杯具的PhotonVPS

以前一直觉得PhotonVPS很高端,口碑一直很好,昨天手贱没忍住,买了一个OpenVZ来玩玩,才发现原来我错了。DD速度垃圾的一比,跟以前我用过的印度佬的SpaceRich有的一拼,好吧,看来台湾佬的东西也不能信啊!

如何判断自己的VPS是OpenVZ的还是Xen的

一般来说,VPS的虚拟化技术,有Xen、OpenVZ、Xen HVM和VMware这几种,那么,如何判断自己的VPS是基于哪种虚拟化技术的呢?

1、执行:ls /proc/命令,一般Xen的VPS,/proc目录下面会有xen的目录,openvz的会有vz目录。

2、执行:free -m命令看内存,openvz的没有swap,当然也有xen的没有swap,但是xen的是可以加的,openvz不行。

3、执行:uname -a命令,有些xen的VPS里面会显示有xen。

4、执行:ifconfig命令查看网卡,openvz的一般都是venet0:* ,xen的一般都是eth*。

5、通过VPS控制面板查看,像SolusVM、vePortal控制面板上都显示虚拟技术。

bt种子离线下载空间

网址:http://torrific.com/
简而言之,就是你提交一个BT种子,网站自动帮你把文件下载到它的服务器上,然后你再用迅雷从它的服务器上拖回来。
在谷歌搜索“bt2http”也能搜出类似的网站。

torrific已经失效了,2013.07.12介绍一个新的服务:
Dropbox网盘 + http://www.boxopus.com/ 可以实现BT离线下载。
