Set speed limit to network interface

Hi
I want build a program to set limit speed to my network interface
for example max download speed for wlan connection 10Kb
how must edit network interface for this work
i searched but can't found anything
thanks

Why would you want to do this?
It sounds quite suspicious to me.
Still lost in code, just at a little higher level.
i want save my monthly traffic
That doesn't make much sense. How will limiting the network speed do that?
If you limit the network speed to 20% of what it was then it will just take 5 times longer (more really due to the amount of overhead in data packets) in order to upload or download anything.
If you are on a plan which limits the amount of data via the plans network which can be uploaded and or downloaded during the plans payment time period then perhaps you should monitor the data transceived over the link during that time period.
Then write an app that turns off a NIC and will monitor the NIC so if it is enabled it is turned off again whenever some daily allowance of bandwidth is exceeded. Or perhaps write a service for that. Of course the app or service would need to know the pay
period to monitor, the amount of bandwidth provided for the pay period, constantly store bandwidth used (either sent, received or both) while the NIC is up and be designed to know for each day when to disable the NIC if necessary. And allow the NIC to be re-enabled
or re-enable the NIC when some time occurs following the previous disable of a NIC.
However you don't provide what the requirement would be other than you just want to limit bandwidth via some NIC. Which really means nothing unless multiple PC's are vying for bandwidth and you want on specific PC to be allocated more bandwidth than
any other PC or something.
Group Policy Editor has a setting that can apparently
limit reserveable bandwidth. I don't know if setting that to %95 would only provide applications %5 of the available bandwidth. I've installed GPE on my Win 7 Home Premium PC which it does not come
with and I had to find an installer from an untrusted source in order to do that.
Recently I had a friend using a Verizon WIFI device which provides local WIFI for PC's via Verizons cell service I suppose. Apparently if the PC was left on and nobody was using it then bandwidth was used. I believe in about one 6 hour time period over %15
of the entire pay periods bandwidth allowance was used when his girlfriend let the PC on unattended. So I could see where some type of monitor app would be nice for a situation like that.
When you use few words to describe anything the result is everybody having to guess. And with regard to what you think you want to do it makes the entire thread a guess.

Setting Up a Second Network Interface.

Hi All,
I am really quite new to Solaris and UltraSpac 10's, so please keep that in mind when responding. (newbie):D
I have a Sun Ultra 10 which appears to have to ethernet ports. One of which I believe looks to be intergrated to the motherboard and the other whcih looks to be attached to a PCI slot.

I can't see a hme1 or anything, is what I am seeing at the back of this Ultra10 box an ethernet port of a NIC?
How can get the (either/or both) NIC to work?
Thanks in advance for any replies.
If you need anymore info, please let me know and I will gladly provide it.

UPDATE:
Sorry,
I don't know what I have done,
but it appears I have a "hme1" in the "Connection Properties" and in ifconfig -a?
Still appears to be disconnected though.

Hi, Everyone.
Just had a resolution to my problem.
It seems the Network at my workplace has some funny switches.
I used an extra switch between work switch and solaris box and it seems to be all working well.
Thanks for all your help

Trying to set network interface at 100/full on Solaris 11

Hi all,
I hope someone can help me.
I've built two boxes running Solaris 11 in my lab. Connected to a hub, all seemed well.
Now, I've connected them to the network here and I'm having the following issue, The machines should be connecting to the network at 100Mbps/full. Instead, it seems they are trying to connect at 10Mbps/full, which is causing a problem.
When I check the speed on the NIC (interface=net2), speed is set to 10Mb :
     dladm show-linkprop net2
Returns speed=10.
PROPERTY     PERM     VALUE
speed               r-          10
As you can see from the above, permission is set to read only.
When I try to set the link speed as follow :
     dladm set-linkprop -p speed=100 net2
I get the following error
     'Cannot set link property speed on net2 - operation not supported.'
Which I assume is because of the read-only property/
I have also tried setting the property old-style with ndd :
     /usr/sbin/ndd -set /dev/<device-name> adv_100fdx_cap 1
And get 'Operation not supported'.
And finally, I've entered the settings in /etc/system itself (and rebooted) :
    set net2:adv_100fdx_cap=1
All to no avail.
Note the following blog post I've found here indicating someone else had issues with mode/speed in Solaris 11 (unfortunately I'm still stumped!) :
http://blog.thilelli.net/post/2011/02/19/Solaris-11-Express%3A-Problem-6
My networks man is adamant that the network settings are correct, i.e. the network is set to 100Mbps, and looking at his switch settings he seems to be correct.
Does anyone have any ideas as to where I can go from here? Much appreciated....

