Everything was fine until I tried downloading a zip file from server but stopped as it was taking a long time.

Now, when I try to connect to devcloud I get the message mentioned in the screenshot below.

Hi,


Thank you for posting in Intel Communities. Please answer our below questions.


1) Could you please let us know whether you're connected to VPN? If yes, please try ssh devcloud.proxy and see if you're able to connect?


2) Are you able to access Jupyter Lab?


We have provided below workarounds. Please try them and let us know if the issue still persists.

1) We have a known_hosts file in ~/.ssh folder. Can you remove that file & try reconnecting to DevCloud once again.


2) Please check if you've given the right path to the access key in your config file.


3) Please follow the Manual configuration in this document(https://devcloud.intel.com/oneapi/documentation/connect-with-ssh-windows-cygwin/)


If this resolves your issue, make sure to accept this as a solution. This helps others with similar issue.


Regards,

Alekhya

Hi Alekhya ,

Thank you for helping me out.

 

1) I'm not connected to a VPN but there is a college proxy I must log into first. No , ssh devcloud.proxy did not fix my issue.

2) I am able to access terminal ssh using my mobile data but still cannot access the Jupyter Lab.

3) I think I'll have to add proxy related info as suggested by the manual configuration guide.

    This is the link for the login - http://192.168.254.1:8090/httpclient.html .

    I'm not sure what the proxy name should be according to the guide. I've tried  92.168.254.1:8090 but it doesn't work.

 

 user_id : u150982

 

Thank you

Hi,


Please find out your college proxy name and add in your config file as follows:


Host devcloud-via-proxy

User guest

Hostname ssh.devcloud.intel.com

IdentityFile ~/.ssh/devcloud-access-key-<user>.txt

LocalForward 4022 c009:22

ProxyCommand nc -x <proxy_name>:<port> %h %p


If this resolves your issue, make sure to accept this as a solution. This resolves others with similar issue. Thank you!

Hello Team,

 

 

I have connected to devcloud using vscode. But i am unable to see jupyter lab at there. Do I need to manually launch it?. Along with it I am not able to see kernels (like OneAPI, Tensorflow, Pytorch ).

 

Please help
