请教2个问题

netrommel

我在工作中遇到了2个问题，想请教一下\r\n一个是可否在/etc/passwd和/etc/shadow中把root用户改成其它的名字，也就是把超级用户改成其它的用户名？windows环境中是可以把administrtor改成别的用户，所以我想知道solaris里是否也可以\r\n\r\n另外一个问题是我想隐藏ssh的版本号，网上的资料一般都是修改banner或是先卸掉原来的ssh，重新编译ssh的源程序，再重新安装。修改banner的办法没有任何效果，而重新编译ssh的源程序，再重新安装太麻烦，有时有的用户环境也不一定允许，请教有什么更好更简单的办法吗？

Solaris 9 and 10 should come with ssh built-in. Unless you download and install open ssh by yourself, you shouldn\'t  see ssh version number. For Solaris 8, you have to install openssh separately. Where do you see the version number? Is it before or after login? Which version of ssh are you using? In which OS version do you see the ssh version number?

There are a lot of people spending their precious time help others such as  风之幻想, race, yuhuohu, 东方蜘蛛 ... So your 致敬 probably should go to all of them.

I got the version number by \r\n\r\ntelnet ip_of_solaris10 22\r\n\r\nthen \r\nI got:\r\n\r\nSSH-2.0-sun_SSH_1.1

That is a protocol announcement for compatibility. It is not recommended to get rid of it. If you really do, I don\'t think there is a easy way but re-compile the source code. The version number should be defined in usr/src/crypto/openssh/version.h file. \r\n\r\nAnother posibility is to use tcpwrapper, which might be able to suppress the version message. But I never tried it before.
