Serv-U FTP服务器 <开发商:Rhino Software Inc>

产品简介

FTP的全称是File Transfer Protocol(文件传输协议)。顾名思义，就是专门用来传输文件的协议。而FTP服务器，则是在互联网上提供存储空间的计算机，它们依照FTP协议提供服务。当它们运行时，用户就可以连接到服务器上下载文件，也可以将自己的文件上传到FTP服务器中。

Serv-U是一种被广泛运用的FTP服务器端软件，支持3x/9x/ME/NT/2K等全Windows系列。可以设定多个FTP服务器、限定登录用户的权限、登录主目录及空间大小等，功能非常完备。 它具有非常完备的安全特性，支持SSl FTP传输，支持在多个Serv-U和FTP客户端通过SSL加密连接保护您的数据安全等。

Serv-U 是目前众多的FTP 服务器软件之一。通过使用Serv-U，用户能够将任何一台PC 设置成一个FTP 服务器，这样，用户或其他使用者就能够使用FTP 协议，通过在同一网络上的任何一台PC与FTP 服务器连接，进行文件或目录的复制，移动，创建，和删除等。这里提到的FTP 协议是专门被用来规定计算机之间进行文件传输的标准和规则，正是因为有了象FTP 这样的专门协议，才使得人们能够通过不同类型的计算机，使用不同类型的操作系统，对不同类型的文件进行相互传递。　　

虽然目前FTP 服务器端的软件种类繁多，相互之间各有优势，但是Serv-U 凭借其独特的功能得以展露头脚。具体来说，Serv-U 能够提供以下功能：
符合windows 标准的用户界面友好亲切，易于掌握。
支持实时的多用户连接，支持匿名用户的访问；
通过限制同一时间最大的用户访问人数确保PC 的正常运转。
安全性能出众。在目录和文件层次都可以设置安全防范措施。
能够为不同用户提供不同设置，支持分组管理数量众多的用户。
可以基于IP 对用户授予或拒绝访问权限。
支持文件上传和下载过程中的断点续传。
支持拥有多个IP 地址的多宿主站点。
能够设置上传和下载的比率，硬盘空间配额，网络使用带宽等，从而能够保证用户有限的资源不被大量的FTP 访问用户所消耗。
可作为系统服务后台运行。
可自用设置在用户登录或退出时的显示信息，支持具有UNIX 风格的外部链接。

英文简介

Serv-U 7.2.0.0 was released July 16, 2008. A complete list of changes and upgrades follows:

Features:

• Added support for FTP Voyager JV to run on the Mac OS X operating systems that have Apple's Java SE 6 update installed.
• Added support for Apple Safari.
• Added support for Mozilla Firefox 3.
• Greatly decreased memory usage while maintaining user collections in the Management Console, especially while working with very large numbers of users.
• Improved database access times, mostly apparent while the Management Console is building the database users list.
• Added support for Oracle databases. Tested with Oracle XE.
• Added the ability to set a maximum disk space size for a domain, configurable only by a system administrator, not a domain administrator. This feature allows hosting companies to limit the amount of disk space used by a single domain.
• Added the "Venture" theme for the tray icon.
• Decreased memory usage while upgrading from Serv-U 6.x.
• Added Russian language installation.
• Added the ability to manually enter a directory path to go to in the Basic Web Client.
• Added an upgrade message (when upgrading from Serv-U 6.x) that explains message variable formats have changed to start with "$" instead of "%". Message files must be converted manually.
• Updated Swedish, Finish, Norwegian, and Danish strings.
• Improved the Basic Web Client upload error handling. When errors occur during an upload, the Basic Web Client now displays an error message on certain failures such as insufficient disk space and over quota messages.
• Improved the FTP Voyager JV upload error handling. When errors occur during an upload, the Basic Web Client now displays an error message on certain failures such as insufficient disk space and over quota messages.
• Added the ability to switch domains (using Virtual Hosts) during login for FTP clients that do not user or support the HOST command. The format for the USER command is "USER SP FQDN | username CRLF" where FQDN is the Serv-U virtual host (i.e., "USER host|userid").
• Added the ability to switch domains (using Virtual Hosts) during login for SSH clients. The user ID can be specified as the virtual host name, followed by "|" then the login ID.
• After a successful HOST FTP command, Serv-U also returns the sign on message for that domain.
• Changed the use of the PASV port range to circulate through each of the ports instead of using the first available port. This was done so that some NAT routers work better with Serv-U and to be more consistent with previous versions of Serv-U.

