Option:

connect-timeout

Previous versions of the program used a single timeout value for everything. You can now have different values for different operations. However, you probably do not need to change these from the defaults unless you have special requirements.

 

The connect-timeout variable controls how long to wait, in seconds, for a connection establishment to complete before considering it hopeless. You can choose to not use a timeout at all by setting this to -1.

control-timeout

This is the timer used when ncftp sends an FTP command over the control connection to the remote server. If the server hasn't replied in that many seconds, it considers the session lost.

xfer-timeout

This timer controls how long to wait for data blocks to complete. Don't set this too low or else your transfers will timeout without completing.
