rdesktop is still missing as of openSUSE-Leap-15.0-DVD-x86_64-Build224.1. My understanding is this is a release candidate. Workaround is to download the rpm from here and install: https://software.opensuse.org/package/rdesktop zypper in ./rdesktop-1.8.3-7.1.x86_64.rpm This package is available in the Leap 42.3 and Tumbleweed repositories.
