My log file is: Dec 13 21:54:25 FreeBSD kernel: tcp_output: 202.119.117.246 inc sockbuf, old 33304, new 41496, sb_cc 30328, snd_wnd 65160, sendwnd 20308 Dec 13 21:54:25 FreeBSD kernel: tcp_output: 202.119.117.246 inc sockbuf, old 41496, new 49688, sb_cc 39680, snd_wnd 66608, sendwnd 20272 Dec 13 21:54:25 FreeBSD kernel: tcp_output: 202.119.117.246 inc sockbuf, old 49688, new 57880, sb_cc 46840, snd_wnd 65160, sendwnd 24616 Dec 13 21:54:25 FreeBSD kernel: tcp_output: 202.119.117.246 inc sockbuf, old 57880, new 66072, sb_cc 54536, snd_wnd 65160, sendwnd 30408 Dec 13 21:54:25 FreeBSD kernel: tcp_output: 202.119.117.246 inc sockbuf, old 66072, new 74264, sb_cc 63848, snd_wnd 65160, sendwnd 33304 Dec 13 21:54:25 FreeBSD kernel: tcp_output: 202.119.117.246 inc sockbuf, old 74264, new 82456, sb_cc 71544, snd_wnd 65160, sendwnd 39096 Dec 13 21:54:25 FreeBSD kernel: tcp_output: 202.119.117.246 inc sockbuf, old 82456, new 90648, sb_cc 73944, snd_wnd 66608, sendwnd 43440 Dec 13 21:55:58 FreeBSD kernel: tcp_output: 202.119.117.245 inc sockbuf, old 33304, new 41496, sb_cc 29818, snd_wnd 64128, sendwnd 15461 Dec 13 21:58:13 FreeBSD kernel: tcp_output: 202.119.117.45 inc sockbuf, old 33580, new 41772, sb_cc 31672, snd_wnd 65535, sendwnd 17520 Dec 13 21:58:13 FreeBSD kernel: tcp_output: 202.119.117.45 inc sockbuf, old 41772, new 49964, sb_cc 37592, snd_wnd 65535, sendwnd 21900 Dec 13 21:58:13 FreeBSD kernel: tcp_output: 202.119.117.45 inc sockbuf, old 49964, new 58156, sb_cc 44324, snd_wnd 65535, sendwnd 23360 Dec 13 21:58:13 FreeBSD kernel: tcp_output: 202.119.117.45 inc sockbuf, old 58156, new 66348, sb_cc 53408, snd_wnd 65535, sendwnd 27740 Dec 13 21:58:13 FreeBSD kernel: tcp_output: 202.119.117.45 inc sockbuf, old 66348, new 74540, sb_cc 62492, snd_wnd 65535, sendwnd 32120 Dec 13 21:58:13 FreeBSD kernel: tcp_output: 202.119.117.45 inc sockbuf, old 74540, new 82732, sb_cc 70116, snd_wnd 65535, sendwnd 37960 Dec 13 21:59:29 FreeBSD kernel: tcp_output: 202.119.117.245 inc sockbuf, old 41496, new 49688, sb_cc 36934, snd_wnd 64128, sendwnd 19101 Dec 13 21:59:29 FreeBSD kernel: tcp_output: 202.119.117.245 inc sockbuf, old 49688, new 57880, sb_cc 44222, snd_wnd 69888, sendwnd 22976 And 117.45 is XP, 117.245 is Debian, 117.246 is FreeBSD-6-Stable.
