ftp implicit ssl connection

[gomess]

Hi, first of all sorry for my english ;-P Next... i'm trying to make a ftp client for linux that uses implicit SSLv23 connection, but i have a problem: when i connect to a server and the ssl connection is established i try to send a command but the server doesn't answer with any byte... Taking a look at the logs of other (windows) clients i've seen that the first command sent is the PBSZ command and i send it too, but i receive no answer... I tried all the ftp commands with the same result... what can i do ?   Thank U all :-)   Edo