Despite what your site's network staff have said, this is likely to be their issue.
If you are connecting to a managed switch, that entire peripheral may have specific settings on some or all of its ports.
I suggest you let that switch do whatever it expects to do and remove all customizations to your NIC's configuration.   Let it auto-negotiate.
You should also ignore that link you have in your initial post.   The ERI network interface that is described there was a very specific network chipset and used on a very small specific number of Sun SPARC boxes. It was known to have issues with proper negotiation (it would usually work but sometimes just get mucked up).

How do you to set an limit speed on your router port

Hi, I got a WRT300N and there 4 port. I like to know if we can set an limit speed on 1 of these 4 port? Example, my port 2 is using for download and I like to limit the speed like 50k/sec. If yes, please could you guide me how do I make the settings? Thank you

NO, there is no such settings on your Router, which will control your computer speed, Router will distribute the same speed on all the computers. May be you can search for some software we does that.

Setting network interface IP address

Hello everyone,
Is it possible to change a network interface IP address(eg set my local area connection IP) purely in Java or should JNI be used?
Thanks in advance.

I doubt there is a single, cross-platform way in purely Java, but short of using JNI you could probably use something like Runtime.exec() (assuming your user has proper permissions) and a corresponding command-line utility (like ifconfig on Unix/Linux, ipconfig on Windows).
Edit From a brief look, it looks like ipconfig won't do the equivalent on Windows as ifconfig will do.
Edited by: endasil on 16-Sep-2009 3:37 PM
Edit Looks like the netsh command on Windows does some of those things:
netsh interface ip set address local static 123.123.123.123 255.255.255.0 Source: [Wikipedia: netsh|http://en.wikipedia.org/wiki/Netsh]

Setting applications to use specific network interfaces

How do I configure my computer such that specific applications will default to a different network interface than all the rest?
I want to set it up so that Adium always tries to use AirPort first and everything else uses ethernet if it's available.
Powerbook G4 1.5 Ghz Mac OS X (10.4.8) 1GB RAM

You can't (normally) get there from here.
What you're trying to do is affect the routing (route certain traffic through a specific interface). The issue is that routing works at the IP level, not the application level. This means that you can tell the system to route a.b.c.d (e.g. the address of the IM server you're connecting to) through a speciic router at w.x.y.z (e.g. the AirPort).
In order to do this, though, you need to have different IP address/subnet masks on each interface.
For example, assuming your wired ethernet is using 192.168.1.2/255.255.255.0 and your wired ethernet router is at 192.168.1.1, and your AirPort interface is using 10.1.1.2 with the AirPort router at 10.1.1.1 you can run the command:
<pre class=command>sudo route add a.b.c.d 10.1.1.1</pre>
and all traffic for a.b.c.d will go over the AirPort link.
Note that it doesn't matter what protocol you use - any traffic destined for a.b.c.d, whether it's AIM, HTTP, FTP or anything else - or what application you use - Adium, Safari, FireFox, etc. - they'll all use the AirPort link.
Note that this technique will NOT work if you have both interfaces on the machine configured in the same subnet, but this is not a supported configuration, so you shouldn't be doing that anyway.

