Make sure the trust directory exists. If it does exist, make sure it’s actually a directory. If not, then create it with the appropriate permissions.

Creates a new Socket::Option object for IP_MULTICAST_TTL.
The size is dependent on the platform.
p Socket::Option.ipv4_multicast_ttl(10) #=> #<Socket::Option: INET IP MULTICAST_TTL 10>
Returns the ipv4_multicast_ttl data in sockopt as an integer.
sockopt = Socket::Option.ipv4_multicast_ttl(10) p sockopt.ipv4_multicast_ttl => 10
Creates a new Socket::Option object for IP_MULTICAST_LOOP.
The size is dependent on the platform.
sockopt = Socket::Option.int(:INET, :IPPROTO_IP, :IP_MULTICAST_LOOP, 1) p sockopt.int => 1 p Socket::Option.ipv4_multicast_loop(10) #=> #<Socket::Option: INET IP MULTICAST_LOOP 10>
Returns the ipv4_multicast_loop data in sockopt as an integer.
sockopt = Socket::Option.ipv4_multicast_loop(10) p sockopt.ipv4_multicast_loop => 10
Creates a regular expression to match IPv4 addresses
Returns the max number of flags interned to symbols.
