This page is under construction pending login nodes.

Run the VS Code Code-Server on Delta in manual mode (without Open OnDemand) by following these steps:

1. In a terminal, ssh log in to Delta (see Direct Access Login Nodes).

2. Navigate to /sw/external/vscode/code-server/bin.

3. Run the following command to start the server. Replace dt-loginNN with the login node you are logged in to.

   In the following example, the user is logged in to dt-login03:

   [arnoldg@dt-login03 bin]$  ./code-server --bind-addr
   dt-login03:8899
