Hi, I remember that this worked in 1.9.x, but somehow: $dnsdist -c > showVersion() dnsdist 2.0.1 > setWeightedBalancingFactor(0) setWeightedBalancingFactor cannot be used at runtime! Curiously enough I found a regession test for this in regression-tests.dnsdist/test_Routing.py, so..bug or feature? cheers Holger
