跨平台命令行ssh终端工具tryssh详解

tryssh

tryssh 是一个拥有猜密码功能的命令行ssh终端工具。

tryssh可以非常方便在命令行中通过ssh协议连接服务器，也可以非常方便地管理服务器的登陆账号密码等信息。

tryssh拥有跨平台的能力，可以在多种操作系统上正常工作。

tryssh github仓库地址

注意：因tryssh有并发猜密码的功能，所以tryssh理论上拥有暴力破解服务器密码的能力。不建议使用tryssh去做类似事情。

引用自github仓库中README的例子

# 创建一个名为 testuser 的备选用户
tryssh create users testuser

# 创建备选端口号 22
tryssh create ports 22

# 创建一个备选密码
