Episode 42 of Linux Server Admin with Fexingo dives into diagnosing and fixing packet loss on Linux servers. Lucas and Luna explore practical tools like ping, mtr, tcpdump, and ethtool to pinpoint whether the issue is in the network interface, cable, switch, or kernel buffers. They walk through a real-world scenario where a jammed network cable on a Ubuntu server caused 2.3% packet loss, and show how to isolate and resolve it step by step. They also cover checking for dropped packets with netstat -s and interface statistics, and discuss when to involve your network team versus fixing it yourself. By the end, you'll know how to systematically troubleshoot packet loss without guessing.
