Hi,
It looks like VisualGDB is having trouble configuring the remote system to accept your public key.
Normally VisualGDB would open a new session, run the ‘pwd’ command immediately to find out the home directory, append “/.ssh” to it and run the following command:
test -d <SSH directory> || mkdir -m 700 <SSH directory>
If the command fails, VisualGDB would display that it cannot access the SSH directory.
You can work around this by simply unchecking the “setup private key-based authentication” checkbox in the SSH setup window or by double-checking the target directory structure and ensuring that the account you are using with SSH has the <home>/.ssh directory.
