As it seems Tripwire is preparing a new toolkit. Opscheck is the first of more to come that has been released.
Tripwire created a new website / community called vWire. They moved Configcheck over to vWire and added Opscheck to the list. Where Configcheck identifies possible security vulnerabilities and Opscheck checks for VMware VMotion support by rapidly analyzing ESX 3.0, 3.5, and ESXi hypervisors.
The next thing to expect from Tripwire, euuhm vWire, euuuh… vWire Solution. You can sign up for the announcement at the vWire website.
