Hello,

In ros fuerte i can't communicate from slave to the master! can someone help-me?

I have in the bash script for master this:

export ROS_IP=192.168.55.112
export ROS_MASTER_URI=http://192.168.55.112:11311

at the slave the same. In the slave i make rostopic list and i see all publications.

but when i run a node, in the slave pc, that should publish something, the master can't ear anything! (if run the publisher in the master and subscriber in the slave it works, the inverse not!!!!)

If i run the same node in the master everything runs ok! What could be the problem?

The slave should not export its IP to be the same as the master. It should export its own IP.
