5 years agoLooks like rdesktop has been supplanted by other tools like vinagre and freerdp. I found this example for testing RDP authentication with the latter, though I also found that the version shipped with CentOS 7 has a bug that requires an X display even when not required (as in this case).
xfreerdp --ignore-certificate --authonly -u user -p pass host
