I put below command-
could you please describe the outputs column-
let me describe some them-

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.

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..

pvm_recv
RECV(3PVM) PVM Version 3.4 RECV(3PVM)NAME
pvm_recv - Receive a message.
SYNOPSIS
C int bufid = pvm_recv( int tid, int msgtag )
Fortran call pvmfrecv( tid, msgtag, bufid )
PARAMETERS
tid Integer task identifier of sending process supplied by the user.
msgtag Integer message tag supplied by the user. msgtag should be >= 0.
bufid Integer returns the value of the new active receive buffer identifier. Values less than zero indicate an error.
DESCRIPTION
The routine pvm_recv blocks the process until a message with label msgtag has arrived from tid. pvm_recv then places the message in a new
active receive buffer, which also clears the current receive buffer.
A -1 in msgtag or tid matches anything. This allows the user the following options. If tid = -1 and msgtag is defined by the user, then
pvm_recv will accept a message from any process which has a matching msgtag. If msgtag = -1 and tid is defined by the user, then pvm_recv
will accept any message that is sent from process tid. If tid = -1 and msgtag = -1, then pvm_recv will accept any message from any
process.
The PVM model guarantees the following about message order. If task 1 sends message A to task 2, then task 1 sends message B to task 2,
message A will arrive at task 2 before message B. Moreover, if both messages arrive before task 2 does a receive, then a wildcard receive
will always return message A.
If pvm_recv is successful, bufid will be the value of the new active receive buffer identifier. If some error occurs then bufid will be <
0.
pvm_recv is blocking which means the routine waits until a message matching the user specified tid and msgtag values arrives at the local
pvmd. If the message has already arrived then pvm_recv returns immediately with the message.
Once pvm_recv returns, the data in the message can be unpacked into the user's memory using the unpack routines.
EXAMPLES
C:
tid = pvm_parent();
msgtag = 4 ;
bufid = pvm_recv( tid, msgtag );
info = pvm_upkint( tid_array, 10, 1 );
info = pvm_upkint( problem_size, 1, 1 );
info = pvm_upkfloat( input_array, 100, 1 );
Fortran:
CALL PVMFRECV( -1, 4, BUFID )
CALL PVMFUNPACK( INTEGER4, TIDS, 25, 1, INFO )
CALL PVMFUNPACK( REAL8, MATRIX, 100, 100, INFO )
ERRORS
These error conditions can be returned by pvm_recv
PvmBadParam
giving an invalid tid value, or msgtag < -1.
PvmSysErr
pvmd not responding.
