    这是一个创建于 3853 天前的主题,其中的信息可能已经有所发展或是发生改变。
    前段时间 SSH 一直用的好好的,突然就连不上了,于是加 -v 看了下输出:

    Google 了一圈回来各种方法都试了,没用。
    ping 是可以 ping 通,但就是 SSH 连接不能。
    各位 V 友有遇到过吗?

    刚才排查了一下,发现貌似跟路由器有关系,我连了邻居家的 WiFi 就可以正常连上 SSH,而自家的则不行。
    我的路由器型号是 WNDRMAC 刷了 OpenWrt,会不会是路由器某处配置的原因?

    貌似是设置了多拨的原因......

    SSH是用22端口吗? 不用22端口可能被干扰.

    可以在DO临时建一台新的VPS做跳板, 用完删掉.

    其他SSH能用吗? 还是只是这台建立不了链接?

    @Tinet 目前还不清楚,我暂时取消多拨的设置后 SSH 变得正常了......
