10.22.22.1ping不通

[helloxz]

服务端运行后信息如下：

客户端信息如下：

无任何报错，但本地无法ping通10.22.22.1，请问是什么原因？

[wangyu-]

先按照这个文章里说的自己排查一下；如果排查后还是不行，补全一下你提供的信息。

1. 服务器、客户端均关闭了iptables
2. 确保服务端已经运行,但是只有udp，无tcp是否正常？

   [root@li1684-104 ~]# netstat -an|grep '4096'
   udp        0      0 0.0.0.0:4096            0.0.0.0:* 

3. 服务器：Linode JP2 Centos X64，本地VMware + CentOS 7虚拟机
4. VMware桥接已指定网卡。 5 .日志 服务端：

确保服务端已经运行,但是只有udp，无tcp是否正常？

正常

你用nc/ncat测试一下4096这个udp端口通不通

[helloxz]

本地客户端nc测试如下，实在找不到哪里原因了。

[root@localhost ~]# nc -u -vvv  172.104.xx.xxx 4096
Ncat: Version 6.40 ( http://nmap.org/ncat )
libnsock nsi_new2(): nsi_new (IOD #1)
libnsock nsock_connect_udp(): UDP connection requested to 172.104.xx.xxx (IOD #1) EID 8
libnsock nsock_trace_handler_callback(): Callback: CONNECT SUCCESS for EID 8 [172.104.xx.xxx:4096]
Ncat: Connected to 172.104.xx.xxx.
libnsock nsi_new2(): nsi_new (IOD #2)
libnsock nsock_read(): Read request from IOD #1 [172.104.xx.xxx] (timeout: -1ms) EID 18
libnsock nsock_readbytes(): Read request for 0 bytes from IOD #2 [peer unspecified] EID 26

本地客户端nc测试如下，实在找不到哪里原因了。

只有一边用nc测不出什么。

两边都换成nc，测试一下能否正常发送数据，双向。

[helloxz]

服务端是固定IP，客户端不是，客户端nc测服务好办。但是服务 -> 本地，那我测试哪个IP？在服务端nc 10.22.22.1？

[wangyu-]

你只要在客户端用nc连server的nc服务端就可以双向发送数据了。不需要反向连接。

[helloxz]

还是没懂，之前不是已经在客户端连接nc的server了吗？

[root@localhost ~]# nc -u -vvv  172.104.xx.xxx 4096

[helloxz]

实在抱歉，把你坑了，我在虚拟机ping 10.22.22.1是通的，但是有个问题请教，我是windows系统，要如何将10.22.22.1转发到我windows来用呢？

[wangyu-]

还是没懂，之前不是已经在客户端连接nc的server了吗？

你只是连上了，不发数据有什么用。之所以用nc，是为了测试从一边发送数据在另一边能否收到。

多谢帮助，问题应该能解决了。
