Agent software updates are typically hosted and distributed by relays. However, if you already have a web server, you can provide software updates via the web server instead of a relay. To do this, you must mirror the software repository of the relay on your web server.
Although agents can download their software updates from the web server, at least one relay is still required to distribute security package updates such as anti-malware and IPS signatures (see Apply security updates).

Copy the folder structure Parent topic

Mirror the folder structure of the software repository folder on a relay-enabled agent. Methods vary by platform and network. For example, you could use rsync over SSH for a Linux computer and network that allows SSH.
On Windows, the default location for the relay-enabled agent's software repository folder is:
C:\ProgramData\Trend Micro\Deep Security Agent\relay\www\dsa\
On Linux, the default location for the Relay's software repository folder is:
/var/opt/ds_agent/relay/www/dsa/
The structure of the folder is like this:
|-- dsa
|    |-- <Platform>.<Architecture>
|         |--  <Filename>
|         |--  <Filename>
|         |--  ...
|        
|    |-- <Platform>.<Architecture>
|         |--  <Filename>
|         |--  <Filename>
|         |--  ...
For example:
|-- dsa
|    |--  CentOS_<version>.x86_64
|         |--   Feature-AM-CentOS_<version>.x86_64.dsp
|         |--   Feature-DPI-CentOS_<version>.x86_64.dsp
|         |--   Feature-FW-CentOS_<version>.x86_64.dsp
|         |--   Feature-IM-CentOS_<version>.x86_64.dsp
|         |--  ...
|        
|    |--  RedHat_EL6.x86_64
|         |--   Agent-Core-RedHat_<version>.x86_64.rpm
|         |--   Feature-AM-RedHat_<version>.x86_64.dsp
|         |--   Feature-DPI-RedHat_<version>.x86_64.dsp
|         |--   Feature-FW-RedHat_<version>.x86_64.dsp
|         |--  ...
|         |--   Plugin-Filter_2_6_32_131_0_15_el6_x86_64-RedHat_<version>.x86_64.dsp
|         |--   Plugin-Filter_2_6_32_131_12_1_el6_x86_64-RedHat_<version>.x86_64.dsp
|         |--  ...
|        
|    |-- Windows.x86_64
|         |--  Agent-Core-Windows-<version>.x86_64.msi
|         |--  Agent-Core-Windows-<version>.x86_64.msi
|         |--  Feature-AM-Windows-<version>.x86_64.dsp
|         |--  Feature-AM-Windows-<version>.x86_64.dsp
|         |--  Feature-DPI-Windows-<version>.x86_64.dsp
|         |--  Feature-DPI-Windows-<version>.x86_64.dsp
|         |--  ...
|         |--  Plugin-Filter-Windows-<version>.x86_64.dsp
|         |--  Plugin-Filter-Windows-<version>.x86_64.dsp
|         |--  ...
The example above shows only a few files and folders. Inside a complete dsa folder, there are more. If you need to save disk space or bandwidth, you do not need to mirror all of them. You are only required to mirror the files that apply to your computers' platforms.

Configure agents to use the new software repository Parent topic

When the mirror on the web server is complete, configure agents to get their software updates from your web server:

Procedure

  1. In the Workload Security console, go to Administration → System Settings → Updates.
  2. In the Software Updates section, under Alternate software update distribution server(s) to replace Deep Security Relays, enter the URLs of the mirror folders on your web servers.
  3. Click Save.
    Verify that connectivity between agents and your web server is reliable. If the connection is blocked, agents instead use the relay.
