Log IPs that connect to the telnet server

[ghost]

What is the best way to log IPs that connect to the telnet server. I've experimented with various ways but have been unable to do it so far. Here's a simple example.

package main

import (
"github.com/reiver/go-telnet"
"log"
)

var RBTHandler telnet.Handler = internalRBTHandler{}

type internalRBTHandler struct{}

func (handler internalRBTHandler) ServeTELNET(ctx telnet.Context, w telnet.Writer, r telnet.Reader) {
// How do I log the remote ip here?
log.Printf("%v\n", ctx)
}

func main() {
var handler telnet.Handler = RBTHandler
//var logger telnet.Logger

server := &telnet.Server{
	Addr:    ":2323",
	Handler: handler,
	//Logger:  logger,
}

err := server.ListenAndServe()
if nil != err {
	panic(err)
}

}
