Neooostef Posted 19 hours ago Posted 19 hours ago Hello I encounter a problem when I run the TCPDUMP command Here is the error eth0: SIOCETHTOOL(ETHTOOL_GLINK) ioctl failed: Device or resource busy Work like a charm with Radxa Debian OS, but on two Armbian same problem. Someone knows why ? Thanks 0 Quote
Werner Posted 19 hours ago Posted 19 hours ago Providing logs with armbianmonitor -u helps with troubleshooting and significantly raises chances that issue gets addressed. 0 Quote

Werner Posted 8 hours ago Posted 8 hours ago You can force output to terminal when using -U instead of -u with armbianmonitor. Copy everything to a paste service like paste.debian.net or paste.armbian.de when paste.armbian.com doesn't cut it 0 Quote
