Solaris 11 DNS Client 設定

Solaris 11  DNS Client 設定

檢查現有的DNS Client 設定
root@s11:~# svccfg -s network/dns/client listprop config
config                      application
config/value_authorization astring     solaris.smf.value.name-service.dns.client

更新 DNS Client 設定
root@s11:~# svccfg -s network/dns/client setprop config/nameserver = net_address: "(168.95.1.1  8.8.8.8)"

root@s11:~# svccfg -s network/dns/client setprop config/domain = astring: test.com.tw

root@s11:~# svccfg -s network/dns/client setprop config/search = astring: '("test.com.tw" "test1.com.tw")'


設定名稱解析順序
root@s11:~# svccfg -s name-service/switch setprop config/ipnodes = astring: '("files dns")'
root@s11:~# svccfg -s name-service/switch setprop config/host = astring: '("files dns")'

檢視DNS Client變更的設定
root@s11:~# svccfg -s network/dns/client listprop config
config                      application
config/value_authorization astring     solaris.smf.value.name-service.dns.client
config/nameserver          net_address 168.95.1.1 8.8.8.8
config/domain              astring     test.com.tw
config/search              astring     "test.com.tw" "test1.com.tw"
root@s11:~#

檢視nsswitch變更的設定
root@s11:~# svccfg -s name-service/switch listprop config
config                      application
config/default             astring     files
config/value_authorization astring     solaris.smf.value.name-service.switch
config/printer             astring     "user files"
config/ipnodes             astring     "files dns"
config/host                astring     "files dns"

匯出DNS Client 設定組態
root@s11:~# svcadm enable dns/client

root@s11:~# more /etc/resolv.conf                                    (此時檢視/etc/resolv.conf並不存在)

root@s11:~#  nscfg export svc:/network/dns/client:default
root@s11:~# more /etc/resolv.conf                                     (此時檢視/etc/resolv.conf已建立)

此設定reboot 設定會清除

I. DNS client setup

1. 設定network/dns/client  SMF 服務 

# svccfg -s network/dns/client

svc:/network/dns/client> setprop config/search = astring: ("test.com.tw""test1.com.tw")

svc:/network/dns/client> setprop config/nameserver = net_address: (168.95.1.1 8.8.8.8)

svc:/network/dns/client> exit

2. 開啟 DNS client 服務 (第一次使用需要設定)

#svcadm enable -r dns/client

3.重啟/更新 DNS client 服務 (當設定完成或是有任何更新時)

#svcadm refresh dns/client

#svcadm restart dns/client

4. 檢查設定完成後/etc/resolv.conf 是否有更新(出現紅字部份)

# more /etc/resolv.conf

#

# _AUTOGENERATED_FROM_SMF_V1_

#

# WARNING: THIS FILE GENERATED FROM SMF DATA.

#   DO NOT EDIT THIS FILE.  EDITS WILL BE LOST.

# See resolv.conf(4) for details.

search           cht.com.tw cht1.com.tw

nameserver      xx.xx.xx.xx

nameserver      yy.yy.yy.yy

---

II.  設定Name service switch 使用 DNS

1. 設定 system/name-service/switch SMF 服務

# svccfg -s system/name-service/switch

svc:/system/name-service/switch> setprop config/host = astring: "files dns"

svc:/system/name-service/switch>end

2.  .重啟/更新 name-service/switch 服務

#svcadm refresh name-service/switch

#svcadm restart  name-service/switch

3. 檢查設定完成後/etc/nsswitch.conf檔，出現紅字部份的更新)

# more /etc/nsswitch.conf

#

# _AUTOGENERATED_FROM_SMF_V1_

#

# WARNING: THIS FILE GENERATED FROM SMF DATA.

#   DO NOT EDIT THIS FILE.  EDITS WILL BE LOST.

# See nsswitch.conf(4) for details.

passwd: files

group:  files

hosts:  files dns

ipnodes:        files dns

.

最後nslookup試試看DNS是否解析
