AIX 系统故障之---用户网络通讯错误


环境:

操作系统: AIX 5.3.8

数据库:   Oracle 10.2.0.1

错误现象:

AIX 系统权限错误,普通用户不能进行网络通讯(如rlogin、rsh、rcp、ping)


1、故障现象


[u@h W]$rlogin aix208

rcmd2: socket: Permission denied


[root@aix208 /]#su - oracle

[YOU HAVE NEW MAIL]

[u@h W]$ping aix208

ping: socket: Permission denied


2、查看命令权限


[root@aix208 /]#which rcp

/usr/bin/rcp

[root@aix208 /]#ls -l /usr/sbin/ping

-rwxr-xr-x    1 root     system        32566 Jan  5 2008  /usr/sbin/ping

[root@aix208 /]#ls -l /usr/bin/rsh

-r-sr-xr-x    2 root     system        26244 Jan  5 2008  /usr/bin/rsh

[root@aix208 /]#ls -l /usr/bin/rlogin

-rwxr-xr-x    1 root     bin           29502 Jan  5 2008  /usr/bin/rlogin

[root@aix208 /]#ls -l /usr/bin/rcp  

-rwxr-xr-x    1 root     system        44798 Feb 11 2008  /usr/bin/rcp

[root@aix208 /]#ls -l /usr/sbin/ping

-rwxr-xr-x    1 root     system        32566 Jan  5 2008  /usr/sbin/ping


3、修改命令权限,问题解决


[root@aix208 /]#chmod 4555 /usr/bin/rlogin

[root@aix208 /]#chmod 4555 /usr/bin/rcp  

[root@aix208 /]#chmod 4555 /usr/bin/rsh

[root@aix208 /]#chmod 4555 /usr/sbin/ping

4、测试

[root@aix208 /]#su - oracle

[YOU HAVE NEW MAIL]

[u@h W]$ping aix208
