My 100MB NIC is running at 10MB.
My via-rhine NIC seems to be running at 10mbit/sec instead of 100mbit/sec. I'm copying gigabytes of data from a windows box to my Arch box using pscp.exe (a windows scp clone). With other distros, pscp copies at 11,000 kB/s, but right now the linux (Arch) machine is only receving data at 1,700 kB/s.
Normally it copies at 11 megabytes per second, and it is copying about 1.5 megabytes per second currently.
Is there an easy way to test your NIC's speed? My Linksys router doesnt have a "high speed" light, and my internet connection is only 10MB
At the risk of being joked for buying my DVD's from the CompUSA $9 rack, here are my speeds (these are 1.5 MB per second, right?):

thx!
Which NIC are you using?
It may not be that your card is coming up at 10 Mb/s it may be that it is coming up half-duplex. My 3com 905 started to do this for some reason and it will drastically slow down connections. In fact the faster the connection should be, like a LAN, it will be slower.
I just forced full-duplex and all is back to normal. For 3c59x you add this to your /etc/modprobe.conf, of course leave the alias eth0 3c59x line alone.
options 3c59x full_duplex=1
If you don't have a 3com you can probably do a modinfo and look at the params it accepts.
modinfo <module name>
Hopefully that helps you out.

Determine if NIC can run on Gigabit network
I have a bunch of Solaris servers that will be moved to a gigabit network connection. How do I view the network settings on the network cards and determine if they can run on gigabit network? What commands I can use? This will help me if my group has to purchase new network cards. Thanks for you help.
You can also trawl the Sunsolve support web site for Infodocs,
and spend time at Docs.Sun.Com and the Sun System Handbook, as well.
Generally, you just need to "know" your hardware.
Your newer systems will likely have a gigabit interface inside,
while the older systems will only have 10/100 chipsets for connectivity.
Your bge interfaces tell me those are newer systems,
with a Broadcom Gigabit Ethernet chipset.
hme is a 10/100 chipset that was widely use in a previous generation
of Sun's SPARC-based systems. ( Highspeed Media Ethernet ) -
H55M-E23 NIC negotiation issues
Hello,
i have purchased a desktop PC with H55M-E23 with Realtek Gigabit 8111E/8186, 4GB RAM, Ge-Force GTX 460 1 GB, Intel i5 processor running on Windows 7
i have an issue with this particular NIC, it resets to 10Mb, what ever i do.
i tried changing drivers to included with MotherBoard, tried different drivers, including newest from Realtek website, , it automatically resets to 10Mb and all speed tests and window task manager shows that,
i tried manually setting speed to 100Mb full/half duplex, to 1Gb no effect, it automatically resets to 10Mb and all speed tests and window task manager shows that,
i tried turning of Wake-On-LAN, and any of possibly related options in advanced section of the device (power consumption, magic packets, and so on...), it automatically resets to 10Mb and all speed tests and window task manager shows that,
i tried turning off the power to the PC and removing the bios battery, it automatically resets to 10Mb and all speed tests and window task manager shows that,
i switched wake up events from bios to OS, it automatically resets to 10Mb and all speed tests and window task manager shows that,
i checked router/switch if the speed is set to 10Mb, forced it to 100Mb, it automatically resets to 10Mb and all speed tests and window task manager shows that,
only thing that "occasionally" helps is reinstalling drivers, that helps for some time, not often to switch to 100Mb (i have router with capabilities only of 100Mb).
please help me, because currently only option i see is to buy a new NIC, thank youCan you test with another Cat 5E or Cat 6 RJ45 cable?

