请教个 ssh 连接的问题，被折麽够呛

-vvv 贴出来

Write failed: Broken pipe 这不是已经连上了么？延迟太大了吧。

服务器限制了 ip 地址吧，只有公司的 ip 地址可以连，你在家里 ip 和公司不一样的

如果工作需要就找运维，如果不想麻烦运维，那么把电脑放在公司，然后在这个电脑上开一个 ngrok ，你就可以通过 ngrok 连接公司的那台电脑，然后再通过公司那台电脑就可以连公司的服务器了= =

是不是配了代理或者 vpn?

应该是限制了 ip.

@icegreen 我在家用这个电脑的里的虚拟机是可以连上公司服务器的，而且用另外的 windows 电脑也可以连上

@aec4d 怎么用？求指教

@sagaxu 没有

@xiuc001 没有限制 ip ，在家里另外一台电脑就可以连接上去

ssh xxx -vvv 看全部的日志 是什么问题自然一清二楚

@aec4d 打印出来很多、显示密码认证已经成功了，但是不知道为啥连不上

@bjlbeyond 记得把日志中的 ip 去掉啊，另外 root 用户+密码登陆？？
日志没看出来什么有用的东西，建议你去看看服务器日志

@Livid 是不是要帮这位隐藏一下服务器 IP.. 不经意之间就粘贴出来了。。

http://serverfault.com/questions/692026/cant-complete-ssh-connection-after-successfully-exchanging-keys-to-ubuntu-from

看起来很复杂啊...你可以试试按照上面的做法，设置通过代理连接看看 比如你本机开了一个 1080 的端口是 socks5 代理,试一下配置添加 ProxyCommand /usr/bin/nc -X 5 -x localhost:1080 %h %p

忽略我上面说的代理 直接测试 ProxyCommand /usr/bin/nc %h %p

iterm2 不走代理的

@des
@shiji 不经意间给粘贴出来了，汗。。。

求解决办法啊

公司局域网 ip 在服务器上设置白名单了吧

@nightYe 我回家后用其他电脑是可以连接上的，而且我同样用 mac 连不上自己的阿里云服务器

@bjlbeyond 你 windows 能连上吗，用什么工具连的

@nightYe xshell

@bjlbeyond 有尝试过清理 mac 上的 ssh key 吗，以前有遇到过类似的这种现象，不过当时是服务器重装造成的，清除本地的 ssh key 缓存重新连接即可。你可以尝试一下。

@nightYe 自从买回这个电脑，在家就没连成功过公司的电脑，在公司这台电脑能正常连接
