vsftpd-1.1.3配制实例之二：INTERNET_SITE_NOINETD

　　This example shows how to run vsftpd in "standalone" mode - i.e. without
　　needing to run an inetd of some kind (inetd, xinetd, tcpserver etc).
　　vsftpd has supported standalone mode since v1.1.0.
　　With the release of v1.1.3, the feature list of standalone mode has grown so
　　that large internet sites no longer need to use an inetd.
　　Previously, large internet sites were forced to use xinetd for the important
　　feature of "limit number of concurrent connections from a single IP address".
　　Unfortunately, there seem to be xinetd stability issues - various larger
　　sites are reporting that xinetd's session counting can go wrong and incorrectly
　　kick off users because it thinks the FTP site is full when it is not.
　　vsftpd now natively handles maximum session counts and maximum session per IP
　　counts. It can also do native aclearcase/" target="_blank" >ccess control via tcp_wrappers integration and
　　even per-connect-IP configurability.
　　To use this example config:
　　1) Copy the vsftpd.conf file in this directory to /etc/vsftpd.conf.
　　2) Start up vsftpd, e.g.
　　vsftpd &
　　3) That should be it!
　　The example vsftpd.conf is based on the vsftpd.conf from the INTERNET_SITE
　　example. Let's look at the differences (at the top):
　　# Standalone mode
　　listen=YES
　　This tells vsftpd to run in standalone mode. Do NOT try and run vsftpd from
　　an inetd with this option set - it won't work, you may well get 500 OOPS:
　　could not bind listening socket.
　　max_clients=200
　　max_per_ip=4
　　The maximum number of session is 200 (new clients will get refused with a
　　busy message). The maximum number of sessions from a single IP is 4 (the
　　5th connect will get refused with a suitable message).
　　One further note on standalone mode, regarding virtual IPs. This is very
　　easy - just run one copy of vsftpd per virtual IP (remembering to give each
　　a separate config file on the command line).
　　Distinguish which vsftpd is for which virtual IP with a setting like this
　　in the vsftpd.conf:
　　listen_address=192.168.1.2
　　And launch vsftpd with a specific config file like this:
　　vsftpd /etc/vsftpd.conf.site1 &
　　vsftpd.conf
　　# Standalone mode
　　listen=YES
　　max_clients=200
　　max_per_ip=4
　　# Access rights
　　anonymous_enable=YES
　　local_enable=NO
　　write_enable=NO
　　anon_upload_enable=NO
　　anon_mkdir_write_enable=NO
　　anon_other_write_enable=NO
　　# Security
　　anon_world_readable_only=YES
　　connect_from_port_20=YES
　　hide_ids=YES
　　pasv_min_port=50000
　　pasv_max_port=60000
　　# Features
　　xferlog_enable=YES
　　ls_recurse_enable=NO
　　ascii_download_enable=NO
　　async_abor_enable=YES
　　# Performance
　　one_process_model=YES
　　idle_session_timeout=120
　　data_connection_timeout=300
　　accept_timeout=60
　　connect_timeout=60
　　anon_max_rate=50000
