83 Pure-FTPd is a small, simple server for the old and hairy File Transfer
84 Protocol, designed to use less resources than older servers, be smaller
85 and very secure, and to never execute any external program.
86 It support most-used features and commands of FTP (including many mod‐
88 ern extensions), and leaves out everything which is deprecated, mean‐
89 ingless, insecure, or correlates with trouble.
90 IPv6 is fully supported.
92
95 -0 When a file is uploaded and there is already a previous version
96 of the file with the same name, the old file will neither get
97 removed nor truncated. Upload will take place in a temporary
98 file and once the upload is complete, the switch to the new ver‐
99 sion will be atomic. This option should not be used together
100 with virtual quotas.
101 -1 Add the PID to the syslog output. Ignored if -f none is set.
103 -2 file
105 When using TLS, set the path to the certificate file.
106 -4 Listen only to IPv4 connections.
108 -6 Listen only to IPv6 connections.
110 -a gid Regular users will be chrooted to their home directories, unless
112 they belong to the specified gid. Note that root is always
113 trusted, and that chroot() occurs only for anonymous ftp without
114 this option.
115 -A Chroot() everyone, but root.
117 -b Be broken. Turns on some compatibility hacks for shoddy clients,
119 and for broken Netfilter gateways.
120 -B Start the standalone server in background (daemonize).
122 -c clients
124 Allow a maximum of clients to be connected. clients must be at
125 least 1, and if you combine it with -p it will be forced down to
126 half the number of ports specified by -p. If more than clients
127 are connected, new clients are rejected at once, even clients
128 wishing to upload, or to log in as normal users. Therefore, it
129 is advisable to use -m as primary overload protection. The
130 default value is 50.
131 -C max connection per ip
133 Limit the number of simultaneous connections coming from the
134 same IP address. This is yet another very effective way to pre‐
135 vent stupid denial of services and bandwidth starvation by a
136 single user. It works only when the server is launched in
137 standalone mode (if you use a super-server, it is supposed to do
138 that). If the server is launched with -C 2 , it doesn't mean
139 that the total number of connection is limited to 2. But the
140 same client, coming from the same machine (or at least the same
141 IP), can't have more than two simultaneous connections. This
142 features needs some memory to track IP addresses, but it's rec‐
143 ommended to use it.
144 -d turns on debug logging. Every command is logged, except that the
146 argument to PASS is changed to "<password>". If you repeat -d ,
147 responses too are logged.
148 -e Only allow anonymous users to log in.
150 -E Only allow authenticated login. Anonymous users are prohibited.
152 -f facility
154 makes ftpd use facility for all syslog(3) messages. facility
155 defaults to ftp. The facility names are normally listed in
156 /usr/include/sys/syslog.h. Note that if -f is not the first
157 option on the command line, a couple of messages may be logged
158 to local2 before the -f option is parsed. Use -f none to dis‐
159 able logging.
160 -F fortunes file
162 Display a funny random message in the initial login banner. The
163 random cookies are extracted from a text file, in the standard
164 fortune format. If you installed the fortune package, you should
165 have a directory (usually /usr/share/fortune ) with binary files
166 ( xxxx.dat ) and text files (without the .dat extension).
167 -g pidfile
169 In standalone mode, write the pid to that file in instead of
170 /var/run/pure-ftpd.pid .
171 -G When this option is enabled, people can no more change the name
173 of already uploaded files, even if they own those files or their
174 directory.
175 -H Don't resolve host names ("192.0.34.166" will be logged instead
177 of "www.example.com"). It can significantly speed up connections
178 and reduce bandwidth usage on busy servers. Use it especially on
179 public FTP sites.
180 -i Disallow upload for anonymous users, whatever directory permis‐
182 sions are. This option is especially useful for virtual hosting,
183 to avoid your users create warez sites in their account.
184 -I timeout
186 Change the maximum idle time. The timeout is in minutes, and
187 defaults to 15.
188 -j If the home directory of a user doesn't exist, automatically
190 create it. The newly created home directory belongs to the user,
191 and permissions are set according to the current directory mask.
192 To avoid local attacks, the parent directory should never belong
193 to an untrusted user.
194 -J ciphers
196 Set the list of ciphers that will be accepted for TLS connec‐
197 tions.
198 -k percentage
200 Disallow upload if the partition is more than percentage full.
201 Example: -k 95 will ensure that your disk will never get filled
202 more than 95% by FTP users.
