The largest hosting provider on TG, 50KVM, has gone bankrupt! VPSs originally priced at over 100 or 200 yuan are now all 2 yuan! All for 2 yuan! (Not really) The Beginning On Sunday, April 1st around midnight, lying in bed watching the latest episode of "National Team" Telegram notification pops up: 50KVM released an April Fools' discount: Since I finished watching "National Team," might as well try entering these emojis First Attempt Tried inputting emojis using macOS input method – turned out impractical since I couldn't recognize what these emojis were Googled "emoji list" Found an emoji reference site Emoji List Wait, macOS emojis look completely different from those in the image Took some guesses (After 5 attempts) Still need to identify the emoji font....
Configuring Hurricane Electric IPv6 Tunnel on OpenVZ, Enabling the Entire Address Pool and Using it Alongside Native IPv6
AlphaRacks is a cost-effective hosting provider, offering VPS with 1 CPU, 512MB RAM, and 10GB storage for just $9.9/year. However, this provider is quite stingy with IPv6 addresses, requiring users to justify their need for IPv6. It's said they provide up to 20 addresses? But they may not allocate the full amount. For example, when I explained I needed IPv6 to serve IPv6-only users, the provider replied: We've added 1 IPv6 address to your VPS. A single IPv6 address is insufficient for my needs. Fortunately, Hurricane Electric in the US offers IPv6 tunneling services , providing each user with 5 tunnels. Each tunnel includes a /64 address pool, and users can instantly activate a /48 address pool with one click. Despite this generous service, using it on OpenVZ VPS requires extra effort....
Host1Free Strikes Again to Prevent VPS Idling: Monthly Renewal Required
Eight months ago, Host1Free cleaned up a large number of idle users by shutting down their VPSes . Now, H1F has introduced another tough measure: requiring users to enter a verification code monthly to renew their service, or risk VPS deletion. Two weeks after each renewal, you'll receive an email for the next month's renewal. You must complete the renewal within two weeks of receiving the email, otherwise your VPS will be suspended. If you fail to renew within an additional week, your data will be permanently deleted. Additionally, this notification email was once again found in the spam folder......
Host1Free Recently Upgraded Network Infrastructure, Changing VPS IP
Dear Host1Free User Lan Tian, We would like to announce that due to changes in our network infrastructure we will be changing current IP address of your free VPS server 5.175.206.68 to the new one 5.175.156.249. In order to allow you to prepare for this event we added IP address 5.175.206.68 as main IP address and old 5.175.156.249 IP left as additional to your free VPS server. Next Wednesday (2013-06-13) old IP address will be removed. Please make sure to update your servers settings, DNS settings and etc. accordingly to avoid any inconience after old IP(5.175.156.249) address removal at Wednesday."

Porting Bad Apple to Telnet and Successfully Screening It
Today, after tinkering for half a day, I successfully ported Bad Apple to my VPS's Telnet service using the command-line animation version I published earlier. To view it yourself: telnet xuyh0120.tk or telnet 5.175.156.249 Round 1. Porting to SSH Since I originally promised a classmate I'd implement this via SSH, I started there. First, I uploaded Bad Apple to my VPS at /opt/badapple , which contains two files: badapple and badapple.in (the resource file with a modified extension). useradd badapple passwd badapple # 密码我设的badapple su badapple # 切换过去 chsh # 输入/opt/badapple/badapple exit When testing via SSH, I encountered Error 2 (resource file not found). I recompiled locally (the VPS lacks FPC), changed paths from relative to absolute, re-uploaded,...
W3 Total Cache Implements Memory Caching
W3 Total Cache uses disk-based caching by default. For shared hosting users, this may be the only option available. However, VPS users have significantly more flexibility, especially when using VPS providers with efficient overselling techniques (Host1Free?) where disk speeds are relatively slow. In such cases, you can leverage your surplus memory for caching. I've set up three WordPress test sites on SAE, OpenShift, and Host1Free VPS respectively. Among these, only the VPS allows for full customization, making it our focus today. (Note: SAE's file read/write restrictions prevent W3 Total Cache from even saving configurations.) Additionally, W3TC supports PHP Opcode caching solutions (such as Zend Optimizer (not Zend Guard), eAccelerator, XCache, APC, etc.)...
Using Certificates to Authenticate Linux Remote Login
Most people use passwords to log into a Linux shell remotely. Not only is it tedious, but if you use the same password everywhere and encounter an incident like the CSDN 6 million password leak, your VPS is essentially compromised. Therefore, we can replace passwords with a more convenient and secure method: RSA-encrypted certificate files. First, we need to generate a certificate. cd ~/.ssh ssh-keygen -t rsa At this point, your .ssh directory should contain two new files: id_rsa.pub and id_rsa . The latter is your private key—keep it secure—while the former is your public key, which can be shared publicly. Next, we'll configure our VPS. Upload your id_rsa.pub to the server's ~/.ssh directory using FileZilla or WinSCP, and rename it to authorized_keys ....
Host1Free VPS Memory Usage Optimization
PS: After publishing the article for the first time, I realized I forgot to configure the connection between nginx and php5-fpm. When I tried to connect to my VPS to check the settings, I opened the terminal, pressed the up arrow and Enter, only to discover my last command was "exit"... PS2: Folks using port 22 on VPS should be cautious – you might get disconnected mid-command. Switch to another port like 2222. (So 2-ish) PS3: Today I set up a Debian 6 test environment on VirtualBox and discovered Lighttpd has plugin functionality... Revised accordingly. For a VPS, resources like CPU and disk space are usually sufficient for running a personal blog like mine. The real headache is insufficient memory....
Host1Free Checks If All Users Are Using Their VPS
Host1Free's free VPS campaign has been running for quite some time. They've deployed over 30 servers, allocating a total of 30,000 VPS instances (severe overselling... but it's free, so we have to bear with it). This attracted a massive number of user registrations, and most importantly, the official service doesn't discriminate against users from China. However, Chinese users have a characteristic: after getting the VPS, they play around with it until they get bored, then abandon it. Or if they obtain other VPS services (like EC2 or VPS.me, which was available months ago), they stop using it entirely. But Host1Free is quite diligent overall – whenever a server goes down, they restart all VPS instances. Consequently, those unused VPSes, each with 128MB RAM + 640MB Swap, waste resources....
Host1Free VPS Application Successful
I saw the news about Host1Free VPS online long ago and wanted to apply. However, when I tried from my home computer, it showed "Only registrations from unique IPs allowed." Then I used Go^_^Agent, submitted successfully, but got rejected. After repeated attempts, I wasted Gmail + Hotmail 2 + QQ 2 accounts... Later I told imbushuo about it. He applied directly from the school computer lab and succeeded. Just like that... Eventually I realized it was a dynamic IP issue—applications from dynamic IPs would fail. This time I applied from my dad's office and succeeded. 128MB RAM, 10GB hard drive—only good for tinkering. Probably can't even handle WordPress. IP: 94.249.250....
