前言:

眼前大家对“主机与虚拟机互ping”可能比较着重,姐妹们都需要分析一些“主机与虚拟机互ping”的相关文章。那么小编同时在网摘上搜集了一些关于“主机与虚拟机互ping””的相关内容,希望你们能喜欢,看官们快快来学习一下吧!

在使用SecureCRT连接虚拟机时,连接出现异常,很久都没连接上,但是也没有出现报错

直接在虚拟机上ping本地的IP,发现出现了DUP!的状态

[root@test ~]# ping 192.168.133.1

找了找网上的解决方法:

1.清空/etc/udev/rules.d/70-persistent-net.rules :

[root@test ~]# cd /etc/udev/rules.d/

[root@test rules.d]# ll

total 4

-rw-r--r--. 1 root root 628 Sep 26 2019 70-persistent-ipoib.rules

[root@test rules.d]# >70-persistent-ipoib.rules

[root@test rules.d]# ll

total 0

-rw-r--r--. 1 root root 0 Feb 10 18:10 70-persistent-ipoib.rules

2.停掉NetworkManager服务

[root@test]# service NetworkManager stop

Stopping NetworkManager daemon: [ OK ]

3.重启网络服务

[root@orcldg rules.d]# service network restart

Restarting network (via systemctl): [ OK ]

[root@test rules.d]# ping 192.168.133.1

PING 192.168.133.1 (192.168.133.1) 56(84) bytes of data.

64 bytes from 192.168.133.1: icmp_seq=4 ttl=128 time=0.401 ms

64 bytes from 192.168.133.1: icmp_seq=5 ttl=128 time=0.811 ms

网络状态正常,使用SecureCRT连接上了虚拟机