203 -K Allow users to resume and upload files, but NOT to delete them.
205 Directories can be removed, but only if they are empty.
206 -l authentication:file
208 Enable a new authentication method. It can be one of: -l unix
209 For standard (/etc/passwd) authentication. -l pam For PAM
210 authentication. -l ldap:LDAP config file For LDAP directories.
211 -l mysql:MySQL config file For MySQL databases. -l pgsql:Post‐
212 gres config file For Postgres databases. -l puredb:PureDB data‐
213 base file For PureDB databases. -l extauth:path to pure-authd
214 socket For external authentication handlers.
215 Different authentication methods can be mixed together. For
216 instance if you run the server with -lpuredb:/etc/pure-
217 ftpd/pwd.pdb -lmysql:/etc/pure-ftpd/my.cf -lunix Accounts will
218 first be authenticated from a PureDB database. If it fails, a
219 MySQL server will be asked. If the account is still not found is
220 the database, standard unix accounts will be scanned. Authenti‐
221 cation methods are tried in the order you give the -l options,
222 if you do not give -l, then the decision comes from configure,
223 if PAM is built in, it is used, if not, then UNIX (/etc/passwd)
224 is used by default.
225 See the README.LDAP and README.MySQL files for info about the
226 built-in LDAP and SQL directory support.
227 -L max files:max depth
229 Avoid denial-of-service attacks by limiting the number of dis‐
230 played files in a 'ls' and the maximum depth of a recursive
231 'ls'. Defaults are 2000:5 (2000 files displayed for a single
232 'ls' and walk through 5 subdirectories max).
233 -m load
235 Do not allow anonymous users to download files if the load is
236 above load when the user connects. Uploads and file listings are
237 still allowed, as are downloads by real users. The user is not
238 told about this until he/she tries to download a file.
239 -M Allow anonymous users to create directories.
241 -n maxfiles:maxsize
243 Enable virtual quotas When virtual quotas are enabled, .ftpquota
244 files are created, and the number of files for a user is
245 restricted to 'maxfiles'. The max total size of his directory is
246 also restricted to 'maxsize' Megabytes. Members of the trusted
247 group aren't subject to quotas.
248 -N NAT mode. Force active mode. If your FTP server is behind a NAT
250 box that doesn't support applicative FTP proxying, or if you use
251 port redirection without a transparent FTP proxy, use this.
252 Well... the previous sentence isn't very clear. Okay: if your
253 network looks like this:
254 FTP--NAT.gateway/router--Internet
255 and if you want people coming from the internet to have access
256 to your FTP server, please try without this option first. If
257 Netscape clients can connect without any problem, your NAT gate‐
258 way rulez. If Netscape doesn't display directory listings, your
259 NAT gateway sucks. Use -N as a workaround.
260 -o Enable pure-uploadscript.
262 -O format:log file
264 Record all file transfers into a specific log file, in an alter‐
265 native format. Currently, three formats are supported: CLF,
266 Stats, W3C and xferlog.
267 If you add
268 -O clf:/var/log/pureftpd.log
269 to your starting options, Pure-FTPd will log transfers in
270 /var/log/pureftpd.log in a format similar to the Apache web
271 server in default configuration.
272 If you add
273 -O stats:/var/log/pureftpd.log
274 to your starting options, Pure-FTPd will create accurate log
275 files designed for traffic analys software like ftpStats.
276 If you add
277 -O w3c:/var/log/pureftpd.log
278 to your starting options, Pure-FTPd will create W3C-conformant
279 log files.
280 For security purposes, the path must be absolute (eg.
281 /var/log/pureftpd.log, not ../log/pureftpd.log).
282 -p first:last
284 Use only ports in the range first to last inclusive for pas‐
285 sive-mode downloads. This means that clients will not try to
286 open connections to TCP ports outside the range first - last,
287 which makes pure-ftpd more compatible with packet filters. Note
288 that the maximum number of clients (specified with -c) is forced
289 down to (last + 1 - first)/2 if it is greater, as the default
290 is. (The syntax for the port range is, conveniently, the same as
291 that of iptables).
292 -P ip address or host name
294 Force the specified IP address in reply to a PASV/EPSV/SPSV com‐
295 mand. If the server is behind a masquerading (NAT) box that
296 doesn't properly handle stateful FTP masquerading, put the ip
297 address of that box here. If you have a dynamic IP address, you
298 can use a symbolic host name (probably the one of your gateway),
299 that will be resolved every time a new client will connect.
