Using the jPC's Ethernet Link Local Address

The jPC's Ethernet port is configured by default with a static link local IP address of 169.254.1.1. The link local address allows you to directly connect an Ethernet cable between a PC and the jPC without the need for additional hardware, such as a hub, switch, router, etc.

With just a PC (e.g. a notebook), an Ethernet cable, and with the SSH server enabled, the Ethernet Link Local address can be used to access and administer the jPC both at development time, and when deployed in the field.

Examples:

• Use ssh admin@169.254.1.1 to run commands on the jPC.
• Use scp /path/to/file admin@169.254.1.1 to copy files to the jPC.
• Use scp admin@169.254.1.1:/path/to/file . to copy files from the jPC.

Use FileZilla Client if you prefer having a GUI to transfer files to and from the jPC over this link local address.

To change the link local address, or disable it entirely, see jPC Network Configuration.
