Hi
I have this setup:
-my laptop, a MacBook pro running yosemite (called A)
-a gateway running linux (called B)
-a workstation with a CUDA-compatible card (called C).
Firewall policies prevents me from doing ssh directly to C, so usually I ssh to B and the ssh to C.
Now I’m trying to do some remote development&debugging on my laptop, so I have created a tunnel from localhost:2222 to C:22 passing through B:22 by using this command:
ssh -N -f -L 2222:C:22 user@B
now I can ssh directly to C by using ssh user@localhost -p 2222 without typing a password, since I have configured public key authentication.
The problem is that nsight cannot connect to C via this tunnel. I get an error saying
Failed to connect sshd on “127.0.0.1:2222”
org.eclipse.rse.services.clientserver.messages.SystemOperationFailedException
details are just Failed to connect sshd on “127.0.0.1:2222”
this happens when I try to create a new project. I have configured a remote connection, then I hit “Browse”, I’m asked for a password and the the error pops up.
I’ve found a similar problem here (https://devtalk.nvidia.com/default/topic/527614/?comment=3731020) but it is from more that two years ago.
Nsight is the one supplied by cuda toolkit 7.0.
Any ideas?