300 -q upload:download
302 Enable an upload/download ratio for anonymous users (ex: -q 1:5
303 means that 1 Mb of goodies have to be uploaded to leech 5 Mb).
304 -Q upload:download
306 Enable ratios for anonymous and non-anonymous users. If the -a
307 option is also used, users from the trusted group have no ratio.
308 -r Never overwrite existing files. Uploading a file whose name
310 already exists cause an automatic rename. Files are called
311 xyz.1, xyz.2, xyz.3, etc.
312 -R Disallow users (even non-anonymous ones) usage of the CHMOD com‐
314 mand. On hosting services, it may prevent newbies from doing
315 mistakes, like setting bad permissions on their home directory.
316 Only root can use CHMOD when this switch is enabled.
317 -s Don't allow anonymous users to retrieve files owned by "ftp"
319 (generally, files uploaded by other anonymous users).
320 -S [{ip address|hostname}] [,{port|service name}]
322 This option is only effective when the server is launched as a
323 standalone server. Connections are accepted on the specified IP
324 and port. IPv4 and IPv6 are supported. Numeric and fully-quali‐
325 fied host names are accepted. A service name (see /etc/services)
326 can be used instead of a numeric port number.
327 -t bandwidth
329 or -t upload bandwidth:download bandwidth Enable process prior‐
330 ity lowering and bandwidth throttling for anonymous users. Delay
331 should be in kilobytes/seconds.
332 -T bandwidth
334 or -T upload bandwidth:download bandwidth Enable process prior‐
335 ity lowering and bandwidth throttling for *ALL* users.
336 Pure-FTPd should have been explicitly compiled with throttling
337 support to have these flags work. It is possible to have dif‐
338 ferent bandwidth limits for uploads and for downloads. '-t' and
339 '-T' can indeed be followed by two numbers delimited by a column
340 (':'). The first number is the upload bandwidth and the next one
341 applies only to downloads. One of them can be left blank which
342 means infinity. A single number without any column means that
343 the same limit applies to upload and download.
344 -u uid Do not allow uids below uid to log in (typically, low-numbered
346 uids are used for administrative accounts). -u 100 is suffi‐
347 cient to deny access to all administrative accounts on many
348 linux boxes, where 99 is the last administrative account. Anony‐
349 mous FTP is allowed even if the uid of the ftp user is smaller
350 than uid. -u 1 denies access only to root accounts. The default
351 is to allow FTP access to all accounts.
352 -U umask files:umask dirs
354 Change the mask for creation of new files and directories. The
355 default are 133 (files are readable -but not writable- by other
356 users) and 022 (same thing for directory, with the execute bit
357 on). If new files should only be readable by the user, use
358 177:077. If you want uploaded files to be executable, use
359 022:022 (files will be readable by other people) or 077:077
360 (files will only be readable by their owner).
361 -v bonjour name
363 Set the Bonjour name of the service (only available on MacOS X
364 when Bonjour support is compiled in).
365 -V ip address
367 Allow non-anonymous FTP access only on this specific local IP
368 address. All other IP addresses are only anonymous. With that
369 option, you can have routed IPs for public access, and a local
370 IP (like 10.x.x.x) for administration. You can also have a
371 routable trusted IP protected by firewall rules, and only that
372 IP can be used to login as a non-anonymous user.
373 -w Enable support for the FXP protocol, for non-anonymous users
375 only.
376 -W Enable the FXP protocol for everyone. FXP IS AN UNSECURE PROTO‐
378 COL. NEVER ENABLE IT ON UNTRUSTED NETWORKS.
379 -x In normal operation mode, authenticated users can read/write
381 files beginning with a dot ('.'). Anonymous users can't, for
382 security reasons (like changing banners or a forgotten .rhosts).
383 When '-x' is used, authenticated users can download dot-files,
384 but not overwrite/create them, even if they own them. That way,
385 you can prevent hosted users from messing .qmail files.
386 -X This flag is identical to the previous one (writing dot-files is
388 prohibited), but in addition, users can't even *read* files and
389 directories beginning with a dot (like "cd .ssh").
390 -y per user max sessions:max anonymous sessions
392 This switch enables per-user concurrency limits. Two values are
393 separated by a column. The first one is the max number of con‐
394 current sessions for a single login. The second one is the maxi‐
395 mum number of anonoymous sessions.
396 -Y tls behavior
398 -Y 0 (default) disables TLS security mechanisms.
