Urgent Traffic generator.....

Can anyone tell me how to make a traffic generator?
Description of generator: I want to make a traffic generator to generate packets in order to test the network traffic.
Thx for everyone to help me...

So, if you've a list of machine IP's and the ports being listened to by each, I suppose you could write up a program that sends random data to each, possibly tailoring it to the port being written to (HTTP, Telnet, FTP, etc). Or, you could distribute a program to all machines on your network that listen on a well-known port and send data to them. I don't see why you can't just write up a shell script that pings all manner of machines on your network, maybe adjusting the packet size as you like. It shouldn't be too hard to run through your /etc/hosts file and shoot pings at the machines to simulate traffic, right?

Very high data traffic generated by Nokia Messagin...

Is anyone else seeing really high data use on their phone log following last week's Messaging outage?
Up until last week's outage, the data traffic generated by Messaging was about 5kb an hour (with no new emails sent or received). Presumably this small amount of data traffic results from the Nokia email server "pinging" the phone periodically to keep the connection open.
But after last week's outage and issues with passwords being requested etc etc, I saw that the data traffic generated by the Messaging app has gone through the roof - about 400 - 500kb an hour! Again, this is with no new emails sent or received - so theoretically is just the server pinging the phone to keep the idle connection open!
I reinstalled Nokia Messaging on my phone (E61i) - no difference - the data generated by the Messaging app is still 400 - 500 kb an hour (it stops when I take Messaging offline).
I have friends roaming in Ireland and their phone has had the same problem - the data traffic generated by their Messaging app is sky high and they have had to shut it down because of the high cost of data whilst roaming.
I also newly installed Messaging on another phone (N95) that I have, using a brand new email account and a new T-mobile SIM card, and guess what - that phone also has sky high data traffic due to Messaging.
What is going on?? Can someone at Nokia Messaging please sort this out? Anyone roaming with Nokia Messaging enabled is facing hugh data charges from their network.

The data traffic occurs in phones which are on a home network (mine in the UK) and on a roaming network (my friends traveling in Ireland). Interestingly, I've now checked with another friend who is roaming in Italy and they also use Messaging but haven't seen any high packet data issues with their phone.
The data traffic shows up in the Packet Log, as well as on the actual T-Mobile network account (plus the charges for the data!) Accessing a T-Mobile UK account online shows all packet data use - in this case, 120-150 kb every 15 minutes, whereas before last week it was 1-2kb every 15 minutes.
When I "Go Offline" with Nokia Messaging, the high data traffic stops, both on the Packet Log and network account, so I am 100% certain this is due to Messaging.

Re: How to disable MIG 7 Traffic Generator in simulation

Hi Everyone,
I was wondering how can I disable vivado traffic generator in simulation?
I have fine tune my DDR channel and need to disable traffic generator for simulation purposes, however, I don't see any option in MIG7 GUI interface, or any parameter that I can pass to traffic generator from my top level simulaion file to stop traffic generator for issuing command and putting random rd/wr data on my DDR bus.
Any idea?
Thanks,
Mike

Hi,
If you generate the IP alone there will not any tarffic gen, only example design comes with tarffic gen(right click on .xci and choose example design)
So while generating the IP there is no GUI option to disable traffci gen.
But if you attempt to link user deisgn top with memory model then you have to be ultimately careful in passign the parameters and mapping the signals
instead if you are running MIG example design simulation but wanted to drive your own tarffic, you can simply commet out tarffic gen in example_top and have your own fsm for driving the MIG user intefrace.
Hope this helps

Traffic Generator with Statistical Capability

I am looking for a traffic generator that I can use to simulate Video traffic (Qos, Packet Size, Continuous Streaming, etc.)
across the network. IP SLA UDP jitter is close but it is not a continuous stream and from viewing the documentation I'm not sure
the timeouts and frequency can be adjusted to give a continuous stream. So does anyone know of a traffic generator (software based)
that I can load on two laptops where on is the source and the other the receiver where I can pull statisitcs for latency, jitter, and lost packets?
Thanks for your help...

QoS Marking Traffic Generated by Network Device

I am working on defining QoS configuration standards for Catalyst 3750, 4500 and 6500 platforms. I would like to provide preferred treatment to some of the protocols commonly used for network management (i.e. telnet, ssh, etc...). I have no issues with classifying and marking traffic generated by a NMS or PC connected to a switch but I can not figure out how to classify and mark traffic generated by the switch itself. It won't do any good if traffic from the NMS or PC to the device is preferred but the response from the device is unmarked/best effort.
The only way that I can see to do this is to apply an input policy on the upstream device to classify and mark the network management traffic. I would prefer to do it on the device itself. Does anyone know if that is possible?
I'm assuming that any traffic generated by the switch would be ignored by an output policy, similar to the way that traffic generated by the device will by-pass access-lists. Even if this is a bad assumption the 3750 does not support output policies, so I'd still be stuck there.
It was suggested that I look into applying the policy to the control plane however on the platforms that options is available, policies can only be applied to the input. Which I believe is the wrong direction.
Anyone have other suggestions on how to accomplish this or is this a lost cause?

You can use local PBR to do this. Check out the local policy-map

Network Traffic Generator

Hi all
Could anyone suggest me a good Network Traffic Generator software (Free ofcourse or cheap ones) in windows platform? I am trying to setup a network where I can test and analyse the issues with VoIP packets under heavy traffic conditions. Please suggest!! I am struggling to find one. Thanks.

