在hostB安裝execution host出現error: commlib error: access denied錯誤

hostSG是GRID系統的Master Host,而hostB則是預計要安裝execution host的設備

安裝方式是使用root帳號在$SGE_ROOT路徑下執行.\inst_sge -x

安裝的過程中出現的錯誤訊息如下:

Checking hostname resolving
---------------------------

Cannot contact qmaster. The command failed:

   ./bin/lx24-amd64/qconf -sh

The error message was:

   error: commlib error: access denied (client IP resolved to host name "hostA". This is not identical to clients host name "hostB")
ERROR: unable to contact qmaster using port 5536 on host "hostSG"

You can fix the problem now or abort the installation  procedure.
The problem can be:

   - the qmaster is not running
   - the qmaster host is down
   - an active firewall blocks your request

解法:
將hostSG的/etc/hosts檔案內容中的 "192.168.1.100 hostA"設定移除即可排除
hostA是工作站網路中不存在的設備名稱
