各位PTT linux的版友大家好~~
我用centos 6.9 架了一台EDA server 的工作站 ,主要是給學生練習畫IC layout用的 ~~
遠段連線採用SSH 和 NXfree 連接~~
最近架站試測,有一些問題~~就是主機閒置久了...遠端就登入不進去...就timeout
後來去主機端看一下...就帳號登出,重新開機又可以遠端連線了~~
主機端電腦,我不是用root開機,是用一般帳號開機,主要是怕用root開機,會被上課的學生
動到...
所以用一般帳號開機~~~還是要用root開機才可以.....
還有我的server的電源管理選項有設置永遠不關機....也把電腦螢幕保護程式也關了
主機server用一般帳號開機,閒置過久還是會登出.....
我要怎讓它一直在開機狀態...不登出...
最後,我有個小小一疑問...會不會我防火牆設定的不好(我用圖形介面設的)...主機被攻
到帳號登出....有沒有這可能 XD
謝啦~~~~
