linux下能ping ip不能ping域名
今天在開(kāi)發(fā)的同事來(lái)說(shuō),內(nèi)網(wǎng)不能通過(guò)域名訪問(wèn)自己的服務(wù)器!然后做了下面的測(cè)試發(fā)現(xiàn)這樣的問(wèn)題:
[root@itmop ~]# ping www.aimjoke.net
ping: unknown host www.aimjoke.net
[root@itmop ~]#ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=0.537 ms
64 bytes from 192.168.1.1: icmp_seq=2 ttl=64 time=0.430 ms
— 192.168.1.1 ping statistics —
2 packets transmitted, 2 received, 0% packet loss, time 999ms
rtt min/avg/max/mdev = 0.430/0.483/0.537/0.057 ms
[root@itmop ~]#cat /etc/host.conf
order bind,hosts
經(jīng)過(guò)一翻查找后解決了,原因和方法如下:
[root@itmop ~]# grep host /etc/nsswitch.conf
#hosts: db files nisplus nis dns
hosts: files
主機(jī)只找文件不走dns,將其該成hosts: files dns 即可!
關(guān)鍵詞:linux,ping
