Hi,

Thank you for posting in Intel Communities.

Could you please let us know whether you are using Intel® DevCloud for oneAPI?

The error(packet_write_wait: Connection to UNKNOWN port 65535: Broken pipe) may be because the server is not kept alive due to inactivity.

To resolve open your ssh config file(~/.ssh/config). And in ssh configurations, for the below hosts

1)devcloud

2)*.aidevcloud

3)devcloud-vscode 

add the below lines to the ssh configuration

Host *

 ServerAliveInterval 300
 TCPKeepAlive no

 eg:

Host devcloud
User uXXXX
IdentityFile ~/.ssh/devcloud-access-key-uXXXX.txt
ProxyCommand ssh -T -i ~/.ssh/devcloud-access-key-uXXXX.txt guest@ssh.devcloud.intel.com
ServerAliveInterval 300
TCPKeepAlive no 

If the issue still persists, please share the following details:

1. Sample reproducer

2. Steps to reproduce the issue

3. Screenshot of the error

4. config file

Thanks.

Hi,

Please make sure that the "devcloud-access-key-uXXXX.txt" is present in the .ssh folder. 

Also run the below commands from the terminal to set the permissions:

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

Hope this helps. If the issue still persists please let us know.

Thanks.

Please check the screenshot image. I guess the devcloud-access-key-uXXXX.txt" is present in the .ssh folder. So, what is going on ??

Hi,

Could you please let us know whether you have set the correct permissions as mentioned in the previous reply?

If yes, please download the key again and try to connect.

Are you able to connect jupyter lab?

To access DevCloud using jupyter lab. Please follow the below steps:

• Go to the link: https://devcloud.intel.com/oneapi/get_started/
• At the end of the page, Under Connect with Jupyter* Lab, click on Launch JupyterLab*.

If the issue still persists, please let us know.

Thanks

Yes, I  have set the correct permissions as mentioned in the previous reply by typing the following commands. 

chmod 600 ~/.ssh/devcloud-access-key-xxxxxx.txt

chmod 600 ~/.ssh/config

But, I am not sure how to download the key again ?? 

However, 

Yes, I am able to connect using jupyter lab. But, while compiling my kernel.cl code. It gave me this error. 

Error (23035): Tcl error:
Error (23031): Evaluation of Tcl script build/entry.tcl unsuccessful

For more details, full Quartus compile output can be found in files quartuserr.tmp and quartus_sh_compile.log.
