Reading from net.PacketConn about ipfix HOT 6 CLOSED

Yeah, the readme is outdated. This is better accomplished by doing the reading yourself and then using ParseBuffer. Probably ParseReader should not exist either, but now it does. :)

Hm. But how do i know, how big a buffer i should use? So i don't run into short read - malformed packet?

Oh, right. But with such a big buffer i'm getting unexpected EOF.
Sorry for bothering you, but what am i doing wrong?

package main

import (
    "net"
    "log"
    "fmt"
    "github.com/calmh/ipfix"
)

func main() {

  pc, err := net.ListenPacket("udp", ":2055")
  if err != nil {
    log.Fatal(err)
  }
  defer pc.Close()

  s := ipfix.NewSession()
  i := ipfix.NewInterpreter(s)

  buffer := make([]byte, 65507)

  for {
    pc.ReadFrom(buffer)

    msg, err := s.ParseBuffer(buffer)
    if err != nil {
        panic(err)
    }

    var fieldList []ipfix.InterpretedField
    for _, record := range msg.DataRecords {
        fieldList = i.InterpretInto(record, fieldList)
        fmt.Println(fieldList)
    }
  }
}

You need to only give it the part of the buffer that was actually read into. See the example I just wrote up in the readme in the commit linked above^ and see if that helps

Yep, that definitely helps. Thank you!