399 -Y 1 Accept both normal sessions and TLS ones.
400 -Y 2 refuses connections that aren't using TLS security mecha‐
401 nisms, including anonymous ones.
402 -Y 3 refuses connections that aren't using TLS security mecha‐
403 nisms, and refuse cleartext data channels as well.
404 The server must have been compiled with TLS support and a valid
405 certificate must be in place to accept encrypted sessions.
406 -z Allow anonymous users to read files and directories starting
408 with a dot ('.').
409 -Z Add safe guards against common customer mistakes (like chmod 0
411 on their own files) .
412
416 Some of the complexities of older servers are left out.
417 This version of pure-ftpd can use PAM for authentication. If you want
419 it to consult any files like /etc/shells or /etc/ftpd/ftpusers consult
420 pam docs. LDAP directories and SQL databases are also supported.
421 Anonymous users are authenticated in any of three ways:
423 1. The user logs in as "ftp" or "anonymous" and there is an account
425 called "ftp" with an existing home directory. This server does not ask
426 anonymous users for an email address or other password.
427 2. The user connects to an IP address which resolves to the name of a
429 directory in /etc/pure-ftpd/pure-ftpd (or a symlink in that directory
430 to a real directory), and there is an account called "ftp" (which does
431 not need to have a valid home directory). See Virtual Servers below.
432 Ftpd does a chroot(2) to the relevant base directory when an anonymous
434 user logs in.
435 Note that ftpd allows remote users to log in as root if the password is
437 known and -u not used.
438
441 If a user's home directory is /path/to/home/./, FTP sessions under that
442 UID will be chroot()ed. In addition, if a users's home directory is
443 /path/to/home/./directory the session will be chroot()ed to
444 /path/to/home and the FTP session will start in 'directory'.
445 As noted above, this pure-ftpd omits several features that are required
447 by the RFC or might be considered useful at first. Here is a list of
448 the most important omissions.
449 On-the-fly tar is not supported, for several reasons. I feel that users
451 who want to get many files should use a special FTP client such as
452 "mirror," which also supports incremental fetch. I don't want to either
453 add several hundred lines of code to create tar files or execute an
454 external tar. Finally, on-the-fly tar distorts log files.
455 On-the-fly compression is left out too. Most files on an FTP site are
457 compressed already, and if a file isn't, there presumably is a reason
458 why. (As for decompression: Don't FTP users waste bandwidth enough
459 without help from on-the-fly decompression?)
460
463 Shortcuts for the "cd" command can be set up if the server has been
464 compiled with the --with-diraliases feature.
465 To enable directory aliases, create a file called /etc/pure-
467 ftpd/pureftpd-dir-aliases and alternate lines of alias names and asso‐
468 ciated directories.
469
472 This server leaves out some of the commands and features that have been
473 used to subvert anonymous FTP servers in the past, but still you have
474 to be a little bit careful in order to support anonymous FTP without
475 risk to the rest of your files.
476 Make ~ftp and all files and directories below this directory owned by
478 some user other than "ftp," and only the .../incoming directory/direc‐
479 tories writable by "ftp." It is probably best if all directories are
480 writable only by a special group such as "ftpadmin" and "ftp" is not a
481 member of this group.
482 If you do not trust the local users, put ~ftp on a separate partition,
484 so local users can't hard-link unapproved files into the anonymous FTP
485 area.
486 Use of the -s option is strongly suggested. (Simply add "-s" to the end
488 of the ftpd line in /etc/inetd.conf to enable it.)
489 Most other FTP servers require that a number of files such as
491 ~ftp/bin/ls exist. This server does not require that any files or
492 directories within ~/ftp whatsoever exist, and I recommend that all
493 such unnecessary files are removed (for no real reason).
494 It may be worth considering to run the anonymous FTP service as a vir‐
496 tual server, to get automatic logins and to firewall off the FTP
497 address/port to which real users can log in.
498 If your server is a public FTP site, you may want to allow only 'ftp'
500 and 'anonymous' users to log in. Use the -e option for this. Real
501 accounts will be ignored and you will get a secure, anonymous-only FTP
502 server.
503
506 The files <ftproot>/.banner and .message are magical.
507 If there is a file called .banner in the root directory of the anony‐
509 mous FTP area, or in the root directory of a virtual host, and it is
510 shorter than 1024 bytes, it is printed upon login. (If the client does
511 not log in explicitly, and an implicit login is triggered by a CWD or
512 CDUP command, the banner is not printed. This is regrettable but hard
513 to avoid.)
