# Allow ftp-proxy to start up in two different ways. The typical behavior
|
|
# is to start up one instance of ftp-proxy by setting ftpproxy_enable and
|
|
# ftpproxy_flags. The alternate behavior allows multiple instances of ftp-
|
|
# proxy to be started, allowing different types of proxy behavior. To use the
|
|
# new behavior, a list of instances must be defined, and a list of flags for
|
|
# each instance. For example, if we want to start two instances of ftp-proxy,
|
|
# foo and bar, we would set the following vars.
|
|
# ftpproxy_enable="YES"
|
|
# ftpproxy_instances="foo bar"

# ftpproxy_foo="<arguments for foo>"