Bug Fixes:

• Corrected a bug on some systems when running as a service when access to removable drives was enabled only for the console user, not the service account (via HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon, values allocatefloppies, allocatedasd, and allocatecdroms set to 1), Serv-U would prompt for a password when trying to configure Serv-U via the tray application.
• Corrected a bug where clicking the next button in the Media Player dialog when the last media file is selected would cause an error.
• Corrected a bug in the Tray's Theme Editor where the "Running" and "Listening Error" states were reversed.
• Corrected a bug in Serv-U's Group support where Serv-U was not ignoring the letter case of a group name, so when using database configurations from Serv-U 6.4 and lower, Serv-U would not recognize matching groups. In some cases this could lead to excessive use of memory. Servers not configured by previous versions data set are not affected.
• Corrected a bug where user collections were letter case sensitive by name.
• Corrected a bug in FTP Voyager JV where the application would become unresponsive when attempting to open certain local file types.
• Corrected a bug in FTP Voyager JV where date/time formats for different regions would cause FTP Voyager JV to become unresponsive at startup.
• Corrected a bug in FTP Voyager JV where overwritten files were not being refreshed with the updated file information.
• Corrected a bug in FTP Voyager JV where the formatted text in the transfer table's "Name" column was including directories for the number of files in the transfer group.
• Corrected a bug where window load events in the web browser were not being handled correctly. FTP Voyager JV would not automatically load due to this bug.
• Corrected a bug where backgrounds were being shown on images in the web page for starting FTP Voyager JV, when running Internet Explorer 6.
• Corrected a bug where the horizontal scroll bar would be shown in certain grids due to a sizing problem with grid columns.
• Corrected a bug where the FTP command, MDTM, was not allowing dates and times to be set on directories.
• Corrected a bug where the "Always allow login" input check box in domain groups was not being saved correctly.
• Corrected a bug where using Upload/Download Ratios could cause Serv-U to crash (GPF) when a user logs off.
• Corrected an HTTP quota bug where quotas were being ignored, and bytes would be counted double.
• Corrected a quota bug where the current quota bytes could go negative.
• Corrected a quota bug where overwriting existing files from the first position in the file (i.e., not resuming), would not restore credit to the quota.
• Corrected a quota bug where bytes uploaded were being recorded even when a quota was not in place.
• Corrected a bug where transparent PNG images on the login page were not rendering correctly when using IE 6.
• Corrected a Management Console bug where the rows in certain tables would not be displayed.
• Corrected a bug where changing the listener to a different type, but keeping it on the same port, would cause Serv-U to think it wasn't listening correctly, showing warning icons in the listener list and on the tray. This was a rare user configuration bug, and only occurs due to user action.
• Corrected a bug where Serv-U would attempt to recreate listening sockets when it didn't need to. This didn't affect Serv-U's performance, but this timed operation did use unnecessary CPU cycles.
• Corrected a problem where the floppy drive could be accessed when starting the tray's Management Console.
• Corrected a problem in the Management Console where images in the alert dialog would be broken if the connection with Serv-U was lost.
• Corrected a bug when using a Domain or Server level FTP message file containing a blank line, Serv-U could crash (GPF).
• Corrected a bug where setting a directory access rule maximum size for %HOME% or a directory containing %USER% would be ignored.
• Corrected a bug where setting a directory access rule for a directory without the Inherit permission, would cause listings using specific file names or wildcard file names to fail with a "Permission Denied" error.
• Corrected a wildcard permission problem where specifying wildcard access prior to other access, the wildcard access may not work as it did in previous versions.
• Corrected a permissions bug when resuming an upload. Serv-U was requiring delete permissions when append permissions were required for the resume. Delete permissions are only required when resuming anywhere other than at the end of the file.
• Corrected a bug where $DFree was returning the free disk space in KB instead of MB, as documented.
• Corrected a bug where message files using $IP could incorrectly assume an IP address returned by $IP (or other $ variable starting with a 3 digit number) was part of the FTP response code.
• Corrected a help documentation error where "$ServerDownloadAvgKBs" was documented, where it should have read "$ServerDownloadAvgKBps".
• Corrected a help documentation error that included incorrect information about disabling SSLv2 support.
• Corrected a bug where $UNonAnonAll could return a huge number (18,446,744,073,709,551,615 [0xFFFFFFFFFFFFFFF]).
• Corrected a bug where $U24H would return large numbers when HTTP connections also occurred.
• Corrected a bug where the bubble tip on the console page for domain administrators would not be shown.
• Corrected a bug where users just added to Serv-U would be required to change the password immediately instead of the specified number of days.
• Corrected a bug where Serv-U was not allowing "level 1: CA certificate" (the second level) and higher Certificate Authorities to be verified with clients.
• Corrected a bug where certain path fields could not be cleared, such as the Log File Path field for a domain.
• Corrected a database bug where numeric login IDs were being incorrectly selected from the database, due to missing quotation marks in the SQL search string. Databases were considering login ID "1" to be the same as "01".
• Corrected a database bug where custom column mappings were not working.