Setting network interface and ttl for MulticastSocket

Hello
I've tried to set the network interface and the TTL for a MulticastSocket, but it has no effect. For testing I set the TTL to '4' and the network interface to 'lo' (localhost), but everybody in the local area network get my message with TTL=1...
I use Fedora Core 5 (Linux), with no settings in the iptables.
Here is the code I used:
private String networkInterface="lo";
private String address="239.192.0.5";
private int port=54321;
private int mcastTtl=4;
public void send(){
InputStream input=getContextClassLoader().getResourceAsStream("something.xml");
byte[] buffer = new byte[1480];
int length = input.read(buffer,0, 1480);
inetAddress = InetAddress.getByName(address);
nInterface=NetworkInterface.getByName(networkInterface);
MulticastSocket socket = new MulticastSocket(port);
socket.joinGroup(inetAddress);
DatagramPacket packet = new DatagramPacket(buffer, length,
inetAddress, port);
socket.setTimeToLive(mcastTtl);
socket.setNetworkInterface(nInterface);
socket.send(packet);
socket.leaveGroup(inetAddress);
For simplicity I took the Error handling off here, but certainly I have it in my code. No errors, no problems, everybody get the correct message... But not with the settings I made.
Any tips?
Thanks:
Bence

I'm seeing the exact same thing. It's as if setNetworkInterface() doesn't actually do anything at all.
java version "1.5.0_09"

Java HotSpot(TM) Server VM (build 1.5.0_09-b03, mixed mode)

Code example (parts removed for clarity) follows. This code works perfectly when I allow it to attach to the default (eth0) interface. When I try to change the interface it binds to, all packets are still multicast to eth0 ONLY! I see nothing on lo or eth1.
Properties props = System.getDefaultProperties();
props.setProperty("java.net.preferIPv4Stack","true");

mcs.setNetworkInterface(NetworkInterface.getByName("eth1"));

String payload = "This is my payload";
DatagramPacket dgram = new DatagramPacket(payload.getBytes(),
payload.length(),
group, groupPort);
mcs.send(dgram);

Speed limit

Hi!
My turn to ask a question. I read some- and everywhere the Athlon XP has a MHz limit of 2500. It seems to be so, but is it? I tried on my own to find an answer, and below is a result of that, but...
Why I don't ask AMD?! Before asking well-paid and intelligent people, I thought I should try the forum.
Speed limit
Athlon XP and Sempron reached a speed limit
The main difference between the socket A processor nowadays seems to be in the architecture of the cache memories. The speed does not pass 2500 MHz. Why is that?
The first Athlons came in 1999. Their advantages compared to their competitor are/were the number of pipelines and calculation units:
- Three decoders for translating the complex but fundamental CISC-instructions into RISC-instructions. The processor has no problem working with the short and simple RISC-instructions.
- Athlon can have 72 instructions simultaneously, (Pentium III 40, and the earlier K6 only 24).
- Very competent FPU:s, three of them, and as FPU is better at calculating decimal numbers than the main ALU, it makes Athlons good at 3D graphics – where there are lots of that kind of mathematics when producing polygons.
In the beginning Athlons had external Level 2 cache. The cache sat on a slot beside the processor, and the architecture was called slot 1. With XP this changed, both Level 1 and Level 2 cache were built into the processor, and we got the socket A kind. Athlon XP was also built with thinner lines connecting the transistors, and got the ability to handle new instructions, got a better data pre-fetch technology, and an overheating protection.
So what’s the problem? Speed it up!
Well, one bottleneck lies between the processor and the RAM memory, the Front Side Bus (FSB). The processor is much faster than the RAM and process data as they come by. To keep the processor busy mainly Intel invented a sort of pipeline, or ladder. The processor is working on every step.
Data is sent from hardware, like sound data or network data over the PCI-bus, graphics data over the AGP-bus, hard-disk data over the IDE (PCI-/SATA) bus, etc. The data comes in ones and zeroes in little packages, which make up complex instructions. For the processor to be able to efficiently perform the instructions they need to be sized down to simpler instructions, from CISC to RISC. (CISC codes is such a fundamental part of the PC history they must remain.) The sizing down is done in the very beginning of each pipeline. In later steps of the pipeline, the instructions are interpreted further and performed.
Early processors needed one clock-cycle per step in the pipeline, but Athlons can manage 2,5 steps, as can for example Pentium 4. With the pipelines, as said, Athlon XP can do 72 instructions at the same time. Pentium 4 however has longer pipelines – with 20 steps – and can process 126 instructions. But the efficiency of a Pentium 4 is lower, which is why Athlons are quicker at the same MHz. Apple’s (Motorola’s) G4 processor is yet more efficient.
Athlon XP has 10 steps in each pipeline for the “main” ALU processor and 15 for the FPU. The reason why there are not more pipelines is that the processor is not kept busy with the slower RAM, and a lot of clock-cycles would be wasted. What is more, there will be too many erroneous instructions, when the processor has to start over, filling the pipelines with correct instructions.
RAM is slower
This was not the case in the beginning. All ran at the same speed, say 20 MHz: Processor, FSB, RAM-memory, PCI-bus etc. By separating the PCI-bus, which had hardware connected that couldn’t work at higher frequencies, things could start moving.
In 1989 came a Pentium with clock doubling. To compensate for the not ‘doubled RAM, L1 cache was invented. But processors kept getting faster. Next thing to be pushed forward was the FSB, which for socket A boards now is increased to 200 MHz x 2 (DDR). Intel increased it even further, but as the efficiency rate isn’t increasing at the same rats, Intel has backed down from the megahertz spiral, and has followed AMD in other ways of thinking.
So is this the simple basic calculation?
Athlon XP:s can do 2,5 instruction per clock-cycle in 10 steps per pipeline x the number of pipelines. The number of pipelines is limited by the number of instructions sent and their quality, 72 instructions at the same time. Can this be the reason for 2500 MHz limit?

