请教个 ssh 连接的问题，被折麽够呛

[bjlbeyond]

在公司用 mac 可以 ssh 连接上服务器，具体的配置都放在 config 文件中，目录和格式都正确。因为在公司确实连接上了。用 iterm 和 zoc 都可以连接上！

但把这个电脑带回家死活就是连接不上服务器，报 Operation timed out 、 Write failed: Broken pipe 。


尝试的方法：
1 、网上找此问题解决办法全是清一色的说在 config 文件中加上这些配置 ServerAliveInterval 120
TCPKeepAlive yes 都试了并且不管用。
2 、可我在电脑上启动虚拟机在 window 的环境下可以连接上公司的这台服务器的，证明网络是没有问题的。并且尝试连手机的 4g 网、无果
3 、在家 ping 不通公司的服务器
4 、公司服务器是没有问题的，因为同样连接不上我的阿里云服务器 ecs

求计策

-vvv 贴出来

[ibigbug]

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

[xiuc001]

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

[xiuc001]

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= =

[sagaxu]

是不是配了代理或者 vpn?

[icegreen]

应该是限制了 ip.

[bjlbeyond]

@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

[bjlbeyond]

@aec4d 怎么用？求指教

[bjlbeyond]

@sagaxu 没有

[bjlbeyond]

@xiuc001 没有限制 ip ，在家里另外一台电脑就可以连接上去

[aec4d]

ssh xxx -vvv 看全部的日志 是什么问题自然一清二楚

[bjlbeyond]

@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

[des]

@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

[shiji]

@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。。

[aec4d]

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

[aec4d]

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

[kkk330]

iterm2 不走代理的

[bjlbeyond]

@des
@shiji 不经意间给粘贴出来了，汗。。。

[bjlbeyond]

求解决办法啊

[nightYe]

公司局域网 ip 在服务器上设置白名单了吧

[bjlbeyond]

@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

[nightYe]

@bjlbeyond 你 windows 能连上吗，用什么工具连的

[bjlbeyond]

@nightYe xshell

[nightYe]

@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。

[bjlbeyond]

@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
