suse 11sp3 -不能平/解析自己的主机名

Question

我有一个本地虚拟机(运行在本地安装的vmware工作站上，网络设置为NAT)，我已经在上面安装了suse 11 sp3。

这台机器被设置为使用dhcp (从vmware)获得一个ip地址，这是可行的--至少我有互联网连接。

问题是它无法解决自己的主机名：

suse11:~ # hostname
suse11
suse11:~ # ping suse11
ping: unknown host suse11
suse11:~ # ping www.google.com
PING www.google.com (74.125.131.99) 56(84) bytes of data.

我不想将主机名添加到/etc/host中，作为127.0.0.1。理想情况下，我希望与windows上的行为相同--将您自己的主机名解析为“真实的”ip地址(可能是众多ip地址中的一个)。

/etc/resve.conf：

### /etc/resolv.conf file autogenerated by netconfig!
#
# Before you change this file manually, consider to define the
# static DNS configuration using the following variables in the
# /etc/sysconfig/network/config file:
#     NETCONFIG_DNS_STATIC_SEARCHLIST
#     NETCONFIG_DNS_STATIC_SERVERS
#     NETCONFIG_DNS_FORWARDER
# or disable DNS configuration updates via netconfig by setting:
#     NETCONFIG_DNS_POLICY=''
#
# See also the netconfig(8) manual page and other documentation.
#
# Note: Manual change of this file disables netconfig too, but
# may get lost when this file contains comments or empty lines
# only, the netconfig settings are same with settings in this
# file and in case of a "netconfig update -f" call.

### Please remove (at least) this line when you modify the file!

/etc/nsswitch.conf：

# /etc/nsswitch.conf

# An example Name Service Switch config file. This file should be
# sorted with the most-used services at the beginning.
#
# The entry '[NOTFOUND=return]' means that the search for an
# entry should stop if the search in the previous entry turned
# 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.
#
# Legal entries are:
#
#       compat                  Use compatibility setup
#       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
#       [NOTFOUND=return]       Stop searching if not found so far

Answer 1

这种行为是预期的，名称服务器根据域名空间解析主机名。它与它/etc/主机的工作方式无关。

如下所述：

运行ping suse11时，首先尝试使用/etc/host解析，因为suse11不存在，然后尝试使用名称服务器192.168.19.2，但要注意/etc/surv.conf中的“搜索本地域”，以便将其附加到“查询”，因此192.168.19.2尝试解析suse11.localdomain，这样的域在公共名称空间中不存在。

ping不是测试主机解析的工具，也不是用来测试主机解析的工具。

您可以更好地使用真正的DNS查找工具，例如：

dig @192.168.19.2 suse11

加入windows域时，PDC中集成的dhcp服务在windows DNS服务中添加一个dns A记录，因此您可以解析windows域网络中的Windows pc
