问题现象:
1、原来用Xshell连着的窗口能正常操作
2、重新打开新的窗口却提示:
Connecting to 192.168.36.61:22...
Connection established.
To escape to local shell, press 'Ctrl+Alt+]'.

找了好久都不知道为什么会这样,然后网上搜到一篇文章,找到了灵感,跟我的情况类似

问题源头:/etc/security/limits.conf
因为我后台部署elasticsearch 会去自动修改/etc/security/limits.conf中的配置,而最后一次部署过程中出现问题,删除了/etc/security/limits.conf文件,导致新的shell再也无法连接上。