Hi ADITYA
Can you find the below?.
1- For traffic generation Windows is pretty bad, especially UDP traffic at any decent rates.
2-I would recommend the IP SLA feature in IOS to simulate VoIP and the statistics it generates are very good.
http://www.cisco.com/en/US/docs/ios/12_4t/12_4t4/htrtpvip.html
3- You can also check the following also :

ACLs never apply to traffic generated by the router

http://www.ciscopress.com/articles/article.asp?p=174313&seqNum=4&rl=1
"Another special note on Cisco ACLs is that ACLs never apply to traffic generated by the router. So, even if you have an inbound and an outbound ACL on a router denying all traffic, the router will still be able to send any packet it wants; the return packet, however, will be blocked as usual".
Is it (the return packet, however, will be blocked as usual) the case all the time ? if it is the case could you please explain ?

Thanks Rick,,,I need some clarification about the below scenario please:
suppose I have got R1 (one of many routers) with two interfaces serial0/0 and e0/0,,,the ip address for serial0/0 192.168.0.1/24
the ip address for e0/0 172.16.0.1/16.
R1(config)=access-list 101 deny ip any any
R1(config)#interafec serial 0/0
R1(config-if)#ip access-group out
R1(config)=access-list 150 deny ip any any
R1(config)#interafec fastethernet 0/0
R1(config-if)#ip access-group in
Now we satisfied the condition which it says: "where there is an outbound ACL and an inbound ACL and they both deny all traffic".
1- ((The inbound ACL will deny all traffic)).
This is obvious because any packet trys to enter the router R1, the ACL will check both ip addresses for the source (any) and destination (can be one of the interfaces belong to R1),,,,because it match the condition for ACL, it will be dropped.
2- ((In this case the outbound ACL can deny transit traffic, but can not deny packets generated by the router which will be transmitted)).
This first paragraph (In this case the outbound ACL can deny transit traffic) is fine,,,the second one which is : " but can not deny packets generated by the router which will be transmitted",,,,,,,my understanding is this when packets generated by router R1, these packets have got source ip address and destination ip address.
The source and destination ip addresses still matching the condition of ACL , why should't it be
denied ?

Traffic generator where we can configure the packets

Hi
Can you please let me know any traffic genertor which generates TCP UDP and IP packets and also where we can configure the Packet before generating the packets..For example I want to cnfigure the content of the packet..Other requirements are I want to give Source IP address and Source port Number along with Destination IP address and Destination port number..
Regards,
Sandhya

Hi Sandhya,
as a starter you might try the tool 'iperf' (freely available for a number of OSs).

How to apply LLQ QoS to traffic generate by router?

There is a voice gateway at the remote site, the voice card connect to the local pstn, for qos, the router must prioritize the voice traffic which is generated locally.
So is there any idea?

No, it doesn't work. please see below:
R2#sh ip local policy
Local policy routing is enabled, using route map QoS
route-map QoS, permit, sequence 10
Match clauses:
ip address (access-lists): IP_QOS_5
Set clauses:
Policy routing matches: 11060 packets, 950804 bytes
Local Policy match many packet of IP prcendence 5 or RTP traffic. But... CBWFQ only match a little RTP packet...
Class-map: Voice (match-any)
5 packets, 458 bytes
30 second offered rate 0 bps, drop rate 0 bps
Match: protocol rtp
5 packets, 458 bytes
30 second rate 0 bps

Traffic Generating using Smartbits

How to make SmartBits 6000C generate Ethernet traffic from LabView?
I have a DLL for SmartBits and I'm able to connect it.
Could someone advise something?

There is explanation on how to Control an Instrument. The function HTGetStructure is mainly used there. As far as I understand I have to use similar approach using function HTSetStructure (in order to set up transmit parameters) isn't it?
You will need to review the documentation for the SmartBits dll in order to determine which functions you will need to use.

Urgent - SAP generated structures (like /BI0/C_00**) are missing.

Hi Guys,
I am working on a mySAP upgrade project (4.5b to ECC6).
After BAT box built ( refersh from Prod box and then upgraded ), I find that there are some SAP generated structures missing. These structures like /BI0/C_00**, such as /BI0/C_0053 ("Extr. struct. version 0001 of DataSource 2LIS_02_HDR") missed, while corresponding generated program /BI0/LQI2LIS_02_HDRU02 still refer to that structure, so generated program /BI0/LQI2LIS_02_HDRU02 is invalid. And there's no delta queue in RSA7.
Then I executed initial loading on 2LIS_02_HDR, it worked fine. But while executing delta loading with data, it dumped for structure missing. And while I try to see content in delta queue of 2LIS_02_HDR ( using RSA7), it also dumped for same reason.
How can I fix such missing structure?
Btw, I know that such structure and program are generated by SAP while executed delta loading. And it can be removed while delete corresponding delta queue in RSA7. But my scenario is currently structure missed while program still exists with invalid status and no delta queue in RSA7.
Expect your suggestions.
Thanks,

Urgent: Forms generated from Designer not loading on 9iAS

HI,
I have generated a form using designer 2000, when I try to run
the form on the web it says that the ofgcall library is missing,
though the form runs when executed from the form builder.
other question is.
when I copy the .fmb file to any other destination, and try to
run, it refuses to create the .fmx of the file saying cannot
create the .fmx ( error: frm-30087 ) , I checked the error but
unable to find the described error, as I am logged into the
system and Administrator and the directory in which I m working
is fully accesible and there is sufficient space.
any please help.

Even I faced the same problem. This code works on Windows 95 but gives error "User Defined Exception" when running the same form on Windows NT. May be the API function behined this function call is a primitive one.

URGENT: Problem generating Client of BPEL process using Axis WSDL2Java

But i can't generate it. I got the problem
