|  |  | 
|  | With this error message an SSH command to Gerrit is rejected if the | 
|  | SSH authentication is not successful. | 
|  |  | 
|  | The link:http://en.wikipedia.org/wiki/Secure_Shell[SSH] protocol uses link:http://en.wikipedia.org/wiki/Public-key_cryptography[Public-key Cryptography] for authentication. | 
|  | This means for a successful SSH authentication you need your private | 
|  | SSH key and the corresponding public SSH key must be known to Gerrit. | 
|  |  | 
|  | If you are facing this problem, do the following: | 
|  |  | 
|  | . Verify that you are using the correct username for the SSH command | 
|  | and that it is typed correctly (case sensitive). You can look up | 
|  | your username in the Gerrit Web UI under 'Settings' -> 'Profile'. | 
|  | . Verify that you have uploaded your public SSH key for your Gerrit | 
|  | account. To do this go in the Gerrit Web UI to 'Settings' -> | 
|  | 'SSH Public Keys' and check that your public SSH key is there. If | 
|  | your public SSH key is not there you have to upload it. | 
|  | . Verify that you are using the correct private SSH key. To find out | 
|  | which private SSH key is used test the SSH authentication as | 
|  | described below. From the trace you should see which private SSH | 
|  | key is used. | 
|  |  | 
|  |  | 
|  | == Test SSH authentication | 
|  |  | 
|  | To test the SSH authentication you can run the following SSH command. | 
|  | This command will print out a detailed trace which is helpful to | 
|  | analyze problems with the SSH authentication: | 
|  |  | 
|  | ---- | 
|  | $ ssh -vv -p 29418 john.doe@git.example.com | 
|  | ---- | 
|  |  | 
|  | If the SSH authentication is successful you should find the following | 
|  | lines in the output: | 
|  |  | 
|  | ---- | 
|  | ... | 
|  |  | 
|  | debug1: Authentication succeeded (publickey). |
