SSH 效劳参数装备和战略的扫描器程序

发布时间:2017-06-10 作者:电脑知识网 来源:www.sogoupc.com 字号:
 
ssh_scan 是一个面向 Linux 和 UNIX 效劳器的易用的 SSH 效劳参数装备和战略的扫描器程序,其思路来自Mozilla OpenSSH 安全攻略[1],这个攻略为 SSH 效劳参数装备供给了一个牢靠的安全战略基线的主张,如加密算法(Ciphers),报文认证信息码算法(MAC),密钥交换算法(KexAlgos)和其它。
ssh_scan 有如下优点:
它的依靠是最小化的,ssh_scan 只引入了本地 Ruby 和 BinData 来进行它的作业,没有太多的依靠。
它是可移植的,你能够在其它的项目中运用 ssh_scan 或者将它用在自动化使命[2]上。
它是易于运用的,只需求简略的将它指向一个 SSH 效劳就能够获得一个该效劳所支撑的选项和战略状况的 JSON 格式陈述。
它一起也是易于装备的,你能够创立适合你战略需求的战略。
主张阅览: 如安在 Linux 上装置装备 OpenSSH 效劳[3]
如安在 Linux 上装置 ssh_scan
 
有如下三种装置 ssh_scan 的方法:
运用 Ruby gem 来装置运转,如下:
----------- 在 Debian/Ubuntu -----------
$ sudo apt-get install rubygems
$ sudo gem install ssh_scan
----------- 在 CentOS/RHEL -----------
# yum install ruby rubygems
# gem install ssh_scan
运用docker 容器[4]来运转,如下:
# docker pull mozilla/ssh_scan
# docker run -it mozilla/ssh_scan /app/bin/ssh_scan -t github.com
运用源码装置运转,如下:
# git clone https://github.com/mozilla/ssh_scan.git
# cd ssh_scan
# gpg2 --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
# curl -sSL https://get.rvm.io | bash -s stable
# rvm install 2.3.1
# rvm use 2.3.1
# gem install bundler
# bundle install
# ./bin/ssh_scan
如安在 Linux 上运用 ssh_scan
 
运用 ssh_scan 的语法如下:
$ ssh_scan -t ip地址
$ ssh_scan -t 主机名
举个例子来扫描 192.168.43.198 这台效劳器的 SSH 装备和战略,键入:
$ ssh_scan -t 192.168.43.198
留意你一起也能够像下方展现的给 -t 选项传入一个[IP地址/地址段/主机名]:
$ ssh_scan -t 192.168.43.198,200,205
$ ssh_scan -t test.tecmint.lan
输出示例:
I, [2017-05-09T10:36:17.913644 #7145] INFO -- : You're using the latest version of ssh_scan 0.0.19

你能够运用 -p 选项来指定不同的端口,-L 选项来敞开日志记录配合 -V 选项来指定日志等级:
$ ssh_scan -t 192.168.43.198 -p 22222 -L ssh-scan.log -V INFO
另外,能够运用 -P 或 --policy 选项来指定一个战略文件(默许是 Mozilla Modern)(LCTT 译注:这里的 Modern 也许指的是 https://wiki.mozilla.org/Security/Server_Side_TLS 中说到的 Modern compatibility ):
$ ssh_scan -t 192.168.43.198 -L ssh-scan.log -V INFO -P /path/to/custom/policy/file
ssh_scan 运用帮助与其它示例:
$ ssh_scan -h
