群晖底层也是Linux系统，但是并不是常见的发行版本，因此CentOS下的yum和debian/ubuntu下的apt都是不能用的。好在还有ipkg可以使用，但是需要自己进行安装和配置。

SSH连接并获取root权限

这里就不多说SSH了，毕竟需要装包的都应该能连上了，安装ipkg前需要sudo -i

admin@JasonNAS:~/bootstrap$ sudo -i

Password: 

root@JasonNAS:~# 

安装ipkg

然后下载ipkg的安装包，并且修改权限后运行：

root@JasonNAS:~# wget http://ipkg.nslu2-linux.org/feeds/optware/syno-i686/cross/unstable/syno-i686-bootstrap_1.2-7_i686.xsh

更新ipkg源

安装好后不需要重启，但是需要更新源：

root@JasonNAS:~# ipkg update

安装mtr试试看，没毛病：
