\section2 Configuring SSH Connections
SSH connections are established via an OpenSSH client running in master
mode, if possible. Connection sharing is enabled by default to allow
sharing multiple sessions over a single SSH connection. This way, a
connection is only established once and then re-used by subsequent run
and deploy procedures, saving connection setup overhead particularly
with embedded devices. Because connection sharing is not supported on
Windows, a new SSH connection is created for each deploy or run procedure.
To create SSH connections, you must install the \l{https://www.openssh.com/}
{OpenSSH} suite, which includes the ssh, sftp, and ssh-keygen tools on the
development PC.
To tell \QC where it can find the tools, specify the paths to the
directories where the tools are installed in \uicontrol Edit >
\uicontrol Preferences > \uicontrol Devices > \uicontrol SSH:
\image qtcreator-ssh-options.png "SSH preferences"
\list
\li Deselect the \uicontrol {Enable connection sharing} check box to
create a new SSH connection for each deploy and run procedure. This
option is grayed on Windows, where connection sharing is not
supported.
\li In the \uicontrol {Connection sharing timeout} field, specify the
timeout for reusing the SSH connection in minutes.
\li In the \uicontrol {Path to ssh executable} field, enter the path
to the directory where the OpenSSH executable is installed.
\li In the \uicontrol {Path to sftp executable} field, enter the path
to the directory where the SFTP executable is installed.
\li In the \uicontrol {Path to ssh-askpass executable} field, enter the
path to the directory where the ssh-askpass executable is installed.
Usually, you can use the default path that points to the
implementation of the tool delivered with \QC, qtc-askpass.
\li In the \uicontrol {Path to ssh-keygen executable} field, enter the
path to the directory where the ssh-keygen executable is installed.
\endlist

\section2 Generating SSH Keys
If you do not have an SSH public and private key pair, you can generate it
in \QC. The connection wizard can create the key pair for you, or you can
create it separately.
You can specify key length and the key algorithm, RSA or ECDSA.
If you only use the keys to protect connections to the emulator or
device, you can use the default values.
\list 1
\li Select \uicontrol Edit > \uicontrol Preferences > \uicontrol Devices
> \uicontrol Devices > \uicontrol {Create New}.
\image qtcreator-ssh-key-configuration.png "SSH Key Configuration dialog"
\li In the \uicontrol {Private key file} field, select the location to save
the private key.
The \uicontrol {Public key file} field displays the location to save the
corresponding public key.
\li Select \uicontrol {Generate And Save Key Pair} to generate and save the
keys at the specified locations.
