FAQ

• What license? GPLv2 (please be careful because we changed license at 10 Nov 2014)
• Do you have support for multiple IPs per containter? Yes!
• Do you have support for IPv6? Yes, we have it!
• Do you have veth support? Unfortunately, not because IP configuration for veth is not standard.
• How I can manage speed for different CT? You need change only one Perl function.

Installing

• Install required Perl module: yum install -y perl-Net-CIDR-Lite
• Put fastvps_openvz_shaper.pl into PATH folder (e.g. /usr/bin)
• Put fastvps_openvz_shaper_config to /etc/ folder (it's config with some logic)
• Change Perl subroutine in fastvps_openvz_shaper_config to your speed determining logic (by default all CT shaped to 30mbps)
• Add fastvps_openvz_shaper.pl to cron for run every 10-60 minutes.

Please be careful! We can't restrict incoming speed from external Internet to customer but we can slow down speed from hardware node to customer.
