Files may be transferred using server initiated (PORT) or client initiated (PASV) data connections. The enablepasv command enables PASV data connections while the disablepasv command enables PORT data connections. These commands do not apply to SSH based SFTP file transfers.

The syntax is

enablepasv;

disablepasv;

Some examples are

enablepasv; #enable PASV data connections

disablepasv; #enable PORT data connections
