84 Pure-FTPd is a small, simple server for the old and hairy File Transfer
85 Protocol, designed to use less resources than older servers, be smaller
86 and very secure, and to never execute any external program.
87 It support most-used features and commands of FTP (including many mod‐
89 ern extensions), and leaves out everything which is deprecated, mean‐
90 ingless, insecure, or correlates with trouble.
91 IPv6 is fully supported.
93
96 -0 When a file is uploaded and there is already a previous version
97 of the file with the same name, the old file will neither get
98 removed nor truncated. Upload will take place in a temporary
99 file and once the upload is complete, the switch to the new ver‐
100 sion will be atomic. This option should not be used together
101 with virtual quotas.
102 -1 Add the PID to the syslog output. Ignored if -f none is set.
104 -2 cert_file[,key_file]
106 When using TLS, set the path to the certificate file. The cer‐
107 tificate and its key can be be bundled into a single file, or
108 the key can be in a distinct file.
109 -3 path
111 Path to the pure-certd UNIX socket.
112 -4 Listen only to IPv4 connections.
114 -6 Listen only to IPv6 connections.
116 -a gid Regular users will be chrooted to their home directories, unless
118 they belong to the specified gid. Note that root is always
119 trusted, and that chroot() occurs only for anonymous ftp without
120 this option.
121 -A Chroot() everyone, but root.
123 -b Be broken. Turns on some compatibility hacks for shoddy clients,
125 and for broken Netfilter gateways.
126 -B Start the standalone server in background (daemonize).
128 -c clients
130 Allow a maximum of clients to be connected. clients must be at
131 least 1, and if you combine it with -p it will be forced down to
132 half the number of ports specified by -p. If more than clients
133 are connected, new clients are rejected at once, even clients
134 wishing to upload, or to log in as normal users. Therefore, it
135 is advisable to use -m as primary overload protection. The de‐
136 fault value is 50.
137 -C max connection per ip
139 Limit the number of simultaneous connections coming from the
140 same IP address. This is yet another very effective way to pre‐
141 vent stupid denial of services and bandwidth starvation by a
142 single user. It works only when the server is launched in
143 standalone mode (if you use a super-server, it is supposed to do
144 that). If the server is launched with -C 2 , it doesn't mean
145 that the total number of connection is limited to 2. But the
146 same client, coming from the same machine (or at least the same
147 IP), can't have more than two simultaneous connections. This
148 features needs some memory to track IP addresses, but it's rec‐
149 ommended to use it.
150 -d turns on debug logging. Every command is logged, except that the
152 argument to PASS is changed to "<password>". If you repeat -d ,
153 responses too are logged.
154 -e Only allow anonymous users to log in.
156 -E Only allow authenticated login. Anonymous users are prohibited.
158 -f facility
160 makes ftpd use facility for all syslog(3) messages. facility
161 defaults to ftp. The facility names are normally listed in
162 /usr/include/sys/syslog.h. Note that if -f is not the first op‐
163 tion on the command line, a couple of messages may be logged to
164 local2 before the -f option is parsed. Use -f none to disable
165 logging.
166 -F fortunes file
168 Display a funny random message in the initial login banner. The
169 random cookies are extracted from a text file, in the standard
170 fortune format. If you installed the fortune package, you should
171 have a directory (usually /usr/share/fortune ) with binary files
172 ( xxxx.dat ) and text files (without the .dat extension).
173 -g pidfile
175 In standalone mode, write the pid to that file in instead of
176 /var/run/pure-ftpd.pid .
177 -G When this option is enabled, people can no more change the name
179 of already uploaded files, even if they own those files or their
180 directory.
181 -H Don't resolve host names ("192.0.34.166" will be logged instead
183 of "www.example.com"). It can significantly speed up connections
184 and reduce bandwidth usage on busy servers. Use it especially on
185 public FTP sites.
186 -i Disallow upload for anonymous users, whatever directory permis‐
188 sions are. This option is especially useful for virtual hosting,
189 to avoid your users create warez sites in their account.
190 -I timeout
192 Change the maximum idle time. The timeout is in minutes, and de‐
193 faults to 15.
194 -j If the home directory of a user doesn't exist, automatically
196 create it. The newly created home directory belongs to the user,
197 and permissions are set according to the current directory mask.
