uname和hostname的區(qū)別

ljt98

用uname和hostname都可以實現(xiàn)給機器改名，但是又什么區(qū)別呢，用uname更改過的名字被存放在什么地方？和/etc/hosts中的對應的hostname有什么關(guān)系？？thank u

uname可以改機器名?

改系統(tǒng)名？？
問題是由于需要用uname 將系統(tǒng)改名，但是用圖形界面登陸:給出提示

The DT messaging system could not be started.

To correct the problem:

1.Choose [OK] to return to the login screen.

2.Select Failsafe Session from the login screen's option menu and log in.

3.Check to see that the hostname is correct in these locations:

/etc/src.sh
/etc/hosts
/usr/adm/inetd.sec

For additional information,see the DT User's Guide.

如何解決？
