# example: you start a tensorboard on pincopallo remote server and on port remoteport, you can't access it
# from your local machine but you can access it with ssh from your local machine, you can do a forward to
# make the service on pincopallo:remoteport available at 127.0.0.1:6006 from local browser
ssh gberardi@pincopallo -N -f -L localport:127.0.0.1:remote_port

alias script1='source /home/gberardi/dev/venv-name/.venv-name/bin/activate'
