golang ssh 包的时候思科设备可以 ssh 上去 华为不行 各位大佬指点一下

这不就是说算法不一致吗

你看看设备是不是用的 ssh1，而程序不支持 ssh1。
有些较老的设备只支持 ssh1 且不支持 ssh2。

客户端支持的 ssh 算法也太少了吧

搜索 "golang diffie-hellman-group1-sha1"
你会得到： https://github.com/golang/crypto/commit/36a967d3212260ed1abea70bb749e710e26457a

搜索 "golang diffie-hellman-group-exchange-sha1"
你会得到： https://github.com/golang/go/issues/17230

问搜索引擎显然比问 V2EX 好。

请问这个问题解决了吗

[mangwen]

@TOUJOURSER 没有 就是算法不一致 ，包不支持，换 python 操作交换机了 。