Ok, reality check people...
Sharp, nice explanation, but you are wrong.
the x86 instruction set (including those nice MUL, ADD and other instructions) is a CISC instruction set.
The difference? A MUL takes 12 cycles, a DIV 40 or something...
RISC was a new computing architecture. Each instruction is simpler to allow higher execution frequency.
The efficiency of a computer is judge by the work done. W= IPC x Freq
Frequency is the well known number that we can find on our beloved processors. IPC is the instructions per clock. Why is the athlon more efficient than a P4 at the same frequency? higher IPC.
How do the chip manufacturer choose those factors?
Well, the problem is that the instruction set is FIXED. x86 (or i386), the instruction set, has been defined years ago as CISC and to maintain compatibility, you have to keep it. They then included internal decoders to change those instructions to streams of RISC instructions, each simpler. Those are the ones really implemented.
How does that influence the speed of the processor? Each instruction is executed by a unit (integer unit, floating point, MMX...), the more that unit has to do for that imstruction, the more time it takes (and the more transistor). This has 2 problems:
- one is that it will limit the overall speed as the more complex the unit, the less speedy.
- The second is that it ties down the unit. If you do a div in 40+ clocks, your integer unit is tied during this time.
The answer to this problem? Pipelines.
Pipelines are splitting the tasks in simpler tasks and executing each as independant as possible.
Example: laundry. You need washer and dryer. However, some of your clothes cannot go to the dryer.
Now, you have 2 loads. If you have a combined unit that takes 1.5h for wash + dry, it will take 3h total.
If you have a washer (.5h) and a dryer (1h), you load the first load (.5h) then transfer it to the dryer (1h). While the drier works, you load the next washer (0.5h). If you need it to perform also the drier, total time is 2.5h instead of 3h. If you dont need it, it is even faster 1.5h.
This is the way intel followed. Prescott has a 25+ pipeline. The problem comes from branches. If you misspredict your branch, you have to flush the pipe.
All that to say that with its manufacturing and its architecture, AMD could not release a AXP even close to 2.5GHz. Can you overclock a good unit over that limit? Sure. Intel did not release a 4GHz and yet you can overclock some P4 up to 5GHz (with appropriate cooling).
Oh, and the technology used is 90nm or 0.09um. Athlon XP is not even that small, it was still on 130nm.
This is the smallest critical dimention (smallest trace. Usually smallest transistor width).

