[SOLVED] Cannot login to ftp

[krzd]

The output of nc -l -p21 after starting is immediatly:
Can't grab 0.0.0.0:21 with bind.

//edit: oh, it's because i had proftpd running, ok nc stops without any output, while the ftp client stops with:
Status: Verbinde mit 84.23.64.192:21...
Status: Verbindung hergestellt, warte auf Willkommensnachricht...
Fehler: Zeitüberschreitung der Verbindung
Fehler: Herstellen der Verbindung zum Server fehlgeschlagen
Translation: connecting with 84.23.64.192:21; connection established, waiting for welcome message; connection time-out; establishing connection to the server failed
