Serv-U Version 7.3.0.1

Serv-U 7.3.0.1 was released June 2, 2008. A complete list of changes and upgrades follows:

• Added the ability to view and download 3 different sized images on the iPhone/iPod Touch (small, medium, and full-sized).
• Changed iPhone/iPod Touch keyboard so that it doesn't start automatically with CAPS on for all input fields.
• Improved "Unable to establish SSL connection" log message when the client simply disconnects during the negotiation phase. This usually indicates that the client has rejected the SSL certificate.
• Improved the Basic Web Client for the iPhone and iPod Touch by disabling the parent directory buttons when in the user's root directory.

• Corrected an iPhone/iPod Touch bug where the "Up Directory" button would not work in the home directory if the user wasn't locked in the home directory.
• Corrected a problem where large HTTP/HTTPS uploads could pause indefinitely. This problem could appear when Serv-U was running on a multi-processor / multiple-core server.
• Corrected a Basic Web Client bug where keyboard focus was not reset to the file list after a delete confirmation dialog was displayed.
• Corrected an FTP display bug when specifying a wildcard character such as "*" or "?" as a parameter for a path name, Serv-U would return the first file with the matching name in its response.
• Corrected an SFTP bug where closing a file handle, and attempting to set the file attributes on a file where permission is denied could cause Serv-U to crash.
• Corrected a bug in FTP Voyager JV where uploading a directory with the same name as the destination would produce an error.
• Corrected a security bug where specifying a Windows port (such as CON:, LPT1:, PRN:, etc.) when using the STOU command, could cause Serv-U to consume all of the CPU time on a processor. This problem could only occur when write privileges were granted to the specified directory. (Secunia SA32150)
• Corrected a security bug with rename where moving a file or directory to a location where delete privileges were not granted for an existing file or directory, would cause the file or directory to be moved. (Secunia SA32150)
• Corrected a security bug with rename where placing the destination in "\" (i.e., "My Computer") would cause the file to moved to the current Windows directory.

Serv-U Version 7.1.0.2

Serv-U 7.1.0.2 was released June 2, 2008. A complete list of changes and upgrades follows:

• Updated OpenSSL libraries from 0.9.8g to 0.9.8h.
• Changed the verification for FTP Voyager JV to show whether the license is a trial, enabled, or disabled depending on the license status.
• Updated Swedish and Italian strings.
• Added icons for ISO files in the Basic Web Client.

• Corrected a user file name bug where using a reserved Windows file name such as "PRN" as the login ID, Serv-U was unable to store the user's archive file.
• Corrected an upgrade bug concerning the way files are opened when downloading. The setting, if not the default, was not being imported.
• Corrected a bug where the check for cookies being enabled was not working correctly when logging in through the tray.
• Corrected a bug where text was allowed to be selected in the Basic Web Client when using FireFox.
• Corrected a rare bug in the Management Console where a script error could occur when viewing the list of groups available for a user to join.
• Corrected a bug when updating from previous versions, the local administrator password may not have been imported when custom certificates were being used.
• Corrected a bug in FTP Voyager JV where dropping files outside of the table's columns would not initiate the transfer to the working directory.
• Corrected a bug in FTP Voyager JV where if a rename of a file failed, the GUI would not refresh itself to show the original file name.
• Corrected a bug in FTP Voyager JV where uploading nested directories would cause the transfer to stop working.
• Corrected a bug in FTP Voyager JV's remote panel where attempting to get thumbnails when there weren't any to retrieve would cause serious errors and unexpected results.
• Corrected a bug where Serv-U wasn't following individual file mask directory access WRITE rules when uploading when LIST for the mask was also disabled. For example, disabling all permissions of "*.exe" using directory access rules, Serv-U would still allow uploading of any .EXE file if the proper parent permissions were set.
• Corrected a problem where directories using the "[" character would not list correctly due to *NIX wildcard comparison support. Support for character set filtering has been removed from Serv-U.
• Corrected a bug where moving users to a different user collection would lock up the Management Console (not Serv-U itself) and the move would fail.
• Corrected a bug where using the enter key to move to the next section in the User Wizard dialog would fail to put focus in the next input field.
• Corrected a bug where changing a user's password type would lock up the Management Console and the dialog could not be closed.
• Corrected a bug where using the drive volume combo box in the browse dialog would cause the select and close buttons to no longer work.

Serv-U Version 7.1.0.0

Serv-U 7.1.0.0 was released May 19, 2008. A complete list of changes and upgrades follows:

• Improved the speed of directory listings in Basic Web Client and browse dialog by 65%.
• Greatly improved the speed at which listings of large amounts of data are displayed, especially large User collections.
• Greatly improved the sorting speed in the Basic Web Client and browse dialog when reversing the sort direction.
• Added the ability to play audio and video files from within the Basic Web Client.
• Added the ability to play all audio files continually from within the Basic Web Client.
• Added UTF-8 file name and path support to FTP. Serv-U supports the "OPTS UTF8 ON|OFF" command to enable or disable UTF-8. By default UTF-8 is enabled for the FTP protocol (RFC 2640), but can be disabled if desired.
• Added support for CSID (Client / Server Identification Exchange) to identify the client to the server, and the response identifies the server to the client. The information exchanged includes the name and version number of the client and server, and information about the server including the operating system, file system letter case sensitivity, operating system version number, and directory separator. This command obsoletes the CLNT command.
• Added the "SITE HELP" and "SITE HELP cmnd" command to support clients, such as Internet Explorer, that make this request.
• Added a new configuration option for NLST, where NLST can be configured to list empty directories instead of returning "550 No file found.", which is more meaningful to FTP clients than returning an error code.
• Added new tags for FTP and HTTP (welcome message) string replacement. The new tags are $ServerName, $OS, and $OSVer.
• Added new tags to the System Variables section of the Help documentation under Additional Reference. The new tags are $ServerName, $OS, and $OSVer.
• Added client identification to the list of active connections for SSH connections.
• Added the ability to disable the server identification for SSH for the entire server or for individual domains.
• Added the ability to disable the use of Windows User (Active Directory / Windows Login) home directory in favor of the group home directory.
• Improved the use of the SSH local "Window Size" to improve SFTP performance, especially for uploads.
• Changed the default NLST operation to list empty directories instead of returning an error code; "550 No file found.". Upgrades from Serv-U 6.4 and earlier will still return the error code unless changed manually.
• Changed the default open file mode for downloads to "Full Access" like in previous versions of Serv-U.
• Changed the installer to convert Serv-U 6.4 and previous to also keep the open file mode for download.
• Changed Virtual Paths' physical path to allow the use of %HOME% and %USER% in the physical path in addition to in the virtual path fields.
• Changed the XCRC FTP command to accept parameters even when the file name isn't wrapped with quotation marks.
• When Windows shortcut files (.LNK files) are encountered, and the target no longer exists or cannot be found, Serv-U treats the shortcut like any other file.
• Updated Swedish and Japanese tray strings.
• Removed the "Windows Authentication" tab from the server global user settings, as it was non-functional. Windows authentication may be enabled only on a domain-by-domain basis.
• Slide Show mode for the Basic Web Client now navigates images according to the current sorting arrangement.
• Increased the size of the Address column in the IP access rules list.
• Added the removal of files that are not found when performing a delete, copy, or rename operation in FTP Voyager JV.
• Added better status information to the delete and copy dialogs of FTP Voyager JV. It now shows the files inside a directory that is currently being processed.
• Improved responsiveness of user interaction by reducing the load on the worker threads of FTP Voyager JV.
• Improved FTP Voyager JV's transfer speed by using buffers with dynamic sizes.
• Added a password change confirmation dialog to FTP Voyager JV that shows if the operation was successful.
• Appended an index counter that is shown in FTP Voyager JV's "Name" column of the transfer panel.
• Decreased the size of the FTP Voyager JV download file by about 85 KB.
• Removed the email address field from certificate creation dialog as it is not accepted by many certificate authorities.
• Added the ability to launch FTP Voyager JV from the Basic Web Client.
• Changed the client selection dialog to use radio buttons instead of a drop down combobox.
• Added the ability to go back to the Basic Web Client from the FTP Voyager JV launch page.

• Corrected a problem where long path names would cause the logout button to be hidden in the Basic Web Client.
• Corrected a problem with the certificate requests generated by Serv-U that caused Certificate Authorities to reject the CSR file as invalid. The CSR files generated by Serv-U have been successfully tested and signed using Thawte and GeoTrust.
• Corrected a problem on some systems, usually upgrades from previous versions, where the Management Console could prompt for a password even when one isn't defined for administering Serv-U.
• Corrected a bug where delete privileges were not required to overwrite an existing file. This change is designed to maintain compatibility with previous versions of Serv-U.
• Corrected a bug where append privileges were not required when resuming transfers with the REST FTP command. This change is designed to maintain compatibility with previous versions of Serv-U.
• Corrected a bug where the AVBL and DSIZ commands would return an invalid value when attempting to list the non-existent "\" directory (i.e., all drives).
• Corrected a bug where an FTP active data socket that was supposed to bind on 127.0.0.1 (localhost) Serv-U wouldn't bind to that IP address only.
• Corrected a bug when attempting to rename a drive, Serv-U would not return with an error code.
• Corrected a bug where issuing PASV then ALLO instead of immediately trying to transfer a file, the ALLO command (or any non-transfer threaded command) could fail due to a misinterpretation of an internal result code.
• Corrected a bug in the XCRC FTP command where sending "XCRC file.fid", then "XCRC file.fid 0 100" would generate the same result even though the second command checks only part of the file, not the entire file.
• Corrected a bug in the log where the log would show a blank user name when a user not requiring a password would login.
• Corrected an HTTP / HTTPS login bug with Windows Authentication, where the login could appear to hang with the "Loading" dialog.
• Corrected an HTTP / HTTPS login bug with Windows Authentication, where the welcome message may not be displayed correctly.
• Corrected improper usage of and punctuation concerning "i.e." and "e.g." in the Management Console and Basic Web Client Help documentation.
• Corrected a problem where the bubble tip dimensions in the management console were not calculated correctly when long title names were used.
• Corrected a bug where the update notification dialog / balloon tip would appear every 2 hours if an update was available. This notification now only appears every 3 days, as was originally intended.
• Corrected an FTP data socket bug where Serv-U was not recognizing a data socket was closed, and would not allow another data socket on that IP address and port. This problem showed when attempting to do server-to-server (FXP) transfers.
• Corrected a potential GPF (crash) bug when shutting down Serv-U after clients have connected, using FTP, and changed hosts via the HOST command, to the non-primary domain on the IP address.
• Corrected an SFTP (SSH) bug with the SSH_FXP_FSTAT command where Serv-U would always return SSH_FX_NO_SUCH_FILE.
• Corrected an SFTP (SSH) bug when setting the file attributes, Serv-U was using the "world" bits instead of the "owner" bits for read, write, and execute.
• Corrected an SFTP version 3 (SSH) bug where Serv-U was not setting the permissions attribute of the SFTP file attribute to S_IFREG for files, stopping some SFTP clients from being able to download files.
• Corrected an SFTP (SSH) bug where Serv-U could pause when uploading or downloading files using the *NIX SFTP client.
• Corrected an SFTP (SSH) bug where Serv-U could crash (GPF) when a session timed out due to inactivity.
• Corrected an SFTP (SSH) logging bug where an invalid session number (18446744073709551615) would be logged for some transactions.
• Corrected an SSH problem where Serv-U was not properly handling the SSH remote "Window Size" established by the client.
• Corrected an SSH protocol problem where Serv-U could crash (GPF) when compression wasn't being used, and the client sent an invalid packet size.
• Corrected broken links to additional command information in the FTP Settings dialog where the command consisted of multiple words, e.g., SITE HELP.
• Corrected a bug where Serv-U could crash (GPF) when automatically blocking an IP address for a domain based on invalid login attempts.
• Corrected an ODBC problem with MS SQL 2005 where the database returns failure when data doesn't exist. Serv-U was attempting to reconnect to the database assuming it had timed out, but it hadn't. Now Serv-U uses a built-in 5 minute timeout before attempting to reconnect to the database upon errors.
• Corrected an ODBC problem with MS SQL 2005 where the database would return an error regarding "Connection is busy with results for another hstmt".
• Corrected a Basic Web Client bug where the Slide Show could show a placeholder image for the first image if no file is currently selected or the currently selected file is not an image.
• Corrected a Basic Web Client upload dialog width problem where German text would cause the upload path field to scroll.
• Corrected a bug where non-default database column map values displayed HTML bold tags surrounding the value when they were edited.
• Corrected a bug where changes to the maximum directory size of a Directory Access rule were not saved if the Enter key was used to save the changes when the keyboard focus was still in the maximum directory size input field.
• Corrected a bug where the right-click context menus were not shown for the FTP command and Limits lists for the Server and Domain.
• Corrected a bug where the limits list did not sort correctly.
• Removed a redundant confirmation dialog from FTP Voyager JV when deleting server-side read-only files. By default, Serv-U does not allow this operation. Therefore, you will receive a "Permission Denied" failure.
• Corrected the height of the View Certificate dialog that caused it to be capable of being dragged partially out of view from within the Management Console.
• Corrected a duplicate FTP response in the Global FTP Properties response codes, for paths that are ports.
• Shortened a partially obscured German string on the Universal Plug-and-Play device configuration screen displayed during installation.

Serv-U Version 7.0.0.4

Serv-U 7.0.0.4 was released April 23, 2008. A complete list of changes and upgrades follows:

• Corrected an FTP bug with STOR, STOU, and APPE when specifying the destination file path with back slashes instead of forward slashes, and the destination file doesn't already exist, Serv-U would place the file in the user's home directory instead of the requested directory.
• Corrected insertion of erroneous text at the beginning of each page of the Japanese Help documentation for FTP Voyager JV.
• Corrected a bug where Japanese Help documentation was sometimes displayed using an incorrect charset.
• Corrected a bug introduced in 7.0.0.3 where opening the Help documentation from the FTP Voyager JV launch page reset the current display language.
• Corrected a bug where auto login failed when auto selecting a language.

Serv-U Version 7.0.0.2

Serv-U 7.0.0.2 was released April 9, 2008. A complete list of changes and upgrades follows:

• Updated Traditional and Simplified Chinese license files.
• Updated Japanese Management Console strings.
• Reduced the size of several translated license files.
• Updated Swedish translation and added as an installation option.
• Changed the VARCHAR definitions from 512 to 255 for database creation so Microsoft Excel and Microsoft Access can be used as a database for Serv-U.

• Corrected a bug where Serv-U would allow certain operations in the computer root ("\") instead of on a UNC path or drive path. The computer root is not a physical entity that can be written to or read from. Because of this operations must be denied.
• Corrected a bug where the copyright text on the Server Details page under the Program Information tab was being wrapped incorrectly.
• Corrected an ODBC bug where the SQL statement used to add columns to an existing table did not work for MS SQL 2000.
• Corrected an ODBC bug where if the columns of data were requested "out of order" (according to the column ordinal) MS SQL 2000 would fail.
• Corrected a problem with old Serv-U Corporate registration IDs.
• Changed how anonymous FTP login works when anonymous login is not allowed. As with previous versions of Serv-U, when "USER anonymous" is received, it is accepted, until the "PASS xxxx" command is received, when the anonymous login is rejected. This change is due to Windows Explorer and Internet Explorer, rejecting the user after the USER command causes the login to fail, and not prompt for a user ID and password.
• Corrected a bug where Windows shortcuts to drives would cause a GPF (crash) if Serv-U is treating Windows shortcuts as the target.
• Changed the default ASCII / BINARY transfer mode (which is only cosmetic in Serv-U) to ASCII as with versions prior to 7.0.0.1.
• Corrected a problem where the TYPE FTP command was not supporting the "REPRESENTATION TYPE (TYPE)" format as outlined in RFC 765.
• Corrected a bug in FTP Voyager JV where SSL uploads would insert an HTTP protocol header into the uploaded file. This also improves the transfer speed.
• Corrected a bug in FTP Voyager JV where the Help button of the About dialog was broken.

Serv-U Version 7.0.0.1

Serv-U 7.0.0.1 was released April 2, 2008. A complete list of changes and upgrades follows:

• Added support for the HTTP protocol with a built-in web client.
• Added support for the SSH protocol.
• Added support for FTP Voyager JV via the HTTP protocol.
• Added the THMB command to convert graphical files to thumbnails then download. The THMB command acts exactly like RETR, except prior to transfer the file is reduced to the specified format and maximum size.
• Added the HOST command which allows the FTP client to change to a specific domain on the server. This allows the FTP server to support multiple domains on a single IP address and port. NOTE: not all FTP clients support this feature. FTP Voyager, for example, does.
• Added the DSIZ command to return the size of a directory's contents, including sub-directories. A directory may be specified, or if left blank, the current working directory is used.
• Added the AVBL command to return the number of bytes available in a directory. A directory may be specified, or if left blank, the current working directory is used.
• Added support to enable and disable specific FTP commands.
• Added support to change nearly any FTP command responses.
• Added dynamic HELP information where HELP sends all supported and enabled commands.
• Added command level HELP. For example "HELP LIST" returns help specifically about the LIST command
• Added the use of a floating buffer size when reading from files being downloaded by a client. The floating buffer size is based on the transfer rate for the ongoing transfer, making transfers much more efficient.
• Added directory rename rights setting.
• Added file rename rights setting.
• Added the "\" path concept. The "\" path is similar to "My Computer" in Windows Explorer. When a user's home directory is set to "\" a listing of "/" shows the available disk drives. Users who are not logged in their home directory can also take advantage of this feature when the "Allow root ("/") to list drives for unlocked users" is set to true at the user, group, domain or server levels.
• Changed FEAT to list special commands only when they're enabled.
• Changed the "OPTS MLST" command to be more forgiving of clients that don't follow the RFC exactly. For example, Serv-U now accepts both "OPTS MLST Type;Size;Modify;Perm;" and "OPTS MLST Type;Size;Modify;Perm"
• Added the "Perm" feature for MLST and MLSD commands, "Perm" identifies permissions for an item in an MLST/MLSD listing, relative to the connected user.
• Added the "Win32.dt" feature for MLST and MLSD commands, "Win32.dt" identifies a drive type for disk drive listings, when listing /C:/, /D:/, or /. This feature will not be returned in a directory listing if the item is not a disk drive.
• Added the "Win32.dl" feature for MLST and MLSD commands, "Win32.dl" identifies a drive label for disk drive listings, when listing /C:/, /D:/, or /. This feature will not be returned in a directory listing if the item is not a disk drive.
• Added more information to the MLST / MSLD Type fact for "os.UNIX=slink" where Serv-U now also appends ":linked_path" if this information is available to the user.
• Improved Windows Shortcut resolution to also include shortcuts using relative paths and other combinations of attributes.
• Added the ability to specify path names with spaces when using the "SITE EXEC" command. If spaces are required, Serv-U parses the file name in quotes.
• Added the XDEL command, same as DELE.
• Added RMDA directory as a superset of RMD, allowing the client to delete a directory an all of its files and sub-directories in one command. An error response indicates that the client should refresh its directory listing to determine which files and sub-directories were deleted and which where not.
• Changed Windows Link support so that when Windows .LNK files are encountered they are treated as the file they reference when listing, for the SIZE command, and transfer operations.
• Removed the -L LIST and NLST option because it can conflict with other settings.
• Perform all lengthy commands in a worker thread, freeing up the main thread to service other clients. These operations include LIST, NLST, MLST, MLSD, RMDA, RETR, THMB, RNTO, XCRC, STOR, APPE, STOU, SITE EXEC, and all other lengthy operations.
• Added the use of multiple CPUs to perform CPU intensive activity.
• Added transfer totals and transfer rates to the "226 Transfer complete." reply.
• Added compression totals, statistics, and transfer rates to the compressed "226 Transfer complete." reply.
• Added the ability to define anti-hammer limits for the domain in addition to at the server.
• Increased the maximum string length in a message file from 195 characters to 512 characters.
• Added an option to include server response values to the FTP command processor to include the numeric response code in every line of a multi-line response.
• Added an option to include server response values for individual message files.
• Moved message file settings with the appropriate FTP command and to individual command processors.
• Added the ability to set maximum file sizes for files of certain types, based on the file extension. This feature is implemented through directory access rules where wild cards can be used to identify file access rights.
• Added maximum directory size restrictions for directories specified in the directory access rules, replacing disk quotas.
• Added upload and download bandwidth limits for the entire server, each domain, each group, and each user, in addition to session bandwidth limits.
• Added additional statistics to the STAT command.
• Improved the ALLO command to check the amount of disk space available to the user, instead of just the hard drive space available. This change takes into consideration quotas and directory size limits.
• Added the ability to show directory listings in Microsoft IIS FTP Server (-h:IIS) format or DOS (-h:DOS) (command line from Windows 2000 or greater) format with the FTP LIST command.
• Added -h:"DOS", -h:"IIS", and -h:"UNIX" (default) LIST directives. -h:"DOS" lists files and directories similar to the Windows command line. -h:"IIS" lists files and directories similar to Microsoft's IIS FTP server. -h:"UNIX" lists files and directories similar to BSD UNIX FTP servers. Any other -h"xxx" directive reverts back to "UNIX" style listings. This directive is not letter case sensitive.
• Changed the operation of IP access rules. If there are no "allow access" rules, "*.*.*.*" is automatically assumed
• Added the ability to see blocked IP addresses in the IP access rules list when disconnecting a user from the active session list.
• When uploading and overwriting a file, the original file is renamed to the specified file name.
• Changed directory listings not to show "." and ".." when the user is locked in the home directory.
• In directory listings that show "." and ".." normally, these are properly shown whether or not they exist in Windows. This helps to aid both in navigation and in preventing the user from being able to determine if a directory is a root virtual path or not.
• Added the ability to see passwords in the logs on failure, and with FTP commands.
• Added categorization for users to help organize users into logical groupings. When users are placed into separate categories the Management Console can perform more efficiently as can Serv-U.
• Access to virtual paths can now be granted by allowing access to the physical path only. Previous versions required an explicit access setting to the virtual path as well.

• Corrected an error when exceeding the maximum number of login attempts after being logged in at least once, where Serv-U would return two error replies instead of one.
• Corrected an error where certain LIST and NLST parameters did not work correctly, for example -I:"*.txt" to ignore certain files.
• Corrected an error in MLST/MLSD where Serv-U could return file times 1 hour incorrectly when the server is currently running in Daylight Saving Time and the file date and time is not and vice versa.
• Corrected a bug where "Sub-directory Inherit" was ignored when a full path is specified containing a wildcard string. For example C:\Windows\*.jpg would not include C:\Windows\System32\*.jpg even when the inherit flag was selected.
• Corrected a bug where recursively listing directories where Virtual Paths referenced the parent directory, would cause Serv-U to crash.
• Corrected a bug when using "blind" directories, where directory access to directories nested at least two deep have access, it was possible for sessions to never be able to go back to the home directory with the CWD command.

• Added new style menus.
• Added the ability use different themes.
• Added Theme Editor.
• Added balloon tips.
• Added automatic update checker.
• Added support links to pop-up menu.
• Added more statistics to the mouse over tool tips.
