pydhcpdparser 0.0.9

示例

如果将dhcpd配置输入到pydhcpdparser，则为

subnet 10.198.146.0 netmask 255.255.255.192 {
    pool {
         failover peer "az-dhcp-failover";
         range 10.198.146.4 10.198.146.62;
    }
    option routers 10.198.146.1;
    option broadcast-address 10.198.146.63;
    option domain-name "some.domain.net";
    option domain-name-servers 10.24.199.136,10.24.199.137;
}

pydhcpdparser验证dhcpd语法，解析并返回 pythonic结果为

[{'netmask': '255.255.255.192',
 'option': {'broadcast-address': '10.198.146.63',
            'domain-name': '"some.domain.net"',
            'domain-name-servers': '10.24.199.136,10.24.199.137',
            'routers': '10.198.146.1'},
 'pool': {'failover': ('peer', '"az-dhcp-failover"'),
          'range': ('10.198.146.4', '10.198.146.62')},
 'subnet': '10.198.146.0'}]

用法

importpydhcpdparserconf="""
subnet 10.198.146.0 netmask 255.255.255.192 {
    pool {
         failover peer "az-dhcp-failover";
         range 10.198.146.4 10.198.146.62;
    }
    option routers 10.198.146.1;
    option broadcast-address 10.198.146.63;
    option domain-name "some.domain.net";
    option domain-name-servers 10.24.199.136,10.24.199.137;
}
