ssh?

一样的配置，A机能SSH到B机，但B机SSH到A机提示如下：
[root@BBN ssh]# ssh 172.16.12.60

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

It is also possible that the RSA host key has just been changed.

lost connection
[root@BBN ssh]#

请问这是怎么回事呢！

试过 ssh -l yourusername 172.16.12.60 吗？

呵呵，我昨天搞定了，大家猜怎么着，我换了一个IP就OK了，真是晕！要是我用静态的IP，不能换地址的那岂不是死定了啊，难道一定要换IP才能成功的吗？

从A机上将.ssh/know_hosts中相映的公匙删去即可。

或者用vi 将那地址在know_hosts中去掉
