Since a little while Debian 5.0 Lenny was released. Like ever mostly everything works perfekt – excepting the installation of VMware Tools in an VMware Workstation or ESX enviroment.
The problem is simple: the VMware Tools from ESX 3.5 and/or Workstation 6 are too old, they need an get_info method for being compiled. But this method was remove in Kernel 2.6.26!
