I’m having a warranty discussion with D-LINK Auatralasia, the supplier of a Network Storage (NAS) device that copies a 5Gb file in 7 hours – not satisfactory!
He’s shown me this picture of a cd.iso file being copied from his windows box, along a crossover cable to his (D-LINK DNS-313) NAS mounted as a Z: mapped drive in his windows box:
He wants me to create the same sort of test and supply the results to him for warranty purposes but I have not got such software.
Here are the questions:
What is this all about this “push” and “pull” stuff. Is it normal/common, accepted, technical jargon.
Is there some kind of similar benchmarking software in Linux where I can measure the speeds of LAN transfers (maybe in “push” and “pull” jargon) so I can talk transfer rates to him in a style similar to the information he sent to me?
Thanks for any help

PS I found “Network Probe” for windows from h_etc://www.objectplanet.com/probe/ But I need something for Linux
Think you’re after iostat if you want disk monitoring, which I guess as I presume it is seen just as a mounted fs. If not then I guess you want network throughput iperf.
Though if the latter not sure how to do that as from my limited reading it seems to need a server and client.
As for push pull that will be up down but not fed down, pulled down, but as NAS I doubt it is feasible to push down, but not sure not something I know a lot about.
This software is for measuring up- and downloadspeed via a wireless network connection (“pull” meaning download it from the remote site to your PC (from D: drive to Z: drive in Windows) and “push” meaning upload it from your PC to the remote (from Z: to D:). With KDE you can simply use KNemo to do the same. Software that specifically can measure network speed is iPerf, but than you must be able to also load iPerf on the other machine (there are both Linux and Windows versions, and also a Java GUI).

First off, remember that supposed 1Gbit NAS units from suppliers
like D-Link are usually just slightly above 100Mbit. Just in case
anyone wonders (it’s usually in the fine print on the box).

Not sure about “push” or “pull”, but you can use something like
iptraf to see what kind of throughput you’re getting. Now… with that
said, iptraf will not work will all network interfaces… but give
it a shot. It’s very useful for seeing what is happening right
now… thus you can see pauses, etc.
Hi
Not related to that link I sent you about Link Layer
Topology Discovery (LLTD) Protocol?
My linksys NAS 200 (mirrored drives and xfs fs) transfers via cifs mount
over wire at around 3.5MB/sec (around 1GB every 5 mins) and over
wireless almost 1.0MB/sec ( around 1GB every 15 mins) with this
netbook, a little faster on the other notebook as it connects at 54Mb
this netboot 48Mb.
The NAS cpu runs at 50bogomips…lol not very fast

Thanks for all your suggestions guys. I’ve tried them but the problem of course didn’t resolve just because I could demonstrate a low transfer rate to the warranty ppl in standard terms.
So instead of focusing on swapping the various network interfaces on my LAN as recommended by the D-link ppl, I got frustrated and formatted the NTFS drive just to see what would happen and bingo – fixed.
