1. A Huge Pitfall Encountered When Logging into Telegram on a New iPad Recently, considering I no longer needed mobile work, I sold my unused M1 MacBook Pro and iPad mini 6 on Zhuanzhuan (a second-hand marketplace app): Then, I added some money and exchanged them for cellular versions with national subsidies…
Understanding iptables: What you really need to master is not the rules, but the flow of data packets.
1. Introduction Actually, I've wanted to write an article about iptables for a long time.