How to Get In & Out of Match, Get your Downloads and Run
How to Get In & Out of Match, Get your Downloads and Run
So you have read the marketing hype, and are thinking what you really want is to pay for the service to upgrade your low quality bitrate files to a bit better 256KBPS rate easily, as don’t fancy rebuying/ reimporting or other method
This guide should show you the fastest route to achieve you upgrades
It assumes you’re working from your main music library, and know something about IT, and have <25k of music files
Backup your music files
If you know how to do this, its simple right – so once done then move to step 2, if not read below so you don’t blame me for a loss
Transfer Hardware
your choice the transfer hardware, suggest offline harddrive via USB3.0 (blue USB connector/eSata/ 1494b/1GB NIC/etcetera but your call
If you use USB2.0/ 100MB NIC/1394a or other lower transfer method, accept the time hit
Don’t use Time Backup/local disk backup software unless you have RAID 5 setup or better (and if wondering what that is, you almost certainly don’t then)
Don’t use internet backup service unless you live next door to the hosting company, with stunning internet connection to envy 99.9% of the human race, remember this is the fast method folks)
Transfer Software
I am assuming you know how to do a copy n paste/ robocoby/xcopy/drag n drop or whatever method turns you on via finder/explorer/cmd window ect
Caveat #01: If not sure how to do above, then stop now as you are not IT literate ready for this
Find your music files and back them up
Now keep the computer running, preferably with nothing else running from this point for ease of use bar an active internet connection, and power saving switched off
If you know where the files are great, backup the files, but some don’t so for them as below
Caveat #02: if you don’t know how to find them your most likely on default settings, or sitting with a legacy from a past upgraded machine - below should help but you might want to stop now if you have never been curious about the location before
Within iTunes , go to [Edit/Preferences/Advanced] and note down the location shown for Itunes Media Location
In the same location of preferences, hit [Keep iTunes Media Folder organised] and let the application do its stuff. You will end up with the location in 1ciii a ready to copy location which for simplicity of topic, copy the whole folder and its subfolders. You may end up with some extra copies of music files (an iTunes safety mechanism, but it won’t show in the folder location, and we can ignore later on)
Enable Match (after paying for the service)
Run Match
Accept that the Apple iTunes process is not perfect, may crash/stop/pause and reboots will be needed, and we can move on so to speak. Key here is you cannot do an unattended script or assume no end user interaction needed L
Turn on iTunes Match, notice the new ITunes Match on the left hand sidebar, click it, then hit the Start button – if it works and you eventually get to STEP 3 perfect.
If it fails before getting to STEP 3, reboot and restart
If this still fails to get to STEP 3, then create a new iTunes database (browse forums on how to do), read your media files from the location in 1civ
Stop MATCH (the upload process only, not the service)
Once STEP 3 starts, CLICK STOP - ASAP, as all this does it upload data, and you don’t want to do this, just get your upgraded files (remember the title of this entry your reading!)
This also avoids future issues with Album art lost
Delete Matched low bitrate files
Create a NEW SMART playlist, with two criteria
Show all files with bitrate is less then 256
Show all files where iCloud status is MATCHED
In the new playlist, click it and it shows the files we want to blow away.
Click Edit / Select All then
Click ctrl in windows/apple (cmd) logo in mac, and press delete button, ensuring you do NOT tick the delete from iCloud Option. Now want a few mins for it do do its stuff.
Download Upgraded BitRate Files
In the same location as 5, reselect all, and right click, and select the option to download all, and off it goes
On the lefthand sidebar in iTunes, click Downloads, and you will then see in the middle bottom screen an option for simultaneous downloads (select it)
Your done Just let the app now do its stuff. I would ignore the message saying you can get on with other things, and use anther machine, preferably not using the same internet connection.
Optional Steps:
Click randomly from the Itunes/Matched/256KBPS listed files, and play them. Not all the files, one every 30 or so, and just the start, then last few seconds to check not dead or corrupt files.
Update your Step 1 backup with the new files, which is going to take up more space, guess at 40%.
Kill your iTunes Match account (both the recurring automatic subscription, and the account if not continuing to use the store part of iTunes)bump

Why won't my vi run outside of the LV2011 project explorer?
I've created a LV2011 project. The vi's within this project open executables to perform measurement functions. When I open the vi's from within the project explorer window the executables open with no issues. However, with the LV project closed and opening the vi's from "windows explorer" the executables won't launch. It seems like I need to have the LV project explorer window open. However that does not work very well in a manufacturing environment. What is the dependency relationship of running vi's in or out of the LV project? How can I remove this dependence?
crossrulz,
Good point. Nice to run executables and I agree. In a perfecct world thats what would happen. Do you know what the constraints are for vis in a LV project? Here is the error:
Error 1172 occurred at Error calling method Class.Initialize, (System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
Inner Exception: System.Runtime.InteropServices.COM Exception: An error has occurred in the vi. More information may be available in the Windows Event log.
Creating vi)
Possible reason(s):
LabVIEW: A .NET exception occurred in an external assembly. For information about correcting this error, copy the following exception (in bold), and search the Microsoft Developer Network (MSDN) Web site or the Web for a possible explanation.
System.Runtime.InteropServices.COM Exception in Open apps.vi->Example.vi

