Hi all, I am trying to disable rack to see 3dupacks in action during loss-detection but based on the pcap, I see that it's still trigger loss-recovery on the first SACK (as if RACK is still enabled/active).
Here is what I did to disable rack: net.ipv4.tcp_recovery = 0 I've also disabled metrics: net.ipv4.tcp_no_metrics_save = 1 And also flushed existing entries with 'ip tcp_metrics flush' just to be on a safer side. Not really relevant here but I've also switched to reno. I am on: 4.10.0-33-generic pcap: https://transfer.sh/mfoiN/reno_no_rack.pcap What am I missing? I can provide any additional info. Cheers, Hiren
