SuSE FTP activation instance

Operating System: suse10 Enterprise Edition
1. Check whether the required FTP package has been activated in the system.
Rpm-Qa | grep vsftp
If not, manually install
Rpm-IVH vsftpd-2.0.4-19.18.suse.x86_64.rpm
2. After installing the play data packet, you need to change the configuration file.
Configuration file directory:/etc/vsftpd. conf
-----------------------------------------------------------------------------
Vsftpd has three server modes: Anonymous, local, and virtual. The configuration file of vsftpd is located in the/etc/directory named vsftpd. conf. The following describes the areas to be modified:
Remove the # Before local_enable = yes to make it available, indicating that local users are allowed to log on. Add the listen_port = 21 configuration item and set the listening port to 21. This step is optional, anonymous users are not allowed to log on,

Change the value of anonymous_enable = yes to no and set it as needed.
Restrict local users to access the file system
Chroot_local_user = Yes restrict local user browsing under the FTP root directory. After an FTP user logs on, the owner and permissions of the directory must be set through chown in the home user directory, in this way, you can upload and create files or directories. Other directories and files can be downloaded normally.

Restart the vsftpd service: Service vsftpd restart. Or, after/etc/init. d/vsftpd restart is started, log on to the local user userl and its password during the test.
Restrict some users to access the file system
Chroot_list_enable = Yes enable list (it cannot be enabled together with the previous command)
Chroot_list_file = % file path % restrict user list files
Connection restrictions
Max_client = % Number % maximum number of connections
Max_per_ip = % Number % maximum number of connections per IP
Anon_max_rate = % Number % anonymous user maximum rate unit: kbit/s
Local_max_rate = % Number % Local User Maximum rate unit: kbps

-----------------------------------
Vsftpd is compiled by myself. Many articles on the Forum said that the xinetd mode is used for compilation. change disable = No to yes in the D/vsftpd file!
Also, add Listen = yes to the/etc/vsftpd. conf file and change it to standalone independent mode!
500 Oops: cocould not bind listening IPv4 socket error:
Because xinetd has started vsftpd and vsftpd is set to stardalone mode, stop the xinetd service first, and stop the service xinetd; Service vsftpd restart