Losing network connection and NIC acts weird from warm/hot weather/temperatures?
Hello.
Is there a known issue on MSI P43 NEO3-F (MSI-7514) motherboards' onboard RealTek RTL8168C (P)/8111C(P) PCI-E Gigabit Ethernet NIC network disconnecting and acting weird during warm/hot weather?
I noticed lately and back on 1/11/2009 night when weather got warm/hot (e.g., my room can get over 85F degrees, but lately it has been 80F degrees), my network would lose its connection. See http://img9.imageshack.us/img9/5580/screenshots.gif for a few SpeedFan's sensor readings when the incidents occurred. I have never seen this happen when the weather is cooler (60-70F degrees in my room).
I also think this only happens if I am using the PC lightly (nothing intensive) like watching fullscreen videos (video overlay), surfing the Web, etc. I don't see any errors or evidences that it happens when idled (e.g., asleep or out). Uptime doesn't seem to matter since I have seen days to 3.5 hours.
I tried upgrading network driver twice (e.g., Realtek_XP_5714_0219 from
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false ...), disabling Kerio Personal Firewall v2.1.5 (XP's disabled already), releasing and renewing IP address (works, but still no network -- can't even ping my router!), unplugging and replugging the cat5 cable (do see the network port lights on), touching the network jack and hardware inside and outside of the case (not hot), trying another cat5 cable and a network port on a switch instead router's), changing from "Minimal Power Management" to full power (no underclocking/slowing down when idled), etc.
During the disconnections, I tried:

I also noticed the disconnections usually start with red X icon in my taskbar with its bubble and then later the long disconnection even though no red X (1 GB and connected). If I were to disconnect the cat5 cable from NIC, then it wouldn't even detect it is missing the cable!
The only way to fix this was to reboot (best way and last longer) OR disable network connection and re-enable it (Windows XP's Network Connections) or the NIC itself (Device Manager), but that doesn't always last long (maybe a minute). Example of my pings right after disabling and re-enabling NIC:

Force your NIC to run at 100Mbps full duplex and see how it goes.
Check your router / switch ports as well as cables.
I will try 100 Mbps if it happens again. So far, it hasn't occurred after installing the driver supplied by MSI's Web site and not RealTek's Web site. The room temperatures even got warmer like 83F degrees.
As for router and switch, what am I checking for? Other computers didn't have any problems. As for cat5 cables, I already tried another one like I said in my original post. -
As Dell and Sun provide PCI-x or PCI-e only, with just 2 build-in NICs, while server admins are quite reluctant to add additional NIC to run in traditional way, like Front-end NIC, Backup NIC, Load-Balancing-NIC, Mgmt NIC cause the PCI-x or PCI-e are quite expensive, not sure you encounter such issue or not, and how would you like deal with such issue and cater server's requirement, because we are quite reluctant to offer 802.1q trunk to server NIC either in our data center where we have hundreds of servers which are sitting behind FWSM(s). thanks.
Best Regards.
LeoFrom a networking perspective, there is not too much difference between trunking and adding additional adapters in hardware.
With more adapters in a server it also becomes more complex to control routing.
A more preferrable method (at least in my opinion) is to assign the servers into relatively small VLANs. These VLANs can be set up for servers belonging to the same customer or (load)sharing the same application.
With smaller vlans you are able to use a single or teamed adapter for all traffic flows and you are still unlikely to run into network-load issues.

Run compiled application (LV 8.6) without run-time engine
Hi,
I just recently wrote a small 200KB program that performs simple calculations that I'd like to use on several different computers. The application works perfectly, but the problem is that I really don't want to go through the download/install/reboot process of installing the LabVIEW Run-time 8.6 software on every single computer (especially since downloading a 100MB file to run a 200KB program seems counter-intuitive). Is there a way to get the application to run without the engine? Previous searches resulted in old posts of people simply copying the engine files from the shared folder into the application directory, but that did not work when I tried it. Is this no longer possible on LV 8.6? I'll have no choice but to rewrite the application in a different programming language if LabVIEW isn't capable of running standalone compiled applications.
Thanks,
AnthonyI made the test with LV 8.6 on Windows.
I used a VI which does not need any drivers neither serial nor any other hardware execpt the graphics card.
I made an application from this VI on my normal development machine and checked that it will start and work as expected.
I setup a NI free partition with Win XP Prof. SP2. I have some non NI programs installed like a virus scanner, defragmentation tool, Adobe Reader, a drive imageing tool and WLAN drivers. The .NET Framework 2.0 is installed.
I copied the application and all files under National Instruments\shared\LabVIEW Run-Time\8.6 to the machine in a temporary folder.
I booted the machine into this partition. The application will start and work as expected. You do not need to make a complete runtime installation until you do not need any drivers.
The above mentioned folder has a size of about 64 MByte. Dependent on the application and desired languages you can remove parts of it.
Dennis,
during the various LV 8.x versions it was possible to do it as described above exepct one version, 8.2 I think, which needed an ini-File in the Windows folder.

