LCM self test failed, Check your routing tables and firewall settings-CodePudding

I have ubuntu 20.04, I install drake and try run example. When I try run bazel-bin/tools/drake_visualizer & bazel-bin/examples/multibody/inclined_plane_with_body/inclined_plane_with_body I have got error:

CodePudding user response：

Something with LCM's networking configuration isn't working. For example, if there is no lo (loopback) device, or it's disabled, or configured oddly.

See https://lcm-proj.github.io/multicast_setup.html for some tips.
