I’m using a development server which I currently only have IPv6 connectivity to, and I’m working on a rails application.

I tried to use bundle exec rails s -e development -p 3003 -d to start a server, but it seems it only binds to IPv4:

tcp        0      0 0.0.0.0:3003                0.0.0.0:*                   LISTEN      27165/ruby

thus I can’t connect to it. What’s my best option to proceed? I’m not really very familiar with rails just trying to fix a few issues on an existing application.

version info:

:; ruby --version
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]
:; rails --version
Rails 3.2.8

    Figured it out myself, -b :: will make it listen on both IPv6 and IPv4 (depending on sysctl net.ipv6.bindv6only probably).
