connect to cluster - key not accessible

Question

Hello,
I have created a cluster following this workshop ([https://catalog.us-east-1.prod.workshops.aws/workshops/21c996a7-8ec9-42a5-9fd6-00949d151bc2/en-US/hpccluster/hpc-connectpcluster]) but unfortunately I can't connect to it. Here the error message:

```
Warning: Identity file XXX.pem not accessible: No such file or directory. Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
```

Answer

Hello,

From the error message, it looks like either your `pluster ssh` or `pcluster dcv-connect` command is unable to find the `.pem` identity file that you have created as part of the [Create a SSH key](https://catalog.us-east-1.prod.workshops.aws/workshops/21c996a7-8ec9-42a5-9fd6-00949d151bc2/en-US/hpccluster/hpc-ssh) section.

If the `.pem` file is in a different location, you can provide the full path of the `.pem` with the `-i` flag as shown below.

```
pcluster ssh --cluster-name cfd -i /path/to/KEY_NAME.pem
```

(OR)

```
pcluster dcv-connect --cluster-name cfd --key-path /path/to/KEY_NAME.pem --show-url
```

If you are still facing issues  after making sure that the file is present, you can open a issue on [aws/aws-parallelcluster](https://github.com/aws/aws-parallelcluster) github project with detailed steps to reproduce or open a [support case](https://docs.aws.amazon.com/awssupport/latest/user/case-management.html#creating-a-support-case) for further investigation.