198 To avoid local attacks, the parent directory should never belong
199 to an untrusted user.
200 -J ciphers
202 Set the list of ciphers that will be accepted for TLS connec‐
203 tions.
204 -k percentage
206 Disallow upload if the partition is more than percentage full.
207 Example: -k 95 will ensure that your disk will never get filled
208 more than 95% by FTP users.
209 -K Allow users to resume and upload files, but NOT to delete them.
211 Directories can be removed, but only if they are empty.
212 -l authentication:file
214 Enable a new authentication method. It can be one of: -l unix
215 For standard (/etc/passwd) authentication. -l pam For PAM au‐
216 thentication. -l ldap:LDAP config file For LDAP directories.
217 -l mysql:MySQL config file For MySQL databases. -l pgsql:Post‐
218 gres config file For Postgres databases. -l puredb:PureDB data‐
219 base file For PureDB databases. -l extauth:path to pure-authd
220 socket For external authentication handlers.
221 Different authentication methods can be mixed together. For in‐
222 stance if you run the server with -lpuredb:/etc/pure-
223 ftpd/pwd.pdb -lmysql:/etc/pure-ftpd/my.cf -lunix Accounts will
224 first be authenticated from a PureDB database. If it fails, a
225 MySQL server will be asked. If the account is still not found is
226 the database, standard unix accounts will be scanned. Authenti‐
227 cation methods are tried in the order you give the -l options,
228 if you do not give -l, then the decision comes from configure,
229 if PAM is built in, it is used, if not, then UNIX (/etc/passwd)
230 is used by default.
231 See the README.LDAP and README.MySQL files for info about the
232 built-in LDAP and SQL directory support.
233 -L max files:max depth
235 Avoid denial-of-service attacks by limiting the number of dis‐
236 played files in a 'ls' and the maximum depth of a recursive
237 'ls'. Defaults are 2000:5 (2000 files displayed for a single
238 'ls' and walk through 5 subdirectories max).
239 -m load
241 Do not allow anonymous users to download files if the load is
242 above load when the user connects. Uploads and file listings are
243 still allowed, as are downloads by real users. The user is not
244 told about this until he/she tries to download a file.
245 -M Allow anonymous users to create directories.
247 -n maxfiles:maxsize
249 Enable virtual quotas When virtual quotas are enabled, .ftpquota
250 files are created, and the number of files for a user is re‐
251 stricted to 'maxfiles'. The max total size of his directory is
252 also restricted to 'maxsize' Megabytes. Members of the trusted
253 group aren't subject to quotas.
254 -N NAT mode. Force active mode. If your FTP server is behind a NAT
256 box that doesn't support applicative FTP proxying, or if you use
257 port redirection without a transparent FTP proxy, use this.
258 Well... the previous sentence isn't very clear. Okay: if your
259 network looks like this:
260 FTP--NAT.gateway/router--Internet
261 and if you want people coming from the internet to have access
262 to your FTP server, please try without this option first. If
263 Netscape clients can connect without any problem, your NAT gate‐
264 way rulez. If Netscape doesn't display directory listings, your
265 NAT gateway sucks. Use -N as a workaround.
266 -o Enable pure-uploadscript.
268 -O format:log file
270 Record all file transfers into a specific log file, in an alter‐
271 native format. Currently, three formats are supported: CLF,
272 Stats, W3C and xferlog.
273 If you add
274 -O clf:/var/log/pureftpd.log
275 to your starting options, Pure-FTPd will log transfers in
276 /var/log/pureftpd.log in a format similar to the Apache web
277 server in default configuration.
278 If you add
279 -O stats:/var/log/pureftpd.log
280 to your starting options, Pure-FTPd will create accurate log
281 files designed for traffic analys software like ftpStats.
282 If you add
283 -O w3c:/var/log/pureftpd.log
284 to your starting options, Pure-FTPd will create W3C-conformant
285 log files.
286 For security purposes, the path must be absolute (eg.
287 /var/log/pureftpd.log, not ../log/pureftpd.log).
