telnet 报错 getaddrinfo: localhost Name or service not known

系统：Redhat Linux 5.5
登录方式：ssh 登录
刚才发现在系统上不去，提示getaddrinfo: localhost Name or service not known。 因为/etc/sysconfig/network 和 /etc/hosts文件中的主机名不对应造成的~
[root@uttflying ~]# vim /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 Master    localhost

::1     localhost6.localdomain6 localhost6

只要更改hosts文件中，127.0.0.1这行，在后面的localhost.localdomain localhost 添加 network中一样的hostname
[root@uttflying ~]# vim /etc/sysconfig/network

NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=Master
