Working With PuTTY

Index of All Documentation » Wing Pro Reference Manual » Remote Development » SSH Setup Details »


Use the following instructions to set up SSH access from Windows using Putty.

If you don't already have it, download and install the complete suite of tools provided by PuTTY. You will need putty.exe, plink.exe, pscp.exe, and puttygen.exe. We recommend using the MSI installer, so you have all the necessary tools placed in a location where Wing can find them.

Generating an SSH Key Pair

If you don't already have an SSH key set up, you will need to generate one by running puttygen.exe, pressing the Generate button, providing the requested random input by moving your mouse over the blank area, entering and confirming a passphrase, and then saving both the public and private key files. The private key file is typically named id_rsa.ppk and the public key file is id_rsa.pub. Then paste the contents of the area labeled Public key for pasting into OpenSSH authorized_keys file into a file that you will transfer to the remote host to add it to ~/.ssh/authorized_keys. You can right-click to select all and then copy from the puttygen.exe window.

Moving the SSH Public Key to the Remote Host

Assuming you saved the OpenSSH formatted public key to a file named openssh.pub you can install it on the remote host as follows:

plink username@remotehost "mkdir .ssh; chmod 700 .ssh"
plink username@remotehost "sed -i -e '$a\' .ssh/authorized_keys"
pscp openssh.pub username@remotehost:.ssh/pub.tmp
plink username@remotehost "cat .ssh/pub.tmp >> .ssh/authorized_keys; rm .ssh/pub.tmp"

The first line above is only needed if you do not already have the directory ~./ssh on the remote system. The second line is only needed if you already have ~.ssh/authorized_keys on the remote system, to ensure that it ends in a newline so your added key is on its own line. The third and fourth lines transfer the OpenSSH formatted public key to the remote host and add it as a key that is authorized to log in without entering a password.

Loading the SSH Private Key into the User Agent

Finally, run pageant.exe, right click on the small icon that appears in the lower right of your screen, select Add Key, and select your id_rsa.ppk private key file.

Note that you may need to restart pageant and load your key into it each time you restart Windows or log out and back in.

Now you should be able to connect to the remote host without having to enter a password as follows:

plink username@remotehost

Using a Non-Default SSH Port

If your remote server is running SSH on a non-default port, then you will also need to edit your SSH configuration on the host where the IDE is running to set that port. This is done by running putty, entering a host name or ip address and the port number to use, and saving that host name as a saved session (all on the initial Session tab). Once this is done, any connection to that host name, also if made from the command line or Wing, will use the configured port.
