I'm poking through the code and it looks like it I've lost track. u32, etc. You should have all the dependencies in centos for the htb+fq_codel version to work. > should work, although I don't know if the CentOS 7 kernel has cake. What kernel is it? (uname -a) Probably doesn't (linux 4.19). Out of tree build and related tc mods: https://github.com/dtaht/sch_cake https://github.com/dtaht/tc-adv (or you can rebuild tc from iproute2 versions later than 4.19) Tip of tree right now has preliminary "some congestion experienced" (SCE) work in it. Don't turn it on unless you want to annoy cablelabs. You don't really need sqm-scripts for cake, it's a tc 1 liner for outbound, 4 for inbound. Regardless, you are in a world of hurt on these bandwidths, an iptables firewall rule clamping mss may help also. > > > > _______________________________________________ > Bloat mailing list > Bloat@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/bloat --=20 Dave T=C3=A4ht CTO, TekLibre, LLC http://www.teklibre.com Tel: 1-831-205-9740
