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

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 can't tell what the output of the netstat command means. Is there anywhere that has this information? I tried the man pages, but they weren't helpful. (3 Replies)
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..

nos-tun
NOS-TUN(8) BSD System Manager's Manual NOS-TUN(8)NAME
nos-tun -- implement ``nos'' or ``ka9q'' style IP over IP tunnel
SYNOPSIS
nos-tun -t tunnel -s source -d destination -p protocol_number [source] target
DESCRIPTION
The nos-tun utility is used to establish an nos style tunnel, (also known as ka9q or IP-IP tunnel) using a tun(4) kernel interface.
Tunnel is the name of the tunnel device /dev/tun0 for example.
Source and destination are the addresses used on the tunnel device. If you configure the tunnel against a cisco router, use a netmask of
``255.255.255.252'' on the cisco. This is because the tunnel is a point-to-point interface in the FreeBSD end, a concept cisco does not
really implement.
Protocol number sets tunnel mode. Original KA9Q NOS uses 94 but many people use 4 on the worldwide backbone of ampr.org.
Target is the address of the remote tunnel device, this must match the source address set on the remote end.
EXAMPLES
This end, a FreeBSD box on address 192.168.59.34:
nos-tun -t /dev/tun0 -s 192.168.61.1 -d 192.168.61.2 192.168.56.45
Remote cisco on address 192.168.56.45:
interface tunnel 0
ip address 192.168.61.2 255.255.255.252
tunnel mode nos
tunnel destination 192.168.59.34
tunnel source 192.168.56.45

Nickolay N. Dudorov <nnd@itfs.nsk.su> wrote the program, Poul-Henning Kamp <phk@FreeBSD.org> wrote the man-page. Isao SEKI
<iseki@gongon.com> added a new flag, IP protocol number.
