openldap-2.4.15 RPM包发布

不知道多少人用openldap 2.4，网络上2.4的版本RPM包比较少，可能有人会需要2.4的包，因此将我的RPM包发布出来，给需要的同学一点方便。推荐目前使用最新的 2.4.16，2.4.13后的版本解决了不少BUG，尤其是同步中的比较大的问题。RPM包是我自己在前人2.4.11基础上，打出来的。目前我自己使用稳定。
有需要的同学可以在这里下载:

http://yum.ZYMLinux.net/repo/

这些包都是在CentOS 5.x 4.x最新版本上打包并验证使用，repo里有SRPM 和x86_64/i386的包，其他环境可以直接用rpmbuild --rebuild来搭建。所有RPM包，都用 47DA782A 的GPG KEY签名。关于此包的任何问题，可以联系我。

注意事项：

1，2.4同时支持2种配置文件方式，一个是-f /etc/openldap/slapd.conf文件方式，另一个是 -F /etc/openldap/slapd.d 目录方式，推荐使用目录方式，非常有利于高级管理。
2，安装中，会提示可能有些包缺失，建议采用增加repo的方式用yum安装。或者先根据提示安装上缺失的包。
3，一般应使用rpm -U安装，这是因为x86_64同时也装了i386兼容包，建议使用我提供的repo方式安装。

附最近的changelog
* 20090413:
o 升级openldap 到2.4.16，做了CentOS 4.x的包
o 老站无法更新，换到了北京的机器
o update openldap to version 2.4.16, with CentOS 4.x package
o old 61.156.7.131 is not updatable now, please retire it.
* 20090316：
o copy openldap compat-openldap i386 rpms to x86_64, that will make yum happy with x86_64 profile
o x86_64直接执行yum update将不再文件冲突报错。
* 20090305：
o 升级到2.4.15 v1.1，增加pw-sha2支持SHA-512, SHA-384 and SHA-256。
o 升级db 4.6.21的补丁到p4。
* 20090305：
o 升级到2.4.15，目前repo里支持2.4.14/15的CentOS 5 i386/x86_64版本

如何使用socks代理服务器执行ssh以及其他类似命令

经常有人会希望有个方便的代理，有时是想测试网络啊，SA们多数有N多的Linux机器，socks代理可以采用tsocks的解决方案。

使用tsocks解决方案：

需要tsocks：

[I] net-proxy/tsocks
    Available versions:  1.8_beta5-r2 1.8_beta5-r3 {tordns}
    Installed versions:  1.8_beta5-r3(23时11分28秒 2008年07月30日)(-tordns)
    Homepage:            http://tsocks.sourceforge.net/
    Description:         Transparent SOCKS v4 proxying library

修改/etc/socks/tsocks.conf文件，根据需要增加reaches行：

local = 127.0.0.1/255.255.255.255 #localhost
path {
       reaches = 0.0.0.0/0.0.0.0 #default
       server = 127.0.0.1
       server_type = 5
}

#tordns_enable = yes

使用tsocks ssh .... 来连接任何机器，走的命令ssh就会直接转到localhost 1080代理上了。其他任何需要用socks代理的命令，前面加上tsocks就可以了。

优点：
- 命令行可用，对任何程序，不论是否支持socks，如需要启用socks转发，直接前面加上tsocks即可。
- 不影响系统运行，默认不会应用不会走socks代理。
- 此配置为配好ssh -D选项，可以非常方便的把连接转发到任何机器上。
