Hello everyone!!!

 

I can´t conected me to devcloud by ssh, Yesterday I saw the next message about it, when I try to work with devcloud.

-------------------------------------------------------------------------

ssh devcloud
 WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!
IT 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.

Please contact your system administrator.
Add correct host key in /home/-----/.ssh/known_hosts to get rid of this message.

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.

 

Regards,

Alekhya

Hi @ruma ,


We got to know that you've approached customer care that you are facing a new issue(Permission denied (publickey)" error. Sincere apologies for the inconvenience caused.

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.


Regards,

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

Best wishes

Niklas
