SSH在"kex_exchange_identification“上失败

Question

我试图通过ssh连接到本地计算机上运行在VMWare中的Ubuntu18.04VM。本地机器已经启动并运行了openssh服务器。

苹果默认的ssh二进制文件无法连接到VMWare中的VM，如文档中的这里。所以，我用自制软件安装了ssh，并尝试使用它。

在运行ssh时，它无法连接并输出错误：

kex_exchange_identification: write: Broken pipe

使用详细标志运行显示如下：

$ /usr/local/bin/ssh -vvv dev@[ip]
OpenSSH_8.0p1, OpenSSL 1.1.1d  10 Sep 2019
debug1: Reading configuration data /Users/[username]/.ssh/config

debug1: identity file /Users/[username]/.ssh/id_rsa type 0
debug1: identity file /Users/[username]/.ssh/id_rsa-cert type -1
kex_exchange_identification: write: Broken pipe

我的~/.ssh/config文件包含以下内容：

Host *
    ServerAliveInterval 300
    ServerAliveCountMax 2
    TCPKeepAlive no
    IPQoS=throughput
    AddKeysToAgent yes
    IgnoreUnknown UseKeychain
    UseKeychain yes
    IdentityFile ~/.ssh/id_rsa

我尝试在VM上重新启动ssh服务器，但没有结果。我还没有在网上找到任何关于kex_exchange_identification错误的信息。

感谢所有的帮助！

kex_exchange_identification: write: Broken pipe是SSH客户端在密钥交换(kex)期间断开连接的消息。

查看VMware来宾(S)上的日志，以了解SSH服务器挂起您的原因。如果它们是Unix/Linux，请在/var/log/中查找名称为messages、syslog、auth和/或authpriv的文件。