Smf / sometimes does not configure network interfaces in single-user mode?

From http://groups.yahoo.com/group/solarisx86/message/14785
When booting into single user mode, I often get a message
on the console
t_optmgmt: System error: Cannot assign requested addressand only the loopback interface is configured (lo0 inet, and lo0 inet6).
The system's dnet0 interface is not plumbed any more. Configuration
for the dnet0 network interface is via a static ip address; hostname
in /etc/hostname.dnet0, and and ip v4 address for that hostname in
/etc/hosts. This was a Solaris 10 x86 system, but the same problem
has also been observed on Solaris 10 sparc, and the hme0
interface.
svcs -x in single-user mode reports no problems.
Changing to multi-user mode by typing Ctrl-D still does not
configure the real network interface.
One thing that I've noticed is that smf's log file
/etc/svc/volatile/network-physical:default.log
is missing, when the nic interface was not configured.
It seems that the problem with unconfigured network interfaces
does not happen when I boot directly into multi-user mode.
Why isn't the physical interface plumbed and configured when
booting into single user mode on S10 b69?

actually during installation i selected DNS type for network giving a wrong nameserver and domain got skipped later
#getent ipnodes dns (no response)
so all these things i did and found by seeing the forum guidelines. I can see the network connection has receivinh and sent packets seems to be working but can't browse internet, also can't ping a website.
if anyone had the same problem but found the answer than kindly let me know. I am new to solaris but i am trying my best.

Thunderbolt to Firewire Adapter & New Network Interface Message

I am using the new Thunderbolt to Firewire Adapter. Why is it that every time I use it, I get the following message:
"A new network interface has been detected. The Thunderbolt FireWire Slot 2 network interface has not been set up. To set up this interface, use network preferences."
All I want to do is mount external hard drives that don't have Thunderbolt ports to my iMac, via Thunderbolt because I am using the iMac's single Firewire port for something else. The drives do successfully mount, but why do I keep getting this message whenever I connect them again?

I have no doubt what you say to do would get rid of the message for me. However, both myself and an Apple Store employee think it is odd that the message comes up in the first place. We're both curious about it, and he's going to look into it.
We tested it on a computer at the store, and found that it happens on Lion too.

Does having two networks on the same router cut the speed of each network?

I have successfully been using a FiOS and Time Capsule network for over two years. When I had it installed the FiOS service man set up a network without the Apple Time Capsule. I later set up an additional network that included the Time Capsule. My first question is, does that mean I have cut the speed potential in half? If so, can I safely delete the unsused network?

Setting up a new network - How does this look?

Hello,
Current layout of network - http://i30.tinypic.com/fkywav.jpg
We currently use this way of setting up our network and we may be moving to a new office so i'm looking at the best way of setting up the new network while we have a relatively clean slate. All wiring is done via CAT5e ethernet.
We run OS X Server 10.5 and use the following services within the building. File sharing, email, internet. We backup all machines individually with external drives but i'm looking at getting a large storage device to enable everyone to backup to one location using Time Machine Server.
I'd like to know if the way our network is currently set up is the correct way for what we need. In the near future i'd like to start using iCal sharing, and hosting websites internally for web development.
Regards
James

