LTTng 2.7 is not officially supported by the opensource community anymore. Please upgrade if possible.

Did you start a lttng-relayd process on the 192.168.0.1 host? How was it started?

Was this done on the same machine where you run "lttng create" or on the 192.168.0.1 host?

5151 is not the default port for lttng-relayd. Unless you specified custom port at lttng-relayd start, the default port are 5342:5343:5344.
See the lttng-relayd man page for more information.
