unFTP Up

Arguments can be given to unFTP either via the command line or via environment variables. To show a list of available program arguments type the following:

unftp --help

To run passwordless unFTP with everything set to the defaults:

unftp --auth-type anonymous

Note

The --auth-type switch is required, but will be omitted in many other examples for brevity. Choose the appropriate authentication type for your use case—do not use anonymous unless explicitly intended.

This will start unFTP:

with a filesystem back-end rooted at your OS temporary directory.
the FTP control channel bound to 0.0.0.0:2121 and the data channel range set to 0.0.0.0 ports 49152..65535
authentication being anonymous i.e. clients can specify any username and password

Now serving data from your computer's temporary directory is not very useful so lets point it to a different directory by using the --root-dir argument. In addition, lets limit the data port range a bit:

unftp \
  -v \
  --root-dir=/home/unftp/data \
  --bind-address=0.0.0.0:2121 \
  --passive-ports=50000-51000
