The Solaris FTP client has been enhanced to include support for the following:
Using passive mode to connect to a remote host from behind a firewall
Restarting a failed transfer from the beginning of the transfer or from a certain offset
Setting the TCP window size to enhance the performance of file transfers
Detecting that the remote system is another UNIX system and setting the default transfer mode appropriately for optimized performance
For information on the ftp command, see the ftp(1) man page.
