Transmission状态提示错误：UDP Failed to set receive/send buffer

在VPS上使用transmission-daemon时出现以下错误

root@n1:/usr/bin# service transmission-daemon status

解决方法：

1.编辑文件

/etc/sysctl.conf

2.在文件末尾添加如下内容，示例接收缓冲区设置为16MB，将发送缓冲区设置为4MB，可以自行修改

net.core.rmem_max = 16777216
net.core.wmem_max = 4194304

3.生效

sysctl -p

重新执行命令，查看是否仍有错误提示。
