xftp_home specifies an alternate directory for SFTP to create the ".ssh" subdirectory for keeping track of "known hosts". The default is $ENVHOME. This option is useful for web CGI scripts which run often under a user with no "home" directory. The format is: "/some/path/that/the/user/can/write/to".
Please report any bugs or feature requests to bug-ne...@rt.cpan.org, or through the web interface at =Net-xFTP. I will be notified, and then you'll automatically be notified of progress on your bug as I make changes.