R9280x all of a sudden running slower
Hey there , so I got my 280x today in my post was SUPER excited .. for half the day the card was runnin really nice , was running at all the speeds adverstised , in the oc mode it was running at 1k + in gaming mode 900+ then all of a sudden now it wont go above 850 ? Is there any way I can fix this? is it a software/bios issue? or is my card borked and needs to be sent back.
any help will be really appricated . thanks a lot.bumping because I dont know what to do

Is it possible to run with a 30GB iPod Video? Or will it ruin the internal disk? Would I be better off getting a shuffle or something to run with?
I used to run with my original 1st gen 5 gig iPod. I didn't run very much and kept it in a neoprene case clipped to the inside of my shorts so it didn't seem to bounce much. Lo, these many years later, it still works. I have heard that the original iPods were a bit sturdier than their later, higher capacity descendants. That being said, I agree with deggie. The Nano is much nicer to run with. I have a 3rd gen and a Nike+ Sport kit (you don't need Nike shoes to use it, by the way). I hardly feel it. Nano would be the way to go especially if you can get a good deal on one.
Best of luck. -
Hyper-V 2012 VMs freeze on large file transfers
I have a small non-clustered Hyper-V Server setup as follows:
HP ML350p Gen8 Server, 6 core E5-2620 CPU and 32GB Memory running Server 2012 (full GUI) with the Hyper-V role enabled.
The Server has 8 disks, 1 pair of RAID1 15k disks for the Server 2012/Hyper-V OS, and 3 pairs of RAID1 10K disks for 3 VMs (ie each VM has its own pair of RAID 1 disks). The NICs in the Server are 4 x gigabit ports on an internal
331i card and 4 x gigabit on an external 331T card. The Hyper-V Server is not running anything other than the Hyper-V role, the LogMeIn client and Symantec SEP SBE 2013 (with recommended Hyper-V exclusions in place) and
the VMs are a Domain Controller, a SQL Server and a File Server. Currently all VMs have their own single 1GB NIC connection on the 331T card, all VMs have a single IP address and are on the same subnet, no VLANs are used.
I have applied what hot fixes I can from a TechNet article that recommended how to setup Hyper-V.
Initially I had a problem with NIC latency during pings, which we traced to being due to the ML350 Gen8 Server's NICs not liking VMQ enabled. When disabled all looked fine, but we had not yet tried to use the Server in production.
Recently (getting ready to go in to Production use) we have noticed when transferring a 3.5GB ISO of SQL media to a file share on one of the VMs from a desktop PC that this causes the VM to lock up. The file copy will still complete but the screen freezes
when accessed via Hyper-V manager or remotely via LogMeIn and sometimes the LogMeIn remote session is dropped too. If you cancel the file copy the console is immediately responsive again.
Since we built the server a while back, HP had subsequently released an updated NIC driver which we installed and it seems to have fixed the VMQ issue, but with or without VMQ enabled we seem to experience the lockups as soon as we transfer medium to large
size files. The issues were there before and after we upgraded the NIC driver, we were hoping it would address the issue, but it didn't. These servers are very lightly loaded and the problem occurs even on the SQL Server VM with the SQL service disabled
(ie the server has hardly anything running at all and the console freezes with a single user performing a single file copy).
We have 3 VMs on the Server, 2 are running Server 2012 and seem to be more affected, the VM running Server 2008 R2 seems less affected. VM to VM transfers seem to be working better (ie slows down slightly but no lock ups), it is only during external network
transfers. Also the faster the transfer speed is, the worse the issue becomes. If the file is copied to a share on the Hyper-V Host the issue does not occur, only transfers to the VMs.
Does anyone have any idea what might be the issue here? I saw a hotfix for 2008 for a similar issue but can't seem to find anything for Server 2012.I think we have tried almost every combination of disabling Large Send Offload, TCP offload, IP SEC Offloading, VMQ and Receive Side Scaling possible - in the various places there are - although I will be quite honest - as there are 3 places to do this
for each Server (the related physical and virtual NICs on the HV Server, and also the NIC in the VM) it is possible we may have missed an iteration...
During our testing we have noticed that the symptoms of the problem gets worse the higher the transfer speed is. For example if you transfer to the VM from a desktop with a 100Mbs NIC, there will be subtle lag and a transfer speed of say 10 or so KBs ,
if you use a device with a 1Gbs NIC, you on average achieve 50-70 KBs transfer speeds and the higher the number, the worse the GUI / Server locks up (although the transfer completes just fine).
We also tried throttling the bandwidth via the 2012 GUI - to see if that helped, but none of the changes we made seemed to work, and we did not have time to try the powershell way of doing this.
We did replace one of the VM's NIC with a legacy one as part of our testing today, and now data transfers to the VM from a PC with a 1Gbs NIC run slower at around 30-35 KBs and the are no noticeable GUI freezes, although during the large transfer
it looks like 1 in every 30-40 packets is dropped in a continual ping that runs during the transfer period.
We have done a lot of cable replacing today (out of diligence) but there seems to be no noticeable issue. We also tried and older NC380T dual port NIC we had available and used the standard driver Windows offered instead of an HP one, but the problem
was identical no matter which NIC we used. -
Win2k Server can't see the drives on Compaq VA7400 Disk Array
I have attached a Win2K server with (10/100MB) NIC to Cat 29478G, then connect the Gigabit Ethernet port to the SN5428. The VA7400 is connected to fc2 on SN5428. I can see all the drives on VA7400 in the SN5428 web admin page. The iscsi driver (v2.2.1) is installed and the status is ok.
However, I couldn't scan the disk from win2k disk manager unless I install the Veritas Volume Manager 3.0
Is it VxVM is a must for Cisco;s iSCSI solution?Thanks mrfrase.
I am now facing another problem. I have attached all my devices together
I can see my iscsi status is active to the scsi routing instance.
I can see my array is presented in the SN5428 by "sh devices"
i can see my iscsi routing is active in the router
I can ping my server with iscsi driver installed
but the Cisco Psuedo SCSI drive is still not running!!!

