- 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 &
