open

Function

The open command connects the FTP client and server.

Format

# Connect the FTP client to the FTP server based on the IPv4 address.

open [ ssl-policy policy-name ] [ -a source-ip-address | -i interface-type interface-number ] host-ip [ port-number ] [ public-net | vpn-instance vpn-instance-name ]

# Connect the FTP client to the FTP server based on the IPv6 address.

open [ ssl-policy policy-name ] ipv6 host-ipv6 [ port-number ]

# If the connection address is the IPv6 link-local address generated automatically by the interface of the remote IPv6 FTP server, the command format is as follows:

open [ ssl-policy policy-name ] ipv6 ipv6-linklocal-address -oi interface-type interface-number [ port-number ]

Parameters

Parameter	Description	Value
ssl-policy policy-name	Specifies the name of the SSL policy that provides the secure FTP function.	The value is a string of 1 to 23 case-insensitive characters without spaces.
-a source-ip-address	Specifies the source IP address for connecting to the FTP client. You are advised to use the loopback interface IP address.	-
-i interface-type interface-number	Specifies the source interface type and ID. You are advised to use the loopback interface. The IP address configured for this interface is the source IP address for sending packets. If no IP address is configured for the source interface, the FTP connection cannot be set up.	-
host-ip	Specifies the IP address or host name of the remote IPv4 FTP server.	The value is a string of 1 to 255 case-insensitive characters without spaces. When double quotation marks are used around the string, spaces are allowed in the string.
port-number	Specifies the port number of the FTP server.	The value is an integer that ranges from 1 to 65535. The default value is the standard port number 21.
public-net	Specifies the FTP server on the public network. You must set the public-net parameter when the FTP server IP address is a public network IP address.	-
vpn-instance vpn-instance-name	Specifies the name of the VPN instance where the FTP server is located.	The value must be an existing VPN instance name.
host-ipv6	Specifies the IP address or host name of the remote IPv6 FTP server.	The value is a string of 1 to 255 case-insensitive characters without spaces. When double quotation marks are used around the string, spaces are allowed in the string.
ipv6-linklocal-address	Specifies the IPv6 link-local address generated automatically by the interface of the remote IPv6 FTP server.	-
-oi	Indicates the outbound interface of the IPv6 link-local address.	-
interface-typeinterface-number	Specifies the outbound interface type and number of the IPv6 link-local address.	-

Usage Guidelines

Usage Scenario

You can run the open command in the FTP client view to connect the FTP client to the server to transmit files and manage files and directories of the FTP server.

Precautions

You can run the ftp command in the user view to connect the FTP client and server and enter the FTP client view.
Before enabling the FTP or FTPS function and specifying the ssl-policy policy-name parameter, you must first configure an SSL policy.
You can set the source IP address to the source or destination IP address in the ACL rule when the -a or -i parameter is specified on the IPv4 network. This shields the IP address differences and interface status impact, filters incoming and outgoing packets, and implements security authentication.
You can run the set net-manager vpn-instance command to configure the NMS management VPN instance before running the open command to connect the FTP client and server.
- If public-net or vpn-instance is not specified, the FTP client accesses the FTP server in the VPN instance managed by the NMS.
- If public-net is specified, the FTP client accesses the FTP server on the public network.
- If vpn-instance vpn-instance-name is specified, the FTP client accesses the FTP server in a specified VPN instance.
If the port number that the FTP server uses is non-standard, you must specify a standard port number; otherwise, the FTP server and client cannot be connected.
When you run the open command, the system prompts you to enter the user name and password for logging in to the FTP server. You can log in to the FTP client and enter the FTP client view if the user name and password are correct.
