Openwall GNU/*/Linux (or Owl for short) is a small security-enhanced Linux distribution for servers, appliances, and virtual appliances. Owl can be used as a base for installing whatever software is generally available for GNU/*/Linux systems. It offers some compatibility for software packages found in or developed for other major Linux distributions, such as Red Hat Linux.
Unlike most other "Linux distributions", Owl includes a complete build environment capable to re-build the entire system from source with one simple command ("make buildworld").
Owl combines several approaches to reduce the number and/or impact of flaws in its software components and impact of flaws in third-party software that one might install on the system.
Generally any software that will run on a Linux dedicated server will run in an OpenVZ based Openwall Linux (Owl) VPS environment.
Below are some examples of common software our customers are running in their VPSs:
Every Openwall Linux (Owl) VPS is provisioned with a static IPv6 address in addition to a static IPv4 address. This allows all IPv6 compatible applications and services running in the VPS to be accessible to clients on native (or tunneled) IPv6 networks.
With IPv4 address space depleting fast, be ahead of the transition to IPv6.Learn More ››
Dahdi (Digium/Asterisk Hardware Device Interface) timing can optionally be enabled for any Openwall Linux (Owl) VPS. This facilitates supporting certain functionality within the Asterisk PBX software, including conferencing. Several FAQ articles are provided in our Knowledgebase outlining the compilation procedure if building Asterisk from source.
Other PBX software can be installed in a Openwall Linux (Owl) VPS as well, including:
or software to provide GUI-based configuration, billing, or predictive dialer capabilities to Asterisk:
