Changes ======= Version 1.125 ------------- Thu Nov 29 08:10:47 UTC 2012 IMPROVEMENTS: * supported cpantesters and added other small changes. (thanks to Alexandr Ciornii) * tweaked t/240abort.t to skip when BSD::Resource is not installed to avoid test errors on OpenBSD/Solaris at cpantesters. * improved an error message when using chroot feature by non-root users with Full personality. Version 1.124 ------------- Thu Nov 22 13:26:09 UTC 2012 IMPROVEMENTS: * addressed an issue that ftpd.conf had been installed despite lack of write permission to sysconfdir. [#81130] (thanks to Gabor Szabo) * added a message that Win32 platform is not supported. [#81136] (thanks to CHORNY) * switched to Test::More for better installation process. Version 1.123 ------------- Tue Nov 13 03:08:08 UTC 2012 Maintenance release after a long time BUG FIXES: * added a workaround to make sure to cause abort by SIGURG in t/240abort.t. [#21261] * fixed a bug that MLST command treated DirHandle as FileHandle. [#27640] (thanks to Andrew) * fixed a bug that ls -l command doesn't show a directory named '0'. [#29503] * fixed a problem that extra large file sizes were not displayed correctly because of integer digit overflow. [#35332] (thanks to Kevin Morga) * fixed a problem caused by a Constant.pm internal change, affected to Archive::Zip. [#35698] (thanks to Alexander Bluhm) * fixed a problem that Archive::Zip::Member::setLastModFileDateTimeFromUnix() doesn't accept 0. [#35698] (thanks to Alexander Bluhm) OTHERS: * maintainer now changed. * organized document and package files. * fixed pod format errors. * new repository: https://github.com/ryochin/p5-net-ftpserver Version 1.122 ------------- (No description) Version 1.121 ------------- (No description) Version 1.120 ------------- Added PREREQ_PM to Makefile.PL so CPAN works (thanks to barbie at missbarbell dot co dot uk). Fixed a few warnings (thanks David Wheeler, david at kineticode dot com). Version 1.119 ------------- Added FTP proxy backend (highly experimental - please test). Patch from John Jetmore to open /etc/localtime in chroot environment. All of the following from Yair Lenga: 'rotate log files' configuration. open_data_connection fix for non-reusable sockets on SunOS. 'die' replaced with 'confess' in a few places to aid debugging. Allow 'ftp data port' to be given as a service name, as well as a number. 'authentication_hook' may return -2 to avoid sleep. Don't drop priviledges if 'ftp data port' is bound to a socket < 1024. Send back GMT in MDTM command. Various extra directives such as '%Y' can be included in log file names (undocumented?). Version 1.118 ------------- Moved to Savannah.nongnu.org. Version 1.117 ------------- Fix t/350filters.t uudecode syntax to comply with certain systems. Version 1.116 ------------- Incorporated a change from the FreeBSD port of Net::FTPServer - does not install with '-g root' (which is a Linux-ism). Thanks for petef at freebsd.org for the patch. Less strict regex for PORT command (spot by Brian.Freeman at eby-brown.com). Allow "make test" to pass when certain filter commands are missing. Fix t/350filters.t compress syntax to comply with certain systems (spot by Vicki Brown vlb at cfcl.com). Allow name based port to be used for source port on the server endpoint for PORT mode transfers. (i.e., "ftp data port: ftp-data" works now. This is required by some router/firewall configurations. - Rob Brown) Compatibility fixes for ExtUtils::MakeMaker (5.91, 6.03, 6.10_03). Other minor package/build/make/rpm/install changes. Version 1.115 ------------- Remove bootstrap code from spec file so rpm works again. (Broken since 1.112.) Add "ftp data port" directive to allow server to comply closer with RFC 959 if the user wishes to do so. But for security reasons, the default remains to use the high ephemeral port. -- Rob Version 1.114 ------------- No new features. Bug fixes only. Fix t/150commands.t LANG test failure on some systems. Avoid race condition in t/400sighup.t that can occur when client connects before SIGHUP is done restarting the server. Fixed the RMD bug introduced from Luis' Darwin / Mac OS X "removing directoring" patch in 1.112. Now RMD works again for the "Full" personality. -- Rob Version 1.113 ------------- Removed all XS code. Signal handlers are pure perl now even for older versions of perl < 5.7. Concept taken from Net::Server::SIG in order to avoid dangerous pitfalls of unsafe signal handling in older versions of perl. -- Rob Version 1.112 ------------- Avoids sleeping in Makefile.PL if you set NET_FTPSERVER_NO_SLEEP=1. If Perl version >= 5.7.2, then the XS-based safe signals code is disabled. These later Perl versions include safe signals, so it is not needed. Note to package maintainers: if using Perl >= 5.7.2, then Net::FTPServer is pure Perl code, no C. Allow non-alpha characters in SITE commands (feature requested by Brian Freeman). Luis Mun\~oz fixed a problem with removing directories on Darwin / Mac OS X. Luis also added the 'chdir rule' which allows finer control over what directories a user may change into. Allow the build to work if there is a different version of the server installed. Changes by Rob Brown: 1) Reduce redundant code. 2) Allow easier overrides for Full and RO personalities. (That whole "sub list" doesn't need to be copied.) 3) Avoid spewing warnings to the logs and showing garbage to the client for a race condition where the node has been removed between the time of the IO::Dir read and the time of the @array stashing. Version 1.111 ------------- Fixed a critical memory corruption error. Fixed and removed a faulty call to 'fcntl' which passed a parameter by value where a pointer was expected. (One symptom was that messages produced by the '-d' option in the system log could appear blank). Work around a bug in Perl 5.6.0 which was causing the SYST command (and possibly other commands) to fail at random because a regular expression match gave $1 a corrupted value. Version 1.110 ------------- Workaround for a bug in IE 6.2600.0000. This version of IE sends a leading 0 before the IP address in the PORT command (eg. PORT 0212,57,32,3,1,2). Version 1.109 ------------- Tested the FTP server on Perl 5.00405, so changed the Makefile.PL to allow this version. (Note on this version of Perl there are various warnings caused by bugs in Perl itself -- ignore them). Version 1.108 ------------- Tests will now succeed even if certain optional packages are not installed, such as for example Archive::Zip and the "compress" command. Version 1.107 ------------- Last release was broken: I forgot to change the MANIFEST file. This release corrects that mistake. Version 1.106 ------------- Added a "debian/" directory. Version 1.105 ------------- The "Full" backend now has an additional option ("password file") to allow authentication against a flat password file instead of the normal PAM database. Documentation updates for Debian. Version 1.104 ------------- Security fix: NLST honours the "list rule" access control rule (thanks to Jamie Hill <<email@example.com>). Removed a warning generated by calling getprotobyname. Don't overwrite the old configuration file. Added a "readlink" function to file-based file handles so that symbolic links can be displayed correctly. Version 1.103 ------------- Documentation updates (azazel). Install start-up scripts and ftpd.conf file automatically. Multiple fixes to RPM spec file. Additional roadmap docs. Version 1.102 ------------- Better handling of CPAN version numbers in subclasses. Load Digest::MD5 early so it works with chroot (thanks Peter Gordon for pointing out the bug). Added quit_hook (for Bjn Groﾟmann). Don't hard-code path to Perl interpreter in the scripts. Added roadmap. Added "class" directive. Advanced command filtering ("restrict command" directives). Ordinary and advanced command filtering no longer log you out. They just send back an error message. Allow limits to be set to -1 to indicate no limit. Version 1.101 ------------- post_command_hook now gets the command as an argument. Removed can_* functions from backends. In ASCII mode, downloading a file ending in "\n0" would cause corruption: now fixed. Version 1.100 ------------- Various small bugs fixed by Rob. Fixed a bug in Full/RO personalities which would cause incorrectly formatted directory handles to be created in some circumstances. Doubled memory and process limits so that default install will work correctly on Alpha. Added archive mode: try downloading "file.gz" (gzipped version of "file" will be created on the fly); try downloading "dir.list.gz" (compressed directory listing will be created on the fly); lots of other novel and interesting uses of this feature: see section ARCHIVE MODE in manual. Documentation updates. More tests. Added "visit" member for recursing over directories. Version 1.031 ------------- Added missed tests to MANIFEST file. Added 'make check-manifest' rule to try to eliminate missing files in the future. Document that %C does not work inside welcome text or welcome file options. Added many more tests (there are now over 400 in all). Fixed anonymous login test. Version 1.030 ------------- Cleaned up server start of day messages. Fixed a nasty bug which prevented command line options from working some of the time (the bug was introduced in the last release). Workaround to keep /etc/protocols open across chroot (thanks to Abraham Ingersoll <firstname.lastname@example.org>). Handle QUIT and client termination the same way so there is a simpler exit path from a child process. Added more tests. Fixed handling of multiple line configuration file keys. Added <IncludeWildcard> directive for configuration files. Version 1.029 ------------- Solaris missing RLIMIT_NPROC fixed (?). Further fixes for Perl 5.7.2: no longer opens /dev/null twice by accident. Cleaned up the way that command line arguments are handled and added the "-o" option which allows you to override configuration file values on the command line. "--help" information enhanced. Documentation updates. Version 1.028 ------------- Change directory to root ("/") when in daemon mode [Rob]. Various fixes and workarounds for Perl 5.7 [Rich]. Various changes to RPM spec file so that it works cleanly under all versions of Perl [dan at berrange dot com]. It has been reported to me that this version does not work on Solaris because of a seemingly minor bug (RLIMIT_NPROC is missing). Unfortunately I don't have a suitable box to reproduce this on. Can anyone help with a patch please? Version 1.027 ------------- VFS only required to support relative forward seeks to simplify certain backends (thanks to Keith Turner for this patch). Version 1.026 ------------- New optional hook: system_error_hook added to allow backends to provide more error information than is provided by the normal "$!" (thanks to Keith Turner for this patch). Various changes to error log (SIGHUP now functions correctly for non-privileged backends) [Rob]. Allow error log to contain variable hostname [Rob]. Safer untainting for log filenames [Rob]. Re-add DAEMON message logging code [Rob]. SIGTERM is handled safely and synchronously [Rob]. Version 1.025 ------------- Changed version numbering system slightly from 1.0.25 to 1.025 to allow version numbers to be compared [Rob]. Optimizations to safe signals code. Version 1.0.24 -------------- Added SITE SYNC command (needs optional File::Sync package from CPAN). Implemented safe signals (see doc/safesignals.txt). Version 1.0.23 -------------- In Full personality, load Authen::PAM before forking. Removed some race conditions involving allocating and deallocating memory in signal handlers. Removed a race condition where a file or directory is removed before being ``stat''ed. Tested under load with 1-128 clients. Added ``error log'' configuration option. Version 1.0.22 -------------- Check for most recent version of IO-stringy installed before proceeding. Added xfer logging (Rob). Don't try to allocate or deallocate memory in SIGCHLD handler -- this was causing the parent process to crash under heavy load (Rob). Better way to avoid warning from loading Sys::Syslog (Rob). Better conditional loading of BSD::Resource (Rob). If using PAM, upgrade to version 0.12 from CPAN (Rich). Rob has reported that this version is now stable again under heavy load. If you have problems, please mail them to: email@example.com. Version 1.0.21 -------------- More documentation on <Perl>. Allow array assignments to %config/%host_config elements. Always check the return value from "close". Replace "lstat" with "stat" (better handling of symbolic links, hopefully). Packages Authen::PAM, BSD::Resource and Digest::MD5 are now truly optional. If you have not installed these packages, the server should still work (albeit with limited functionality) and should warn you when it needs to do something which requires an external package. Corrected pod2man warnings about command line options not being enclosed in C<> or B<>. Version 1.0.19 -------------- Ignore SIGCHLD in child processes (thanks to Duane Powell for finding this bug). The code which parses the configuration file is more strict about illegal constructs such as using <Include> inside a <Host> section. You can use <Perl> sections to insert verbatim Perl code into your configuration files, just like with Apache. Version 1.0.18 -------------- Linux Magazine has an article about Net::FTPServer here: http://www.linux-mag.com/2001-05/toc.html . Avoid storing children hash within the child process to save memory. A better way to remove warnings printed when "syslog.ph" is loaded. Version 1.0.17 -------------- Replaced local function ``syslog'' with ``log'', since it clashes with certain versions of the ``Sys::Syslog'' module which try to import their own ``syslog'' function even if you tell them not to. Fixed dependencies in RPM spec file. Version 1.0.16 -------------- ``max clients'' configuration option allows you to limit the number of clients who may simultaneously connect [Rob]. You can also use ``%x'' in messages to refer to the maximum number of clients. ``hide passwords in client log'' configuration option: if set, don't log PASS commands in the client log [Rich]. ``rename rule'' allows fine-grained control of renaming files [Rob]. Fixed SIZE on a non-readable ASCII (TYPE A) file [Rob]. Fixed ``zero node'' bug (previously it was impossible to create a file or directory called ``0'') [Rob]. Fixed a small bug with the ``list rule'' directive [Rob]. Fixed a problem with various places where using ``/'' as an argument would cause crash [Rob]. Remove HTMLLIBPODS rule in the Makefile [Rich]. The website is no more: the software will always be released first and only to CPAN from now on. To get notification of releases, please subscribe to the ftpserver mailing list. Version 1.0.15 -------------- Several patches from Rob which fix some warnings and bugs which would crash the server child process when a user did MKD / and other similarly bizarre commands. Also, MLST / now works. Common wildcard to regex and wildcard to SQL LIKE functions moved to parent class. Version 1.0.14 -------------- Documentation for /etc/ftpd.conf options moved into the manual page. This aids maintenance considerably. Version 1.0.12 -------------- This contains a small featurette suggested by Rob. You can now disable syslogging from the configuration file. During the automatic tests (make test), syslogging is now disabled by default. Version 1.0.11 -------------- If getpwuid or getgrgid cannot resolve a user ID / group ID into a username or group name, then we print "-" instead, rather than generating an annoying warning message. Thanks go to Elliot Finley and Matthias Ivers who both spotted the bug at about the same time! Version 1.0.10 -------------- Several patches from Rob which fix warnings and a bug which would crash the server child process when a user did SIZE . and similar. Version 1.0.9 ------------- Patch from Rob: ls -al, issued from the Windows command line FTP client, now gives a pretty listing. This also worksaround a number of other clients which like to issue (incorrect) commands like: NLST -al. Version 1.0.8 ------------- Don't use /etc/group directly -- use getgrent instead. Version 1.0.7 ------------- Keep /etc/group open across chroot. Version 1.0.6 ------------- initgroups fixed by Rich (thanks to Matthew Gabeler-Lee for pointing out the problem). Small changes to logging usernames by Rob. Version 1.0.4 ------------- A small patch from Rob Brown which avoids the server leaving zombie processes lying around in some situations. Version 1.0.3 ------------- This version contains patches to make the full server work correctly on OpenBSD. (Thanks to Azazel). Version 1.0.2 ------------- This contains some necessary bugfixes over the 1.0.0 and 1.0.1 releases. Patch to this version if you had problems with those releases. (Thanks to Rob Brown for these fixes). Version 1.0.1 ------------- I've done next to nothing for this release, but Rob Brown has been at it again, producing a beautiful series of bug fixes and enhancements. In no particular order: Avoid hard coded "." and ".." entries in directories. Logging is taint-clean in Perl 5.005. Don't log out-of-band data into client log. Added ident (RFC 1413) logging for increased security. Added "time zone" configuration file option so that dates and times can appear in zones other than GMT. Allow parent daemon to be restarted cleanly even if there are child daemons still left over from the previous process. Sending SIGHUP causes the parent process to cleanly restart, reload configuration files and reopen client logging file (this even works if the daemon has bound to a low-numbered port and dropped priviledges). Version 1.0.0 ------------- Fixed for this release by Rich: STOU now works. Listing files by wildcard now works in the "in memory" personality. Added STOR/STOU/APPE tests. Added LIST/NLST tests. Added SITE IDLE test. Added SITE VERSION test. Added REST test. Added