Domains required for Agent communication

This document explains about the domains which are required for agent communication.

Communication across remote offices is possible in two ways:

  1. Direct communication - Roaming User
  2. Through Distribution Server(DS)

Direct communication - Roaming User

Roaming Users directly contact the Patch Cloud Server. Since these users are constantly roaming, they can't be managed by a central server.

The Roaming Agents should connect to these four websites viz.

  • patch.manageengine.com
  • patchdb.manageengine.com
  • patchdatabase.manageengine.com
  • dms.zoho.com

patch.manageengine.com - This is the Server's URL. The Roaming Agent updates the patch status to the Patch Cloud Server. In order to contact the Patch Cloud Server, the Roaming Agent has to connect to patch.manageengine.com.

patchdb.manageengine.com - This website will have the latest patch information along with the download URLs. To find the missing patches during the scan process, the agent gets the latest patch details from the patch database, for which it has to connect to patchdb.manageengine.com.

patchdatabase.manageengine.com - The Roaming agent has to connect to patchdatabase.manageengine.com in order to download dependency patches from the PMP Server.

dms.zoho.com - The Roaming Agent has to connect to dms.zoho.com, to perform on-demand operations. Say a user has added a new computer to the network, and he immediately wants to scan that computer. In that case, the user should perform an on-demand operation. So, the agent should connect to dms.zoho.com. By doing so, the user will be able to scan his systems immediately.

Through Distribution Server(DS)

Distribution Server is a component which allows you to download patch binaries from the respective vendor websites and distributes it to all the computers managed by it.

The DS should connect to these websites viz.

  • patch.manageengine.com
  • patchdb.manageengine.com
  • patchdatabase.manageengine.com
  • dms.zoho.com

The Agents which belong to remote office/WAN should connect to these two websites viz.

  • patch.manageengine.com
  • dms.zoho.com

patch.manageengine.com

  • The replication of patches is done in the DS. The DS will then update the replication status to the Server, for which it has to connect to patch.manageengine.com.
  • The remote office/WAN agents will contact the Server to update the patch status. So it has to connect to patch.manageengine.com.

patchdb.manageengine.com

  • The DS gets the latest patch information from this website. It also downloads the patch binaries from the vendor's site through the download URL in this patchdb website. So it has to connect to patchdb.manageengine.com.

patchdatabase.manageengine.com

  • The DS has to connect to this website in order to download the dependency patches from the PMP Server.

dms.zoho.com

  • The DS should connect to dms.zoho.com in order to perform the operations involved in installing the agents using local AD without being interrupted.
  • The remote office/WAN agents should connect to this website to perform on-demand operations.
