(#163) Date: Thu, 06 Jun 2019 07:43:00 -0700 [thread overview] Message-ID: <tohojo/flent/issues/163/499524417@github.com> (raw) In-Reply-To: <tohojo/flent/issues/163@github.com> [-- Attachment #1.1: Type: text/plain, Size: 2494 bytes --] Ok, there is a difference there (below, sudo version contains pid at end of ESTAB line). Running flent with sudo works even though I didn't used to need to do that on older Ubuntus. It's a fine workaround for now, only in addition, ss with my custom kernel doesn't show TCP RTT or a lot of other stats at all (third output below), so that could either be some needed kernel config or something else, so I'm off to figure out what that is. Thanks... :) ``` $ ss -tipn State Recv-Q Send-Q Local Address:Port Peer Address:Port ESTAB 0 0 10.72.0.37:22 10.72.0.64:61418 cubic wscale:5,7 rto:204 rtt:0.34/0.071 ato:80 mss:1448 pmtu:1500 rcvmss:1392 advmss:1448 cwnd:10 bytes_acked:13057 bytes_received:6621 segs_out:130 segs_in:230 data_segs_out:123 data_segs_in:105 send 340.7Mbps lastsnd:108364 lastrcv:108420 lastack:108364 pacing_rate 681.4Mbps delivery_rate 139.6Mbps app_limited busy:12ms rcv_space:14600 rcv_ssthresh:64076 minrtt:0.083 ``` ``` $ uname -a Linux rey 5.0.0-16-generic #17-Ubuntu SMP Wed May 15 10:52:21 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux $ sudo ss -tipn State Recv-Q Send-Q Local Address:Port Peer Address:Port ESTAB 0 0 10.72.0.37:22 10.72.0.64:61418 users:(("sshd",pid=9397,fd=3),("sshd",pid=9360,fd=3)) cubic wscale:5,7 rto:204 rtt:0.34/0.071 ato:80 mss:1448 pmtu:1500 rcvmss:1392 advmss:1448 cwnd:10 bytes_acked:13057 bytes_received:6621 segs_out:130 segs_in:230 data_segs_out:123 data_segs_in:105 send 340.7Mbps lastsnd:119880 lastrcv:119936 lastack:119880 pacing_rate 681.4Mbps delivery_rate 139.6Mbps app_limited busy:12ms rcv_space:14600 rcv_ssthresh:64076 minrtt:0.083 ``` ``` $ uname -a Linux rey 5.1.0-rc2+ #63 SMP Mon Jun 3 17:45:55 CEST 2019 x86_64 x86_64 x86_64 GNU/Linux $ sudo ss -tipn State Recv-Q Send-Q Local Address:Port Peer Address:Port ESTAB 0 0 10.72.0.36:22 10.72.0.64:61660 users:(("sshd",pid=4006,fd=3),("sshd",pid=3937,fd=3)) rto:0.2 ato:0.11 qack:8 cwnd:10 reordering:0 ``` -- You are receiving this because you are subscribed to this thread.
