The RNG lock error message is printed at line 201 of file random-fips.c I tested this with "localhost" but also with a remote OS X VM; both systems run 10.9.5 . Connecting to Linux hosts running the x11vnc server works fine. -- Ticket URL: <https://trac.macports.org/ticket/47769> MacPorts <https://www.macports.org/> Ports system for OS X
