Neither method after Connect and Login works

[wzup]

All these methods throw 230 error:

ftp.Cwd("/")
ftp.Pwd()
ftp.List("/")

I want to connect to IMDB ftp, ftp://ftp.fu-berlin.de. I'm trying to use your package.

Here is an example of the error:

$ read_db
List Error
panic: 230 FTP.FU-Berlin.DE login ok.


goroutine 1 [running]:
main.main()
        C:/Users/user/sbox/go/src/bitbucket.org/wzup/read_db/readDb.go:51 +0x47b

Here is my code, just a copy/paste of your example:

package main
import (
    "fmt"
    "github.com/dutchcoders/goftp"
)
func main() {

    /**
     * dutchcoders/goftp
     */
    var err error
    var ftp *goftp.FTP

    // For debug messages: goftp.ConnectDbg("ftp.server.com:21")
    if ftp, err = goftp.Connect("ftp.fu-berlin.de:21"); err != nil {
        fmt.Println("Connect Error")
        panic(err)
    }

    defer ftp.Close()

    if err = ftp.Login("admin", "sdkjcfnjoindsio"); err != nil {
        fmt.Println("Login Error")
        panic(err)
    }

    if err = ftp.Cwd("/"); err != nil {
        fmt.Println("Cwd Error")
        panic(err)
    }

    var curpath string
    if curpath, err = ftp.Pwd(); err != nil {
        fmt.Println("Pwd Error")
        panic(err)
    }
    fmt.Printf("Current path: %s", curpath)

    var files []string
    if files, err = ftp.List("/"); err != nil {
        fmt.Println("List Error")
        panic(err)
    }
    fmt.Println(files)
}

What do I do wrong? Why I cannot get an access to ftp server and see and download its contents?

server sent multiline response with blank line before

230 FTP.FU-Berlin.DE login ok.

This line break reading lines when match blank line https://github.com/dutchcoders/goftp/blob/master/ftp.go#L282

when then you send Cwd you recive unexpexted 230 FTP.FU-Berlin.DE login ok.

That's why :)

@VincenzoLaSpesa why did you skip response lines with len <4 ?

[VincenzoLaSpesa]

Because the ftp standard says that a response should begin with 3 digit, than a space, then the message as a string.

Try your server with
https://ftptest.net/

You'll get an:

Error: Reply too short. Expecting 3 digit reply code followed by space followed by description

That server is not standard.

I'll try to make it work on my fork (https://github.com/VincenzoLaSpesa/goftp)
I have a new "uglyServer" to test.
