以NASA Wind World为例，SF上的提示如下：

Anonymous CVS Access
This project's SourceForge.net CVS repository can be checked out through anonymous (pserver) CVS with the following instruction set. The module you wish to check out must be specified as the modulename. When prompted for a password for anonymous, simply press the Enter key. To determine the names of the modules created by this project, you may examine their CVS repository via the provided web-based CVS repository viewer.
cvs -d:pserver:anonymous@nasa-exp.cvs.sourceforge.net:/cvsroot/nasa-exp login
cvs -z3 -d:pserver:anonymous@nasa-exp.cvs.sourceforge.net:/cvsroot/nasa-exp co -P modulename
Information about accessing this CVS repository may be found in our document titled, "CVS (Version Control for Source Code)".
Updates from within the module's directory do not need the -d parameter.
NOTE: UNIX file and directory names are case sensitive. The path to the project CVSROOT must be specified using lowercase characters (i.e. /cvsroot/nasa-exp)
1、安装TortoiseCVS-1.8.29.exe
2、新建一个文件夹
3、右键chech out，在CVSROOT中输入
:pserver;proxy=192.9.104.105;proxyport=808:anonymous@nasa-exp.cvs.sourceforge.net:/cvsroot/nasa-exp
红色部分是我用的代理服务器地址，修改之。
4、不出什么问题，应该就ok了。
