Public bug reported:
Greetings,
pcsd does only bind to IPv6 instead of IPv4 and IPv6, if it is started
on a machine, which has active IPv6 support.

By default it should bind to all available IPv4 and IPv6 interfaces. Instead it
only bind to the IPv6:
----------------->%-----------------
netstat -ap |grep ruby
tcp6 0 0 [::]:2224 [::]:* LISTEN
12430/ruby
-----------------%<-----------------
After changing the following in the /usr/share/pcsd/ssl.rb, it binds to IPv4
and IPv6:
----------------->%-----------------
# diff /usr/share/pcsd/ssl.rb /usr/share/pcsd/ssl.rb.bak
50,51c50,51
< :BindAddress => 'nil',
< :Host => '*',
---
> :BindAddress => '::',
> :Host => '::',
-----------------%<-----------------
netstat -ap |grep ruby
tcp 0 0 *:2224 *:* LISTEN
12465/ruby
tcp6 0 0 [::]:2224 [::]:* LISTEN
12465/ruby
