If you are using ssh to remotely go to the server for iptables setting, your ssh request will also be blocked.

"There are priorities in learning and specializing in technical fields". Everyone's value is often reflected in different aspects. We should find our own way and direction instead of blindly following the principle of postgraduate entrance examination. Industry is also the top priority of the country's development. Investment in industry can also achieve a career! " As a retired old teacher, Mr. Sun, who was supposed to live a leisurely life at home, was still able to stay far away from the "Jianghu", worried about his "monarch" and still chose to devote himself to student work.

It is very important to solve the problem of waste packaging and promote green express delivery. On the one hand, at the source, it is necessary to formulate industry standards and packaging material standards to promote more environmentally friendly packaging materials; On the other hand, it is also necessary to strengthen recycling at terminals. For a single individual, the discarded express packages may be dozens of woven bags and packing boxes, but when the whole society comes together, the number of discarded woven bags and packing boxes can reach an astonishing billions in a year. If every individual covets convenience and labor, discarding it and throwing it away at random, it will not only cause waste of resources, but also bring pressure to subsequent garbage disposal and even cause environmental pollution. It seems that the society pays the bill, but in the end it is everyone living in this society. Green life requires us to practice it together.