What you have will work; it's fairly typical network.
The physical plant, and the plans for expansion, and the current speeds and feeds are also key details when designing a network.
Cat5e? Don't skimp. Go Cat6 or better. Wiring is always around and in use for far longer than any of us want, and the cost of installation is comparatively vastly higher than the cost of the wire itself; retrofitting is to be avoided.
As part of avoiding unnecessary retrofitting, run extra Cat6 or better wiring in parallel, too. Prepare to segment your network based on business organization or on physical organization, or both. The extra runs can provide physical redundancy, and bandwidth. The incremental cost of building out with extra (spare) wire is negligible. The cost of not having a wiring run where you need it is higher.
Without knowledge of the physical plant, I'd also look at the establishment of wiring closets and such; you'll usually have a star at the core of the network in a smaller configuration, then stars at the wiring closet(s) (if any) and out at the desktop. This may be a plan now, and you have the wiring in place for the main runs to retrofit a server closet as you need it. Long wire runs out from the core are a pain. In a moderate or larger network, you'll be using the backhaul connections to the network cores; runs between server closets. (And if you may add server closets, remember the need for cooling can arise.)
Depending on your plans and your network activities, I might (also) establish higher-bandwidth wiring between the wiring closets; what amount to backhaul connections. Either used up front, or in the closets should you need to place switches further out.
Also look for corner cases, such as a business and operational environment where you'll be running a dozen or two client netboot operations at exactly 8:01 each and every morning as each staffer arrives and boots up the workstation; these cases can play havoc with aggregate bandwidth and server requirements.
You may want to consider a parallel network (whether WiFi or wired) for guest access; a conference room or conference center network. You'll almost certainly want 11G and 11N WiFi for your own internal use, too.
Yes, I usually overbuild these things. Planning and wiring are (comparatively) cheap. Installation isn't.
Backing up to a Mac OS X Server disk or a TC disk via TM is part of what you need. If you get corrupted archival volume(s) or if your RAID array is somehow damaged or lost or stolen, you're in deep sneakers. I've had a couple of TC archives corrupted; stuff happens. Plan for off-site archives.

3510 network interfaces and # of direct attached hosts

Hi,
I have 3510 array with Dual FC controllers and each controller has a network interface. I am trying to congiure both NICs with separate IPs but I only see one interface through console. How to set the 2nd interface up?
And there are 8 FC host ports but I only see 4 , I need to attach 6 to 8 hosts directly to the array and not able to see 8 channels. Need help to see all 8 channels and to maps Logical drives to all 8.
Thanks
ssgn

The array is configured to use the controllers for failover.

How to add a new network interface adapter?

Hello,
I followed this tutorial (http://www.oracle.com/technology/obe/ovm/ovmel5pvmdb11gr1/ovmel5pvmdb11gr1.htm) to set up a paravirtualized Oracle Enterprise Linux Version 5 VM on Oracle VM Server. It works fine, however I wish to add another network interface adapter (or NIC) to it, however when I try to import into Oracle VM Manager I get the following error:
"OVM-5004 Invalid virtual machine config file. -"
I don't know where the vm config file is so I can't fix that (I did a search for vm.cfg but couldn't find it). I figured since I could access the machine OK I wouldn't worry about importing it into VM Manager, so my question is, is there a way to set up the Network Interface Adapter through the command line on the VM Server (similar to how it was setup)? Or should I try and fix the "invalid virtual machine config file" error so I can import it into VM Manager and then add the extra Network Interface Adapter?
Thanks in advance,
Michael.

The vm.cfg file would be found in /OVS/running_pool/<vm_name>/ -- the default vm.cfg that ships with the template should successfully import into Oracle VM Manager. Once you have the image imported, you can use Oracle VM Manager to add an additional NIC to the VM.

UML290 & Mac: A new network interface has been detected

I have a MacBook Pro running Snow Leopard, and I just purchased a Pantech UML290 4G modem, live in an area with good 4G coverage, and I get a good 4G signal. I am running VZAccess Manager version 7.2.5, and in general it connects to the 4G network fine and stays connected. Every time I connect the modem to my laptop, Mac OS generates a "A new network interface has been detected" pop up with the option to Cancel or go to Network Preferences. Canceling makes it go away.
I also see 4 devices under System Preferences > Network:
1. Verizon UM290 (which shows connected, not sure why it's missing the L in UML)
2. Pantech UML290 USB Modem
3. Pantech UML290 USB Serial
4. Pantech UML290 USB CM
Does anyone know how to get rid of the annoying message every time I connect the modem? Thanks.

I have the same set up. Get the same messages almost everytime I start up the UML290. Not sure why I occasionally don't get it. Many others on the forum have reported this as well. For now, we live with it.
