I have 2 PCs and I'm runing Multimaster_FKIE

on PC1 when I try to publish to topic in on PC2 I got a box message said "user=robot" and "password" I think it's for SSH connection to the PC2

but when I enter the correct user and password I get a message said "start publisher for /turtle1/cmd_vel failed: bash: rosrun: command not found"

the details of the error are "Traceback (most recent call last): File "/opt/ros/indigo/lib/python2.7/dist-packages/nodemanagerfkie/progressqueue.py", line 276, in run self.target(self.args) File "/opt/ros/indigo/lib/python2.7/dist-packages/nodemanagerfkie/starthandler.py", line 560, in runNodeWithoutConfig raise StartException(''.join(['The host "', host, '" reports:\n', error])) StartException: The host "amine-pc" reports: bash: rosrun: command not found"
