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 Access 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
