图文详解TCP_IP基础原理和技术电子书pdf下载

因为network 和 hosts文件中的主机名不一样.

查了一下自己的服务器配置,果然两个文件的主机名不一样,hosts中的主机名是默认的.

[root@server ~]# cat /etc/sysconfig/network 

NETWORKING=yes 

NETWORKING_IPV6=no 

HOSTNAME=server

[root@server ~]# cat /etc/hosts 

# Do not remove the following line, or various programs 

# that require network functionality will fail. 

127.0.0.1              localhost.localdomain localhost 

::1             localhost6.localdomain6 localhost6

将hosts文件中的主机名也改成和network中的主机名一样(如下),哇,那速度是相当地快!

[root@server ~]# cat /etc/hosts 

# Do not remove the following line, or various programs 

# that require network functionality will fail. 

#127.0.0.1              localhost.localdomain localhost 

127.0.0.1               server 

::1             localhost6.localdomain6 localhost6
