after upgrading from jessie to stretch I cannot contact my w2k3 terminalserver via rdesktop anymore:
# dpkg -l rdesktop ii rdesktop 1.8.3-2+b1 amd64 # rdesktop w2k3hostname Autoselected keyboard map de Failed to negotiate protocol, retrying with plain RDP. Speicherzugriffsfehler <-- german for segmentation fault if i downgrade only the rdesktop package back to the jessie version it works again: # dpkg -l rdesktop ii rdesktop 1.8.2-3+deb8 amd64 # rdesktop w2k3hostname Autoselected keyboard map de Failed to negotiate protocol, retrying with plain RDP. WARNING: Remote desktop does not support colour depth 24; falling back to 16 works. I tried to compile rdesktop to run a debugger but I don't manage to get the compilation running. it uses opaque struct BIGNUM directly without pointer and some x509 stuff where I absolutly do not understand how this should compile. So I am unsure how to help debugging here. cya erik
