ubuntu环境下xorp安装

 我使用的安装环境是ubuntu12.04
    按照官网安装xorp,一步一步下来，

    写/etc/xorp/config.boot

    然后执行/etc/init.d/xorp脚本， 其中xorp就是官方给的bash脚本，

    然后在、var/log/xorp 查看日志：

里面有好多warning,还有好多command没有找到，最后提示no more tasks to run

然后我google了下，发现别人也有类似的现象。

接下来执行了/usr/local/xorp/sbin/xorpsh命令：

现在这种情况老外有人回答是这样的：

Looks like it is running.  You can use 'ps' to see the xorp processes.

And, xorpsh will complain if it cannot connect to the rtr-mgr.

You can inspect routes through xorp, and you can also look at
the linux routing table from the linux command line with something
like 'ip route show'.

Thanks,
Ben

按照老外的提醒，我使用ps -ef |grep xorp 查看所有xorp的进程，结果如下：

-f        Display the uid, pid, parent pid, recent CPU usage, process start time, controling tty, elapsed CPU usage, and the associated command. 

第一列是用户ID    第二列是进程ID    第三列是父进程ID  

第四列最近cpu利用率 CMD该进程命令行输入

第五列是进程激活时间
第六列是终端是什什么  第七列是不知道   第八是进程运行的文件所在文件夹

ip route show 结果如下：

ip route 命令含义：


xorp原理还没看懂，暂时告一段落。看完文档再接着做。
