Then I added them to `/etc/hosts` with a related hostname, e.g., `a::601 mn.h1` and `a::e02 mn.h2` Running now `sudo flent rrul -p all_scaled -6 --local-bind mn.h1 -l 60 -H mn.h2 -o rrul_hosts6.pdf -v` gives Error free output. However, I noticed a different bug when using this: If a host contains an IPv4 as well as an IPv6 address in `/etc/hosts`, flent seems to always prefer the IPv4 entry. This results in the process either failing, because it tries an irtt connection from IPv4 to IPv6 address, or the above test runs the irtt connection completely in IPv4, ignoring the `-6` argument, if both devices can be resolved to an IPv4 Maybe this is content for a separate Issue? -- You are receiving this because you are subscribed to this thread.
