Anyone have any ideas for only loading it on the first new login session? How to configure ssh to automatically add key to ssh-agent if user provided the passphrase? In other words, the keys are not added to the agent until you actually use them. The problem was that putty had not accepted the remote host key. Okay, thats what ssh-agent is for. Instead of updating the symlinks, uninstall the other installation which is wherever those symlinks pointed to. The key will be in the agent whenever you need them afterwards though.
If Pageant is already running, invoking it again with the options below causes actions to be performed with the existing instance, not a new one. Really need my SourceTree but can't fix it somehow. A dirty hack, but it works. Thus we strongly recommend that only users with command-line experience use this feature. The major benefit to this is that you never have to enter a password for the keys after you login through gdm, or whatever your loging in with even if the keys have a password.
You can finally verify that the key is loaded properly by running ssh-add -l. Not only that, but you can exploit agent forwarding to jump from one host to another seamlessly. So you have read this much of the article, and still we have not solved the problem of having to type your password every freaking time, have we? For example, anyone monitoring your connection would not be able to intercept the password because it was never actually sent. This guide will walk you through setting this up. Looks like I should stick to github for windows for now. Try now to login into the remote server.
And again, as the name suggest, you should never ever disclose your private key. Luckily there are a number of options. Before you can use the key you imported, you must authorize for access. If you click the Pageant icon with the right mouse button, you will see a menu. But at the end of that time, your key is gone.
By doing this passphrases must be re-entered on login as above, but cron jobs will still have access to the unencrypted keys after the user logs out. I already had this stored in the keychain; it was just failing to load it on any new terminal session. Seahorse won't prompt you if everything went okay. This will create two files: a public key normally. .
By design, the agent never ever discloses your private key, it never ever hands it over to a remote ssh or similar. Then, you place the public key on any remote server you wish to access e. This is usually used in larger networks, but of course if you have interest in this it might be worth looking into. Sure, you can verify the fingerprint of every host you connect to, and disable authentication without challenge and response in your ssh config. This saves you from having to copy and paste the key onto that remote server if you want to then hop from that remote server to another server using the same keys. Ssh will automatically use the keys in memory.
The question I than have is, where is it going instead because the passphrase is still somehow magically stored given that some of the above solutions work. Does anyone have a clue how to do this? It also allows to use multiple accounts on sites like GitHub. So if Pageant is holding your private keys for a long period of time, it's possible that decrypted private key data may be written to the system swap file, and an attacker who gained access to your hard disk later on might be able to recover that data. Load Keys when necessary As I mention in introduction, I do not need to load the keys every time I log in to the server. If you find an existing key you want to use, skip to the topic that describes how to. If a keylogger was running, your password would be lost. Each new login also spawns a distinct ssh-agent instance which remains running with the added keys in memory even after logout, unless explicitly killed.
Edit: looks like 's answer directly below is the one. You can also add one from a remote system by using agent forwarding; see for details. If your system global default shell is bash or sh, this will be true. Anyway, I finally got it to work, and here are my findings. If this is the case for you, the above example will not be working. Have a question about this project? But here is the beauty of the agent: Your private key never leaves your local computer. Note that you could even publish your public key online: there is no known way to go from a public key to your private key and to get access to any of your systems.
