请教一个wall的问题

kewang

如何使wall的信息只发给root用户,不发给终端!\r\n不将wall改名 ,有什么好的办法吗

yddll

man wall看到:\r\n -g Group         Broadcasts to a specified group only.\r\n\r\n要不你试试？

各位,报谦,我没有说明白,不是手工mail,而是系统发生了故障,\r\n\r\n比如一个电源坏掉了什么的,这样系统就会向终端不停的发wall信息\r\n\r\n搞的终端都不能用了,有什么办法能使wall信息不发给终端,\r\n\r\n除了将wall命令改名字!

I guess it\'s the /usr/lpp/diagnostics/bin/diagd daemon that writes this message to crontab,\r\nso,you\'d better repair the power supply,\r\nthe wall message will not appear.\r\n\r\nthis is the thorough method.

0 00,12 * * * wall% rc.powerfail:2::WARNING!!! The system is now operating with a power problem.This message will be walled every 12 hours. Remove this crontab entry after the problem is resolved.\r\n\r\nthe power message will be as this  ?

if you don\'t repair the power,\r\nyou can edit the crontab record as below,\r\n\r\n0 0 31 12 * wall% rc.powerfail:2::WARNING!!! The system is now operating with a power problem.This message will be walled every 12 hours. Remove this crontab entry after the problem is resolved.

我觉得crontab里不一定有wall

if the server have the power problem,\r\n the crontab will be added the wall message.\r\n\r\nlike this:\r\n\r\n0 00,12 * * * wall% rc.powerfail:2::WARNING!!! The system is now operating with a power problem.This message will be walled every 12 hours. Remove this crontab entry after the problem is resolved.