What is the problem? -
Hello:
I'm having problems playing f4v video is very slow. The size is 100 MB and resolution 1280x720. When I play out of Flash it reproduces well.
I need to play in Desktop application not over Internet.
What I'm doing bad? Is there anywhere to play well or wich is the better option to do it?
thank you very much.
This is my code:
import flash.net.NetConnection;
import flash.net.NetStream;
import flash.media.Video;
import flash.events.AsyncErrorEvent;
//fullscreen
stage.displayState = StageDisplayState.FULL_SCREEN;
var conexion:NetConnection= new NetConnection();
conexion.connect(null);
var display:NetStream = new NetStream(conexion);
display.play("videos/ocioelecer.f4v");
var video:Video = new Video(1280,720);
video.attachNetStream(display);
addChild(video);
display.addEventListener(AsyncErrorEvent.ASYNC_ERROR, noshow);
function noshow(event:AsyncErrorEvent):void{
//no show error
display.addEventListener(NetStatusEvent.NET_STATUS, statusHandler);
function statusHandler(event:NetStatusEvent):void
switch (event.info.code)
case "NetStream.Play.Start":
trace("Start [" + display.time.toFixed(3) + " seconds]");
break;
case "NetStream.Play.Stop":
//End video
trace("Stop [" + display.time.toFixed(3) + " seconds]");
(root.loaderInfo.loader.root as Object).removeSWF();
break;100MB played locally is nothing. Most HDs have burst cache which can load up to 200MB instantly off disk. You shouldn't even need to (but might want to on a really 'value/green' rated drive) set the buffer to require 1 second of data before playing (bufferTime = 1).
Are you using any kind of integrated graphics, like using a Z-esque Intel chipset with Intel 2000/3000/4000 graphics? Sometimes people over-estimate how well their built in hardware decoders perform.
You always want to add Event listeners before you invoke a method that uses events. In your code you're adding listeners AFTER invoking a 'play(...)' method. Just for best practice, run the load(...) last.
Lastly is the video available for inspection? 100MB for 10 seconds is 10MB/s, which is really only required in excessively high quality rendering with a huge gaumet with high motion. 9mbit is average full quality 720p (which is 1.25MB/s). You may have your bitrate set too high as moccamaximum mentioned if you are not in that video situation or striving for lossless video in ultra high motion. -
TimeCapsule (and AirPort extreme too) hangs on large file transfers
Greetings,
I got a following problem. I had install AirPort connected to my router with copper and extend network with TimeCapsule. TimeCapsule have two USB drives attached, AirPort - one USB. When I am transferring a large file, in a magnitude 2-3Gb or multiple simultaneous transfers of smaller files to/from those USB drives, depending on which drive I am using the AirPort or TimeCapsule get crashed. For plain user it is looks like as of sudden, data transfer stops, led in a front keeps green, and I can not reconnect to the drives. If I powercycle TC or AES everything get back to normal. Are there anyone else experiencing the same issues and if yes, what would be solution ?
