MJJ Intel

Recently tinkered with a provider called Incudal, quite interesting. If you are also an MJJ with a bunch of idle machines, you can pick up a couple of toy boxes to play with. This provider has pushed prices ridiculously low. Aside from some dirt-cheap landing boxes, the coolest feature is: it allows you to list your idle servers (or nodes) on their platform for sale. Essentially you provide the server and they provide the platform, one-click VM dividing, becoming your own boss to recoup costs—pretty breaking the mold. ...

In previous articles, I introduced how to host domains on Cloudflare and use CF CDN for free. This time, I’m demonstrating one of my favorite features: Email Routing. With just one domain, you can have your own domain email and create infinite sub-emails for use. You don’t need to set up a complex mail server. As long as you have a domain hosted on Cloudflare, you can use any prefix to register accounts. All emails will be automatically forwarded to your designated primary email address, making it very convenient to receive verification codes. ...

Introduction This article compiles a Standard Operating Procedure (SOP) for Alpine Linux, as a companion to Setting Up a New Linux Server. Install Alpine Linux Install via Custom ISO If your provider (e.g., Netcup, BuyVM, BeroHost) supports uploading customized ISOs, we recommend using the VIRTUAL edition of Alpine Linux, which is stripped and optimized for KVM virtualization. One-click DD Reinstall Script For providers that do not support mounting custom ISOs, you can use a one-click DD reinstall script: ...

Introduction Recently, the Netherlands route has been relaxed, and registration can be completed without video verification. If your English is not strong, you can try the Netherlands region first. N26 has been popular for quite a while, so I finally followed the crowd and opened one myself. Founded in 2013, N26 is a licensed German bank and a fully regulated European digital bank. As of 2021, N26 had more than 5 million customers and operated in more than 25 countries and regions. Eligible deposits are protected up to EUR 100,000. N26 offers both personal and business accounts, with four account tiers that differ in monthly fee and benefits. It provides two kinds of debit cards and supports mobile payments such as Apple Pay and Google Pay, but it does not offer credit cards. ...

Many people come into contact with proxies, VPNs, and remote desktops due to legitimate needs such as cross-border office work, overseas access, traveling online, privacy protection, and corporate compliance access. However, platform risk control systems (TikTok/PayPal/Facebook, etc.) often view “abnormal networks, abnormal devices, abnormal behavior” as risk signals, triggering captchas, rate limits, or even freezes—highly common on AI/financial services. Most people are completely confused about proxy detection: “I have connected to a ladder (VPN), shouldn’t the website see that my IP belongs to certain regions like the US? Why can they still detect that I am using a ladder?” Actually, this is a quite complex topic filled with technicalities and controversies. Today, I’ll briefly explain the most commonly used proxy detection methods and shielding measures in our practices to give some proxy detection science. This article will not heavily analyze distinct technologies; like other posts on this blog, this article focuses on science popularization for beginners. Technical papers will be placed in the reference section at the end. ...

For Quick-Fix, Jump directly to the ip neigh replace section Diagnostic Process: First, check routing and neighbors with ip route and ip neigh 1 2 3 # ip neigh xx.xx.xx.2 dev eth0 FAILED xx.xx.xx.1 dev eth0 INCOMPLETE Resolution for the INCOMPLETE issue (ignore the FAILED one). Checking results with tcpdump shows: When replying, a large number of ARP, Request who-has xx.xx.xx.1 are sent. Conclusion: The gateway is “Playing Dead”: The key point is that no one is responding to this ARP request. Because your VPS cannot get the MAC address of the gateway xx.xx.xx.1, it doesn’t know who to throw the reply packet to, causing the packets to be dropped inside your network card. ...
