各位大虾，求救！！！服务器无法SSH登录！！

tsadmin

不推荐同一交换机插同一计算机的多块网卡，如果两块网卡没什么用可以作一下绑定，影响远程SSH的最主要的还是你的防火墙，两台服务器的外网IP是不是在同一子网同一VLAN下啊？

我已经在交换机上划分vlan了，而且外网是直接连到交换机通外机房提代的外线出去的，那些服务器也都在同一个子网内，同一个vlan下

确认一下其他可用访问方式，比如ping
如果可用，就是防火墙问题，否则是你路由的问题。

还有要注意两个网络是不是存在相同IP，避免访问错误的目标机器。

刚刚找到了一篇文章，照 着试了一下，结果发现我用putty可以登录，但是进去之后运行命令和敲命令有很大延迟，用SSHSecureShellClient-3.2.9就不能登录，登录事件分别是
