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.

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
Error: Quartus Prime Shell was unsuccessful. 2 errors, 0 warnings
For more details, full Quartus compile output can be found in files quartuserr.tmp and quartus_sh_compile.log.
Error: Compiler Error, not able to generate hardware

 

 

I really need help to fix this issue. !!
