TCP/IP output query

[dantrack]

Hi,

when I run netstat -s I get a whole listing of different statistics
on udp/tcp. what I would like is to be able to understand those terms
e.g. TCPLossFailures and link them with the appropriate TCP/IP terminology. There must
be some refernce guide somewhere that shows what these fields mean or
what they are tracking, can somone please help me with finding this?

Thanks
Dan

Hi Dantrack,
I'm not sure if this helps, but most of the stuff from "netstat -s" comes from /proc/net/netstat. You can try the kernel Documentation for more info on what it means.

IMO you just need to know basic TCP/IP to make sense off it. e.g -

Tcp:
141401 active connections openings -- or SYN connection
0 passive connection openings -- ??
35 failed connection attempts -- SYN send by no response from server.
66530 connection resets received -- SYN RST packet
39 connections established -- successful TCP connection
1854794 segments received -- No. of segmented packets revived
2006559 segments send out -- No. of segmented packets sent out
3477 segments retransmited -- Well, you know
0 bad segments received -- Wrong packet assembly (like various attacks).
264909 resets sent -- SYN RST packet
