Hi again
It's driving me crazy !!
Is there *anybody* out there that can actually launch remotely with
roslaunch ?
I just realized that it's not only pycrypto, but also paramiko that is
missing both imported by remoteprocess.py
apparently they where once indpendant ros modules. but now they are rosdep
stuff
I cant find them anywhere
None of the precanned recipes mention them
I tried all kind of things, not even the bare-bone
core-image-ros-comm/world has pycrypto.
