tcconfig kali

[sanhar]

I am newbie to network and firewall system.

I installed kali linux latest version.
it contains python3.7.2+

tcconfig was installed with pip3

When I run ' tcset ens3 --delay 10sec --rate 1bps --network <remote_ip_address> --direction incoming ' on console, I got errors as following.

[ERROR] tcconfig: command execution failed
command=/usr/sbin/tc class add dev ifb5634 parent 1602: classid 1602:2 htb rate 0.001Kbit ceil 0.001Kbit burst 1.25e-05KB cburst 1.25e-05KB
stderr="rate" is required.

[ERROR] tcconfig: command execution failed
command=/usr/sbin/tc qdisc add dev ifb5634 parent 1602:2 handle 2bb2: netem delay 10sec
stderr=Error: Specified class not found.

Could someone explain why the errors mean and how to fix it ?

@sanhar
Thank you for your report.

Could you try to set 8bps or greater value to --rate option?
The minimum valid rate of tc is 8bps according to the tc source code:

I had fixed the minimum bandwidth rate validation at tcconfig 0.21.8.
