In the previous issue, we discussed the tutorial on setting up PPPoE dialing in OpenWRT. In bridge mode with the optical modem, if PPPoE dialing is not configured, OpenWRT cannot access the internet properly. Tutorial on setting up PPPoE dialing in OpenWRT However, many newly installed broadband connections are set to router mode by the … Read more
<span><span>ubus</span></span> is designed with a concept similar to <span><span>d-bus</span></span> in Linux desktop systems, providing system-level bus functionality. However, compared to <span><span>d-bus</span></span>, it reduces memory usage, making it suitable for the extreme operating environments of low-performance CPUs and low memory in embedded systems. The core component is the <span><span>ubusd</span></span> daemon, which provides an interface for other … Read more
Since many people became familiar with OpenWrt relatively late, there is a common misconception that OpenWrt is synonymous with bypassing restrictions or with bypass routers.However, as a long-time user for over a decade, I have always relied on OpenWrt as my sole router at home.Today, we will share a feature that typically only appears in … Read more
