@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
d6:54:24:a7:1d:76:bd:75:ea:ce:cd:0a:66:fe:bf:1d.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending key in /root/.ssh/known_hosts:1
RSA host key for 192.168.1.71 has changed and you have requested strict checking.
Host key verification failed.
lost connection
解決方法:
vi ~/.ssh/known_hosts
進入此目錄，刪除192.168.1.90的相關rsa的信息即可.
或者刪除這個文件
cd ~/.ssh/
rm known_hosts
問題二: vi 文件的時候，提示有swap文件
解決：rm .vsftpd.conf.swap 該文件被隱藏
問題三：查看linux 系統32和64
[[email protected]]# getconf WORD_BIT
