Document Snowflake's FreeBSD Package/Port

we just introduced Snowflake to the FreeBSD's ports tree:

today version v2.0.1 was ported to the ports collection, used to build official packages for FreeBSD. now we should have official packages available to install Snowflake ]=)

there are 3 different binaries shipping with its package:

snowflake
snowflake-client
snowflake-proxy

FreeBSD uses pkg as its official/main packages manager. it provides an interface for manipulating packages: registering, adding, removing and upgrading packages. after installing a package, we can be presented a message containing few notes about a particular software.

we worked out to present intuitive instructions to setup following scenarios:

  • standalone proxy;
  • client transport plugin,
  • server transport plugin.

besides Snowflake's source code and its documentations, the following material was used to build the port:

tpo/core/tor#21453 (closed)

tpo/core/tor#24203 (closed)

on top of that, the Snowflake Bridge Survival Guide was also pretty handy

by running the standalone proxy on FreeBSD, this would be an output of its log file:

there will be packages for different versions and architectures available. should anyone wants to test it right away (once the package is available):

# pkg update -f
# pkg install -U snowflake-tor
# service snowflake onestart