RNFR/RNTO test. Added ABOR test. Added "no authentication commands" configuration option. Fixed for this release by Rob Brown: "Client logging" feature. Distinguish between sending TERM to the daemonized process and to the child processes. Implement ABOR-ted transfers using SIGURG. Added post_bind_hook. DoS attack avoided by reseting the alarm after read and before write. Abort if configuration file is missing. Added transfer_hook. Version 0.9.9 ------------- This fixes a nasty bug with uploading ASCII files. Also added: A fairly complete test suite [Rich]. A cute "in memory" personality [Rich]. Catch errors on ASCII STOR (upload) and report to the client [Rob Brown]. Eliminate the idle transfer DoS bug [Rob Brown]. Never reset the ALRM catcher to inifinity (alarm 0) [Rob Brown]. Pull all clients that are idle even mid-transfer [Rob Brown]. Avoid timing out clients that are actively transfering [Rob Brown]. Missing files added to the MANIFEST [Rich]. Version 0.9.8 ------------- In no particular order: Port numbers opened by the FTP server in passive mode can be configured in ranges from the configuration file (this should improve things if you run a firewall in front of your server). Removed extra spaces in "Entering Passive Mode" string. Code tidying. Add "print" method to IO::Blob - you can now upload ASCII files to the database. In STOR, error messages actually reflect error conditions. Fixed calls to syswrite(). Incomplete three-way TCP handshake no longer crashes the server. Add -P option on the command line to supply name of pidfile. Delete pidfile when main process dies. (Thanks to Rob Brown for the bulk of these fixes). Version 0.9.6 ------------- Fixed a bug with LISTing files in subdirectories (thanks to all @about-inc.com). Version 0.9.5 ------------- I fixed a raft of portability problems on Solaris 2.7. However, there remains a problem that the Perl version I have on Solaris doesn't call initgroups(3) correctly when the process GID is changed, and hence doesn't drop privileges properly. This is beyond my experience to fix -- seemingly requiring deep changes to Perl itself? It also works OK on Linux and *BSD, and that's all that really concerns me anyway. Version 0.9.4 ------------- Fixed a few problems with older versions of PostgreSQL (versions <= 6.3). Version 0.9.3 ------------- Fixed compatibility problems with ncftp versions 2.4.3 and 3.0.2. Mostly fixed MLST/MLSD commands. Added --help option. Fixed -V option. Version 0.9.2 ------------- Bug fixes and clean ups. Version 0.9.1 ------------- Many documentation updates. Added easily customizable SITE commands. Version 0.9.0 ------------- Added a anonymous read-only FTP personality. With this personality, the FTP server contains no code which could be used to write, create directories, delete files, etc. The FTP server will also only accept anonymous logins, and contains no code for checking /etc/passwd or PAM. This is a candidate for a 1.0.0 release. Please download it, play with it, and send me your feedback. Version 0.8.4 ------------- Added the missing database schema. Version 0.8.3 ------------- This version has a fairly complete example database back-end for those that wanted to see that. Version 0.8.0 ------------- This is a highly experimental release which adds a partially implemented database back-end. This is just for people interested in database back-ends to the FTP server. Version 0.7.2 ------------- This fixes a problem when the FTP server is run from inetd (thanks again to Matthew Gabeler-Lee). Version 0.7.1 ------------- This is a stable, high quality release. Several important bug fixes, including an important fix to access control rules (thanks to Matthew Gabeler-Lee for pointing this one out). Version 0.6.1 ------------- This release is highly experimental, but I did all of 5 minutes of testing and it appeared to work for me. Changes: bug fixes and enhancements too numerous to mention. Major change: separated out the file access back-end to improve security (our database version now no longer contains redundant file access code). Included a few more documents. Version 0.5.1 ------------- This fixes a problem in Makefile.PL which prevented the program from building on some platforms. Version 0.5.0 ------------- This major release incorporates support for both IP-based and IP-less virtual hosting. Version 0.4.5 ------------- This version contains a few modifications for submission to CPAN. Version 0.4.4 ------------- First public release.
