I see that you are attaching your strace session to an already running
process. The setsockopt calls are done when remote-viewer connects to the
remote host, so if the connection is already done by the time you attach
your strace session, then I would not expect to get more setsockopt calls.
Can you try running remote-viewer from the start through strace?
