vsftpd.conf file

  1 # Example config file /etc/vsftpd.conf  2 #  3 # The default compiled in settings are fairly paranoid. This sample file  4 # loosens things up a bit, to make the ftp daemon more usable.  5 # Please see vsftpd.conf.5 for all compiled in defaults.  6 #  7 # READ THIS: This example file is NOT an exhaustive list of vsftpd options.  8 # Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's  9 # capabilities. 10 # 11 # 12 # Run standalone?  vsftpd can run either from an inetd or as a standalone 13 # daemon started from an initscript. 14 listen=NO 15 # 16 # This directive enables listening on IPv6 sockets. By default, listening 17 # on the IPv6 "any" address (::) will accept connections from both IPv6 18 # and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6 19 # sockets. If you want that (perhaps because you want to listen on specific 20 # addresses) then you must run two copies of vsftpd with two configuration 21 # files. 22 listen_ipv6=YES 23 # 24 # Allow anonymous FTP? (Disabled by default). 25 anonymous_enable=YES 26 27 no_anon_password=YES 28 29 ftp_username=ftp 30 anon_root=/var/ftp 31 32 # 33 # Uncomment this to allow local users to log in. 34 local_enable=YES 35 # 36 # Uncomment this to enable any form of FTP write command. 37 write_enable=YES 38 # 39 # Default umask for local users is 077.
