![]() ![]() So I go to dev machine, seems ok no warning on login, X11 opens up when I run something that requires window server, but once I get to git pull it goes off with: That we can get rid off by pointing to right xauth location since it has changed in new version of macOS and no one told us specifically… well maybe they did, but sure as hell nobody reads changelogs that are couple pages long… So this line will save the day here: XAuthLocation /usr/ X11 / bin / xauthĪnd that should be it for the setup. Warning: No xauth data using fake authentication data for X11 forwarding. This first one can be easily solved by adding a line in config: ForwardX11Trusted yes Warning: untrusted X11 forwarding setup failed: xauth key data not generated So by now X11 forwarding should be working… well it’s not, you will probably meet one of these: so lets add X11 forwarding there… Host * ForwardX11 yes UseKeychain yes AddKeysToAgent yes IdentityFile ~ /.ssh/i d_rsaĪnd of course this will not work out for you if you do not have X11 installed on your mac, now is XQuartz app that you can just google away, because you need to use most up to date one anyway. How I am used to work is that from the remote server I open apps that require window server (X11) to be running to display output from the dev machine that I am using. And the piece of code is here: Host * UseKeychain yes AddKeysToAgent yes IdentityFile ~ /.ssh/i d_rsaĪs simple as the config can be right? Well not quiet yet. Just for someone that does not know, the old behaviour means that you mac keeps your identitties between restarts. So here I found out that I can mimic the old behaviour by only adding couple things in config. ![]() Here the rules go: server name and under it indented by tab all the options/properties or how you call them. So starting here, we need to create file ~/.ssh/config if you got none, that is the place for the configuration. Mac simply forgets your identities.īefore it was enough to get him to use Keychain Access by running ssh -K /path/to/key but that does not work anymore and according to what I read through SO it seems it desired behaviour by apple… well not by us right ? Trouble started once I punched in ssh SERVERNAME to log into our company development machine…įirst I started off with new annoying problem that happens above macOS 10.12. Fresh install and so, I thought it is going to be easier… As far as brew that I use on MacOS goes and libraries I was missing from the backup all went well… As the story goes I got my stuff back, but somehow iTerm got a bit off so I started over with it. You cannot fathom what I just survived with setting up some stuff after “tiny loss of data” and recovery from timemachine backup. You can also manually paste in the key rather than using id_rsa.As a shout in the dark I have to write this…. Assuming your private key is stored in id_rsa, you can run: ssh-add ~/.ssh/id_rsa You can use the utility ssh-add to add keys to your local agent. All you’ll have to do is make sure your keys are added to ssh-agent and configure ssh to use forwarding. On Mac and Linux, SSH agent forwarding is built into ssh, and the ssh-agent process is launched automatically. RELATED: How to Lock Down Your SSH Server How to Enable SSH Agent Forwarding Github doesn’t care that your local machine answered the question, it just sees that it’s been answered, and lets you connect. Your local machine answers the question and sends the response (which does not include your private key) to the server, which forwards it back to Github. ![]() Usually the server would consult its own id_rsa files to answer, but instead it will forward the question to your local machine. It works like this: you ask your remote server to pull some code from Github, and Github says “who are you?” to the server. ![]()