288 -p first:last
290 Use only ports in the range first to last inclusive for pas‐
291 sive-mode downloads. This means that clients will not try to
292 open connections to TCP ports outside the range first - last,
293 which makes pure-ftpd more compatible with packet filters. Note
294 that the maximum number of clients (specified with -c) is forced
295 down to (last + 1 - first)/2 if it is greater, as the default
296 is. (The syntax for the port range is, conveniently, the same as
297 that of iptables).
298 -P ip address or host name
300 Force the specified IP address in reply to a PASV/EPSV command.
301 If the server is behind a masquerading (NAT) box that doesn't
302 properly handle stateful FTP masquerading, put the ip address of
303 that box here. If you have a dynamic IP address, you can use a
304 symbolic host name (probably the one of your gateway), that will
305 be resolved every time a new client will connect.
306 -q upload:download
308 Enable an upload/download ratio for anonymous users (ex: -q 1:5
309 means that 1 Mb of goodies have to be uploaded to leech 5 Mb).
310 -Q upload:download
312 Enable ratios for anonymous and non-anonymous users. If the -a
313 option is also used, users from the trusted group have no ratio.
314 -r Never overwrite existing files. Uploading a file whose name al‐
316 ready exists cause an automatic rename. Files are called xyz.1,
317 xyz.2, xyz.3, etc.
318 -R Disallow users (even non-anonymous ones) usage of the CHMOD com‐
320 mand. On hosting services, it may prevent newbies from doing
321 mistakes, like setting bad permissions on their home directory.
322 Only root can use CHMOD when this switch is enabled.
323 -s Don't allow anonymous users to retrieve files owned by "ftp"
325 (generally, files uploaded by other anonymous users).
326 -S [{ip address|hostname}] [,{port|service name}]
328 This option is only effective when the server is launched as a
329 standalone server. Connections are accepted on the specified IP
330 and port. IPv4 and IPv6 are supported. Numeric and fully-quali‐
331 fied host names are accepted. A service name (see /etc/services)
332 can be used instead of a numeric port number.
333 -t bandwidth
335 or -t upload bandwidth:download bandwidth Enable process prior‐
336 ity lowering and bandwidth throttling for anonymous users. Delay
337 should be in kilobytes/seconds.
338 -T bandwidth
340 or -T upload bandwidth:download bandwidth Enable process prior‐
341 ity lowering and bandwidth throttling for *ALL* users.
342 Pure-FTPd should have been explicitly compiled with throttling
343 support to have these flags work. It is possible to have dif‐
344 ferent bandwidth limits for uploads and for downloads. '-t' and
345 '-T' can indeed be followed by two numbers delimited by a column
346 (':'). The first number is the upload bandwidth and the next one
347 applies only to downloads. One of them can be left blank which
348 means infinity. A single number without any column means that
349 the same limit applies to upload and download.
350 -u uid Do not allow uids below uid to log in (typically, low-numbered
352 uids are used for administrative accounts). -u 100 is suffi‐
353 cient to deny access to all administrative accounts on many
354 linux boxes, where 99 is the last administrative account. Anony‐
355 mous FTP is allowed even if the uid of the ftp user is smaller
356 than uid. -u 1 denies access only to root accounts. The default
357 is to allow FTP access to all accounts.
358 -U umask files:umask dirs
360 Change the mask for creation of new files and directories. The
361 default are 133 (files are readable -but not writable- by other
362 users) and 022 (same thing for directory, with the execute bit
363 on). If new files should only be readable by the user, use
364 177:077. If you want uploaded files to be executable, use
365 022:022 (files will be readable by other people) or 077:077
366 (files will only be readable by their owner).
367 -v bonjour name
369 Set the Bonjour name of the service (only available on MacOS X
370 when Bonjour support is compiled in).
371 -V ip address
373 Allow non-anonymous FTP access only on this specific local IP
374 address. All other IP addresses are only anonymous. With that
375 option, you can have routed IPs for public access, and a local
376 IP (like 10.x.x.x) for administration. You can also have a
377 routable trusted IP protected by firewall rules, and only that
378 IP can be used to login as a non-anonymous user.
379 -w Enable support for the FXP protocol, for non-anonymous users
381 only.
