How to do remote debugging with Nsight 5.5 on Linux?

Question

Disclaimer: I know that this question has been asked numerous times, but before Nsight 5.5 the answer simply was "You can't."

I'm trying to debug a CUDA program with Nsight 5.5 on Ubuntu. The remote machine is also an Ubuntu with CUDA Toolkit 5.5.

I setup debugging in NSight using the "Debug an application on a remote system". Whenever I try to run the application I get a "Could not start gdbserver on the remote host" error.

This is what I get on the console:

Last login: Thu Aug  1 16:09:26 2013 from host.whatever.edu
echo $PWD'>'
 :2345 /tmp/nsight-debug/flow;exit
someuser@remotehost:~$ echo $PWD'>'
/home/someuser>
someuser@remotehost:~$  :2345 /tmp/nsight-debug/flow;exit
:2345: command not found
logout

Both gdbserver and cuda-gdbserver are installed on both machines.

If I ssh to the remote host, I can run /tmp/nsight-debug/flow manually.

What might be the problem here? Is there anything missing from the setup?

This looks like a bug in Nsight, we will take a look into this matter.

Please make sure that you have remote toolkit configured for your connection.

1. From the main menu, select Run -> Debug Configurations...
2. In the left-hand tree, select you debug configuration under C/C++ Remote Application
3. Make sure that Remote toolkit combo has proper toolkit selected. If you don't have any toolkit configured, click Manage... and setup the toolkit.

Usually you will only have to setup the toolkit once per your connection - e.g. you will not have to setup it if you want to debug another application on the same remote system.
