Which OS, and which command exactly? Because on those systems that I have access to netstat outputs nice headers that should be easy to understand if you know a bit about networking.
I'm using Mac OS X Leopard. The output looks something like this (shortened for brevity's sake):
I don't know what any of this means. I'm not much of a networking person, and I only know a little bit about TCP/IP (like what DNS and DHCP are), so this doesn't make much sense to me.
Dear Experts,
I put below command-
could you please describe the outputs column-
let me describe some them-
col_1: (10.131.60.48.55880) The IP address of the local computer and the port number being used for this particular connection appear in the Local Address column.

Hi,
Does anyone know why I get a different output when using "netstat -a" or "netstat -an" ??
# netstat -a | grep ts15r135
tcp 0 0 nbsol152.62736 ts15r135.23211 ESTABLISHED
# netstat -an | grep 172.23.160.78
tcp 0 0 135.246.39.152.51954 ... (4 Replies)
hi all,
when I run-
wcars1j5#netstat -an | grep 8090
127.0.0.1.8090 *.* 0 0 49152 0 LISTEN
wcars1j5#
1. does this mean that no one is connected to this port?

I have a TCPIP server application (a Vendor package) which by default allows 10 connections. It provides a parameter to allow us to increase the maximum allowable connections in case it is needed. Intermittently this application is failing with maximum number of connections reached even when there... (1 Reply)
Hi,
I'm trying to figure out how much traffic has been generated and received from netstat -s output (using Linux). I can see the output shows packet counts and Octet values, how would I correctly calculate how much traffic in and how much out?
My output below:

Hi,
I have old SCO O/S. System keeps crashing. I made lot of changes to kernel but so for nothing helped. I wrote a script which takes netstat -an output every one minute. I saw some thing right before the system crashed. Not sure if this means anything..

Hi Team,
Below is the output of netstat -an | grep 1533

Hi All,
I am trying to collect the listen ports info from netstat command in centos 7
From that info i am trying to collect all the foreign address IP for those ports.
I am using below script to do the same.

ntp.drift(4) Kernel Interfaces Manual ntp.drift(4)NAME
ntp.drift - Network Time Protocol (NTP) drift file
DESCRIPTION
When the NTP daemon (xntpd) is first started, it computes the error in the intrinsic frequency of the clock on the computer it is running
on. This process usually takes about a day or two after the daemon is started to compute a good estimate of this (and it needs a good
estimate to synchronize closely to its server). Once the initial value is computed, it will change only by relatively small amounts during
the course of continued operation.
The driftfile declaration should always be included in the ntp.conf file. This provides xntpd with complete path name to a file in which
it can store the current value of the frequency error. That way, if the daemon is stopped and restarted, it can reinitialize itself to the
previous estimate without spending time recomputing the frequency estimate.
The ntp.drift file contains one line with the following format: freq_offset flag Specifies the nominal frequency offset. DO NOT modify
this field. Specifies the method used to improve system clock accuracy. Specifies that xntpd runs a Phase-Locked Loop (PLL) algorithm to
keep synchronized with other hosts. This is the default. Specifies the use of the PLL algorithm in the kernel. This requires the
NTP_TIME kernel option. After the option is configured in the kernel, edit the ntp.drift file and change the flag value to 1.
See System Administration for information on the NTP_TIME kernel option.
