     Description:         A free socks4,5 and msproxy implementation

但请注意,密码以明文形式传输.

要配置基于用户名的身份验证,请打开/etc/sockd.conf文件并添加/更改以下内容：

logoutput: syslog /var/log/dante.log

# methods for socks-rules.
method: username #rfc931

# when doing something that can require privilege,# it will use the userid "sockd".
user.privileged: root

# when running as usual,# it will use the unprivileged userid of "sockd".
user.notprivileged: sockd

pass {
    from: 0.0.0.0/0 to: 0.0.0.0/0
    protocol: tcp udp
    command: bind connect udpassociate
    log: error
    method: username
}

启动后检查监听套接字：

# netstat -nlp | grep sockd
tcp        0      0 127.0.0.1:1080          0.0.0.0:*               LISTEN      5463/sockd          
tcp        0      0 192.168.15.36:1080      0.0.0.0:*               LISTEN      5463/sockd

如果出错,请查看日志文件(/ var / log / messages或/var/log/dante.log).

PS：系统密码文件(/ etc / passwd)用于验证用户名和密码组合.
