> There seems to be a fix on github... (since july 2018!) Yes, and according to the fping version you mentioned, you're running Ubuntu 18.04 Bionic from _April_ 2018. So that Ubuntu release was released before the bug was fixed upstream.
Upgrading to a more recent version of Ubuntu will fix this as this is fixed in package version 4.1-1 and all later and supported versions of Ubuntu do have at least 4.2-1. So this bug is more or less fixed—also in Ubuntu—from the general point of view. It's just not fixed in Ubuntu 18.04 Bionic. But since this neither a severe nor a security issue, chances that the fix gets backported to 18.04 are not very high. ** Bug watch added: Debian Bug tracker #891704 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=891704 ** Also affects: fping (Debian) via https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=891704 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1860323 Title: fping not working if ipv6 is disabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fping/+bug/1860323/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
