Ping decimal places
Open, LowPublicBUG


VyOS seem to suffer from iputils bug that sometimes displays 2 decimal places in ping roundrip time.

Quite likely older versions are affected as well.

$ ping 1.1
PING 1.1 ( 56(84) bytes of data.

I don't seem to see the obvious problem (maybe I don't understand what you're referring to), assuming there is a problem and this is also an issue introduced by third party system components, maybe you should go upstream with feedback

Viacheslav changed Why the issue appeared? from Will be filled on close to Issues in third-party code.
