SSH Public Keys
Repository write access is handled by SSH tunnels that require the SSH public/private key system. == Generating your SSH key pair == On Windows, using the [[http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html PuTTy suite] is recommended. You can use PuTTyGen to generate your public and private key pair. Reading [http://the.earth.li/~sgtatham/putty/0.60/htmldoc/Chapter8.html#pubkey PuTTy documentation about key authentication] is '''strongly recommended'''. On *nix (including Mac OS X), you can just pop open a terminal and use ssh-keygen. As an alternative, less secure, method we also will generate ssh keys for you. This is accessible at: [/home/generate-keys/] == Uploading your public key == When you have your ssh keys created, upload your public key to [/users/current-profile/repository-authorization/edit/] and you should be able to use that key to have write access to projects that you are a member of. Be sure to copy the public key '''as one line without any space in the central part'''. Your public key should look like one of these depending on its type: * RSA key for SSH2 (recommended): ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAIEAvnUSCZFxE6p72IeFjYpx4R8e0uyDGARigTwtCvDdRYzD1Nbk1NXOyz1wi5WP/hEk80Qf8HoQ45D6xkyMr/FNL9yiWtlFptForphSnkZZo9L4/gk5rx9+Gg8P/u/sdx2AaKcugxn2g9s0eYotHOjl9OCIeC6rLePbxEJtQeQzsx0= optional comment * DSA key for SSH2: ssh-dss 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 optional comment == Starting a SSH agent and loading your private key == On Windows, launch Pageant (see [http://the.earth.li/~sgtatham/putty/0.60/htmldoc/Chapter9.html#pageant its documentation]) and load your private keys. *nix distributions commonly ships a SSH agent loaded on graphical login. Just try ssh-add to load your private key. If it failed, you had to launch ssh-agent and tried ssh-add again. '''This is required prior to any SSH access to the repository.''' == Testing the SSH connection == The server and username depend on the type of repository you are using: * Subversion: server svn.wowace.com, username svn, * Git: server git.wowace.com, username git, * Mercurial: server hg.wowace.com, username hg, Those will be used in any subsequent SSH connection to the repository. # Try to connect to the server using either ssh (*nix) or PuTTy (Windows). # On first connection, you should be asked to accept the server key or not. Accept it. # If everything went well, you should get the following message: Successfully connected, but no svn/git/hg command provided. You can then start to use your Subversion/Git/Mercurial client using SSH tunnels. == Troubleshooting == If anything goes wrong, please check that : * you uploaded your public key in the right format, * you have a SSH agent running with the corresponding private key loaded, * you are trying to connect to the server and the username corresponding to your repository type. Common error message: * SSH error: "no authentication method left": the authentication with the public key failed, either because you have not uploaded it correctly or you have not loaded it in your SSH agent, * SVN error: "Authorization failed": the SSH authentication succeded but you do not have the privilege to access the repository, it may be because the repository is private and you are not listed in the author list or because the project has been abandonned or deleted. Finally it sometimes happens when the authorization script bugged, you will have to contact an site administrator. When asking help on the forums or IRC, please provide the answers to the following questions: * which OS are you running (and which version) ? * which SSH software are you using (and which version) ? * the repository URL are you tring to connect to ? * what error message did you get, if any ?
