No that hasn’t changed. error reading private key file fqdn/ECDSAP384SHA384/41844 is short hand for error reading private key file for ‘fqdn' with algorithm ECDSAP384SHA384 and key id 41844. At this stage I suggest that you post actual config details and actual command lines rather than describing what you have done as the error will be in the details which we can’t see without them. > Regards, > > Michael > ____________________________________________________________ > Technische Universität Dresden > Fakultät Wirtschaftswissenschaften > Lehrstuhl für Entrepreneurship und Innovation > Prof. Dr. Michael Schefczyk > D-01062 Dresden > > Fon: +49-3 51-4 63-3 68 81 > Fax: +49-3 51-4 63-3 68 83 > www.gruenderlehrstuhl.de > > > > > Are you running chrooted?
