keepalived就是电脑使用vrrpd

家里添加一台笔记本后，台式电脑的运行时间就少了。但是不能让白白运行啊，要善于下载！所以mldonkey也拷贝到笔记本上了。 但是之前的port forward做在了台式机上了，没有port forward当然下载会慢，所以用keepalived的方法来解决。让台式机和笔记本共用一个virtual ip。

安装方法

sudo apt-get install keepalived
sudo cp /usr/share/doc/keepalived/samples/keepalived.conf.sample /etc/keepalived/keepalived.conf

priority 99 for laptop

! Configuration File for keepalived

   }
   notification_email_from Alexandre.Cassen@firewall.loc

台式机上使用的是100

查看

除了syslog外，可以使用ip a来查看
