Intel VTune Profiler error for Mac: Cannot communicate with the target

Question

I'm using Intel VTune on my personal MAC, to profile a remote application on a Linux server. I followed the instructions on https://software.intel.com/content/www/us/en/develop/documentation/get-started-with-vtune/top/macos.html.

When configuring analysis, in the WHERE pane, I selected Remote Linux (SSH) and specified the SSH destination with username@hostname. But I got Cannot communicate with the target username@hostname.

I have configured the password-less connection, which means I can directly connect to the target via the command ssh username@hostname without a password. I have no idea why it said I cannot connect to the remote target. Any suggestions? Thanks.

Edit: I still have not solved this issue... I notice the second line "VTune Profiler installation directory on the remote system". Must VTune be installed on the remote server? Could this be the problem?

Answer 1

I have tried this without any problem, so I suggest to see possible issues section and follow them, it may help,

https://software.intel.com/content/www/us/en/develop/documentation/vtune-help/top/set-up-analysis-target/linux-targets/remote-linux-target-setup/configuring-ssh-access-for-remote-collection.html

I usually use this command to set the passwordless ssh command, and it works for me:

cat ~/.ssh/id_rsa.pub | ssh remote_username@server_ip_address "mkdir -p ~/.ssh && chmod 700 ~/.ssh && cat >> ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys"
