Hi,

I am using an orin nano with the latest cuda (10.8) and I am trying to use nvidia visual profiler on Windows 11.

When I attempt to remote login, the nano auth log shows:

Unable to negotiate with 192.168.x.x port 52216: no matching host key type found. Their offer: ssh-rsa,ssh-dss [preauth]

I am not sure how to fix this. I can ssh into the orin nano from the Windows 11 machine so it appears that the keys are fine.

Any suggestions on how to fix this?

Hi, @malcolm12

Are you talking about CUDA 11.8 ?
Do you have CUDA 11.8 installed on both Windows and nano, and try to remote profile from Windows ?

Yes. Cuda 11.8. I have it installed on both Windows and the orin nano. I am trying to connect the Windows Visual Profiler to the orin nano to profile applications. I can see that the orin nano sees the connection attempt but won’t accept the ssh connection. The is from the orin nano auth log

Unable to negotiate with 192.168.x.x port 52216: no matching host key type found. Their offer: ssh-rsa,ssh-dss [preauth]

I can ssh from Windows to the orin nano without a problem.

I want to know how to connect Visual Profiler to the orin nano to overcome the above error.

Hi, @malcolm12

From the log, this still seems ssh connection issue not Visual Profiler.
