Establishing An Ftp Connection - H3C S5500-HI Series Fundamentals Configuration Manual

Establishing an FTP connection

Before you can access the FTP server, you must establish a connection from the FTP client to the FTP
server. You can either use the ftp command to establish the connection directly or use the open
command in FTP client view to establish the connection.
When using the ftp or ftp client source command, you can specify the source interface (such as a
loopback) or source IP address. The primary IP address of the specified source interface or the specified
source IP address is used as the source IP address of sent FTP packets.
The FTP client follows these rules to select the source IP address of packets sent to the FTP server:
If no source IP address is specified, the IP address of the output interface of the route to the server
•
is used as the source IP address.
The source IP address specified with the ftp client source or ftp command is used.
•
If you first use the ftp client source command to specify a source IP address and then use the ftp
•
command to specify another source IP address, the latter is used.
• The source IP address specified with the ftp client source command applies to all FTP connections
while the one specified with the ftp command applies to the current FTP connection only.
Follow these steps to establish an IPv4 FTP connection:
To do...
Enter system view
Specify the source IP address of
sent FTP packets
Return to user view
Log in to the remote FTP server
directly in user view
Log in to the remote FTP server
indirectly in FTP client view
NOTE:
If there is not a primary IP address configured on the specified source interface, you cannot establish an
•
FTP connection.
If you use the ftp client source command to configure a source interface and then use it to configure a
•
source IP address, the source IP address overwrites the source interface, and vice versa.
Follow these steps to establish an IPv6 FTP connection:
Use the command...
system-view
ftp client source { interface
interface-type interface-number |
ip source-ip-address }
quit
ftp [ server-address [ service-port ]
[ vpn-instance vpn-instance-name ]
[ source { interface interface-type
interface-number | ip
source-ip-address } ] ]
ftp
open server-address [ service-port ]

Remarks
—
Optional
By default, the source IP address is
determined by the route from the
FTP client to the FTP server.
—
Use either approach.
The ftp command is available in
user view, and the open command
is available in FTP client view.
