So I built a new RHEL 5 system and applied all necessary updates on it. This takes it up to version 5.5, but Tripwire’s server doesn’t want to install due to the version being too high. Though I REALLY wish 3PD’s would embrace the concept of “if $ver => 5.3″…

Anyhow, they DID put a flag in to fix this little annoyance. To fix it:

./install-server-linux-amd64.bin -DIgnoreOSVersion=true

Thank gods someone thought ahead!
