vs code 又搞幺蛾子了？ ssh remote 无法远程连接带中文名的主机了呢？

[GoodRui]

没注意从哪天，反正是最近 2 、3 周开始，使用 ssh remote 远程的时候无法连接 host 名中有中文字符的主机了呢？用 Mac 和 Windows 的测试都不行了... 搜了下也没人讨论，是我个人问题吗？

[march1993]

日志贴上来看一下

[GoodRui]

多次尝试了下，发现是 Mac 的连不了，Windows 的可以正常连...

看中间 `stderr> hostname contains invalid characters`

ssh config 配置文件中主机的配置

```
Host 测试.63
User root
HostName 172.16.111.63
Port 22
```

我反复测试了，只要 `Host` 中有中文字符，就会报错。以前是没问题的，然后刚才用 Windows 机器测了几个也没问题。

[march1993]

单独跑 `ssh -v -T -D 58228 -o ConnectTimeout=15 测试.63` 呢

[GoodRui]

@march1993 感谢兄弟回复

我发现是我的 mac 连接的时候提示 `hostname contains invalid characters` 了...
这是咋整的呢...

[march1993]

@GoodRui 改 PATH 环境变量，用自己编译的 ssh 顶掉系统自带的

[GoodRui]

@march1993 感谢老哥，我发到 macOS 区了，https://www.v2ex.com/t/1026819 ，是最近 openssh 升级漏洞导致的，从 9.6p1 开始禁止 hostname 中使用特殊字符了。用 homebrew 安装了 openssh 9.5p1 问题解决了。纠结以后怎么办。
