Thomas gave me this input earlier, too, so I added the one liner. There was a long discussion on accessing the port a few years ago: https://lkml.org/lkml/2008/9/24/512 > > > Furthermore, this port is shared > > by other VMware services for host-side communication. > > What services would that be? Do they reserve the port? This port is used by quite a few guest-to-host communication capabilities, e.g. getting configuration, logging, etc. Currently multiple kernel modules, and one or more priviledged guest user mode app, e.g. open-vmware-tools, use this port without reservation. After some internal discussions, it was determined that no reservation is required when accessing the port in this manner.
