remote roslaunch failed to launch [closed]

edit

Hi all,

I am trying to launch nodes on a remote master machine through a launch file. My ssh keys are setup for passwordless connection. The husky.machine file to configure the launch ssh connections to the remote computer is:

<launch>
<arg name="robot_0_ip" default="$(env ROS_MASTER_IP)" />

<machine name="robot_0"
         address="$(arg robot_0_ip)"
         user="ros"
         env-loader="/home/ros/catkin_ws/husky_launcher.sh"
         ssh-port="22"
         timeout="20" />
</launch>

I stripped down my main launch file, system.launch to this:

<launch>
    #### 1: ARBITER - ROBOT COMPUTER CONFIGURATIONS ###########
    <include file="$(find husky_pursuit)/launch/game/husky.machine" />

    #### 2: ARBITER - ARENA SETUP ###########
    <include file="$(find husky_pursuit)/launch/game/arbiter.launch" /> # local

    #### 3/4: ROBOT - ROBOT LAUNCHES ###########
    <node machine="robot_0" pkg="tf" type="static_transform_publisher" name="base_link_to_laser" args="0.25 0 0.25 0 0 0 /robot_0/base_link /robot_0/laser 40" />
</launch>

It just launches one node remotely on robot_0 (the master), a static_transform_publisher. Before running this launch file, I ssh into robot_0 and run roscore. The error from running system.launch is:

... logging to /home/ajay/.ros/log/81f340de-1106-11e4-a670-801f02abdf53/roslaunch-i72ubuntu-12392.log

Based on the log file, SSH authentication was successful, but ProcessMonitor shuts down. The log file is at pastebin.com/Q2t3hEpp

Why does the remote roslaunch fail to launch?

Thanks!

EDIT: /home/ros/catkin_ws/husky_launcher.sh env-loader file:

#!/bin/bash
export ROS_WS=/home/ros/catkin_ws
source $ROS_WS/devel/setup.bash
export PATH=$ROS_ROOT/bin:$PATH
export ROS_PACKAGE_PATH=$ROS_PACKAGE_PATH:$ROS_WS
export ROS_MASTER_URI=http:// 192.168.1.125:11311
export ROS_HOSTNAME=192.168.1.125

(I added a space between http:// and 192.168.125:11311 because I can't publish links yet. It's not really there on the robot computer).
