An in-depth understanding of Linux Network Technology-Virtual Device initialization summary and a deep understanding of linuxOverview a virtual device is an abstraction built on one or more real devices. There are many to many mappings between virtual devices and real devices, but not all combinations can be defined or supported by the kernel.The following lists some common Virtual Devices: Bonding // bindi

Some Linux network tools you may not know If you want to monitor the network on your system, it is very practical to use the command line tool. For Linux users, there are many ready-made tools available, such as nethogs, ntopng, nload, iftop, iptraf, bmon, slurm, tcptrack, cbm, netwatch, collectl, trafshow, cacti, ethe
