SL7.1 (EL7.1) 领域发现未发现

Question

尝试将 SciLinux 7.1 (EL7.1) 盒子加入在 Windows 2008R2 64 位上运行的 AD 域。

遵循 Red Hat Enterprise Linux 7 Windows 集成指南：

$ sudo realm discover -v mems.local
 * Resolving: _ldap._tcp.mems.local
 * Resolving: mems.local
 ! Discovery timed out after 15 seconds
mems.local
  type: kerberos
  realm-name: MEMS.LOCAL
  domain-name: mems.local
  configured: no

然而：

$ nslookup -type=srv _ldap._tcp.mems.local
 Server:        172.17.21.20
 Address:   172.17.21.20#53

_ldap._tcp.mems.local   service = 0 100 389 mwinds2.mems.local.
_ldap._tcp.mems.local   service = 0 100 389 mwinds1.mems.local.

现在我该怎么做？

# realm join mems.local
See: journalctl REALMD_OPERATION=r1063.5453
realm: Cannot join this realm

# journalctl REALMD_OPERATION=r1063.5453

Jul 29 15:08:25 playbox.mems.local realmd[5456]:  * No results: mems.local

# nslookup _ldap._tcp.mems.local
Server:         172.17.21.20
Address:        172.17.21.20#53

*** Can't find _ldap._tcp.mems.local: No answer

# nslookup -type=srv _ldap._tcp.mems.local
Server:         172.17.21.20
Address:        172.17.21.20#53

_ldap._tcp.mems.local   service = 0 100 389 mwinds2.mems.local.
_ldap._tcp.mems.local   service = 0 100 389 mwinds1.mems.local.

$ tcping mwinds1 389
mwinds1 port 389 open.

Answer 1

如果有人偶然发现这个问题，这里是修复我的 Ubuntu 14.04 框的原因，我的域名一直超时。

编辑/etc/nsswitch.conf：

使主机行看起来像这样 -

hosts:          files dns mdns4_minimal [NOTFOUND=return] mdns4

然后再次尝试您的发现。
