If you are using cPanel you will need to use the account’s cPanel username and web address for the keys to work correctly. To begin the process you will need to generate keys. Ssh-keygen -t rsa.The error message: WARNING: POSSIBLE DNS SPOOFING DETECTED! RSA host key for gitlab.home has changed,SSH Keygen in Mac OS X. When you execute this command, the ssh-keygen utility prompts you to indicate where to store the key.Open up the Terminal by going to Applications > Utilities > Terminal In the terminal, use the following command to start the key generation. Ssh-keygen -t rsa.This starts the key generation process.This could either mean thatDNS SPOOFING is happening or the IP address for the hostAnd its host key have changed at the same time.Offending key for IP in WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!Someone could be eavesdropping on you right now (man-in-the-middle attack)!It is also possible that a host key has just been changed.The fingerprint for the RSA key sent by the remote host isSHA256:cTU/0LDw0ywVquhsmkVuOYJNXsN1Ivmdnz/ozej4WOo.Please contact your system administrator.Add correct host key in /Users/john/.ssh/known_hosts to get rid of this message.Offending RSA key in /Users/john/.ssh/known_hosts:15RSA host key for gitlab.home has changed and you have requested strict checking.Host key verification failed. Mac OS X has an SSH client built in.Has a different value. The most versatile way to.
![]() ![]() The host public key is sent to each user and the private key is only stored on the host. That is because each user has their own known hosts file. Even if the users are using the same computer as you. Other users that have never logged on to the server before will not be refused to log on. Os Ssh- Mac Known_Hosts DefaultOn a Unix system like MacOS, the mac known_hosts default path is /Users/john/.ssh/known_hosts. A standard text editor can be used. Remove RSA key manuallyYou can also remove the key manually without using the keygen remove command. Then it will ask if I want to store the key permanently. Since I have used the IP address and the hostname before it would be best to remove both.Next time I try to connect to that server it will say the RSA key fingerprint can’t be found. To remove the ssh key from our mac we will use the keygen with the following command line:In my case this will output the following response:Original contents retained as /Users/john/.ssh/known_hosts.oldI can also use the hostname to remove the key. ![]() It does not store any personal data.
