1 # Example config file /etc/vsftpd/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 # Allow anonymous FTP? (Beware - allowed by default if you comment this out).
12 anonymous_enable=YES # 允許匿名登入ftp YES 必須大寫
13 #
14 # Uncomment this to allow local users to log in.
15 # When SELinux is enforcing check for SE bool ftp_home_dir
16 local_enable=YES # 是否支援本地使用者
17 #
18 # Uncomment this to enable any form of FTP write command.
19 write_enable=YES # 是否允許本地使用者寫入
20 #
21 # Default umask for local users is 077. You may wish to change this to 022,
22 # if your users expect that (022 is used by most other ftpd's)
23 local_umask=022
24 #
25 # Uncomment this to allow the anonymous FTP user to upload files. This only
26 # has an effect if the above global write enable is activated. Also, you will
27 # obviously need to create a directory writable by the FTP user.
28 # When SELinux is enforcing check for SE bool allow_ftpd_anon_write, allow_ftpd_full_access
29 #anon_upload_enable=YES
30 #
31 # Uncomment this if you want the anonymous FTP user to be able to create
32 # new directories.
33 #anon_mkdir_write_enable=YES
34 #
35 # Activate directory messages - messages given to remote users when they
36 # go into a certain directory.
37 dirmessage_enable=YES
38 #
39 # Activate logging of uploads/downloads.
40 xferlog_enable=YES
41 #
42 # Make sure PORT transfer connections originate from port 20 (ftp-data).
43 connect_from_port_20=YES
45 # If you want, you can arrange for uploaded anonymous files to be owned by
46 # a different user. Note! Using "root" for uploaded files is not
47 # recommended!
48 #chown_uploads=YES
49 #chown_username=whoever
50 #
51 # You may override where the log file goes if you like. The default is shown
52 # below.
53 #xferlog_file=/var/log/xferlog
54 #
55 # If you want, you can have your log file in standard ftpd xferlog format.
56 # Note that the default log file location is /var/log/xferlog in this case.
57 xferlog_std_format=YES
58 #
59 # You may change the default value for timing out an idle session.
60 #idle_session_timeout=600
61 #
62 # You may change the default value for timing out a data connection.
63 #data_connection_timeout=120
64 #
65 # It is recommended that you define on your system a unique user which the
66 # ftp server can use as a totally isolated and unprivileged user.
67 #nopriv_user=ftpsecure
68 #
69 # Enable this and the server will recognise asynchronous ABOR requests. Not
70 # recommended for security (the code is non-trivial). Not enabling it,
71 # however, may confuse older FTP clients.
72 #async_abor_enable=YES
73 #
74 # By default the server will pretend to allow ASCII mode but in fact ignore
75 # the request. Turn on the below options to have the server actually do ASCII
76 # mangling on files when in ASCII mode. The vsftpd.conf(5) man page explains
77 # the behaviour when these options are disabled.
78 # Beware that on some FTP servers, ASCII support allows a denial of service
79 # attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
80 # predicted this attack and has always been safe, reporting the size of the
81 # raw file.
82 # ASCII mangling is a horrible feature of the protocol.
83 #ascii_upload_enable=YES
84 #ascii_download_enable=YES
85 #
86 # You may fully customise the login banner string:
87 #ftpd_banner=Welcome to blah FTP service.
88 #
89 # You may specify a file of disallowed anonymous e-mail addresses. Apparently
90 # useful for combatting certain DoS attacks.
91 #deny_email_enable=YES
92 # (default follows)
93 #banned_email_file=/etc/vsftpd/banned_emails
94 #
95 # You may specify an explicit list of local users to chroot() to their home
96 # directory. If chroot_local_user is YES, then this list becomes a list of
97 # users to NOT chroot().
98 # (Warning! chroot'ing can be very dangerous. If using chroot, make sure that
99 # the user does not have write access to the top level directory within the
100 # chroot)
101 #chroot_local_user=YES
102 #chroot_list_enable=YES
103 # (default follows)
104 #chroot_list_file=/etc/vsftpd/chroot_list
105 #
106 # You may activate the "-R" option to the builtin ls. This is disabled by
107 # default to avoid remote users being able to cause excessive I/O on large
108 # sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
109 # the presence of the "-R" option, so there is a strong case for enabling it.
110 #ls_recurse_enable=YES
111 #
112 # When "listen" directive is enabled, vsftpd runs in standalone mode and
113 # listens on IPv4 sockets. This directive cannot be used in conjunction
114 # with the listen_ipv6 directive.
115 listen=NO
116 #
117 # This directive enables listening on IPv6 sockets. By default, listening
118 # on the IPv6 "any" address (::) will accept connections from both IPv6
119 # and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6
120 # sockets. If you want that (perhaps because you want to listen on specific
121 # addresses) then you must run two copies of vsftpd with two configuration
122 # files.
123 # Make sure, that one of the listen options is commented !!
124 listen_ipv6=YES
