EHOSTUNREACH when a FTP connection cannot be established #5754
Description
Expected Behavior
Is it possible to make the error convey that the remote host is unavailable or unreachable like MRI does with EHOSTUNREACH?
I think that Errno::EBADF (Bad file descriptor - No message available) do not convey that the FTP server/host is unreachable.
I looked at #5709 (comment) and wonder if it is even possible to raise a EHOSTUNREACH.
Please feel free to close this if this cannot be considered an issue with JRuby.
JRuby:
jruby-9.2.7.0 :001 > require 'net/ftp'
=> true
jruby-9.2.7.0 :002 > Net::FTP.open('example.com', 'test', 'password') do |ftp_conn|
jruby-9.2.7.0 :003 > puts ftp_conn.nlst("*")
jruby-9.2.7.0 :004?> end
