Sophos Anti-Virus for Linux/Unix: Central configuration of the Remote Management System

This article describes how to apply Central Installation Directory (CID) based Remote Management System (RMS) configuration, which is useful in several circumstances:

  • Changing the ParentAddress / ParentRouterAddress after a server migration
  • Changing ParentRouterAddress to use a message relay
  • Changing the ParentAddress / ParentRouterAddress when the server IP address is behind a NAT firewall
  • It is not possible to change the ports used by RMS with this method.

The following sections are covered:

Applies to the following Sophos products and versions

Sophos Anti-Virus for Linux

Sophos Anti-Virus for Unix

The method will depend on whether endpoint installations have already been deployed or not:

  • Option 1 – Pre-Installation (mrinit.conf)

    Before installation, edit the mrinit.conf file in the root of the CID. Eg:


    If using this method, you must uninstall Sophos Anti-Virus from any endpoint that has already used the existing mrinit.conf, and re-install afterwards.

  • Option 2 – Post-Installation (mrinit.custom)

    To centrally edit RMS information on existing endpoints, you can create a mrinit.custom which will be selected in preference to mrinit.conf.

    Make a copy of mrinit.conf and edit the required values (eg. ParentAddress, ParentRouterAddress). Save the new file as mrinit.custom in the root of the CID. Eg:


    Endpoints will automatically select mrinit.custom when they next perform an update from the CID.

If you are familiar with ConfigCID.exe it should be noted that this is not required/will not work in the scenario above.;
