Ignore specific topics between two computers

[Naraharirahul]

I'm trying to ignore a specific topic flowing from computer A to computer B. Is there any way of ignoring the topic apart from editing the computer B master_sync.launch file?

[atiderko]

Currently there is no way to configure master_discovery on computer A to not provide topics to master_sync on computer B. At this time you must configure master_sync.launch on computer B.

@atiderko has anything been done in this area or is the status still the same?

[atiderko]

yes, there are three parameters ~hide_nodes, ~hide_topics and ~hide_services for master_discovery. This should prevent the master_sync on another host from seeing them. However, the Node Manager can still display them.

Those parameters are not documented on http://wiki.ros.org/master_discovery_fkie?distro=melodic

And there is no http://wiki.ros.org/master_discovery_fkie?distro=noetic
