FTP Server programmieren, Authentifikation...

Surkevin

Hallo!
Ich will einen kleinen FTP Server programmieren! Ich habe da ein Problem...wenn acceptet wird schicke ich "220 Connection accepted" alles schön und gut..dann bekomme ich vom Client USER Name...das kommt bei mir an und ich sage "331 Username ok need password" Doch dann macht der FTP Client nicht weiter! Woran kann das liegen?

Danke

Kevin
