I set this up on a home network. It actually restricted speed (egress) to a target NOT named as CIDR1 or CIDR2. I found that I removed the "default 30" from this line in the script: $TC qdisc add dev $IF root handle 1: htb #default 30 removed After this, the non CIDR host speed test (via iperf3) had the expected unrestricted bandwidth results. So I then tried to find documentation on HTB and what "Default 30" was supposed to mean. Anyone have a clue where to find the answer? Great video and thanks for sharing. It was never detailed as mentioned in the vid what "default 30" meant. (I still learned a bunch ! :-) Thanks) Edit.... I found that 'default' in HTB assigns all traffic not defined (filtered) to a flowid (30 in this case). Hope this helps someone, somewhere, sometime...

Thanks for this detailed and yet well explained video. My interface is named "enp0s3" and changed it in the script as required. But when i run it, I get the error "Cannot find device "enp0s3" ". I am able to send traffic via iperf. So the listening and transmission works well. What could be the reason for the cannot find device error ?

hello could you send example for simulate slow speed like GPRS or dialup and correct latency settings with tc because, i try it, but not working on inbound traffic just outbound, i need to working both inbound and outbound.

I have a question. How to attach two network adapters a wifi card and ethernet port to one class in order to be shaped as singular device? Basically I want them both share one bandwidth for download speed with one qdisc which is cake in order to remove ping spikes.

Hi, thanx for a good video. I've been looking for a (c++) api to control tc from my own application, but not found any good hits. Anyone with a good hint? The use case is that I dynamically want to limit bandwidth for e.g. ftp on port 21 based on criteria not possible to detect in the network traffic itself.

Hi Octetz Nice videos I need some clarifications , in this example , you are adding qdisc first tc qdisc add dev eth0 root handle 1:0 then you are creating the class , and then filter. Can we add filter to the existing qdisc or always we need to create new qdisc and then attach filter to it , in my case , in my system, i just listed the qdiscs , it was showing something like below tc qdiscs show qdisc mq 0: dev eth0 root qdisc pfifo_fast 0: dev eth0 parent :1 bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1 1 1 If i want to add a filter which qdisc i should select (there are 2 qdiscs available above), i want to add filters to exclude some of the ports , what should be the filter commands ? Can you please help me on this ?
