HP UNIX的用户名密码问题

woshiyiziyu

我有两台HP-UX的机器192.168.100.228和192.168.100.232，两台机器上装的hp-unix操作系统的版本是一样的
192.168.100.228
hp8420a1[/]#uname -a
HP-UX hp8420a1 B.11.11 U 9000/800 1571746837 unlimited-user license
192.168.100.232
[hp8420a3]/#uname -a
HP-UX hp8420a3 B.11.11 U 9000/800 1571746837 unlimited-user license
在这两台机器上我都安装了sybase数据库，数据库的版本也是一样的，都是12.5.0.3.
$ dataserver -v
Adaptive Server Enterprise/12.5.0.3/EBF 11447 ESD#4/P/HP9000-879/HP-UX 11.0/rel12503/1939/64-bit/FBO/Sun Sep 21 06:02:05 2003

一件很奇怪的事情发生了
在192.168.100.228上我可以正常登陆
$ isql -Usa -PPos@07 -Smkt07                                          
1>

但是在192.168.100.232上则不可以，
$ isql -Usa -PPos@10 -Smkt10
sh: Mkt10:  not found.
经过仔细的研究发现是HP-UNIX操作系统的问题，192.168.100.232不识别特殊字符@，需要进行转义处理---在@前加反斜杠即可
$ isql -Usa -PPos\\@Mkt10 -Smkt10

经过仔细的对比我没有看出这两台机器的sybase用户环境变量有什么“本质”的区别。
此外我还做了如下实验，在192.168.100.228（包含@但是可以正常登陆的服务器）上添加了一个测试帐户
hp8420a1[/]#useradd suncs
hp8420a1[/]#passwd suncs
Changing password for suncs
New password:
Re-enter new password:
Passwd successfully changed   （密码是qazwsx）
新开一个窗口使用用户suncs可以正常登陆192.168.100.228
再次更改suncs的密码
hp8420a1[/]#useradd suncs
hp8420a1[/]#passwd suncs
Changing password for suncs
New password:
Re-enter new password:
Passwd successfully changed    （密码是pos@sun)
再次用suncs登陆系统的时候输入密码[email=pos@sun]pos@sun[/email]不能登陆，输入pos\\@sun可以正常登陆。
我最终的问题是为什么我的机器一台可以正常登陆，另一台却必须要在@前加上\\号才可以正常登陆呢？期待高手解答。

是不是跟什么密码策略有关的?

这就奇怪了，两台机器配置都一样的啊

经过仔细的研究发现是HP-UNIX操作系统的问题，192.168.100.232不识别特殊字符@，需要进行转义处理---在@前加反斜杠即可
$ isql -Usa -PPos\\@Mkt10 -Smkt10

就是说为什么在sybase数据库的密码中包含@符号时需要在前面加\\号，系统才能识别？又为什么在su - root之后在su - sybase 之后系统就能识别了呢？

楼上的，为什么另外一台机器没有这种情况呢
