Timeout Maximum idle time in seconds. Setting idle
timeout to 0 disables the idle timer completely
(clients can stay connected for ever, without
sending data).
Anonymous FTP Enable anonymous FTP
Welcome message The welcome message which will be displayed
to the user when they initially login.
Permit root login Specifies whether it is allowed to login as supe-
ruser directly
Require valid shell Deny logins which do not have a valid shell
Bandwidth restriction Use the following bandwidth restriction: 0 KiB/s
means unlimited.
Passive FTP Use the following port range: In some cases you
have to specify passive ports range to by-pass
firewall limitations. Passive ports restricts the
range of ports from which the server will select
when sent the PASV command from a client.
The server will randomly choose a number from
within the specified range until an open port is
found. The port range selected must be in the
non-privileged range (eg. greater than or equal
to 1024). It is strongly recommended that the
chosen range be large enough to handle many
simultaneous passive connections (for example,
49152-65534, the IANA-registered ephemeral
port range).
Masquerade address If your host is acting as a NAT gateway or port
forwarder for the server, this option is useful
in order to allow passive transfers to work. You
have to use your public address and opening
the passive ports used on your firewall as well.
Specifies the amount of time, in seconds, be-
tween checking and updating the masquerade
address by resolving the IP address. Set this
value to 0 to disable this option.
