[SOLVED]ss command from core/iproute2 missing internal TCP information

Hello,

I am using the following command:

ss -Hnti state established

I am not seeing the internal TCP information that I would expect when I pass in the

-i or --info

From the man page from the man page: https://man.archlinux.org/man/ss.8.en#i, I expect to see something like this but again, it is missing on my ArchLinux installations.

	 cubic wscale:7,7 rto:213 rtt:12.921/2.86 ato:40 mss:1348 rcvmss:590 advmss:1448 cwnd:49 ssthresh:47 bytes_acked:223632 bytes_received:1838 segs_out:178 segs_in:88 send 40.9Mbps lastsnd:2802 lastrcv:2802 lastack:2792 pacing_rate 81.8Mbps retrans:0/1 reordering:4 rcv_space:28960

May someone help me get the command to show the internal TCP information? Do I need to enable something in my sysctl for further TCP debugging?

Thanks!
-Adam
