[erlang-questions] ip_v6_disabled cannot be set for ssh connection in OTP R15B01

[William Yangzhuwei]

hello,

Once I try to connect with ssh with ip_v6_disabled = true, like following

 ssh:connect("some hostname",2022,[{user,"user"},
 {password,"pwd"},
 {user_interaction,false},
 {user_dir,"/tmp/tmp.6xqteJfWII"},
 {silently_accept_hosts,true},
 {ip_v6_disabled,true}],infinity)

I will got some error return

{error,
                                            {eoptions,{ip_v6_disabled,true}}}


I have check the code of OTP,
These two lines looks strange.

handle_ssh_option({ip_v6_disabled, Value} = Opt) when is_function(Value) ->
    Opt;

Why it must be a function?

BTW, ip_v6_disabled = true works in R14B

That's a copy&paste error, fixed in this commit:

Thanks for your reply.

This fix will be included in next release then, I guess.
