手机vultr搭建ssr教程
重新搭建服务器:根据需求,选择每个月需要的流量,一般流量越多,钱也越多,我选择的具体如下:选3.5$/m,Server Type:64 bit OS, CentOS:6*64打开终端:先拼地址:Ping 144.202.23.71(买Vultr服务器的地址)ssh root@144.202.23.71然后输入密码:m5S@#?744zeM)U@(Congratulations, Shadowsocks-python server install completed!Your Server IP : 207.246.97.131Your Server Port : 56473Your Password : studyhardYour Encryption Method: chacha20-ietf-poly1305Welcome to visit:https://teddysun.com/342.htmlEnjoy it![root@vultr ~]#执行命令:wget –no-check-certificate https://raw.githubusercontent.com/teddysun/shadowsocks_install/master/shadowsocks.shchmod +x shadowsocks.sh./shadowsocks.sh 2>&1 | tee shadowsocks.log设置完成后:Congratulations, Shadowsocks-python server install completed!Your Server IP : 144.202.23.71Your Server Port : 12528Your Password : teddysun.comYour Encryption Method: aes-256-gcmWelcome to visit:https://teddysun.com/342.htmlEnjoy it!设置小飞机:设置服务器Vultrssh root@144.202.23.71 *** 作时处理异常:在平时工作中,有时候需要SSH登陆到别的Linux主机上去,但有时候SSH登陆会被禁止,并d出如下类似提示:@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@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 is36:68:a6:e6:43:34:6b:82:d7:f4:df:1f:c2:e7:37:cc.Please contact your system administrator.Add correct host key in /u/xlian008/.ssh/known_hosts to get rid of this message.Offending key in /u/xlian008/.ssh/known_hosts:2RSA host key for 135.1.35.130 has changed and you have requested strict checking.Host key verification failed.比较奇怪,于是研究了一下。
ssh会把你每个你访问过计算机的公钥(public key)都记录在~/.ssh/known_hosts。
当下次访问相同计算机时,OpenSSH会核对公钥。
如果公钥不同,OpenSSH会发出警告, 避免你受到DNS Hijack之类的攻击。
我在上面列出的情况,就是这种情况。
原因:一台主机上有多个Linux系统,会经常切换,那么这些系统使用同一ip,登录过一次后就会把ssh信息记录在本地的~/.ssh/known_hsots文件中,切换该系统后再用ssh访问这台主机就会出现冲突警告,需要手动删除修改known_hsots里面的内容。
