Followed this [TF ROS tutorial](http://wiki.ros.org/tf/Tutorials/Introduction%20to%20tf)
**Incurred error:** 
TF status is 'warn'. This reads three error messages:
1. No transform from [turtle1] to frame [map]
2. No transform from [turtle2] to frame [map]
3. No transform from [world] to frame [map]
I've tried( one at once ) these commands, viz.,
$ rosrun tf static_transform_publisher 0.0 0.0 0.0 0.0 0.0 0.0 turtle1 turtle2 100
$ rosrun tf static_transform_publisher 0.0 0.0 0 0.0 0.0 0.0 turtle1 turtle2 world
$ rosrun tf static_transform_publisher 0.0 0.0 0 0.0 0.0 0.0 turtle1 turtle2 world 100
to resolve this, while this command is running on one of the terminals $ rosrun tf static_transform_publisher 0.0 0.0 0.0 0.0 0.0 0.0 map my_frame 100
I've also followed [this ROS Q&A thread](https://answers.ros.org/question/10762/no-transform-from-base_link-to-map/), but didn't help in this case.
What am I missing in here? Please correct and clarify.
Any constructive discussions or leads will be much appreciated. Thanks in advance.

Remap client name for dynamic reconfigure
For setting up a dynamic reconfigure client I need to specify the name of the node I like to reconfigure, e.g. in Python:
self._client = dynamic_reconfigure.client.Client(some_node_name)
Now, I'd like to remap ```some_node_name``` in my roslaunch file to make it easy to use in different contexts, e.g.

Hi there, I'm very new to ROS.

roslaunch - get parameter files loaded
Hi all,
[roslaunch](http://wiki.ros.org/roslaunch/Commandline%20Tools) has some options to get the launch files included and nodes launched. However, I want to know which parameter files (yaml) would be loaded when running a launch file with a given set of arguments. Is that possible? Using the python API would also be OK for me.

rospy.ServiceProxy master port mismatch
On my dev machine I run ros master on default port `11311` via `ROSLaunchParent` as follows:
os.environ["ROS_IP"] = ""
os.environ["ROS_MASTER_URI"] = "http://:11311"
roslaunch = ROSLaunchParent('', [], is_core=True, port=11311)
roslaunch.start()
stdout states that the roslaunch server is running on port `43121` (changes randomly between starts of roslaunch):
started roslaunch server http://:43121/
The master seems to be started on port `11311`:
auto-starting new master
process[master]: started with pid [15304]
ROS_MASTER_URI=http://:11311/
I use [`docker-py`](https://docker-py.readthedocs.io/en/stable/index.html) (`dc` is a `client`, `di` is an `images` instance, `dn` is a `network`) to run a ROS node `` in a docker container which connects to the dev machines master.
dn = dc.networks.create(name='some_test', driver="bridge")
some_node = dc.containers.run(image=di[0].id, environment=["ROS_IP=", "ROS_MASTER_URI=http://:11311"], name='', network='test', command=rosrun_command, detach=True, tty=True)
`import rosnode; nodes = rosnode.get_node_names(); print(nodes)` lists `/` (and `/rosout`). `some-node` is (at least) discoverable in the network. So far so good.
If I send multiple service requests with
rc_itempick_start = rospy.ServiceProxy('//', )
rc_itempick_start()
a random port is used instead of `11311`:
core.py WARNING Unknown error initiating TCP/IP socket to :35516 (rosrpc://:35516)
(...)
error: [Errno 113] No route to host
core.py WARNING Unknown error initiating TCP/IP socket to :60739 (rosrpc://:60739)
(...)
error: [Errno 113] No route to host
(etc.)
Can someone help out in cross-checking what I missed?

can we dynamically turn off respawn attribute?
we have a node has respawn being true in the launch file, for debugging purpose, when the node dies, instead of shut down the whole stack, we would like to only turn off this attribute, like setting it to false dynamically, then use gdb to launch this node? do we have a command could help do so?

Launching roscore from python IDE
I am looking to create a Python method which will edit the bashrc to give it the proper IP addresses, source the file, and then start roscore. The work I am doing is in the PyCharm IDE.
The bashrc file looks good, but when I run roscore by using either the os.system or subprocess.popen commands and calling "/opt/ros/kinetic/bin/roscore", the roscore bringup crashes with the error:
Traceback (most recent call last):
File "/opt/ros/kinetic/bin/roscore", line 36, in
from rosmaster.master_api import NUM_WORKERS
ImportError: No module named rosmaster.master_api
I understand that protocol is to launch roscore using roslaunch from the command line, but for my purposes that won't work. Any advice as to how to successfully launch roscore (and other ROS files) from the command line using an IDE?

Can I run a bash script using roslaunch?
I read http://answers.ros.org/question/12327/is-there-a-way-to-wait-for-certain-topics-to-be-published-in-a-launchfile/ and http://answers.ros.org/question/33772/run-shell-command-from-launch-script/ questions and I am confused. I see people mention the possibility of running bash scripts via .launch files but I can't find any documentation describing how to do it. Is it even possible?
(I'm trying to delay the launch of a gpsd_client node because during startup it scans and usurps other serial ports.)

How does remap work internally?
