[erlang-bugs] R13B04: ssh:connect to an IPv6 address doesn't work

It looks like you've found a bug.

%% ssh:connect/4

     DisableIpv6 =  proplists:get_value(ip_v6_disabled, Opts, false),
     Inet = inetopt(DisableIpv6),

Which invokes the local function:

inetopt(true) ->
inetopt(false) ->

I.e, the return values have been mixed up. If you try the following it 
should work for you:

  erl> ssh:connect("::1", 22, [{ip_v6_disabled, true}]).

But this needs to be sorted out in the SSH application.
