I am working on iptable configuration for an Automotive embedded device. I have to include all available network interfaces( also includes Virtual Interfaces which has protocol as unspec as in the below image ) in the iptable.
enter image description here



Those Virtual interfaces are added by User Applications using several protocol standards described in socket mechanism. I am not able to add these Interfaces in IPtable. If it has an ipaddress associated with it. I can add using




iptables -A INPUT/OUTPUT/FORWARD -s addr -j ACCEPT/DROP




or if i can do using -i link name option . But for this virtual interfaces even if i add in iptables like the below one




iptables -A OUPUT -i name -j DROP




but i am able to receive those packets on client application.
Please help me with this

          What visual should I use to simply compare current year value vs last year in Power BI desktop

          Image
          0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?

          Image
          up vote 1 down vote favorite I am using openpyxl for parsing .xlsm files, and pytest for testing.

When I run pytest with something like: def test_wrong_file_format(): assert check_excel(open_excel('file.xlsm')) == True I will get the warning i mentioned altought check_excel(open_excel('file.xlsm')) returns True and the test should suceed... Is there a nice way to tell the pytest that "It's not a bug it's a feature" and tests should pass even when they get this warning? Is there other way than using something like: with pytest.warns(UserWarning): ...
