修改口令 meaning in English

change password

If you want to change your password , you have to contact all servers and notify them of the change
如果你想修改口令，你就必须联系所有服务器，通知它们修改口令。
By the way , when you telnet in to change the password , don t use a real password ; use a dummy password that s not related to any password you actually use , so that when you have ssh set up , and want to set the password without sending it in plain text , you haven t given anything away
随便提一句，当您telnet进入机器并修改口令时，不要使用真正的口令；使用一个与您实际使用的口令毫无关系的假口令，这样，当您设置好ssh ，并想以非纯文本方式发送口令时，您不会有任何损失。
