This technote explains the UDP and TCP ports used by netOctopus.

Problem:

For security reasons, network administrators may restrict access from outside the network by blocking certain TCP ports. They may configure a router to filter access to different ports using a firewall. This may prevent the netOctopus Administrator from contacting Agents that are located behind the firewall.

Situation:

The netOctopus Agent listens for contact by the netOctopus Administrator on UDP port 1917. The Administrator uses a dynamic outgoing port, and does not use any specific port when searching for the Agent. Once the Administrator has contacted the Agent, the Agent listens for commands from the Administrator on TCP port 1917. The Administrator does not use any specific port when communicating with the Agent.

If a "Notification Admin" is set for a netOctopus Agent, the netOctopus Administrator listens on TCP port 1921. The Agent sends the notification to TCP port 1921 of the Admin machine. The Agent does not use any specific port when sending the notification.

In version 5.1, the Software Delivery System (SDS) was introduced. This new feature was a new and improved way of managing software deployments. The port that the Administrator and Agent use to communicate with the DCS Server is TCP 3814.

Solution:

The network manager will need to re-configure the firewall permissions to permit TCP and UDP port assignments.

Summary:

For networks where Agents may be located behind a firewall, this technote explains the UDP and TCP ports used by netOctopus.
