How to enable Apache HTTP Proxy on my ESET PROTECT Virtual Appliance after initial configuration

Open terminal and according to your OS version run the following commands as root to enable Apache HTTP Proxy:



The location of apachectl and htcacheclean will vary based on your system, check it before running the script.

The parameter /var/cache/httpd/proxy determines the location of the caching folder, this location is set in /etc/httpd/conf.d/proxy.conf under CacheRoot.

Apache HTTP Proxy replaces the Mirror Tool functionality from ESET Remote Administrator 6.x. It is primarily used for caching detection engine update files and caching information from ESET LiveGrid®.

For CentOS 7

1. systemctl enable httpd

2. sudo mkdir -p /etc/systemd/system/httpd.service.requires

3. sudo ln -s /usr/lib/systemd/system/htcacheclean.service /etc/systemd/system/httpd.service.requires

4. systemctl start httpd

5. htcacheclean -d60 -t -i -p/var/cache/httpd/proxy -l10000M



You can adjust parameters for Apache HTTP Proxy cache cleaning: -d defines cleaning interval in minutes, -p specifies path as the root directory of the disk cache, -t deletes all empty directories, -i intelligently deletes cache only when there was a modification of the disk cache, -l defines total disk cache size limit.

6. iptables -A INPUT -p tcp --dport 3128 -j ACCEPT

7. ip6tables -A INPUT -p tcp --dport 3128 -j ACCEPT

8. service iptables save 

9. service ip6tables save

This will start Apache HTTP Proxy and enable port 3128 in a firewall. You will need to create policies for all ESET products / ESET PROTECT components to communicate via Apache HTTP Proxy and allow the caching of installation files / update files for ESET products. Make sure, the Apache configuration contains the ProxyMatch segment for your server host. For more information see our Knowledgebase article part II. Configure policy settings for client computers.
