我正在尝试这样做nslookup skhdphost1 ，但出现了以下错误。当我尝试nslookup 172.16.xxx.xx再次使用命令进行反向查找检查时，出现相同的错误：
错误信息是：
[root@skhdphost1 ~]# nslookup 172.16.xxx.xx
Server: 8.8.8.8
Address: 8.8.8.8#53
** server can't find xxx.xxx.16.172.in-addr.arpa.: NXDOMAIN
[root@skhdphost1 ~]#
我的设置如下：
/etc/hosts文件中的条目
172.16.xxx.xx skhdphost1.example.com skhdphost1
/etc/sysconfig/network文件中的条目
NETWORKING=yes
#HOSTNAME=skhdphost1
HOSTNAME=skhdphost1.example.com
PEERDNS=no
GATEWAYDEV=eth5
GATEWAY=172.16.xxx.xxx
进入/etc/resolv.conf
nameserver 8.8.8.8
nameserver 172.16.xxx.xx
进入/etc/nsswitch.conf
[root@skhdphost1 ~]# vi /etc/nsswitch.conf
# up nothing. Note that if the search failed due to some other reason
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Valid entries include:
#
# nisplus Use NIS+ (NIS version 3)
# nis Use NIS (NIS version 2), also called YP
# dns Use DNS (Domain Name Service)
# files Use the local files
# db Use the local database (.db) files
# compat Use NIS on compat mode
# hesiod Use Hesiod for user lookups
# [NOTFOUND=return] Stop searching if not found so far
#
# To use db, put the "db" in front of "files" for entries you want to be
# looked up first in the databases
#
# Example:
#passwd: db files nisplus nis
#shadow: db files nisplus nis
#group: db files nisplus nis
passwd: files
shadow: files
group: files
#hosts: db files nisplus nis dns
hosts: files dns
# Example - obey only what nisplus tells us...
#services: nisplus [NOTFOUND=return] files
#networks: nisplus [NOTFOUND=return] files
#protocols: nisplus [NOTFOUND=return] files
#rpc: nisplus [NOTFOUND=return] files
#ethers: nisplus [NOTFOUND=return] files
#netmasks: nisplus [NOTFOUND=return] files
bootparams: nisplus [NOTFOUND=return] files
ethers: files
netmasks: files
networks: files
protocols: files
rpc: files
services: files
netgroup: nisplus
publickey: nisplus
automount: files nisplus
aliases: files nisplus
我在上述更改后重新启动了网络，但它不起作用。你能给我建议解决方案吗？
