Thank you for posting in Intel Communities. We sincerely apologize for the inconvenience caused. DevCloud was down from past two days. You can try the below steps to re-connect to devcloud again.

1) Download the new key from this link: https://devcloud.intel.com/oneapi/documentation/connect-with-ssh-linux-macos/

2) Move/Copy this file to ~/.ssh folder & rename it to "devcloud-access-key-xxxxx.txt"

3) Give permissions to the file/folder as below:

chmod 600 ~/.ssh/devcloud-access-key-xxxxx.txt
chmod 600 ~/.ssh/config

(Ignore this step if you're connecting through Mobaxterm. This step is required only for Cygwin.

If this resolves your issue, please accept this as a solution as it might help others with the similar issue. Thanks in advance. Please let us know if this issue still persists.

Unfortunately, While devcloud has migrated to a new SSH server, some users are facing this key issue. We are looking into this issue. We will connect with you via private message/email.

Hi,

I am also facing the issue. I completely removed all ssh configurations including the key and set everything up again with the setup script. Unfortunately the key is rejected as well:

guest@ssh.devcloud.intel.com: Permission denied (publickey).
kex_exchange_identification: Connection closed by remote host
Connection closed by UNKNOWN port 65535

I checked in the ssh config file that it is directing to ssh.devcloud.intel.com
