Hi, I need to simulate (with a certain degree of control) common WAN problems like packet loss/duplication, delay and conditions of limited bandwidth. I found that NISTNet is what i need, but it seems the package has not been updated since October, 2000. This is not really a problem as I found NISTNet runs perfectly with Linux kernels up to 2.4.23 (officially 2.4.18 is the latest mentioned in documentation). What then am I complaining about ? Well, it seems that...

I have tried it briefly on a Red Hat 7.2 and it seems to work fine. I have another basic question and I would if anyone could help me out. Basically, I am trying a setup a Linux router between t...

...e diagram below. (Reason for doing this is to watch the behavior of the device under test to certain packets but I cannot control the speed of the packets from the traffic source so I need an intermediary to do that). [PC/traffic initiator] -- [bridge] -- [device under test] I've looked at nistnet, but that would only work for IP packets, and requires you to use it as a router as I understand it, which wouldn't work here. I've also looked at IET which seemed to be what I need, but unless I'm doing something wrong it crashes very badly under RHAT 9.0 and SuSE 9.0. Is there any...

hi, I am really a newbie in linux traffic control.But i have task to implement a tool similar to the nistnet tool used for netwok emulation tests but which emulates a wireless environment. I was exploring the use of the traffic control subsystem for this task.In this regard i have a few questions i need to post in order to clarify my thoughts on how to do this.I am using tcng to classify traffic and ge...

Hi all Iam planning to deploy Multiple Links using RH 9.0/ PIII 500Mhz/512MB RAM With all Patches related to Route and rest Mentioned in nano.txt Iam Running BGP 4 with all the ISP, but iam not doing Load balancing the Links Each Link have specific application and specific users. Eth0 is connected to Local Net eth1- ISP1 eth2- ISP2 eth3- ISP3 Now i want to make Specific Routes x.x.x.x

Where can I find examples of configs to emulate WANs, I am looking for slow speeds and high latencies. Thanks

Hi all, I am a newbie to linux and this is my first mail to this group. We have a PC running Centos version 2.6.9-42.0.2.EL. I needed to load a router software called Nistnet and it would not run properly. It is looking for RTC (Real Time clock) support as a module. I 've gone through the LKM Loadable Kernel module support under Documentation pages of Linux.org and did the following: located the kernel release: uname -r 2.6.9-42.0.2.EL next navigated to the /usr/...

Hi, i have a question if linux is able to do the same thing that commercial wan simulators do (which cost 7000 $ or more). Basicly i want to use the following setup. Linux Router Machine 192.168.0.1 192.168.1.1 Eth0 192.168.10.1 Eth5 192.168.2.1 Eth1 192.168.100.1 WEB Server. 192.168.3.1 Eth2
