Returns the ipv4_multicast_ttl data in sockopt as an integer.

sockopt = Socket::Option.ipv4_multicast_ttl(10)
p sockopt.ipv4_multicast_ttl => 10

Load an iseq object from binary format String object created by RubyVM::InstructionSequence.to_binary.

This loader does not have a verifier, so that loading broken/modified binary causes critical problem.

You should not load binary data provided by others. You should use binary data translated by yourself.

Creates a regular expression to match IPv4 addresses

Set the default value for the :argc_limit option.

See new(). The initial default value is 256.

Set the default value for the :id_conv option.

See new(). The initial default value is a DRbIdConv instance.

Check that a method is callable via dRuby.

obj is the object we want to invoke the method on. msg_id is the method name, as a Symbol.

If the method is an insecure method (see insecure_method?) a SecurityError is thrown. If the method is private or undefined, a NameError is thrown.

WARNING This method opens a serious security hole. Never use this method in production code.

Sets an output stream for debugging.

http = Net::HTTP.new(hostname)
http.set_debug_output $stderr
http.start { .... }

The default port for POP3 connections, port 110

The default port for POP3S connections, port 995

WARNING: This method causes a serious security hole. Use this method only for debugging.

Set an output stream for debugging.

Example

pop = Net::POP.new(addr, port)
pop.set_debug_output $stderr
pop.start(account, passwd) do |pop|

true if server advertises AUTH PLAIN. You cannot get valid value before opening SMTP session.

true if server advertises AUTH LOGIN. You cannot get valid value before opening SMTP session.

Returns supported authentication methods on this server. You cannot get valid value before opening SMTP session.

Enables SMTP/TLS (STARTTLS) for this object if server accepts. context is a OpenSSL::SSL::SSLContext object.

Opens a message writer stream and gives it to the block. The stream is valid only in the block, and has these methods:

puts(str = ”)

outputs STR and CR LF.

print(str)

outputs STR.

printf(fmt, *args)

outputs sprintf(fmt,*args).

write(str)

outputs STR and returns the length of written bytes.

<<(str)

outputs STR and returns self.

If a single CR (“r”) or LF (“n”) is found in the message, it is converted to the CR LF pair. You cannot send a binary message with this method.

Parameters

from_addr is a String representing the source mail address.

to_addr is a String or Strings or Array of Strings, representing the destination mail address or addresses.

Example

Net::SMTP.start('smtp.example.com', 25) do |smtp|
  smtp.open_message_stream('from@example.com', ['dest@example.com']) do |f|
    f.puts 'From: from@example.com'
    f.puts 'To: dest@example.com'
    f.puts 'Subject: test message'
    f.puts
    f.puts 'This is a test message.'
  end
end
