Help | Content Gateway | Version 8.1.x

Configuration Variable

proxy.config.ftp.
data_connection_mode

Specifies the FTP connection mode:

1 = PASV then PORT

proxy.config.ftp.
control_connection_
timeout

Specifies how long Content Gateway waits for a response from the FTP server.

proxy.config.ftp.
rc_to_switch_to_PORT

Specifies the response codes for which Content Gateway automatically fails over to the PORT command when PASV fails if the configuration variable proxy.config.ftp.
data_connection_mode is set to 1.

This variable is used for FTP requests from HTTP clients only.

proxy.config.ftp.
ftp_enabled

Enables (1) or disables (0) processing of FTP requests from FTP clients.

proxy.config.ftp.
cache_enabled

Enables (1) or disables (0) caching of FTP objects.

When this option is disabled, Content Gateway always serves FTP objects from the FTP server.

proxy.config.ftp.
file_fresh_mdtm_
checking_enabled

Only applies when FTP caching is enabled.

When Enabled (1), Content Gateway sends an 'MDTM' command before the 'RETR' command to get the last modified time of file(s).

If the file is in cache and the last_contact time is the same as 'MDTM' response, the proxy serves the cache file to the client.

proxy.config.ftp.
logging_enabled

Enables (1) or disables (0) logging of FTP transactions.

proxy.config.ftp.
proxy_server_port

Specifies the port used for FTP connections.

proxy.config.ftp.
open_lisn_port_mode

Specifies how FTP opens a listening port for a data transfer:

1 = The operating system chooses an available port. Content Gateway sends 0 and retrieves the new port number if the listen succeeds.

2 = The listening port is determined by the range of ports specified by the Content Gateway variables proxy.config.ftp.
min_lisn_port and proxy.config.
ftp.max_lisn_port, described below.

proxy.config.ftp.
min_lisn_port

Specifies the lowest port in the range of listening ports used by Content Gateway for data connections when the FTP client sends a PASV or Content Gateway sends a PORT to the FTP server.

proxy.config.ftp.
max_lisn_port

Specifies the highest port in the range of listening ports used by Content Gateway for data connections when the FTP client sends a PASV or Content Gateway sends a PORT to the FTP server.

proxy.config.ftp.
server_data_default_pasv

Specifies the default method used to set up server side data connections:

1 = Content Gateway sends a PASV to the FTP server and lets the FTP server open a listening port.

0 = Content Gateway tries PORT first (sets up a listening port on the proxy side of the connection).

proxy.config.ftp.
different_client_port_
ip_allowed

When enabled (1), Content Gateway can connect to a machine other than the one on which the FTP client is running to establish a data connection.

The FTP client uses PORT to set up a listening port on its side and allows Content Gateway to connect to that port to establish the data connection (used to transfer files). When setting up the listening port, an FTP client specifies the IP address and port number for the listening port. If this variable is set to 0 (zero), Content Gateway cannot connect to the FTP client if the IP address sent by the client is different from the IP address of the machine running the FTP client.

proxy.config.ftp.
try_pasv_times

Specifies the number of times Content Gateway can try to open a listening port when the FTP client sends a PASV.

proxy.config.ftp.
try_port_times

Specifies the maximum number of times Content Gateway can try to open a listening port when sending a PORT to the FTP server.

proxy.config.ftp.
try_server_ctrl_connect_
times

Specifies the maximum number of times Content Gateway can try to connect to the FTP server's control listening port.

proxy.config.ftp.
try_server_data_connect_
times

Specifies the maximum number of times Content Gateway can try to connect to the FTP server's data listening port when it sends a PASV to the FTP server and gets the IP/listening port information.

proxy.config.ftp.
try_client_data_connect_
times

Specifies the maximum number of times Content Gateway can try to connect to the FTP client's data listening port when the FTP client sends a PORT with the IP/listening port information.

proxy.config.ftp.
client_ctrl_no_activity_
timeout

Specifies the inactivity timeout, in seconds, for the FTP client control connection.

proxy.config.ftp.
client_ctrl_active_
timeout

Specifies the active timeout, in seconds, for the FTP client control connection.

proxy.config.ftp.
server_ctrl_no_activity_
timeout

Specifies the inactivity timeout, in seconds, for the FTP server control connection.

proxy.config.ftp.
server_ctrl_active_
timeout

Specifies the active timeout, in seconds, for the FTP server control connection.

proxy.config.ftp.
client_data_no_activity_
timeout

Specifies the maximum time, in seconds, that a client FTP data transfer connection can be idle before it is aborted.

proxy.config.ftp.
client_data_active_
timeout

Specifies the maximum time, in seconds, of an FTP data transfer connection from a client.

proxy.config.ftp.
server_data_no_activity_
timeout

Specifies the maximum time, in seconds, that a server FTP data transfer connection can be idle before it is aborted.

proxy.config.ftp.
server_data_active_
timeout

Specifies the maximum time, in seconds, of an FTP data transfer connection from a server.

proxy.config.ftp.
pasv_accept_timeout

Specifies the timeout value for a listening data port in Content Gateway (for PASV, the client data connection).

proxy.config.ftp.
port_accept_timeout

Specifies the timeout value for a listening data port in Content Gateway (for PORT, the server data connection).

proxy.config.ftp.
share_ftp_server_ctrl_
enabled

Enables (1) or disables (0) sharing the server control connections among multiple anonymous FTP clients.

proxy.config.ftp.share_
only_after_session_end

Specifies how an FTP server control connection is shared between different FTP client sessions:

1 = the FTP server control connection can be used by another FTP client session only when the FTP client session is complete (typically, when the FTP client sends out a QUIT command).

0 = the FTP server control connection can be used by another FTP client session only if the FTP client session is not actively using the FTP server connection: for example, if the request is a cache hit or during an idle session.

proxy.config.ftp.server_
ctrl_keep_alive_no_
activity_timeout

Specifies the timeout value when the FTP server control connection is not used by any FTP clients.

proxy.config.ftp.
reverse_ftp_enabled

proxy.config.ftp.
login_info_fresh_in_
cache_time

Specifies how long the 220/230 responses (login messages) can stay fresh in the cache.

proxy.config.ftp.data_
source_port_20_enabled

When enabled (1), bind to source port 20 for outgoing data transfer connections to Active mode FTP clients.

proxy.config.ftp.
directory_listing_fresh_in_cache_time

Specifies how long directory listings can stay fresh in the cache.

Specifies how long FTP files can stay fresh in the cache.
