telnet报错:Name or service not known

telnet报错"Name or service not known"是由于/etc/sysconfig/network和/etc/hosts文件中的主机名不对应所造成的。为了解决这个问题，你需要打开/etc/hosts文件并将其中的IP地址主机名与/etc/sysconfig/network文件中的主机名相对应。具体做法是在/etc/hosts文件中将"127.0.0.1"后面的"localhost.localdomain localhost"改成与/etc/sysconfig/network中一样的主机名。你可以使用vi编辑器打开/etc/hosts文件，找到相应行进行修改。<em>1</em><em>2</em><em>3</em>
