uname和hostname的区别

ljt98

用uname和hostname都可以实现给机器改名，但是又什么区别呢，用uname更改过的名字被存放在什么地方？和/etc/hosts中的对应的hostname有什么关系？？thank u

uname可以改机器名?

ljt98

改系统名？？
问题是由于需要用uname 将系统改名，但是用图形界面登陆:给出提示

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.

如何解决？
