This article explains the cause and resolution when users are unable to copy the Security Director Insights (SDI) upgrade image to the SDI server.

When attempting to copy the SDI upgrade image, the following error is observed:

Core# (server) # set system-update copy user@<remote-server-ip>:/data/insights_release_22.3-22.3-21-s32c16-Upgrade.zip.tgz

ssh: connect to host <remote-server-ip> port 22: Connection refused
SCP exited with error: 1

The upgrade image copy operation fails.

Use a Linux-based system to host the SDI upgrade image and copy it to the SDI server.

Recommended approach:

• Place the SDI upgrade image on a Linux server

• Ensure SSH (port 22) is enabled and accessible

• Retry the copy operation from the SDI CLI

Once the image is hosted on a Linux system with SSH enabled, the copy operation should complete successfully.

Note: If the issue persists, please contact JUNIPER JTAC Support for further assistance.
