Mobile free one month cloud server CentOS 6.5! I don't know when mobile started to be a server. I learned today that I set up a platform. There is no too much experience. The detailed configuration is shown in the figure. The activity is up to November 30, 2016. Activity address: http://ecloud.10086.cn/market/registgift The official said that there are 100 sets every day, starting at 10 o'clock. I registered about 6:00 p.m. and there are not many friends who should play. After all, the bandwidth is only 2m! It's not good to use it myself. I built a Ss to practice Linux. Originally, I wanted to build ports 137 and 138, but the SS libev version does not support multi ports. Instead, python version found that port 137 could not be used. If you know how to share the moving things, you can't be used as a ladder. The expiration date of 11 / 28 server is "112.33.16.246", "server"_ port":9527,"local_ address":"127.0.0.1","local_ port":1080,"password":"123456789","timeout":300,"method":"aes-256-cfb","fast_ open":fa2016lse -
