[INFO] multicast-FTP mit UDP für die FritzBox

[sf3978]

Mit dem Patch aus dem Anhang kann man mit Freetz, uftp (Client+Server+Proxy+Keytool) für die FritzBox kompilieren. Mit der Software kann man multicast-FTP mit UDP machen. Die Software gibt es auch für Windows. Der Client lauscht und der Server sendet die Daten. Ich habe auf der FritzBox den Client lauschen lassen und mit dem Server, vom PC (Linux), die Testdatei im unicast Modus (-U) übetragen:

-lauschender Client:

/var/mod/root # uftpd -d -n -D /var/media/ftp/uStor01 -L /var/media/ftp/uStor01/uftpd.log -S /var/media/ftp/uStor01/server.list -I 192.168.138.1 -M 232.2.3.1
