Constant receiving on LAN?

Hi all

Can any one explain why my Porteus Desktop edition (3) is constantly receiving data over the Ethernet.
To confirm I typed the following in a terminal and ran every now and again and sure enough the received bytes kept on incrementing
along with the activity LED flashing.

Code: Select all

ifconfig eth1 | grep RX
Note that eth1 in the Ethernet and eth0 the wifi.

Thanks in advance.
Dave

Are you sure it isn't receiving checks from the router that you're still connected?

That would interest me too.
I also noticed this.
Look here:

Boot standard vanilla porteus
Connect to the internet
Wait 1 minute
issue: netstat -t -u

What is the output?

All the time? surely not.

@brokenman
yup, netstat, I know...
But because I do not see this behavior with my 2nd OS (Slitaz) I'm assuming
this is not necessary to hold the Line.(Router, Probe / response)
therefore the Question is still remaining,what causes the flashing WiFi-LED
indicating Network Traffic.

I don't use Slitaz but I do use Puppy, Tiny Core, XP and 7 and have never seen this behaviour before.

If you are talking about traffic between your computer (running vanilla Porteus) and the wireless then I do not see this but I guess it will depend heavily on your modem brand/model and wireless drivers.

For the link between your modem and ISP, there will always be traffic backwards and forwards as they send ARP requests and check that you ip is in use etc. It could even be the driver code in the kernel as in this link:

@donald/Dave

maybe you could install wireshark and track what type of traffic it is?

Good idea.
I assume the SlackBuild at the url below will be OK?

no as it's 6 years old. please use precompiled package - download it through USM.

Hi fanthom

I don't like using USM as it has never worked properly for me in so far as it does not always collect/report on the required dependencies.

EXAMPLE 1:

Tried VLC, after downloading everything required and converting to XZM, and activating the new module in /temp/usm, I launched vlc and it complains that I need qt4 plug-in compiled, it could have checked it first.

EXAMPLE 2:

Tried wireshark and after everything complained about not finding liblua.so
I did a 'whereis' and sure enough only thing is liblua.a

USM tracks only shared libs and everything ".a" is static.
please download 'lua' package through USM and check if that helps.

USM is adaptable, meaning that if people post these 'missing libraries' I can add them to the database so USM picks them up.
