I wrote a small tool to manage thousand linux servers including RHEL/SUSE(a testing done on RHEL4/5/6/SUSE10) like pssh , you must make sure ssh pub key authentication and sudo setting are ready . Please see the source code below.
I will continue to make it better . It's a first version .Please keep the original writer if you forward it.
-
Build ssh key trust and work it with SUDO
-
Execute the commands and the script and capture the output to the result file on the router
3.Log audit for user and commands
4.Damn Health check
5.Subsystem deployment . ...........
....... net::openssh .......module
用perl openssh::net 写了个类似psshd的多线程工具，完善后把代码贴给大家参考， 目前我没有把ssh交互放进去，建立互信，生成ssh passprhase ,然后直接交给ssh-agent去处理。 目前基本功能: 并发跑ssh 命令 平发跑脚本 传文件到远端/远端到本地 计划加日志和审计功能 回写结果到当前目录下的result.txt
