Dear All,
I have Dell PowerEdge T 1800 server. I have installed ubuntu 11.10 x64 desktop version. The PC has 1 Gbit ethernet card but under Ubuntu the ethernet card is working only 100 Mbit.
Two host machine's one as a client and other as a server, i am testing udp load-test in these two machines.Machine Ethernet speed is 100 Mbps but i want to send 30000 packets each of 512 bytes at 1 Mbps speed how to do? Is their any Linux command to set Ethernet speed at 1 Mbps?
OK, anyone seen this?

this guy wraps the ends of an Ethernet cable with another Ethernet cable and he claims it doubles your internet speed. I tried it, didn't work for me. BUT I did find that specific cables I had did work better then others, it didn't matter if they had the special wrapping or not.
I am experiencing a very annoying and mysterious behavior when sending magic packets (for Wake On LAN) shortly after pinging an Intel 82579LM GigaBit Ethernet Controller (the onboard ethernet controller of the Intel DQ67SW motherboard).
So basically if I send an icmp echo request and wait a time dt before sending a magic packet I will experience the following:
dt < 1 second:

Hi all,
I have a vcd file with a bunch of lines containing an array, like this
Code:
$var wire 1 b a[0] $end
$var wire 1 c a[1] $end
$var wire 1 d a[2] $end
$var wire 1 e a[3] $end
$var wire 1 f b[0] $end
$var wire 1 g b[1] $end
$var wire 1 h b[2] $end
$var wire 1 i b[3] $end
I want it like this:
Code:
$var wire 1 e a[3] $end
$var wire 1 d a[2] $end
$var wire 1 c a[1] $end
$var wire 1
I have a project where I'm wiring my home for ethernet. I have four bedrooms upstairs, all of which are getting two ethernet connections each, and then a few rooms downstairs as well. I was thinking of a few options, tell me what's best.
Brocade this week rolled out 10 Gigabit Ethernet and 8Gbps FibreChannel modules for its routers and storage-area network switches designed to increase the wire-speed density of both platforms to better support network consolidation and improve service levels.
Ok, this sound might stupid - but is there any negative on just enabling jumbo frames in practice?
From what I understand:
Any switch or ethernet adapter that sees a jumbo frame it can not handle will just drop it.
TCP is not a problem as max frame size is negotiated in the setinuo phase.
UCP is a theoretical problem as a server may just send a LARGE UDP packet that gets dropped on the way.

I'm trying to wire up an old college office (with 3 rooms) that has thick cement walls.
