Dear Folks, I need to delay thping packets thaI send on my ethernet port (ens33) by a patterthaI have generated using a package called Kaunetem. The delay patterworks finon the network namespace that I created to test the delay. Buiis not reflecting on the physical ethernet port. The command I used for thnamespacis as follows sudo tc qdisc add dev veth-b roonetefwmark 42 pattern data delay delaychange Thcommand I used to add thsame pattern on the ethernet port is as follows sudo tc qdisc add dev ens33 roonetepattern data delay delaychange fwmark 42 Is thersomething differenthat we have to do to insert pattern on Etherneporcompared to network namespaces?
