Mandriva 2010 2 telnet 登录bbs出错问题

今天晚上，在Mandriva 2010 2下telnet 登录bbs，出现错误：

 

Encryption could not be enabled.

 

在网上找了一篇文章，等几天后再仔细看看

续：

登录时，使用telnet -a bbs.sjtu.edu.cn即可，加上选项-a。

 

The encryption in telnet is based upon a shared secret key, not a public/private key system. The shared secret is established with kerberos authentication. If you do not have valid kerberos tickets, you can not establish a secure and encrypted connection with our current telnet client or telnet server programs. To use telnet client program, type: telnet -a hostname This will attempt to establish an encrypted telnet connection to hostname and automatically log you in without typing a password. (This procedure will not give you kerberos tickets on the remote host; you must use kinit.)
