The short answer is that it is not possible. It appears to be hard coded as 

-define(OPEN_TIMEOUT,60*1000). in ftp.erl

This is used directly in the gen_tcp:connect/4 call so it is not
configurable at runtime.

Your options are:

* Change the -define and recompile

* Modify ftp.erl to make it a configureable parameter..

* Ask Ericsson to change it in the next patch release.

If you fancy having a go at making it configurable you always have the
option to send it to  requesting that they
include your changes.

Rgds,
Sean
