Finally taking a proper look at this (these commands were an external submission I did the minimal cleanup pass to get it out of pending and haven't looked at since), and I am once again reminded that yes, FTP is an insane protocol. I thought PASV did in-band file transfer in the existing connection, but no it just means client dials a SECOND connection to a known port on the target, which yes requiresd Pauline Middelink's IP masquerading invention to parse the protocol to masquerade it: https://www.linuxjournal.com/article/5047 Which is why encrypted FTP never took off: because the masquerading module can't intercept and parse the protocol and add the temporary rule that this IP is allowed to open one connection to this port, presumably timing out eventually if they don't for long enough... What a mess. Rob _______________________________________________ Toybox mailing list Toybox@lists.landley.net http://lists.landley.net/listinfo.cgi/toybox-landley.net
