Hi,

 

We could reproduce your issue.

 

AlekhyaV_Intel_1-1663153084755.png

 

Please find our observations below:

 

We are assuming that your devcloud config file doesn't have the below part. If you do not have, please add this to your config file(path: <mobaxterm/cygwin installed path>/.ssh/config)

 

 

# SSH Tunnel config

################################################################################################

Host *.aidevcloud

User uXXXXX

IdentityFile ~/.ssh/devcloud-access-key-XXXXX.txt

ProxyCommand ssh -T devcloud nc %h %p

LocalForward 5022 localhost:22

LocalForward 5901 localhost:5901

################################################################################################

 

 

After adding, please follow the below steps:

 

1) In first terminal,

 

ssh devcloud
qsub -I -l nodes=1:renderkit:ppn=2
/opt/TurboVNC/bin/vncserver -otp

 

You will be connected to a compute node(let's assume you have connected to s001-n145 node) and A one-time OTP will be generated.

 

2) In second terminal,

ssh s001-n145.aidevcloud

 

3) After you are connected to the compute node is the second terminal too, Open turbo VNC viewer and enter

localhost:1

Click on connect. Enter the OTP that was generated from your first terminal in the password field and click enter.

Regards,

Alekhya