514 If there is a file called .message in any directory and it is shorter
516 than 1024 bytes, that file is printed whenever a user enters that
517 directory using CWD or CDUP.
518
521 You can run several different anonymous FTP servers on one host, by
522 giving the host several IP addresses with different DNS names.
523 Here are the steps needed to create an extra server using an IP alias
525 on linux 2.4.x, called "ftp.example.com" on address 10.11.12.13. on the
526 IP alias eth0.
527 1. Create an "ftp" account if you do not have one. It it best if the
529 account does not have a valid home directory and shell. I prefer to
530 make /dev/null the ftp account's home directory and shell. Ftpd uses
531 this account to set the anonymous users' uid.
532 2. Create a directory as described in Anonymous FTP and make a symlink
534 called /etc/pure-ftpd/pure-ftpd/10.11.12.13 which points to this direc‐
535 tory.
536 3. Make sure your kernel has support for IP aliases.
538 4. Make sure that the following commands are run at boot:
540 /sbin/ifconfig eth0:1 10.11.12.13
542 That should be all. If you have problems, here are some things to try.
544 First, symlink /etc/pure-ftpd/pure-ftpd/127.0.0.1 to some directory and
546 say "ftp localhost". If that doesn't log you in, the problem is with
547 ftpd.
548 If not, "ping -v 10.11.12.13" and/or "ping -v ftp.example.com" from the
550 same host. If this does not work, the problem is with the IP alias.
551 Next, try "ping -v 10.11.12.13" from a host on the local ethernet, and
553 afterwards "/sbin/arp -a". If 10.11.12.13 is listed among the ARP
554 entries with the correct hardware address, the problem is probably with
555 the IP alias. If 10.11.12.13 is listed, but has hardware address
556 0:0:0:0:0:0, then proxy-ARP isn't working.
557 If none of that helps, I'm stumped. Good luck.
559 Warning: If you setup a virtual hosts, normal users will not be able to
561 login via this name, so don't create link/directory in /etc/pure-
562 ftpd/pure-ftpd for your regular hostname.
563
566 /etc/passwd is used via libc (and PAM is this case), to get the uid and
567 home directory of normal users, the uid and home directory of "ftp" for
568 normal anonymous ftp, and just the uid of "ftp" for virtual ftp hosts.
569 /etc/shadow is used like /etc/passwd if shadow support is enabled.
571 /etc/group is used via libc, to get the group membership of normal
573 users.
574 /proc/net/tcp is used to count existing FTP connections, if the -c or
576 -p options are used
577 /etc/pure-ftpd/pure-ftpd/<ip address> is the base directory for the <ip
579 address> virtual ftp server, or a symbolic link to its base directory.
580 Ftpd does a chroot(2) into this directory when a user logs in to <ip
581 address>, thus symlinks outside this directory will not work.
582 ~ftp is the base directory for "normal" anonymous FTP. Ftpd does a
584 chroot(2) into this directory when an anonymous user logs in, thus sym‐
585 links outside this directory will not work.

589 The behaviour of LIST and NLST is a tricky issue. Few servers send
590 RFC-compliant responses to LIST, and some clients depend on non-compli‐
591 ant responses.
592 This server uses glob(3) to do filename globbing.
594 The response to NLST is by default similar to that of ls(1), and that
596 to LIST is by default similar to that of ls -l or ls -lg on most Unix
597 systems, except that the "total" count is meaningless. Only regular
598 files, directories and symlinks are shown. Only important ls options
599 are supported:
600 -1 Undoes -l and -C.
602 -a lists even files/directories whose names begin with ".".
604 -C lists files in as many colums as will fit on the screen. Undoes
606 -1 and -l.
607 -d lists argument directories' names rather their contents.
609 -D List files beginning with a dot ('.') even when the client
611 doesn't append the -a option to the list command.
612 -F appends '*' to executable regular files, '@' to symlinks and '/'
614 to directories.
615 -l shows various details about the file, including file group. See
617 ls(1) for details. Undoes -1 and -C.
618 -r reverses the sorting order (modifies -S and -t and the default
620 alphabetical ordering).
621 -R recursively descends into subdirectories of the argument direc‐
623 tories.
624 -S Sorts by file size instead of by name. Undoes -t.
626 -t Sorts by file modification time instead of by name. Undoes -S.
