Minimal Telnet Server I wrote for a MUD backend.
go get github.com/BigJk/telly
package main
import (
"fmt"
"github.com/BigJk/telly"
"time"
)
func main() {
listener, err := telly.Listen(":5050")
if err != nil {
panic(err)
}
// If no message is received for 60 seconds close connection.
listener.SetTimeout(time.Second * 60)
for {
if conn, err := listener.Accept(); err == nil {
conn.SetMessageHandler(func(conn *telly.Conn, s string) {
fmt.Println(s)
_ = conn.Write(s)
})
conn.SetDisconnectHandler(func(conn *telly.Conn) {
fmt.Println(conn.RemoteAddr(), "disconnected")
})
fmt.Println(conn.RemoteAddr(), "connected")
}
}
}The Project might be RFC conform but seems abondoned and doesn't support two crucial features. There is no clear way to close a connection from the server side and no support for custom timeouts. Without custom timeouts it's easy to overflow a server with idle connections.
