roscore on multimachine issue
Hello,
Until yesterday my multi machines works well. I have two computers, one master and one slave. Today, I tried to use chrony
for use the same clock in the both computer. I did the tests in the master machine. Since then the slave can not communicate to the master which is run with roscore
but in the other side, if the roscore
is run in the "slave" the "master" can communicate to it.
I get this error in the slave machine when I try to run roscore
:
WARNING: ROS_MASTER_URI host is not set to this machine
Someone has any idea what happens?
Thanks, Aviad

So, the problem was relevant to the command lines above really.
I just remove the firewalld
pkg and it is working now.

It would probably be a good idea to show values of
ROS_MASTER_URI
,ROS_IP
,ROS_HOSTNAME
and the hostnames and IP addresses for all involved hosts.Asked by gvdhoorn on 2019-11-20 07:13:46 UTC
