替代抓取netstat获取远程IP地址列表？

Question

我目前正在刮Mac OSX上的netstat -n -A inet在Linux和netstat -n -f inet输出去，该机器使用以下（Python的默认值）连接的远程IP地址和端口的正则表达式的集合：

'(?:[0-9]+\.){3}[0-9]+[.:][0-9]+\s+((?:[0-9]+\.){3}[0-9]+)[.:]([0-9]+)' 

这给了我在第1组的远程IP和第2组

远程端口然而，这似乎并没有携带或维护（并仅限于IPv4地址）。

是否有越来越活跃的远程IP地址的列表，一个更好的选择？

Answer 1

如果你不害怕C和U的* X内部构件，你可以反向工程的netstat。

采取这里看看https://unix.stackexchange.com/questions/21503/source-code-of-netstat

Answer 2

嘛，总是有SNMP ...完整的TCP连接表是在.1.3.6.1.2.1.6.19（也称为.iso.org.dod.internet.mgmt.mib-2.TCP .tcpConnectionTable），完整的UDP表格位于（也称为.iso.org.dod.internet.mgmt.mib-2.udp.udpEndpointTable）。

这里是我的本地Linux系统中的一个例子：

$ snmpbulkwalk -v2c -c xxxx -m ALL 83.137.17.100 .iso.org.dod.internet.mgmt.mib-2.tcp.tcpConnectionTable 
TCP-MIB::tcpConnectionState.ipv4."83.137.17.100".44463.ipv4."91.189.89.90".80 = INTEGER: timeWait(11)

净SNMP工具使输出有点更具可读性。以数字形式第一输出线将是：

1.3.6.1.2.1.6.19.1.7.1.4.83.137.17.100.44463.1.4.91.189.89.90.80 = INTEGER: 11 

或者在完全展开的文本：

.iso.org.dod.internet.mgmt.mib-2.tcp.tcpConnectionTable.tcpConnectionEntry.tcpConnectionState.ipv4."83.137.17.100".44463.ipv4."91.189.89.90".80 

我不知道这是任何比你现在正在做什么容易，但它为标准化的方式...