382 -W Enable the FXP protocol for everyone. FXP IS AN UNSECURE PROTO‐
384 COL. NEVER ENABLE IT ON UNTRUSTED NETWORKS.
385 -x In normal operation mode, authenticated users can read/write
387 files beginning with a dot ('.'). Anonymous users can't, for se‐
388 curity reasons (like changing banners or a forgotten .rhosts).
389 When '-x' is used, authenticated users can download dot-files,
390 but not overwrite/create them, even if they own them. That way,
391 you can prevent hosted users from messing .qmail files.
392 -X This flag is identical to the previous one (writing dot-files is
394 prohibited), but in addition, users can't even *read* files and
395 directories beginning with a dot (like "cd .ssh").
396 -y per user max sessions:max anonymous sessions
398 This switch enables per-user concurrency limits. Two values are
399 separated by a column. The first one is the max number of con‐
400 current sessions for a single login. The second one is the maxi‐
401 mum number of anonoymous sessions.
402 -Y tls behavior
404 -Y 0 (default) disables TLS security mechanisms.
405 -Y 1 Accept both normal sessions and TLS ones.
406 -Y 2 refuses connections that aren't using TLS security mecha‐
407 nisms, including anonymous ones.
408 -Y 3 refuses connections that aren't using TLS security mecha‐
409 nisms, and refuse cleartext data channels as well.
410 The server must have been compiled with TLS support and a valid
411 certificate must be in place to accept encrypted sessions.
412 -z Allow anonymous users to read files and directories starting
414 with a dot ('.').
415 -Z Add safe guards against common customer mistakes (like chmod 0
417 on their own files) .
418
422 Some of the complexities of older servers are left out.
423 This version of pure-ftpd can use PAM for authentication. If you want
425 it to consult any files like /etc/shells or /etc/ftpd/ftpusers consult
426 pam docs. LDAP directories and SQL databases are also supported.
427 Anonymous users are authenticated in any of three ways:
429 1. The user logs in as "ftp" or "anonymous" and there is an account
431 called "ftp" with an existing home directory. This server does not ask
432 anonymous users for an email address or other password.
433 2. The user connects to an IP address which resolves to the name of a
435 directory in /etc/pure-ftpd/pure-ftpd (or a symlink in that directory
436 to a real directory), and there is an account called "ftp" (which does
437 not need to have a valid home directory). See Virtual Servers below.
438 Ftpd does a chroot(2) to the relevant base directory when an anonymous
440 user logs in.
441 Note that ftpd allows remote users to log in as root if the password is
443 known and -u not used.
444
447 If a user's home directory is /path/to/home/./, FTP sessions under that
448 UID will be chroot()ed. In addition, if a users's home directory is
449 /path/to/home/./directory the session will be chroot()ed to
450 /path/to/home and the FTP session will start in 'directory'.
451 As noted above, this pure-ftpd omits several features that are required
453 by the RFC or might be considered useful at first. Here is a list of
454 the most important omissions.
455 On-the-fly tar is not supported, for several reasons. I feel that users
457 who want to get many files should use a special FTP client such as
458 "mirror," which also supports incremental fetch. I don't want to either
459 add several hundred lines of code to create tar files or execute an ex‐
460 ternal tar. Finally, on-the-fly tar distorts log files.
461 On-the-fly compression is left out too. Most files on an FTP site are
463 compressed already, and if a file isn't, there presumably is a reason
464 why. (As for decompression: Don't FTP users waste bandwidth enough
465 without help from on-the-fly decompression?)
466
469 Shortcuts for the "cd" command can be set up if the server has been
470 compiled with the --with-diraliases feature.
471 To enable directory aliases, create a file called /etc/pure-
473 ftpd/pureftpd-dir-aliases and alternate lines of alias names and asso‐
474 ciated directories.
475
478 This server leaves out some of the commands and features that have been
479 used to subvert anonymous FTP servers in the past, but still you have
480 to be a little bit careful in order to support anonymous FTP without
481 risk to the rest of your files.
482 Make ~ftp and all files and directories below this directory owned by
484 some user other than "ftp," and only the .../incoming directory/direc‐
485 tories writable by "ftp." It is probably best if all directories are
486 writable only by a special group such as "ftpadmin" and "ftp" is not a
487 member of this group.
488 If you do not trust the local users, put ~ftp on a separate partition,
490 so local users can't hard-link unapproved files into the anonymous FTP
491 area.
