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。

快速开始

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
tryssh create passwords 123456

# 用以上创建的信息尝试登陆 192.168.1.1
tryssh ssh 192.168.1.1

prune 命令

tryssh的prune命令用于测试当前已有缓存是否依然可用，如果不可用可以选择执行删除缓存，也可以不询问直接删除缓存。

prune 帮助信息

$ tryssh prune -h
Check if all current caches are available and clear the ones that are not available

Usage:
  tryssh prune [flags]

  -t, --timeout duration   SSH timeout when attempting to log in. It can be "1s" or "1m" or other duration (default 2s)

prune 使用举例

# 交互式进行缓存可用性测试
tryssh prune

# 非交互进行缓存可用性测试
tryssh prune -a

# 非交互进行缓存可用性测试，同时设置并发数为10(默认为8)，连接超时时间为5秒(默认为2秒)
tryssh prune -c 10 -t 5s -a

交互式模式下设置并发数是无效的

alias 命令

tryssh 的alias命令是用于给 已有 的缓存设置别名用的，方便在登陆或者传输文件时直接使用别名来操作

tryssh alias set host1 -t 192.168.1.1

# 取消名为"host1"的别名
tryssh alias unset host1

ssh 命令

tryssh 的ssh命令用于猜密码登陆服务器，在成功获取正确登陆信息后会缓存这些信息以便下次直接使用缓存登陆，不用重新猜密码。
