then That" and currently allows me to power on and off my Linux servers. Below i'll lay out exactly how I accomplished this.
Linux server with out-of-band (ilo, idrac)
Always-on Linux server (I'm using an odroid c2)