492 Use of the -s option is strongly suggested. (Simply add "-s" to the end
494 of the ftpd line in /etc/inetd.conf to enable it.)
495 Most other FTP servers require that a number of files such as
497 ~ftp/bin/ls exist. This server does not require that any files or di‐
498 rectories within ~/ftp whatsoever exist, and I recommend that all such
499 unnecessary files are removed (for no real reason).
500 It may be worth considering to run the anonymous FTP service as a vir‐
502 tual server, to get automatic logins and to firewall off the FTP ad‐
503 dress/port to which real users can log in.
504 If your server is a public FTP site, you may want to allow only 'ftp'
506 and 'anonymous' users to log in. Use the -e option for this. Real ac‐
507 counts will be ignored and you will get a secure, anonymous-only FTP
508 server.
509
512 The files <ftproot>/.banner and .message are magical.
513 If there is a file called .banner in the root directory of the anony‐
515 mous FTP area, or in the root directory of a virtual host, and it is
516 shorter than 1024 bytes, it is printed upon login. (If the client does
517 not log in explicitly, and an implicit login is triggered by a CWD or
518 CDUP command, the banner is not printed. This is regrettable but hard
519 to avoid.)
520 If there is a file called .message in any directory and it is shorter
522 than 1024 bytes, that file is printed whenever a user enters that di‐
523 rectory using CWD or CDUP.
524
527 You can run several different anonymous FTP servers on one host, by
528 giving the host several IP addresses with different DNS names.
529 Here are the steps needed to create an extra server using an IP alias
531 on linux 2.4.x, called "ftp.example.com" on address 10.11.12.13. on the
532 IP alias eth0.
533 1. Create an "ftp" account if you do not have one. It it best if the
535 account does not have a valid home directory and shell. I prefer to
536 make /dev/null the ftp account's home directory and shell. Ftpd uses
537 this account to set the anonymous users' uid.
538 2. Create a directory as described in Anonymous FTP and make a symlink
540 called /etc/pure-ftpd/pure-ftpd/10.11.12.13 which points to this direc‐
541 tory.
542 3. Make sure your kernel has support for IP aliases.
544 4. Make sure that the following commands are run at boot:
546 /sbin/ifconfig eth0:1 10.11.12.13
548 That should be all. If you have problems, here are some things to try.
550 First, symlink /etc/pure-ftpd/pure-ftpd/127.0.0.1 to some directory and
552 say "ftp localhost". If that doesn't log you in, the problem is with
553 ftpd.
554 If not, "ping -v 10.11.12.13" and/or "ping -v ftp.example.com" from the
556 same host. If this does not work, the problem is with the IP alias.
557 Next, try "ping -v 10.11.12.13" from a host on the local ethernet, and
559 afterwards "/sbin/arp -a". If 10.11.12.13 is listed among the ARP en‐
560 tries with the correct hardware address, the problem is probably with
561 the IP alias. If 10.11.12.13 is listed, but has hardware address
562 0:0:0:0:0:0, then proxy-ARP isn't working.
563 If none of that helps, I'm stumped. Good luck.
565 Warning: If you setup a virtual hosts, normal users will not be able to
567 login via this name, so don't create link/directory in /etc/pure-
568 ftpd/pure-ftpd for your regular hostname.

572 /etc/passwd is used via libc (and PAM is this case), to get the uid and
573 home directory of normal users, the uid and home directory of "ftp" for
574 normal anonymous ftp, and just the uid of "ftp" for virtual ftp hosts.
575 /etc/shadow is used like /etc/passwd if shadow support is enabled.
577 /etc/group is used via libc, to get the group membership of normal
579 users.
580 /proc/net/tcp is used to count existing FTP connections, if the -c or
582 -p options are used
583 /etc/pure-ftpd/pure-ftpd/<ip address> is the base directory for the <ip
585 address> virtual ftp server, or a symbolic link to its base directory.
586 Ftpd does a chroot(2) into this directory when a user logs in to <ip
587 address>, thus symlinks outside this directory will not work.
588 ~ftp is the base directory for "normal" anonymous FTP. Ftpd does a ch‐
590 root(2) into this directory when an anonymous user logs in, thus sym‐
591 links outside this directory will not work.

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