Title Body

I would like to know the possible values of st column in /proc/net/tcp . I think the st column equates to STATE column from netstat(8) or ss(8) . I have managed to identify three codes: sl local_address rem_address st tx_queue rx_queue tr tm->when retrnsmt uid timeout inode 0: 0100007F:08A0 00000000:0000 0A 00000000:00000000 00:00000000 00000000 0 0 7321 1 ffff81002f449980 3000 0 0 2 -1 1: 00000000:006F 00000000:0000 0A 00000000:00000000 00:00000000 00000000 0 0 6656 1 ffff81003a30c080 3000 0 0 2 -1 2: 00000000:0272 00000000:0000 0A 00000000:00000000 00:00000000 00000000 0 0 6733 1 ffff81003a30c6c0 3000 0 0 2 -1 3: 0100007F:0277 00000000:0000 0A 00000000:00000000 00:00000000 00000000 0 0 7411 1 ffff81002f448d00 3000 0 0 2 -1 4: 0100007F:0019 00000000:0000 0A 00000000:00000000 00:00000000 00000000 0 0 7520 1 ffff81002f4486c0 3000 0 0 2 -1 5: 0100007F:089F 00000000:0000 0A 00000000:00000000 00:00000000 00000000 0 0 7339 1 ffff81002f449340 3000 0 0 2 -1 6: 0100007F:E753 0100007F:0016 01 00000000:00000000 02:000AFA92 00000000 500 0 18198 2 ffff81002f448080 204 40 20 2 -1 7: 0100007F:E752 0100007F:0016 06 00000000:00000000 03:000005EC 00000000 0 0 0 2 ffff81000805dc00 The above shows: On line sl 0: a listening port on tcp/2208. st = 0A = LISTEN On line sl 6: An established session on tcp/22. st = 01 = ESTABLISHED On line sl 7: An socket in TIME_WAIT state after ssh logout. No inode. st = 06 = TIME_WAIT Can anyone expand on this list? The proc(5) manpage is quite terse on the subject stating: <c
