Yesterday I just did a clean installation of Cygwin 1.7.20-1 and I have experienced exactly the same issue as you - mountd and nfsd don't start (get_myaddress: ioctl: Invalid argument in logs). Portmap starts fine.
I tried to downgrade sunrpc, but that didn't help. -- View this message in context: http://cygwin.1069669.n5.nabble.com/get-myaddress-error-with-nfsd-tp99341p99555.html Sent from the Cygwin list mailing list archive at Nabble.com. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
