Description kenth 1999-02-25 06:59:14 UTC

try

netstat -ic

while doing a transfer or moving lots of data.  The first
reported values don't seem to ever change.

This is with
net-tools-1.50-0

downloaded from updates.redhat.com/.../kernel2.2 (or
something like that)

on a Linux 2.2.1 kernel.

Comment 1 David Lawrence 1999-02-25 20:59:59 UTC

I was able to replicate this problem in our lab. When using the -c
switch to netstat it fails to update the numbers being displayed. If I
control-c and then rerun you can see that there was in fact changes.
This has been passed on to a developer.

Comment 2 Jeff Johnson 1999-03-25 01:32:59 UTC

Fixed in net-tools-1.51-3.

Comment 3 Jan Iven 2003-07-24 09:07:32 UTC

Please re-Open, apparently this is still|again broken, tried
 net-tools-1.60-4 (RH7.3) and net-tools-1.60-12 (RH9). Both times 

netstat -ic 

will simply repeat the header line, as below (this is over ssh, so the output
alone should be enough to create some traffic)

# netstat -ic

Btw, the man page claims that 
netstat --interface=eth0 
should only show eth0, but actually you get an error (ditto --interfaces="eth0",
"-i eth0" simply ignores the "eth0" bit):

netstat: option `--interfaces' doesn't allow an argument
usage: netstat [-veenNcCF] [<Af>] -r         netstat {-V|--version|-h|--help}
