my own ftp client waits on connect... please help

I'm writing my own ftp client, after I send the

user anonymous
pass nobody@
type i
pasv

I get back ip address and port number, after the manipulation of the
port number, if I try to connect, my program just waits there...

If I do the same thing in telnet, it works good. Any idea why its
happening like that...??

I'm calculating the port numbers correctly... and my parameters to
connect are correct too.. has double checked this...

Any help is greatly appreciated.

Thx,
-Amit

Also, If I look in tcpdump, there is no response for the connect
request from the server. Any idea why its happening like that.
