host key change

[User01]

Did the host key change for DevCloud login nodes on June 22, 2022?

Hi All,

Sincere apologies for making you all wait. @User01 @risan-raja @khush @Oluwatosin @ral 

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,

I am sorry I tried repeatedly downloading and connecting. But its still showing public key rejection could you issue a new pair for me ?

I did not need to download a new access key. I am now able to connect.

Hello @AlekhyaV_Intel !!

I can connect through jupyter, but I have the same problem as my peers when I try to connect with "ssh devcloud". I have tried all the solutions I have seen in this post and none of them works in my case, I keep getting the same error.

Thanks for your help

[risan-raja]

Not resolved I tried even clearing the whole directory.

FYI, I did the above steps as well .

I am still plagued with Permission Denied Public Key,

Hello. I'm having the same problem here, trying to connect through ssh in WSL.

I redownloaded the devcloud access key, I removed the offending host SSH fingerprint, and still I receive this message:

guest@ssh.devcloud.intel.com: Permission denied (publickey).
ssh_exchange_identification: Connection closed by remote host

I've been trying to fix this issue for two days now, trying every suggestion I see in other posts, and no luck yet.

Hi 

I am having the same issue after tried all the methods mentioned in the post.

Can Intel help to resolve this issue please?

[AlekhyaV_Intel]

Hi @MDCC @JYan ,

Sincere apologies for the inconvenience caused. As DevCloud has migrated to new SSH server, some of devcloud users are still facing this issue. We are currently looking into it. We will get back to you with an update soon. We will connect with you through private email/message to get your DevCloud user ID.

Alekhya

Same problem here

[risan-raja]

This is still not resolved for me but apparently for some it has.

[risan-raja]

@AlekhyaV_Intel  Thank you for helping us out. Although the issue hasn't been fixed and it has been 2 days, would it be possible for you to give an ETA.

Thanks

Issue is still not fixed for me either
